What vitamins do children need to supplement calcium?

*Vitamin C can promote the growth of children's teeth and bones. Children with low immunity may also suffer from vitamin C deficiency. Regular supplementation of vitamin C is very helpful for children's development.

*Vitamin D is critical. Vitamin D in the human body helps the intestines absorb calcium and phosphorus from the diet. On the other hand, it promotes the deposition of calcium and phosphorus in the new bone formation site, promoting the maturation of bone tissue

*Vitamin A can promote protein biosynthesis and help cell proliferation and differentiation. Vitamin A can enhance the cell activity in the epiphyseal cartilage of long bones, promote the differentiation and balance of bone cells, and increase the growth rate of bones.
