If the new injectable obesity drug is indeed a "game-changer", would you prescribe it?; If l-glutamine is good for gut health but may feed an existing cancer, how do you know how to dose it or prescribe it at all?; What kinds of nutritional support are available for my 12-year-old son with Reynaud's?; I recently had a nuclear stress test. How can I "detox" or mitigate the radiation exposure effects from that?; I get blurry vision from my anti-anxiety meds. Is there anything I can take to combat it?
