Biological Value (BV) Definition

Definition: The Biological Value (BV) of a Protein is a value that measures how well the body can absorb and utilize a protein. The higher the Biological Value of the protein you use, the more nitrogen your body can absorb, use, and retain. As a result, proteins with the highest BV promote the most lean muscle gains. Whey protein has the highest BV value, rating as a 104. Egg protein is only second to whey rating as a 100 with milk proteins being a close third rating as 91. Beef rates as an 80 with soy proteins a distant 74. Bean proteins, due to the fact that are plant-based proteins, only rate a 49.
