The reason children do not grow taller despite calcium supplementation is

Possible reasons for insignificant height growth in children after calcium supplementation may include the following: 1. Genetic factors: Height is significantly influenced by genetics; short stature of parents may limit a child's height potential. 2. Calcium absorption and utilization: Even with calcium supplementation, poor absorption or utilization—such as due to insufficient vitamin D, which promotes calcium absorption—can reduce the effectiveness of supplementation. 3. Deficiency of other nutrients: Height growth depends not only on calcium but also requires support from various other nutrients, including protein, vitamin D, zinc, and more. 4. Health conditions: Chronic diseases, digestive system disorders, thyroid problems, or other medical issues may impair normal height development. 5. Physical activity and sleep: Lack of adequate exercise and poor sleep quality can also negatively affect normal growth and development.
