Beta-sitosterol

Tier 2 — promising · Prostate · Cholesterol

A plant sterol found naturally in saw palmetto and many other plants. A Cochrane review found it modestly improves urinary symptoms in men with enlarged prostate. Also lowers bad cholesterol by blocking cholesterol absorption in the gut. Generally well tolerated with a good safety profile. May reduce absorption of some fat-soluble vitamins.

Dose: 60–130 mg/day for prostate; 2,000 mg/day plant sterols for cholesterol
