What was done

The International Society of Sports Nutrition (ISSN) reviewed published literature to establish an official position stand regarding the effects of long-chain omega-3 polyunsaturated fatty acid (ω-3 PUFA; primarily EPA and DHA) supplementation on exercise performance, recovery, immune function, and brain health in athletic and healthy populations.

What was found

The abstract provides qualitative consensus conclusions without numerical effect estimates or confidence intervals. The ISSN reports that: athletes may be at elevated risk of ω-3 PUFA insufficiency; supplementation effectively raises ω-3 levels; EPA and DHA enhance aerobic endurance capacity and cardiovascular function; supplementation does not appear to increase muscle hypertrophy in young adults; combined with resistance training, supplementation may improve strength in a dose- and duration-dependent manner; supplementation may reduce subjective post-exercise muscle soreness; supplementation positively modulates athletic immune cell responses; prophylactic supplementation may provide neuroprotective benefits for athletes exposed to repeated head impacts; supplementation is associated with improved sleep quality; and athletic data regarding gut microbiome impacts are currently lacking.

Why it matters

This document provides an official reference framework for dietitians, trainers, and sports medicine practitioners assessing when and why to recommend EPA/DHA supplementation for athletes.

Limits

The abstract outlines broad narrative consensus statements without reporting specific quantitative effect sizes, dosing ranges, or study quality assessments. Several assertions are qualified as provisional ('may'), and evidence remains limited in specific domains such as gut health.
