LW-NAD+ Buffer 500MG

Description

• NAD+  Nicotinamide Adenine Dinucleotide

NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme present in all living cells, serving as a critical electron carrier in metabolic redox reactions. As a central molecule in cellular energy production, DNA repair, and epigenetic regulation, NAD+ has become a focal point of longevity and mitochondrial research.

• Biological Significance

NAD+ participates in over 500 enzymatic reactions and serves as a substrate for three major enzyme families: sirtuins (SIRT1-7), poly-ADP-ribose polymerases (PARPs), and cyclic ADP-ribose synthases (CD38/CD157). Sirtuin activation through NAD+ availability regulates mitochondrial biogenesis, oxidative stress defense, and inflammatory gene expression. Age-related NAD+ decline is associated with diminished mitochondrial function and altered cellular homeostasis.
