Welcome back Kik Brains. I am your brain coach, your host, Jim Kwik. Today's conversation is about something most people don't think about until they start feeling the effects. And I think most of our listeners here, wherever you are in the world, you could identify and relate to these things like the hidden stress that modern life places on your brain and your body. My guests today are David Roberts and Dr. John Gilday, Co founders of Mara Labs. And David has an interesting story, has been much of his career working at the intersection of public health, science and practical wellness with a deep focus on helping people reduce the toxic burden and, and support your body's natural ability to, to heal. Dr. Gilday is a molecular biologist with decades of research experience in cellular resilience, gene expression, oxidative stress and your body's natural defense systems. And together on this conversation they bring both sides, both the personal and the scientific sides of this conversation. What happens when modern life overwhelms the body and obviously your brain's part of your body and how we can better support the systems that protect, you know, your, your brain, your energy, your long term health, cognitive and otherwise. And today I'm excited because we're going to be talking about what is really draining your cognitive energy from, you know, how, how modern toxins and inflammation can affect your brain and what most people misunderstand about detox and how to support your body's built in defense system. And it's very simple everyday ways. So David, Dr. Gilday, welcome to the show.
B
Thanks so much for having us. Great to be here.
C
Yeah, appreciate it.
A
So I get to bump in to you at various events that I get to speak at. Wellness Longevity Biohacking transparently. I, I've been, I mentioned this in the beginning. I've been a customer of Mara Labs for years and so this is kind of fortuitous. I've always wanted to go deeper in this subject and our, our audience is very interested in this topic. So maybe we can start with you David on the. Let's with the more, more personal sides of this. What led you to this work and why, why did it become so important to you?
B
Yeah, so again, thanks for having us. So, yeah, my wife, my late wife Mara, was diagnosed with breast cancer back in 2012. And she was a nurse and knew enough about chemotherapy that she didn't want to do that, but wanted to look into natural ways to fight the cancer. And so kind of chemotherapeutically and so looked at a variety of different research, came upon sulforaphane, which is a good molecule from broccoli, pretty quickly. And we ended up growing, with John's help, her cancer cells in our lab and put 60 different supplements on the them to see what specifically killed her type of cancer. And the sulforaphane from broccoli was number three and directly killing her cancer cells. And so when I went out to buy it, though, I couldn't find any supplements that had sulforaphane. They all had the precursor molecule called glucoraphan. And that's because it's. The sulforaphane is a not stable, but gluten, the precursor molecule, is stable. So if you have a head of broccoli, you start chewing it, it has glucoraphanin, you break the cell wall and it releases an enzyme that converts that into sulforaphane. You swallow it and get the benefit. But if you try to. If you try to harness it like in a capsule or something like that, it degrades within hours to days. And so. And so we ended up growing like a lot of broccoli sprouts. And so for years we did that and know it, it's kind of fun, but then, you know, it's hard to travel with them. And. And then in the summertimes especially, they can mold. And so I think I was asked just at lunch with John one day, and I was kind of moaning about losing a crop or something. And it's like, it would be really nice to have a stable form of this so we. I wouldn't have to grow the broccoli sprouts. And so I don't know if that was the impetus, but like two years later, literally over lunch again, he kind of matter of fact was like, yeah, I stabilized sulforaphane. And we're like, what? And. And so we send it up for testing. And sure enough, he had. And so we were actually with a different supplement company at the time, so weren't going to do anything with it. But more I was like, we have to get this out because it's such a game changer for people's health. And so she started raising the seed money for the company. Unfortunately, she took a Turn for the worse. And that was 2017. And, and, and just pretty quickly died. And so after she died, we were like, we're going to do this. And so I left the supplement company I was with, started MAR Labs, and, And then got the, you know, the product out on shelves within, like, six months. So it was pretty quick, pretty quick turnaround. And so, yeah, we've been going at it since 2018.
