Use creatine to protect the brain against traumatic brain injuries (TBI) and their consequences, especially in cases of repeated impacts.

noli's read

The idea that creatine may support brain health is based on its key role in cellular energy metabolism (ATP). Preclinical studies on animal models (rats/mice) do indeed show a reduction in cortical damage and improved energy management following trauma. In humans, however, the evidence is more limited and primarily based on narrative reviews or pilot studies, lacking large-scale, definitive randomized clinical trials (RCTs) to confirm equivalent protection. While supplementation is considered safe and potentially useful for supporting metabolic recovery after a concussion, asserting that it preventatively "protects" the brain against permanent injury in humans is a bold extrapolation of current data. There is a consensus that creatine helps maintain cerebral energy balance, but its direct clinical efficacy in preventing second-impact syndrome remains to be established.
