Glutathione GSH

Another supplement that has been scientifically proven to increase cellular glutathione levels is undenatured whey protein. Like N-Acetylcysteine, undenatured whey protein contains high levels of digestible cysteine. In other, homogenized whey proteins, the heat involved in the homogenizing process destroys cysteine contained by the whey protein, rendering it useless for the purpose of raising glutathione levels. After homogenization, whey protein is no longer …

First, gamma-glutamylcysteine is synthesized from glutamate and cysteine by the enzyme GCL (glutamate cysteine ligase). This first step is what uses up the cysteine in your body. Next, the amino acid glycine is attached to the gamma-glutamylcysteine by the enzyme glutathione synthetase. Glutathione is not produced by the standard method of cellular protein synthesis because the …
