Welcome to office Hours. This is our dedicated one on one space to go deeper, get clear, and explore what truly moves the needle for your health. I'm Dr. Mark Hyman and each week we're going to pull back the curtain and share the insights, the research, the lessons that don't always make it into our conversations with guests. Because at the end of the day, you are the CEO of your own health and for many of you, your family's health, too. And you might not feel it all the time, but you have far more power and agency than you realize. I'm glad you're here. This episode is brought to you by Function Health, empowering you to live 100 healthy years with over 160 lab tests at just $365 a year.

They build muscle, they burn fat, improve sleep, heal your gut, boost your brain. But what are they? And are they the future of medicine or just another biohacking fad? Well, these tiny molecules control almost everything in your body. So what happens when we start manipulating them? Well, today we're going to cover what peptides actually are, how they work in the body and the most common types that people are talking about. We're also going to talk about who might benefit from them and who should be a little cautious, and also what functional medicine says about them. Peptides aren't magic. They're signaling molecules. And understanding signaling is understanding health. So what is a peptide? Peptides are being called the future of medicine. If you've been anywhere near social media, wellness clinics, or biohacking podcasts, you heard the claims and. And you're probably confused. Peptides can help you lose fat without losing muscle. It can heal injuries faster, it can help you sleep deeper. It can improve your metabolism, it can slow aging, it can extend your lifespan. It sounds almost too good to be true. And here's the thing. Peptides aren't some fringe experiment. Your body runs on peptides. Insulin. That's a peptide. GLP1, also a peptide. Growth hormone signaling, also peptide. These tiny chains of amino acids are essentially text messages between your cells. They tell your body when to build, when to burn, when to repair, when to rest. So when we start introducing synthetic or therapeutic peptides into our system, we're not adding something foreign, we're just altering the messaging. And that's powerful. But powerful doesn't always mean appropriate, because the Real question isn't do peptides work? The real question is in what context and for whom and at what cost? Are peptides enhancing healthy biology or are they compensating for a broken foundation? Today I'm going to give you a crash course. Peptides 101. What they actually are, what the most common ones do, who's going to benefit, who should be cautious, and how to think about them from a functional medicine perspective. Because in my world we don't chase trends. We restore healthy signaling. And that requires understanding the system first. Your whole body system. Why are they everywhere? Part of its timing. People are frustrated with conventional medicine. They're tired of medications that suppress symptoms without addressing the root causes, like antacids for reflux or heartburn, statins for cholesterol, antidepressants for mood. We built a system that often manages disease instead of restoring health. But peptides feel a little different. They're often described as more natural because your body already makes them. They're targeted, designed to influence specific signaling pathways instead of blanking the whole system. And they promise regeneration instead of symptom suppression. Instead of blocking inflammation, they claim to enhance repair. Instead of forcing weight loss, they claim to optimize metabolism. It's really appealing. And add to that the anti aging movement, performance culture and the biohacking world and you got a perfect storm. People want to feel better, they want to heal faster, they want to age slower, they want to perform at a higher level. And peptides sit right at the intersection of medicine and health optimization. But here's a reality check. Many peptides being marketed Teddy are not FDA approved. Some are compounded, some are sold as research chemicals. Be careful with that. Quality control can vary widely depending on where you get them from. And for many of these compounds, long term safety data isn't really available yet. Cause we just haven't studied them. And that doesn't mean they're inherently dangerous. But it does mean we need to be careful and be discerning. Just because something is cutting edge doesn't mean it's appropriate for everybody. So just because it's trending doesn't mean it's foundational. In functional medicine, we always ask, what's the biological context? Is the foundation of your health solid and is this intervention really necessary? Well, peptides may represent the future of certain therapies, but they're not a substitute for the basics. Meaning what you eat, how you move, how you sleep, how you deal with stress, toxic load in your body and your life. All those things matter. So let's talk about the most common peptides, obviously the most common peptide being used and talked about today are the GLP1 drugs or GIP, which is another variation of the GLP1 peptides. GLP1 stands for glucagon. Like peptide 1, big mouthful, doesn't matter. It's a hormone that your body naturally produces in your gut after you eat. And what is its job? Makes you feel full, it slows the emptying of your stomach, it stabilizes blood sugar, it helps improve how insulin works in your body and makes you more insulin sensitive. In other words, it helps regulate your appetite and your metabolism. Medications like semaglutide, tirzepatide, things like Mounjaro, Ozempic, these are synthetic versions or enhancers of this natural peptide system. And, and they really amplify the system and the results can be dramatic. Weight loss, lower a 1c or your average blood sugar, lower risk for cardiovascular disease, improved metabolic markers, all that sounds great. And for some with severe