Abstract
A comprehensive scientific advisory from the American Heart Association examining omega-3 fatty acids and cardiovascular health, including mechanisms of action and clinical trial evidence.
Methodology
American Heart Association science advisory reviewing 17 randomised controlled trials of prescription-strength omega-3 fatty acids for hypertriglyceridaemia, covering EPA-only and EPA/DHA formulations, dosing and safety.
Key Findings
Prescription omega-3 at 4 g daily lowered triglycerides by roughly 20-30% in patients with hypertriglyceridaemia, effective as monotherapy or added to statins. EPA-only and EPA/DHA products lowered triglycerides comparably, though EPA/DHA products modestly raised LDL cholesterol in some patients. Over-the-counter supplements are not equivalent because of lower and variable EPA/DHA content.
Conclusions
Prescription omega-3 at 4 g daily is an effective and safe treatment for hypertriglyceridaemia; supplement-strength fish oil should not be substituted for it.
Limitations
Advisory rather than systematic review with formal bias grading; underlying trials differ in formulation, baseline triglycerides and background therapy; several authors report ties to omega-3 manufacturers.
Supplements Studied
Prescription omega-3 at 4 g daily lowered triglycerides by roughly 20-30% in patients with hypertriglyceridaemia, effective as monotherapy or added to statins. EPA-only and EPA/DHA products lowered triglycerides comparably, though EPA/DHA products modestly raised LDL cholesterol in some patients. Over-the-counter supplements are not equivalent because of lower and variable EPA/DHA content.
Outcomes Measured
Omega-3 fatty acid supplementation produces modest reductions in blood pressure and other cardiovascular risk factors.
