Omega-3 Fatty Acids (EPA/DHA) for High Triglycerides (Hypertriglyceridemia)

A

Multiple meta-analyses confirm omega-3 at 2-4g/day reduces triglycerides by 15-30%. FDA-approved prescription omega-3 (Vascepa, Lovaza) for severe hypertriglyceridemia. REDUCE-IT showed 4g/day EPA reduced cardiovascular events by 25%. AHA guideline-endorsed.
