Vitamin D Helps Prevent Skin Infections

A study led by researchers at the University of California, San Diego School of Medicine suggests that use of oral Vitamin D supplements bolsters production of a protective chemical normally found in the skin, and may help prevent skin infections that are a common result of atopic dermatitis, the most common form of eczema.

Study participants were all given 4000 IUs of oral Vitamin D3 (cholecalciferol) per day for 21 days. Skin lesions were biopsied before and after the 21-day period. The researchers found that oral vitamin D use by the patients appeared to correct the skin’s defect in cathelicidin. “These results suggest that supplementation with oral vitamin D dramatically induces cathelicidin production in the skin of patients with atopic dermatitis,” said Hata. “It also slightly elevated its production in normal skin in this study.”

Significantly more patients with Parkinson’s disease (55 percent) had insufficient vitamin D than did controls (36 percent) or patients with Alzheimer’s disease (41 percent),” the authors wrote.
