Vitamin D in pregnancy may prevent allergies in babies

Dr. Rebecca Tocher-Richmond, ND

A recent study highlights the importance of Vitamin D during pregnancy.  This study has shown that Vitamin D status in early pregnancy has a significant effect on rates of allergies in young children.  Women with lower blood levels of vitamin D in early pregnancy were more likely to see atopy (allergic asthma and atopic dermatitis/eczema) in their children at 2 years of age.

We are seeing more allergies in young children than ever before, so it’s great to see a study showing such a potential approach to prevention.  Vitamin D supplements are affordable, readily available and easy to take.  Vitamin D is actually a hormone that our bodies can make in response to sun exposure.  Most people need to take vitamin D in supplement form because in Canada, we don’t get as much sun as we need to produce adequate amounts of vitamin D.  The skin’s ability to make vitamin D also decreases as we age.  Food sources of vitamin D are very limited making it nearly impossible to get sufficient vitamin D from diet alone.  A Naturopathic Doctor can give you advice about the correct dose and type of vitamin D for you.
