Serenoa repens alone gives little to no benefit for BPH-related LUTS
Based on meta-analysis of 124 RCTs showing 6-12% LDL reduction at standard doses. Conservative effectiveness scale with optimal intake around 2g/day. No significant effects on HDL or triglycerides observed.
Mixed evidence from meta-analyses. Some show significant improvement in maximum urinary flow rate vs placebo, while others show no clinically meaningful improvement. Hexanic lipidosterolic extracts (like Permixon) showed most consistent results. Effectiveness is conservative due to conflicting study outcomes.
