Can you take Omega-3 Fatty Acids (EPA/DHA) with Statins (HMG-CoA reductase inhibitors)?

What the evidence says
Statins are the mainstay for lowering LDL cholesterol, but they only modestly lower triglycerides, and omega-3 (EPA/DHA) has been studied specifically as an add-on to statin therapy rather than a replacement for it. In the JELIS trial, more than 18,000 people with high cholesterol were randomised to a statin alone or a statin plus 1.8 g of EPA daily — a dose achievable with over-the-counter fish oil — and the EPA group had 19% fewer major coronary events over roughly five years (the trial was open-label and run in a Japanese population that already eats a lot of fish, so the size of the benefit may not carry over directly elsewhere). A systematic review and meta- analysis of combination trials found statin-plus-omega-3 improved the overall lipid profile more than a statin alone — mainly triglycerides and cholesterol ratios — though it did not lower LDL any further and caused more gastrointestinal side effects. This is a supportive pairing, not a risk, but omega-3 doses above about 1 g/day carry their own trade-offs (including a dose-dependent atrial fibrillation signal in cardiovascular outcome trials), so if your triglycerides stay high on a statin, discuss adding omega-3 — and the right dose — with your prescriber rather than self-selecting a high dose.
