Lactoferrin is a protein naturally present in the body that occurs in milk (especially colostrum, the first breast milk), saliva, tears, and other bodily fluids. It is a so-called iron-binding glycoprotein, which means it can bind to iron.

Lactoferrin CLN® is a high-quality lactoferrin extract derived from cow's milk. It is purified using advanced processes (with double filtration and gentle drying) and has a purity of over 97 %.

Lactoferrin is most abundant in colostrum, the first breast milk, but it is also found in cow's milk, cheeses, yogurt, and other dairy products, albeit in smaller amounts.

Lactoferrin is derived from cow's milk and is therefore not suitable for vegans. Vegetarians who consume dairy can use this product.
