The overall top food for maximizing your glutathione is high quality whey protein. Our Organic Whey is high in glutathione pre-cursors. While whey protein itself does not contain "glutathione," it does contain the ingredients your body needs to maximize it.
All whey is not created equal. It must be cold pressed whey protein derived from grass fed cows, and free of hormones, chemicals and sugar.
Quality whey provides all the key amino acids for glutathione production (cysteine, glycine and glutamate) and contains a unique cysteine residue (glutamylcysteine) that is highly bioactive in its affinity for converting to glutathione.
Glutamylcysteine is a bonded cysteine molecule (cysteine plus glutamate) that naturally occurs in Bovine Serum Albumin - a fragile immune component of the whey. This unique cysteine is exclusive to whey and rarely appears in other protein foods - which makes whey protein the best glutathione-promoting food source.
Furthermore, whey provides critical co-factors, immunoglobulins, lactoferrin and alpha Lactalbumin (also a great source of cysteine), which together help create the right metabolic environment for high glutathione activity.
