Calcium: between necessity and danger
Calcium is an abundant mineral in the human body, essential for proper muscle, heart, and nerve function, as well as for strong bones. With age, bone loss accelerates, especially in menopausal women, increasing the risk of fractures and osteoporosis. Many people then believe that taking calcium supplements is the obvious solution.Biology
Disputed profits
While the importance of calcium for bone health is well established, evidence for the effectiveness of supplements in preventing fractures remains limited. Some meta-analyses have observed a reduction in fracture risk, but the most rigorous studies have not confirmed this benefit. Therefore, the usefulness of supplements remains uncertain.
