Rating (out of 5): 2

DHA (docosahexaenoic acid), an omega-3 fatty acid, has garnered scientific interest for its potential neuroprotective effects, particularly in the context of brain injuries such as concussions. Preclinical studies, mostly in animal models, have demonstrated that DHA supplementation may help reduce neuronal damage, inflammation, and oxidative stress following traumatic brain injury. DHA is an essential component of neuronal membranes, and higher membrane concentrations are thought to support membrane fluidity, synaptic function, and neurogenesis, all of which may be beneficial in the context of brain injury recovery. Some pilot human studies and small clinical trials have suggested that DHA supplementation could reduce the incidence or severity of concussions in athletes, or hasten recovery, though these findings are preliminary and not yet conclusive. The majority of evidence remains at the animal or in vitro level, with limited large-scale, high-quality randomized controlled trials in humans. No major medical guidelines currently recommend DHA as a standard treatment for concussion, and its use is considered adjunctive and experimental. In summary, while there is a growing body of scientific evidence suggesting potential benefits of DHA for supporting brain health after concussion, the current level of evidence is modest (rated 2/5), and further research is needed to confirm efficacy and optimal dosing in human subjects.
