Creatine Isn’t Just for Bodybuilders

For years, creatine has been associated with bodybuilding, oversized supplement tubs and people trying to gain as much muscle as possible.

That image is outdated.

Creatine is a naturally occurring compound involved in the body’s rapid energy-production system. Its benefits can be relevant not only to bodybuilders, but also to women, recreational athletes, older adults, vegetarians and people participating in sports that require repeated bursts of effort.

The strongest evidence still relates to physical performance and resistance training. Research into cognition, healthy ageing and other areas is growing, but these emerging findings should not be confused with the well-established performance evidence.

Creatine is not a shortcut or a replacement for training. It is a well-researched tool that may help more people than its bodybuilding reputation suggests.

What does creatine actually do?

Your body uses adenosine triphosphate, or ATP, as an immediately available source of cellular energy.

During short and intense activity—such as lifting a weight, accelerating on a bicycle, sprinting for a ball or climbing a steep hill—ATP is used rapidly. Stored phosphocreatine helps regenerate ATP, allowing your muscles to continue producing high levels of effort for slightly longer or recover more effectively between repeated efforts.

Creatine supplementation increases the amount of creatine and phosphocreatine available in muscle. It does not create energy out of nowhere and does not make you stronger without training. Instead, it may help you perform more productive work over time.

In the European Union, the authorised health claim states that creatine increases physical performance in successive bursts of short-term, high-intensity exercise. The beneficial effect is obtained with a daily intake of 3 grams of creatine and applies to adults performing high-intensity exercise. European Commission Regulation (EU) No 432/2012

That definition covers far more than bodybuilding.

Creatine is for people who train for strength

You do not need to compete or look like a bodybuilder to benefit from being stronger.

Strength supports everyday movement, athletic performance and the ability to continue doing physically demanding activities. Resistance training can include traditional weightlifting, group strength classes, functional training, bodyweight exercise or a structured home programme.

A 2024 systematic review and meta-analysis concluded that creatine combined with resistance training improved both upper- and lower-body strength in adults under 50 compared with resistance training alone. Wang et al., 2024 – PubMed

Research using direct measurements of muscle size also suggests a small additional benefit for muscle growth when creatine is combined with resistance training. The effect is real but not magical: training remains the primary stimulus. Burke et al., 2023 – PubMed

Creatine may help you complete another repetition, maintain performance across several sets or tolerate more useful training volume. Repeated consistently, those small improvements can matter.

Creatine is for women too

Creatine is often marketed primarily to men, but its basic biological role is not male-specific.

Women use the same phosphocreatine energy system and can have the same performance-related reasons to supplement. Creatine does not contain testosterone, is not an anabolic steroid and does not automatically make women bulky.

Building substantial muscle requires consistent resistance training, progressive overload, adequate nutrition and time. Taking a normal daily dose of creatine by itself will not suddenly transform a woman’s physique.

Research into creatine specifically across the female lifespan is developing. Reviews have explored its potential relevance to exercise, ageing and cognition, while also acknowledging that women remain underrepresented in many supplementation studies. Smith-Ryan et al., 2021 – PubMed

The strongest reason for an active woman to consider creatine remains straightforward: supporting repeated high-intensity performance and getting more from well-designed resistance training.

Claims involving pregnancy, menopause, mood or other clinical outcomes require considerably more caution. Promising early evidence is not the same as a universal recommendation, particularly during pregnancy or while breastfeeding.

Creatine may be relevant as we age

Strength and muscle function become increasingly important with age. Losing the ability to produce force can affect balance, mobility and independence—not only appearance.

Creatine cannot prevent ageing, and it cannot replace resistance exercise, sufficient protein intake or an active lifestyle. However, evidence suggests that it may strengthen the adaptations produced by resistance training in older adults.

A meta-analysis found that creatine supplementation during resistance training increased lean tissue mass and improved upper- and lower-body strength in older adults compared with training alone. Chilibeck et al., 2017 – PubMed

Another meta-analysis concluded that creatine combined with resistance training can augment gains in lean tissue and strength in ageing adults, although results vary between studies and protocols. Forbes et al., 2021 – PubMed

The practical message is not that every older person should immediately take creatine. It is that creatine research is relevant to maintaining physical function—not only to building large muscles.

