Calcium can promote the development of bones and is an indispensable mineral for the human body. Whether or not a child can grow taller by taking calcium tablets depends on whether or not the epiphysis is closed and whether or not the nutrition is sufficient during the growth and development process. If the child is in the stage of growth and development and the epiphysis is not closed, the cartilage can grow further, and calcium can promote the development of bones, so this time to supplement calcium is to help the human body grow taller. If the epiphysis has completely closed, the cartilage will not grow further, calcium supplementation can only help to enhance the strength of the bones, but will not make the human body grow taller. And in the process of growing taller, in addition to supplemental calcium ions, the body also needs protein, fat, vitamins, minerals and other nutrients, so want to grow taller, only by supplemental calcium is not enough. Height is affected by genetics, environment and other aspects, in addition, endocrine diseases, genetic metabolic diseases and other diseases will also affect the growth of height. If you want to grow taller, it is recommended that you take calcium supplements during the growth stage while maintaining adequate nutrition and sleep, and exercising appropriately in order to have good results. Serious height abnormalities require medical attention to identify the cause.
