Psoriasis is medical disorder characterized by overgrowth or the skin cells and inflammation of the skin. Although the exact cause is unknown, certain factors like injuries, sunburn, infections, alcohol and stress are known to trigger this condition, according to the Merck Manual. Based on research studies, essential fatty acids, and particularly EPA appear to be beneficial for improving symptoms of psoriasis. If you consider taking this supplement for your condition, talk to your doctor first.
About Essential Fatty Acids
Essential fatty acids are nutrients that are important for optimal health. Because they are not produced in the body, essential fatty acids have to be obtained from foods and supplements. There are two main types: omega-3 and omega-6 fatty acids. EPA, or eicosapentaenoic acid, and DHA, or docosahexaenoic acid, are forms of omega-3 essential fatty acids, and their key role is to reduce inflammation. On the other hand, most omega-6 fatty acids promote inflammation, although a few of them, like GLA gamma-linolenic acid, have anti-inflammatory effects and are considered healthy. Dietary sources of omega-3 include fish, whole grains, some fruits and vegetables, olive oil and garlic. Fish oil supplement is also a source of the omega-3 fatty acids EPA and DHA. Dietary sources of healthy omega-6 GLA include vegetable oil like primrose, borage and black currant seed oils. The unhealthy omega-6 fatty acids that promote inflammation are found in red meat and animal fat.
Omega-3 Research
Based on the anti-inflammatory effects of omega-3, several research studies evaluated the benefits of this supplement for treating psoriasis. Omega-3, particularly EPA in oral, injectable and topical forms, showed positive effects, according to a study published in July 2007 issue of "European Journal of Dermatology." The authors also found that topical application of EPA helps reduce inflammation and improve symptoms of psoriasis when used either alone or in combination with standard medication. Another study, published in the January 2009 issue of "Anais Brasileiros de Dermatologia," also said that high intake of omega-3 essential fatty acids, along with fasting and vegetarian diet, are beneficial for psoriasis sufferers.
Omega-6 Research
Omega-6 from evening primrose oil used with fish oil showed positive results in a preliminary study conducted by a German research team. This study, published in the 1989 issue of " Acta Dermato-Venereologica," found that the supplement improved symptoms of psoriasis in the majority of the subjects who participated in the study.
Considerations
Consult a qualified health-care provider to find out an optimal dosage of essential fatty acids that may help your condition. Essential fatty acids do not replace and should not be used to replace standard medication prescribed for psoriasis. They are not approved by U.S. Food and Drug Administration to treat this condition.
