Vitamin AD supplementation is recommended for newborns after birth, and as many moms and dads know, babies are supplemented with vitamin D after birth, at a dose of 400 IU per day. However, vitamin A deficiency, as far as China is concerned, is still relatively widespread. Vitamin A is extremely important for the baby’s eyes, skin and growth and development. First of all, night blindness is also caused by vitamin A. Secondly, vitamin A deficiency can lead to skin problems such as dry skin. Most importantly is long bone development, which also requires vitamin A. Therefore, from a medical point of view, it is recommended that newborn babies take vitamin AD supplements in the dose that is best for them after birth.
