ISO-97 by Caruso Fitness Nutrition is a pure, undenatured whey protein isolate that produces primarily 97% protein on a dry basis when weighed.
ISO-97 is a high-quality protein with a digestibility value of 110 according to the standards of the United Nations Food and Agriculture Organization. In other words, ISO-97 provides 110% of the human body's amino acid requirements. Furthermore, ISO-97 is rich in branched-chain amino acids and has the highest leucine content of any other known protein.
Leucine is an essential amino acid that allows muscles to synthesize proteins. ISO-97 contains no rBST (artificial growth hormone) or GMOs (genetically modified organisms). All the amino acids found in ISO-97 are natural and mix very well with food. ISO-97 is a superior organic whey protein source with unique properties.
This protein powder has a particularly high content of cysteine, an amino acid with very powerful antioxidant properties. Cysteine in the liver produces glutathione in addition to glutamic acid and glycine. It protects cells from environmental toxins, pollution, and heavy metals inside the cells. This product helps keep cells healthy while maintaining the health of the immune system.
