Dr Ritamarie  

What if the biggest problem with the peptide trend is not the peptides themselves, but the belief that a signal can replace a foundation? Peptides are being talked about everywhere right now for fat loss, for longevity, gut repair, tissue healing, sleep hormones, inflammation, brain health, anti-aging, and even recovery. And as practitioners, we need to know how to respond, not with blind enthusiasm and not with automatic dismissal either, with clinical discernment. 

Peptides are signals, and signals only work well when the body has the capacity to respond to them. 

In our last episode, we explored GLP-1s, muscle loss, and metabolic resilience. These are among the newest protocols for weight loss, and they're all over the place these days. 

If you want to move beyond chasing the newest intervention and start thinking through complex cases with more clarity, download my free guide Beyond Protocols: A Practitioner's Guide to Root Cause Pattern Recognition. It'll show you how to look at symptoms, systems, terrain, sequence and strategy, so you can stop relying on cookie-cutter protocols and start building personalized plans that truly help people to get well. You'll find the link in the show notes. 

Today, I want to zoom out and look at the broader category of peptides. GLP-1s are peptides. So let's look at the broader peptide conversation. GLP-1s are part of a much larger cultural trend. People want faster results, they want quick fixes, they want to heal faster, they want to lose weight fast, they want younger skin, younger bodies, better sleep, sharp brains, more energy, and a longer health span, but they don't necessarily want to really do the work that it takes to get there. 

The wellness marketplace, of course, has noticed, and peptides are now being touted in med spas, longevity clinics, telehealth platforms, biohacking circles, online communities, and even practitioner training. And some of these conversations are grounded in legitimate physiology, but some aren't. 

Some peptides have FDA-approved medical uses. Others are sold in gray market ways, sometimes labeled for research use, sometimes promoted with claims that go far beyond the existing evidence, and practitioners are caught in the middle, because we want to help people. 

People ask us, “Should I take this?” “Can you help me get this?” “My friend is using this peptide. Should I?” “I heard this repairs the gut, and I heard this reverses aging, and I heard this melts away belly fat.” 

So we, as practitioners, need a framework. Let's start by addressing the question: what are peptides? They are short chains of amino acids. That's it. Nothing magical. In the body, many peptides act as signaling molecules. They help cells to communicate with each other. They influence appetite and inflammation and immune activity and tissue repair, hormone signaling, metabolism, and many other processes. That part's real. 

The body uses peptide signaling constantly. Insulin's a peptide hormone. GLP-1 is a peptide hormone. Many biological therapies are based on peptides or protein signaling. So the concept itself is not fringe. 

Dr Ritamarie (04:00)

The question isn't whether or not peptides can influence physiology. We know they can. The better question is: what peptide for which person, for which purpose, at what dose, from what source, and with what evidence, with what monitoring, and with what foundational support? This is the practitioner-level questioning that we need to do. 

Let's look at the promise versus hype. The promise of peptides is that they may help influence specific pathways. They may support appetite regulation. Who doesn't want that? They may affect glucose metabolism. We know they do that. They may influence tissue repair. They may affect inflammatory signaling. And, they may become part of the future of medicine in very meaningful ways. They already are, in some ways. 

The hype says something different. The hype says: take this and skip the hard work. Take this and reverse aging. Take this and fix your gut. Take this and burn fat. Take this and heal your injuries. Take that and become biologically younger. 

That's where practitioners need to pause, because healing isn't just about a signal. Healing requires raw materials. It requires mitochondrial energy. It requires protein. It requires minerals. It requires blood flow to areas that may be having a hard time. It requires sleep, nervous system regulation, and balanced blood sugar. It also requires good digestion, functionally adequate and efficient digestion. It requires good detoxification capacity and a terrain that can respond to the signals. 

A peptide can send a message, but can the body carry out that message? That's the question, and that's the missing question, the one that's not asked enough. 

What needs to be considered, and often isn't, is how the terrain determines the response. This is one of the most important principles, especially when we're talking about peptides. If someone's inflamed and undernourished and insulin resistant and over-trained, stressed, low in protein, low in magnesium, low in zinc, low in other nutrients, omega-3s, and B vitamins and living in where most people are, sympathetic overdrive, then simply adding signaling molecules is not going to create the expected result. 

