Vitamin D is a fat-soluble vitamin, so she recommends taking it with a meal, not on an empty stomach, as the fat in food can promote its absorption.

For infants and young children under 2 years old, due to their rapid growth and development, they are prone to relative vitamin D deficiency, especially breastfed infants, high-risk infants, and frail infants, and it is recommended to take vitamin D or high-quality cod liver oil prophylactically.

Extended information: Vitamin D is mainly synthesized by ultraviolet radiation, and is mainly used in marine fish liver, and very rarely, in milk, egg yolk, etc. The main physiological role of vitamin D is to regulate calcium and phosphorus metabolism to promote bone development, as well as to regulate immune function.

Lack of vitamin D can easily lead to rickets (a common disease in infants and young children), causing bone changes, and in severe cases, square skull, pectus excavatum, rickets, X-shaped legs or O-shaped legs, etc.

If a large dose of vitamin D is given several times in a short period of time, or if the prophylactic daily intake of vitamin D is too large, and multiple intramuscular doses of vitamin D, it may lead to hypercalcemia caused by vitamin D overdose, and then lead to impairment of the function of multiple organs.

Vitamin D poisoning is mainly manifested by decreased appetite or anorexia, recurrent infections, polyuria, kidney stones, etc. However, prophylactic use of less than 800 IU per day generally does not cause accumulation poisoning. A daily intake of 2000IU is the lowest dose that occurs, which can cause hypervitamin D and generally requires continuous supplementation to cause poisoning, and needs to be taken continuously for more than a month.

The benefits are limited.

Normal full-term newborns should be added vitamin D from two weeks after birth, and premature babies or twins should be added from one week after birth, with a minimum prevention amount of 400 units per day to promote the absorption of calcium in the body and prevent the occurrence of rickets, and it is recommended to eat until the age of two.

If it is a child in the north, the weather is cold in winter, outdoor activities are significantly reduced, or if there are no outdoor activities, it is very easy to lack vitamin D, so in winter, you can appropriately increase the amount of oral vitamin D, at least 800 units per day.

Normally born children need to supplement vitamin D3400IU D, which is generally taken from half a month to 1 month after birth and until 2-3 years old.

Preterm infants should be given vitamin D 3800 to 1000 IU daily after birth and 400 IU daily after 3 months of corrected age until 2 to 3 years of age.

In addition to vitamin D3 preparations, formula milk also contains a certain amount of vitamin D3. Formula-fed babies need to supplement the deficiency according to the amount of vitamin D3 contained in the formula.

400IU is a daily prophylactic amount, not a ** amount. If the baby has rickets, the dose must be increased under the guidance of the doctor and the corresponding ** must be given.

Supplementing with vitamin D3 is low at 10,000 IU d, which usually does not cause toxicity, but too high a vitamin D3 intake will increase the risk of ***.

1. Infants should be supplemented with 400-800 units of vitamin D3 every day, and take calcium tablets appropriately and get in the sun.

2. Vitamin D3 is a kind of natural vitamin D, which is a fat-soluble vitamin, which has an important function, which is to improve the body's absorption of calcium and phosphorus. Therefore, vitamin D3 supplementation is more important than calcium supplementation itself. Only an adequate amount of vitamin D3 can ensure the healthy growth of children.

Many babies have symptoms of calcium deficiency, in fact, to be precise, the baby is deficient in vitamin D. Breast milk generally contains vitamins that meet the needs of infants, unless they are fed non-infant formula, vitamin D should be supplemented from 2 weeks of life to 1 1/2 years of age. So, how much vitamin D3 does your baby eat a day?

One microgram (g) is equal to 40 international units (IU), and microgram of vitamin D3 is equal to 180 IU. Vitamin D plays a very important role in the development of human bones, and the growth and development of bones is vigorous in infancy and early childhood, so sufficient vitamin D is needed to maintain normal bone development. However, the more vitamin D supplementation the baby is, the better, and the intake of vitamin D for infants must be grasped to a certain degree.

Normal children, regardless of age, require 400 units of vitamin D/day per person, while premature infants, congenital inadequate stores, or hyperthrogenic infants need increased requirements. Therefore, the amount of oral vitamin D should be increased appropriately. There are many preparations of vitamin D, and parents can choose their own and give their children a ration every day.

Generally, it is taken from half a month to one month after birth and continues until the age of 2 and a half or 3 years.

It should be noted that vitamin D3 should be supplemented in moderation, if you are not sure how much is appropriate, you should consult a professional doctor to avoid poisoning when the baby overdoses.