A
It's, you know, I always admire businesses that, you know, that they take something that's very personal and they help, you know, they learn something. There's a gift that came out of it, some kind of learning and then. And then share that at scale. You know, certainly it's kind of, kind of our story also. Also as well. Dr. Gilday, maybe we could talk about on the science side, what pulled you into studying initially the. The body's defense systems? You know, was there a moment when you realized that this was an area that you wanted to dedicate your work and your life to?
C
Yes, I would say that the NRF2 pathway, that's the transcription factor that sulforaphane is famous for, been aware, you know, very aware of it since the 90s when that was discovered at Hopkins. We both went to Hopkins, so we kind of got educated in that atmosphere. We keep hearing about, you know, the Chemo Prevention center. And so I've always been interested in it. And, and if you study anything related to chronic disease, then, you know, inflammation and toxins and the interface of that are always central. And then I have an interest in epigenetics as well. So that noise that happens from, you know, the, the forgetting of the cell of, of what it is, the dedifferentiated state is, Is kind of central to the way I think of how chronic disease happens. And I think it aligns nicely with, with, you know, such a. Such a complex organ as the brain. And even though I studied the kidney, I, I studied dopamine in the kidney, and. But I was always looking at brains. So even though the brain is kind of uncomprehensible to me, I, I try all the time. And, and so NRF2, being in the center of so many pathways that are critically important to the differentiated state, all different cell types, specific functions, energy detox is just very central to, just the way I think about cells and health in general.
A
Oh, I want to go into the MO in a moment, talk about microplastics, because people are hearing about it all the time, especially the past few years. But before we do, when we're surveying our community A lot of people have challenges with things like, like brain fog, you know, and from, from your research or understanding, you know, what could be happening inside the brain when, when people, when that make people feel that way. Are there some, some considerations that you're looking at?
C
Yeah, I mean, I, I certainly have a couple of pathways in mind when I hear brain fog. Energetics for sure, is part of it, so mitochondrial function. And then I would say this, this entire clear network, it's a set of genes that are turned on by tfeb1 that clear out all the junk. And Then of course, NRF2 on top of it again, is, is the toxins accumulating in your brain would, would be a big taxing to all of those systems messing up your, your clogging up your detox system, messing with energetics. And then, yeah, just general differentiation state. I think a lot of people don't realize that when you have reactive oxygen species and they cause double stranded breaks, it distracts the machinery in the cell from it remembering who it is. So it happens during development. You get, you know, locked into. This is the cell that I am and this is how I have to remain for the rest of my life. But it's slowly forgotten by that distraction. And so I think the combination of, of lack of detox and energetics are kind of the central feature of, of brain fog. And surprising number of, of people that, that call in say that is one of the main things that they continue to take the product for. What.
A
What about inflammation?
C
Wow.
B
Yeah.
A
Like, you know, and, and its role, you know, if, if, if everyone understood one truth, let's say, about inflammation, you know, what do you wish that would be and how do you think it could change, you know, this understanding, change people's daily lives?
B
I mean, I, I think we both have a take on that. I mean, I think the important thing to know about inflammation, that there's really two types. One is good. There's a good type of inflammation. So if you get a cut on your hand, let's say your, your immune system reacts to that and it release. It's a type of acute inflammation that brings healing. But then there's the, the more chronic inflammation, especially in your gut, that leads to. So I look at it, the difference is sort of acute inflammation is like throwing gas on a fire. It's, it's quick and then it burns out. And, but the chronic inflammation is slow. It's like a, a rug that's smoldering over time. And that, that chronic inflammation can lead to really bad stuff. It can lead to intolerances, short term allergies and then autoimmune long term. And so the, the thing to know about our products is, you know, especially the broccoli one we were talking about is that can cut the pro inflammatory markers quickly. So like 30% in 24 hours. And so people take, take it and notice a difference overnight. Really?