obesity, type 2 diabetes or significant metabolic dysfunction, these peptides can be life changing. But here's the nuance. These medications don't build muscle and they don't automatically fix poor diet. If someone loses weight rapidly when without adequate protein and strength training, they're gonna lose a lot of lean muscle along with the fat. And that is not a small detail. Muscle is a key organ of longevity. It's your metabolic engine. And losing it while you lose weight can actually undermine your long term health. So it's not good if you lose muscle along with the fat. You don't wanna do that. Here's another question we don't talk about what happens when you stop. If your lifestyle hasn't changed and you stop these drugs, your biology just goes back to where it was. You gain the weight back. So from a functional medicine persp, the GLP1 peptides are powerful tools, but they're tools inside a much bigger system of creating health. We always ask, is this supporting the foundation of your health or is it compensating for something that's missing? Because the real goal isn't short term weight loss, it's durable metabolic resilience, meaning you can eat in a variety of ways that aren't super restricted if you become metabolically resilient. For example, if I exercise every day and I heat up a low sugar starch diet and, and I have some dessert, it ain't gonna kill me. But if I'm diabetic and my blood sugar's all over the place and my insulin's really high, it can be Quite serious. So you have to get metabolically resilient means you can have more freedom in your life. That's the goal. Every spring we're cleaning and taking inventory of our closets and our budgets. But where's the expert organizer for your health? Because right now, nutrients could be depleting your body and inflammation could be building up. Toxins could be accumulating. Unless you test, you have no idea what's actually going on. Many people don't. They wait until symptoms show up or something gets flagged way too late. This is the reason function exists, to help you take a deeper look, to see what's working, what's depleted and what needs attention. You have access to over 160 lab tests for your heart, your hormones, for nutrients, toxins, metabolism, and lots more. For just $365 a year, that's a dollar a day, you can get your data and reset your life@functionhealth.com now let's move into another category that gets a lot of attention. The growth and repair peptides. Now these are the ones you hear about in the athletic circles, the biohacking communities, and increasingly in longevity clinics. Things include BPC157, which can help with tissue repair, thymosin beta 4, which also helps immune function, and tissue repair CJC1295 or immunity ipamorelin. These compounds are marketed for faster injury recovery, for improved muscle growth, for gut repair, even anti aging. So what's the appeal? Well, they're designed to stimulate repair pathways in the body. Now some may promote angiogenesis, which is the growth of new blood vessels, which can be good, but also that may increase cancer risk. We just don't have enough data yet. Some may enhance collagen production, which is good, that helps repair tissues. Some can stimulate growth hormone release, which helps with tissue repair. It's your repair hormones. And some help with tissue regeneration. So in theory, they enhance your body's natural healing signals. And in certain contexts, that's great. If someone's recovering from a tendon injury, if someone has impaired healing capacity, if there's muscle loss associated with aging, the idea of enhancing repair pathways makes sense. But here's where we need maturity in the conversation. Most of the strong data for these peptides comes from animal studies. Human trials are often small or limited. We're still doing them. We need more data. And anytime we stimulate growth pathways, we need to think carefully. Growth is powerful, but growth isn't always selective. Right? If someone has active cancer, if they have a hormone sensitive tumor or higher cancer risk, Stimulating these growth pathways may not be appropriate. That doesn't mean these peptides are dangerous across the board, it just means context matters. In functional medicine, we ask, is this person deficient in repair capacity or are they trying to accelerate something that already has the right inputs? But here's the truth. Most people just skip over. You don't need a growth peptide if you're chronically sleep deprived. You don't need a repair peptide if you're not eating adequate protein. You don't need a regenerative intervention if inflammation is still uncontrolled from various triggers in your body. Your biology is layered. Growth peptides may support healing, but they can override a stressed, inflamed and a nutrient depleted system. What's causing the damage? We're treating the downstream effect and not the upstream driver of the problem, which is always the goal in functional medicine. So yes, growth and repair peptides are intriguing, but they're not shortcuts, they're amplifiers. And amplifiers only work properly when the signal underneath them is healthy. So you gotta get your foundation right. Probably generates the most curiosity. Longevity and cellular peptides. And these peptides you'll hear about in biohacking circles, you'll hear about them in anti aging clinics, and you'll also probably hear about them at longevity conferen differences. There are things like thymosin alpha 1, mot C, epitalon, and they're often associated with mitochondrial health, with immune modulation, telomere support, and even lifespan extension. And this is where things get interesting, because aging isn't just about wrinkles or slowing metabolism. Aging is fundamentally about signaling, how well your cells communicate, repair, and how they maintain themselves over time. Take mot C for example. It's a mitochondrial derived peptide. Mitochondria are your cellular energy factories. They determine how well you produce energy, how resilient you are to