What it is
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.
