Sublingual glutathione is glutathione (GSH) administered under the tongue so that the glutathione can be absorbed directly into the bloodstream. There is some evidence showing that this may be more effective than taking oral GSH. Oral GSH is destroyed in the gut and is not effective in raising GSH.
Glutathione is a protective protein that has only positive effects in the body, so is sublingual glutathione safe for pregnant mothers and for their unborn baby? It is not only safe, but recommended for both by Dr. Jimmy Gutman, world's leading expert on the subject of glutathione in his latest bestseller "Glutathione - Your Key To Health" in Chapter 18: "Pregnancy, Lactation, and Childbirth."
For more information on this, please see what he has to say about glutathione and pregnancy.
Many find Immunocal to be the most effective and natural way for pregnant mothers to raise their glutathione.
