How does Beta-sitosterol work?

Beta-sitosterol is a plant substance similar to cholesterol. It might help reduce cholesterol levels by limiting the amount of cholesterol that is able to enter the body. It can also bind to the prostate to help reduce swelling (inflammation).

Are there safety concerns?

Beta-sitosterol is LIKELY SAFE for most people when taken by mouth. It can cause some side effects, such as nausea, indigestion, gas, diarrhea, or constipation. Beta-sitosterol has also been linked to reports of erectile dysfunction (ED) and loss of interest in sex.

Beta-sitosterol is POSSIBLY SAFE when applied to the skin.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of beta-sitosterol during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Sitosterolemia, a rare inherited fat storage disease: People with this condition have too much beta-sitosterol and related fats in their system. They are prone to early heart disease. Taking beta-sitosterol makes this condition worse. Don't take beta-sitosterol if you have sitosterolemia.
