Can You Take Phytosterols and Plant Sterol Esters Together?

Use extra care with this pair

The short answer

Phytosterols and Plant Sterol Esters are the same class of compounds in different forms. Taking both stacks total plant sterol intake, potentially exceeding the 2-3g/day recommended range and excessively impairing fat-soluble vitamin absorption.

How to arrange timing

Do not combine free Phytosterols with Plant Sterol Esters as they are the same active compounds in different forms. Choose one formulation.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
