“Poor omega-3 fatty acid status has been linked to anxiety in the general population…..”
“Whole blood samples were obtained from 54 female collegiate athletes and analyzed for fatty acids as a part of this cross-sectional observational study.”

“Both blood and dietary omega-3 fatty acid levels are associated with general but not sport-specific anxiety in female collegiate athletes during an off-season period. Randomized trials should be conducted to evaluate the effects of omega-3 fatty acid supplementation on anxiety and mental toughness in athletes.”
