A closer look
What forms will I see on a label?
Products include berry powders and extracts. Their composition varies, so preparations should not be assumed equivalent.
Why people use it
People use it for prostate and urinary wellness, and sometimes for hair-loss goals.
These are common goals and marketing uses. The evidence section below explains what research supports.
What does the evidence tell us?
Good evidence indicates little or no benefit from saw palmetto alone for urinary symptoms due to an enlarged prostate. Evidence for hair loss remains too limited for firm conclusions.
What should I know before using it?
Digestive symptoms, dizziness or headache can occur. Avoid during pregnancy or breastfeeding. Have new or worsening urinary symptoms assessed rather than relying on a supplement.
