Vitamin D: The New Eczema Cure

0

Daily supplements of vitamin D might help kids with eczema, according to a study from Harvard Medical School in Boston. Vitamin D supplements (1,000IU/day) or placebos were given to 107 children (average age was 9-years-old) with atopic dermatitis that flared up in cold weather or during the transition from Fall to Winter. Symptoms were evaluated at the study’s start and one month later. Results showed that those children who supplemented with vitamin D had a significant 29% improvement in symptoms compared to placebos. There were no adverse effects from the supplements.
In Perspective: A common treatment for eczema is the use of ultraviolet light that stimulates production of vitamin D in the skin. This study suggests that lack of the “sunshine vitamin” might explain why the skin condition worsens in the Fall and Winter.
