Episode Description:

Everyone is calling it nature's Ozempic. That is marketing. And it is doing a total disservice to what berberine actually does.

Berberine is not a GLP-1 drug. It does not work the same way. The weight loss outcomes are not comparable. And if you are taking it expecting to drop 15% of your body weight, you are going to be disappointed. But here is what the research actually shows, and why Dr. G takes berberine every single day.

The clinical evidence on berberine for blood sugar, cholesterol, insulin resistance, and gut health is genuinely compelling. A three month randomized controlled trial in newly diagnosed type two diabetics showed reductions in HbA1c, fasting blood glucose, and post-meal blood glucose that were comparable to metformin. A 2022 meta analysis confirmed it hits triglycerides, total cholesterol, LDL, blood pressure, and insulin resistance markers simultaneously. And the gut microbiome research is a piece almost nobody is talking about.In this episode, you will learn:

 •  What berberine actually does in the body through the AMPK pathway, why it is not a GLP-1, and what to realistically expect from it

 • Why standard berberine has a major absorption problem, what dihydroberberine is and why it may deliver 2 to 4 times more into circulation at a fraction of the dose

 • Exactly how to buy berberine intelligently, what standardization means on a label, which forms to choose, and what to avoid.

Episode Description

You have been looking for yourself everywhere but inside yourself.

In this fully channeled episode, Dr. G goes inward and lets the voice within speak directly to you. Not about supplements. Not about protocols. About the thing underneath all of it. The parts of you that have been buried underground since childhood. The parts you decided were too much, too painful, too unlovable to let be seen. The parts that are still waiting.

This episode is about what healing actually is. Not a process you earn through the right habits, but a remembrance of who you already are.

In this episode, you will hear:

 • Why the love you have been seeking from everyone around you has always existed inside of you, and what it actually takes to come back to it

 • The truth about healing as a return to your natural state, and why no disease can survive a human organism that is fully in alignment

 • Your soul contract: why you came here, what your purpose actually is, and how embodying who you are changes the people around you without saying a single word

Take a deep breath. Open your heart. Let this one move something.

You could be eating well, working out, and doing everything right and still carry stubborn fat around your midsection that will not move. That is not a willpower problem.

Visceral fat is the fat that wraps around your organs deep inside your abdomen, and it behaves completely differently than the fat under your skin. It is metabolically active, releasing inflammatory signals into your bloodstream around the clock and driving insulin resistance, high blood pressure, and metabolic syndrome. Most people have no idea that specific supplements have actual clinical data showing they target visceral fat directly.

In this episode, Dr. G breaks down five supplements with real research behind them, what the studies actually measured, and the exact doses used.

In this episode, you'll learn:

 • Why berberine has to be taken three times a day with meals to work, and the meta analysis showing real reductions in visceral fat and waist circumference

 • The randomized controlled trial where resistant starch led to over 6 pounds of measured visceral fat loss in 8 weeks, and how to dose it without destroying your gut

 • Why EPA dose matters more than total fish oil, the 1800 milligram number from the research, and why 45% of fish oil on shelves has already gone rancid

Plus the role of magnesium in insulin resistance and visceral fat storage, why EGCG only works alongside exercise, and Dr. G's week by week protocol for building all of this into your routine.

Episode Description

Heal Thy Self has never done a show on eye health. Until now. And this conversation goes a lot deeper than seeing clearly.

Dr. Bryce Applebaum is a functional neuro optometrist who rewires the connection between the eyes and the brain. Vision is not the same as eyesight. Eyesight is how you focus light. Vision is how your brain tells your eyes to move, converge, track, and make sense of the world. And in 2026, with the average adult spending over seven hours a day on screens, that system is under more stress than it has ever been.

In this episode, you'll discover:

 • Why your prescription should not get stronger every year as an adult, and why a worsening prescription is a sign your brain is adapting to stress, not a normal part of aging

 • The connection between functional vision problems and ADHD, including why convergence insufficiency and eye turns are diagnosed far more often in kids labeled with ADHD, and how vision training has gotten patients off medication entirely

 • Why blue light blocking glasses are not enough, what is actually causing your brain fog and eye fatigue after hours on a screen, and the overnight contact lenses that reshape your cornea while you sleep

Plus the foods that protect your eyes, the foods that accelerate macular degeneration, and why vision belongs at the top of your list if you are dealing with brain fog.

Andrew Huberman takes it. Peter Attia has been talking about it for years. Every serious longevity researcher has an opinion on it. And by age 40 to 60, your levels have already dropped by 50%.

NAD+ is one of the most important molecules in your body. It powers energy production in every cell, repairs DNA damage every single day, and activates the cellular pathways that regulate aging, inflammation, and metabolic function. The biology is not hype. But the way most people are taking it right now almost guarantees it is doing nothing. And Dr. G is done watching people waste their money on the wrong molecule in the wrong form at the wrong dose.

In this episode, you will learn:

 • Why you cannot raise your cellular NAD+ levels by swallowing NAD+ directly, what happens to the molecule in your digestive tract, and the precursors that actually work

 • The clinical research on NR vs NMN, which one has more published human trial data, which one the longevity research community is most excited about, and why sublingual delivery changes everything

 • Why the serving sizes on most NAD+ labels are set to make the price look reasonable rather than match the research, and what a therapeutic dose actually looks like

Plus the specific brands Dr. G uses and trusts, and how to test your own intracellular NAD+ levels before and after to see if your stack is actually working.

