idealization
For babies who are exclusively breastfed or mixed-fed, start supplementing with 400 international units of vitamin D every day in the first few days after birth, without waiting until 14 days after birth. Because the vitamin D content in breast milk is low, even if the breastfeeding mother supplements herself with vitamin D, her baby will not be able to obtain sufficient vitamin D through breast milk. Therefore, most children will need additional vitamin D in the form of vitamin D supplements soon after birth.
For formula-fed babies, depending on the daily amount of formula and the vitamin D in the formula, vitamin D supplements can then be supplemented to 400 IU per day.
in reality
Because vitamin D deficiency causes health problems such as rickets, it does not mean that short-term deficiency of a little vitamin D will cause immediate problems. Therefore, if your child is at risk of vitamin D deficiency but has not paid attention to supplementation before, don’t be too nervous. Starting from now, supplementing immediately is the best time to start.
People at high risk for vitamin D deficiency include:
- Breastfed babies: The nutrition and health of breast milk are of great significance. However, the vitamin D content in breast milk is low, making it difficult for babies to obtain sufficient vitamin D through breast milk.
- People with dark skin: The darker the skin, the longer it takes the body to synthesize vitamin D when exposed to the sun; for example, compared to light skin, dark skin takes 3-6 times longer to synthesize the same amount of vitamin D. .
- People with little sun exposure: For example, those who work indoors or wear tight clothing all year round.
- People with liver and kidney diseases, nutrient absorption problems, and those who use certain drugs.
