It is an antioxidant made from amino acids called glycine, cysteine, and glutamic acid
The effect of N(G)-nitro-L-arginine methyl ester and L-arginine
The catch is that oral glutathione supplements almost always break down in the stomach before absorption
While GHK-Cu is ineffective orally by itself due to its vulnerability to stomach acid and proteolytic enzymes, this formulation effectively shields the peptide, ensuring high absorption rates
GSTs are able to conjugate glutathione (-l-glutamyl-l-cysteinyl-glycine, GSH) to a wide range of hydrophobic and electrophilic molecules including many carcinogens, therapeutic drugs, and many products of oxidative metabolism, making them less toxic and predisposed to further modification for discharge from the cell (Fig
