- What are prostate supplements? Two popular supplements for treating the symptoms of benign prostate hyperplasia (BPH) are saw palmetto and beta-sitosterol -- a compound derived from saw palmetto as well as other plants (see What It Is).
- Health benefits of beta-sitosterol: Beta-sitosterol has been found in most, but not all studies, to significantly improve perceived symptoms of BPH and urine rate flow (see Beta-Sitosterol — What It Does). Doses used in clinical studies range from 30 mg to 91 mg daily (see Beta-Sitosterol — What to Consider When Buying).
- Health benefits of saw palmetto: The evidence for saw palmetto is less impressive. It may, at best, modestly improve certain urinary symptoms and help to shrink the inner lining of the prostate, but it does not decrease its overall size. A typical dose is 320 mg per day of extract standardized to 85% to 95% fatty acids (see Saw Palmetto -- What to Consider When Buying).
- What did CL's tests of prostate supplements find? ConsumerLab.com's tests identified a number of saw palmetto and beta-sitosterol supplements that contained the generally recommended amounts of these ingredients. However, one saw palmetto product was found to contain fewer fatty acids than expected, and two saw palmetto/beta-sitosterol combination products were found to be improperly labeled (see What CL Found).
- Best prostate supplements? Among all of the prostate supplements approved for their quality in this Review, ConsumerLab selected a Top Pick that also provided a correct dose and formula for treating symptoms of BPH.
- Prostate supplements safety and side effects: Beta-sitosterol and saw palmetto are generally well tolerated, although some individuals experience nausea or other gastrointestinal symptoms. Be sure to check with a healthcare professional for a proper diagnosis before using, since symptoms of enlarged prostate may signal more serious conditions that require prompt medical treatment (see Concerns and Cautions).
