Almost all (98%) calcium in the body is stored in the bones, and the body uses the bones as a reservoir for, and source of, calcium to maintain calcium homeostasis [1]. For example, a longitudinal cohort study of 1,490 women aged 42 to 52 years at baseline who were followed for 1012 years found that fracture risk was not significantly different in calcium supplement users (some of whom also took vitamin D supplements) and nonusers, even though supplement use was associated with less BMD loss throughout the study period [36]. Levels of ionized (or free) calcium, the biologically active form, in serum are also used to measure calcium status.
