Estimated daily EPA + DHA
— mg/day
Enter your details above.
How it works: research suggests it takes roughly 370 mg/day of EPA + DHA to raise the Omega-3 Index by 1 percentage point over about 4–5 months (Walker et al., 2019), with wide individual variation. This is an educational estimate, not a personalised medical recommendation — discuss any change with your GP, and the only way to know your real level (and whether it's working) is to test and retest.
