Heal Thy Self with Dr. G

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.
