Hey, baby, how much vitamin D is enough?Hope WeilerIUthe School of Dietetics and Human Nutrition
Vitamin D is especially important for babies in the first 12 months of life when bones are growing rapidly, but new research shows more is not necessarily better. As early as the three-month mark, it was clear that there was no advantage to the higher doses of vitamin D and that 400 IU per day was sufficient.
“There’s sometimes a feeling that more is better,” says Hope Weiler, professor in the School of Dietetics and Human Nutrition at McGill University. “But until now, no one had compared the popularly recommended daily doses of vitamin D to see what will result in optimal health for infants.”
Current recommendations about how much vitamin D a baby needs daily in order to build healthy bones and prevent rickets vary widely. In France and Finland, the recommended daily dose is of 1,000 IU for infants. At the lower end of the scale, Health Canada and the World Health Organization both recommend a daily dose of 400 IU.
