Omega-3 EPA/DHA Target Calculator

About this calculator

Health organizations generally recommend a combined EPA + DHA (the two main marine omega-3 fatty acids) intake of around 250-500 mg per day for general heart health, while therapeutic targets for specific goals run higher — the American Heart Association suggests roughly 1,000 mg/day for people with existing heart disease, and clinical trials for triglyceride management have used 2,000-4,000 mg/day under medical supervision. Some guidance also scales the target to body weight for consistency across different-sized people.

People choosing between fish oil, algae oil or krill oil supplements use a daily target like this to figure out how many capsules or how much oil to take, since supplement labels list EPA and DHA separately in milligrams per serving rather than as a combined omega-3 total, which makes it easy to underdose without doing the addition yourself.

This calculator takes your health goal and body weight and returns a daily EPA+DHA target in milligrams to guide your supplement dosing.
