If a whey protein powder is labeled with a nutrition facts panel and not a supplement facts panel, then it is not subjected to the same quality control tests. Whey proteins that are labeled as a food (nutrition facts) are not required by law to be testing for things such as protein quality and protein grams to verify the label claim. It is a way that companies can cut testing costs primarily, but other costs associated with running a dietary supplement firm as opposed to a food manufacturing firm. If a whey protein is labeled with a supplement facts panel, then by LAW the whey protein supplement must be tested for several quality parameters. Keep this in mind next time you shop for a whey protein!
