The Omega-3 Index is defined as erythrocyte eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and represents an individual's status in these two marine omega-3 fatty acids. A target range of 8 to 11% has been suggested, because values below predispose to cardiovascular events, especially sudden cardiac death, as well as to suboptimal brain function, like prolonged reaction times or even depression. Compared with the general population, elite athletes have an increased incidence of… 
The Omega-3 Index in National Collegiate Athletic Association Division I Collegiate Football Athletes.
TLDR
The data indicate that football athletes may be deficient in the ω-3 FAs DHA and EPA, as measured by the Omega-3 Index, expressed as a percentage of total fatty acids.
Erythrocyte Omega-3 Fatty Acid Content in Elite Athletes in Response to Omega-3 Supplementation: A Dose-Response Pilot Study
Introduction Supplementation of Omega-3 fatty acids (n-3FA) in athletes is related to the anti-inflammatory and/or antioxidant effect and consequently its action on all the processes of tissue
Dietary and Biological Assessment of the Omega-3 Status of Collegiate Athletes: A Cross-Sectional Analysis
TLDR
Overall, sub-optimal ω-3 FA status was observed among a large, geographically diverse group of male and female NCAA Division I athletes, and the findings may inform interventions aimed at improving ψ-3FA status of collegiate athletes.
Dietary and Biological Assessment of Omega-3 Status of Collegiate Athletes: A Cross-Sectional Analysis
TLDR
Sub-optimal ω-3 FA status was observed among a large, geographically diverse group of male and female collegiate athletes, and these findings may inform interventions aimed at improving ψ-3FA status of collegiate athletes.
Omega-3 Fatty Acids for Sport Performance—Are They Equally Beneficial for Athletes and Amateurs? A Narrative Review
TLDR
Several studies suggest a potentially beneficial effect of EPA/DHA on performance by improved endurance capacity and delayed onset of muscle soreness, as well as on markers related to enhanced recovery and immune modulation.
Krill-Oil-Dependent Increases in HS-Omega-3 Index, Plasma Choline and Antioxidant Capacity in Well-Conditioned Power Training Athletes
TLDR
Krill oil can be used as a nutritional strategy for increasing the HS-Omega-3 Index, recover choline concentrations and address oxidative stress after intense power trainings.
Omega-3 Index and AA/EPA Ratio as Biomarkers of Running-related Injuries: An Observational Study in Recreational Runners.
AbstractThe aim of this study was to examine the association between polyunsaturated fatty acids (PUFA) biomarkers, such as omega-3 (ω-3) index and arachidonic acid (AA; 20:4 ω-6)/eicosapentaenoic
Relationship Between Distance Run Per Week, Omega-3 Index, and Arachidonic Acid (AA)/Eicosapentaenoic Acid (EPA) Ratio: An Observational Retrospective Study in Non-elite Runners
TLDR
It is suggested that distance running training and its weekly volume may negatively contribute to changes of the ω-3 index and AA/EPA ratio.
Intake of Calanus finmarchicus oil for 12 weeks improves omega-3 index in healthy older subjects engaging in an exercise programme
TLDR
Data provide first evidence that wax ester-bound n-3 PUFA from CO can significantly increase the O3I despite relatively low EPA + DHA amounts.
Evaluating the effect of a fish oil supplement on the Omega-3 Index of three professional cyclists competing in the Tour de France: a case study.
TLDR
It is demonstrated that an elite cyclist, consuming 1-2 daily fish oil capsules, can achieve and maintain a high O3I, in the favour of cardio-protection and anti-inflammation during arduous competition.

Omega-3 index and cardiovascular health.
TLDR
In epidemiologic findings, higher blood levels of EPA + DHA were consistently associated with a lower risk for the endpoints mentioned, and incorporating the Omega-3 Index into trial designs by recruiting participants with a low Omega- 3 Index will make more efficient trials possible and provide clearer answers to the questions asked than previously possible.
Omega-3 Polyunsaturated Fatty Acids in Physical Performance Optimization
TLDR
The human data are inconclusive as to whether omega-3 PUFA supplementation at this dosage is effective in attenuating the inflammatory and immunomodulatory response to exercise and improving exercise performance, and attempts should be made to establish an optimal omega- 3 fatty-acid dosage to maximize the risk-to-reward ratio of supplementation.
Effect of Omega-3 and Policosanol Supplementation on Attention and Reactivity in Athletes
Objective: The purpose of this study was to determine the effect of omega-3 fatty acids and policosanol supplementation on the cognitive processes involved in the control of reactivity in karateka
Greater erythrocyte deformability in world-class endurance athletes.
TLDR
Examination of factors that contribute to increased RBC turnover in athletes may help to understand the mechanisms that cause RBC aging and provide further evidence that the turnover of RBCs in endurance athletes is higher than in the general population.
Fish Oil Reduces Heart Rate and Oxygen Consumption During Exercise
TLDR
This study indicates that FOs may act within the healthy heart and skeletal muscle to reduce both whole-body and myocardial O2 demand during exercise, without a decrement in performance.
Altered plasma and erythrocyte phospholipid fatty acid profile in elite female water polo and football players.
TLDR
The results indicate that long-term, intense physical training significantly affects FA status of plasma and erythrocyte phospholipids in women and the type of regular training may contribute to the altered metabolism of FA.
Red blood cell omega-3 fatty acid levels and neurocognitive performance in deployed U.S. Servicemembers
TLDR
The finding that EF and CF were positively related to HS-Omega-3 Index® suggests that improving omega-3 status through an increase in omega- 3 intake may improve neurocognitive performance and confer an element of resilience to poor sleep.
Omega‐3 fatty acid supplementation does not improve maximal aerobic power, anaerobic threshold and running performance in well‐trained soccer players
TLDR
The results do not support the hypothesis that endurance athletes can improve maximal aerobic performance by omega 3‐fatty acid supplementation and Red blood cell osmotic fragility did not change.
Red blood cell omega-3 fatty acid levels and markers of accelerated brain aging
TLDR
Lower RBC DHA levels are associated with smaller brain volumes and a “vascular” pattern of cognitive impairment even in persons free of clinical dementia.
