Harvard Doctor reveals #1 Cause of Aging You've Never Heard Of | Dr. Andrew Salzman
What if aging isn’t simply your body “wearing out”… but your body losing the ability to repair itself? In this episode, Dr. Andrew Salzman joins Dr. Josh Axe to explain why chronic inflammation, leaky gut, and depleted NAD may quietly drain the very energy your cells need to heal, think, move, and survive.
