You can predict someone's age by a lack of diversity in their gut bacteria.
Hannah Kleinfeld
Without addressing the gut, there's just so many other things that you can't really address, like you can't calm down, low grade inflammation in the body if you have leaky gut and you keep spewing toxins into your bloodstream. So it's all connected. But the gut is a huge foundation to even things like that.
Dave Asprey
You already know your gut controls more than digestion. It shapes your brain, your immune system, even your metabolism. But here's what no one's telling you.
Hannah Kleinfeld
Unhealthy human or in an unhealthy gut, for example, you have your good bacteria, then you have opportunistic bacteria.
Dave Asprey
You're probably still doing it wrong. You take probiotics, but then they don't work. Sometimes you eat fermented foods, but they're not enough. You try to heal your gut the way I did, but the problem isn't what you think. Hannah Kleinfeld has spent years inside the microbiome industry breaking down what actually shifts gut health at a biochemical level and why a huge number of these so called gut health products really don't work. Your gut bacteria actually make decisions for you. Cravings, mood, sleep, that's your gu. Today you'll learn how to take that power back and the one upgrade that actually fixes your microbiome, maybe even for good. Because if you don't control your gut, your gut controls you.
Hannah Kleinfeld
70 to 80% of our immune system originate in the gut. And I know that if my gut is not working properly, my brain also won't be working properly. So if I started by optimizing my brain, but my gut was a mess, I really wouldn't be making any progress.
Dave Asprey
People talk about there being a gut brain and sometimes a heart brain and then a brain brain. Is there a connection between the gut brain and the heart brain that you're aware of? So ask yourself who's really in control? You're listening to the human upgrade with Dave Asprey Hannah. If you had a choice, you had to optimize either your brain or your gut. Which one and why?
Hannah Kleinfeld
I would optimize my gut because I know how closely the gut and the brain are related and I know that if my gut is not working properly, my brain also won't be working properly. So if I started by optimizing my br but my gut was a mess, I really wouldn't be making any progress.
Dave Asprey
If you fix your brain, does it also fix your gut?
Hannah Kleinfeld
No. But if you fix Your gut, that will have a very positive impact on your brain.
Dave Asprey
Okay. People talk about there being a gut brain and sometimes a heart brain and then a brain brain. Is there a connection between the gut brain and the heart brain that you're aware of?
Hannah Kleinfeld
Ooh, I'm. I don't think I'm aware of it. But, you know, you could argue that if your gut is leaky or inflamed and you have toxins and other bad substances leaking into your bloodstream, and your heart is filth, your heart literally pumps your blood, then of course, that would also be impacting your heart and really pretty much any other organ in your body.
Dave Asprey
There's definitely a vagus connection, the vagal nerve, and then when the gut's leaky, you get the lipopolysaccharides, and those create systemic inflammation, including in the heart and the pericardium, including. And so when the gut's off, you're going to feel it emotionally in the heart, and you'll also feel it with anxiety in the brain, at least in my experience. Why is the gut important for you?
Hannah Kleinfeld
Wow, that's a big question for me. I mean, the more I understand about the gut microbiome, if you take my journey back to kind of where this all started, I had a really bad case of Lyme disease in my early 20s. And for anyone going through that, it involves a lot of. At least back then, it involved a lot of antibiotics, months of it. Months. The Lyme itself destroyed my gut, amongst many other systems in my body. And throughout this experience of repairing myself and my body and kind of recovering not just from the Lyme, but also the after effects of all the medications, I really learned that my gut was such a foundation to helping me get my energy back and helping to really get me back to health. And that really sent me on this path of my wellness journey.
Dave Asprey
I had really severe toxic mold, which at the time, if I was exposed or re exposed within a day or two, like the lining of my gut would shed and just my digestion was ruined. And I also had active Lyme disease, which I think 90% of the time is a root cause for Lyme. So it's funny, you treat the mold, most Lyme will get better without antibiotics, necessarily. And I was also on antibiotics for 15 years because of chronic sinusitis and strep throat when I was a teenager. And so my gut was wrecked, similar to you, mid-20s. I'm like, what is wrong with me? My brain doesn't work, My gut doesn't work. And so we're both motivated by this. Let's not let other people go down that path unless they really want to. I've seen such an explosion in our knowledge about this. First, there's probiotics, and I've been this for 25 years, various flavors, some work, some don't work, some you don't know. And some of them actually made symptoms worse. And then we come up with prebiotics. And then I've covered the launch of some of the latest postbiotics, and now we have parabiotics out there. What is the difference between prebiotic, postbiotic, probiotic and probiotic? Right.
Hannah Kleinfeld
So probiotic is the live, beneficial bacteria. The definition of a probiotic is beneficial bacteria conferring a benefit to human health or to your. To your health.
Dave Asprey
Right.
Hannah Kleinfeld
And so that's the probiotic. The postbiotic is the things that are made by the probiotics. So our good gut bacteria make things like butyrate, short chain fatty acids and other helpful compounds that our body then uses. That's considered a postbiotic. A prebiotic is the food for our probiotic bacteria. So that's, you know, things you can get from your diet, things in, you know, good fiber, but it's also things that you can take as form of a supplement, as a prebiotic supplement. And then you actually also have symbiotics which are the combination of a prebiotic and a probiotic into the symbiote synbiotic. And there the idea is you are adding some prebiotics to your probiotic supplement to one, feed the bacteria in the supplement and two, give some of these good fibers also for your intestines.
Dave Asprey
What about parabiotics? I've seen a few of those on the market lately.
Hannah Kleinfeld
Yeah, that's actually a term that's new to me.
Dave Asprey
This is the idea that if you take dead bacteria that they will have a signaling effect, kind of like taking a prebiotic where they're going to be a signal to your bacteria to do it. And it, it can be kind of confusing. And I like to think I've spent probably $200,000 on probiotics or prebiotics over the last 20 something years. And that seems like a lot of money. I've spent two and a half million dollars over 20 years on my longevity program. You don't need to do that every year, I don't think. Although maybe it would be nice or maybe it wouldn't be. So having tried all these things, this is one of the areas that actually is most confusing for me because how the heck am I supposed to know if a probiotic actually works or not? How do you tell?
Hannah Kleinfeld
Yeah, so that's a really great question. You know, so many people who we talk about probiotics, do they off. They often say, well, I tried probiotics and they didn't work. And one of the questions I always ask is, well, which one did you try? Because many times, you know, if you're just taking some random $20 probiotic off of a shelf at CVS, but you're not actually thinking about what are you trying to accomplish with this probiotic, it's pretty likely that it's not going to work for your situation. So what I'm looking for in probiotics and what omnibiotic really does as a company, we think about what are the health outcomes we're looking to optimize for, because we know that different strains do different things in the body. So a probiotic formulation for, you know, helping restore your gut microbiome after antibiotic intake will look very different than a probiotic formulation targeting the gut brain axis. So that's point one. It's like, how are these strains actually formulated and what are we hoping to accomplish? The second step is clinical studies, clinical studies in humans using the final formulation. So not just random strains, but the actual product that will show you. Look, we've tested this in humans, and this is the outcomes we've gotten. If you have a brand that does that, it's much higher likelihood that these products will also do that for you.
Dave Asprey
Okay.
Hannah Kleinfeld
And then the third, you obviously also need to think about the delivery mechanism of the products, because if you're just taking a beautifully crafted product, but it can't actually survive the passage into your intestines, it dies in the stomach, then that's, you know, not very helpful. So ideally also you would be choosing a brand that has tested their delivery mechanism in lab settings.
Dave Asprey
I'm really happy you talk about delivery mechanism. Some of my friends or sometimes detractors in the calories in, calories out crowd, they get really mad. I'm like, well, if it's just about calories in, what if I took all my calories and I wrapped them in a condom and swallowed them, I go, what? But you can't absorb those. That doesn't count. Oh, so absorption of calories is what we're paying attention to. That means not all calories are the same if they can't be absorbed.
Hannah Kleinfeld
This is a good point.
Dave Asprey
And it's the same thing with probiotics, because if there's 20,000 or 20 million colony forming units in a pill. When it's manufactured, they may not be there when you take it. And maybe they need refrigeration, maybe they don't. Maybe there's spore forming, maybe not. But if you put it in your mouth, are they going to change what's in the gut? I don't think the answer is the same for everyone because if you took it with a meal, there was stomach acid. Without a meal, there wasn't the reason I wanted to have you on or one of the reasons. And this, thanks for coming here in person, this episode you've been on before is to talk about the delivery system that you're using with omnibiotic, because there isn't another company doing that that I'm aware of. Why do you do it and how does it work?
