Enhanced Levels of Vitamin D May Alleviate Eczema Symptomatology
Eczema, a common skin condition affecting around 20 percent of children and 5 percent of adults, has been linked to vitamin D deficiency. Researchers have noticed a connection between lower vitamin D levels and higher rates of eczema, particularly in areas with less sunlight.
Vitamin D, often referred to as the 'sunshine vitamin', is essential for maintaining a healthy immune system and supporting the skin barrier. It does this by helping to regulate specific proteins that strengthen the skin barrier, which is abnormal in people with eczema.
Foods rich in vitamin D include fatty fish such as salmon, mackerel, and herring, as well as cod liver oil, eggs, fortified drinks like milk and juice, liver, and sardines. However, due to factors such as darker skin having more melanin, a pigment that can interfere with vitamin D production, and the limited sunshine during certain seasons, many people may find themselves deficient.
Sunshine is the primary way to increase vitamin D levels, but supplements are necessary for many people, at least for part of the year. A meta-analysis concluded that vitamin D dosages ranging from 1000 to 1600 IU a day were effective in improving eczema symptoms.
Vitamin D supplements are not the only dietary changes that can help manage eczema. Adding more zinc to your diet may be helpful for those at an increased risk of eczema due to a zinc deficiency. Vitamin E, when taken with vitamin D, has been found to help reduce eczema symptoms. Probiotics can also help turn down immune reactions that could flare up eczema symptoms.
Fish oil, which fights back against inflammation, could also help eczema. Studies on adults found that taking vitamin D for 2 months lessened the severity of eczema. Similarly, studies on nursing mothers have found that increased sunlight exposure and vitamin D supplementation can increase the vitamin D status of their babies.
However, it's important to note that excessive sun exposure can lead to skin damage. Wearing protective sun clothing and sunscreen can block UV rays and prevent vitamin D production.
In conclusion, maintaining adequate vitamin D levels through a balanced diet and supplements, if necessary, could help manage eczema symptoms. It's always best to consult with a healthcare professional to determine the best approach for individual cases.