stress, and how to efficiently you metabolize fuel. Now, in animal studies, mod C appears to improve metabolic function, even extend lifespan. Or maybe you're hearing about Thymosin Alpha 1, which plays a role in immune modulation. It's being studied in cancer, in infections, and in immune resilience. That's fascinating because immune aging is a major driver of chronic disease. And then there's epitalon, which is often discussed in the context of telomeres, the protective caps on your chromosomes that shorten as you age. Now, some early research suggests that it may influence telomerase activity. And that's provocative, but still highly experimental. Most of the research on these longevity peptides is preliminary. A lot of it is animal data, so some of it's early stage human data, very little of it is long term, large scale randomized controlled trials. So while the mechanisms are compelling and it's stuff your body already makes and uses all the time, and I find them fascinating, we have to balance curiosity with caution. And from a functional medicine perspective, we ask a different question. Before we try to enhance mitochondrial signaling with a peptide, have we optimized the basics that naturally support mitochondria because we know what strengthens mitochondrial function? For example, strength training, aerobic conditioning, intermittent metabolic stress like fasting, high quality protein, phytochemically rich plants, adequate sleep, controlling your insulin, and many other things. All these interventions have decades of evidence. Longevity peptides may one day play a significant role in precision medicine. But today they're adjuncts, they're not replacements. And you can't out peptide a bad lifestyle if your cellular environment is inflamed, if you're insulin resistant, if you're sleep deprived, if you're nutrient deficient, no longevity peptide's gonna override that terrain. But in the right context, with a healthy foundation. While these compounds may represent the next frontier in regenerative medicine, we just need more data, more discernment and more personalization before we treat them as mainstream solutions for everybody. They may be appropriate for a few people, people with severe metabolic disease like diabetes, people with obesity and complications from that, people who have injury and need to recover from that under supervision if there are specific hormone deficiencies, but they're not a substitute for adequate sleep, they're not a replacement for strength training, they're not a shortcut for eating a poor diet. Biology rewards consistency, not so much shortcuts. So who should be cautious about peptides? Well, people who have cancer or have had cancer, autoimmune diseases, people with autoimmune diseases, people with a hormone sensitive condition, people seeking cosmetic use only. Anyone buying from unregulated sources, be careful with that. And many peptides are compounded or sold as research chemicals, so be careful with those. And quality matters. Purity matters a lot. So you have to get the right source. The functional medicine principle is this. Intervene at the lowest level necessary to restore balance and optimal function. Peptides are tools and they're powerful tools. But tools are only useful if you built the foundation. And I see this all the time. People want to layer in advanced therapies before they've addressed the basics. It's like, you know, you want to take a GLP1 drug, but you're not changing your diet and you're still eating tons of ultra processed food. Bad idea. Biology just doesn't work that way. Your body runs on the inputs. If you're not getting high quality protein, your muscles can't repair. If you're not strength training, your longevity pathways aren't activated. If you're sleeping five hours a night, your growth hormone and repair cycles are disrupted because you need sleep to repair. If your stress is chronically elevated, cortisol is gonna override everything. If you're deficient in micronutrients like magnesium or zinc, or the B vitamins or vitamin D or omega 3 fats, your cellular machinery simply doesn't have the raw materials it needs to function. If your gut's inflamed and your absorption's compromised, you're also in trouble. You gotta fix that. If your insulin's chronically high from eating tons of starch and sugar, you're. Your metabolic signaling is distorted. Peptides don't fix all that chaos. They amplify whatever environment they're entering. So if your signaling environment is chaotic, inflamed, insulin resistant, sleep deprived, adding more signals isn't gonna fix the system. It may just create more noise. But when the foundation is solid, when you stabilize blood sugar, when you've built muscle, when you've repaired your gut, when you've optimized your sleep, when you've reduced inflammation, well, that's when targeted therapies can potentially enhance performance or recovery in a really meaningful way. So before you ask which peptide should I take? The better question is, have I built the biological terrain, meaning my health that allows my body to respond well to any input, including peptides. Because longevity isn't built from hacks, it's built from habits. So peptides represent an exciting frontier in medicine, but they don't replace fundamentals. They amplify what's already there. If you're considering peptides, well, make sure you work with a qualified doctor. Optimize your lifestyle first. Measure your biomarkers. Get function, health. Functionhealth.com, you can see what your biomarkers are and track those because those will be influenced by the peptides. And it'll also call out who maybe should be cautious to take the peptides. Understand the risks, and understand that health isn't built from a bunch of biohacking tricks. It's built from steady habits over time. Hacks, not the key. Habits are the key. So from muscle, from metabolic resilience, from sleep, from nourishment. Well, peptides may all be part of a future of medicine, but your foundation that's the future of your health.
