Trio of Studies Explore Asthma and Vitamin Connection

Several studies provide additional information regarding the connection between asthma and vitamins D and E. Each is summarized below:

  • A study in the April, 2015, edition of Clinical & Experimental Allergy found an association between low maternal levels of vitamin D and E and infant airway reactivity to environmental factors such as dust. Click here to read more.
  • A study in the April, 2015, edition of the European Respiratory Journal examined the vitamin E and D level of pregnant women and tracked the development of asthma in their children. The authors found that “low maternal vitamin D and E intakes during pregnancy are associated with increased risk of children developing asthma in the first 10 years of life. Click here to read more.

As noted in this article summarizing both studies, caution is warranted when interpreting the results. “[T]he women’s diets are surely closely linked to their lifestyles and there are several confounding factors not taken into account. In the future, a clinical study of mothers taking vitamin D and E supplements vs. placebo no treatment) is warranted to give a more definitive answer to this question.”

  • A study in the August, 2015, edition of the British Journal of Nutrition found that “in children previously diagnosed with asthma, vitamin D supplementation resulted in a 74 % reduction in the risk of asthma exacerbation,” suggesting that vitamin D “supplementation may benefit children previously diagnosed with asthma. Due to the heterogeneity of the included studies and possible publication biases related to this field, these results should be interpreted with caution.” Click here to read more.