Hannah Kleinfeld
Yeah, so, I mean you, you exactly said if, if the probiotics should or can't, the probiotics need to be alive in order to have that benefit in your intestines. And many probiotics are freeze dried, which means all the water is extracted out of the bacteria. And they're essentially in this dormant state. The first liquid that these freeze dried probiotics come in touch with, they will soak up because the idea is that that's supposed to kind of rejuvenate them and give them life. If, however, that is the stomach acid in your stomach, because maybe it was the probiotics were in a capsule, capsule opened in the stomach, your probiotic bacteria find the stomach acid, they soak that up and the majority of them dies and then they don't reach your intestines. With omnibiotic, our delivery mechanism, it comes in a powder. You rehydrate the probiotics in water or another neutral liquid prior to intake. Our powder also contains some important prebiotic nutrients. So essentially the probiotics wake up from the slumber, they rehydrate with the water and then they also find their favorite food. And that actually makes them really strong for their passage through the stomach acid and ensures a much higher survival. We tested this in a GI simulator. 83% of omnibiotic bacteria reach the intestines alive and active, compared to 7% on average across 10 other leading brands.
Dave Asprey
So you're getting about 12 times more live bacteria when you do the omnibiotic approach. And I hate putting powders from little packets into water. And there's like 20 companies like, here, I sent you a pack. How many of you? I couldn't even drink all the liquid with all that Stuff. So other than electrolytes, which I put in all of my liquids or just salt yours, the omnibiotic is the only one that I'm willing to do that with regularly. And the reason is that, oh, it's going to work. So I take a little packet and I mix with water and I wait 30 seconds and I get 12 times more, versus if I'd have taken a pill. So, okay, that's a trade off that I'm worth doing.
Hannah Kleinfeld
Worth it. And, you know, the other thing is you can mix it in fairly little water. I mean, some people will do a whole glass, 4 to 8 ounces. I usually do 2 ounces. And then it's really almost like taking a shot of water. And then, you know, some people like to take it in the morning first thing. If you do it on a whole glass of water, you kind of kill two birds with a stone. You hydrate while doing it. So it's, it's fairly simple to incorporate into your routine.
Dave Asprey
The other thing that I like, the reason I want to have you on is that you run one of the very few probiotic companies who has very function specific strains. And I've for years said, all right, how do I fix my gut after antibiotics? I don't usually need to take them. I don't like to take them. I just had a substantial surgery three weeks ago. I had 28 square inches of skin left over from when I was obese removed from my face and neck. That's a lot more than you would do in a normal facelift. This is. I did that, plus a bunch of longevity stuff. But of course, you take antibiotics when you have large amounts of skin just removed from your body. So I was thinking, okay, I have a lot of probiotics floating around because people keep sending them to me, right? And I do take a few weird, unknown strains to raise glutathione or something. But I'm like, how do I restore my gut bacteria? And it was cool because you sent me your newest strain, which is called a B10, which is specifically for what do you do post antibiotic. And something interesting happened. I literally did this yesterday. Not because we were recording today, just because, like, it had arrived. I'm like, oh, I should do this. So I took them around two. And I don't get brain fog almost ever. I don't get those kind of brain brownouts. I'm like. And I was tired about two hours after I took it. I'm like, well, I'm, I'm a little bit tired here. I laid down for half hour, did some rejuvenation things. My brain came back online, and then I got an amazing night's sleep, and I woke up and my gut function is much better than it was before. It wasn't that bad before.
Hannah Kleinfeld
Yeah.
Dave Asprey
But it was a really noticeable difference. Why, if someone takes probiotics like that, why would I have been tired for a little while after I took it?
Hannah Kleinfeld
Your body was just going through a lot. You mentioned you had surgery because of you had to take antibiotics. They definitely did something to your gut. It's possible that with these new good bacteria, that your gut was kind of going into a bit of a rejuvenation and restore mode. And, you know, you. Because you're also very tuned into your body, you just felt that as, ooh, I need to take a little rest and actually help my body kind of take that opportunity to recover and rejuvenate. And then, you know, you, as you said, you got a good night's sleep and you're feeling really good today.
Dave Asprey
It's okay if someone does a probiotic or something like that. When there's a rapid shift in the body, you can be tired for a little while. And that doesn't mean it's not working. It actually means it probably is working. But if I had taken it and I just felt like crap for days and days and days, that would have been something different. Do people get that from some probiotics on the market?
Hannah Kleinfeld
Yeah. So, actually, two things I want to say that the other thing, by the way, it's possible with, you know, we know that people after surgeries when they're taking antibiotics, it's also quite possible that your gut was just contaminated with potentially something slightly pathogenic. Pathogenic. But because you're in very good health overall, maybe you didn't immediately feel it as other people would feel it. But then when you send in a probiotic that restores and fights that off, it could have also been that that fatigue was a bit of, like, your body defending against a potential pathogen. Now, to your question, do other people get that one thing that I hear often? Actually, two things when, like, with regards to bad reactions or weird reactions to probiotics. One, people will say, oh, I'm. I started taking this probiotic, and I started getting really bloated. And then I ask, well, what. What was in the probiotic? And then you hear, well, it actually had milk. And then I say, well, are you potentially lactose intolerant? And then you can see the wheels turning. They're like, yeah, yeah, I'm lactose intolerant, I don't eat dairy. Well, if you then take a probiotic that contains milk, that could have done it and that, you know, again wouldn't go away. If you are lactose intolerant, you're going to have that reaction. The other thing though, which I think is also quite common, people who have a gut that's in not good shape, you have overgrowth of things like Candida or pathogenic bacteria. If you then take a probiotic that actually works, that changes your gut microbiome back to something better, you will see die off effects. And you know, you people see that with other conditions like when I had Lyme. When you get that treated, you experience die off. It basically makes you feel pretty bad for a short period of time. But it's generally a sign that your body is healing. It's tough sometimes to tease that apart when you're just your, your own self, kind of your own individual on your wellness journey. But I've definitely seen that and also frankly experienced it myself. When I had Lyme and my gut was in bad shape and I started fixing my gut and fixing all these things, there were periods of time when I maybe was feeling a little bit worse. But you know that it's heading in the right direction.
Dave Asprey
That idea of a healing response or a Herxheimer response, a lot of listeners have heard of that. It's the real deal. Especially if you're dealing with really bad dysbiosis or with Candida. If you kill a bunch of yeast, well, it's going to make a bunch of defense chemicals right before it dies. And then you have all the dead stuff to clean up. And there are ways to help protect yourself by having a more intact lining of the gut, which is the function of good probiotics and good prebiotics and mopping up the toxins. What is SIBO and what do you do about it?
Hannah Kleinfeld
So sibo, small intestinal bacterial overgrowth. It essentially happens when bacteria that really shouldn't be growing in your small intestine are overgrowing there. There can be many different causes. It essentially just means something is off in your small and large intestine. And actually some of our researchers from Europe, they have seen that oftentimes SIBO goes along with an imbalance of bacteria in your large intestine. And then, you know, for some reason it's kind of creating this imbalance in your entire digestive tract. What to do about it depends on what practitioner you speak with. I've spoken to some practitioners who have an Herbal protocol that can help with sibo. Other practitioners believe that it requires specific targeted antibiotics that kind of just go after those specific sibo bacteria. But in any case, if you're using something to kill certain bacteria, whether it's, you know, herbal or a real medication, you want to make sure you support your gut microbiome with a good probiotic. In this case, I would again go for omnibiotic AB10 because it has those strains that help restore and rebalance the gut microbiome after disruption. And anything like sibo is definitely a disruption to your gut microbiome.
Dr. Bryce Applebaum
Staring at screens all day is wrecking your vision and your brain. You might just think it's aging, but it's not. It's a broken eye brain connection. And it gets worse every hour you spend looking at a screen. If you plan to live to 180 and beyond, you need to protect your dominant sense. Now here's the good news. You can train your visual system just like you train your body or your brain. Screen fit is a science backed method built by Dr. Bryce Applebaum that rebuilds how your brain and eyes work together. No eye drops, no appointments, no gimmicks, just 15 minutes a day to sharpen focus, reduce fatigue, and protect your vision.
Dave Asprey
For the long haul.
Dr. Bryce Applebaum
I saw real results in just a week. If you strive for peak performance or plan to live a very long time like I do, you want clear vision to match, go to screenfit.com Dave or use code Dave to get $200 off and try it for for yourself. You'll see what I mean. Literally.
