Few supplements attract as many myths as creatine — that it wrecks your kidneys, that it's a steroid, that it causes hair loss. This guide tackles the most common creatine myths honestly and factually, so you can decide with clear information rather than scare stories.
For transparency: creatine carries no authorised health claims in the UK, and this article makes none. Addressing safety myths is about giving accurate, balanced information — not implying creatine produces any benefit. As always, anyone with a health condition should check with their GP.
Myth 1: "Creatine damages your kidneys"
This is the most persistent myth, and it largely stems from a misunderstanding. Creatine raises blood creatinine — a marker doctors use to estimate kidney function — but this is a harmless, expected by-product of more creatine in the body, not a sign of kidney damage. In healthy people, the large body of research has not shown creatine to harm kidney function. The genuine caveat: if you have existing kidney disease or risk factors, talk to your GP first — and tell any doctor interpreting your blood tests that you take creatine, so they read the creatinine correctly.
Myth 2: "Creatine is a steroid"
It isn't — not chemically, not functionally. Creatine is a naturally occurring compound made from amino acids and found in everyday foods like meat and fish. Anabolic steroids are synthetic hormones; creatine is nothing of the kind. It's also permitted in sport and not a banned substance. This myth is simply a category error.
Myth 3: "Creatine causes hair loss"
This one traces back to a single small study suggesting a change in a hormone (DHT) — but it didn't actually measure hair loss, and it hasn't been reliably replicated since. The honest position: there's no solid evidence that creatine causes hair loss. It's a widely repeated claim built on very thin foundations.
Myth 4: "Creatine makes you fat / is just water weight"
Creatine draws a little water into the muscle, so some people see a small, early change on the scale — that's water within muscle, not body fat. It's a harmless, well-understood effect, and not the same as gaining fat. Being clear: this is a mechanism explanation, not a body-composition claim.
Who should check with a GP first?
Creatine is among the most-studied supplements and is well-tolerated by most healthy adults, but it's sensible to speak to your GP before starting if you: have kidney or liver conditions, are pregnant or breastfeeding, are under 18, or take medication. Responsible use beats blanket reassurance.
The takeaway
The big creatine fears — kidneys, steroids, hair loss — don't hold up to the evidence for healthy adults, though existing health conditions always warrant a GP chat. We'd rather give you the honest, myth-busted facts than either hype or fear. If you want a clean, well-studied option, our Micronised Creatine Monohydrate is monohydrate, the most-researched form. For more, see our creatine for women over 40 guide.
Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. If you are pregnant, breastfeeding, taking medication or managing a medical condition (especially kidney or liver conditions), speak to your GP or pharmacist before starting a new supplement.
