  • The benefits of glutathione (GSH) are inarguable with almost 160,000 research studies as of January 2021. The second most studied antioxidant is Vitamin C with around 67,000.
  • Riboceine was developed by 9 Ph.D.’s led by Herbert T Nagasawa Ph.D.  the Senior Editor of the Journal of Medicinal Chemistry for 32 years and the head of the research facilities at the University of Minnesota and the V.A. for 37 years.
  • There are 37 research studies in PubMed currently with others underway.
  • In a mice study, Riboceine was shown to be 300% more effective than n-acetylcysteine without the Acetylcysteine (Oral Route) Side Effects – Mayo Clinic associated with doses over 750 mg.
  • In another mice study, the control group was normal. The other group was under oxidative stress.  That group only lived half as long as the control group.  Glutathione enhancement reduces oxidative stress and slows down the aging process.
