Proteins are made of individual amino acid building blocks and the completeness of a protein source quantifies its nutritional value. The method currently used by both the U.S. FDA and the United Nations Food and Agriculture Organization (UN FAO) to measure completeness of a protein is the Protein Digestibility Corrected Amino Acid Score (PDCAAS). A complete protein (PDCAAS of 1) supplies all 11 essential amino acids in their necessary relative amounts. Blending two or more proteins together can boost the completeness of protein in a formulation.
