How we scored it
Complete hydrolysate of animal collagen into free amino acids; hydrolysed proteins are 1.0 by rule. 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
