CALCIUM
Calcium is the most abundant mineral in the body. Most of it is stored
in the bones. The body can't manufacture calcium, so all of it must come
from the diet. If you don't consume enough calcium, your body simply pulls
it from your bones to help meet these needs.
According to the USDA, 3 out of 4 people do not get the recommended
Daily Value of calcium (USDA data, 1994-1996).
