Patient One Phytosterol Complex supplies plant sterols to promote healthy heart and prostate function. Beta-sitosterol, the most abundant plant sterols, also contains Campesterol and Stigmasterol for additional health benefits. Phytosterols are sterol molecules, structurally similar to cholesterol, which are synthesized by plants and are naturally found in grains, nuts, seeds, fruits and vegetable oils. Typical Western diets provide a low amount of phytosterols--only about 100-200 mg per day (based on beta sitosterol content), in sharp contrast to vegetarian and Japanese diets that contain 345 and 400 mg/day, respectively. Further, natural phytosterols are often removed from vegetable oils during processing, pointing toward supplementation as an effective way to receive these healthy molecules.
