In this monologue, the speaker emphasizes the importance of the coenzyme NAD+ as a fundamental cellular fuel that powers roughly 500 biochemical processes and accounts for the brain’s high energy demand (up to 30% of total body energy despite being only 3% of body weight). He shares a personal anecdote about his wife's severe depression, chronic fatigue, and excessive caffeine use, linking her symptoms to low cellular energy. The speaker then introduces Genfinity’s supplement Vitality Boost, claiming it can raise NAD+ levels by 200‑300% and describing his regimen of two scoops daily (mixed in 2‑4 oz of water and held on the tongue for 30 seconds). He reports that after 2‑3 weeks of this protocol, he experiences markedly improved mental clarity, stamina, and overall vitality, and he recommends NAD+ supplementation as a core component of health, performance, and longevity optimization.

So one of the most valuable nutrients that hardly anyone talks about at the level it deserves is a nutrient called NAD+. NAD+ is the core cellular fuel for about 500 cellular processes. And when you think through the lens, both of the trauma lens and the peak performance lens, if your cellular energy is deficient, you're not going to be able to perform at your best. You're going to feel like this case of brain fog is just hovering over you and sabotaging your joy and your zest for life. And I saw this firsthand when my wife and I were navigating her depression battle. Where she was sleeping 10 hours a day, 2 naps a day, 400 milligrams of caffeine, and barely functioning. But then we stumbled upon this company called Genfinity, who makes a supplement called Vitality Boost that really catapults your cellular energy or your NAD levels by 200 to 300%, I've seen on average. Because if your cellular energy is in the gutter, guess what? You're just going to feel not great. You're not going to be at your best. And brain function-wise, your brain is 3% of your body weight but uses up to 30% of your body's energy. So, how this works is I I take 2 scoops a day and it's just a little scoop right here in about 2 to 4 ounces of water. I usually just swirl it around and then I let it soak on my tongue for 30 seconds. And what happens in 2 to 3 weeks of taking this twice a day, which means your mental clarity, your stamina, everything, you just feel alive and you feel good. So that's the secret of NAD+. And I highly encourage you include this in a core regimen of optimization for your body, for your health, for your longevity.
