Today At A Glance:
Creatine is widely used for muscle strength and athletic performance, but recent studies suggest it might also benefit brain health. This article explores the scientific evidence behind using creatine for traumatic brain injuries (TBI), concussions and general brain health.
Today’s Newsletter Is Brought To You By Momentous
Despite a healthy diet, many of us lack essential nutrients. I've added Momentous Creatine, Omega-3, and Protein to my daily regimen to support my overall health, from cognitive function to reducing inflammation.
That’s why I partnered with Momentous for all of my supplements and I choose this brand for my clients too.
The best part?
Momentous has by far the most rigorous commitment to quality, demonstrated by expert partnerships and strict third-party testing, making their products a reliable choice upheld by top athletes.
Neuro Athletes,
I recently shared a reel to Instagram about the impact of creatine on brain health and its potential as a neuroprotective agent, particularly in the context of traumatic brain injuries (TBI) and concussions. The response was overwhelming, garnering nearly 800,000 views and sparking over 600 comments. Given the interest and some of the questions raised, I wanted to delve deeper into the science of creatine and its effectiveness for neuroprotection.
Creatine is not just a supplement for athletes but a critical molecule for energy management in the brain. Typically synthesized in the liver, creatine plays a crucial role in maintaining cellular energy through ATP regeneration.
This is particularly vital in the brain, which consumes about 20% of the body's energy despite making up only 2% of its mass. There is a robust and compelling body of evidence supporting the ergogenic and therapeutic role of creatine supplementation in muscle. Beyond these well-described effects and mechanisms, there is literature to suggest that creatine may also be beneficial to brain health (e.g., cognitive processing, brain function, and recovery from trauma).
Protection Against Physical Trauma
Creatine's role in neuroprotection, particularly against physical trauma such as concussions commonly experienced in contact sports, is backed by several clinical studies. The mechanism behind this protection is linked to creatine's ability to enhance cellular energy reserves through increased phosphocreatine levels, which in turn support the maintenance and rapid restoration of ATP during and after traumatic incidents.
This ATP buffering capacity is crucial, as it helps maintain cellular function and integrity under stress, potentially reducing the severity of injury outcomes such as cellular apoptosis (programmed cell death) and axonal damage.
Potential in Neurodegenerative Diseases
In the realm of neurodegenerative diseases, creatine shows significant promise due to its mitochondrial stabilization properties. Neurodegenerative disorders such as Parkinson's and Alzheimer's disease are characterized by mitochondrial dysfunction and an associated decline in cellular energy metabolism.
Creatine supplementation has been observed to stabilize mitochondrial membranes and enhance their function, which can prevent the decline in ATP production that is often noted in these conditions. Additionally, creatine exerts antioxidant effects, reducing oxidative stress within the brain, which is a contributing factor in the progression of neurodegenerative diseases.
Preliminary preclinical studies have documented the protective effects of creatine in models of Parkinson's disease, where it appears to inhibit the loss of dopaminergic neurons.
Similarly, in Alzheimer's research, creatine is being investigated for its potential to reduce amyloid-beta toxicity—a hallmark of Alzheimer's pathology. Ongoing clinical trials are expected to provide more robust data, potentially establishing creatine as a standard adjunct therapy in the management of these disorders by enhancing overall neuronal health and functional connectivity.
Dr. Darren Candow's Insights on Creatine and TBI
On the Neuro Experience podcast, Dr. Darren Candow provided valuable insights into how creatine could benefit individuals with TBI or concussion. He highlighted several key points:
Brain Energy Utilization: The brain's high energy demand means it naturally synthesizes creatine, maintaining stable creatine levels under normal conditions. However, reduced creatine levels are common in individuals with TBI or neurological conditions like depression.
Supplementation Benefits: Supplementing creatine might restore brain creatine levels to normal, potentially speeding up recovery. A notable study involved children with TBI who were administered creatine shortly after injury, showing significant improvements in health measures like speech and self-care over six months.
Research Challenges: Determining optimal dosing and the timing of supplementation relative to injury remains a challenge. In animal models, pre-injury creatine supplementation has shown benefits, suggesting a similar approach might be beneficial in humans.
Ongoing Research and Opinions
Dr. Candow also discussed the difficulties in conducting human trials, where ethical considerations limit the ability to pre-designate individuals for creatine supplementation before potential head injuries. Nevertheless, preliminary data, especially from studies involving children and athletes, supports the notion that creatine supplementation can aid recovery post-concussion without adverse effects.

Thank you sharing and once again emphasising the importance of Creatine. I am father of Special kid. Was just thinking if any research is initiated where creatine as a supplement is considered to be for brain development in special kids.
