How we scored it

Milk-derived iron-binding glycoprotein; peptides/proteins assembled from natural amino acids are natural origin. 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Lactoferrin is isolated from cow's milk, or whey, a dairy byproduct, by physical separation. As an unmodified milk protein it is fully natural origin.

In plain English

An iron-binding protein naturally found in milk, used to condition hair and skin. It is obtained from milk, an animal source, making it fully natural in origin.
