Clinical Trial Summary

Background: Patients with major depressive disorder have prominently been reported to be related with subnormal polyunsaturated omega-3 fatty acids levels, importantly low docosahexaenoic acid and eicosapentaenoic acid in plasma and dietary intake. However, more randomized controlled trials are needed to support its importance in management of depression.
