Is Creatine Good for More Than Just Athletic Performance?
Yes. A narrative review of the literature found that creatine supplementation offers meaningful benefits well beyond sports, including improved cognitive function, reduced fatigue, and potential support for conditions like muscle wasting, neurodegenerative diseases, and chronic fatigue syndrome. Women, vegans, and people with certain clinical conditions may stand to benefit the most.
Most people associate creatine with bodybuilders and sprinters. It is one of the most widely studied sports supplements in the world, known for boosting short-term power by increasing the body’s stores of phosphocreatine, a molecule that helps regenerate ATP, the energy currency of your cells. But this review pulls together evidence showing that creatine’s benefits extend far beyond the gym. Populations that tend to have naturally lower creatine levels, such as women and people who eat plant-based diets, may gain the most from supplementation. And emerging research suggests creatine could play a role in managing serious medical conditions.
Dr. Kumar’s Take
I have been interested in creatine for a while because it is one of those rare supplements where the safety and performance data are genuinely strong. What fascinated me about this review is how it connects the dots between different populations. Women have lower baseline creatine in their muscles than men. Vegans and vegetarians get almost no creatine from their diet because it comes primarily from meat and fish. And people with conditions like sarcopenia or neurodegenerative diseases often have impaired energy metabolism. In all three cases, the logic is the same: if your creatine stores are low, supplementing can help restore energy production where it matters most, whether that is in your muscles or your brain. I do want to be clear that much of the clinical evidence is still emerging, and this is a narrative review, not a meta-analysis with pooled statistics. But the direction of the evidence is encouraging, and creatine monohydrate has a remarkably strong safety profile at recommended doses.
What the Research Shows
The review examined evidence across three main groups. For women, the findings suggest that creatine supplementation may help with fatigue-related symptoms tied to the menstrual cycle, particularly during the early follicular and luteal phases when energy demands shift. Since women typically carry lower creatine stores in their muscles compared to men, supplementation may help close that gap and support both physical and cognitive performance.
For vegans and vegetarians, the evidence is particularly relevant. Because creatine is found almost exclusively in animal products like red meat and fish, people on plant-based diets often have reduced creatine stores in both their muscles and brains. Supplementation can improve physical and cognitive performance for this group while supporting their choice to follow a plant-based diet.
The clinical applications are where the review gets especially interesting. Creatine supplementation may help counter muscle wasting in conditions like sarcopenia (age-related muscle loss) and cachexia (disease-related wasting). There is also evidence suggesting potential neuroprotective effects in neurodegenerative diseases such as Parkinson’s and Huntington’s. For people with cardiovascular disease, creatine may help improve exercise capacity. And in chronic fatigue syndrome, it could support energy metabolism in cells that are struggling to produce enough fuel.
Key Patterns Across Studies
One consistent theme throughout this review is the role of creatine in brain energy metabolism. Traumatic brain injury, for example, may benefit from creatine supplementation because creatine helps promote brain energy production and may reduce damage to neurons after injury. This makes biological sense: the brain is one of the most energy-hungry organs in the body, and phosphocreatine plays an important role in keeping brain cells fueled during times of stress.
Another important finding is that creatine monohydrate remains the gold standard among creatine supplements. While many other forms of creatine exist on the market, the review concluded that most available evidence supports creatine monohydrate as the preferred form. It is the most studied, the most consistently effective, and should be considered the go-to option over other variants. The review also emphasized that proper dosing matters. The goal is to maximize benefits while minimizing the risk of potential side effects that could come from taking excessively high doses over long periods.
Gaps in the Evidence
While the direction of the research is promising, there are important limitations to keep in mind. This is a narrative review, meaning the authors summarized the existing literature rather than conducting a systematic analysis with pooled data. Many of the clinical applications, such as neuroprotection in Parkinson’s or improvements in chronic fatigue, are based on early-stage evidence and need larger, more rigorous trials. The specific dosing protocols that work best for women, vegans, or clinical populations are also not yet fully established. More research is needed to determine optimal timing, duration, and amounts for each group.
Practical Takeaways
- If you follow a vegan or vegetarian diet, creatine monohydrate supplementation may help improve both your physical and cognitive performance, since your dietary intake of creatine is likely very low.
- Women experiencing fatigue tied to their menstrual cycle, especially during the early follicular and luteal phases, may benefit from creatine supplementation to help support energy levels.
- When choosing a creatine supplement, stick with creatine monohydrate, as this review found it to be the most well-supported form over other variants on the market.
- Talk to your doctor before starting creatine if you have any clinical conditions, and follow recommended dosing guidelines to avoid potential side effects from excessively high or prolonged intake.

FAQs
Is creatine safe for women to take long-term?
Creatine monohydrate has been studied extensively and is generally considered safe for both men and women at recommended doses. The concern about creatine causing bloating or unwanted weight gain has been largely overstated in the popular media. For women, the potential benefits are notable because they tend to start with lower creatine stores in their muscles. This review highlights that supplementation may specifically help with fatigue during certain phases of the menstrual cycle. As with any supplement, it is best to follow established dosing guidelines and consult with a healthcare provider, especially if you are pregnant or nursing.
How much creatine do vegans and vegetarians need?
The standard recommended approach for creatine monohydrate is a loading phase of about 20 grams per day for five to seven days, followed by a maintenance dose of three to five grams per day. However, some people skip the loading phase and simply take the maintenance dose from the start, which takes a few weeks longer to fully saturate creatine stores. Vegans and vegetarians may respond especially well to supplementation because they start from a lower baseline, getting virtually no dietary creatine from plant-based foods. This means the relative improvement in creatine stores, and the associated performance and cognitive benefits, may be more noticeable for people on plant-based diets than for those who already eat meat regularly.
Can creatine really help with brain injuries or neurodegenerative diseases?
The evidence for creatine’s role in brain health is still in its early stages, but the biological rationale is sound. The brain uses a tremendous amount of energy, and phosphocreatine helps recycle ATP in brain cells just as it does in muscle cells. This review found that creatine supplementation may help promote brain energy metabolism and reduce neuronal damage after traumatic brain injury. For neurodegenerative diseases like Parkinson’s and Huntington’s, early research suggests potential neuroprotective effects. However, these findings have not yet been confirmed by large-scale clinical trials, so creatine should not be considered a treatment for these conditions at this time.
Bottom Line
This narrative review makes a strong case that creatine monohydrate is far more than a sports supplement. Women, vegans, vegetarians, and people dealing with conditions like muscle wasting, neurodegenerative disease, or chronic fatigue may all benefit from supplementation by restoring low creatine stores and improving energy metabolism. Creatine monohydrate remains the preferred form, and proper dosing is key to getting the benefits while avoiding potential downsides. While more research is needed, particularly in clinical populations, the existing evidence paints an encouraging picture of a safe, affordable supplement with applications that reach well beyond the weight room.
