Does High-fiber foods Affect Vitamin A?
May affect absorption or how you feel
The short answer
Fiber reduces fat absorption, and vitamin A is fat-soluble. High-fiber meals decrease vitamin A bioavailability.
How to arrange timing
Take vitamin A with a low-fiber meal containing some fat, at least 2 hours from high-fiber foods.
