NAD (full name: Nicotinamide Adenine Dinucleotide) is a core coenzyme that is essential and abundantly present in the human body and all living cells. In its core form, it exists as oxidized NAD⁺ and reduced NADH, and is involved in hundreds of biochemical reactions such as energy metabolism, DNA repair, and aging regulation.

The core carrier of energy metabolism (energy production)
As a key coenzyme of the electron transport chain, it connects the tricarboxylic acid cycle with the mitochondrial respiratory chain, transferring the hydrogen/electrons produced by the breakdown of sugar, fat, and protein to the respiratory chain to drive ATP synthesis (the currency of cellular energy).
It participates in the three core energy-producing processes of glycolysis, the tricarboxylic acid cycle, and oxidative , and without NAD⁺, cells will rapidly die.
DNA repair and genomic stability (protecting the nucleus)
It is a necessary substrate for **PARP (DNA repair enzyme)**. PARP relies on NAD⁺ to repair single-strand and double-strand DNA damage, maintaining genomic stability and inhibiting mutations.
Activating Sirtuins (longevity proteins), regulating DNA repair, telomere protection, and chromosome stability.
Anti-aging and longevity regulation (anti-aging)
The decline in NAD⁺ levels with age is one of the core indicators of cellular aging and functional decline.
Activating Sirtuins, regulating aging-related genes, delaying cellular aging, and extending healthy lifespan (animal experiments can extend lifespan by approximately 30%).
Improving mitochondrial function, reducing oxidative stress, and enhancing cell vitality. Metabolic Regulation and Prevention of Chronic Diseases (Stable Metabolism)
Regulating sugar and lipid metabolism: Promoting fat breakdown, inhibiting fat synthesis, improving  sensitivity, and assisting in controlling blood sugar and reducing fat.
Antioxidant stress: NADPH (a derivative of NAD) eliminates free radicals, protects cells from oxidative damage, and reduces the risk of chronic diseases.
Cell signaling and gene expression (signal regulation)

Peptide Storage Guidelines: General Tips

When storing peptides, remember to:
• Store peptide in a cold, dry, dark place
• Avoid repeated freezing and thawing of peptide
• Avoid overexposure to the air
• Avoid light exposure
• Avoid storing peptides in solution long term
• Aliquot peptide according to experimental requirements