The terrain matters. Think about it this way. If you send a repair crew to a construction site, they need the materials, they need electricity, they need clear instructions, and they need access to what they need to use. They also need safety. 

They need workers that are not exhausted. 

When we're talking peptides, peptides may be part of the instruction, but it's not the entire construction crew. That's why practitioners need to come back to root causes. Why is this person inflamed? Not how do we get them uninflamed? Why is this tissue not healing? Not how are we going to get it healing in spite of? Why is the appetite dysregulated and fat accumulating? Why is the sleep poor and the gut lining compromised?

Why is the immune system confused? All these things are going on, and we need to find out why, not just slap a peptide on. Why is recovery impaired? Why are hormones not responding the way they should? 

These are all the questions that practitioners need to be asking, not just which peptide matches the symptoms. There are also regulatory and safety concerns to be considered, and a safety and quality issue is an important thing to look at. 

The peptide marketplace can be confusing. Some peptides are approved medications like insulin used for a specific indication. We don't just slap insulin into somebody who doesn't need insulin. Some are compounded under certain circumstances, and some are sold online as research chemicals with no control over quality. Some are marketed directly to consumers with very little oversight. And quality really matters. We're injecting something into the human body.

Purity matters, stability matters, and dosing matters. We need to know how these are being administered. Some of them are directly in, some of them are through nasal sprays, some of them are oral. And quality matters, cleanliness matters, sterility matters, the interactions between them matter, and appropriate monitoring matters.

The FDA has identified safety concerns with certain bulk drug substances used in the compounding, including BPC-157, which is a very popular one and is warned about the unapproved GLP-1 products that are used for weight loss. This is important for all of us as practitioners to understand, not because we need to become fear-based, but because we need to be responsible. 

Dr Ritamarie (09:03)

People are coming to us with their most valuable asset, their health., and we can't be irresponsible with it. We can't just recommend things, because it's popular. When people are getting products from sources that aren't certain, that aren't approved, and using them without supervision, without medical supervision, and stacking them. Some people are stacking seven, eight, nine, ten peptides a day. How do they work together? Do we know? I don't believe that we do. And they're doing it without medical supervision a lot of times, and they're replacing the foundational care with experimental shortcuts, and when they do, the risk goes up dramatically. 

As practitioners, we don't need to know every peptide protocol, but we need to know how to ask better questions. This is something I talk about all the time. The questions determine the results. 

We want to know if this stuff people are taking, where did it come from? Did somebody prescribe it, or did they find it online on the internet? What dosing are they taking? Is the dosing appropriate for them, for their body, for their situation? What kind of results are they looking for? And what are the possible risks? 

Are there labs that are being monitored to see how it's affecting the body? Are there symptoms that are being tracked? And what else is the person taking? What other meds? What other supplements? What other peptides? What other things are they taking that may not interact properly and may be creating risk?

And of course, what foundational work is being done at the same time? Are they taking peptides and drinking coke and eating MMs and expecting that the peptide is going to save them? Are they sleeping? Are they stressed out all the time? We need to look at the foundations. We know the foundations are the most important thing, and they need to be looked at all the time. We need to be offering responsible care to the people that we're serving. 

As practitioners who care about truly helping people to achieve their health goals and who are dedicated to first do no harm, that's in the Hippocratic Oath, we need to have a practitioner responsibility framework. 

Dr Ritamarie (11:20)

So here's a simple framework you can use when somebody asks about peptides. The first is the signal. What pathway is this peptide trying to influence?

If you don't understand that, you can't say yes or no. Is it appetite? Is it repair, inflammation, sleep, immune balance, hormone signaling, gut integrity, body composition, any number of those? 

The second thing we have to look at is terrain. Does the person have the capacity to respond? Are they eating enough protein? Do they have enough minerals? Is their nervous system in a state of safety so that it can respond? And are they sleeping?

Are they in sympathetic overload? Are they digesting? Is their nervous system hardwired for cortisol and inflammation? Is there inflammation and insulin resistance? All of these things are important to look at. And especially things like: are they under chronic stress? Physical, physiological, environmental, or emotional. 

