Hate to stick my oar in Andrea, but I do know that vitamin D can prove to be a very difficult vitamin for many folks, you have to be real carefull with it, could you not get enough from sunlight? I know Dr. Mercola thinks that is the best source and he warns of possible toxicity from the pill form, hard on the liver. I wish I could get a friend of mine to read yours and Sharons posts, there is more good information here than I can remember to tell her...
many thanks
