Vitamin D reduces skin eczema

Recent studies suggest vitamin D plays a role in the skin condition atopic dermatitis (AD), or eczema. Doctors reviewed the research database for all AD studies through May, 2015, and found that, overall, those with AD are more likely to have low levels of vitamin D, and that supplements can help. On average for all age groups, those with AD had vitamin D levels that were 2.03 nanograms per milliliter of blood (ng/mL) lower than those without AD. Children with AD had even lower vitamin D levels: 3.03 ng/mL lower than healthy kids.

The studies also suggested that adding vitamin D supplements reduced AD symptoms in all groups. Doctors don’t know what causes eczema, but many people with the condition also have a family history of allergy or asthma.
