Many symptoms attributed to aging are also consistent with chronic inflammatory stress and impaired NAD metabolism. Dr. Charles Brenner explains the mechanisms, the human data, and what interventions actually move the needle. He also cuts through the crowded world of NAD boosters, including oral NAD pills, NMN, NR, and NAD IV drips, clarifying what actually raises NAD in humans and what emerging research suggests about NR for lowering inflammation and improving recovery.
