Very simply, Immunocal is a bonded cysteine delivery system.
The three amino acids that your body requires to make glutathione in the cells are cysteine, glutamine or glutamic acid, and glycine.
Of these three, the one most difficult to obtain from our diet is cysteine. The other two are quite plentiful and easily obtained from our standard diet.
Immunocal provides cysteine in a protected (bonded) form so it doesn't get destroyed in the digestive tract. It safely travels to the cells where it enters, splits, and combines with the other two plentiful amino acids to make glutathione in the cell.
