How does whey protein compare to other protein sources?
Whey Protein is a high quality Complete Protein containing all of the essential amino acids required by the body each and every day. This is based upon several different methods that are used today to evaluate protein quality. No matter which method is used, whey proteins have been proven to be an excellent, pure source of protein! Whey proteins have a Protein Digestibility Corrected Amino Acid Score (PDCAAS) of 1.14. The reported score is 1.0, which is the maximum value allowed by the USDA for reporting purposes. The PDCAAS is the USDA s officially approved method of scoring protein quality. Another method used to measure protein quality is the Protein Efficiency Ratio (PER). Whey proteins have a PER of 3.2, making it one of the highest single source proteins. The PER rating is based upon the evaluation of the growth of animals consuming a fixed amount of dietary protein from a single source. As the PER increases, so does the quality of the protein.
