Dr. Wang Lei
It is appropriate for a seven-year-old child to supplement 400–800 units of vitamin D daily. Excessive or improper use may lead to toxicity. Under normal circumstances, vitamin D promotes calcium absorption in the intestines and facilitates calcium deposition in the bones. In addition to taking vitamin supplements, children should also get more sun exposure, as 70%–80% of the body's required vitamin D comes from sunlight.
