How we scored it

Ca3(PO4)2 mineral salt; calcium and phosphate are both natural-origin.
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

Produced from mined phosphate rock and calcium sources, or as a byproduct of mineral processing. No petrochemical route is used.

In plain English
