Athletes often obsess over protein for muscle growth and carbohydrates for energy. Emerging research suggests that many are overlooking two critical omega-3 fatty acids: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Insufficient levels of these fats may impact an athlete’s ability to maintain peak performance and long-term physical health. Since many individuals, including those in high-intensity training, may not meet recommended intakes, incorporating sustainable Mediterranean fish like horse mackerel and little tunny can be a practical dietary strategy. The consumption of EPA and DHA in fish is a proven way to support cardiovascular health and reduce exercise-induced inflammation.
EPA and DHA in fish for Training Adaptation, Brain Function, and Recovery
These fatty acids contribute to the physiological systems that athletes rely on most, specifically within three key areas: training adaptations, brain function, and recovery support.
Research indicates that EPA and DHA support endurance in sports such as cycling and running. Furthermore, consistent intake may improve neuromuscular activation and support the body’s adaptation to resistance training. Moreover, these nutrients go beyond physical benefits. The high concentration of EPA and DHA in fish has been shown to enhance brain function and protect against cognitive decline. Studies on soccer players and amateur athletes show that consistent intake of EPA and DHA improves reaction time, efficiency, and mood while significantly reducing fatigue.
In the context of recovery, these fatty acids are particularly beneficial. EPA and DHA in fish can help manage injuries and reduce muscle soreness. These nutrients help athletes maintain muscle mass during phases of immobilisation, such as when sidelined with a leg injury.
Addressing the Omega-3 Index Gap
Understanding nutrient levels is a key step in optimising health. The omega-3 index measures EPA and DHA levels in your red blood cells. While the optimal percentage for peak performance is 8% or higher, most professional and amateur athletes currently range between 4% and 6%.
Relying solely on plant-based sources (ALA) to close this gap is often inefficient, as the human body has a limited capacity to convert ALA into the more active EPA and DHA forms. Therefore, one of the more direct ways to support these levels is through dietary adjustments. EPA and DHA in fish offer great potential in supporting brain health, muscle preservation, and training efficiency, making these sustainable Mediterranean fish an essential addition to an athlete’s diet.
Putting EPA and DHA into Practice
EPA and DHA are key nutrients that support athletic performance, recovery, and cognitive function, yet they are often under-consumed. Including sustainable Mediterranean fish such as the horse mackerel and the little tunny in your diet, is a simple and effective way to help close this gap.
