500 mg · NAD+ precursor
Nicotinamide riboside chloride
- WHAT IT IS
- A form of vitamin B3 and a direct precursor of NAD+. The chloride salt is the stable form used in clinical research.
- WHAT IT DOES
- After absorption, cells convert NR into NAD+, supporting the process that turns food into ATP.[3]
- WHY 500 MG
- Randomized trials in adults have used 500 to 1,000 mg per day and shown a reliable increase in blood NAD+ metabolites.[1][2]
- ROLE IN THE STACK
- The lead ingredient. Everything else supports the systems NAD+ feeds into.
