Creatine Monohydrate for Older Adults: A Simple Summary of the Research
This article is a simple summary of the research paper called Creatine Monohydrate Supplementation for Older Adults and Clinical Populations. The paper was published in the Journal of the International Society of Sports Nutrition in 2025. You can also view the published article through its DOI link here.
The article looks at whether creatine monohydrate may help older adults and people with certain health conditions. Creatine is already well known in sports nutrition, but this review explains that it may also have a useful role in healthy ageing, muscle strength, bone health, brain function and some clinical populations.
What Is Creatine?
Creatine is a natural compound found in the body. It is also found in foods such as meat and seafood. The body stores most creatine in muscle, where it helps produce quick energy. This energy is especially important when the body needs to work harder, such as during exercise, lifting, walking upstairs, recovering from illness, or using the brain for demanding tasks.
Creatine works closely with ATP, which is often described as the body’s energy currency. When cells need energy quickly, creatine helps recycle ATP so the cell can keep working. This is why creatine is important for muscles, but also why researchers are interested in its possible effects on the brain, bones and ageing.
Why Creatine Matters for Older Adults
As people get older, they commonly lose muscle mass, strength, bone quality, physical function and sometimes cognitive ability. This does not happen to everyone at the same speed, but it is a common part of ageing. Loss of muscle and strength can make everyday life harder. It can affect walking, climbing stairs, getting out of a chair, carrying shopping, balance and independence.
The article explains that sarcopenia is the age-related loss of muscle strength, muscle size and function. Sarcopenia increases the risk of falls, fractures and disability. Because of this, anything that can safely support muscle strength and function in older adults is important for healthy ageing.
The Main Finding: Creatine Works Best With Exercise
One of the strongest messages from the article is that creatine monohydrate seems to be most useful when it is combined with resistance training. Resistance training means exercises that make the muscles work against force. This could include weights, machines, resistance bands, bodyweight exercises, or supervised strength training.
The review says that creatine monohydrate, especially at doses of around 3 grams or more per day, combined with resistance training, can help improve lean body mass, muscle size, muscle density, strength and some measures of physical function in older adults.
In simple words, creatine is not a magic powder that replaces exercise. It appears to work best as a partner to strength training. Exercise gives the body the signal to build or maintain muscle, and creatine may help the body respond better to that signal.
Muscle Strength and Daily Function
The article reports that creatine combined with resistance training has been linked with improvements in upper-body strength, such as chest press or bench press strength. This matters because upper-body strength is useful for normal daily tasks, including pushing, lifting and carrying.
The results for lower-body strength are more mixed. Some studies show benefits, while others do not show clear improvements compared with exercise alone. This may be because lower-body muscle loss can be more difficult to improve in older adults, or because different studies used different doses and training plans.
Creatine may also help with functional ability. Functional ability means practical movements that matter in real life, such as standing up from a chair, walking, and staying mobile. Some research suggests creatine with training may improve sit-to-stand performance, which is a useful measure of independence in older adults.
Bone Health, Falls and Frailty
The article also discusses bone health. Bone health matters because older adults are at higher risk of osteoporosis, fractures and loss of independence after falls.
The research suggests creatine combined with resistance training may have some positive effects on bone area, bone thickness and bone strength. However, the evidence is not as strong as it is for muscle. Some findings are promising, but not all studies agree, and some changes may be too small to clearly reduce fracture risk.
The article also explains that creatine may improve some factors related to fall risk, such as muscle quality, walking speed and sit-to-stand ability. However, there is not yet strong proof that creatine reduces the actual number of falls. More long-term studies with larger groups of older adults are needed.
For frailty, the evidence is also mixed. Frailty includes weakness, slow walking speed, exhaustion, unplanned weight loss and low physical activity. The article suggests resistance training itself is very powerful for frail adults, but creatine may not always add much extra benefit in this group.
Metabolic Health and Type 2 Diabetes
The article discusses possible benefits for metabolic health. Metabolic health includes how the body handles blood sugar, insulin, fat and energy. This is important because older adults are more likely to develop conditions such as type 2 diabetes, obesity and problems with blood fats.
Some evidence suggests creatine may support glucose metabolism, especially when combined with exercise. One small study in people with type 2 diabetes found that creatine with exercise helped reduce blood glucose and HbA1c, which is a marker of longer-term blood sugar control.
This does not mean creatine is a treatment for diabetes by itself. The better message is that creatine may support exercise-related improvements in glucose control. People with diabetes should always speak to a healthcare professional before adding supplements.
Brain Health and Memory
The article also looks at the ageing brain. The brain uses a lot of energy, and creatine is involved in energy support. This is why researchers are studying whether creatine might help memory, thinking and brain health, especially in older adults or people under mental stress.
Some studies suggest creatine may improve memory in older adults. There is also early research looking at creatine in Alzheimer’s disease. One small study found that creatine increased brain creatine levels and improved some measures of cognition and memory in older adults with Alzheimer’s disease.
However, the article is careful. The evidence for brain benefits is still developing. Some studies show positive results, while others do not. The brain does not absorb creatine as easily as muscle, so dose, duration, age and health condition may all matter.
Clinical Populations
The review also discusses people with certain clinical conditions, including neuromuscular disorders and metabolic conditions. The results vary depending on the condition. For example, the evidence appears more supportive in some muscular dystrophy groups, but not supportive for conditions such as ALS or some mitochondrial disorders.
This is important because it shows that creatine should not be promoted as a cure-all. It may help some groups, but it may not help others. The condition, dose, exercise programme and individual health status all matter.
Is Creatine Safe?
The article says creatine monohydrate is generally considered safe, and the safety of creatine has been widely studied. In older adults, studies have not shown major safety problems when creatine is used with exercise or in the limited creatine-only trials available.
However, the article also says more older-adult-specific safety research is needed. This is because older adults may take several medications or have kidney, liver or other health conditions. Creatine can raise creatinine levels in blood tests, but this does not always mean kidney damage. Even so, people with kidney disease, liver disease or complex medication lists should speak to a healthcare professional before using creatine.
Simple Takeaway
The simple takeaway is that creatine monohydrate is one of the more promising supplements for healthy ageing, especially when combined with resistance training. It may help older adults support muscle mass, strength, physical function and possibly some aspects of bone and brain health.
However, creatine is not a replacement for exercise, good nutrition, sleep, medical care or a healthy lifestyle. The strongest evidence is for creatine plus resistance training, not creatine alone. The research is promising, but some areas still need more evidence, especially falls, frailty, long-term bone outcomes, brain health and clinical conditions.
Final Thoughts
For a wellness and longevity audience, this article is useful because it shows that creatine is not just a bodybuilding supplement. It may also be relevant to ageing, independence, strength, energy and healthspan.
The safest message is this: creatine monohydrate may be a useful supplement for some older adults, particularly alongside strength training, but it should be used sensibly. People with medical conditions or those taking medication should get professional advice before starting.
