Does Dairy Affect Lactoferrin?

May affect absorption or how you feel

The short answer

While lactoferrin is naturally found in milk, supplemental lactoferrin competes with casein for iron binding. Taking with dairy reduces its iron-chelating therapeutic effect.

How to arrange timing

Take lactoferrin supplements on an empty stomach, at least 1 hour from dairy.
