For years, creatine has been surrounded by myths. For some, it’s “a dangerous substance that harms the kidneys”; for others, a supplement only for bodybuilders. However, science has made it clear: creatine is safe, effective, and could be much more than just a performance enhancer.
Creatine is a natural substance found in the human body, primarily in the muscles. It’s also obtained from foods like red meat and fish, as well as in supplement form. Its main function is to help regenerate ATP (adenosine triphosphate), the energy molecule that muscles use during intense physical effort.
That’s why it has become a key ally for improving strength, high-intensity performance, and muscle recovery. But its benefits don’t stop there.
Myth 1: “Creatine damages the kidneys”
This is one of the most widespread myths—and also one of the most debunked by research. Dozens of studies have shown that creatine use in healthy individuals does not cause kidney damage. Increases in creatinine levels (a kidney marker) sometimes seen in users do not indicate dysfunction but are instead a natural byproduct of muscle metabolism.
Myth 2: “It just makes you retain water”
It’s true that creatine can increase intracellular water retention, especially in the first weeks of use. But far from being negative, this can improve muscle hydration and promote an anabolic (muscle-building) environment. Also, the weight gain that some people experience is mostly lean mass—not fat.
Myth 3: “It’s only for athletes”
This is a big misconception. Recent research has shown that creatine also offers cognitive benefits. It can help improve memory, brain function under fatigue, and mood—especially in older adults or those on low-meat diets. Its therapeutic potential is even being studied in neurological diseases like Parkinson’s and depression.
Scientifically proven benefits of creatine:
- Increased strength and muscle mass
- Enhanced performance in high-intensity workouts
- Faster post-exercise recovery
- Protection against cognitive decline
- Support for healthy aging and bone health
- Improved brain function in vegan or vegetarian diets
Who can benefit from creatine use?
• Athletes and active individuals seeking better performance
• Older adults with muscle loss
• Students or professionals with high cognitive demand
• People on vegetarian or vegan diets (due to low natural intake)
• Patients with certain neuromuscular conditions (under medical supervision)
Creatine is not a “magic potion,” but it is a supplement with real, proven benefits supported by over 1,000 scientific studies. Its use is not only safe in healthy individuals—it may actually represent a boost to both physical and mental well-being at any age. Debunking creatine myths opens the door to a powerful tool for those looking to care for their health from the inside out.
