Does Dairy Affect Collagen?

May affect absorption or how you feel

The short answer

Casein in dairy competes with collagen peptides for intestinal amino acid transporters, potentially reducing collagen absorption.

How to arrange timing

Take collagen supplements at least 1 hour apart from dairy for better absorption.
