What the evidence supports: hangover symptoms — largely extrapolated from animal studies.
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
Occasional, situational use. There is no basis for taking it daily.
Who it's actually for
People looking to reduce hangover symptoms — with the caveat that the evidence is mostly animal studies.
Safe upper limit
Unverified
No formal limit; 300–600 mg is typical. Human safety data is limited
Short-term use appears well tolerated, but there is no long-term safety data and no established limit.
