In recent times, there has been a surge in curiosity regarding nutritional approaches that can enhance brain health and performance. One strategy that has gained considerable attention is creatine monohydrate (CM) supplementation, known for its benefits on skeletal muscles. However, its impact on brain function, particularly cognitive processing and recovery from brain injuries, requires further exploration.
The Energy Demands of the Brain
The brain relies on creatine and phosphocreatine, similar to skeletal muscles, to maintain optimal levels of Adenosine Triphosphate (ATP) during periods of heightened energy demand. The brain accounts for approximately 20% of basal energy expenditure.
Unveiling the Potential
Research indicates that CM supplementation can elevate brain creatine levels. Studies demonstrate enhancements in cognitive processing, especially under taxing conditions like sleep deprivation or intense physical or mental exertion. These positive findings are encouraging, considering the variations in study populations and supplementation protocols.
Aiding Recovery from Mild Traumatic Brain Injury (mTBI)
CM supplementation may have advantages in mitigating the severity of, or facilitating recovery from, mTBI. Changes in energy demand, blood flow, oxygen levels, and brain creatine levels occur after mTBI. CM supplementation may ameliorate aspects such as calcium influx, nerve damage, mitochondrial dysfunction, oxidative stress, and inflammation.
Evidence from Studies
Animal studies show that CM supplementation reduces brain damage resulting from traumatic brain injuries. It also increases brain creatine levels and mitigates cognitive disruptions in humans exposed to oxygen deprivation, mimicking the effects of mTBI. Children with brain injuries who received CM supplements displayed improved cognition, communication, self-care, and reduced symptoms.
While CM's benefits for skeletal muscles are well-documented, emerging evidence suggests its potential impact on brain function and recovery from brain injuries. Positive findings in various studies, combined with the established safety profile of CM supplementation, make it a compelling strategy for individuals seeking to improve brain health and those at high risk for mild traumatic brain injury.
