Studies
These studies provide scientific insights into Omega-3 benefits:
A 1999 GISSI-Prevenzione trial in 11,324 post-MI patients showed 1 g/day EPA + DHA for 3.5 years reduced all-cause mortality by 20 % versus control .
A 2004 double-blind RCT in 65 hypertriglyceridemic subjects found 4 g/day fish oil for 8 weeks lowered triglycerides by 25 % versus 5 % with placebo, with modest HDL-C increase.
Despite cardiovascular benefits, no RCTs have directly compared fish oil to prescription omega-3 formulations for arrhythmia prevention in healthy adults.
