Dr. Greenblatt is dual board certified in psychiatry and internationally recognized.as a pioneer in functional and integrative psychiatry. He’s widely regarded as the leading expert on the clinical application of low-dose lithium for mental health.Dr. Greenblatt has spent more than 30 years advancing precision medicine-based approaches that move beyond symptom management to address the root causes of mental illness.And after earning his medical degree at George Washington University.Dr. Greenblatt completed his psychiatry and residency there as a fellow in child and adolescent psychiatry.Joined John Hopkins Medical School, and he currently serves as an assistant clinical professor of Psychiatry at Tufts University. He is a prolific author. Dr. Greenblatt has written 9 books, including his newest book, Finally Hopeful. in… available in January of 2026. We can ask him about this today.And his bestsellers finally focused the breathwork, natural treatment plan for ADHD,Answers to anorexia, Functional and Integrative Medicine for Antidepressant withdrawal, and nutritional lithium, and Untold tale of Mineral and Transforms Lives, that heals the brain.He has founded, in 2019, the Psychiatry Redefined, a leading educational platform training clinicians worldwide in functional and integrative psychiatry. He is a sought-after international speaker. Dr. Greenblatt regularly lecturesOn nutritional psychiatry and the transformative role of functional medicine.I am super excited to have him here with us today. This is going to be a pleasure. You guys are going to love this conversation that we are going to have. And I am going to pick his brain today on functional and integrative psychology and psychiatry, and combining nutrition, biochemistry, and lifestyle with mental health care.I’m really, really happy to have Dr. Greenblatt with us, so I am going to bring him on, and we are going to have this amazing conversation with my friend.Welcome back to Let’s Talk Wellness Now. I’m your host, Dr. Deb, and I have with me Dr. James Greenblatt, who I have followed for… we were just chatting about this for over 20 years.He is amazing in what he is doing, and we are going to have this conversation today about integrative psychiatry and the future of mental health. So, welcome to the show, Dr. Greenblatt. James greenblatt md 03:20Thank you, Dips, good to be with you. Dr. Deb Muth 03:22Now, you’ve been pioneering this integrative psychiatry for decades. What really inspired you to bridge nutrition and psychiatry long before it’s become mainstream? James greenblatt md 03:35You know, I developed an interest in college, you know, studying nutrition, and then I remember writing papers on orthomolecular psychiatry, high dose, vitamin B3 for schizophrenia.So, I really did not think I’d be a psychiatrist. I wanted to be a pediatrician when I went to medical school, but, just early interest in nutrition and brain function.And it’s been my career now for 30-plus years. Dr. Deb Muth 04:05Wow. Can you define what integrative psychiatry actually means, and how it’s different from traditional psychiatry for most people who wouldn’t be familiar with that term? James greenblatt md 04:17Sure, I mean, I have to add the word functional as well. I mean, I think, you know, I call myself a functional psychiatrist, but for most of my career, and every book, and everything I did, I would have to use words like functional and integrative.Medicine for mental illness. And, you know, I define integrative medicine as the… Adjunctive lifestyle, mindfulness. And diet, sleep, and exercise. Dr. Deb Muth 04:46Mmm. James greenblatt md 04:46And I kind of use the term functional for kind of a deeper root cause dive, looking at nutritional deficiencies, looking at hormones, looking at genetics. And, you know, to treat patients with mental health challenges, we need both integrative and functional medicine. Dr. Deb Muth 05:05That’s awesome. You know, in our integrative space, we often kind of joke that there’s no such thing as a Prozac deficiency, right? Can you explain to our listeners how nutrient deficiencies, gut health, or inflammation can play a role in mental illness? James greenblatt md 05:23Sure, I mean, I think the most importantBeginning of this conversation would be that, you know, 10 people with depression, there might be 10 different underlying factors. Dr. Deb Muth 05:35Yeah. James greenblatt md 05:35And we do know that there’s not an antidepressant deficiency, so we have to look deeper. And… and that’s,just different than our current psychiatry model, where it’s just symptomatic-based medicine. Everyone who’s depressed. It’...

