Pharmacokinetic studies of calcium, iron and zinc show that all three elements are effectively absorbed. Experiments also prove that zinc supplementation can promote the absorption of calcium. The scientific collocation of the three elements can effectively improve the lack of calcium, iron and zinc in human body and meet the needs of the body for the growth and development of calcium, iron and zinc. The therapeutic effects of calcium, iron or zinc supplementation in children are not ideal, because only one of them can not achieve the therapeutic purpose in the case of calcium, iron and zinc deficiency.
