What is happening. High-dose plant sterols can modestly reduce absorption of some fat-soluble dietary compounds; clinically important vitamin D effects are not well proven.
Mechanism. Competition in intestinal lipid micelles is possible at high plant sterol intakes.
Recommendation. Take vitamin D with a meal and monitor 25-hydroxyvitamin D if deficiency is being treated.
