Proferrin® Lactoferrin

A patented native lactoferrin, highly purified, derived from milk.

Proferrin® is a highly purified lactoferrin, obtained from milk using a manufacturing process that preserves the structure of the protein. Lactoferrin is a glycoprotein naturally found in colostrum, breast milk and several of the body’s secretions.

It owes its name to its most remarkable property: a strong natural affinity for iron. It is one of the most studied milk proteins in scientific research.

In Europe, lactoferrin has no authorised health claim. So we present it for what it is: a pure, patented, traceable and precisely dosed ingredient.

What we know about lactoferrin

A milk glycoprotein

Lactoferrin belongs to the transferrin family, proteins that can bind iron. It is found in high concentrations in colostrum, the first breast milk.

A natural affinity for iron

Each lactoferrin molecule can bind iron ions. This biochemical property explains the interest researchers take in it.

An active field of research

Lactoferrin is the subject of numerous international scientific publications, including studies in humans. This research does not constitute an authorised health claim for a food supplement.
