Why Saw Palmetto for Hormones

Saw Palmetto plays a supporting role in hormones. Saw palmetto is the most studied herbal treatment for benign prostatic hyperplasia (BPH). A 2012 Cochrane review (32 RCTs, 5666 men) found evidence for mild improvement in urinary symptoms, though the largest STEP and CAMUS trials (NEJM 2006, 2011) showed no significant benefit over placebo for LUTS at 320 mg/day.

What dose to look for

Clinical studies typically use 160–320 mg of saw palmetto. Standard dose is 320 mg/day of liposterolic extract (85–95% fatty acids). Some studies use 160 mg twice daily. Products below this range may not deliver meaningful results.
