NAD+ (Buffered)

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that plays a central role in energy metabolism, DNA repair, gene expression regulation, and cell signaling. NAD+ levels decline significantly with age, and research links this decline to age-related metabolic dysfunction. This buffered injectable form provides direct NAD+ supplementation for research into sirtuin activation, PARP enzyme support, and cellular rejuvenation.