    Apr 27 2026
    Dr. Deb Muth 0:03What are the answers to your child’s chronic allergies, ADHD, or autism?weren’t just in another prescription, but in restoring balance to their body chemistry. Today’s guest has spent nearly two decades uncovering those answers through integrative and biomedical medicine. That’s a mouthful, isn’t it?Helping children heal when nothing else seemed to work.This is the conversation about science, compassion, and changing the future of pediatric care.Welcome back to Let’s Talk Wellness Now. The show where we uncover the root causes of chronic illness, explore regenerative breakthroughs, and empower you with the practical tools to heal.

So get ready for a conversation that will open your mind and heart to the possibilities of when medicine truly becomes holistic.If you guys can insert the ad in here, that’d be great.Well, welcome back. I’m so excited to have Dr. Usman with me today. I have known her for, oh my gosh, 15, 17 years, something like that. We’re aging ourselves. Anju 02:32Oh, yeah, when we were in our 20s, right? Dr. Deb Muth 02:35Yes, exactly. So, welcome back, and I am so excited for you to be here, because you have literally helped thousands of families over the years.But I’d love for you to share a little bit about your journey, kind of who you are, what drew you into exploring integrative and biomedical approaches for helping children and families. Anju 02:58I think my journey is similar to a lot of you out there, the audience. I mean, we’re looking to help our families, and our kids, and ourselves, and I was doing my residency at Cook County Hospital, downtown Chicago, in the 80s.And I thought, oh my goodness, if I could take care of the sickest patients, then I can take care of anybody. So I came from Indiana, and I went to Cook County, and my children, my eldest daughter, started having, severe allergies and asthma, really, really at a young age.And I went to, like, my residence, and I went to my attendings, and I said, this baby is wheezing. And they told me, babies don’t have asthma.And I said, she has all the symptoms of asthma. She has asthma. And I remember with, in her crib, I would just nebulize her, you know, and I was like, what is going on?And I figured out that she had a lot of food allergies, and I was nursing her, eating the foods that she was allergic to, and back then, in the 80s, you know, we didn’t have the internet, we didn’t have Whole Foods, and I just…being a doctor, and I didn’t even know what to do, and I felt so hopeless. And I thought, gosh, you know, I’m a doctor, I have these, like, skills, I have… people I can talk to, and I still feel so… it’s so difficult. And then this… my particular daughter, the oldest one, her name is Priya, and she developed severe, asthma, and I couldn’t figure it out. She was in junior high. Every time she would walk into the lunchroom, she would have a severe asthma attack.And I’ll be like, what’s going on? What’s going on? I kept her home over the weekend, she was better. I sent her back to school, she was bad again.And we figured it out that it was other people eating peanuts. Dr. Deb Muth 04:54Severe peanut allergy. Anju 04:56And I went to the school, and I said, she…can you, like, put her somewhere else? Can… they said, oh, no, that’s not fair to other kids and their food. And this was in the 90s. Dr. Deb Muth 05:10Yeah. Anju 05:10And so, I just…You know, my heart goes out to families who are struggling to find answers for their kids, and my daughter Priya, the one I told you about, she ended up passing away from a peanut allergy.And so, I’ve just… Dr. Deb Muth 05:26Yeah. Anju 05:27My heart goes out to parents and my own kids and their illnesses.And so I just started working with families, with kids, andIt just kind of grew from there. Dr. Deb Muth 05:40Yeah. Yeah. Yeah, and I think being a mom who went through that yourself, and…was seen but not heard, and turned away from the traditional medical community, you’re forced to start finding answers on your own. And we always feel like we’re on an island by ourselves in the medical world when we’re doing that. Anju 06:...

