Does Dairy Affect Manganese?

May affect absorption or how you feel

The short answer

Calcium in dairy competes with manganese for shared divalent cation absorption transporters (DMT-1), reducing manganese bioavailability by up to 40%.

How to arrange timing

Take manganese supplements at least 2 hours apart from dairy products.
