Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Eicosapentaenoic acid (EPA) is an omega-3 polyunsaturated fatty acid commonly found in fish oil. There is some scientific evidence suggesting that EPA may support the respiratory system, particularly in conditions characterized by inflammation, such as asthma and chronic obstructive pulmonary disease (COPD). EPA has anti-inflammatory properties and can modulate the production of inflammatory mediators like leukotrienes and prostaglandins, which play a role in airway inflammation.

Several clinical studies and meta-analyses have explored the effect of omega-3 supplementation (including EPA) in respiratory diseases. Some trials have reported modest improvements in lung function and reductions in markers of airway inflammation in asthma patients, especially in populations with diets low in omega-3 fatty acids. However, the overall evidence is mixed: not all studies have demonstrated significant clinical benefits, and the magnitude of effect tends to be small. In COPD, the evidence is similarly inconclusive, with some studies suggesting reduced exacerbations or improved quality of life, but others showing no benefit.

Overall, while there is a plausible scientific rationale and some supporting evidence for EPA in respiratory health, the clinical effectiveness is not robustly established. EPA is not considered a primary therapy for respiratory diseases, but may be used as an adjunct in specific cases. Therefore, the evidence rating is moderate to low (2 out of 5).
