If you suffer from eczema, you know only too well how distressing this skin condition can be. Although there is no cure for eczema and each person has different symptoms, certain dietary supplements may help reduce the effects of inflammatory problems in the body on the skin or support the body's immune system. For example, omega-3 fatty acids from fish oil contain DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid), which may have powerful anti-inflammatory effects.
