What is Beta Sitosterol?

Beta sitosterol, also known as plant sterol or phytosterol, is one of several steroid-like alcohols and phytochemicals that occur naturally in many plants. The cholesterol-like compound is found in many foods such as rice bran, wheat germ, corn oil, fruits, vegetables, nuts and seeds.

Plant sterols support a healthy cardiovascular system and aid the immune system.

Health Benefits of Beta Sitosterol

Beta sitosterol supports healthy cholesterol levels by regulating cholesterol absorption by the intestines.

Beta sitosterol is added to some margarines and foods that are designed for use in a cholesterol-lowering and/or heart disease prevention diet. The U.S. Food and Drug Administration (FDA) permits manufacturers to state that foods containing plant sterol esters such as beta sitosterol reduce the risk of coronary heart disease (CHD) as part of a diet low in saturated fat.

Purity and Concentration of Beta Sitosterol

Beta sitosterol 40% is a vegetarian and vegan product assayed by the manufacturer to be greater than 40% beta sitosterol and 90% phytosterol. It is extracted from soy beans.

Potential Side Effects of Beta Sitosterol

Beta sitosterol is safe for general use. Although most people don't experience adverse side effects, ingesting more than the recommended dose may cause stomach upset, nausea, diarrhea, gas or constipation. Using beta sitosterol is not advisable for people with sitosterolemia (a rare inherited fat storage disease), as this condition already increases beta-sitosterol levels.

Suggested Use of Beta Sitosterol

The suggested serving size for beta sitosterol is 1000 milligrams once or twice a day, before meals or as directed by a physician. A 5/8 teaspoon, or a rounded 1/2 teaspoon, will yield the desired amount. You can see the full bulk density/volumetric conversion chart for Beta Sitosterol here.
