Whey Protein Isolate has a BV closer to 100, indicating that a large proportion of the protein consumed is absorbed and used by the body for protein synthesis, particularly in muscle repair and growth. This high BV underscores its effectiveness as a protein supplement, making it a superior choice for athletes and individuals seeking to enhance their dietary protein intake for muscle building and recovery.
