The Role of Nutritional Supplements in the Treatment of Sport-Related Concussion.

There is ongoing interest in the use of nutritional supplements for the prevention and treatment of sports-related concussions. While many athletes and clinicians incorporate vitamins and supplements into concussion recovery plans, human-based studies specific to sports concussion remain limited. This article reviews the most current evidence regarding supplements with emerging data in concussion management, including docosahexaenoic acid and fish oil, branched-chain amino acids, melatonin, magnesium, and riboflavin. Other supplements such as probiotics, vitamins C, D, and E, and taurine are discussed based on findings in animal models and moderate-to-severe traumatic brain injury. Further research is needed to clarify clinical utility.
