Thanks bg123, I have been on Magnesium for some time now, but I have colitis, so if I actually absorb much, if any supplements at the moment, I don't really know. I'm working on getting my stomach in the best state possible, I know I had an absorbtion problem last year and was lacking in vitamin B12, which I had to have injections of. It's all a minefield. Thanks for your thoughts. Tracy. <img src="/ubbthreads/images/graemlins/kookoo.gif" alt="" />
