Creatine is widely known as a powerful supplement for athletes and fitness enthusiasts looking to boost muscle strength and performance. However, in recent years, scientific research has explored its potential benefits beyond muscle health—particularly its impact on the brain. This has led many to ask, does creatine increase intelligence? In this article, we will dive into what creatine is, how it affects brain function, and whether it truly enhances cognitive abilities such as intelligence.
What Is Creatine?
Creatine is a naturally occurring compound found mainly in muscle cells, but also in the brain. It helps produce energy by regenerating adenosine triphosphate (ATP), the body’s primary energy molecule. While creatine is mostly celebrated for its ability to improve physical performance, the brain also relies heavily on ATP for proper function.
Because the brain consumes a significant amount of energy—about 20% of the body’s total energy usage—it makes sense that creatine could influence mental processes. The connection between creatine and brain energy has sparked research into whether creatine supplements can help enhance cognitive function, including memory, focus, and intelligence.
How Does Creatine Work in the Brain?
The brain requires constant energy to maintain functions like memory formation, learning, and decision-making. ATP powers these processes, and creatine plays a crucial role in replenishing ATP quickly during periods of high demand.
When creatine levels are sufficient, the brain can maintain energy supply more effectively, especially during stressful conditions like sleep deprivation or intense mental activity. This leads to better cognitive performance and reduces mental fatigue.

The term “intelligence” covers a broad range of mental capabilities such as problem-solving, reasoning, memory, and learning. While creatine is unlikely to make someone instantly smarter or increase IQ in a dramatic way, several scientific studies have demonstrated that creatine supplementation can improve certain aspects of cognitive function that contribute to intelligence.
Key Research Findings on Creatine and Intelligence
- Improved Working Memory: A landmark study from the University of Sydney in 2003 found that healthy young adults who took 5 grams of creatine daily for six weeks showed significant improvements in working memory and intelligence test performance. Working memory is essential for reasoning and problem-solving.
- Reduced Mental Fatigue: Research on sleep-deprived individuals has shown that creatine can help reduce the cognitive decline that often comes with lack of sleep. For example, military personnel taking creatine supplements experienced less decrease in cognitive function during extended wakefulness.
- Enhanced Cognitive Speed in Vegetarians: Vegetarians and vegans, who typically have lower natural creatine levels due to the absence of meat in their diets, showed notable improvements in memory and mental processing speed after creatine supplementation.
These findings suggest that creatine can enhance mental performance, especially in tasks that require short-term memory and quick thinking, which are components of what many consider intelligence.
Who Benefits Most From Creatine’s Cognitive Effects?
Not everyone may experience the same cognitive boost from creatine supplementation. Those who could benefit the most include:
- Students and professionals who need sharp focus and strong memory during demanding mental tasks.
- Older adults facing age-related cognitive decline.
- People experiencing mental fatigue or sleep deprivation.
- Vegetarians and vegans, due to naturally lower creatine stores.
- Anyone seeking to optimize both physical and mental performance.
How to Use Creatine for Brain Benefits
The dosage recommended for cognitive benefits is similar to that used in fitness:
- Dosage: 3-5 grams per day of creatine monohydrate.
- Timing: Consistency is more important than exact timing; take it daily.
- Duration: Benefits tend to accumulate over a few weeks of regular supplementation.
Creatine monohydrate is the most researched and affordable form available.
Safety and Side Effects
Creatine is generally considered safe when taken at recommended doses. Side effects are rare but can include mild gastrointestinal discomfort. It is advisable to consult a healthcare provider before starting creatine, especially if you have pre-existing kidney conditions or other health concerns.
Final Verdict: Does Creatine Increase Intelligence?
While creatine may not increase intelligence in the traditional sense of raising your IQ score overnight, it does improve key cognitive functions such as memory, focus, and mental endurance. These improvements can translate to better problem-solving skills and faster thinking—important components of practical intelligence.
In summary, creatine acts as a brain energy enhancer that helps you think more clearly, reduce mental fatigue, and improve cognitive performance, particularly under stress or sleep deprivation.
If you are looking for a safe, well-studied supplement to support brain function, creatine is worth considering—not just for muscle gains but also for a mental edge.
