How it works

Plays a central role in mitochondrial energy production and cellular repair processes.

Overview

NAD+ is essential for energy metabolism and cellular repair, and levels naturally decline with age. While direct supplementation is limited in effectiveness due to bioavailability, precursors such as NMN or NR are often used instead. Its cognitive relevance is tied to mitochondrial function and long-term brain health rather than acute performance enhancement.
