I was also given some --- acid that the liver produces. Can't remember name. However, I would like to suggest that those taking medication check or ask the pharmacy about any interference from Vitamins. The VA provides a list of items not to take with my Paxil. Along with diet aids, I was surprised by some of the vitimins on the list. I know with some heart and blood pressure medications vitimin C and even foods like Grapefruits can render the medication useless. One CVS, Pharmisists suggested I stay away from a multi vitimin Centrum Plus. I find your information great and helpful, and only offer this because of interactions of drugs. Don W
