NAD+ is a coenzyme present in every cell of the body. It is essential for mitochondrial function, DNA repair, and the regulation of cellular aging via the sirtuin and PARP pathways. Levels decline measurably with age.

Use

Mitochondrial support. Energy metabolism. Anti-aging protocols. Cognitive performance. Recovery from physical and metabolic stress.

Route

Intravenous infusion for therapeutic dosing. Oral precursors (NMN, NR) for daily support. Subcutaneous and intranasal forms exist but are less common clinically.

Pairs with

MOTS-c for mitochondrial biogenesis. Methylene blue for cognitive applications. Glutathione infusion stack.

Status

FDA-approved as a supplement. Clinical IV protocols are off-label.
