Nicotinamide Adenine Dinucleotide · Injectable Form
Nicotinamide adenine dinucleotide. Studied in sirtuin activation and DNA repair.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells, essential for mitochondrial energy production (ATP synthesis), sirtuin-mediated DNA repair, and PARP-dependent genome maintenance. NAD+ levels decline approximately 50% between ages 40 and 60. Clinical research by Yoshino et al. (Cell Metabolism, 2018) demonstrated NAD+ restoration improves insulin sensitivity in postmenopausal women.
Store lyophilized at -20°C. Light-sensitive — protect from UV exposure. Reconstituted: 2–8°C, use within 2–3 weeks.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell and the central electron carrier of metabolism. Turning nutrients into ATP through the Krebs cycle and oxidative phosphorylation requires it at every step.
It is also the required substrate for sirtuins (SIRT1-7) and PARPs, enzyme families linked to DNA repair and cellular ageing. Published research reports tissue NAD+ levels falling by 50% or more between ages 20 and 60, which is why it is widely studied in longevity research.