C
Yeah. We were excited when we did our first study. We knew that in the literature it said that there was anti inflammatory activity and we knew the mechanism. It's a direct conjugation of I kappa kappa beta, part of an F kappa B system. And so we found that IL6, a really good marker of, of smoldering inflammation went down 30% in 24 hours with just our normal dose of, of our supplement. So we knew we're on the right track for, for that particular metric. And brain specifically sulforaphane has no problem getting into the brain which most of the other anti inflammatories do.
A
Yeah, yeah. Even dating back 30 years I've been talking about broccoli as one of my top 10 brain brain foods. And then you know, about 15 years ago I started talking about sprouting. And there's a science, but there's an art to it also as well.
B
Yes.
A
For those who've ever attempted to sprout your own, your own broccoli, let's talk about you both dedicated your careers to studying sulforaphane. So what is it and why is it so important?
B
Yeah, and so again it's the good molecule that is derived from broccoli. So basically like I mentioned before, the precursor molecule called glucoraphanin, which is basically an all broccoli supplements except for two hours and one out of France called prostaphane. They and the reason for that is that the glucoraphane is stable. And so with our supplement though, we extract both the sulforaphane and make that stabilize. But there are seven other isothiocyanides cousin molecules to the sulforaphane that we extract as well. And so if you read the all the literature that comes out of Hopkins and their chemo productive center there, they, they couldn't stabilize it, but they, they would have, they had a, a broccoli sprout growing center and would make these broccoli sprout beverages to give all of the people who did the studies. And so they're extracting all of the molecules, not just sulforaphane. And so we also go out and add one molecule from watercress called phenethyl isothyanate, which is the name is not important. But what is important is that when you put that together with sulforaphane, it's actually synergistic. And so when we're talking about turning on NRF2 which is why you take sulforaphane, you basically it's not additive. If it's one plus one equals two, it's, it's synergistic. One plus one equals five. So there's a five times effect turning on that pathway. So yeah, I mean it's sulforaphane that has 39 pro health mechanisms in the literature and actually 40 now that we, someone did research on microplastics but, and releasing microplastics for excretion. But basically brain health. So it turns on bdnf. So brain derived nootropic factor which as you know is at the center of brain health, protecting existing neurons, helping grow new neurons. Inflammation, which we've already talked about. And then also this detox. So it's the best natural molecule turning on the phase two detox. But it works in all three phases. So that's, it's a, it's one of the only things I know of that that can work in all three phases of detox.
A
And when we're talking about detox, a lot of people think cleansing or water or juice fasting, maybe something even more extreme the way you look at it. And also really in relation to social forfeit, you know what do, what do you think what is missing and what are people getting wrong about the detox process?
C
Yeah, at least the way I hear detox being talked about. It's, it's not generally through the, the actual detox pathway that your body uses to get rid of toxins. Toxins are usually toxins because they accumulate in your body. They're generally hydrophobic. And so just a general understanding of sulforaphane turns on this transcription factor that turns on a whole bunch of genes and it's those are made to both increase the amount of glutathione and then go through the three phases of detoxification. The first phase is making it water soluble. And so that takes a toxin that's locked in your system, makes it water soluble, that sometimes makes it worse at first. But so you get phase one, then phase two is three different aspects of conjugation. You can get gst, glutathione conjugation or sulfation or glucuronidation, those are phase two and then phase three is how you get those conjugated compounds out of your body. And so that's how you normally detoxify. And sulforaphane does all three phases and is why you can actually detox without getting like a keto flu or not keto flu, the detox flu, the Herxheimer's, the, A lot of the side effects that people will get if they're just mobilizing toxins.
B
Yeah, a lot of the, those, like those cleanses you're talking about are really good at phase one, but then it backs up and so you feel sick because you have all these toxins released. And so sulforaphane actually, it, it slows down the phase one, but it works in phase one and then it speeds up phase two. And so you actually can clear really nicely and not have that, that sickness that you sometimes feel. And I mean, it works. Yeah, it works amazingly well. I, I mean, I, I joke, but it's also true. I always take bottles to holiday parties and, and people expect it now so that, you know, if they have a little alcohol, they won't feel bad in the morning. So it's, it's one of the, it does work.
