Glutathione and cofactors such as selenium help to neutralize and prevent an excess accumulation of hydrogen peroxide in the cell while maintaining an immune benefit.5 Selenium has also been shown to increase lymphocyte proliferation, the activity of helper T cells, cytotoxic T cells and natural killer cells

With reference to human FX, these bonds are formed between the cysteine residues at positions 17 and 22, 50 and 61, 55 and 70, 72 and 81, 89 and 100, 96 and 109, 111 and 124, 132 and 302, 201 and 206, 221 and 237 , 350 and 364, 375 and 403 corresponding to the residues shown in SEQ ID NO: 134 (See Figure 1)

As we age, we lack key amino acids needed to build glutathione, and can suffer from glutathione deficiency