    Episode 261 – Root-Cause Healing and Whole-Body Wellness
    Apr 18 2026
    Dr. Deb Muth 0:03What if everything you’ve been told about getting healthy is backwards?What if chasing symptoms with pills, procedures, and quick fixes is exactly why you’re still sick? Tired, inflamed, and frustrated. Today, I’m sitting down with Dr. Holly Donahue, a naturopathic doctor who walked away from corporate burnout to discover the truth.Your body already knows how to heal. You just need to remove what’s blocking it, and give it what it’s missing. If you’re done with Band-Aid solutions and ready for real, lasting transformation, this conversation changes everything. Welcome back to Let’s Talk Wellness Now, the show where we uncover the root causes of chronic illness, explore cutting-edge regenerative medicine, and empower you with the tools to heal. I’m Dr. Deb, your medical detective, and today, we’re diving into the hidden truth about whole body wellness, and why treating symptoms will never give you the vibrant health you deserve. I’m joined by Dr. Holly Donahue, a licensed naturopathic doctor with over two decades of clinical experiencing Helping high performers heal from burnout, chronic fatigue, hormone imbalance, and stubborn weight issues. She’s the founder of Simple Health, and she’s here to share the science-backed approach to root cause healing that addresses your body, mind, and spirit, not just your lab values. If you or someone you love has been diagnosed with a chronic condition, or is struggling with unexplained symptoms like fatigue, brain fog, hormonal chaos, or chronic inflammation. This episode is for you. Please share it with them. So, as usual, grab your cup of coffee, tea, or whatever helps you unwind, settle in, and let’s get started on your journey to deeper healing. And we’ll be right back after a word from our sponsor. All right. So, Dr. Donahue, let’s start with the question that’s on everyone’s mind, right? How did you transition away from corporate and into the world of, naturopath… natural medicine, naturopathic medicine, root cause medicine, all the wonderful terms we’re using for this these days? Dr. Holly Donahue 02:56Yeah, first of all, thanks for having me, Dr. Debb. I so appreciate it, and that is a beautiful question, and I will share with you my health journey and why I got into this, and… how I got to do this amazing work, right? Because I always believed, for me, my higher being is God, and it walked right into me, right? Because I was pretty happy in the apparel industry. So, just as you said, I was in the apparel industry, I, my education doesn’t really matter, but double, like, marketing and textile marketing, and I was in design, and I was working in design. from LA to London to the East Coast. And 2 days after September 11th, to sum it up, I got laid off. Even though I had been pulled out of a job where my vice president of the company was like, I want you to come down here with me, and the apparel industry, you’re switching every two to three years. For those that don’t know it, that’s just how the journey works, and I was known as a changemaker in the field. And so, here we are two days after September 11th, and I was seeing a naturopath, and I was, let’s see, 29 to 30, right? And so, prior to that, the reason why I searched out for a naturopath was because in my teenage years, and… Up until that time, I was suffering with horrible menstrual cramps and horrible depression, hence why I moved to LA, thinking if I was in the sun all the time, my life would change, which we all do, change our place, change our time, things will change. Had nothing to do with family or roots, but I thought, if I’m around sunshine all the time, I won’t be depressed. Well, wherever you go, there you are, because it went with me, right? So I had my foot down to the ground, and I was just like, I am committed to not living life like this, right? Even at 7 years old, I had strep ear all the time, and my mom’s like, we’re gonna have your tonsils out, and I’m like, no we’re not. And she goes, no, you’re gonna feel so much better, no more strep ear. And I’m like, God gave them to me for a reason, you’re not taking them out. She’s like, okay, like, I was really strong. And so, let’s wind up to 2 days after September 11th. Prior to that, I had started to retake chemistry and biology, because I haven’t taken it since my textile years, which was a different chemistry, right? And so, I thought, well, I’ll just start and see where it goes, because my naturopath at the time. Dr. Dadama was like, we need more naturopaths, and I’m like, I’m really good where I am. I love what I do, I love corporate America, I love designing, I love product development. And he’s like, no, no, no, so he kept talking. Well, when this all fell… And 2 days after September 11th, I raised my hand and I said, God, I hear you. I went off to naturopathic medicine school in my 30s. And I never looked back, and I just really ...

