Creatine Is Not Just for the Gym Anymore — Here's the Full List of People Who Are Now Taking It
For a long time, creatine had one image: big guy at the gym, protein shaker in hand. That image is well and truly outdated. Scientists, doctors, and everyday people are rethinking who actually benefits from this molecule — and the list is surprisingly broad.
So What Exactly Is Creatine?
Creatine is a naturally occurring compound your body makes from amino acids, primarily stored in your muscles. It plays a central role in producing quick bursts of energy — the kind your cells need during intense activity or mental effort. You also get small amounts from eating meat and fish.
The key insight that's changed everything: creatine isn't just an energy booster for athletic performance. It helps recycle cellular energy in tissues with high energy demands — including your brain.
Athletes and Gym-Goers (The Originals)
Yes, this group still belongs on the list. Creatine remains one of the most studied and well-supported supplements in sports science. Resistance training, sprint-based sports, and high-intensity interval work all draw heavily on the energy systems creatine supports.
Some research has confirmed its effectiveness for strength and power output — with a strong safety record over decades of research.
Older Adults — Perhaps the Most Important Group
Here's where things get really interesting. From midlife onward, muscle mass and strength naturally start to decline — a process called sarcopenia. Over time, reduced muscle strength can affect balance, independence, and quality of life.
Creatine, combined with resistance exercise, has been linked to gains in muscle strength and lean mass in older adults. Some research suggests that older adults supplementing with creatine while doing resistance training showed greater improvements in muscle strength compared to exercise alone.
In Singapore, where the older adult population is growing fast, this is particularly relevant. Staying strong matters not just for gym performance but for everyday life — getting up from a hawker centre stool, carrying groceries, staying independent.
Vegetarians and Vegans
Your body produces creatine naturally, but dietary intake — mainly from red meat and fish — also contributes to your total stores. People following plant-based diets may have lower baseline creatine levels in their muscles.
Some research suggests that vegetarians may respond more noticeably to creatine supplementation, particularly in memory tasks, possibly because they're starting from a lower baseline. Research here is still limited, so it's too early to say how large any benefit might be.
Students and Knowledge Workers
The brain uses a significant amount of energy — and creatine plays a role in fuelling it. This has sparked genuine scientific interest in creatine's effects on cognition, memory, and mental fatigue.
Some small trials, mostly in vegetarians and older adults, have reported improvements in memory and reasoning tasks among people who supplemented with creatine. However, results are mixed, and research in healthy, well-rested young adults eating a balanced diet remains limited.
For Singapore's kiasu culture of students cramming for exams or professionals pushing through long work hours in air-conditioned offices, the idea of supporting brain energy is appealing — though the evidence is still developing.
Sleep-Deprived Individuals
This one surprises people. When you're sleep-deprived, your brain's energy reserves take a hit. Preliminary research suggests creatine may help buffer some of the cognitive decline associated with poor sleep — particularly in short-term memory and more complex mental tasks. More research is needed.
People Managing Certain Health Conditions
Emerging research is exploring creatine's role in conditions involving muscle wasting, neurological health, and metabolic function. Studies have looked at its potential relevance in settings ranging from heart failure recovery to neurodegenerative conditions — though this remains an active area of research rather than established clinical practice.
It's also being explored as a supportive nutrient in managing type 2 diabetes, a condition that is common worldwide. Some small studies suggest it may support glucose metabolism when combined with exercise, but this is not yet confirmed — and it should never replace medical treatment.
Women — Widely Underrepresented, Highly Relevant
Creatine research has historically focused on men, but that's changing. Women appear to have naturally lower creatine stores than men, which has led researchers to ask whether supplementation could be especially relevant for them.
Researchers are now looking at creatine's potential role during pregnancy, postpartum recovery, perimenopause, and beyond — especially for supporting muscle and cognitive function during hormonal transitions. Human research in pregnancy and perimenopause is still limited, so this is an area to watch rather than a settled answer.
What to Keep in Mind
Creatine is generally considered safe and well-tolerated by healthy adults. It is one of the most researched supplements in existence. However, people with kidney conditions, those who are pregnant, or those on certain medications should speak with a doctor before starting any supplement.
The form most studied is creatine monohydrate — simple, affordable, and backed by the strongest body of evidence. Staying well hydrated is always a good habit, and research has not shown that creatine itself causes dehydration.
