Creatine is often discussed for strength and exercise performance. But because it also plays a role in how cells manage energy, people are asking another question: Could creatine help with concussion recovery?
There’s a reasonable biological idea behind the question. After a concussion, the brain may have difficulty meeting its energy needs. Creatine helps cells manage short-term energy demands, so researchers have explored whether supplementation could support recovery.
But a promising idea isn’t the same as a proven treatment. Here’s what the research currently tells us, and how I think about creatine in the context of individualized concussion care.
Why are researchers interested in creatine after concussion?
Creatine is stored in the body as creatine and phosphocreatine. Together, they help cells quickly replenish ATP, a molecule used for cellular energy. This energy system is present in muscle and brain tissue.
A concussion can disrupt the brain’s usual energy balance. That gives researchers a reason to study creatine: could increasing available creatine help the brain manage some of the energy demands that follow an injury?
That’s a plausible mechanism, but it doesn’t mean that taking creatine has been shown to restore brain energy or speed recovery in people with concussion. The US Department of Defense’s Traumatic Brain Injury Center of Excellence notes that the ideal dose and duration are unknown, and that there are no clinical guidelines for using creatine to manage or prevent TBI. health.mil
What have human studies found?
The early human research often discussed online involved children and adolescents with traumatic brain injury.
In a small, open-label pilot study, 39 patients aged 1 to 18 received creatine for six months. The researchers reported improvements in several outcomes, including post-traumatic amnesia and measures of function. The study is interesting, but its design and participants limit how confidently we can apply the findings to adults with persistent concussion symptoms. Sakellaris et al. (2006) and Sakellaris et al. (2008) reported these preliminary findings.
There is also a newer pilot trial in adults with persistent symptoms. In Denmark, 34 adults who had been experiencing symptoms for 6 to 18 months were assigned to creatine, placebo, or usual care. The creatine group took 5 grams daily for seven weeks. The study found no statistically significant difference in symptom scores between the creatine, placebo, and usual-care groups. The trial was small, so it cannot settle the question—but it does not establish creatine as an effective treatment for persistent post-concussion symptoms. Trial record: NCT06644131. ICH GCP
So, can creatine help with concussion recovery?
We don’t yet know. The biological rationale is worth studying, and the early findings are intriguing. But the human evidence is still limited, and the more recent adult pilot did not show a statistically significant benefit.
That leaves room for a thoughtful clinical conversation, but not for promises that creatine will clear brain fog, reduce headaches, or shorten recovery. Creatine is not a replacement for an assessment, a recovery plan, or care directed at the specific factors contributing to someone’s symptoms.
Concussion recovery is rarely a one-supplement problem. Sleep, nutrition, exertion tolerance, headache, neck symptoms, mood, medications, and other health factors may all be relevant. The useful question is not just “Could creatine help?” It’s also “Does it make sense for this person, given their health, goals, and full recovery picture?”
Is there a standard creatine dose for concussion?
There is no established creatine dose for concussion recovery. The doses are mixed, with 5-gram daily dose used in the adult pilot and a much higher dose used in the earlier paediatric study. We still have a lot to learn.
If you’re considering creatine, talk it through with a qualified healthcare professional who can consider your medical history, medications, and other supplements. This is especially important if you have kidney disease or another condition that could affect supplement choice or monitoring. Creatine can also affect blood creatinine results, so let the clinician interpreting your lab work know if you take it.
What I tell patients who ask about creatine
I don’t dismiss creatine as irrelevant to concussion. The energy-related rationale is interesting, and it’s reasonable to keep following the research.
At the same time, it’s not yet a proven concussion treatment. For some people, it may be an option to discuss as one part of a broader plan. For others, other priorities may matter more. The decision should fit the person (not a supplement trend.)
If you’re dealing with lingering symptoms after a concussion, you deserve care that looks at the whole picture and helps you decide what to focus on next.
Looking for support with concussion recovery?
I work with people experiencing persistent symptoms after concussion to understand what may be contributing and build a practical, individualized care plan.

The evidence summary above draws on the two early paediatric studies, the adult pilot trial record, and the Traumatic Brain Injury Center of Excellence’s 2025 information paper. The paper summarizes the current uncertainty around dose, duration, and clinical guidance.
