Because of the important role "Glutathione" plays as a Master Antioxidant there have been numerous attempts to create oral "Glutathione" supplements. Finally, in 1990 Dr. H. Demopoulos and Dr. M. Seligman, "cracked the "Glutathione" code" and found a way to stabilize "Glutathione" and formulate the first, effective oral supplements. In FDA clinical trials their formulation had a blood cell absorption rate of 75-80%.

This patented formulation, used exclusively in The "Glutathione" Corporation Glutathione products, is the only "Glutathione" formulation to be proven safe and effective in FDA Clinical Trials.

Today, some makers of nutritional supplements are offering generic "Glutathione" supplements. Their formulations have not been tested or proven efficacious and we do not wish to be confused their products. For that reason we market our products under the name Ultrathione^TM. The Ultrathione^TM brand denotes stability, absorbability and pharmaceutical grade of purity.
