TLDR USPlus PRO saw palmetto extract improves urinary symptoms and is safe for men.
This study evaluated the efficacy and safety of USPlus PRO saw palmetto extract on lower urinary tract symptoms (LUTS) in 80 males aged 45-80. Over 12 weeks, participants received either the extract or a placebo. Results from 62 participants showed significant improvements in the USPlus PRO group, including reductions in the International Prostate Symptom Score (IPSS) and enhancements in sexual function. Notable improvements were seen in voiding symptoms, incomplete emptying, and weak stream. The extract demonstrated a favorable safety profile, suggesting it may be a beneficial treatment for LUTS.
