EP. 195: I’m so excited to have Dr. Greg Kelly back on the show! He’s a leading expert in longevity and regenerative medicine, and today, we’re diving deep into NAD+—one of the most important molecules for energy production and aging.  In this episode, we break down what NAD is, why it declines as we age, and how we can support our natural levels to look and feel our best. We also get into the science behind the Krebs cycle, the gut microbiome, and how factors like B vitamins, circadian rhythm, and even coffee play a role in NAD+ production.  Episode Highlights:   What NAD+ is and why it’s essential for energy and aging   How NAD+ levels decline over time and signs you might be low   How vitamin deficiencies impact aging, mood, and energy   The connection between the gut microbiome and NAD+   The impact of circadian rhythm, red light, and exercise on NAD+   Sponsored By: Qualia Go to qualialife.com/DRTYNA and use code DRTYNA at checkout for up to 15% off your purchase.
