What is glutathione and is it safe to use?

Body's antioxidant: Glutathione is a protein produced by our bodies that is an antioxidant. It plays key roles in clearing toxins and immune function. It is very safe to take though poorly-absorbed unless taken as liposomal or acetyl-L-glutathione. We can also take supplements like N-acetylcysteine, Alpha lipoic acid and milk thistle and eat foods that help our bodies make more of it. See http://tinyurl.com/n2wu2pw