The third thing I like to look at as part of the framework is evidence. What evidence supports the use of this particular peptide? In this particular person's situation, is it an FDA-approved indication? And I'm not thinking that everything needs to be FDA approved, because there's a lot of problems here with the FDA, as well. But is it FDA approved for that indication? And things can be used under different labeling, but is the evidence based on human trials, clinical trials, or is it just guessing, because we know what the mechanism might be. 

The data from animals may not be mechanistically appropriate here. Is it anecdotal? Is it just marketing? There's a lot of companies out there who are pushing their peptide products, just trying to get people into it, and everybody wants the quick fix. We all want a quick fix, but I've found in 34 years of clinical practice that the quick fix doesn't work. We need to be able to separate these different categories and also look at a fourth category of safety.

Is the product regulated? And especially if you're injecting it. Is it prescribed appropriately? And is it a reliable source? We can't just be getting black market stuff and expecting people to be safe. What risks, what contraindications, what kind of monitoring needs to happen to see if it's effective and to see if it's having any negative side effects? 

Dr Ritamarie (13:46)

The last thing to consider as part of the framework is strategy.

What's the full plan? How does this fit the full plan? What are we doing with food and movement and sleep and the stress management and digestion, blood sugar, liver status, inflammation, detox, all of these things need to be looked at. 

What does success look like? What is the exit plan? How do we know when they don't need it anymore? What happens if they just stop abruptly? We have to make sure we're looking at all these things, before we prescribe these things if it's within your scope to prescribe it, or before you talk to people and say, maybe that's a good thing for you to do. Be careful. This is your health, this is their health that we're looking at. 

The framework will keep you out of the extremes. We also need to avoid being anti peptide, as well, because they can be helpful. There are times when they're very helpful. 

We have to make sure it's right for the person at this particular time. Don't recommend peptides to pregnant women or nursing women. Don't recommend them to people with cancer unless you know what you're doing. These things may be backfiring, as well as all the stuff. 

When we're overly zealous about peptides without really looking at the environment they're being absorbed in, that's not a good thing. 

We need to look at the physiology, look at the biochemistry, look at the person and their needs. Consider their physiology and biochemistry first. Functional peptides. Peptides shouldn't replace functional assessment. And that's really what I'm trying to get at here. 

Peptides don't replace labs. They don't replace nutrition. They don't replace protein optimization. They don't replace sleep or strength training. All those good things that people need to do. A lot of folks are into the peptide craze, and they're looking at, well, I'll take this for healing leaky gut. Meanwhile, they're eating foods and being under stress that causes that leaky gut to precipitate. 

We look at people who are trying to lose weight with peptides, but they're not willing to do the work. We have to be the voice of reason. Peptides don't replace getting a person's nervous system regulated, because dysregulated nervous systems are causing most problems out there. And they don't replace gut restoration through proper food, chewing, proper digestive strategy. 

As part of nutritional endocrinology, we're always asking: what's the signal? What's the receptor response? And what's the downstream effect? What nutrients are required to make this pathway work appropriately? What genetic tendencies might influence the pathway, either in a positive or negative way? What inflammatory or toxic burdens might interfere with the effectiveness? Or the side effects? 

What lifestyle patterns are amplifying the problem? That's the deeper work, and that's what we do, and that's what I think is really important for us as practitioners to be doing right now and to be leading the way. 

In the age of direct-to-consumer health trends, people are hearing about things all over on the internet, on TV, on YouTube, but people need to be able to know how to safely access all these interventions that are out there. What those people don't always have is the wisdom and the knowledge about integrating this into their life safely. They don't always have the clinical reasoning, and that's why they turn to us. 

They don't always have someone asking, what's really driving this problem? This problem that you're having? What's driving it? What's the underlying root cause? Now, why do we fix it as quickly as possible? And no, drugs are bad. So let's do something safer like peptides or herbs or other interventions.

I’m specifically talking about peptides today, but this can apply to the willy-nilly use of supplements that are magical, and the “Just eat what you want and take this supplement and this magic herb and oil from Brazil.” We don't want that to be what people are looking at. And the peptides are kind of looking at that that way. 

Yes, they're safer in many cases than pharmaceutical drugs, but we have to be asking the right questions. What's driving this imbalance? And that's where we as practitioners are essential. People can just go on the internet and get whatever they want, but are they really getting the right reasoning when they do it?

