Calcium acts as an important intracellular signal in the neurons and glia of the nervous system, being used everywhere in the body to regulate muscle contractions, including and especially heart function, regulate hormones and enzymes, and support blood vessel function. The body cannot produce calcium on its own, in fact, the body will take calcium from the bones if calcium is needed elsewhere, leading to weaker and more brittle bones prone to fracture. Attaining peak bone mass for young adults and reducing the risk of developing osteoporosis, therefore, is especially reliant on proper calcium levels during bone development.

According to research, women (amenorrheic, the female athlete triad and postmenopausal), people with dairy allergies or lactose intolerance, poor dietary intake groups (adolescents and the elderly) are the three populations at high risk of calcium deficiency.
