钙是人体最重要的矿物元素,是构建骨骼和牙齿并维持其健康必不可少的物质。骨骼的强壮程度间接取决于钙及其他矿物质的吸收,如磷和镁。钙对神经传导、肌肉收缩(包括心肌收缩形成心跳)、细胞分裂也起着重要的作用。 Calcium is the body’s most important mineral element and is an essential substance for building bones and teeth and maintaining its health. The strength of bones indirectly depends on the absorption of calcium and other minerals, such as phosphorus and magnesium. Calcium on nerve conduction, muscle contraction (including contraction of the heart to form a heartbeat), cell division also plays an important role.