Older adults, particularly those with medical conditions or using multiple medications, should discuss supplementation with an appropriate healthcare professional.

Creatine can support recreational athletes

You do not have to train professionally to perform repeated high-intensity efforts.

Many everyday sports include:

• Short sprints
• Accelerations
• Jumps
• Direction changes
• Steep climbs
• Powerful strokes
• Repeated high-intensity intervals

This can include football, basketball, padel, tennis, cycling, swimming, CrossFit-style training and interval workouts.

A systematic review and meta-analysis found that short-term creatine supplementation can improve aspects of repeated-sprint performance, although the size of the benefit and individual response vary. Glaister et al., 2022 – PubMed

Creatine is most relevant when a sport repeatedly demands high power. It is less likely to transform performance in steady, low-intensity activity.

For the recreational athlete, the value is not necessarily a dramatic one-time improvement. It may be the ability to maintain quality across a demanding session and gradually accumulate better training.

What about runners, cyclists and endurance athletes?

Creatine is not a traditional endurance supplement, and the evidence does not show a clear overall improvement in continuous endurance performance.

A 2023 systematic review and meta-analysis found no statistically significant overall improvement in endurance performance among trained participants using creatine monohydrate. Fernández-Landa et al., 2023 – PubMed

This does not make creatine irrelevant to every runner or cyclist.

Endurance training frequently includes:

• Hill repetitions
• Interval sessions
• Strength training
• Sprint finishes
• Repeated accelerations
• Rehabilitation work

Creatine may support these high-intensity components even if it does not directly improve a long, steady endurance effort.

There is also a trade-off. Creatine can produce a small increase in body mass, particularly during the early stages of supplementation. For athletes in sports where carrying additional weight affects performance, that change should be considered rather than ignored.

A marathon runner and a track sprinter do not have the same reason to use creatine. The decision should reflect the demands of the sport and the individual training programme.

Vegetarians and vegans may respond differently

Creatine occurs naturally in animal-derived foods, particularly meat and fish. Plant foods contain very little creatine, so vegetarians and vegans typically consume less through their diets.

A review comparing vegetarians with omnivores found that vegetarians generally had lower baseline creatine stores and often experienced larger increases in creatine levels after supplementation. Improvements in physical performance were not consistently greater in every study, but some measures of lean tissue and cognition appeared to respond favourably. Kaviani et al., 2020 – PubMed

This does not mean that everyone following a plant-based diet is deficient. The body can synthesise creatine from amino acids.

It does mean that dietary patterns can influence starting creatine stores—and potentially the response to supplementation.

Creatine monohydrate itself is commonly produced synthetically rather than extracted from animal tissue, but vegans should still check the complete formula and capsule or packaging information.

Is creatine useful for the brain?

The brain also requires substantial energy and contains its own creatine-phosphocreatine system. This has led researchers to investigate whether supplementation may support cognitive performance.

A 2024 systematic review and meta-analysis found evidence of potential improvements in some cognitive measures, including memory and processing-related outcomes. However, the certainty and consistency of the evidence differed across cognitive domains. Xu et al., 2024 – PubMed

A separate meta-analysis found that creatine supplementation improved some measures of memory, with potentially larger effects in older adults. Prokopidis et al., 2023 – PubMed

Research also suggests that creatine may become more relevant when the brain is under unusually high energy demand. In a controlled 2024 study, a high single dose improved aspects of cognitive performance during sleep deprivation. However, this specific protocol should not be converted into a general daily-dose recommendation. Gordji-Nejad et al., 2024 – PubMed

The evidence for cognitive benefits is promising, not definitive. Creatine should not be marketed as a treatment for fatigue, poor sleep, memory problems or mental-health conditions.

For now, cognition is a developing area of research. Physical performance remains the more firmly established reason to use creatine.

Creatine is not only for gaining size

Some people avoid creatine because they assume its only purpose is increasing body weight.