  • Episode 260 – How Trauma Passes Through Generations: Epigenetics, Trafficking and Chronic Illness

    Episode 260 – How Trauma Passes Through Generations: Epigenetics, Trafficking and Chronic Illness
    Apr 13 2026
    Dr. Deb Muth February 2026, 3 million documents released, a network exposed. But here’s what no one is sayingThe trauma of trafficking doesn’t end when the victim escapes It doesn’t even end when that survivor’s lifetime. It writes itself into DNA. It alters the stress response of children not yet born. And it creates epigenetic markers that echo through 3, 4, and even 5 generations. This is not a metaphor, this is molecular biology. And if we don’t understand how deeply trauma sees itself. Biologically, genetically, and spiritually, we will never understand why autoimmune disease, addiction, and chronic illness are epidemic in families that carry this hidden history. Today, we’re going deeper than headlines. We’re going into the cells, the genes, and the soul. Welcome back to Let’s Talk Wellness Now. We’re here to uncover root causes, explore regenerative medicine, and empower you to heal from the inside out. I’m Dr. Deb, your medical detective, and today we’re confronting one of the most important and least discussed wellness topics of our time. How the exploitation and trafficking of women and children doesn’t just harm individuals, it damages bloodlines. And if you’re someone who carries an unexplained chronic illness, autoimmune disease, addiction, or trauma that seems to have no clear origin, this episode may finally connect the dots. Grab your cup of tea or coffee, settle in, and let’s go deep into this subject. Can you put an ad sponsor right here before we get started? Let’s start with what just happened. In February of 2026, the Department of Justice released over 3 million pages of documents related to Jeffrey Epstein. According to The Guardian, on February 2nd, 2026, these files contained allegations that Epstein didn’t just abuse women, he provided them to other powerful men. One accuser identified Harvey Weinstein from a photo lineup. Describing coercion and payment. Another FBI document described threats of force. Lativia launched a criminal investigation after the files linked Epstein’s network to modeling agencies overseas. But here’s what I need you to understand. As a practitioner who treats trauma survivors, Epstein’s operation was not new. It was ancient. From Mesopotamian slave codes to Roman markets to the transatlantic trade, trafficking has always been about the same thing. Power, and exploiting vulnerability for profit. The tools change. Private jets instead of ships, social media instead of market squares. But the wound, it’s identical. And that wound… It doesn’t heal when the victim is freed. It embeds itself into biology. Let me explain what happens when a human being experiences the kind of trauma that trafficking creates. The immediate biological response. When someone is trafficked, their body enters a state of chronic survival mode. The autonomic nervous system, which controls unconscious functions like heart rate, digestion, immune response, it gets locked into a fight or flight. Cortisol, the primary stress hormone, floods the system. At least, at first. This is protective. But when the threat never ends, when abuse is daily, when escape is impossible, cortisol stays elevated for months and even years. And here’s what chronic cortisol does. It suppresses immune function, making the body vulnerable to infections, cancer, and autoimmune disease. It disrupts the gut microbiome, leading to leaky gut, food sensitivity, and systemic inflammation. It dysregulates hormone production, thyroid sex hormones, insulin, and it creates metabolic chaos. It damages the hippocampus, the part of the brain region responsible for memory and emotional regulation. But it goes deeper than that. Cellular memory, trauma written into our tissues. Research published in the Biological Psychiatry of 2025 and Frontiers in Psychiatry 2025 shows that trauma doesn’t just affect the brain, it reprograms cells throughout the body. Mitochondria, the energy factories inside every cell, shift from producing ATP energy to producing reactive oxygen species, stress signals. This is why trauma survivors often develop chronic fatigue syndrome. That cortisol, over time, starts to dive down, and eventually can’t be produced when it’s supposed to be during a traumatic episode, and it stays at this low level, creating what we now know as chronic fatigue syndrome. Inflammatory genes turn on and stay on, even after the threat is gone. This is why we see such high rates of autoimmune disease, lupus, rheumatoid arthritis, MS, inflammatory bowel disease, in trafficking survivors. The fascia, the connective tissue that wraps every muscle and organ, stores trauma physically. This is why survivors develop chronic pain, fibromyalgia, and tension that no amount of massage can release. The body literally remembers the violation at a cellular level. The ACE study, Childhood Trauma as a Disease Predictor, the CDC’s Adverse Childhood Experiences Study in 2025, showed that 64%...

