Health notes
In the U.S., protein isolates are generally recognized as safe (GRAS) by the FDA when used as intended. They are a concentrated source of protein, which is essential for muscle repair and growth. International bodies like JECFA have evaluated protein isolates. Evidence suggests that protein isolates are well-tolerated by most individuals when consumed as part of a balanced diet.
