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.

I Take NAD+ Daily at 41 — Here Is the Form and Dose That Actually Works | Heal Thy Self w/ Dr. G #492

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.

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.
