All living organisms use glutathione. Glutathione is what helps organisms survive in an oxygen environment. From bacteria to human beings, glutathione allows an organism to survive better because of the myriad of things that glutathione provides and does for the organism.

If you have a yeast overgrowth, supplying the yeast with extra glutathione may help it survive better. Of course, that is speculation, for no one has done the specific studies necessary to prove it. However, if you are struggling with a yeast problem, eradicate the problem first. There are many yeast-killing formulations, some prescription and some non-prescription, that would be of use to you. What does your doctor suggest?