Dr Ritamarie (18:14)

How should we be talking to people about peptides? I think that when someone asks about peptides, you need to get curious. You can say, well, that could be an interesting tool, but let's look at understanding what is the problem you're trying to solve and what does your body have the capacity to respond to. Before we chase a signal, let's look at the terrain. Let's look at the underlying soil in your body. 

Peptides, yes, they can influence pathways. They don't always replace the foundations that allow those pathways to work. 

The language we use with people is very powerful, and it keeps the door open, and it keeps you grounded, and it keeps the person feeling heard without letting marketing drive their clinical plan. 

The peptide trend is part of a much bigger issue in health and on this, I believe. People are exhausted, they're metabolically unwell, they're inflamed, they're sleep-deprived, they're very stressed, very stressed and in sympathetic overdrive.

They're overwhelmed, and they're surrounded by processed food and environmental toxins. The world is a toxic place, and people's systems are being disrupted. Circadian rhythms, the EMFs, and the processed food, and the environmental toxins, all of this stuff is creating havoc in the system. 

Dr Ritamarie (19:30)

What happens is they get to the point where they just want something that feels precise. This particular BPC, whatever, is going to help solve this problem, this particular peptide. Which peptide solves which problem? When we do that, we're getting back into allopathic mode. We're not looking at what's out of balance and how we help people to rebalance. No, we're looking at an allopathic approach in a lot of ways that peptides are being presented. People want that. I totally get that. They want that, because that's what they've grown up to believe. It's fast. 

Fast isn't always foundational, and fast isn't always effective. Advanced treatments are not always appropriate. Sometimes it's just the basics that people need, and the most advanced thing that we as practitioners can do is to identify the real root cause, or the causes, because I don't think there's ever one root cause.

Sometimes the most powerful intervention is as simple as restoring blood sugar stability. It may not seem simple to them at the time, but it's simple. Or improving their digestion of protein, chewing their food, getting into parasympathetic dominant state before eating instead of being in fight-flight mode. 

Dr Ritamarie (20:47)

Correcting iron overload or deficiency, not by simply saying, looking at a lab marker and popping an iron pill, but there's a lot of that stuff. Thyroid conversion, thyroid receptor resistance, all of these things need to be looked at. If we just skip that to jump right in and add a peptide or an herb or a supplement or some sort of magical potion, it's the same as just jumping in with a drug. We're not really solving the problem.

Why is the inflammation there rather than how do I lower and decrease the inflammation? 

Why is there inadequate bile flow as opposed to just giving a cholagogue or something that's going to restore that flow? Maybe that's the right thing to do at the time, but we need to look at what's the cause, because people can't be relying on these expensive and invasive interventions. They need to have the basics and use them as temporary solutions, not these long-term stacking of peptides. 

I know people are taking like seven, eight peptides a day. That's expensive and that's invasive, and that's going right into the bloodstream and bypassing a lot of the things that we have as external defenses. We need to teach them. We need to teach them how to build muscle. We need to teach them how to sleep. These are basic things, they're not sexy, but they are effective. They're foundational.

Foundation isn't inferior, even though it may not be as sexy. Foundational is what makes advanced interventions work safely and effectively when they're appropriate, when they're used in combination with foundational approaches. 

The key takeaway here from me is this: peptides are signals, they're signaling molecules, they're not magic interventions, and they're not automatically good. They're not automatically bad. They're simply tools among the many that we have in our toolboxes. 

As practitioners, we need to be able to match the tools with the person and with the imbalances that they're suffering from. Some of these tools are clinically useful. Some of these peptides are clinically useful, and some of them might be overhyped, and some of them might be risky. 

Just as you wouldn't give somebody insulin, because it's a peptide, and it's safe, if they didn't need it, you could kill them. It’s the same thing with some of these others. We have to know and understand what they're doing in the body. And does this body right now need them? Or is it just overhyped-in marketing? Some of these are going to become part of the future of medicine, the same way insulin has, but we as practitioners need to stay rooted in the principles that don't go out of style. 

Assess the person. Yes, ask a lot of questions. Understand the pathways that are out of balance in this case, support the underlying terrain, protect safety, help the nervous system feel safe, and then monitor, monitor, monitor outcomes. Retest, and never let a trend replace your clinical thinking.
