Saw Palmetto

How well does saw palmetto work?

Saw palmetto is most often used for symptoms of an enlarged prostate (BPH). Experts disagree on whether saw palmetto improves symptoms of BPH.

Is saw palmetto safe?

Few problems have been reported among men taking saw palmetto. But some people may experience stomach problems.

Men who have problems urinating should see a doctor to rule out prostate cancer. Prostate cancer is treatable, but treatment may be more successful when you find and treat the cancer as early as possible.

The U.S. Food and Drug Administration (FDA) does not regulate dietary supplements in the same way it regulates medicines. A dietary supplement can be sold with limited or no research on how well it works.

Always tell your doctor if you are using a dietary supplement or if you are thinking about combining a dietary supplement with your conventional medical treatment. It may not be safe to forgo your conventional medical treatment and rely only on a dietary supplement.

When using dietary supplements, keep in mind the following:

  • Like conventional medicines, dietary supplements may cause side effects, trigger allergic reactions, or interact with prescription and nonprescription medicines or other supplements you might be taking. A side effect or interaction with another medicine or supplement may make other health conditions worse.
  • Dietary supplements may not be standardized in their manufacturing. This means that how well they work or any side effects they cause may differ among brands or even within different lots of the same brand. The form you buy in health food or grocery stores may not be the same as the form used in research.
  • The long-term effects of most dietary supplements, other than vitamins and minerals, are not known. Many dietary supplements are not used long-term.
