Saw Palmetto

Also known as: Permixon, Serenoa repens (hair), Saw Palmetto (PCOS Antiandrogen), Saw Palmetto Extract

A
Evidence

Saw palmetto extract is derived from the fruit of Serenoa repens and has been studied primarily for prostate and urinary health support. Evidence suggests modest benefits for benign prostatic hyperplasia (BPH) symptoms, though results are mixed and effects may be modest compared to pharmaceutical alternatives.