Creatine may cause a modest early increase in weight because changes in muscle creatine stores can affect body water. That is not the same as gaining body fat.

Over a longer period, creatine combined with resistance training may support greater gains in lean tissue. However, increased muscle size is not the only possible outcome of better training.

People may use resistance training to improve:

• Strength
• Power
• Movement capacity
• Sporting performance
• Confidence under physical load
• Long-term physical function

You can value these outcomes without wanting to become a bodybuilder.

Who is most likely to benefit?

Creatine may be particularly relevant if you:

• Perform resistance training
• Participate in repeated-sprint or high-intensity sports
• Want to improve strength or power
• Include intense intervals in your training
• Follow a vegetarian or vegan diet
• Are an older adult using resistance exercise to maintain strength and function

Creatine may be less relevant if your activity is almost entirely low intensity, you are unwilling to train consistently or a small increase in body mass would work against an immediate competitive goal.

It is a useful tool—not a compulsory part of being healthy.

How should you take creatine?

For most healthy adults, the simplest approach is:

• Choose creatine monohydrate
• Take 3–5 grams per day
• Take it consistently, including on rest days
• Use it at whatever time best fits your routine
• Skip the loading phase unless faster saturation is important

A loading phase usually involves approximately 20 grams per day, divided into several smaller servings for five to seven days, followed by 3–5 grams daily. Loading is optional and may cause a more noticeable initial increase in body weight or digestive discomfort.

Creatine does not need to be cycled. It also does not need to be consumed immediately before a workout to be effective.

Is creatine safe?

Creatine monohydrate is one of the most extensively researched sports supplements and is generally well tolerated by healthy adults when used appropriately.

A comprehensive evidence review found no convincing support for common claims that recommended creatine use causes dehydration, muscle cramping or kidney damage in healthy people. Antonio et al., 2021 – Journal of the International Society of Sports Nutrition

Creatine supplementation can influence measured blood creatinine. This does not automatically mean impaired kidney function, but it may affect the interpretation of laboratory results. Inform your healthcare professional that you take creatine before relevant blood tests.

People with kidney or liver disease, those using relevant medication, and anyone who is pregnant, breastfeeding or under 18 should consult a qualified healthcare professional before using creatine.

The bottom line

Creatine earned its reputation in the weight room, but it does not belong exclusively to bodybuilding culture.

Its most established role is supporting performance during repeated bursts of short-term, high-intensity exercise. That can matter to women, recreational athletes, older adults, plant-based eaters and anyone using structured training to become stronger.

The research outside sport is expanding, particularly in cognition and healthy ageing. Those findings are worth following—but they should be communicated with more care than the established performance benefits.

Creatine will not replace training, sleep, nutrition or consistency.

It may help you get more from them.

Frequently asked questions

Is creatine only useful if you lift weights?

No. Creatine is most relevant to activities involving repeated high-intensity efforts. Resistance training is one example, but sprinting and many team or racket sports also include this type of effort.

Can beginners take creatine?

Healthy adult beginners can use creatine, but establishing a consistent training routine matters more than adding a supplement. Creatine cannot compensate for an ineffective programme.

Can women take creatine?

Yes. Creatine’s energy-related role is not male-specific, and women do not automatically become bulky from using it. Pregnancy and breastfeeding require separate professional medical guidance.

Is creatine useful after 50?

Creatine combined with resistance training may support gains in strength and lean tissue in older adults. It should complement—not replace—exercise, adequate nutrition and medical care.

Can vegetarians and vegans take creatine?

Yes. Because plant-based diets provide little dietary creatine, vegetarians and vegans may begin with lower creatine stores. Check that the complete supplement formula meets your dietary requirements.

Does creatine help endurance athletes?

It does not appear to improve continuous endurance performance overall. It may still support strength training, intervals, sprints and other high-intensity elements of an endurance programme.

Does creatine give you energy like caffeine?

No. Creatine is not a stimulant and does not usually create an immediate feeling of alertness. It supports the body’s rapid cellular energy system over time.
