Associations of habitual fish oil supplementation with cardiovascular outcomes and all cause mortality: evidence from a large population based cohort study

Study (n=427,678 from UK Biobank.) found habitual use of fish oil seems to be linked to lower risk of all cause (HR 0.87; 95% CI, 0.83-0.90) and CVD mortality (0.84; 0.78-0.91) and a marginal benefit against CVD events (0.93; 0.90-0.96) among the general population.
