[Used for] 2 Stars Psoriasis Take orally 10 grams daily oil or 3.6 grams daily EPA, or apply a 10% topical solution twice per day [Why] 
Fish oil has been found to reduce the severity of psoriasis and improve skin lesions. It also may help prevent increased triglyceride levels that result from certain psoriasis drugs. In a double-blind trial, fish oil (10 grams per day) was found to improve the skin lesions of psoriasis.122 In another trial, supplementing with 3.6 grams per day of purified eicosapentaenoic acid (EPA, one of the fatty acids found in fish oil) reduced the severity of psoriasis after two to three months.123 , 124 That amount of EPA is usually contained in 20 grams of fish oil, a level that generally requires 20 pills to achieve. However, when purified EPA was used in combination with purified docosahexaenoic acid ( DHA , another fatty acid contained in fish oil), no improvement was observed.125 Additional research is needed to determine whether fish oil itself or some of its components are more effective for people with psoriasis. One trial showed that applying a preparation containing 10% fish oil directly to psoriatic lesions twice daily resulted in improvement after seven weeks.126 In addition, promising results were reported from a double-blind trial in which people with chronic plaque-type psoriasis received 4.2 g of EPA and 4.2 g of DHA or placebo intravenously each day for two weeks. Thirty-seven percent of those receiving the essential fatty acid infusions experienced greater than 50% reduction in the severity of their symptoms.127 Supplementing with fish oil also may help prevent the increase in blood levels of triglycerides that occurs as a side effect of certain drugs used to treat psoriasis (e.g., etretinate and acitretin).128