  • Episode 259 – The Desiccated Thyroid Crisis: FDA’s Unseen Impact & Corporate Manipulation

    Episode 259 – The Desiccated Thyroid Crisis: FDA’s Unseen Impact & Corporate Manipulation
    Mar 31 2026
    Deb (00:03.606)Within the next seven months, up to 1.5 million Americans could lose access to a medication that they’ve relied on for decades. Not because it’s dangerous, but because a pharmaceutical giant may have lobbied the FDA to eliminate their competition. And if you’re one of them, your doctor may already have told you about this issue and stopped prescribing it.This isn’t a conspiracy theory. This is documented in federal court filings. This is happening right now. And the company that stands to profit, well, they’re the same ones manufacturing the only product that might survive.Today on Let’s Talk Wellness Now, we’re exposing the desiccated thyroid extract crisis, the corporate manipulation behind it, and what you need to do right now to protect your health. Stay with me because I’m about to share what could save your access to the medication keeping you alive.Welcome back to Let’s Talk Wellness Now, the show where we uncover the root causes of chronic illness, expose regulatory capture in healthcare, and empower you with the tools to advocate for yourself. I’m Dr. Deb, naturopathic doctor, your medical detective, and today we’re diving into one of the most consequential and corrupt healthcare decisions affecting patients right now. If you or someone you love takes Armour thyroid, NP thyroid, or any desiccated thyroid extract,for hypothyroidism or if you’ve struggled to find a thyroid medication that actually works for your body, this episode is absolutely critical. And if you have celiac disease, gluten sensitivity or corn allergies, what I’m about to reveal will make your blood boil. Now grab your cup of coffee, don’t forget your notebook and settle in because what’s happening to this medication right now is a masterclass in how pharmaceutical companies use regular Deb (02:06.544)agencies to eliminate competition, control markets, and price gouge patients. And I have all the receipts. Deb (02:20.982)Let me start with what might surprise you. Desiccated thyroid extract, or DTE as we call it, is actually one of the most oldest thyroid medications in the world. And I mean old. From the 1890s through 1970, this was the standard treatment for hypothyroidism.Now let’s really dive into that. From the 1890s to the 1970s, this was standard hypothyroidism treatment.In 1965 alone, and this is documented in peer-reviewed literature published in the Journal of Clinical Endocrinology and Metabolism, approximately four out of every five prescriptions for thyroid hormone in the United States were of natural desiccated thyroid preparations.The Journal of Clinical Endocrinology and Metabolism is a very high-end journal. Now think about that. This wasn’t some fringe therapy. This was mainstream medicine. Armour Thyroid, the most recognizable brand name, has been manufactured since the early 1900s, well over a century ago.and this is cited again in NIH bookshelf. When the FDA was officially established in 1938, Arbor thyroid was already on the market. And this is important and I want you to understand why. Under the federal Food, Drug and Cosmetic Act, any drug that was already being marketed before 1938 was automatically grandfathered into the system. That means it didn’t have to Deb (04:08.112)go through the formal FDA approval process. And this again is cited under the Federal Food, Drug and Cosmetic Act, grandfathered drugs and exemptions. And this is crucial to understanding what happens next. By the 1970s, synthetic levothyroxine, brand name Synthroid and generics became the preferred treatment. Hmm, wonder why?It was easier to standardize, came into consistent doses, and worked well for most patients, and could be mass manufactured. By the 1980s, levothyroxine had largely replaced desiccated thyroid in clinical practice, according to the American Thyroid Association 2014 guidelines for the treatment of hypothyroidism. But here’s what matters. Some patients…a very significant minority of them, never felt right on levothyroxine alone. Despite their lab work looking normal, they still had fatigue, brain fog, weight gain, cold intolerance, and depression.These patients often found relief when they switched back to their desiccated thyroid, which contains both T4 and T3 hormones, the way human thyroid naturally produces them. And this is not anecdotal. This is documented in randomized double-blind crossover studies published in Endocrine Practice.For decades, that was fine. Their doctors prescribed it, insurance sometimes covered it, patients were getting better, and the system worked really well. Until August 6th of 2025, just a short time ago, everything changed. On that date, the FDA sent letters to manufacturers, importers, and distributors of desiccated thyroid extract products stating that these medications would need an approval.