A
Yeah.
C
The enzyme system for alcohol is aldehyde dehydrogenase. And so sulforaphane stimulates that. I just know about that because it was highlighted recently at UVA as a longevity study. And so it's interesting that sulforaphane actually induces that.
A
It's a great supplement to have on hand for all occasions, for sure. Let's talk about, we're having a conversation before we started about microplastics. They're getting a lot of attention now. You know, I, I've seen everything, you know, from there could be a, you know, a spoonful of plast of those microplastics in our brain to, you know, we're exposed, ingesting in some kind of form into our body, like a credit card a week or something like that. But even if it was like a fraction of that, what are microplastics when, when people are hearing about them and what should people understand about them, you know, so that they feel enabled. Right. Because it could be very scary. Like when you're thinking about the synthetic fibers that are on, in your carpets or in your clothing or in your furniture or, you know, all these, you know, where we're exposed or plastic bottles. What are microplastics and why should we be concerned?
B
Yeah, I mean, so the easiest way to think about them is their micron or even nano size, so about the diameter of human hair. Size pieces of plastic or smaller. And so those get leached from different plastic containers, like water bottles and. Or in the air, like you mentioned. In fact, most of our microplastic exposure comes from indoor air. And so that could be synthetic clothing. My couch has foam. And so if I. If you bang it, you know, you. You'll see some dust. Yeah. The mattresses. Most of them. A lot of them. And so, you know, the lint from your dryer. I can't. I can't take lint out of dryer anymore without holding my breath. Because it's. Because it's proportioned to them.
A
Yeah, all of that.
B
Yeah, that's.
A
That, that comes up.
B
That's microplastic, mostly. And unless you have all natural fibers that you're drying, which must be one.
A
Cotton wool.
B
Yeah, exactly. And so. And so basically what happens is it gets in your body and it gets engulfed in these things called lysosomes, which are these vesicles inside the cell that are like the digestive. They're sort of the garbage disposals, and they have digestive enzymes they secrete to try to digest the various particles, which usually works if it's like a microbe or protein, something like that. But microplastics can't be digested, so they get backed up in these lysosomes, much like food gets backed up and clogs the kitchen sink. And so it doesn't work properly. And so. And so basically, it's an issue because the microplastics are porous. They can have, I read recently, up to 10,000 different toxins in them, including BPA, which is known to be an endocrine disruptor. And. And it basically mimics estrogen. And so that can lead to all sorts of issues both in men and women. The. The Netflix documentary that came out in March talked about infertility, highlighted infertility and microplastics. Well, that's because it can, you know, cause irregular menstruation in women. It can cause early puberty in girls, can cause low testosterone and low sperm count, as well as quality in men. And so, I mean, just. Just on the endocrine side, that's a big. It's a huge issue. But then there's other, you know, other things they can do too cardiovascularly and on and on. And so, yeah, it's. It's a. It's a big deal. But I mean, like we said there, because most of our exposure comes from air, one of the things that I mentioned is to people is the best thing you can do is Have a HEPA filter in the room you sleep in. And so that can mitigate quite a bit of your, your exposure.
A
Yeah, reduce the, all the synthetic fibers from furniture. And we've had this discussion with, you know, various mattress companies or, and you know, talking about air scraping also as well, that we. 95% of our time indoors, you know, which, which could also be a challenge. So, so the, the, the, the, the downstream effects your, your endocrine system, your, your, your hormones, cardiovascular, your nervous system. I mean, so if you're having, sitting with like one of our listeners right now and you're having a meal and they wanted to ask you a question, like something because I'm sure, um, you know, how, if the question was something like how would one support their body's natural defense, you know, systems today? What are a few simple things you would, you would recommend?
