Omega-3 Polyunsaturated Fatty Acid Supplementation for Reducing Muscle Soreness after Eccentric Exercise: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

There is low-quality evidence that n-3 PUFA supplementation does not result in a clinically important reduction of muscle soreness after eccentric exercise. Isometric muscle soreness and range of motion were not improved by n-3 PUFA supplementation either (low-quality evidence). To further elucidate the overall role of n-3 PUFA on muscle damage in this area, large-scale RCTs are still needed.
