Quick answer
Lactoferrin is a protein found naturally in milk, and in especially high amounts in colostrum, the first milk produced after birth. It's called an iron-binding protein because each molecule can hold iron. Supplement lactoferrin is usually made from cow's milk and sold in capsules, such as 500mg per capsule.

Where does lactoferrin come from?
Lactoferrin is naturally present in milk and other body fluids. Colostrum contains much more than regular milk. Commercial lactoferrin is separated from cow's milk or whey and dried into a powder for capsules.
Why is it called "iron-binding"?
Lactoferrin belongs to the transferrin family of proteins, which can bind iron. Its pinkish colour comes from the iron it carries. The name combines "lacto" (milk) and "ferrin" (iron).
