How we scored it

Assembled from glycine, proline and alanine (fermentation/hydrolysate amino acids); coupling reagents leave no mass.
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
