To the AC with MS and to Fraeguile,
There is research out there that suggests you should NOT be taking Vit.D if you have an autoimmune disease! Please google the "Marshall Protocol". My son has a Vit.D3 level of 10 and Hashimotos. He was told by an endocrinologist to stay away from this vitamin. I believe the theory is that it revs up the immune system and by doing so it can exacerbate the immune attacks. I honestly don't know what to believe, but you may want to check it out.