    Episode 258 – Investigational Peptides: What’s Promising, What’s Hype & What You Must Know
    Mar 17 2026
    Dr. Deb Muth 00:03Well, welcome back to Let’s Talk Wellness Now. I am your host, Dr. Deb. And what is the most talked about peptides in functional medicine? aren’t actually FDA approved. Not because they don’t work, but because no one’s funded the research to prove it yet. The truth is some of the compounds that dominate wellness forums, BPC-157, TB-500, thymosin beta-4, epitalin occupy a fascinating space between breakthrough science and unregulated experimentation. In today’s episode, we’re stepping into that gray zone, the world of investigational peptides to separate mechanism from marketing. I’m going to walk you through the science that actually actually shows and where it stops, how to evaluate claims when human data don’t yet exist and the quality, purity and safety red flags that you need to recognize. I created in a previous episode, Dr. Deb Muth 01:06so go check that one out. And why honesty is the most important prescription in peptide medicine. If you’ve ever wondered whether these research-only peptides are the frontier of healing or the next functional medicine fad, this episode is for you. So grab your cup of tea or coffee, get comfortable, and let’s talk about what it really means to use peptides that are promising, but still under investigation. So we’re going to break just for a second here and have a word from our sponsor. It is because of them that we stay on the air. So thank you for this. And we will be right back. Did you know sweating can literally heal your cells? Infrared saunas don’t just relax you. They detox your body, balance hormones and boost mitochondrial energy. I’m obsessed with my Health Tech sauna. And right now, you can save $500 with my code at healthtechhealth.com slash dr-muth-req-25. Dr. Deb Muth 02:15All right, guys, welcome back. Let’s dive into investigational peptides, the evidence gap. So the following peptides we’re about ready to discuss are extensively in integrative, functional and regenerative medicine circles. They may have intriguing mechanisms and promising preclinical data. However, they lack FDA approval and the evidence quality varies dramatically. from interesting preliminary research to essentially no human data at all. And this distinction is really critical for maintaining scientific integrity. So let’s talk about immune-modulating peptides. There’s thymus and alpha-1, and this is an international story on the thymic peptides. Thymusin alpha-1, known as TA1, is marketed internationally as zidaxin. Dr. Deb Muth 03:16It’s a 28 amino acid polypeptide originally isolated from thymusin fraction 5, which was extracted from bovine thymusin tissue. Modern production uses synthetic peptide synthesis. The thymus gland is located behind the sternum and is the primary site for T cell maturation and thymic peptides like TA1 play roles in the human system development and regulation. Now, I love thymus peptides. I love thymus glandular products. I’ve used thymus glandular products for decades. Ground up animal thymus gland is basically what it is. There’s a couple of different supplement companies that I’ve used over the years that are amazing with this. and they do a fantastic job and they really do help to support the immune system. So when thymus peptides came out, it was really exciting because it took the whole idea of thymus support to a new level. Dr. Deb Muth 04:17The mechanism actually behind the thymus in alpha-1 is complex and involves multiple aspects of immune function. At the cellular level, TA1 enhances T cell maturation and differentiation, particularly the development of helper T cells and cytotoxic T cells. It modulates T cell receptor expression and can influence the balance between Th1 cell-mediated immunity and Th2 humoral immunity responses. And it also enhances the natural killer cell activity and modulates dendritic cell function, which are critical for antigen presentation. and initiation of adaptive immune responses. And on the cytokine level, TA1 influences production of interleukin-2, IL-2, interferon gamma, IFN-Y, and interleukin-10, IL-10. Dr. Deb Muth 05:19These create immune modulatory rather than simple immune stimulatory effects. This is a very important distinction because TA1 appears to help balance the immune system rather than simply ramping this up which theoretically makes it safer in conditions where immune overstimulation would be a problem, such as an autoimmune disease. Hashimoto’s, autoimmune, lupus, Sjogren’s, any of those autoimmune diseases, we don’t want to overstimulate their immune system. So you want to use a product like this that’s non-stimulating. Now, the regulatory status on TA1 is geographically variable and represents one of the challenges in discussing this peptide with patients. It is not FDA approved in the United States. However, it is approved in several other countries for specific conditions. Dr. Deb Muth 06:19In Italy, it’s ...

