When you take vit D...you become more efficient in absorbing calcium from food. High dose Vit D in the area of 5000 IU or more a day, has some suggestions now, to lower any supplemental calcium to 600mg a day or lower.
Tetany can also come from endocrine problems. Parathyroid tumors can cause it.
True allergy to cow dairy comes from the casein protein in milk.
(not lactose-- lactose intolerance is diarrhea and gas from undigested lactose feeding the organisms in the bowel).
