New research in the International Journal Of Sports Nutrition and Exercise Metabolism has suggested that the inclusion of Omega-3 polyunsaturated fatty acids may reduce the production of inflammatory eicosanoids, cytokines and free radicals.
The new findings add to the body of knowledge already relatively well known in animals, however the effects are yet to be fully proven in humans. Mickleborough (2013) admits that too much omega-3 can have immunosuppressive effects increasing your risk of illness, but this has to be well in excess.
So by ingesting approx 1-2g per day of the Omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) at a 2:1 ratio may be beneficial to reducing exercise induced inflammation.