And there’s a whole variety of reasons why we have sexual dysfunction. 1:42 And when we’re talking about sexual dysfunction, we’re not just talking about it doesn’t work, right? Or I can’t 1:48 reach orgasm. A lot of it is around desire and um the thought of it and 1:54 wanting to connect, wanting to be kinder to one another, wanting to be touching 2:00 one another. A lot of it resolves or revolves around that. And so there are some peptides that can help us and I’m 2:08 really excited to be able to talk about those today. So the first one is called PT-141. 2:14 This targets the brain not the periphery. Right? So for many women I 2:20 will always tell you sex starts between here. It is a brain thing for us. It is 2:26 not necessarily a physical thing. For guys that’s a little different. It’s very physical. For women it’s all in our 2:32 brain. So tip for you men that are listening. You have to prime your woman’s brain first if you want her to 2:38 have sex with you that night. You have to be nice to her. You have to bring her flowers. Do the dishes for her. Do 2:45 something kind. Bring her a cup of coffee or tea or a glass of wine. Take her to dinner. You have to woo her. And 2:51 I don’t care how long you’ve been married. That has to happen. And tip number two, don’t say anything stupid 2:57 that day. I’m just being honest. When you guys say things that make us upset, 3:03 that lingers with us for the rest of the day. And it’s it’s a turnoff for us. And 3:08 for a lot of women, we can’t get past that when it comes time to snuggle at night. And sex doesn’t always have to be 3:14 at night either. So, you can tell I really love talking about this conversation, but we’re going to get into the peptide part of it because this 3:21 is going to help people. So, um, PT-141 is marketed as I’m going to slaughter 3:28 this name, Vali, and it represents a fundamentally different approach to 3:34 sexual dysfunction than the PDE5s inhibitors like Slenden, Viagra, 3:40 Tedataphil, which is Seialis. And while the PDE5 inhibitors work specifically by 3:47 enhancing blood flow to the genital tissues, PT-141 works centrally in the brain by 3:54 modulating neural s neural circuits involved in the sexual desire and 4:00 arousal. Now PT-41 is a cyclic hpatipeptide. It’s seven amino acid 4:07 peptide arranged in a cyclic structure that acts as a melanoortin receptor 4:13 agonist and with particularly the infinity for MC3R and MC4R subtypes. 4:20 It’s actually a metabolite of the melanotan 2, a peptide originally 4:26 developed for tanning that was also found to enhance sexual desire in early 4:31 studies. Now the melanoortin system in the brain is involved in multiple functions including energy homeostasis 4:39 but it also is involved in sexual motivation and arousal behaviors. The FDA approved PT-141 in 2019 specifically 4:48 for the treatment of acquired generalized hypoactive sexual desire 4:54 HSDD in permenopausal women. So for the first time we have a medication that was 5:01 approved by the FDA to use for women for sexual dysfunction. We have had all of 5:07 these seialis tedataphil viagros for men but we had nothing for women. And so 5:12 this is amazing that this is available for women and approved by the FDA. It’s a big deal. This represents the first 5:19 and only FDA approved medication specifically targeting these circuits of sexual desire ...

