Nad+ Peptide Therapy
Benefits, Side Effects, Cost & Protocols
Nicotinamide adenine dinucleotide (NAD+) is a coenzyme central to metabolism found in all living cells. It plays a key role in cellular energy production, DNA repair, gene expression, and cell signaling. NAD+ levels decline with age, and supplementation is studied for anti-aging and metabolic health benefits.
