Roll Call does not check drug interactions or assess personal safety.
A long-chain omega-3 fatty acid found in fatty fish and algae, and made in small amounts by the body from other omega-3 fats.
Why it’s used
Taken to support cardiovascular health, brain and eye function, and is often paired with EPA in fish oil supplements.
What the evidence is for
lowering triglyceride levels at higher combined EPA+DHA doses.
What the evidence says
NIH ODS notes that combined EPA and DHA intake, especially at higher doses, lowers triglyceride levels. DHA's role in fetal and infant brain and eye development is also well documented. Evidence for broader cardiovascular event reduction or cognitive benefit in general adult populations is less consistent.
Dose studied
2–4 g — combined EPA+DHA doses studied for triglyceride lowering, per NIH ODS.
Context
Triglyceride-lowering studies have generally used combined EPA+DHA doses of about 2-4 g/day; DHA-specific research on pregnancy and infant development has used lower doses.
