Living in Northern Canada, I feel like I am constantly talking about Vitamin D. The importance of this super vitamin, however, is not limited simply to women who are living above the 60th parallel! From improving infant immune function (including decreased asthma risk) and decreasing risk of gestational diabetes and infant adiposity, to building optimal bone density in infants, the well-documented benefits lead me to recommend Vitamin D supplementation for all my pregnant patients.

During pregnancy, I routinely recommend the upper limit for Vitamin D – which has been identified as 4,000 IU per day. However, new research has highlighted the importance of increasing this dose to 6,000IU per day during lactation as a safe and effective was to elevate milk Vitamin D delivery to the mother’s baby.

Given the numerous benefits to both mom and babe of building adequate Vitamin D stores during pregnancy and lactation, and Vitamin D’s role as a preprohormone with impacts on post-partum depression and hormone balancing, this new dosing guideline is one I will be adopting!

I hope you have found this helpful, and do let me know if you have any questions!
