Last year, GrassrootsHealth published a paper that assessed the EPA+DHA intake requirement to achieve an Omega-3 Index of 8% or higher, the optimal level for health, using YOUR omega-3 data. This analysis found that among the 265 participants who reported no fatty fish intake (to ensure no major sources of EPA+DHA input beyond supplements), ~1,300 mg/day of EPA+DHA was needed for 50% of the population to achieve an Omega-3 Index of 8%. Approximately 1,900 mg/day of EPA+DHA was needed for 90% of the population to achieve an Omega-3 Index of 8%.
Now that we have almost twice as many participants who have tested their Omega-3 Index and provided supplement intake information on their survey, we ran this analysis again to see if the results would be the same. We found the EXACT SAME results: ~1,300 mg/day of EPA+DHA was needed for 50% of the population and ~1,900 mg/day was needed for 90% of the population to achieve and Omega-3 Index of 8% (chart below).
Finding the exact same results with almost twice as many participants shows that these intake amounts are consistent and reliable. However, it is important to point out that these intake amounts are averages and there is a large amount of variability in the omega-3 status for different people with the same intake amount. Therefore, we recommend that individuals measure their Omega-3 Index and determine a personalized dose. Check out our Omega-3 calculator to help you determine the estimated dose needed for you to reach your desired Omega-3 Index.
Are you getting enough nutrients to achieve recommended levels?
Make sure you know your vitamin D level, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L! Through GrassrootsHealth Nutrient Research Institute, you can also test your essential elements magnesium, copper, zinc and selenium, toxins such as lead, mercury and cadmium, as well as your omega-3 levels, inflammation levels and thyroid stimulating hormone (TSH) level. Find out your levels today! Log on to the test selection page (click the link below) to get your tests and see for yourself if your levels can be improved.
Make sure you track your results before and after, about every 6 months!

How can I track my nutrient intake and levels over time?
To help you track your supplement use and nutrient levels, GrassrootsHealth has created the Personal Health Nutrient Decision System called
For each specific supplement, you can track what days you take it, how much, and many other details. This will help you know your true supplemental intake and what patterns of use work for you to reach and maintain optimum nutrient levels. Check it out today!
How Can You Use this Information for YOUR Health?
Having and maintaining healthy vitamin D and other nutrient levels can help improve your health now and for your future. Measuring is the only way to make sure you are getting enough!
STEP 1 Order your at-home blood spot test kit to measure vitamin D and other nutrients of concern to you, such as omega-3s, magnesium, essential and toxic elements (zinc, copper, selenium, lead, cadmium, mercury); include hsCRP as a marker of inflammation or HbA1c for blood sugar health
STEP 2 Answer the online questionnaire as part of the GrassrootsHealth study
STEP 3 Using our educational materials and tools (such as our dose calculators), assess your results to determine if you are in your desired target range or if actions should be taken to get there
STEP 4 After 3-6 months of implementing your changes, re-test to see if you have achieved your target level(s)
