Fish oil supplementation reduced inflammation by 50% and increased anti-inflammatory markers by 100% in boys with Duchenne muscular dystrophy.

This double-blind, placebo-controlled study showed that supplementation with 2.9 grams of omega-3 fatty acids per day for 6 months has a significant effect on the immune system by decreasing inflammatory biomarkers by 50% and increasing anti-inflammatory markers by 100%. Inflammation is considered an important factor in disease progression. Although no clinical endpoints were measured in the study, the robust effects on the immune system would almost certainly improve some symptoms of muscular dystrophy.
