Creatine is best known as a sports supplement that boosts strength and muscle growth, but its role in brain health is now gaining serious attention. So what are the benefits of creatine for brain health?
Beyond the gym, creatine for women and men supports energy production in the brain, helps protect neurons from stress, and may even improve memory, mood and mental performance.
In fact, your brain requires a tremendous amount of energy, consuming about 20 percent of the body’s total energy despite making up only 2 percent of body weight. Creatine helps fuel this demand, making it a key player not only for physical performance, but also for cognitive function and mental well-being.
If you’ve ever wondered whether creatine for brain health is worth considering, here’s what science has to say.
How creatine works in the brain
Creatine acts as an energy buffer by replenishing adenosine triphosphate (ATP), the primary energy currency of cells. In the brain, ATP is critical for fueling neurotransmitter release, maintaining focus and supporting memory formation.
When ATP runs low, cognitive performance can decline. Supplementing with creatine increases the phosphocreatine pool in the brain, which helps stabilize energy levels during times of stress, sleep deprivation or intense mental effort.
This energy-enhancing effect is why researchers have studied creatine for brain health as a potential aid for memory, mood disorders, neurodegenerative conditions and even brain injury recovery.
Thus, creatine contributes to brain health by maintaining energy balance, serving as a rapid phosphocreatine reservoir to regenerate ATP, the brain’s energy currency. This energy buffering is critical for neurons under stress, during aging or intense cognitive activity .
Benefits of creatine for brain health
1. May improve memory and learning
Creatine helps supply the hippocampus with extra energy, which may enhance short-term recall, learning capacity, and even verbal working memory in both young adults and older adults.
Studies show that creatine supplementation can improve short-term memory and working memory, particularly in individuals under mental stress or sleep deprivation. By providing extra energy to brain cells, creatine helps support the hippocampus, the brain’s memory hub.
Several human studies have indicated that creatine supplementation can enhance short-term memory and working memory, particularly in vegetarians, who often have lower baseline creatine stores.
2. Supports mental performance during stress
Creatine has been found to enhance cognitive function during periods of oxygen deprivation, fatigue or sleep loss. For example, research has revealed that creatine supplementation may help maintain reaction time and decision-making ability in high-pressure or stressful environments.
By maintaining ATP levels during fatigue or oxygen deprivation, creatine can help preserve decision-making speed, accuracy and focus in high-pressure situations. That means taking creatine for brain health may support cognitive processing under stressors like sleep deprivation, aging or even mild brain injury by mitigating energy deficits.
3. May reduce symptoms of depression
Creatine supports neurotransmitter balance and cellular energy metabolism, which may reduce depressive symptoms, especially when used alongside conventional treatments.
Low brain energy metabolism has been linked to mood disorders, including depression. Creatine’s ability to support cellular energy could help regulate neurotransmitter systems tied to mood.
4. Protects against neurological decline
Creatine’s neuroprotective properties make it a promising supplement for age-related brain changes. Some studies have indicated that creatine may help slow progression or improve outcomes in neurodegenerative conditions by reducing oxidative stress and maintaining mitochondrial function.
A pilot study in Alzheimer’s patients, for instance, showed promising results when it comes to creatine for brain health. Daily creatine intake raised brain creatine by about 11 percent in participants and improved working memory, fluid cognition, list sorting and global cognitive measures.
5. Aids recovery after brain injury
By replenishing brain energy stores and limiting cell damage, creatine supplementation may support better outcomes after concussions or traumatic brain injuries. Because creatine enhances ATP availability and reduces cell damage from oxidative stress, it may aid recovery.
While research is still emerging, preliminary evidence suggests taking creatine for brain health could help protect neurons and improve long-term outcomes.
6. May boost intelligence and reasoning
Clinical studies have found that creatine can enhance performance on intelligence and reasoning tests, particularly tasks requiring problem-solving and abstract thought. In a double-blind, placebo-controlled crossover study, five grams per day of creatine for six weeks significantly improved performance on intelligence tests (Raven’s Advanced Progressive Matrices) and working memory tasks in vegetarian and omnivore subjects, for example.
7. Can combat mental fatigue
Supplementing with creatine for brain health has been shown to lower feelings of mental exhaustion during prolonged cognitive tasks, likely due to improved cerebral energy supply.
A study published in Neuroscience Research, for instance, found that supplementing with eight grams a day of creatine for five days reduced mental fatigue during sustained mental tasks and improved cerebral oxygen utilization, suggesting enhanced mental endurance.
8. May improve processing speed and attention
Evidence suggests creatine enhances reaction time, attention span and processing speed, especially in situations of cognitive stress or aging. A 2025 meta-analysis across 16 randomized, controlled trials found significant positive effects of creatine on memory, attention time and processing speed.
However, it did not seem to have an effect on executive function or overall cognition. Research continues to evaluate just how effective creatine for brain health is overall, but overall, the evidence suggests it can really help improve cognitive skills.
Who should take creatine for brain health?
Taking creatine for brain health may benefit:
Students or professionals seeking sharper memory and focus
Older adults concerned about age-related cognitive decline
Individuals struggling with depression or low mood (as part of a broader treatment plan)
Athletes, military members or shift workers exposed to sleep deprivation or stress
Those recovering from brain injury or neurological stress (with medical guidance)
It also may benefit any individuals who:
Want sharper memory, reasoning and mental stamina
Face mental fatigue or cognitive stress (e.g., sleep deprivation, high-stakes tasks)
Are older adults or concerned about age-related cognitive decline
Have or are at risk for neurodegenerative conditions like Alzheimer’s (under medical advice)
Follow vegetarian or vegan diets, due to lower baseline creatine levels
As you can see, creatine is not only for athletes. It may be an accessible, safe and effective supplement for anyone wanting to support long-term brain health.
How to use
For brain health, creatine is typically taken in the same form used for sports performance: creatine monohydrate.
Standard dosage is typically three to five grams daily
Loading phase (optional): 20 grams per day, divided into four doses, for five to seven days, then continue with three to five grams daily
Best taken with water or a meal that contains carbohydrates and protein to improve absorption
Most studies on cognition have used three to five grams daily, which appears safe for long-term use. You can also consume foods high in creatine to help meet appropriate levels.
Risks and side effects
Creatine is considered one of the safest and most well-researched supplements. Still, some potential side effects include:
Mild bloating or water retention
Digestive upset when taken in high doses
Possible strain on kidney function in people with pre-existing kidney disease (though studies show creatine is safe for healthy individuals)
To reduce side effects, stick with the recommended daily dose, and choose a high-quality creatine monohydrate supplement.
High doses or pre-existing kidney issues warrant medical consultation. There are occasional reports of side effects like night sweats. Always monitor and consult your doctor if concerned.