Dave Asprey
The universe is actually quantum. At least that's what quantum physics, hard science is showing us. Even though we don't really see it. A lot of things that we do in our life drains your energy and it disrupts your quantum energy. There are things you can do about it. Chronic stress, EMFs, environmental toxins make you feel bad. I think we all know that and we work to eliminate those or to reduce them as much as we can. But what if you could actually increase your quantum energy field so that you were more resilient to these things? It turns out you can. And there's a technology called Quantum Upgrade that comes in. It's a cutting edge quantum streaming service that provides quantum energy. Yeah, I know that doesn't sound believable, except it works. And it's not a woo woo concept. The team at Quantum Upgrade ran randomized double blind placebo controlled studies to get the hard data. And in one study, Quantum Upgrade as a service, completely neutralized the negative effects of 5G exposure on blood flow. Another double blind study found it makes red blood cells more flexible and improves their ability to carry oxygen. It increases ATP production by up to 29%. And those are just a few of the cool things it can do. When you sign up, you can link your phone, your home, your business, even your pet with their energy source. And the cool thing is you don't need to believe in something for it to work. Quantum Upgrade has the science, the testimonials, and now over 13 placebo controlled studies backing what they do. Even though it sounds pretty incredible, I use it because I like to follow the science. Try Quantum upgrade free for 15 days. You don't even need to enter your credit card. Go to QuantumUpgrade IO Dave and just click Pay later at checkout. 15 days. Get it a try, see what you see. A friend called me yesterday and his girlfriend has SIBO that didn't respond to the normal antibiotics for it. He's like, what do I do? Like, well, you work with your doctor, but if it was me, I would take a broad spectrum nuclear antibiotic, kill everything in there, and then take AB10 and some prebiotics and just repopulate or maybe do fecal matter transplant if you have access to that, which is quite expensive. So start out with something designed to restore things. How would somebody know whether their gut is just so wrecked that it's time to just reboot and start over versus to push it in the right direction?
Hannah Kleinfeld
With probiotics, I would honestly say work with a really skilled practitioner, do a stool test, do blood work. Just at that point if you're really. Honestly, if you're at that point where you're just not sure you know something is really wrong, but you just don't know how badly wrong it is, I would say you need some sort of lab data to help you understand. Is it just one pathogen, like a C Diff or something that's making you feel horrible? Or is your entire gut in so much inflammation and in such disarray that you might need a full protocol?
Dave Asprey
Also, it could be you're eating something every day that irritates your gut. Oh, yeah, like black pepper oxalate, something like that. You also could have parasites.
Hannah Kleinfeld
Yep. Right.
Dave Asprey
And you also could have bacterial overgrowth of bad stuff and you don't know which one it is. And so unpacking all that, it's really nice to have a practitioner. However, it's expensive to have a practitioner, so let's assume that I'm on a budget. Okay? I know I have sibo. I'm farting death all the time. I'm bloated all the time.
Hannah Kleinfeld
Yeah.
Dave Asprey
What's step one?
Hannah Kleinfeld
I would say look at your diet, because, you know, certain foods that you eat can make your SIBO worse. So there's this thing called a low fodmap diet to essentially reduce these things that the sibo bacteria feed on. I would say definitely take a good probiotic just to kind of try to restore as much balance as you can. Otherwise, I would look into some of these herbal approaches to targeting sibo.
Dave Asprey
This is oregano oil, grape seed extract.
Hannah Kleinfeld
Exactly. Things like that. I think there's even some specific formulations that are possibly called like, SIBO X or whatever. Like, things that kind of make it clear that it's specific for sibo. And then, you know, I think a good binder to help sweep some of the dead stuff out is really good.
Dave Asprey
Activated charcoal.
Hannah Kleinfeld
Yeah, something like that. And then also, as you said earlier, you know, there's other supplements that can also support your gut barrier. L. Glutamine, there's aloe vera, juice or liquids, things like that. Just anything to kind of strengthen your entire digestive tract.
Dave Asprey
So you do that and you take a good probiotic. In this case, it would probably be the omnibiotic AB10.
Hannah Kleinfeld
Yeah. And then, you know, depending on how low on a budget you are, there's also some stool tests that you can do without a practitioner, necessarily. However, I found that if people do those and then they get the results back, they're even more confused than they were before because it's hard to interpret a stool test without really understanding the gut. But, you know, that's something you could consider as well.
Dave Asprey
It's getting a little easier these days. You can take a stool sample and dump it into your favorite AI tool. And just what do I know about my poop? And it's kind of amazing. They. They do, like, an 80% job.
Hannah Kleinfeld
Yeah, right. Yeah.
Dave Asprey
What do you think is going to happen with AI and probiotics and our knowledge of the gut?
Hannah Kleinfeld
I think it's going to explode. And I think we're. I mean, we're already seeing this. There's so much research coming out every month on the gut microbiome and how it's linked to so many different systems in the body. And I think with AI and just that level of intelligence, I'm hoping that both on the testing side as well as on the treatment side, that we can get more targeted, hopefully lower costs. I mean, some of these lab tests are still really expensive. So with AI, maybe we can find lower cost alternatives and then also making it more accessible to people who don't want to or can't spend thousands of dollars working with, you know, a functional medicine doctor.
Dave Asprey
Do you think we'll ever get to the point where you can just use your phone or similar device, like, take a picture of your poop and know what probiotic you need?
Hannah Kleinfeld
Ooh, that's a good question. I don't know. I mean, you can't see microbes, so that might be a stretch, but maybe one day.
Dave Asprey
We can always remain hopeful. I always think something's impossible, but the amount of correlations we can do today, it's pretty phenomenal.
Hannah Kleinfeld
Yeah.
Dave Asprey
So it wouldn't surprise me if they're like, tell us what you ate, give us a picture of your poop, and we'll tell you. Magic. I don't know anyone can do that right now, But I would like to see just our knowledge base expand to the point we can at least be 80% of the way there. Say, maybe take this probiotic. One of the things I did do as part of my stress resilience protocol when I was having this recent surgery is I took the omnibiotic stress. And you have stress, you have detox, and you have the AB10. Am I missing? Is there another one?
Hannah Kleinfeld
Yeah, we actually have a few additional ones. We have omnibotic power, which. Yeah, you know, that one that really targets oxidative stress. Then we have omnibotic balance, which is more for, like, overall immune support. It's also really beneficial for people with constipation.
Dave Asprey
Okay.
Hannah Kleinfeld
And then we have omnibotic Panda, which is for babies and young kids as well as during pregnancy. We haven't talked about that one a lot.
Dave Asprey
Wait, this is Panda. Like, to stop strep bacteria? Kind of.
Hannah Kleinfeld
No, no, no. It's just literally the panda bear. We didn't come up with the name. That was already existent.
Dave Asprey
Got it. So it's the qn.
Hannah Kleinfeld
Yeah, it's Pandas.
Dave Asprey
Pandas is a really important thing that happens in kids when they have chronic strep throat, usually as a result of toxic mold. I know about it because I had it as a kid. We didn't know what it was called, but it gives you OCD and odd because your body makes an autoimmune response to a protein on the surface of strep bacteria that causes changes in the brain. And this is one of those things where the sinus microbiome, the oral microbiome, and the gut, microbiome, they're all actually integrated and if something's wrong up here with kids, they're likely to take antibiotics and they get more gut dysregulation. So I wish when I was a kid I would have had good probiotics because I probably wouldn't have got that panda stuff, which usually. It's a behavioral disorder that they usually lump in with things like autism or adhd. And it's, it's a different thing. Yeah, but your panda formula is just cute pandas for bears. But taking good probiotics is likely to reduce kids getting actual panda.
Hannah Kleinfeld
Yes. I mean, there's. I actually just was listening to a podcast on this in the functional medicine space and you know, they are. Those folks on the podcast were saying whenever a child, or really anyone, even an adult, approaches them with any kind of spectrum disorder, they need to look at the gut. Because without addressing the gut, there's just so many other things that you can't really address. Like you can't calm down low grade inflammation in the body if you're leak, if you have leaky gut and you keep spewing toxins into your bloodstream. So it's all connected. But the gut is a huge foundation to even things like that.
Dave Asprey
Ultimately, most of those spectrum disorders are chronic autoimmune neuroinflammation. And that always happens over time when you have a leaky gut and the wrong bacteria growing. And it can be caused by other things either cause a leaky gut or directly cause the neuroinflammation. So I've never seen anyone successfully reverse autism or even ADHD without improving the gut. Maybe it's just improving the diet which improves the gut, but quite often it's a bacterial balance.
Hannah Kleinfeld
Yeah.
Dave Asprey
Are you ever going to come out with something like the omnibiotic ADHD formula or.
