The composition of the invention, liposomal glutathione, has been recently shown to have utility for having an antibiotic like effect on Klebsiella pneumonia cultures in vitro, and in vivo as demonstrated by efficacy in reducing by large multiples the presence of cultures of Klebsiella in rats in animal tests. Further, because the liposomal glutathione bolsters body defenses as well as appearing to have direct killing action, the propensity to create more and more resistant strains to antibiotic treatment is downgraded.