C
Yeah, I like, I like the general idea actually framed like epidemiology, epidemiologist, is reduce your toxic burden first. And so what are the, what are the big things that you do? Like if you're vacuuming, use a vacuum with a HEPA filter. And then the food that you eat, try and source it as best you can so that it, you know, has as little plastic in contact with your food before you eat it. Your water, the best source of water, at least from our research, is reverse osmosis. Water has no microplastics. So after you reduce the, the intake, then the next thing to look at is your barriers. So when you breathe it in, the majority of the microplastic gets caught by your mucus layer and is rhythmically moved backwards up through your esophagus and swallowed. So basically all, all of the biggest burden of your microplastics are in your alimentary canal. And then making sure that that barrier is intact will keep it from being absorbed in general. And so we always say. You don't listen to us. It's. The review articles say that NRF2 is the center of tight junctions. So you keep tight junctions along your entire digestive tract. You're going to keep them, most of them, from being absorbed. And then after, after that the, they're small enough, there are cells in your body that just run around and consume things. And those, your macrophage or your microglia in your brain. So that's the other place beside the lining of your intestine in your lungs is wherever macrophage accumulate, they have microplastics in it.
A
Now there's no, there's no test. Is there a test for microplastics yeah.
C
Brian Johnson's has a, has a microplastic test from blood. And then so what we were interested in was this researcher who is a lysosome researcher, John Budvig is, did a test on himself and took our product and tested by that facility and got the highest microplastic score ever done by that company. So it mobilizes microplastics and we think the mechanism is by, by this, it's called lysosomal dumping. So it fuses with the cell surface and dumps the, the contents of inside the lysosome into the extracellular fluid. And so that's the first step and we're very excited that you know we could show. He repeated that study with us this year and so that's reproduced now and and then I continued the study with showing where is it removed. And so we measured sweat, feces and urine. And by far the most the biggest signal of where it's increased to get it out of the body is in feces. And so we showed just recently that that that is the way that the majority of the microplastics are gotten rid of. And so we did an induced removal of microplastics with a large increase in feces. So that's sort of the framing that I generally think of as you know, reduce the amount that you take in and then, and then have a known mechanism of way of getting out and be consist consistent.
A
So so in your research and just in your experience what, what are the top foods or your go to supplements that you would recommend our listeners should want to, who would want to support their detox inflammation? You know, balance brain cognitive health.
B
Yeah, I mean I think the ones when we have a seven day microplastics detox protocol we have the broccoli first and foremost. If you're going to do one that would be the best because it just covers so much and it's like John said, it gets to the brain and so it helps with neuroinflammation inflammation. And then second would be resveratrol. So if you think about the, the kitchen sink analogy where the sulforaphane unclogs the sink but the resveratrol actually widens the plumbing so it allows more of these microplastics to get out. And then we, you know, also flush niacin is can, can actually increase the, the vasculature and help with reduction as well. And then most recently the fenugreek. We've read that fenugreek actually as John said, most of Those microplastics stay in your gut and get excreted. But the fenugreek can actually bind those in the gut and help with that excretion. So we're not talking about what the microplastics that are inside of you, but the ones that are in your, in your gut. So this would be, I mean, but inflammation wise the curcumin is the best natural molecule at downregulating the NF kappa P, which is sort of the holy grail that the pharmaceutical companies go after when they're trying to get a, A anti inflammatory on to market. And so that is ours is very bioavailable. Can't say it's the most bioavailable else we get sued. But it's very bioavailable and you, you can feel the difference.
A
And it's different than just taking like turmeric, right?
B
It is if like eating turmeric.
A
Yeah.
