Can You Take Beta-Sitosterol and Vitamin E Together?

May affect absorption

The short answer

Beta-Sitosterol interferes with intestinal lipid absorption including fat-soluble vitamins. Vitamin E absorption may be reduced when taken alongside Beta-Sitosterol due to competition for micelle incorporation.

How to arrange timing

Take Beta-Sitosterol and Vitamin E at different times of day, separated by at least 2 hours.

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.
