 is one of the most common and prevalent problems worldwide affecting over 300 million individuals.

There is some evidence from observational and intervention studies to suggest a beneficial effect of n-3 PUFA in inflammatory diseases, specifically 
asthma. Marine-based n-3 PUFA have therefore been proposed as a possible complementary/alternative therapy for asthma.

The proposed anti-inflammatory effects of n-3 
fatty acids may be linked to a change in cell membrane composition. This altered membrane composition following n-3 fatty acid supplementation (primarily EPA and DHA) can modify lipid mediator generation via the production of eicosanoids with a reduced inflammatory potential/impact.

A recently identified group of lipid mediators derived from EPA including E-series resolvins are proposed to be important in the resolution of inflammation. Reduced inflammation attenuates the severity of 
asthma including symptoms (dyspnoea) and exerts a bronchodilatory effect.

There have been no major health side effects reported with the dietary supplementation of n-3 
fatty acids or their mediators; consequently supplementing with n-3 fatty acids is an attractive non-pharmacological intervention which may benefit asthma.
