Oral Glutathione does NOT work
"Oral Glutathione is NOT effective because the stomach enzymes destroy the glutathione. It makes it useless and doesn’t get absorbed by the body. In one of the experiments, a person took 3,000 mg of Oral Glutathione and later blood level glutathione was analyzed. As expected, Glutathione did not show in the blood. Some of the manufacturers of glutathione pills are now trying to put a protective layer in the pills. But even though they do this, not all will be absorbed and so the money you spent for this goes to the drain and you don’t get the desired result. In Intravenous route, however, the most concentrated form flows directly to the blood where it is really desired to go and be distributed to the different parts of the body. Therapeutic effect will last 2-4 months after therapy is discontinued."