    Episode 256 – How Peptides Work, Benefits, and FDA-Approved vs Off-Label Use Explained
    Feb 27 2026
    What if the reason you’re not healing isn’t that you need another diagnosis? 0:08 It’s that your cells aren’t receiving the right signals. Because the body doesn’t run on diagnosis, it runs on 0:16 communication. And peptides are one of the most powerful, most misunderstood 0:21 tools we have for cellular signaling, immune balance, tissue repair, gut 0:27 lining support, metabolic control, brain signaling, sleep cycles, and even sexual 0:35 wellness. Today, I’m going to do what most people won’t. Define peptides in 0:41 plain English for you. break them into categories by what they’re best at and 0:47 tell you which ones are FDA approved on the list and which ones are commonly 0:53 used off label or investigational with the evidence that actually says these 1:00 work. This is going to be a powerful episode and if you’ve ever felt like you’re hearing hype without clarity, 1:07 this one’s for you. So, as usual, grab your cup of coffee or tea and settle in 1:13 as we talk about peptides that can fit into your healing journey. We’re going 1:19 to have a short word from our sponsor. You know, we got to do that. That’s how we stay on the air here. So, we will be 1:26 right back after this. Did you know sweating can literally heal your cells? 1:32I nfrared saunas don’t just relax you. They detox your body, balance hormones, 1:37 and boost mitochondrial energy. I’m obsessed with my health tech sauna. And 1:42 right now, you can save $500 with my code at healthtechalth.com/drmuthqen25. 1:54 All right, here we go, guys. I am excited to dive into peptides with you. 2:00 So understanding peptides is foundational, right? And I’ve been 2:06 studying peptides now for about nine years. Um, and I find that they are 2:13 incredible. Um, so I want to break down for you what peptides actually are, what 2:19 they do, and some of the top peptides that are available today, and how they 2:25 can be utilized. Because I think it’s really important. And I think it’s it’s there’s a lot of confusion out there about what these things actually are and 2:32 are they safe? Are they not? When do we use them? What’s the science behind them? So, we’re going to dive in and 2:38 we’re going to talk about all things peptides. So, let’s get ready here. Here we go. So, peptides are short chains of 2:45 amino acids and they typically range anywhere from 2 to 50 amino acids and 2:51 they’re linked by peptide bonds. So think of them as the superglue that holds the amino acids together. They sit 2:58 between the amino acids and they are full proteins in terms of their size and 3:04 their complex structure. And what makes peptides particularly interesting in 3:10 medicine is their role as signaling molecules. They’re essentially the 3:15 body’s text messages carrying specific instructions to cells and tissues. And 3:21 unlike our proteins which often serve as structural roles or act as enzymes, 3:28 peptides typically function as hormones, neurotransmitters and growth factors and 3:33 they bind to specific receptors on the cell’s surfaces or within the cells and 3:39 they trigger this effect. It’s like a cascade effect of a biochemical reaction 3:45 that ultimately changes the cellular behavior. So basically, it’s changing 3:50 the way the body’s cell structure acts. And this is why peptides can be so 3:56 incredibly powerful and therapeutic when you introduce the right peptide signal. 4:02 Now, you could theoretically redirect cellular processes toward healing, 4:07 towards metabolism, immune balance, tissue repair. Any of those things can 4:14 be manipulated to do a certain thing once we add the peptide. The challenge 4:19 in peptide medicine though lies in distinguishing between those peptides that have been rigorously studied, 4:26 proven safe and effective and approved by regulatory bodies like the FDA versus 4:31 those that exist in what we call the gray zone of a promising clinical data. 4:36 But they really lack human validation so far. And this distinction is critical because the presence of a plausible 4:43 mechanism does not guarantee safety or efficacy in living humans. So, this is 4:50 really important and we’re going to dive in and look at some of the research on all of these different peptides that are 4:56 available and I’m excited to say there’s some amazing peptides being studied right now that unfortunately are not 5:01 available. But I can’t wait to see them hit the market for us because it is going to be a gamecher as far as health 5:09 and longevity. So there is a quality control issue and there is a hidden 5:14 variable in peptide medicine with this and it’s one of the most underappreciated aspects of peptide 5:21 therapy particularly for non-FDA approved peptides. It’s quality control. 5:26 When we discuss pharmaceutical medicines, we take for granted that the pill contains what the label says. Not 5:32 always true depending on where it comes from. ...
