What the evidence supports: BPH symptoms — larger trials found little over placebo.

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

Ongoing use is common in BPH, with monitoring.

Men with benign prostate enlargement — after a proper diagnosis, not instead of one.
