I had a pretty significant vitamin B deficiency causing megaloblastic anemia and required shots weekly for several months...Also, I have had
problems with highs and lows of calcium, iron, and magnesium...I had a hair analysis done which revealed no heavy metal toxicities, but a deficiency in molybnium (? sp), copper, and nickle...and of course, low ferritin (showed in blood tests too)...My doc believes I have a borderline malabsorption problem and a low intrinsic factor...Something inherited...
