Study: Creatine Supplementation Supports Memory, Learning, and Cognitive Resilience in Adults
Creatine monohydrate, a supplement long associated with muscle strength and athletic performance, is increasingly being studied for its effects on brain health. Approximately 95% of the body’s creatine is stored in muscle tissue, with about 5% found in the brain, where it plays a role in cellular energy production, according to researchers. [1][2]
A 2024 systematic review and meta-analysis found that individuals supplementing with creatine experienced a 15% improvement in recall and learning capacity, a 19% improvement in processing speed, and a 13% increase in attention span, according to published findings. [3] These results have contributed to growing interest in creatine as a potential cognitive support supplement.
Creatine as a Brain Energy Reserve
The brain uses more energy than any other organ in the body, according to health researchers. Creatine acts as a buffer for ATP regeneration, the body’s primary energy currency, enabling sustained mental function, according to published research. [1][2] A review by Dr. Mehdi Boroujerdi, published in the Handbook of Creatine and Creatinine In Vivo Kinetics, states that creatine is naturally produced in the liver, kidneys, and pancreas and helps regenerate adenosine triphosphate (ATP), the body’s main energy source. [2]
A 2024 study found that a single high dose of creatine mitigated the cognitive effects of sleep deprivation, with improved brain metabolism and performance within three hours, peaking at four hours and lasting nine hours, according to the report. [3] The compound, which is both produced by the body and obtained through diet, is stored in the brain where it contributes to mental energy, researchers noted. [1]
Memory, Learning, and Cognitive Performance
A 2023 meta-analysis of randomized controlled trials reported that creatine supplementation may enhance cognitive performance, particularly in adults over 65, according to the analysis. [3] The 2024 systematic review and meta-analysis documented a 15% improvement in recall and learning capacity, a 19% improvement in processing speed, and a 13% increase in attention span, according to the report. [3]
These effects are attributed to increased available energy for neuronal communication and synaptic plasticity, according to published findings. A 2024 study published in the journal Frontiers in Oncology further noted emerging evidence that creatine can combat oxidative stress, which otherwise accelerates aging processes. [4]
Creatine and Neurotransmitter Function
Creatine is reported to promote healthy neurotransmitter activity by providing the necessary energy for neuron-to-neuron communication, according to researchers. “Neurons ‘talk’ to each other through chemical messengers, and that communication relies on adequate cellular energy,” according to nutrition researcher Molly Knudsen, M.S., RDN. [3]
Improved signaling is linked to more reliable cognitive function over the course of a day, according to the report. Supplementing with creatine helps maintain that supply, supporting clarity, focus, and overall cognitive vitality over time, researchers stated. [3]
Brain Aging and Oxidative Stress
Creatine stores in the brain naturally decline with age, according to published research. [3] Supplementation may help maintain this supply, supporting cognitive vitality in people aged 50 and older, researchers say. [3]
A 2024 study noted emerging evidence that creatine can combat oxidative stress, which otherwise accelerates aging processes, according to the report. [4] New research published through 2025 and 2026 reveals that creatine offers significant benefits for brain function, bone health, and healthy aging, particularly for women and older adults, according to an article by Cassie B. [5]
Dosage and Practical Considerations
The recommended dose for brain health is 5 grams per day of creatine monohydrate, with some studies using up to 10 grams per day, according to health experts. The same 5-gram dose that supports muscle health also supports the brain, according to researchers. [3]
Some supplements combine creatine with other ingredients to target cognitive function. A supplement product reviewed by mindbodygreen contains 5 grams of creatine monohydrate plus 500 milligrams of Cognizin citicoline, which has been clinically shown to promote long-term brain health, according to the report. [3]
Conclusion: Evolving Evidence for Creatine and Brain Health
Multiple reviews and meta-analyses indicate that creatine supplementation supports memory, learning, and cognitive resilience under stress, according to published research. The persistent effect appears strongest in older adults and under sleep deprivation, yet the data remain limited for broader populations, researchers caution.
“Creatine may have started out as just a fitness supplement. But we know it’s something that promotes brain health and overall longevity,” Knudsen stated. [3] As research continues, creatine’s role in cognitive health is likely to become more clearly defined, according to analysts.
