While many men can name a variety of herbs commonly recommended for prostate health support, it's likely that few recognize that the benefits come primarily from the phytosterols found within those herbs. One phytosterol in particular, beta-sitosterol, has been correlated with positive prostate health outcomes in scientific research. Our Swanson Beta-Sitosterol features a pine-derived phytosterol extract with 75% beta-sitosterol concentration combined with zinc and selenium, two common nutrients with uncommon benefits for men. While many men's health supplements provide just 60 mg of beta-sitosterol, our high-potency, once-daily formula delivers 320 mg plus high-absorption forms of zinc and selenium for truly powerful prostate nourishment you can trust.
