[Used for] 2 Stars Depression 9.6 grams omega-3 fatty acids per day [Why] 
Depressed people have been reported to have low amounts of omega-3 fatty acids. Taking fish oil can replenish stores and stave off depression. Omega-3 fatty acids found in fish oil , particularly DHA , are needed for normal nervous system function. Depressed people have been reported to have lower omega-3 fatty acid levels (for example, DHA) than people who are not depressed.69 , 70 , 71 , 72 Low levels of the other omega-3 fatty acid from fish, EPA, have correlated with increased severity of depression.73 In some double-blind trials, supplementation with various amounts of fish oil was beneficial for the treatment of depression in both children and adults,74 , 75 but fish oil was ineffective in other double blind trials.76 , 77 EPA alone has also been reported to be beneficial. There is one case report of a man with a long history of severe depression who showed clear improvement within one month of starting a purified EPA supplement (4 grams per day of the ethyl ester of eicosapentaenoic acid [E-EPA]).78 In a double-blind study, supplementation with E-EPA for 12 weeks was significantly more effective than a placebo at relieving symptoms of depression.79 E-EPA was beneficial, even though the participants in the study had failed to respond adequately to conventional antidepressant drugs. The conventional medications were continued during treatment with E-EPA or placebo. An effective level of intake was 1 gram per day, whereas larger amounts of E-EPA resulted in little or no benefit. The authors of the study suggested that taking too much E-EPA might cause an imbalance with other essential fatty acids, which could reduce the effectiveness of the treatment.
