Dietary EPA + DHA, via fish or supplement, can be reliably tracked using the omega-3 index (O3i), which is the relative amount of EPA + DHA in red blood cells (RBC) expressed as a percentage of total fatty acids.

Objective: This study examined the extent to which the omega-3 index (O3I; the proportion of eicosapentaenoic acid+docosahexaenoic acid in erythrocyte membranes) improved the predictive capability of PCE.

The athlete group tended to have a higher percentage of high risk/intermediate in the omega-3 index (75.7% vs. 57.9%; p=0.082) or high-risk category in the trans-fat index (9.5% vs. 0.0%; p=0.093) compared to the control group....The energy-adjusted DII negatively correlated with the omega-3 index, although n-3 PUFA intake did not correlate with the omega-3 index in either group. The present findings indicated that DII might affect omega-3 index independent of n-3 PUFAs intake in female athlete....Health care professionals and coach should consider nutritional interventions based on the omega-3 index rather than relying solely on n-3 PUFAs intake for female athletes.

Background/objectives: The Omega-3 Index (O3I), which is the total eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in erythrocytes as a percentage of total fatty acids (FAs), is associated with fish intake. O3I...

or anxiety symptoms had a lower erythrocyte concentration of arachidonic acid (20:4 n-6), (p = 0.01), total omega 6 FAs, (p = 0.03), docosahexaenoic acid (22:6 n-3) (p = 0.03), docosapentaenoic acid (22:5 n-3) (p = 0.04), eicosapentaenoic acid (20:5 n-3) (p = 0.005), total omega 3 FAs (p = 0.005), omega...-3 index (p = 0.01), compared to healthy pregnant women.

Measurements and main results: Our exposure was baseline estimated omega-3 index (eO3I), modeled both categorically in quartiles, and continuously with restricted cubic splines.

The omega-3 index has been proposed in mental health as a contributor to identify high risk patients and monitor disease advancements but the evidence on its relationship with burnout is limited....This study is meant to test the hypothesis that the omega-3 index is inversely associated with burnout levels and to discuss its potential as a biological correlate of burnout....The relationship between burnout levels and the omega-3 index was assessed through linear regression analysis. Results: We surveyed 300 subjects (94% response rate)....The mean omega-3 index was 5.75%. The depersonalization score was, on average, 11.132 points higher (95% CI [4.661; 17.603]) in individuals whose omega-3 index was lower than 4%....Discussion: An omega-3 index below 4% seems to potentially be a biological correlate of depersonalization. Our results contribute to enlarging the knowledge about burnout biological correlates, an area that has been previously signalled as underdeveloped.

Nineteen primary immunodeficient patients with predominant antibody defects (out of which fourteen with CVID) and eighteen immunocompetent participants had their blood tested in order to determine the concentration of EPA, DHA and omega-3 index values....concentration of omega-3 fatty acids such as DHA and in particular EPA (CVID: 0.86% ± 0.28% vs 1.06% ± 0.31%, p = 0.095) as compared with the control group and the differences were most evident among patients aged 30-39 (0.67 ± 0.16% vs 1.12 ± 0.12%, p = 0.025). 63% of patients with immunodeficiency had an omega...-3 index value between 4-8, compared to 39% in the control group. 37% of participants with predominantly antibody defects had an omega-3 index value > 8% (29% of all CVID group) compared with 61% of the control group....These findings suggest that primary immunodeficient patients with predominantly antibody defects tend to have lower omega-3 index values, albeit not significantly and seem to have higher cardiovascular risk than the control group.

This study in dogs had two objectives: first, to determine whether a daily supplement of marine omega-3 (EPA and DHA) would (1) increase red blood cell EPA + DHA levels (i.e., the Omega-3 Index derived from dried blood spot analysis) and (2...

Purpose of review: The Omega-3 Index (O3I) was proposed 20 years ago as not only a marker of body omega-3 fatty acid status, but more importantly, as a risk factor for fatal coronary heart disease. The purpose of this rev...