Hannah Kleinfeld
Oh, that's an interesting one. I, I don't know. I'll talk to our research team. But you know, the omnibiotic stress release, because it targets the gut brain axis, we have seen in clinical studies that that also helps stabilize mood, improve mood and even cognitive focus, cognitive function and focus. So we, we actually have practitioners also here in the US who uses that with patients who are dealing with anxiety and kind of other emotional disorders. And they, many patients feel so much better taking that product.
Dave Asprey
Okay, that would make sense if it's balancing the, the gut brain axis. What would happen if someone with, we'll say an unlimited budget just sat down, said, I'm going to take all the omnibiotics Was that six of them you have now?
Hannah Kleinfeld
Yeah, six or seven.
Dave Asprey
Just mix them all up in a glass of water and take them. Is that worth doing or should you just pick the one or two that are most likely going to work for you?
Hannah Kleinfeld
Yeah, so first of all, I would say don't mix them in the same glass of water because, you know, you don't want the bacteria from one of the formulations potentially compete in the same glass of water for nutrients with another formulation. We know that bacteria can either work together in teams or they can compete for the same resources. So I personally often take one of the probiotics in the morning and one in the evening. I generally think about two is fine. After that it's, it's probably just a lot to keep track of. And you know, usually most people, if I say, okay, what are the one or two things in your health that you're really looking to optimize? We can narrow it down to two.
Dave Asprey
Omnibiotic formulations I've got on the counter downstairs. You can see it when we, when we finish. I've got power, stress and AB10 and I just kind of randomly take one of them. I'm not sure that I'm that structured. About twice a day. Yeah, I just, whenever I think about it, and I think my stomach's mostly empty, I just kind of mix one with water and chug it. Like I said, a two ounce shot.
Hannah Kleinfeld
Yeah.
Dave Asprey
Okay. What percentage of what's in one of those packets is prebiotic versus the actual bacteria?
Hannah Kleinfeld
The majority is. Well, actually that's a good question, I would imagine. Or I think the majority is the pre, the probiotic bacteria. And then we mix small amounts of prebiotics in. So what's really important, people ask us this all the time. They say, so is omnibiotic also a prebiotic supplement that I would take if I'm fiber deficient? The answer to that is no. A fiber supplement, a prebiotic supplement, usually you take like bigger scoops and it's just fiber. It's helping to, it's helping you meet your fiber requirements. The prebiotic nutrients in the omnibiotic powder are just the right amount to feed these probiotic bacteria when they're mixed in water and during that activation phase. So it's not the same as taking a full on fiber supplement.
Dave Asprey
Okay. When people are on low carb diets, they're usually also on low fiber diets. Will probiotics work if you're carnivore or if you're on a low carb diet?
Hannah Kleinfeld
Yeah. Absolutely. I mean, I would say, you know, in that case you need to even more so you need to make sure that you're supporting your gut, your digestion. Some people who are not getting enough fiber, they suffer from things like constipation. However, you know, fiber is really important as the food source for your probiotics. So if you're not getting that through your diet, I would say at least look at ways through dietary supplements that you can increase your fiber intake to make sure that the gut bacteria actually have food to survive on.
Dave Asprey
When I was doing a lot of intermittent fasting and keto dieting, I measured the number and diversity of my gut bacteria and I had relatively low number, relatively low diversity. In fact, you can predict someone's age by a lack of diversity their gut bacteria. So I had older person's poop dynamics because of diet. So I added a prebiotic I wanted to formulating and I was getting about 40 grams of soluble fiber, no insoluble, like sawdust kind of stuff. And it quadrupled the number of species of bacteria in my gut. And I took probiotics at the time. And I think there's a case for that. There's also a bunch of people on the carnivore side are saying that there's no proof that we need a soluble fiber whatsoever. And actually in my first book I put this study in there. Collagen can be fuel for gut bacteria. So you don't have to have fiber if you get enough collagen. Have you ever looked at that? Is collagen enough to grow bacteria or should people really be taking some, some fiber?
Hannah Kleinfeld
Yeah, that's a great question. I personally am not so much into the research on that. I'm sure our, you know, scientists in Europe might have looked at that, but not something I know off the top of my head.
Dave Asprey
Good deal. It's a pretty detailed question and it's one I've often pondered and I've gone through phases where I take a lot of prebiotic fiber and phases where I don't. I think maybe that's the natural way to do it and sometimes I just do it based on how my gut feels. Yeah, okay. About five, six years ago, I invited one of the, the main scientists who ran the trial on GLP. 1 Drugs like OIC or semaglutide for weight loss came on the show. I did one low dose injection just so I could record the episode and I felt nauseous the whole time and I hated it. And I've not used it for weight loss at all. I just use food. And I've seen different reports saying that GLP1 drugs are really bad for your microbiome. Are they? And what do they do?
Hannah Kleinfeld
Yeah, this is a really hot topic right now and I think, you know, it's something that's actually not talked about as much as it maybe should be. A lot of these GLP1 drugs come with pretty significant GI side effects and that's not surprising. If you look at how these GLP1s actually work. One of the mechanisms is they slow the transit times through our intestines. So everything we eat and also our waste products, instead of being absorbed quickly and then the waste is being eliminated, it just sits there. And that creates, you know, allows some pathogenic bacteria to feast and ferment, it creates fermentation, it can create inflammation in your gut and all that, you know, signs of that would be bloating, constipation or diarrhea, nausea, all these GI issues. So yeah, so that's one issue. It's just, just the working mechanism of these drugs can lead to these GI issues. The second thing, and for me, much more interesting thing, is GLP1 medications can also lead to what people call secondary dysbiosis. So what does that mean? That means it's dysbiosis. So an imbalance in your gut bacteria, an overgrowth of these pathogenic bacteria because you were taking the medication. And again, the reason behind that is the food is not being moved or all your waste products who are not being moved through your body as fast as they're typically moved when you're on these drugs, just creating this environment for fermentation, inflammation and overgrowth.
Dave Asprey
Oh, so you take a GLP1 drug, it slows the speed of food moving through the gut, so then the food spoils and then you got dysbiosis you wouldn't have had if you didn't have the drug.
Hannah Kleinfeld
Exactly.
Dave Asprey
Is there something to be done done about that?
Hannah Kleinfeld
Yeah. So researchers in Italy actually just looked at this. I had the honor of speaking with them a few weeks ago. They were, they're running a weight loss clinic and they use GLP1s all the time. And what they saw is that if they combine omnibiotic keox in, in Europe, there's a half dose version of that called omnibiotic Metatox. But in this, in that sense, it's the same as Omnibody Ketox. If they gave that to the patients before, like about four weeks before starting the GLP1 and then throughout the whole duration of taking the GLP1, they reduced the risk of that secondary dysbiosis. And they actually also significantly reduced the side effects that these GLP1s generate in people.
Dave Asprey
Okay, I've been putting together this kind of stack of, like, what do you do if you're going to take GLP1 drugs? And I want to be really clear, being obese is really dangerous. And there's people saying, oh, these GLP1 drugs, they were so unsafe compared to being as fat as I was. They're not unsafe, but they have side effects. So you could say, I'm going to choose to lose the weight by any means necessary, and I will deal with the side effects in a scientific way. So if you go to daveasprey.com GLP, the protocols there, that includes mitochondrial enhancement, and I'm going to ask the team, guys, can you add the omnibiotic to our protocols that people can get from that? Because it's just really important. I think it's fantastic. If people are going to lose weight, I'm like, don't lose your muscle, don't lose your bone mass, don't get dysbiosis, don't wreck your mitochondria, but lose the weight. So this is a really cool addition to the protocol. So thank you.
Hannah Kleinfeld
Yeah, you're welcome. And, you know, I think it's so important because as you said, it's like, if people choose to do that for their health, at the very least, making sure that you go in understanding how that impacts your body as a whole, and then that gives you the agency and the power to do something before it then turns into a further issue. I think one of the biggest concerns in this dynamic for me is say someone is really dedicated to losing a lot of weight. They choose to be on GLP1s, they experience these side effects, they go through this. It's not an easy. To me, it doesn't sound like an easy journey, but then they wean off, but their gut in the process is wrecked because of that secondary dysbiosis. We know today that our gut microbiome is so important for overall metabolic health. You don't want these people then coming off of the GLP1 and being left in a worse spot than before in terms of what their own body is doing for them, their metabolism. So I think for me, that's. It's just about empowering people to know what are the impacts and then being able to proactively work against them.
