Vitamin D3 supplementation begins about two weeks after birth and is more effective when taken after breastfeeding.
Vitamin D3 can promote calcium absorption, can effectively prevent vitamin D3 deficiency rickets. The fetus can obtain vitamin D3 from the mother through the placenta, and the storage of vitamin D3 in the fetus can meet the growth needs for a period of time after birth.
However, because of the small amount of vitamin D3 in breast milk, it cannot meet the infant’s needs, so infants can start supplementing vitamin D3 two weeks after birth.
Since vitamin D3 is a fat-soluble vitamin, vitamin D3 is usually given to babies after breastfeeding to promote the absorption of vitamin D3. While taking vitamin D3 should also pay attention to appropriate more sun exposure, more sun exposure is an easy and effective measure to prevent vitamin D3 deficiency.
It is recommended that the baby vitamin D3 supplementation to about two years of age, if the baby has vitamin D3 deficiency rickets, can be appropriate to extend the supplementation time.
