U r right. Oral glutathione hardly works because it will break up in digestion and never get absorb by the body. In the past, medication treatment is via intraveneous.
I've been trying the MaxIntertional's MaxOne for the last few months and I found it very effective. MaxOne contain oral glutathione precursor that is wrap by RiboCeine, a patented technology that protect the precursor from breaking up in the digestion and delivered them direct to the cell (this is what we want - straight to the cell !)
RiboCeine is invented by Dr.Herbert Nagasawa after 35 years of research.
