Saw palmetto has been utilized for decades to support healthy prostate and urinary function. In countries like New Zealand, France, Germany, and Austria, this herb has been the gold standard for prostate support for many years. Its primary mode of action involves supporting healthy testosterone metabolism, in part by maintaining healthy 5-alpha-reductase enzyme activity and receptor binding. In a recently published JAMA meta-analysis involving 18 randomized controlled trials and almost 3,000 men, results suggest that saw palmetto provides important urologic support by promoting healthy urinary function. In a three-year German study, saw palmetto extract promoted healthy urinary function in volunteers.
