When should babies take vitamin D?

In fact, many trace elements in the human body are related, such as vitamin D and calcium. These two substances have an inseparable relationship. If a person lacks vitamin D, it will directly lead to the loss of calcium. Especially for babies in the critical period of growth and development, lack of vitamin D is likely to lead to developmental problems and rickets. In the process of supplementing vitamin D, about how old is it necessary to supplement it?

There is no clear definition of how long babies should take vitamin D, and it usually depends on the baby's physical condition. If an infant is deficient in vitamin D, it should be supplemented at any time; if the infant has enough vitamin D in his body, there is no need to supplement vitamin D through nutrition. But in general, full-term newborns need to supplement vitamin D from birth to the fifteenth day. Generally, one is vitamin A and D in cod liver oil capsules. 900 capsules and 300 mg per day are enough for the baby.

Vitamin D supplementation is important because it is also key to calcium supplementation, and a lack of vitamin D can lead to calcium loss. Therefore, vitamin D should be used to prevent rickets in babies 2 weeks after birth. According to the relevant provisions of China's maternal and child health care system, vitamin D supplementation is focused on preventing rickets in children under 1 year old. There are three options:

1. Get more sun exposure. 7. Ultraviolet rays in the skin can convert cholesterol into vitamin D, which promotes calcium absorption and hardens bones. The specific situation should be determined by the season, and the baby's delicate skin should be protected. In the summer, you can choose to stay in the shade, and in the spring and autumn, you can often take your children to play outdoors. In winter, you can take more children outside to bask in the sun, preferably around noon.

2. Vitamin D should also be supplemented appropriately. Premature babies should start 2 weeks after birth, and full-term babies should start after one month. Within 3 months after birth, 800 international units can be used per day, and 400 international units can be used per day thereafter. Also add some calcium powder. At 2 or 3 years old, babies' growth rate slows down and their outdoor activities increase, so they generally do not need to take vitamin D.

3. The imperfect gastrointestinal system of infants will also affect absorption. It is recommended to add some intestinal flora at the same time as calcium, such as giving the baby colostrum. A sunny life is good, because children are immature, their bronchial, gastrointestinal and immune systems are relatively weak and prone to infection. Bovine colostrum is rich in immunoglobulins, which can neutralize and eliminate pathogenic intestinal bacteria, promote the growth of beneficial bacteria, and prevent intestinal diseases.
