The lack or excess of vitamin D is detrimental to health, so many doctors have recommended that parents should supplement vitamin D with a dose depending on the age of the child. So how to supplement vitamin D?

1. Why do children need vitamin D3 supplements?

Vitamin D is a fat-soluble vitamin that exists in two forms: Vitamin D3 cholecalciferol) and Vitamin D2 (ergocalciferol). Accordingly, Vitamin D3 is better than other types of Vitamin D and increases blood levels of vitamin D nearly twice as high as Vitamin D2.
From a nutritional perspective both forms are metabolized similarly. At birth, infants have a limited amount of vitamin D3 stores, mainly being passed from mother to fetus during pregnancy. After birth, infants can get vitamin D3 through breast milk (0.5-1.8 micrograms/liter) and through supplements. Vitamin D3 can also be made in the skin of infants when exposed to the UV rays of sunlight. However, at latitudes greater than 37 degrees north or south, UV rays are too low to produce enough vitamin D3 in late fall to early spring. In addition, the skin's melanin pigment absorbs UV rays and thus it limits the ability to make vitamin D3 for people with dark skin. Parents should limit their newborn's exposure to solar radiation by using hats, blankets, and avoiding direct sunlight. Therefore, the main sources of vitamin D3 for infants include vitamin D3 from mother to baby during pregnancy and after birth from diet and supplements.

Infant vitamin D3 deficiency is widespread worldwide, including in many different geographic regions and cultures. This is partly because not all health care professionals recommend vitamin D3 supplements even after you've exclusively breastfed your baby. Furthermore, some parents are not aware of the importance of vitamin D3 and parents think that their children do not like the supplement.

2. How to supplement vitamin d3 for children?


In 2008, the American Academy of Pediatrics recommended the general use of vitamin D and there is no specific recommendation for vitamin D3, so parents can refer to this recommendation as follows:
All infants, Children and adolescents get a minimum of 400 IU of vitamin D per day through diet or supplements. Parents need vitamin D supplements for babies, however, if an infant is formula-fed with adequate amounts of vitamin D through milk, additional supplementation may not be needed. Exclusively or partially breastfed infants, as well as children and adolescents who consume less than 1 liter of vitamin D fortified milk per day, should receive an additional 400 IU of vitamin D per day.

Vitamin D3 (cholecalciferol) is the preferred form of vitamin D for supplementation. Children with certain medical conditions, such as fat malabsorption and those requiring long-term medication, may need higher doses of vitamin D because of an increased risk of deficiency. There is no evidence to suggest that supplementing with 400 IU of vitamin D daily is toxic. However, parents need to use it for children according to the instructions of the doctor.
