When the level of calcium falls, the parathyroid hormone ensures that calcium is removed
from the bones, that calcium in the urine is reabsorbed, and that calcium in food is ab-
sorbed. When the level of calcium in the blood is too high, calcitonin ensures that calcium
in the bones be retained and that the bones speed up the absorption of calcium.
formula are able to make cells perform two totally different functions, a
wonder that cannot be explained by the operation of evolution.
Now there remains a third thing you must do. You must get the
body to retain more calcium from the food that it consumes.
The mixing of the calcium in the food you eat with the blood occurs
in the small intestine, but in order for the calcium to be reabsorbed, the
intestinal cells need "activated vitamin D." Here, a major problem arises,
because the vitamin D you obtain through your food is inactive. In
