Phytosterols health benefits

  1. Numerous clinical and animal experiments and epidemiological studies have found that phytosterol supplementation has the effect of lowering total blood cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C). At the same time, it does not reduce the levels of high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) and does not have any significant side effects.
  2. A large number of studies have found that phytosterols have a certain significance in reducing the incidence of benign prostatic hypertrophy in men.
  3. Epidemiological studies have shown that dietary intake of phytosterols is negatively associated with the incidence of some cancers such as prostate, ovarian, and stomach cancers.
