The evidence in words
The verdict
For physical / metabolic function, Nicotinamide Riboside earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Inconsistent
How it might work
It is converted to NAD+, aiming to restore the age-related decline in this central coenzyme.
How to use it
300–1,000 mg/day.
Safety & cautions
Well tolerated in trials to a year.
Bottom line
The most-vetted NAD+ booster for safety, but the clinical payoff still hasn't shown up. Fine to trial, don't expect miracles.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
- 300–1,000 mg/day.
