Creatine for Brain Health: Benefits, How to Use and More

Creatine is probably best known for its connection to strength training, muscle performance and exercise recovery. However, this compound also plays an important role in energy, which has led researchers to examine the potential benefits of creatine for brain health.

Creatine is a nitrogen-containing compound made by the body from three amino acids: arginine, glycine and methionine. You can also obtain creatine through the diet, primarily from foods with creatine, such as meat and fish.

Once in the body, creatine is converted to phosphocreatine, which helps produce adenosine triphosphate (ATP). ATP serves as an energy source for cells throughout the body.

This is particularly relevant to the brain. Although the brain accounts for only about 2 percent of total body weight, it uses approximately 20 percent of the body’s energy at rest.

Creatine can act as a readily available reserve that helps replenish ATP when energy requirements increase, including during demanding mental tasks, fatigue and aging. Brain cells and neurons require a consistent supply of energy to support processes such as neurotransmitter release, synaptic activity and the maintenance of ion gradients.

Research on creatine supplementation suggests that its role may extend beyond muscles to supporting brain and cognitive health.

Benefits of creatine for brain health

Research into creatine for brain health continues to evolve. While findings are promising in several areas, more research is needed to fully understand its cognitive effects.

Here are some of the primary ways creatine supplementation may support brain function and cognitive performance.

1. May support processing speed, attention and mental focus

The potential cognitive benefits of creatine aren’t limited to memory. Research suggests creatine may also support information-processing speed, attention time, mental focus and cognitive resilience.

A systematic review and meta-analysis published in Frontiers in Nutrition found a significant effect of creatine supplementation on processing speed time. However, the researchers characterized some areas of the available evidence as being of low certainty.

These findings suggest creatine may have a role in supporting cognitive resilience in addition to cognitive function.

2. Supports memory and learning

Creatine supplementation has been studied for its potential to support working memory, recall and reasoning, particularly when baseline creatine levels are lower or during periods of stress.

The Frontiers in Nutrition systematic review and meta-analysis mentioned above found beneficial effects associated with creatine monohydrate supplementation in areas that included memory, attention time and information-processing speed.

Some research also indicated that vegetarians may experience greater improvements in memory following creatine supplementation. Because meat and fish are major dietary sources of creatine, vegetarians may have lower baseline creatine stores.

3. May aid brain health during stressful conditions

Periods of stress can place additional demands on the brain, and research has examined whether creatine can help support cognitive performance under these circumstances.

A 2024 study published in Scientific Reports found that creatine supplementation improved processing speed.

Research published in Experimental Gerontology also found that supplementing with creatine may help maintain reaction time and decision-making ability in high-pressure or stressful situations.

4. Helps support brain health

Creatine is also being investigated for its potential role in supporting brain health during the normal aging process.

The Frontiers in Nutrition meta-analysis referenced above indicated cognitive benefits associated with creatine among adults ages 18 to 60 and among females, providing another potential reason for women to use creatine.

Evidence involving adults older than 60 remains more limited, however, highlighting the need for additional research.

How to use creatine for brain health

If you’re considering creatine for brain health, the form, amount, consistency and duration of supplementation are all factors to consider. Individual needs can vary, so consult a healthcare provider before starting a new supplement routine.

Choose an appropriate form

Creatine monohydrate is the most extensively studied form of creatine for both muscle-related and cognitive outcomes.

When selecting a creatine supplement, look for a quality product that provides an effective amount of creatine. Some formulas also pair creatine with other nutrients.

Ancient Nutrition’s Creatine + Collagen products are high-quality options to consider:

• Creatine + Collagen has been shown to help support brain health, verbal working memory, mental performance when under time constraints and more.
• Creatine + Collagen + Electrolytes has been shown to offer those same brain-supporting benefits while also providing electrolytes to support hydration balance and muscle recovery.

Consider amounts and timing

A typical maintenance amount used in cognitive research is three to five grams of creatine monohydrate per day.

Some studies begin with a loading phase of approximately 20 grams per day for five to seven days, divided into multiple doses, before transitioning to a maintenance amount. A loading phase can help saturate tissue stores more quickly, but it isn’t required.

As for the best time to take creatine, creatine can generally be taken at any time of day. Taking it consistently at roughly the same time each day may be helpful for establishing a routine.

Taking creatine with a meal containing carbohydrates and protein may help improve uptake. Research also suggests that taking creatine after a workout may be slightly more beneficial for optimal results. Overall, however, consistency appears to be more important than timing.

Give it enough time

Some brain-related benefits may become apparent after about six weeks of consistent supplementation, although many studies have examined longer periods of use.

For ongoing support of brain health, including cognitive resilience and normal aging, a consistent maintenance amount may be prudent.

Keep safety and individual considerations in mind

Creatine monohydrate is generally considered safe among healthy adults when consumed at studied amounts. One possible effect is water retention because creatine draws water into the muscles.

People with pre-existing kidney or liver conditions, pregnant or breastfeeding women, and children should speak with a healthcare provider before using creatine for brain health.

Creatine supplementation also isn’t a replacement for foundational habits that support brain health, including proper nutrition, quality sleep, regular physical activity and stress management.

Frequently asked questions

Is creatine good for brain health?

Research suggests creatine may support several aspects of brain and cognitive health. Studies have examined its potential effects on memory, attention, processing speed, learning, mental focus and cognitive performance under stressful conditions.

Creatine also helps support ATP, which is especially relevant because the brain requires a substantial and consistent supply of energy. However, research into many of creatine’s cognitive benefits is still emerging, and additional studies are needed.

Who may benefit from taking creatine for brain health?

Creatine may be particularly useful for people experiencing high levels of cognitive demand, such as those performing intensive mental work. Vegetarians and vegans may also be candidates because their dietary creatine intake may be lower.

Older adults interested in maintaining brain and cognitive health may consider creatine as well, although research involving adults older than 60 remains more limited.

Creatine may also appeal to people looking to support memory, attention, processing speed and mental acuity, though individual results can vary.

How much creatine should you take for brain health?

A maintenance amount of approximately five grams of creatine monohydrate per day is commonly used for brain health purposes. Some research uses an initial loading period of about 20 grams per day, divided into four to five doses for five to seven days, followed by a lower maintenance amount. Always follow the directions on the supplement label, and consult your healthcare professional before beginning any new dietary, lifestyle or supplementation regimen.

Do you need to load creatine for brain health?

No. A creatine loading phase is optional.

Loading with approximately 20 grams per day divided across several doses for five to seven days can saturate creatine stores more quickly. For brain health purposes, however, consistent daily supplementation over time may be more important than completing a loading phase.

How long does creatine take to support brain health?

Some people may notice improvements in mental clarity or memory after approximately six weeks of consistent creatine use. Many studies, however, have used supplementation periods longer than six weeks. For example, a meta-analysis involving 16 randomized, controlled trials found benefits across different supplementation durations, but additional research is needed to establish the optimal amount of time required to produce cognitive effects.

What type of creatine is best for brain health?

Creatine monohydrate is the most studied form for both cognitive and muscle-related outcomes. When choosing a supplement, look for a quality creatine product, follow its label directions and consider the amount of creatine provided per serving.

When is the best time to take creatine for brain health?

Creatine can be taken at any time of day. Taking it consistently each day appears to be more important than choosing a particular time.

It may be taken with a meal containing protein and carbohydrates, which may help with uptake. Some research also suggests taking creatine after exercise may be slightly more beneficial for optimal results.
