Beta sitosterol is found in a variety of vegetables, grains, nuts, seeds and fruit, with soybeans being a particularly rich source. Scientists are studying the impact that beta sitosterol has on helping the human body support cholesterol levels that are already within a normal range, as well as protecting prostate health.
