Vitamin D3 – Starting Supplementation in Childhood

For those of us living relatively far North of the equator, vitamin D deficiency is a common finding, and the health consequences are a popular topic in adult healthcare. Adequate levels of the active form of the vitamin (Cholecalciferol) are necessary for proper immune function, maintaining cardiovascular health, preventing osteoporosis, cancer prevention, healthy pregnancies and more.

When considering vitamin D supplements as a therapy, one group that may be commonly overlooked is children. Although children receive vitamin D supplementation through fortified milk, fortified non-dairy beverages, and healthy food choices, new research funded by the Canadian Institutes of Health Research and St. Michael’s Foundation conveys that current diets may not provide enough.

Dietary records of Canadian infants suggest they are consuming only 11% of their recommended daily allowance of vitamin D at one year of age. Vitamin D deficiency in children can disrupt proper growth and development, and predispose them to asthma, allergies and more. Doctor Jonathan Maguire’s most recent study looked at serum levels of the vitamin in 1,898 children, and compared it to their variable intakes of vitamin D supplements and fortified milk. The researchers discovered that children under 6 years of age were most likely to maintain higher blood levels if they were given both a vitamin D supplement and 2 glasses of cow’s milk daily.

Many children do not receive daily vitamin D supplements, and for some, cow’s milk is an allergen that must be avoided. For these children, vitamin D supplementation is especially important.

Here in the NW, where sun is rare and families often avoid intake of dairy for reasons of allergy or conscience, I recommend considering vitamin D supplementation for your little ones. Below are some suggestions and general information.

 Safe Vitamin D3 (Cholecalciferol) Dosing for Children:

~For infants, children & adolescents, 400 IU daily is a safe dosage

~400 IU is safe in addition to breastfeeding, infant formula, or cow’s milk

~Do not exceed 1,000 IU daily in infants under 12 months of age

~Consider 600-1,000 IU daily for children >12 months old who do not drink cow’s milk
