What the evidence supports: raising NAD levels — which is not the same as a health outcome.
This scores how well-supported the claim above is — not how much benefit you personally would get. A high score on a narrow claim does not extend to everything the product is marketed for.
How long to take it
Unknown. There is no established course because there is no established benefit.
Who it's actually for
People comfortable funding an experiment on themselves.
Safe upper limit
Unverified
No formal limit; 250–1,000 mg daily in trials
Short-term safety looks acceptable. Long-term data does not exist. Regulatory status is in flux.