Dave Asprey
It makes so much sense that you want to heal your gut and Heal the rest of your biology after you go off the drugs. Or in my case last week or maybe actually two weeks ago, I started using a third generation GLP1. I am around 5% body fat. I have no need to lose weight. I'm using an extremely low dose and I'm doing it for longevity reasons because they have all kinds of anti Alzheimer's and anti, even cancer, really good effects at tiny, tiny doses that wouldn't cause weight loss. So I'm experimenting with that. I don't think that's going to harm my gut, but I take omnibiotic and a bunch of other gut health stuff anyway, so I'm not that worried. Do you use GLP1 drugs?
Hannah Kleinfeld
No.
Dave Asprey
Okay, got it. Would you use them for longevity if there was good science?
Hannah Kleinfeld
I'm not sure I'd want to understand honestly how it impacts the body overall and also for the long term. But you know, I do think I'm. Well, I can say for myself, I'm very interested in making sure my own metabolic health is where it should be and where I want it to be and understanding even more. So now where we have these new clinical studies coming out, just understanding how a dysbiotic gut can increase insulin resistance, can mess with your hunger and satiety hormones. Like there's so many things that connect the gut with our metabolic health that for me, as I'm interested in metabolic health, I of course also need to look at my own gut.
Dave Asprey
You're reminding me of a really cool and little known fact about gut bacteria. There's a group of, actually there's several groups of online nutrition bullies. You have the hospital food, American dietitian people. And most of the time you're like, dude, you're responsible for McDonald's and hospitals. Don't talk to me, that's not a problem. And there are good functional dietitians out there, just fewer. Then you have the low carb angry echo chamber crowd. And then you have the vegan bullies and you have the keto bullies, right? And there's a couple carnivore bullies, but not as many. Right. And they're just like anyone who doesn't agree with me and it's like just these like shouting chambers. So some of the low carb or keto guys were saying, dave, you know, you don't have whatever degree so you have to have a mechanism to explain my calories and whatever. So I said, you know, I'm happy to give you the mechanism. I'll publish it my book because you don't know about it. So then I published the book and the guys comes like, dave, you said you were going to tell us. And I responded, fiaf f I A f. Right. And he kept trolling me and I'm like, dude, I just answered your question. You don't know what it is. And it stands for fasting induced adipose factor. And it turns out your gut bacteria, they're sending this factor into your liver. Your liver is supposed to make it, but your gut bacteria, they're like, well, we don't have any food, so let's manipulate your behavior by secreting extra feoff to give you more hunger than you should have if you don't have the right bacteria in your gut.
Hannah Kleinfeld
Right.
Dave Asprey
And this is a mechanism by which fasting is helpful. And also having healthy gut bacteria is really meaningful because they're not going to amplify your hunger signals with fiat. And so I think the more you fast or the more using GLP1 drugs, the more important your probiotics are. Does that make sense?
Hannah Kleinfeld
Yeah, I could definitely see that. I mean you, with either one of these, you just want to make sure that you're counterbalancing some of those effects that these interventions are having.
Dave Asprey
When I had this recent surgery, they gave me a painkiller that had a risk of GI bleeding and a lot of the non steroidal anti inflammatory drugs do that, things like ibuprofen, aspirin, all that stuff. And I didn't need really any painkillers for the most part. It was kind of ridiculously not painful, even though it looked really bad on Instagram. And. But I did take it for a few days and they gave me a proton pump inhibitor with it. And I threw that away because for you, proton pump inhibitor drugs seem really nasty. But I replaced it with another stomach acid blocker called Pepcid AC, which is an H2 blocker that does something similar. And we know that blocking stomach acid, when you take an ibuprofen or an naproxen or aspirin, it's going to stop the GI bleeding. Why are proton pump inhibitors so bad for you?
Hannah Kleinfeld
Yeah, well, you know, just. I'm guessing everybody knows here listening to this, but proton pump inhibitors really are generally one of the solutions for people who have acid reflux or heartburn or even, you know, gastritis, things like that. So it's when something is off in your stomach and what we don't necessarily think about is that the stomach is one of our first gatekeepers. To what? To everything that we put in our mouth. And one of the biggest purposes of the stomach acid is to kill things that we don't want in our system that could make us sick.
Dave Asprey
Oh, yeah.
Hannah Kleinfeld
So if you're taking an acid blocker or a ppi, you're lowering the amount of stomach acid that's in your stomach, which essentially makes it so much easier for those harmful pathogens to get into your body. And what we actually see is many people who are on PPIs, especially over a long period of time, they have dysbiosis and imbalances in their intestines because they have less of this stomach acid that can keep those unwanted pathogenic bacteria out.
Dave Asprey
One of the things that I've written about in my longevity work is that as you age, your body naturally makes less and less stomach acid. So older people have more gut issues because they don't make enough stomach acid. A symptom of low stomach acid is acid reflux, because when you have enough stomach acid, there's a valve at the top of the stomach or a sphincter that'll close off and prevent stomach acid from irritating your esophagus. I had really bad issues with acid reflux in my early 20s. And of course, they gave me either. I don't remember what it was back then, but it was either a proton pump inhibitor or an H2 blocker. And I took it for a couple years, realized this is wrecking my health. And then I did the research and realized if I could increase my stomach acid, I would stop having heartburn. And the protocol for that is to take something called betaine hcl, which is basically stomach acid in a pill. So I take about 2 grams of that with every meal, which makes sure that I'm sterilizing the crap out of whatever I eat. And this is a really good idea, but I wouldn't take that if I had just taken omnibiotic. I'll take omnibiotic, wait a half hour till it's into the gut where it goes, the stomach acid stays in the stomach, and it gets neutralized when it leaves the stomach. Your bile goes in, which is highly alkaline, and takes out the acidity so that the gut doesn't get sterilized. Right. And a lot of people just don't understand. Your heartburn is caused by low acid, not high acid. And if you block all acid, you won't get heartburn. But then you stop digesting protein, and you can, like, poop your food out undigested because there was no acid. It's really a bad thing.
Hannah Kleinfeld
Yeah, it's all about balance. You want the right amount.
Dave Asprey
What about things like Pepcid, the H2 blockers versus proton pump inhibitors? Why are PPIs even worse than something like a Pepcid?
Hannah Kleinfeld
I'm actually not sure. The detailed research on it. Yeah, what, what's your take?
Dave Asprey
It looks like they increased SIBO much more.
Hannah Kleinfeld
I could see that.
Dave Asprey
And that the proton pump is involved in many other processes. So my long Covid or mast cell protocols, or just for general mold and chronic fatigue, or even Lyme, like, you should block your histamine response for six months. And that means you take a Pepcid, which is an H2 blocker, and you take a claritin, which is an H1 blocker. So you block two of the three kinds of histamine so the body can chill out, the immune system can. Problem is you'll have no stomach acid. So during the protocol, every single meal, religiously you take betaine, hcl so you don't lose the problems with the gut. And I've seen people just have crazy results. Usually it's about five months in because that's the amount of time it takes for your mast cells to die and be replaced with new ones. But I wouldn't want to use a proton pump inhibitor because it'll have systemic effects.
Hannah Kleinfeld
Yeah, that's smart. That's a really, that's a really good approach. I like that.
Dave Asprey
And of course, if you did that and you weren't taking probiotics, your gut's going to probably be wrecked anyway. And if you're working on healing something like chronic fatigue or mold or Lyme, you can just guarantee that your gut is wrecked. And the reason you can do that, if it's mold, mold makes antibiotics. That's where penicillin comes from. That's where most of them come from. So if you're breathing the stuff in, there's a pretty good chance your gut bacteria were disrupted.
Hannah Kleinfeld
Yeah.
Dave Asprey
That means you have to take a probiotic to bring them back online where you want it to be.
Hannah Kleinfeld
Right.
Dave Asprey
If you're using a protein powder, you need to hear this. The Clean Label project recently tested 160 top selling protein powders in the US and they found that nearly half exceeded the Prop 65 threshold for lead. Oops. That's why I love Puree's PW1 whey protein. The clean label project does third party testing on every single batch against over 200 contaminants. Puree is the only, only clean protein brand in the US With a Clean Label Project Transparency certification. And every bag has a QR code so you can scan it and see what's in it. And of course, it comes from pasture raised cow's milk with no hormones, GMOs, no pesticides, and it doesn't have the metals, pesticides and harmful toxins that are in a lot of common protein powders. So switch to PW1 right now. Listeners can get 20% off the already discounted subscriptions. You'll get almost a third off the price. Go to Puree.com Dave and use code Dave. That's P U-O-R-I.com Dave. You've probably heard that I've been taking Mitopure for years, ever since it first came out. It's one of the few supplements that actually moves the needle when you want your cells to work better and your mitochondria to perform best. Mitopure contains urolithin A, which is a clinically backed MIT magic powder for your mitochondria. And it's backed by 10 years of research. But here's the fun part. It's now available in a gummy that actually tastes good. Yeah, a gummy that you want to eat. And it's not a sugar bomb pretending to be healthy. They're sugar free, they taste amazing and they deliver the same high dose bioavailable mito pure I've been using in their soft gels. And best of all, because I actually want to eat them, I take more and I feel better. So if you've been serious about your longevity stack or you just want an easier and better tasting way to get started, try the new Mitopure gummies. They're that Good. Go to timeline.comdave and you get 20% off. Are there specific probiotics that work best for mold or Lyme because you've had lime?
