What the evidence supports: menopausal hot flushes — reviews find little consistent benefit.
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
Up to about 12 months in trials; reassess regularly.

Safe upper limit
Unverified
No formal upper limit; 40–80 mg isoflavones daily in trials
