Background: As regard to high prevalence of Helicobacter pylori infection and complications of it's persistence, as well as anti-bacterial activity against of Helicobacter pylori and anti-inflammatory properties of omega-3 fatty acids, this study was conducted to evaluate the effects of supplementation with Docosahexaenoic Acid (DHA) on the eradication of Helicobacter pylori infection, some serum inflammatory markers and total antioxidant capacity. 
Methods: In a double-blind, placebo-controlled clinical trial, 66 H. pylori positive patients (33 in the intervention group and 33 in the control group), along with tetra-drugs H. pylori eradication regimen, randomly received daily two grams morDHA supplement or Medium Chain Triglyceride (MCT) oil as placebo for 12 weeks. Dietary intake data was collected by 24 hour food recall and analyzed by Nutritionist IV software. Sampling from fasting blood and measuring weight, height, body mass index (BMI) and level of physical activity were done at the first and the end of the study. As well as, eradication test of the infection was performed for all patients at the end of the intervention. 
Results: Eradication rate of the infection, the level of interleukin-6 (IL-6), high sensitivity C-reactive protein (hs-CRP) and total antioxidant capacity (TAC) didn't have significant difference between two groups at the end of the study (P>0.05), while the level of interleukin-8 (IL-8) was different between two groups (P=0.008). Difference of the concentration between the beginning and the end of the study was not significant in any factors between two groups (P>0.05).  
Conclusion: Intake of morDHA supplement didn't have significant effect on the eradication of H. pylori, serum levels of IL-6, hs-CRP and TAC, while it was effective on the level of IL-8.