Hannah Kleinfeld
Yeah. Well, so I think I would always approach it from the perspective of like, where in your journey are you, if you are working, you know, for example, with Lyme, you're taking antibiotics, I would say 100% take omnibotic AB10. However, for many people who I've spoken to who had Lyme or even other, you know, mold, other things that they're working on treating, there's often a point where you are just, you're done with the active treatment, but you're just kind of in this phase of like generally repairing. And many people at that point suffer from brain fog and just really bad concentration issues and focus. And then I would say switch from something like a B10 to omnibiotic stress relief because that really targets that gut brain axis. I saw it when I was in that part of my Lyme journey. I was. I started taking omnibotic stress release, and within a few weeks, I could feel finally feel my brain come back. And I was thinking again at the speed that I was used to thinking before I got sick, which was amazing because for months I thought I for. I literally couldn't remember three things going to the grocery store. And so that was really incredible to. To see and feel. And then, you know, I think for people with mold, because when you're detoxing from mold, you're also really taxing your detoxification organs. I would say almost consider taking omnibiotic. He talks because that's our gut metabolism, gut liver support probiotic. And we've seen with Omnibody Ketox, it reduces endotoxins, it improves cardiometabolic markers. So I would say that's probably a good go to.
Dave Asprey
I just had the guys from Deliverance on the show. They make a specific set of herbs for making your liver healthy. And I take. I take those compounds. I also take. He talks and I know a lot about health and do all the things. And they do a clinical grade fibrotic liver scan. And they said I had the youngest liver of anyone they've ever measured. They said, dave, you have the liver of a 10 year old. Right. And I think it's because my probiotics are balanced. Thank you. And because I take a bunch of the right digestive stuff and because I take the right herbs.
Hannah Kleinfeld
Right.
Dave Asprey
And also because there's this weird superfood beverage called coffee that's correlated with great liver health. And I kind of do that.
Hannah Kleinfeld
Yeah. You're eating low toxin. You know, you're just general. You're not really the kind of person who would like, burden your liver with, you know.
Dave Asprey
Yeah.
Hannah Kleinfeld
Things that you expose yourself to.
Dave Asprey
I like to huff Axe Body Spray.
Hannah Kleinfeld
You know, and have the. The plugins, the scented plugins everywhere. Yeah.
Dave Asprey
Drives me. Or like the. The Ubers.
Hannah Kleinfeld
Yes.
Dave Asprey
I'm to the point where I'm like, see that little pine tree? Could you put it in your glove box, please? Like it's giving you small testes. And I tell the drivers that. And then they.
Hannah Kleinfeld
Oh, and then that's a good one.
Dave Asprey
Actually. I don't say that. And I have a high rider rating, but I'm just like, hey, man, it gives me a headache.
Hannah Kleinfeld
Yeah, please.
Dave Asprey
And they're usually pretty cool, but yeah, that stuff matters over time. How much do you think glyphosate in our food is disrupting our gut bacteria?
Hannah Kleinfeld
Yeah, I mean, I think a lot of the toxins in our video glyphosate is being sprayed on so many crops and it's, it's a, it's a pesticide, it's supposed to kill things that like mold and other things that would otherwise grow on, on these crops.
Dave Asprey
It's an herbicide, right?
Hannah Kleinfeld
Oh, an herbicide, sorry, yes, an herbicide. But still it, it's supposed to kill.
Dave Asprey
It'S also an antibiotic.
Hannah Kleinfeld
It's an antibiotic, yeah. So I mean, yeah, I think it's, you know, ex. We've, we see when you look at the health of our gut microbiome today versus a few, you know, even 30, 50 years ago, it's not trending in a good direction. And when you look at that, just the sheer amount of environmental toxins we're exposed to on a daily basis, it's wild. And all of that also impacts our gut, our again, the gut bacteria are living things. So you know, we just, we can't forget that.
Dave Asprey
It drives me nuts because Bayer, which is a company that was one of five companies that split out of Ag Farbin, which is a Nazi era chemical company with not a clean history, we'll say, but Bayer splits out. They understand biology and humans very well. They have all kinds of people studying the gut. They buy Monsanto and then they have the gall to look you straight in the eye and say glyphosate doesn't have any effects on human health because it only affects the shih tamake pathway which is only in bacteria, so it won't affect humans. And you're like, guys, your own research people at the company that bought Monsanto, you know damn well that we are dependent on the bacteria in our gut. And to say that we're separate from our gut bacteria is scientifically fraudulent at that point. And that's why there's $10 billion and counting of settlements against Bayer and Bayer, you need to clean up your act on this stuff. And I hope, I hope to hell that as long as you are selling glyphosate or its derivatives that you get sued into oblivion. And I also hope that the farmers who spray your stuff, mostly large industrial farmers, are also held accountable. And I think there might be a new regime in the US who's going to make that happen. So stop making the stuff that's poisoning my gut bacteria, because I take that personally. What do you think? Accurate?
Hannah Kleinfeld
Possibly.
Dave Asprey
I mean, look at you preserve your brain.
Hannah Kleinfeld
Yeah, I mean, we want to be conscious of what we're putting in.
Dave Asprey
Don't piss off, Bear.
Hannah Kleinfeld
No, we want to be conscious of what we're putting into our body. And, you know, I think one of the things that I just, as a consumer, struggle with is understanding what we're putting into our body. Because, you know, there is. Yes, there's organic, but what does that really mean? And, you know, unfortunately, I wish I could grow all my own food and really know, but even then, how would I know that, you know, what's in my air and what's in my soil? So I think just being more conscious of what we're putting in our body, but I think also kind of understanding that there's certain things that are a little bit outside of our control, and then just figuring out, what can we do to biohack our health. What are the supplements? What are the things we can do with diet, with stress management to just kind of dampen these effects from our environment.
Dave Asprey
Would you be up for talking with your research scientists about making a probiotic that specifically helped people handle glyphosate or gluten better?
Hannah Kleinfeld
Yeah, I think that's very interesting.
Dave Asprey
So one of the things that I've noticed, I've been traveling a lot around the world talking about longevity, and I was just in Dubai. They use European wheat now. It's a different species of wheat than American wheat. We use hard wheat here. And almost all wheat in the US Is sprayed with glyphosate, which is bad for your gut bacteria at the end of the crop. So it's just right in there. And they don't even, like, apologize for poisoning the grain right before you eat it. So I can go there and I can eat whatever I want in terms of gluten. I still have dairy issues there, so I can eat, like, actually, in 10 days, I eat something like two kilos of baklava.
Hannah Kleinfeld
Amazing.
Dave Asprey
My blood sugar might have been high, but I'm like, this is so good. And I'll just take some herbs and berberine and whatever else, and I'll just manage it. No gut issues whatsoever. And I come back here, and I eat, like, a teaspoon of American wheat, and my gut just gets shredded. And I know it's not just the gluten. Right. I take gluten enzymes, too. So I think that there's something that you can do, if that's a target with probiotics, to actually help Americans be more resilient as we work on fixing our soil. And Our food supply. I would spend a lot of money personally on that if you could let me eat like a piece of bread at a restaurant in the U.S. i don't think it's going to be good for me, but I'd like to be able to.
Hannah Kleinfeld
Yeah, I hear you. I miss gluten. I, I, since my lime, I'm very gluten intolerant. And I dream of some of the things I ate when I was a kid. And, you know, I grew up in Germany, and there it's just glutens everywhere. And it's such a big staple of, I mean, in a lot of places in Europe, it's such a big staple in the diet. So I miss it.
Dave Asprey
I did something last week, I was like, you know, if I can eat, if I can eat it there, how hard could this be? So I bought some organic French wheat, which doesn't have glyphosate in it, and it's the good species, and I made sourdough myself and I ate it with zero negative health effects. Wow, that was crazy because I'm someone who could not touch gluten and I. My probiotics are balanced and I'm taking gluten enzymes and all that. I don't think I'm going to do that on a regular basis. But what's interesting is white flour is very, very low in oxalate, which is another compound that shreds the gut. Are you equipped to talk about oxalate and digestion?
