Omega-3 supplementation lowered total salivary cortisol output throughout an acute stressor (p=0.04). Specifically, supplementation with 2.5 g/d of omega-3 resulted in 19% lower total salivary cortisol throughout the stressor compared to the placebo group (p=0.01), but supplementation with 1.25 g/d of omega-3 did not affect cortisol levels compared to placebo group (p=0.29). Error bars are 95% confidence interval.
