Omega-3 Treatment for Concussion in Adolescents

The goal of this clinical trial is to test omega-3 fatty acid supplementation as a treatment in adolescents with a concussion. The main questions it aims to answer are: * Does supplementing with omega-3 fatty acids improve time to recovery following sport related concussion. * Does supplementing with omega-3 fatty acids improve health related quality of life following concussion. * Does supplementing with omega-3 fatty acids change post-concussion symptoms following concussion. * Does supplementing with omega-3 fatty acids change saliva concentrations of interleukin-6 following concussion. * Does supplementing with omega-3 fatty acids change saliva concentrations of cortisol following concussion. Participants will be randomized to receive either an omega-3 supplement or placebo after they have been diagnosed with a concussion. Researchers will compare the omega-3 supplement group and placebo group to see if omega-3 fatty acids, consumed as a treatment, can improve time to recovery, health related quality of life and symptom burden, and whether omega-3 fatty acids alter interleukin-6 and cortisol concentrations in saliva following a concussion.
