Vitamin D supplementation in pregnancy can lower risk of childhood allergies

Babies born to mums with sufficient pregnancy vitamin D levels are less likely to have eczema and asthma in early childhood, recent research suggests. The Taiwanese study, which assessed 164 mother-child pairs from the infant's birth to four years of age, found that higher maternal vitamin D levels (> 30 ng/mL) were significantly associated with a lower risk of eczema (p = 0.012) and asthma (p = 0.038) in their four year old offspring.