B
If you, it's about what is it about 5% of turmeric has, is curcumin. And so it's the good molecule. And so they, you extract the curcumin from the turmeric root and then you get, you know, curcumin but also cousin molecules to curcumin and then basically, but it's basically less than 1% bioavailable and so not much gets through the gut barrier. And so if you're, if you're taking it for your gut inflammation, it's great. But if you're taking it because you have, you know, knee pain or joint pain, it's not going to do the, do the trick. And so, so as I said like you know, it the, if you're talking about brain, the best is broccoli because it's, it travels, it's, it travels so easily through, through the barriers. But curcumin is also very good.
A
Yeah. And I don't know a human being that could I, I started just recently took, started taking your Kirk elite also. I don't know how many, you know, like how many people could really eat that much turmeric and broccoli. You know, and then certainly if they're traveling, you know, also with, with everything else. So I mentioned I was, I started taking broccoli years ago. Yeah. Probably early when you, when you initially started because I, I knew that the power of it but I couldn't get it easily into my diet. Right. Or as much, you know, for that inconvenience is very important for me in order to be have, be compliant. Right. You want to be able to reduce that friction. But you know, I just can't go without it because of the change in mental clarity. You know, I just feel lighter, less inflamed. Where now we did something really special for our listeners also. So I just want to mention that for broccoli, this, this product here, I want to thank you for offering a special discount to all our listeners. You know, as a, to be, as a consistent listener to our show. If you go to what is it, it's mara-labs.com and if you put forward slash quick, that's Kwik and you use Kwik at checkout, you get, you get a special discount. Just as a thank you for being a listener and you know, joining this episode, we'll put all that as we always do in the show notes@jimquik.com forward/notes. For those who are not familiar yet with Marlabs, what, what does broccoli do specifically?
B
Yeah, so as I mentioned it, it turns on the BDNF production. So brain drive, no tripa factor, which
A
is like fertilizer for that for your brain, for, especially for neuroplasticity.
B
Exactly. And, and probably about a quarter of the people who take it will have vivid dreams. I don't know if that happened to you. It's great for inflammation. So as we mentioned earlier in the program, it turns reduces pro inflammatory markers 30% in 24 hours. That's two of those capsules, two broccoli and those two capsules, it's 10 milligrams of sulforaphane, this equivalent of about five pounds mature broccoli. And then it's really great at detoxification. So it works in all three phases of detox. But it's the best natural molecule at phase two detox. And separately from that and more, most recently it's been shown to mobilize microplastics for excretion, primarily excretion through stool. So it's, it's the only thing that's been shown to do anything to get microplastics out so far.
A
And what's the recommended protocol for it?
B
Because it's pretty powerful. We recommend people start off with one capsule and then, and then if that works for you and you noticing the benefits to start off with two, you know, we offer 100 day money back guarantee because we want people to not feel burdened if it doesn't work for them. Everybody's different and some people will notice that it doesn't and that's okay.
A
And they take it in. Doesn't matter. The Time of day. Food, no food. What do you recommend?
B
We recommend taking it with food because it can be hard, it is potent, it can be hard on your stomach and cause a little nausea. So if you drink some milk or eat some food with it that you bypass that as you kind of take it longer. You don't have to do that.
A
It's part of my staple. I mean this is kind of one of my non negotiables. So I want to thank you David, Dr. Gilday for giving us your, your valuable research and your insights today. For those people who are listening and they want to go further into the topic or where can they connect or, or be able to find out more about your company.
B
Yeah, so we're at marai-labs.com we have a blog. You can sign up for our newsletter. We send out information regularly but we're also on social media at the Mara Labs, Instagram and Facebook, the M A R A Labs. And so as you mentioned, we do have a 25% off sale for the first, this first week after this is launched.
