Vitamin D supplementation helps relieve symptoms of atopic dermatitis

[이데일리 이순용 기자]A study in Korea showed that vitamin D supplementation could reduce the risk of developing atopic dermatitis and relieve symptoms. This result supports the ‘vitamin D hypothesis’ that the prevalence of allergic diseases such as atopy and asthma is increasing as vitamin D deficiency is increasing worldwide.

According to the Korea Food Communication Forum (KOFRUM) on the 9th, Professor Dong-eun Seong of the Department of Food Science and Technology at Dongyang Mirae University analyzed 41 existing domestic and foreign research papers that tracked the relationship between vitamin D and atopy. The results of this study (functionality of vitamin D: a study on its effect on the control of atopic dermatitis) were introduced in the latest issue of the Journal of the Korean Society of Food Science and Technology.

Among the research papers reviewed by Prof. Sung, 70% showed improvement in the severity (symptoms) of atopic patients who took 1,000 to 5,000 IU (international unit) of vitamin D by mouth for 21 days to 3 months. In 57.1% of research papers (12 out of 21) that analyzed the correlation between blood vitamin D concentration and the prevalence of atopic dermatitis, it was concluded that the two were related. One of these research papers was that the incidence of atopy was 1.8 times higher in the group with blood vitamin D deficiency (less than 20 ng/ml) than in the sufficient group (more than 30 ng/ml).

Professor Sung pointed out in the paper, “Overall, vitamin D supplementation relieved the symptoms of atopic dermatitis.” He pointed out that “there is a possibility of using vitamin D to alleviate symptoms of allergic diseases, including atopy.”

Vitamin D is a type of fat-soluble vitamin that is necessary for the normal development of muscles and bones. Deficiency has only been known to cause rickets in infants and children and osteomalacia in adults. Recently, research results suggest that vitamin D is associated with several chronic diseases, including cardiovascular disease, infectious disease, diabetes, metabolic syndrome, cancer, and autoimmune diseases. It was found that the lower the level of vitamin D in the blood, the greater the likelihood of developing a COVID-19 infection, particularly the fatality rate.

Atopy can occur in both adults and children. It is a chronic, recurrent, inflammatory skin disease that is accompanied by severe itching and makes daily life difficult. Until now, the only treatment for atopic dermatitis is to apply a steroid ointment, but many patients are afraid of the side effects of long-term steroid use. This is spreading even to steroid phobia (phobia), and there is an urgent need for a natural substitute for atopy relief.
