NAD+ (Nicotinamide Adenine Dinucleotide)
What does "Coenzyme/Anti-Aging" mean?
NAD+ is not actually a peptide but a coenzyme - a small molecule that helps enzymes do their jobs. It's found in every living cell and is essential for converting food into energy.
Explained Simply
Every cell in your body is like a tiny factory. NAD+ is like the electricity that powers this factory - without it, nothing works. As you get older, your NAD+ levels drop.
How It Works
NAD+ works in two main ways. First, it shuttles electrons in chemical reactions that convert food to cellular energy. Second, it serves as fuel for enzymes called sirtuins.

Quick Reference
NAD+ (Nicotinamide Adenine Dinucleotide)
NAD+ is a dinucleotide coenzyme essential for cellular energy metabolism. It serves dual functions as a coenzyme in redox reactions and as a substrate for NAD+-consuming enzymes including sirtuins and PARPs.
Key Facts
- •Molecular weight: 663.43 g/mol
- •Essential coenzyme in all cells
- •Declines significantly with age
- •Required for 500+ enzymatic reactions
- •Sirtuin and PARP substrate
Mechanism of Action
Shuttles electrons in redox reactions for ATP production. Serves as fuel for sirtuins (longevity proteins) and PARPs (DNA repair). Levels decline ~50% between ages 40-60, correlating with aging phenotypes.
Research Applications
- Cellular energy metabolism research
- Longevity and aging studies
- DNA repair mechanism research
- Neuroprotection studies
Safety Profile
Essential endogenous molecule. Supplementation generally well-tolerated. IV administration may cause flushing. Buffered formulations improve tolerability.