A
Well everyone, there you have it. Today's conversation. Let it be a reminder that, that brain health doesn't happen in, in isolation. You know, your brain is connected to your rest of your gut, to your immune system, to your inflammation levels, your environment, the daily choices that you make, you know, even we're talking about nutrition, you know, what, what you ingest matters especially for your gray matter, you know, and it's nice to have some hope and some help especially when it comes to things like microplastics where you know, we could reduce, you know, we can only control our environment to a, you know, to a certain degree to mitigate the effects. But it's nice, we could do something proactive, you know, and also know that all the other benefits with inflammation, the, the brain derived neurotropic factors and just, it's a reminder that while modern life exposes us to all these, you know, more stressors than ever, as I mentioned from previous generations, we're not, we're not powerless, you know that. And this is really what it's about. It's giving people reminding of their own agency, you know, that we have these built in systems that are very intelligent, they're designed to protect and you know, repair, restore, you know, harmony and balance. But the key is really learning how to support these systems, you know, because what you nourish, you know, flourishes. Right? You know, while we're reducing the unnecessary, you know, toxic exposure, we're supporting our gut, we're paying attention to what your brain and your body is trying to tell you. So again, if you want to learn more about Mara Labs and the product that I mentioned that I've been taking for years as a customer, paid for it myself, you know, my family also as well, we have, we turn a lot of clients onto it. Mara-Labs.com forward slash, quick. That's Kwik. And check out Use Kwik for a very generous discount. And if this episode gave you a new way to think about your brain, your body, I would love for people to share their biggest takeaway and post it online. You could tag Mara Labs. You could tag us on there also as well. I always reshare some of those. Since you tag us, we get to see it. Until next time, this is your praying coach, Jim Kwik. And be limitless.
Episode: How Microplastics and Inflammation Affect Your Brain
Date: May 25, 2026
Guests: David Roberts & Dr. John Gilday (Co-founders, Mara Labs)
This episode explores the profound but often overlooked impact of environmental toxins—particularly microplastics—and inflammation on brain health. Host Jim Kwik sits down with David Roberts and Dr. John Gilday of Mara Labs to discuss the science behind modern cognitive drains, the misunderstood mechanisms of detoxification, the role of sulforaphane (a compound found in broccoli), and clear, practical steps listeners can take to defend and rejuvenate their mental performance.
David: “I couldn't find any supplements that had sulforaphane. They all had the precursor molecule…so we ended up growing a lot of broccoli sprouts.” (04:16)
Dr. Gilday: “If you study anything related to chronic disease, then inflammation and toxins and the interface of that are always central.” (06:53)
Dr. Gilday: “Lack of detox and energetics are kind of the central feature of brain fog.” (09:37)
David: “Acute inflammation is like throwing gas on a fire…chronic is a slow, smoldering rug.” (10:53)
Dr. Gilday: “Sulforaphane has no problem getting into the brain—which most anti-inflammatories can’t do.” (12:14)
David: "It's one of the only things I know of that can work in all three phases of detox." (14:30)
David: “Sulforaphane slows down Phase One but speeds up Phase Two…so you can clear nicely and not have that sickness.” (17:05)
David: “Most of our microplastic exposure comes from indoor air…my couch has foam…lint from your dryer—that's microplastic, mostly.” (19:40, 20:13)
Dr. Gilday: “We measured sweat, feces, and urine: the biggest signal…is in feces. That's where the majority of the microplastics are gotten rid of.” (26:19)
David: “Curcumin is the best natural molecule at downregulating NF kappa B...if you're talking about brain, the best is broccoli.” (28:50, 29:25)
“Modern toxins and inflammation can affect your brain—and what most people misunderstand about detox and how to support your body's built-in defense system in very simple, everyday ways.” – Jim Kwik (01:05)
“Chronic inflammation is like a rug that's smoldering over time…that can lead to autoimmune and other bad stuff.” – David Roberts (10:57)
"Sulforaphane turns on BDNF, which...helps grow new neurons." – David Roberts (14:53)
“The best thing you can do is have a HEPA filter in the room you sleep in.” – David Roberts (21:52)
“While modern life exposes us to more stressors than ever…we're not powerless. We have these built-in systems, they're intelligent, they're designed to protect and repair.” – Jim Kwik (34:22)
