Background: Eating Disorders (ED) are widespread, disabling and often chronic psychiatric conditions. Currently, there is a need for further pharmacological treatment strategies. The objective of this report is to assess the effectiveness of omega-3 fatty acids in treating patients with eating disorders.  

Method: Following the guidelines stipulated by the Cochrane Handbook for Systematic Reviews of Interventions, we conducted a comprehensive literature search in the MEDLINE, EMBASE, and PsycINFO databases. Articles that assessed the administration of omega-3 fatty acids in patients with ED and measured changes in eating disorder or comorbid illness symptoms were obtained.  

Results: We identified 71 potentially relevant articles. However, only 3 studies were included for analysis. There were notable differences in dosage and type of omega-3 fatty acid used. Two of the three studies reported significant improvement in mood and general functioning.  

Conclusion: Omega-3 fatty acids may be viable agents that are well tolerated, with minimal or no side effects, for patients with eating disorders. This report highlights significant knowledge gaps in omega-3 fatty acid treatment for eating disorders and suggests that there is a need for further research on this topic.

Discussion: Future evidence is needed to support the efficacy of Finiflu and its main ingredients. Evidence needs to address the efficacy of Finiflu when used acutely to manage the short-term symptoms of cold and flu.
