How we scored it
Naturally occurring soluble collagen protein; amino acids are natural building blocks, no petrochemical fragment.
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

In plain English
A water-soluble form of collagen, a structural protein. Used to help condition skin and hair, form a film, and attract moisture.
