NAD+

Nicotinamide Adenine Dinucleotide

Also: NAD · Coenzyme I

human trialmeta analysisanimal study

While technically a coenzyme rather than a peptide, NAD+ is included here due to its centrality in the longevity/biohacking community. NAD+ levels decline ~50% between ages 40-60. It's essential for cellular energy production, DNA repair, and sirtuin activation. Supplemented via precursors (NMN, NR) or direct IV/subcutaneous NAD+.

Essential cofactor for redox reactions in mitochondrial energy production. Activates sirtuins (SIRT1-7) — the 'longevity genes' that regulate DNA repair, inflammation, and metabolism. Required substrate for PARP enzymes (DNA repair) and CD38 (immune signaling).
