Can You Take Beta-Sitosterol and Plant Sterol Esters Together?

Use extra care with this pair

The short answer

Beta-Sitosterol is a primary component of Plant Sterol Ester blends. Taking both stacks identical compounds, which may exceed recommended phytosterol intake ranges and impair fat-soluble vitamin absorption.

How to arrange timing

Do not combine Beta-Sitosterol with Plant Sterol Esters. Choose one plant sterol formulation to avoid excessive intake.
