Whey Cool™ contains exceptional levels of cysteine, which is the critical precursor for the intracellular production of glutathione. Cysteine is very scarce in our modern diet and therefore glutathione production is limited and deficiency is prevalent. If cysteine undergoes any heating or processing, as most conventional whey products do, it is denatured and converted to cystine which cannot be utilized for efficient glutathione production. Whey Cool™ may help to raise glutathione levels exceptionally well because the cysteine comes naturally bound to glutamine and glycine. This complete protein also contains considerable amounts of the amino acid glutamine, known for its muscle building, gut healing and immune-boosting properties.
