About The Study: The results of this study suggest that the majority of fish oil supplement labels make health claims, usually in the form of structure/function claims, that imply a health benefit across a variety of organ systems despite a lack of trial data showing efficacy. Significant heterogeneity exists in the daily dose of eicosapentaenoic acid + docosahexaenoic acid in available supplements, leading to potential variability in safety and efficacy between supplements.
