Boosting Glutathione with Whey Protein

There has always been a glutathione-enhancing capability attributed to whey protein in general, and to alpha-lactalbumin in particular. Glutathione (GSH) is a tripeptide composed of cysteine, glutamate, and glycine. It is found inside every single cell in your body where it acts as “the master antioxidant”.

The main function of GSH is to protect your cells and mitochondria from oxidative and peroxidative damage, but it is also an essential factor in energy utilization and detoxification. GSH acts as a general immune system modulator and sufferers of chronic diseases often exhibit reduced glutathione levels. As we age, our body’s ability to produce glutathione decreases. Ironically, glutathione supplements may actually interfere with your body’s own glutathione production. However, enhancing its internal production will strengthen the immune system in a way that will shield you from many of the adverse effects of aging.

In animal studies, whey protein concentrate consistently raised glutathione levels beyond those of any other protein studied, including soy. This is possible based on the intracellular conversion (by alpha-lactalbumin) of the amino acid cysteine to glutathione.
