Beta-sitosterol & Cholesterol Levels
-
Sources
-
Soybeans, rice bran, wheat germ and corn oils contain highly concentrated levels of the white, waxy substance called beta-sitosterol. This natural compound is also found in fruits, vegetables and nuts.
Function
-
Beta-sitosterol is commonly used to minimize cholesterol intake. "When consumed with cholesterol, it effectively blocks cholesterol's absorption, resulting in lower serum cholesterol levels," says Dr. Michael Lam, a specialist in nutritional medicine.
Effects
-
The human body fails to process beta-sitosterol efficiently. This is beneficial to reducing cholesterol intake as cholesterol binds to beta-sitosterol, and the two substances move quickly through the digestive system toward excretion.
Dosage
-
Physicians commonly suggest dietary supplementation. "Between 500 mg and 10 grams of beta-sitosterol per day have been used in clinical research to reduce elevated blood cholesterol levels," reports the University of Michigan Health System.
Warning
-
Commonly taken in pill or liquid form, side effects of beta-sitosterol may include diarrhea, constipation, gas, nausea or indigestion.
