Overall, beta-sitosterol, a common ingredient in supplements for prostate health, and, in higher doses, in cholesterol-lowering supplements, appears to be well-tolerated. Rarely, however, erectile dysfunction and loss of libido were reported among 1% of men taking beta-sitosterol to treat prostate enlargement (benign prostatic hyperplasia, or BPH). For more about this, and other potential side effects (as well as side effects of saw palmetto, which is often combined with beta-sitosterol in prostate supplements) see the "Concerns and Cautions" section of the Prostate Supplements Review >>
