- Low evidence4 studies
Across 4 studies examining saw palmetto for improving lower urinary tract symptoms (LUTS), 3 reported beneficial effects (mostly moderate in size) and 1 reported a neutral effect; 3 of the 4 findings were statistically significant. The only study reporting an explicit dose used 320 mg/day over 365 days, and the sole study specifying duration showed benefits beginning as early as Month 3. One high-quality RCT in treatment-naïve men with moderate-to-severe LUTS and enlarged prostate found that a saw palmetto extract combined with alfuzosin was significantly more effective than alfuzosin alone, while three reviews provided supporting or mixed evidence.
