Calcium![]() |
||||
Calcium is needed for the growth and maintenance of strong bones and teeth.
Adequate amounts of calcium are needed throughout life, but the mineral is particularly important during periods of growth, such as childhood, pregnancy, and breastfeeding.
The bones continually lose and gain calcium; however, when loss exceeds gain, the bones become weaker and are more likely to fracture.
Prolonged poor intake of calcium leads to calcium loss from bone, which can cause osteoporosis (brittle bones).
Calcium also is needed for normal blood clotting, blood pressure, muscle contraction, and nerve transmission, and for the functioning of several enzymes and hormones.
