Omega-3 fatty acids - specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) - are essential fatty acids that the body cannot produce, making dietary intake critical. Most Australians don't consume adequate omega-3s from food, making supplementation one of the most broadly beneficial health interventions available.
For athletes, omega-3s have several relevant benefits: they reduce training-induced inflammation and muscle soreness (supporting faster recovery), they support joint health (reducing the cartilage-degrading inflammatory response that high training volumes can create), they have demonstrated cardiovascular benefits (reducing blood triglycerides, improving blood pressure), and emerging research suggests EPA and DHA may directly stimulate muscle protein synthesis, enhancing the anabolic response to training.
Dosing: 2-4g of combined EPA+DHA daily for athletes. Check the label carefully - a 1000mg fish oil capsule typically contains only 300-600mg of actual EPA+DHA. You may need 3-6 capsules to hit 2-4g of EPA+DHA. Higher-concentration fish oil products (like Carlson's or Nordic Naturals) are more cost-effective at $30-50 for a 2-3 month supply. Krill oil contains omega-3s in a more bioavailable form but is significantly more expensive. Plant-based omega-3 (ALA from flaxseed) converts to EPA/DHA inefficiently and is not an adequate replacement. If you eat oily fish (salmon, mackerel, sardines) 3+ times per week, additional supplementation is less necessary.
