GSH supplements would seem to be the most efficient way to increase cellular levels of GSH because if significant amounts of GSH are absorbed intact and are biologically active and also if the digestion process breaks down additional amounts of the supplemental GSH into its precursorswhich would then be also absorbed and available for recombination into GSHthe inter- and intracellular GSH transport mechanisms would be shifted in favor of increased cellular GSH
