Creatine is everywhere. What does science actually say?
Creatine is everywhere right now. But are the claims around this classic supplement actually based in real science? Or are they just more marketing hype? For decades, creatine has been sold to fitness buffs, as a way to build more muscle, faster. Now it’s being pitched to almost everyone, with influencers, podcasters, and celebrity doctors […]
Creatine, a widely-used supplement, has garnered significant attention lately. However, the claims surrounding its benefits are not always grounded in solid scientific evidence. For years, athletes have turned to creatine as a tool for enhancing muscle growth. Now, it's being marketed to a broader audience with promises of improving cognitive function, mood, combating sleep deprivation, and even reversing Alzheimer's disease.
These wellness claims have led to a substantial increase in sales, with US sales reaching over half a billion dollars in 2025 alone.
So, what is creatine doing within our bodies? Can it genuinely aid in building muscle, or are the dramatic before-and-after images misleading? And when it comes to brain health, is there genuine scientific backing for the claims about memory, mood, and Alzheimer's disease, or is hype outpacing the research?
To answer these questions, we delved into the scientific research on creatine, examining its effects both on muscles and the mind. We also consulted experts in the field.
Exercise scientist Nick Tiller and associate professor Matthew Taylor, from the University of Kansas, provided valuable insights into creatine's impact on Alzheimer's disease. Their studies aimed to shed light on the supplement's potential therapeutic benefits.
However, it's crucial to remember that while creatine has demonstrated benefits in certain contexts, such as improved cognitive performance during sleep deprivation and enhanced body composition in middle-aged adults, the evidence regarding its effects on Alzheimer's disease is still evolving. More research is needed to establish a clear link between creatine supplementation and cognitive health in this specific population.
In conclusion, while creatine's role in promoting muscle growth remains well-established, the claims surrounding its cognitive and neurological benefits require further investigation. As with any supplement, it's essential to approach claims with a critical eye, backed by rigorous scientific research.