Hannah Kleinfeld
Not in depth.
Dave Asprey
Okay, good. We won't go too far in that direction. We'll just say that there's a good number of people who will have like a superfood smoothie with almond butter and spinach and kale and beets and all these things. And then they're like, oh, my God. And then they have to poop. And like, there was razor sharp calcium crystals in the gut that caused a lot of those issues. And then their joints hurt and they get brain fog. I was one of those. You get skin stuff. But we think long ago that humans could handle more of that because we had something called Oxalobacter formigenis, which is a species. I know one guy years ago who ate some duck poop to try and get those. Probiotics do not do that. You'll get parasites. That's disgusting. And there was a company in Europe who was trying to make a probiotic with this, and it was available for a year, and then they took it off market and wanted to make it into a drug for kidney stones. So I don't know what happened to them. And I don't think bacteria in the gutter, that big of an issue for that. But I suspect that if we could go back and look at the human microbiome for 100 years ago, it might be different.
Hannah Kleinfeld
Yeah.
Dave Asprey
So I'm interested in creating this superpower. I want to eat garbage.
Hannah Kleinfeld
Yeah.
Dave Asprey
And still have a functioning gut. Why can some people, including some of my friends, just eat the worst, crappy processed foods? And it looks like they digest it, they don't get problems. What's up with those people?
Hannah Kleinfeld
I don't know. I think they must have a pretty good gut microbiome. And then maybe also, I don't know, genetics.
Dave Asprey
It's not fair. So I'm going to change my genome and change my microbiome until I can eat a Twinkie. Not that I want to eat a Twinkie. I just want to know that I have that level of resilience.
Hannah Kleinfeld
But, you know, the other thing that I sometimes think is people have different thresholds for knowing what good feels like.
Dave Asprey
Oh, yeah.
Hannah Kleinfeld
And I think for some people, like, I think this was even true in part for me before I went through my whole Lyme journey and just became so much more aware of my body. I thought I was feeling good. But then you. Until you unlock that next level of, like, truly energized, waking up feeling really good in the morning, you might think that that's just your baseline, but really, that's not your baseline. It's just your baseline while you're eating gluten and processed food and junk food.
Dave Asprey
A fair point. A lot of people have no idea what they're capable of because they just say, I always feel this way. That's not how you're supposed to feel. I was one of those. You can actually feel peaceful, not angry. You can.
Hannah Kleinfeld
Yeah.
Dave Asprey
Walk around with all the brain energy you want. Because I never had that when I was younger.
Hannah Kleinfeld
Okay. Yeah.
Dave Asprey
What about alcohol? I am not a fan of alcohol. I think it's bad for you. And I'll drink it if it's older than me, which is basically a break. So, like, once a year, maybe.
Hannah Kleinfeld
Right.
Dave Asprey
And I know that I'm going to feel crap the next day. What does alcohol do to gut bacteria?
Hannah Kleinfeld
Yeah. So it's. It's a really interesting topic because you just, in the last few weeks, really saw it kind of resurface in the media. And I think what I find most interesting is even my generation and younger generations are considering, you know, dry January or even stopping drinking. Alcohol at all. And I think it's because they understand more and more how it makes you feel when you look at your gut specifically. Alcohol can disrupt our gut microbiome is even in moderate quantities, it can change our bacteria, kill some of the good ones, increase inflammation. And I think especially that increasing inflammation, this is really where you start running into issues. Once you have inflammation in the gut, your, your gut barrier becomes compromised. You're essentially developing leaky gut. And with that more toxins and unwanted things leak into your gut, into your bloodstream. And you know, if you drink every now and then in moderation, I think your gut is more likely to be able to recover, especially if you're eating pretty well and not kind of adding more fuel to the fire through your lifestyle. But the problem is when you just can't really get that inflammation under control, you have full on leaky gut and then it's just this perpetuating cycle of low grade, low grade systemic inflammation which we know has been implicated in so many chronic issues down the road.
Dave Asprey
I've seen some research is in mice showing that if they put 3.5% alcohol in their water, so this is a pretty weak solution that they had lower insulin, lower fasting blood sugar glucose, lower obesity, better metabolic function, a slight extension of life. And I'm thinking that's interesting, but it's chronic, very low dose, so that would modulate gut bacteria via a hormetic stressor. But I don't think doing a shot of vodka is, is going to help. Yeah, in fact before this I took some mushroom extract in alcohol and I was sitting here going, why is my gut feel weird? Oh, it was the alcohol. Right. So I, I just don't think, think it's good and the science is that it's not.
Hannah Kleinfeld
And you know, one of the things though, I mean I've had people, especially in January when they're contemplating dry January and things like that. I've heard people say, well, if I do want to enjoy the occasional glass of wine or whatever it might be, what can I do to support my health and my well being? And you know, my typical answer is one electrolytes and just hydration while you're drinking, but also the next day a good probiotic to counteract some of those impact. HE TALKS Omnibiotic heat tox supports your gut and your liver and then also just making sure that at the same time you're maybe not fueling the fire also with bad food and, and other things. So that's kind of my general advice. And then you know, if there's any other supplements you can take to support your liver, like glutathione, milk thistle, things like that. That's a. That's, you know, at least that way you can kind of, again, knowing the things that it does in your body, you can then help counteract those.
Dave Asprey
Really good advice. I also published years ago this alcohol roadmap infographic that's been, I think, copied lots of times and echoed throughout the Internet. And the idea here is that if you're drinking wine or beer, there's a lot of fermentation metabolites that directly affect your gut bacteria that your liver and kidneys have to filter out. And if it's American wine, Good God, there's 2,000 chemicals that they can put in there that are not on the label that affect microbes.
Hannah Kleinfeld
Yeah.
Dave Asprey
So maybe you should step away from the wine and sorry, for friends who own vineyards, don't put chemicals in there and announce it. And there are some types of wine, like my friends at dry farms. They launched on the show many, many years ago. There's some that are tested to be free of additives. It still though, compared to a distilled beverage like a vodka or whiskey or something, there's just less toxins that affect your gut bacteria. So I'm like, do that. Don't put a lot of weird chemicals and colorings in it. And then maybe take some charcoal. Do the things you said. Take your. He talks, take your glutathione and look, you'll probably be fine. Yeah, right. There's also zebiotic. Have you come across those guys?
Hannah Kleinfeld
Yeah, yeah, yeah, I saw you mentioned them. That's a really interesting technology as well, obviously.
Dave Asprey
Yeah. And that's not something that you guys do. And they were on episode number 1,000. It's only for something you take right before you drink. So if you do that before you drink to block one of the pathways called aldehyde, and then you take Ketox, which is there to make your liver better able to process all these things.
Hannah Kleinfeld
You'Re in pretty good shape.
Dave Asprey
Or you could just say, I saved a lot of money by not drinking and I spent it on the steak instead.
Hannah Kleinfeld
Exactly. Do. That's my approach too. Yes.
Dave Asprey
It's not that hard to do.
Hannah Kleinfeld
Yeah.
Dave Asprey
Okay. What else can work if someone's dealing with acid reflux?
Hannah Kleinfeld
Yeah. So, you know, that's actually a really exciting topic to me right now. We just introduced two new products here in the US they're already have been around in Europe for a few years. They're called caracol and caracol gastro.
Dave Asprey
Oh, cool.
Hannah Kleinfeld
And the caracol gastro specifically is, is designed to help people with acid reflux and heartburn. And what it does is it's a highly potent papaya concentrate. It comes also in a pouch, so it's almost like a mousse, like applesauce.
Dave Asprey
Okay.
Hannah Kleinfeld
It's prepared according to traditional Chinese medicine and Ayurvedic healing principles. And the way it's prepared, it's a really long kind of cooking, fermentation, oxidative process. It makes this papaya four times as potent as regular papaya puree.
Dave Asprey
So potent for like lining the gut or potent for enzymes?
Hannah Kleinfeld
It's actually the enzyme enzymes and the anti inflammatory properties and what they have seen in several, they've done several different clinical studies, but one cool study they actually did on pig stomachs in a lab and they could see that this caracol gastro solution coats, like physically coats the stomach and protects it from, you know, if it's inflamed, it soothes and it coats. And then they've also done a study on people with heartburn and they've shown like a 50% reduction in heartburn incidence over the course. Course of the experiment.
Dave Asprey
That sounds more powerful than aloe vera.
Hannah Kleinfeld
Yeah, it's, it's a real, I mean in Europe it's. People love it, especially people who don't want to be on PPIs, who, and who don't want to be on acid blockers and who still deal with this on, on, you know, an occasional basis.
