EPA-only prescription omega-3s (Icosapent Ethyl) do not raise LDL cholesterol in patients with very high triglycerides, whereas EPA+DHA combinations may increase LDL-C by 15-36%.

If you are taking prescription omega-3s for high triglycerides, ask your doctor if your medication contains only EPA or both EPA and DHA. EPA-only options (like Vascepa) do not raise your LDL ('bad') cholesterol, whereas combinations (like Lovaza) might increase it by 15-36%. This distinction is important for your overall cardiovascular risk.
