Creatine for Older Adults: What the Research Actually Says
Creatine and Ageing: A Simple, Balanced Guide
I was reading an interesting research paper this week looking at creatine and its potential role in health and physical function in older adults. The paper itself was published last year, which makes it a useful snapshot of where the research currently sits.
Creatine is one of those supplements most people have heard of, but usually associate with bodybuilding or younger athletes. What’s becoming clearer is that it’s being studied far more widely than that – including in ageing populations and everyday health, not just sport.
I get asked a lot of questions by clients and members, and creatine is one that’s come up a few times recently. So rather than relying on headlines or trends, I spent some time reading the research behind it.
There’s a lot of mixed advice online. My aim here isn’t to push anything, but to share what the evidence actually says in a clear, balanced way, so you can make your own informed decision.
What is creatine?
Creatine is a naturally occurring compound found in small amounts in foods like red meat and fish. Our bodies also produce it on their own, mainly in the liver and kidneys.
Around 95% of the creatine in the body is stored in muscle, where it plays a key role in producing quick energy during short bursts of effort – things like standing up from a chair, climbing stairs, lifting shopping, or catching yourself if you lose balance.
As we age, natural creatine stores and muscle mass tend to decline. This is one reason researchers have become interested in whether supplementing creatine could help support strength and function later in life.
What does creatine actually do?
Creatine helps replenish a molecule called ATP, which is the body’s main energy source for short, powerful movements. In practical terms, this means it supports:
Muscle strength and power
Repeated efforts without fatiguing as quickly
Recovery between bouts of effort
In younger populations, creatine is well known for helping people lift heavier weights or perform more repetitions. In older adults, the interest is slightly different.
The focus is less about performance and more about whether creatine can help maintain strength, muscle mass, and physical function that supports everyday life.
What does the research say for older adults?
Recent reviews looking specifically at older populations suggest that creatine supplementation, particularly when combined with resistance or strength training, can lead to modest improvements in:
Muscle strength
Lean muscle mass
Physical performance
Some studies have also explored potential benefits beyond muscle, including effects on bone health and cognitive function, although this area is still developing and results are mixed.
One consistent theme is that creatine seems to work best alongside regular strength-based exercise, rather than as a stand-alone solution.
It’s also worth noting that responses vary between individuals. Not everyone sees the same benefits, which is common with most nutrition and supplementation research.
Is creatine safe?
Creatine is one of the most widely studied supplements available. In healthy adults, it’s generally considered safe when taken at recommended doses.
For older adults, most studies use a daily dose of 3–5 grams per day, without the need for a loading phase.
That said, like most areas of health and nutrition, more research is still needed – particularly long-term studies in non-athletic older populations and across different health conditions.
Anyone with kidney disease, or existing medical conditions, should always speak to a GP or healthcare professional before starting creatine.
Is creatine something everyone over 55 should take?
No – and this is important.
Creatine isn’t a magic fix, and it’s not necessary for everyone. For some people, focusing on regular movement, strength training, adequate protein intake, sleep, and hydration will deliver far bigger returns.
For others, creatine may be a useful addition, particularly if they’re already doing strength-based exercise and looking to support muscle function as they age.
This is where context matters. Supplements should support good habits, not replace them.
Where Jim’s Gym fits into this
At Jim’s Gym, the focus is always on making everyday life easier to move through.
Strength, balance, mobility, and confidence come first. Supplements, if used at all, sit firmly in the background.
If someone chooses to use creatine, it should be alongside sensible, enjoyable exercise that builds real-world strength – the kind that helps with stairs, carrying shopping, getting up from the floor, and staying independent.
That’s exactly what Jim’s Gym sessions are designed to support.
Final thoughts
Creatine is no longer just a conversation for athletes. Research in older adults is growing, and the evidence suggests it may have a role in supporting muscle strength and function when combined with regular exercise.
It’s not essential, it’s not a shortcut, and it won’t replace movement.
But for some people, it might be a useful tool – and like most things, the decision is best made with good information, not hype.
FAQ
What is creatine used for in older adults?
Creatine is being studied for its potential to support muscle strength, lean mass, and physical function in older adults, particularly when combined with strength training.
Is creatine safe for people over 55?
For generally healthy adults, creatine is considered safe at doses of around 3–5 grams per day. Anyone with medical conditions should check with a healthcare professional first.
Does creatine help with mental health or brain function?
Creatine is involved in energy production in the brain, and some early research has explored possible links with cognition and mood. However, the strongest evidence for creatine in older adults relates to physical health, not mental health. Research in this area is still emerging, and more studies are needed before any clear conclusions can be made.
Do I need to exercise if I take creatine?
Yes. Research consistently shows creatine works best alongside resistance or strength-based exercise. On its own, benefits are likely to be limited.
Can creatine help with ageing-related muscle loss?
Some studies suggest creatine may help support muscle mass and strength as part of a wider exercise programme, but results vary and more research is still needed.
Do I need creatine to get stronger at Jim’s Gym?
No. Jim’s Gym focuses on building strength, balance, and confidence through exercise first. Supplements are always optional and secondary.
