Saw Palmetto for Prostate: What 27 Studies Found for BPH
Saw palmetto does not appear to help an enlarged prostate. A 2023 Cochrane review of 27 trials and 4,656 men found little to no difference from placebo in urinary symptoms. The NIH-funded STEP and CAMUS trials found no benefit at 320 mg a day or at three times that dose. It is generally safe and does not change PSA results.
