Ideal for men over 40, and great for all ages, Saw Palmetto is one of the oldest herbal remedies used for thousands of years for prostate health support. Potent phytonutrients in the berries may help maintain healthy prostate function and normal urinary flow and frequency for day or overnight support. Solaray Guaranteed Potency Saw Palmetto Berry Extract provides 160 mg of berry extract, standardized to contain 85% fatty acids and plant sterols. These powerful nutrients—particularly beta- sitosterol—have been studied for their beneficial role in prostate health and urinary tract support. In addition, saw palmetto may help support healthy hair in a man as he ages. Like all Solaray products, Saw Palmetto Berry Extract is rigorously tested and lab verified for purity and potency.
