Vitamin D Might Help Kids With Eczema. FRIDAY, Oct. 17, 2014 (HealthDay News) -- Daily vitamin D supplements might help children with eczema that gets worse in the winter, a new study suggests. When eczema, a chronic inflammatory skin disorder, flares up in the winter it's known as winter-related atopic dermatitis.
Vitamin D is the name given to a group of fat-soluble prohormones (substances that usually have little hormonal activity by themselves but that the body can turn into hormones). Vitamin D helps the body use calcium and phosphorus to make strong bones and teeth. Skin exposed to sunshine can make vitamin D, and vitamin D can also be obtained from certain foods. Vitamin D deficiency can cause a weakening of the bones that is called rickets in children and osteomalacia in adults. Two major forms of vitamin D that are important to humans are vitamin D2, or ergocalciferol, and vitamin D3, or cholecalciferol.
