Creatine: what science actually says (and what's a myth)
In my line of work, bad information costs dearly. In your training, too. Few supplements have as much evidence as creatine — and few carry as many myths. Let's separate fact from smoke.
What it does
Creatine raises your muscles' phosphocreatine stores — the immediate energy system for short, intense efforts. Exactly what you use in a heavy set, a sprint, or when you need to neutralize three threats in ten seconds. Meta-analyses show consistent gains in strength and lean mass when combined with resistance training, plus growing evidence for cognitive function under sleep deprivation. Interesting for someone who lives the night, isn't it?
How to take it
- Dose: 3 to 5 g per day, every day. That simple.
- Loading (20 g/day for 5–7 days) is optional. It fills the stores faster, but the standard dose reaches the same place in 3–4 weeks.
- Timing doesn't meaningfully matter. Consistency does. Take it with a meal to anchor the habit.
- Monohydrate. The "advanced" versions cost more and deliver nothing extra. The science is clear: monohydrate is the gold standard.
Myths I've already taken down
"Creatine destroys your kidneys." In healthy people, decades of studies show no kidney damage at recommended doses. It raises creatinine — a lab marker, not a disease — which confuses tests, not organs. Anyone with pre-existing kidney disease needs medical supervision, period.
"Creatine makes you retain water and look bloated." The extra water goes inside the muscle, not under the skin. That's cellular hydration, not bloat.
"It's a steroid." No. It's a natural compound found in meat and fish. No forensic lab in the world would classify creatine as a steroid.
"You need to cycle it." There's no evidence that pausing helps. The body maintains its own production.
The Lair's verdict
If you train for strength and chase performance, creatine monohydrate is probably the best cost-benefit investment on the market. Cheap, safe for healthy people, with a real effect — the kind of ally I accept on my team.
How to choose creatine at the store
A crowded shelf is an ambush. What to separate before you buy:
- Pure creatine monohydrate: the only ingredient you need. Distrust "turbo" blends with sugar and loose amino acids — you pay more for less.
- Creapure seal: German raw material with certified purity. Not mandatory, but an extra guarantee against contaminants.
- Price per gram: divide the tub price by total grams. Small "cheap" tubs often cost more per dose than big ones.
- Third-party testing: serious brands publish purity reports. Transparency signals an honest product.
- Micronized or regular? Micronized dissolves better in liquid; the effect in the muscle is identical.
Creatine across life stages
- Vegetarians and vegans: tend to have lower stores (dietary creatine comes from meat and fish) and often respond even better to supplementation.
- Older adults: combined with strength training, creatine helps preserve muscle mass and strength — an ally against sarcopenia, always with medical clearance.
- Teenagers: the consensus is to prioritize food, training and sleep; supplementation at that age only with individualized professional guidance.
Common mistakes that cancel the effect
- Taking it "when you remember": the effect comes from a full muscle store, which demands daily consistency.
- Expecting instant results: without a loading phase, stores fill in 3 to 4 weeks. Patience is part of the protocol.
- Forgetting water: creatine pulls water into the muscle; hydrate accordingly.
- Judging by the scale: the initial 2-4 lb gain is intracellular water — a sign it's working, not fat.
Frequently asked questions
Does creatine cause acne? There's no evidence supporting that link at recommended doses.
Can I take it with coffee? Yes. The idea that caffeine "cancels" creatine didn't hold up in modern studies.
Should I stop before blood tests? Tell your doctor you supplement: creatinine can come back slightly elevated without meaning kidney trouble.
Does creatine make you fat? It adds no fat. The 2-4 lb bump is water inside the muscle.
What's the best time to take it? Whichever time you won't forget. Consistency beats timing.
