Antioxidant intake during pregnancy may reduce the risk of eczema in offspring

Allergies such as atopic eczema, rhinitis and asthma are increasing in incidence in children. This prospective cohort study performed in 5 yr old Finnish children (n= 2441) showed that magnesium intake in pregnancy was linked to a lower incidence of atopic eczema in the offspring (OR: 0.78, CI: 0.62-0.97). There were similar effects for vitamin C and riboflavin initially, but proved to be insignificant once the odds ratio was adjusted for confounders. Thus maternal intake of magnesium may protect against the risk of eczema, but not allergic rhinitis or asthma. Because an allergic response results in an increase of oxygen-free radicals, there may be a critical time period in pregnancy where antioxidants may decrease the risk of allergies.

Magnesium can be found in PM Procare (Pregnancy & Breastfeeding formula and AB Extra Bone-care+ (comprehensive calcium supplement for prevention of osteoporosis.).
