Creatine is one of the world’s most researched supplements, with studies suggesting benefits that extend far beyond the gym. So why isn’t it routinely recommended by doctors? The answer has less to do with creatine itself than with how medical advice evolves

For decades, creatine has been synonymous with bodybuilding. Mention it in the pub and someone will inevitably picture a protein shaker, bulging biceps and the weights room. Yet today’s research paints a much broader picture. Scientists are investigating creatine’s potential role in healthy ageing, brain function, muscle preservation, recovery from injury and even mood.
Which raises an obvious question. If the evidence is becoming so compelling, why has your GP probably never suggested taking it?
The answer isn’t that doctors are ignoring the science. Nor is it because creatine has been “suppressed” or overlooked. It’s because medicine and sports nutrition work in very different ways – and the bar for changing clinical advice is incredibly high.
Creatine wasn’t developed for general health
Creatine’s story began in sport. Most early studies focused on athletes, examining whether it improved sprint performance, strength and muscle growth. Those benefits are now well established, which is why organisations such as the International Society of Sports Nutrition consider creatine monohydrate both effective and safe for healthy adults.
But improving a 100-metre sprint isn’t something most GPs are asked about during appointments.
Doctors are trained to diagnose illness, prescribe treatments and prevent disease. Historically, creatine simply wasn’t relevant to most consultations.
The research has changed
Over the past decade, scientists have begun asking different questions.
Instead of studying young male athletes, they’re increasingly investigating older adults, women, vegetarians, people recovering from illness and those at risk of age-related muscle loss.
Researchers are exploring whether creatine might help:
- preserve muscle during ageing
- improve the benefits of resistance training
- support bone health indirectly through stronger muscles
- reduce fatigue during periods of sleep deprivation
- enhance certain aspects of memory and thinking
- support recovery from injury.
Some of these areas already have encouraging evidence. Others remain promising but inconclusive. That’s exactly how science progresses.
Medical advice moves more slowly than headlines
A single positive study rarely changes medical practice.
Before doctors begin routinely recommending anything, researchers want multiple high-quality trials, systematic reviews and evidence that benefits outweigh any potential risks across different populations.
Clinical guidelines can take years to update, sometimes decades. That’s not a flaw- it’s one of the reasons modern medicine is trusted.
By the time advice reaches your GP’s consulting room, the evidence has usually been scrutinised from every possible angle.
Doctors aren’t nutrition specialists
Another reason creatine doesn’t come up often is simple: time.
The average GP appointment lasts only a few minutes and is usually focused on the problem that brought you through the door.
Unless you ask specifically about exercise, supplements or healthy ageing, there’s little opportunity to discuss them.
Nutrition also receives relatively little attention in many medical training programmes compared with diagnosing disease or prescribing medication. For more specialised advice, patients are often referred to registered dietitians or other healthcare professionals.
Creatine still isn’t right for everyone
Despite its impressive safety record, creatine isn’t something every doctor will recommend automatically.
People with existing kidney disease or other significant medical conditions should speak to their healthcare team before taking any supplement. There’s also less evidence for certain groups, such as pregnant or breastfeeding women.
Good doctors tend to individualise advice rather than recommend supplements across the board.
So should everyone be taking it?
Not necessarily. If you’re already strength training, looking to preserve muscle as you age or following a vegetarian or vegan diet—which tends to provide less creatine naturally – you may be more likely to benefit than someone who is inactive and has no interest in exercise.
But creatine isn’t a substitute for the fundamentals.
Regular resistance training, sufficient protein, quality sleep and a balanced diet remain far more important than any supplement.
Think of creatine as something that can enhance those habits, not replace them.
The bottom line
Your GP probably hasn’t mentioned creatine because it’s still crossing the bridge from sports nutrition into mainstream healthcare.
The evidence for improving strength and exercise performance is already robust, while research into healthy ageing, brain function and other medical applications continues to grow. Whether creatine eventually becomes as commonplace as vitamin D or omega-3 advice remains to be seen, but one thing is clear: its reputation has moved well beyond the gym floor.
The conversation around creatine is changing. Medicine is simply taking the careful, evidence-based route that it always has.
