Deficiencies in certain nutrients including vitamins and minerals are known to influence the severity of eczema symptoms. Imbalances in omega-6 to omega-3 polyunsaturated fatty acid intake in particularly may play a role in inflammation.
Vitamin D also reduces skin inflammation, and may directly regulate circulating IgE levels. Patients with eczema have also been shown to have low blood serum vitamin D levels; less exposure to sunlight, which we need for our bodies to manufacture vitamin D, is correlated with symptom flare-ups.
Blood cell zinc deficiency is also associated with eczema severity.
If you are concerned about eczema, or any other irregularities or abnormalities in your skin, it is recommended you consult your GP, and take supplements only under guidance from a registered nutritional therapist or nutrition practitioner.
