Soy Protein Isolate (SPI) is a concentrated source of high-quality soy protein. SPI supplies the necessary amino acids, including the essential amino acids, to help support muscle growth. In fact, research shows that SPI is just as effective as whey protein for building muscle. SPI provides glutamine and arginine, two amino acids associated with hormone release and immune function. SPI also contains naturally-occurring antioxidants.
