Principal Proposed Uses
- Raising Glutathione Levels
Whey is one of the two major classes of protein in milk. (The other is casein, the “curds” of “curds and whey.”) Proteins are made of amino acids, and whey contains high levels of the amino acid cysteine. This is the basis for many of its proposed uses. It also contains branched chain amino acids ( BCAAs ). However, while there is no question that whey is a highly digestible and rich protein source, there is no meaningful supporting evidence that it provides any specific health benefits.
When milk is converted into cheese, whey is the liquid that is left behind. There is no specific dietary requirement for whey, as the amino acids it contains are present in a wide variety of other foods, as well.
There are no well-documented medicinal uses of whey protein.
However, while these are promising findings, one essential piece of evidence is lacking: there is no evidence as yet that this rise in glutathione produces any meaningful health benefits.
