How does low vitamin D worsen eczema?

Eczema is a skin condition that is most commonly found among infants. However, many people will continue to have this condition into their adult life. Eczema can be caused by exposure to various environmental factors or it can simply be genetic. Eczema is a general term for any sort of dermatitis or itchy rash. This rash can flare up all over the body. However, the most common areas of eczema are the inside of the elbows, back of the knees, and all over the face and neck. Depending on exposure to irritants, allergies, foods, and stress levels the severity of eczema varies. 

Eczema is shown to be linked to allergic diseases such as asthma and thus, may increase with increased allergies. In more recent studies, people with eczema have shown to have very low levels of vitamin D. Vitamin D is a crucial vitamin that aids in boosting your immune system. It reduces levels of inflammatory proteins and increases the production of good antimicrobial proteins. Therefore, if one is experiencing severe eczema, their immune system is not functioning properly. Recent studies have shown that because of the lack of vitamin D present in the body, the immune system is not able to fight off any bacteria or virus that might cause irritation to the skin.  Lower vitamin D levels have been linked to more severe cases of eczema. Having a sufficient amount of vitamin D in your body, helps decrease inflammation and increase the strength of the skin’s barrier preventing the cause of eczema.

A study published in 2013 in Poland gave vitamin D supplements to adults with eczema who had low levels of vitamin D. The people all got 2000 IU of vitamin D daily for 3 months in the wintertime. The researchers looked at eczema severity and symptoms before and after supplementation and found that:

  • People with the lowest vitamin D levels had more skin infections.
  • After supplementing with vitamin D, the eczema symptoms and severity score was much lower.
  • People who took vitamin D supplements had significant improvements in skin lesions.

The researchers conclude that supplementing with vitamin D may help to manage and treat the skin symptoms associated with eczema. Vitamin D causes skin cells to make more antimicrobial proteins, which is why people with low levels of vitamin D tend to have more skin infections.
