What is Saw Palmetto Extract?

Saw palmetto (Serenoa repens) is a small palm native to the southeastern United States, whose berries have been used in traditional medicine for over a century to support prostate and urinary health in men. The standardized extract (containing 85-95% free fatty acids and sterols) mildly inhibits 5-alpha-reductase, the enzyme that converts testosterone into dihydrotestosterone (DHT). DHT drives both benign prostatic enlargement and the androgen-mediated hair loss pattern in genetically susceptible men. Clinical research supports its use for urinary symptoms and is investigated for its mild adjunctive role in male pattern hair loss. Standard dose is 320 mg of standardized extract daily.
