Omega-3 EPA/DHA Fish Oil, graded Moderate-evidence on Magellan — doses above 1 g/day carry a genuine atrial-fibrillation signal - about 13% higher incident risk in a large cohort of healthy users. Standard over-the-counter doses did not prevent cardiovascular events or cancer in large trials (VITAL, STRENGTH) and meta-analyses, though triglyceride lowering is real.

Omega-3 fatty acids are long-chain polyunsaturated fats, principally eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found mainly in oily fish and fish oil; a plant-derived form, alpha-linolenic acid (ALA), occurs in walnuts and flaxseed. Because the body cannot synthesize them, they must be obtained from diet or supplements. EPA and DHA are incorporated into cell membranes and act as substrates for specialized pro-resolving lipid mediators (resolvins, protectins and maresins) that help resolve inflammation. Their most consistent metabolic effect is a dose-dependent lowering of blood triglycerides.
Across large randomized trials and meta-analyses, marine omega-3s reliably reduce serum triglycerides (roughly 15% at higher doses) and modestly lower blood pressure and resting heart rate, but their effect on cardiovascular events is mixed and depends on dose, formulation and population. High-dose purified EPA (icosapent ethyl) reduced ischemic events by 25% in the REDUCE-IT trial in statin-treated patients with elevated triglycerides, whereas 1 g/day of EPA+DHA showed little overall benefit in the VITAL primary-prevention trial, high-dose EPA+DHA carboxylic acids were no better than corn oil in the STRENGTH trial, and Cochrane concluded supplements have little or no effect on all-cause or cardiovascular mortality. High doses (above 1 g/day) also raise the risk of atrial fibrillation - in a large UK Biobank cohort, regular fish-oil use was associated with a 13% higher risk of incident atrial fibrillation in people without cardiovascular disease, though possibly with benefit once disease is established - so benefits and harms must be weighed. This evidence describes the EPA/DHA compounds and their mechanisms in human health, not this specific commercial product.