Episode Description

You might be sleeping the right number of hours and still waking up exhausted. The problem isn't how much you sleep. It's when.

Dr. Michael Breus is a clinical psychologist, board certified sleep specialist, and the world's leading authority on chronotypes — your genetic sleep schedule that governs not just when you sleep, but when you should eat, exercise, have sex, drink coffee, ask your boss for a raise, and do your best creative work. Over 3.5 million people have taken his chronotype quiz. The results have changed lives, saved jobs, and transformed relationships. This is his second time on Heal Thy Self and Dr. G says it was worth the wait.

In this episode, you'll discover:

 • Why the 5am club and mouth taping are two of the worst ideas in sleep, and what the research actually says about both

 • The thermoregulation secret behind why you wake up at 3am, why you sweat in bed, and the frozen water bottle hack that works better than most expensive sleep gadgets

 • Why dreams are emotional metabolism, how recurrent nightmares are linked to a 100% increase in suicidality, and the daytime therapy Dr. Breus is developing to help veterans process trauma through their dreams

Take the chronotype quiz and find out if you're a lion, bear, wolf, or dolphin before you listen.

There is a 45% chance the fish oil sitting in your cabinet right now is already oxidized. And rancid omega-3s do not just fail to help you. Research shows they generate pro-inflammatory byproducts that work against everything you are taking fish oil for.

Dr. G breaks down exactly how this happens, how to test what is in your cabinet tonight with zero equipment, and what to actually look for before you buy another bottle.

In this episode, you will learn:

 • The two oxidation markers most brands count on you never knowing about, the peroxide value and the anisidin value, and the total oxidation score that tells you whether your fish oil is actually fresh

 • Why the number on the front of your fish oil bottle is not the amount of omega-3s you are getting, and the simple math that reveals whether you have been underdosing for years

 • The at-home test you can do right now with one capsule, a pin, and 30 seconds that will tell you immediately whether to keep your fish oil or throw it away

Plus the specific brands that passed Dr. G's independent investigation for certificate of analysis standards, packaging, storage, meaningful EPA and DHA doses, and proper oxidation scores.

Episode Description

You've been using alcohol, hydrogen peroxide, and Neosporin your whole life. And none of them are actually helping you heal faster. In fact, they may be slowing you down.

Justin Gardner is the founder of Active Skin Repair, a medical grade hypochlorous acid product that was originally developed for hospital use in burn units, wound care centers, and neonatal ICUs before he licensed it and brought it to the public. Dr. G has been using it since 2019, including once when he cut his finger open deep in the mountains of Tanga and used it instead of stitches. Eight days later it was nearly sealed. Three weeks later, no scar.

In this episode, you'll discover:

 • What hypochlorous acid actually is, why your white blood cells already produce it, and why it kills 99.9% of bacteria, fungi, and viruses within 15 seconds with the same safety profile as saline solution

 • Why alcohol and hydrogen peroxide kill the healthy growth factors your body produces to heal itself, and how hypochlorous acid cleans the wound without impairing the repair process

 • How parents, kids, pets, athletes, and anyone dealing with acne, eczema, sunburns, diaper rash, or chronic wounds can use one bottle for almost everything

This is the Windex of skin care. In the best possible way.

Episode Description

In 2025, researchers published what may be the most important longevity study of the decade. Three years. Over 2,000 participants. A randomized controlled trial. And the results stopped the researchers themselves.

A 61% reduction in invasive cancer risk. A 39% reduction in becoming physically frail. And measurable slowing of biological aging, verified by epigenetic clocks, the most sophisticated tool science has for measuring how fast your cells are actually aging. These were not elite athletes. They were regular older adults. And the three things that produced these results are inexpensive, accessible, and available at any supplement store.

Most people are either missing them entirely or doing them in a way that produces almost no benefit. Dr. G breaks down exactly what the study found and what you need to do with it.

In this episode, you'll learn:

 • Why omega-3 deficiency carries a mortality risk comparable to smoking, and the specific EPA and DHA dose that the research shows actually slows biological aging at the cellular level

 • Why vitamin D is not optional if you exercise, and why low vitamin D means the training you are already doing is producing a fraction of the benefit it should

 • Why the combination of all three produces results that are not additive but multiplicative, and what that means for anyone over 40 who wants to change their biological trajectory

The window that matters most is not when you are 60. It is now.

Episode Description

The way you show up in relationships today was decided before you even knew how to speak.

Eli Harwood is a licensed therapist, the creator of Attachment Nerd, and the author of How to Deal with Your (Anxiety, Anger, Self-Doubt, Insecurity, Trauma) So Your Kids Don't Have To. She spent nearly 20 years sitting with families watching parents who desperately wanted better for their children but had no roadmap for how to actually get there. This conversation goes deep into why 50% of us never experienced secure attachment, what that did to our sense of self, and what it actually takes to break the cycle before it passes to the next generation.

In this episode, you'll discover:

 • Why chaos can feel more like home than safety, and why the people who confuse you are often more magnetic than the people who make you feel secure

 • What happens developmentally when a child grows up in an unpredictable home and how that wound silently shapes every relationship, every breakup, and every parenting moment that follows

 • The difference between intellectually knowing this work and actually doing it, and why your kids will find every unhealed part of you no matter what

This one is for every parent, every soon to be parent, and every adult who is still trying to figure out why love feels so complicated.
