Omega-3 Status Among GrassrootsHealth Participants

Published on July 23, 2020

Omega-3s are a healthy type of fat that comes in multiple forms. Omega-3s can be found in fish (EPA and DHA) and in plant oils such as flaxseed and soybean (ALA). The omega-3s found in fish (EPA and DHA) have been linked to the most health benefits. These benefits include a lower risk of cardiovascular disease, dementia, depression, asthma, inflammation, and cancer. These omega-3s can also help treat symptoms of lupus, arthritis, and dry eye disease. While ALA from plant oils can be converted to EPA and DHA, this happens at a very low level.

Since mid-2017, GrassrootsHealth has offered a home blood spot test for the Omega-3 Index, a measurement of the amount of EPA and DHA in red blood cell (RBC) membranes. This measurement reflects long-term (about four months) intake of EPA and DHA from food and supplements. Evidence suggests that achieving an Omega-3 Index of at least 8% is optimal for health whereas an index of less than 4% is deficient, particularly as it relates to cardiovascular disease.

What are the Omega-3 Index levels among GrassrootsHealth Participants?

Among the 2,777 participants who tested their Omega-3 Index, the average index was 5.7%. Almost one-fifth (18%) of participants have an Omega-3 Index of 8% or higher; 27% have an index between 6.0% and 7.9%, 45% have an index between 4.0% and 5.9%, and 10% have an index less than 4%.

Additionally, among those who completed two or more tests, 71% of those with an Omega-3 Index less than 8% increased their index after their first test. This indicates that when individuals are provided with information about their health, they are empowered to make changes and to take charge of their own health.

Have you measured your Omega-3 Index?

After you receive your Omega-3 Index results, we encourage you to use the Omega-3 Calculator to determine an estimated amount of how much more EPA+DHA you will need to reach 8% (or other desired goal). EPA+DHA is found in fish and many omega-3 supplements, but be sure you check how much EPA+DHA is in the specific types of fish you eat and the omega-3 supplements you take.
