What is Neuroprotection?
Neuroprotection refers to any mechanism, strategy, or substance that preserves the structure and function of neurons (brain and nerve cells) against damage, degeneration, or death.
Neurons are particularly vulnerable to energy deficits, oxidative stress, and excitotoxicity because they have high metabolic demands and limited regenerative capacity.
Neuroprotective strategies aim to maintain neuronal energy supply, reduce oxidative damage, prevent toxic calcium influx, and support mitochondrial function.
Both pharmaceutical agents and nutritional compounds are studied for their neuroprotective potential.
Relevance to Creatine Supplementation
Creatine has emerged as a notable nutritional neuroprotectant.
The brain, despite being only about 2% of body weight, consumes approximately 20% of the body’s energy.
The creatine-phosphocreatine system operates in brain tissue just as it does in muscle — buffering ATP levels and maintaining energy homeostasis through the creatine kinase reaction.
Research has shown that creatine supplementation can improve cognitive performance under conditions of sleep deprivation and mental fatigue, likely by supporting brain energy reserves.
Animal studies demonstrate creatine’s ability to reduce damage from traumatic brain injury, and preliminary human research is encouraging.
For the ageing brain, creatine’s dual role as an energy buffer and antioxidant makes it a compelling supplement for long-term cognitive health.
