Beta-sitosterol has shown a number of health benefits for men with BPH looking to restore their prostate health. Beta-sitosterol is a plant-derived, cholesterol-like substance (a phytosterol) found in plants such as saw palmetto, soybeans, and pumpkin seeds, that does not act like cholesterol. In a study of 200 men with BPH who took either beta-sitosterol or placebo for six months, those in the treatment group had “significant improvements” in their BPH symptoms. (Berges 1995) A review of four studies of BPH and beta-sitosterol that included 519 men found that beta-sitosterol improved urinary symptom scores and urinary flow rates while also reducing the volume of residual urine. (Wilt 1999) No standard dose of beta-sitosterol has been established, but 60 to 135 mg daily is typically used to treat BPH symptoms. Read more on beta-sitosterol for BPH
