The right answer is Calcium
99% of the calcium is located in the bone, ensuring the skeletal strength and the hardness of the teeth.
In children and adolescents, it promotes bone growth; in young adults, it participates in the maintenance of bone capital; in the elderly, it contributes to the prevention of osteoporosis.
Beside the bone, calcium has other functions like blood coagulation, muscle contraction, nerve conduction, activation of certain enzymes.
Adequate calcium intake - consistent with the recommended dietary intakes - would have a preventive effect against high blood pressure.
