    Creatine Monohydrate for Traumatic Brain Injury

    Creatine has the most plausible mechanism of any supplement in brain injury and one small paediatric trial with striking results that has never been replicated.

    Overview

    Creatine has the most plausible mechanism of any supplement in brain injury and one small paediatric trial with striking results that has never been replicated.

    Verdict

    Mixed evidence

    Mixed. Coherent bioenergetic rationale and one unreplicated positive paediatric trial.

    How It Works

    Traumatic brain injury produces an acute energy crisis: ATP demand rises while mitochondrial function is impaired. Creatine expands the phosphocreatine buffer, supports ATP resynthesis, and may stabilise the mitochondrial permeability transition pore.

    Dosing & Protocol

    Typical dose

    Recommended dose
    Not established; pilot paediatric TBI work used about 0.4 g/kg/day for up to 6 months. Evidence is mixed and preliminary.
    Expected timeframe
    Not established; pilot studies ran up to 6 months

    Protocol

    dose
    Not established (pilot studies ~0.4 g/kg/day)
    form
    Creatine monohydrate
    steps
    Evidence is mixed and preliminary: small open-label paediatric TBI studies reported improvements, but there is no adequately powered blinded trial,Acute and post-acute TBI care must be clinician-directed — creatine is not a treatment,If your clinician supports a trial of creatine during rehabilitation, standard 5 g/day is the conservative option rather than high per-kilogram dosing,Track function with the rehab team's validated measures, not subjective impressions

    Evidence

    What the studies say

    The bioenergetic argument for creatine in brain injury is stronger than for most supplements, because the neurometabolic cascade after concussion is fundamentally an energy-supply problem. Animal models show reduced cortical damage with creatine pretreatment. The most cited human evidence is a small open-label study in children and adolescents with traumatic brain injury reporting substantially improved outcomes on multiple domains with six months of creatine, but the trial was unblinded, small, and has not been replicated in twenty years. Broader evidence that oral creatine meaningfully raises brain phosphocreatine is mixed, with magnetic resonance spectroscopy studies showing smaller increases in brain than in muscle. Creatine is cheap and safe, and the case for trying it is reasonable, but the evidence base remains a single unreplicated study.

    Increasing creatine availability may enhance cellular metabolism and lessen injury severity when oxygen availability is compromised.

    Safety

    Caveats

    Mixed, preliminary evidence. High-dose creatine is not safety-characterised for prolonged paediatric use. Raises serum creatinine on labs; avoid in chronic kidney disease. Not for use in pregnancy without clinician oversight.

    Less likely to help if

    Unknown — no responder pattern has been established for TBI.
