- Beta-sitosterols for benign prostatic hyperplasia
Beta-sitosterol is the plant sterol behind several prostate supplements. It improves BPH urinary symptoms and flow short-term — better evidence than saw palmetto for this use — though the trials are small and dated, and it does not shrink the prostate.
