Few supplements attract as much myth as creatine. It's also one of the most studied substances in all of sports nutrition, so we can actually check the stories against the evidence. Here are the big ones.

Myth: “Creatine is a steroid”
Fact: It isn't. Creatine is a naturally occurring compound found in your body and in foods like meat and fish. It has nothing to do with anabolic steroids or hormones — it simply helps replenish short-burst energy in muscle.
Myth: “Creatine damages your kidneys”
Fact: In healthy people, long-term studies haven't shown harm to kidney function at normal doses. It can slightly raise a blood marker called creatinine (a by-product), which can look alarming on a test but reflects the creatine itself, not damage. If you have existing kidney issues, talk to your doctor first — sensible advice for any supplement.
Myth: “It's just water weight”
Fact: Creatine does draw a little water into your muscle cells, which is part of how it works — not bloating under the skin. Beyond that early shift, its recognised benefit is on physical performance in short, high-intensity efforts, which is exactly what the authorised claim reflects.
Myth: “Creatine is only for bodybuilders”
Fact: It's relevant to anyone doing repeated short, intense efforts — sprinting, team sports, HIIT, resistance training. There's even an authorised claim that daily creatine can enhance the effect of resistance training on muscle strength in adults over 55, making it of interest well beyond the gym-bro stereotype.
Myth: “Women shouldn't take it”
Fact: There's nothing male-specific about creatine. Women use it for the same performance reasons, and it won't cause “bulking” on its own — muscle size depends on training and diet, not creatine alone.
Myth: “You must load, and cycle on and off”
Fact: Loading only speeds up saturation — it's optional. And there's no need to “cycle” creatine; consistent daily use is the norm. See our how to take creatine guide for the simple routine.
