Top outcomes
60 to 130 mg a day for BPH urinary symptoms, the doses of the two six-month placebo-controlled trials: 20 mg three times a day, and 130 mg of free beta-sitosterol once a day. Both used phytosterol extracts with beta-sitosterol as the main component, so check the label for the beta-sitosterol content. For lowering cholesterol, gram doses of plant sterols or stanols are a different product: see the Plant Sterols & Stanols entry.
