An oil extracted from cultivated marine algae, naturally rich in the omega-3 fatty acid DHA and sometimes EPA. It serves as a plant-based (technically algae-based) alternative to fish oil.

Why it’s used

Taken as a source of omega-3 fatty acids, particularly by people avoiding fish-derived products, to support cardiovascular and general omega-3 intake.

What the evidence is for

raising blood omega-3 (DHA) levels and lowering triglycerides at higher doses.

What the evidence says

NIH ODS notes that omega-3 fatty acids, including DHA from algal sources, reliably raise blood omega-3 levels and have evidence supporting a role in triglyceride reduction at higher doses; evidence for broader cardiovascular event prevention from supplemental omega-3s (as opposed to dietary fish intake) is more mixed across large trials.

Dose studied

0.5–4 g — daily DHA/EPA doses studied for triglyceride and omega-3 index effects, per NIH ODS.

Context

Trials on algal DHA have generally used daily doses in the few-hundred-milligram to low-gram range over several weeks to months, primarily measuring blood omega-3 index or triglyceride levels rather than long-term cardiovascular outcomes.
