NAD+ in the Spotlight: New Insights on Boosting Cellular Resilience
We’re doing a deep dive into NAD, a molecule that has received a lot of attention but still confuses many of us, clinicians included. My guest today is able to unpack the complexities of NAD in a way you’ll find extremely illuminating and useful. I’m excited to have Dr. Greg Kelly Senior Director of Product Development at Qualia, back with us, explaining how NAD is foundational for energy, longevity, and overall cellular health. Dr. Kelly brings clarity to how NAD influences mitochondrial function, DNA repair, and pretty much all of the hallmarks of aging. Yet, problematically, it declines as we age. This episode will cover different NAD compounds, how deficiency might present clinically, and how to measure NAD reliably. Have a listen and get ready to expand your understanding around this essential compound. ~DrKF