Dave Asprey
I don't really get acid reflux on a regular basis at all or say if I do it's because I ate something I shouldn't eat. And I know why, but I'm really interested in having the thickest, most ridiculous lining on my stomach ever so that I have less autoimmunity, which has been an issue for years. Did you bring me some?
Hannah Kleinfeld
Yeah.
Dave Asprey
Did you really?
Hannah Kleinfeld
Yes, I did.
Dave Asprey
It's like, I want to try this. Of course, guys. I can't tell you whether that stuff works or not.
Hannah Kleinfeld
Yeah.
Dave Asprey
Based on how all the other omnibiotic stuff works, I would say there's a high likelihood. So that's something to pay attention to. Yeah, I, I didn't know about this. This is super cool. You guys are always coming out with cool stuff and, and it's funny that it's coming out of Europe and you're bringing it to the US because most companies, they're kind of wild west out here and then maybe they try to move into Europe. But in Europe, there's stronger standards for the science you have to do. So if it originates in Europe and then we bring it to the US There's a pretty good chance that it's solidly built. Okay. Caracol is what that's called.
Hannah Kleinfeld
Yeah, caracol. So caracol Gastro is the 1 gastro for your stomach. And then the original caracol is the. Just the pure papaya puree that actually works really well for people with constipation. So one of the big use cases in Europe, at least, is elderly people, because they suffer from this a lot, and women in pregnancy, because, you know, especially when you're pregnant, you don't want to take harsh medications, but you still have some of these digestive issues. So this is a really natural alternative.
Dave Asprey
As. As a guy, I have a hard time understanding constipation because it feels like with enough MCT oil and magnesium, it should be impossible.
Hannah Kleinfeld
That's. That's probably true. That is probably true. It's just. I don't know if maybe folks in their 80s and 90s who are dealing with this are aware of this as a good combination.
Dave Asprey
Anyone whose constipators ever tried that is going, dave, you're a jerk. Because that creates something called a depth charge, because you will build up enormous, uncomfortable pressure behind the constipation, and it will come out, but you will not like the experience, so don't do that. So a more gentler approach, like the caracol gastro that you're talking about or even just taking more soluble fiber would.
Hannah Kleinfeld
Be maybe a gentler way or maybe also just hydrating. Like, I think, you know, many people just forget to drink water and electrolytes and stay hydrated. And that is. I mean, the number one thing is just your. Your intestines also need the water to process your waste.
Dave Asprey
This is something really important. I only drink mineral water or water with salt or electrolytes in it only. And when people do body work on me, they're like, you have the youngest tissues I've ever seen. I'm like, yeah, that's because that's a proxy for hydration. And it's made such a difference in my cognitive function, just my overall health. There's also studies, though, showing that eating more sodium has an effect on your gut bacteria. Do you know anything about salt and electrolytes and gut bacteria?
Hannah Kleinfeld
Not in depth, but, you know, I think it's always. I would imagine it's how you're delivering the salt and the quality of the salt. You know, I mean, Salt is. Anything else we're putting into the body can be really clean and I'm sure it can also be contaminated. And, you know, just also making sure you have that right balance between sodium and the other electrolytes. And you know, I would never mix my omnibiotic and a bunch of salt water. You want to make sure it's kind of not in that suit. It doesn't hit you in that really concentrated way.
Dave Asprey
That's the important point. Since omnibiotics are going to soak up whatever it's in, I put mine in RO water.
Hannah Kleinfeld
Right, right.
Dave Asprey
And that means it's going to be fine. And then if I do have some mild salt water, the same as what's in my blood plasma is the goal for what I'm drinking, then it's not going to affect it. But if I added my electrolytes to the water and then I add my ammo omnibiotic, it's going to kill the antibiotic.
Hannah Kleinfeld
You don't want to do that.
Dave Asprey
Okay, that's an important point because I know a lot of people listening are doing what I'm talking about with sodium or with balanced electrolytes, things like element.
Hannah Kleinfeld
Yeah, I mean, same. You wouldn't want to mix omnibiotic in some sort of powder. Magnesium, you know, same thing. Because it's just, it's just too much for these living bacteria.
Dave Asprey
Right. And that's not to say you can't mix with water, chug it, and then take your magnesium, that's fine. It just has to be hydrated with, with basic water.
Hannah Kleinfeld
Okay, Exactly.
Dave Asprey
That's a really important thing. If you had absolute 100% control of someone's microbiome, how long do you think you could extend human life?
Hannah Kleinfeld
Ooh, by quite a bit, I would think. I think scientific number. I know, right? I don't know. What do you think, 20 years?
Dave Asprey
I'm guessing 40%.
Hannah Kleinfeld
40%. Okay. Yeah.
Dave Asprey
And I mean, I can give my reasons for it, but give your reasons first.
Hannah Kleinfeld
We'll have a little, I mean, you know, we touched on it earlier. The gut microbiome is just implicated in so many different things. 70 to 80% of our immune system originate in the gut. It supports our gut brain axis. It's. There's a gut liver axis. It's truly just, you know, and we've seen it, see it in mice too. In the mice studies, germ free mice, they live just a fraction of the, the duration that mice with a good gut microbiome live. And you also see in research a healthy gut Microbiome correlates with overall health and longevity. A dysbiotic inflamed, disrupted gut microbiome is linked to so many different health conditions, including cardiovascular disease, neurodegenerative diseases, even cancer. So, you know, I think that that in itself, if you can cut out some of these chronic illnesses, which are one of the many of the leading causes of death here in the US and worldwide, then you can go a long way. What's your reason?
Dave Asprey
We know, and I wrote about this in my longevity book, aging is death by a thousand cuts. There's no one cause of aging, and most of those cuts are inflammatory. And the number one cause of inflammation is immune activation. Right. There's also mitochondrial dysfunction, which is also tied in with all these things. Lipopolysaccharides from bad gut bacteria cross the gut barrier if it's not intact, and then they go in and they inhibit mitochondrial function. So if we had a gut that never leaked, it only had good guys growing in it, you'd have these manufacturing plants making all the beneficial postbiotics, like urolithin A, like spermidine.
Hannah Kleinfeld
Right.
Dave Asprey
Like butyrate propionic acid. Right. A lot of these are supplements that I've talked about on the show and written about, and probably a bunch of them we don't even understand yet. So you could control. You could also add some ones that make custom things, like there's a glutathione one. And so you could literally tailor the manufacture of longevity molecules in the gut and stop all the bad stuff, stop all the immune activation. That has to be a lot of what we could do for Aging. 40% is a guess, but I think it's bigger than most of us believe. So in the meantime, having a really healthy lining in the gut, I'm actually excited about your new product for that. And then having the appropriate mix of gut bacteria that make longevity compounds with making fewer toxins, that seems like a good strategy, at least to support your health, which is a boring goal. Like, of course you want to support your health, but I don't want to support my health till 86. I don't support my health till 180. Yeah, it just seems more interesting.
Hannah Kleinfeld
Right. Well, and I think you raise a good point there. You know, people don't just want to extend their lifespan. They want to do so while still feeling good. There's no use extending it by 20 years. And then just lying on the couch those 20 years, you want to still be active and energetic and that, you know, you can certainly achieve by making sure you keep inflammation low in your body, keep your immune system functioning properly, keep your gut brain axis working well, that's a pretty good foundation, I'd say.
Dave Asprey
And it's an easier foundation than going out and taking the latest longevity drug or something, but I'll do both just in case. Same Hannah, I appreciate you coming on the show and I ask anytime someone representing a brand comes on, give a meaningful discount to the audience. So you've offered a 20% discount, which is a pretty good chunk. That's omnibioticlife.com Dave yes, and thank you for that. And if you're listening to this and you're saying, well, Dave's promoting something, yeah, I like to promote science and things that work and tools for longevity. Look, if your gut's fine and everything is great in that aspect, spend your money on something else, right? The odds of you having a high functioning gut if you eat almost anything that you can buy at a restaurant are not that high. And like I said, I have three different boxes of the stuff downstairs and I guess four because you brought me a new product. So I'm going to talk about the things that work and the biohacks that may be worth it for you. I'm gonna talk about more of them than you're probably going to do because you are unique and you have your own goals and you have your own current state. So maybe you took antibiotics and you're like, oh, this month I'm gonna do the a B10 and maybe this isn't a priority. I'm working on something else entirely. Then this isn't the thing for you. But you know how it works and you know what it is and you can save some money. I want you to go to Omnibiotic Life and use it if it's good for you or you think it might be, with my blessing.
