Promoting calcium absorption is inseparable from vitamin D. I believe everyone understands the importance of calcium nutrition for the body. Vitamin D deficiency is very detrimental to calcium absorption. Poor calcium absorption in babies can seriously affect their growth and development. So, how can babies supplement with vitamin D?
Proper sun exposure is the most effective, convenient, and economical way to supplement vitamin D. Parents should encourage their babies to engage in outdoor activities regularly. In spring and autumn, babies can play directly in the sun. In summer, babies can enjoy shade under trees to expose their skin to UV radiation. UV radiation promotes the chemical conversion of 7-dehydrocholesterol stored in the skin into vitamin D3, which is stored in the skin for future use.
In fact, the vitamin D required by the human body is found in many foods, mainly including sea fish, animal liver, egg yolks, and lean meat. These foods are relatively high in vitamin D. In addition, fish liver oil, skim milk, nuts, cheese, and some seafood are also rich in vitamin D.
Supplementing with vitamin D can also be done orally. Normally, each person needs to supplement 400 milligrams of vitamin D per day, but premature infants or babies with rapid growth should require a higher amount of vitamin D. Generally, these babies can start taking vitamin D from the second half of their life and continue to take it until the age of 3.
