Ever wish you had a bit more mental fuel to tackle the day? Creatine—a supplement popular with athletes for boosting physical performance—might also have surprising benefits for your brain. New research is examining how creatine could help with mental clarity, memory, and even mood. So, could this fitness staple be just as valuable for cognitive health? Let’s take a closer look at what the science says about creatine’s potential for brain function and mental wellness.
Why Does the Brain Need So Much Energy?
Your brain is a power-hungry organ! Although it makes up just 2% of your body weight, it burns through about 20% of your daily energy. That’s because the brain is always on—managing everything from memory to problem-solving to keeping us focused. This constant activity means the brain needs a steady energy supply, and creatine can help meet this demand.
How? Creatine helps the body produce ATP, the molecule that provides quick energy to cells. By increasing ATP stores in the brain, creatine may provide extra fuel for mental tasks, helping support memory, focus, and clarity when you need it most. So, whether you’re pulling an all-nighter or simply juggling a busy day, creatine could be a valuable brain booster.
Creatine and Cognitive Performance
Creatine and Memory
Studies show that creatine may support memory, particularly in older adults and people with lower natural levels of creatine, such as vegetarians. For example, in one study, adults aged 68–85 who took 20 grams of creatine for just seven days saw improvements in memory tasks, like remembering numbers and recalling details (1). Another study found that vegetarians who supplemented with creatine experienced improved working memory compared to those who didn’t (2). However, some studies have shown mixed results (1).
While more research is needed to confirm these benefits across all age groups, these findings hint that creatine might be a simple way to support memory—especially for older adults or anyone looking to keep their brain sharp.
Creatine for Focus During Sleep Deprivation
Struggling to stay focused after a poor night’s sleep? Sleep deprivation can drain the brain’s energy, affecting our ability to concentrate, stay positive, and make quick decisions. But research suggests that creatine supplementation may help here, too (3).
In studies, sleep-deprived participants who took creatine experienced fewer declines in cognitive performance, including quicker reaction times and better mood (4). Think of creatine as a bit of extra “mental stamina” during those long days or late nights.

Creatine’s Potential for Mood and Mental Wellness
Mental health challenges like depression and anxiety are increasingly common and often come with low energy levels in the brain. Emerging research suggests creatine could play a role in improving mood by increasing energy availability in brain cells, which may also reduce oxidative stress, a factor linked to mental health disorders.
Creatine and Depression
Studies have identified a potential link between low dietary creatine intake and an increased risk of depression. One study, for instance, found that individuals with lower creatine intake had a higher likelihood of depressive symptoms (5). Additionally, clinical studies have suggested that creatine supplementation may offer benefits as an add-on treatment to conventional antidepressants, with some studies reporting improvements in depressive symptoms when creatine was added to the treatment regimen (6). Though still early, these findings suggest creatine may offer a new option for those managing depression—especially when traditional treatments alone aren’t fully effective.
Creatine and Anxiety & PTSD
Research on creatine’s effects on anxiety and post-traumatic stress disorder (PTSD) is still limited, but some early findings are promising. For instance, studies have found that people with generalized anxiety disorder (GAD) or PTSD often have lower creatine levels in specific brain areas (7, 8). In one case, a PTSD patient reported improvements in sleep and mood after taking creatine for four weeks, even after other treatments hadn’t been effective (9). While more research is needed, creatine’s role in supporting mental health looks promising, especially for people dealing with high stress or trauma.

Creatine and Brain Injuries: Concussions and Traumatic Brain Injury
Traumatic brain injuries (TBIs), including concussions, create an intense need for brain energy to help repair damaged tissues and restore function. Following a TBI, creatine levels in the brain often decrease, which can worsen symptoms. Early studies suggest creatine supplementation might support recovery from TBI by helping replenish brain energy stores and reducing oxidative stress (1).
In a small pilot study involving children and adolescents with severe TBI, creatine supplementation was associated with improvements in symptoms like headaches, dizziness, and fatigue (1). Animal studies have shown similar benefits, including reduced brain damage after injury, which suggests creatine may help protect the brain and aid recovery (1).
Should I Take Creatine for Cognitive Health?
Creatine may be especially helpful for older adults, vegetarians, vegans, and individuals under high mental or physical stress. It is generally safe for most people when taken as directed, with the potential for mild side effects like digestive issues or water retention in some cases.
If you’re considering creatine for cognitive health, remember that individual results vary, and it’s best to consult with a healthcare provider before starting any new supplement, particularly if you have underlying health conditions. While research on creatine’s mental health benefits is promising, further large-scale studies are needed to fully understand its effects.

Conclusion
While creatine is best known for muscle support and athletic performance, it could have valuable benefits for your brain, too. From helping with memory and mental clarity to supporting mood, creatine’s potential as a supplement for mental wellness is an exciting area of study. Whether you’re looking for support with daily mental demands or seeking additional ways to manage mental stress, creatine might be a worthwhile addition to your routine.
As science continues to explore creatine’s effects on the brain, it may become an important supplement not only for physical strength but also for cognitive support and mental health. If you’re curious about adding creatine to your wellness routine, speak with a healthcare provider and explore whether it could be a good fit for your goals.
