03 Sep 2019 --- A study published in the American Journal of Clinical Nutrition will make it possible to calculate how much omega 3 EPA and DHA is needed in studies, for subjects to reach a healthy Omega 3 Index. The index measures the level of omega 3 EPA and DHA’s in the blood, and can be used as a risk factor for heart disease, among other conditions. The researchers highlight that dose likely played a role in the relative success or failure of previous studies that have focused on omega 3 as a research variable.
