The Active Ingredient Is: Beta-Sitosterol

Beta-Sitosterol is a plant sterol that occurs naturally in plants and contributes to a phytosterol complex used to support normal physiological processes related to cholesterol management.

This formulation is plant-based and derived from natural plant sources, incorporating beta-sitosterol alongside other phytosterols to support its role in the body's handling of dietary fats.

What Does Beta-Sitosterol Do?

Beta-Sitosterol helps maintain normal cholesterol balance by supporting the normal processing of dietary cholesterol in the digestive system.

It aids in reducing the amount of cholesterol absorbed into the bloodstream by competing with cholesterol during digestion, contributing to cholesterol management when part of a balanced diet.

Dietary supplements are not a replacement for a balanced diet. Do not take more than the recommended amount. Keep in a cool, dry area away from light and heat. Ensure they are out of children's reach and view.
