If you asked a room full of researchers to name one supplement with genuinely strong evidence behind it, a lot of them would say creatine. It’s cheap, it’s been studied for decades, and it does something specific and measurable. Yet it’s still wrapped in myths — that it’s a steroid, that it “bloats” you, that it’s only for bodybuilders. Let’s clear all that up and cover exactly how to use it.
What creatine actually is
Creatine is a compound your body already makes from amino acids, and that you already eat in small amounts in meat and fish. It’s stored mostly in your muscles, where it helps regenerate ATP — the fast energy your muscles use for short, intense efforts. Supplementing simply tops up those stores, so your muscles have a little more of that quick energy on tap.
That’s it. It’s not a hormone, it’s not a stimulant, and it’s not “artificial” in any meaningful sense. It’s one of the most naturally occurring compounds you can supplement.
What the research suggests it does
The best-supported benefit is for strength and power: research consistently links creatine supplementation with improvements in high-intensity performance and, over time, gains in muscle strength and size when paired with resistance training. It’s not a magic powder — you still have to do the work — but it may help you do a little more work, which compounds over months.
There’s also growing (though earlier-stage) research into creatine and cognition, especially under sleep deprivation or stress, and interest in its role for women and older adults maintaining muscle. We’d call those promising rather than settled.
The famous myths, briefly
“It’s a steroid.” No. Steroids are hormones; creatine is an amino-acid compound. They have nothing in common beyond both being used in gyms.
“It makes you fat.” Creatine can pull a little extra water into your muscle cells early on, which may nudge the scale up a kilo or so. That’s intramuscular water, not fat, and many people don’t notice it at all.
“You have to cycle it.” There’s no strong evidence you need to. Consistent daily use is the simplest approach.
How to take it
Here’s the genuinely simple part:
- Dose: 3–5g per day. That’s the maintenance dose used in most research.
- Loading (optional): Some people take ~20g/day split into 4 doses for the first 5–7 days to saturate muscles faster, then drop to 3–5g. It works, but it’s not necessary — daily 3–5g gets you to the same place in a few weeks.
- Timing: It barely matters. Daily consistency is what fills your stores, so take it whenever you’ll remember. With food is fine.
- Form: Plain creatine monohydrate is the winner. It’s the most studied, the cheapest, and the “fancier” forms haven’t been shown to beat it. Look for a plain, ideally micronised, monohydrate powder — you don’t need anything else added.
- Hydration: Drink your normal water. You don’t need to force liters.
- Best value monohydrate: creatine monohydrate powder, micronised
- Capsule option (if powder isn’t your thing): creatine monohydrate capsules
- Unflavoured to mix into anything: pure creatine monohydrate, unflavoured
Who it suits (and who should check first)
Creatine suits most people doing resistance training or higher-intensity exercise, and increasingly it’s considered for anyone trying to maintain muscle with age. Vegetarians and vegans sometimes notice a bigger effect, since they get less creatine from food.
As always, if you have kidney issues, are pregnant or nursing, or take medication, check with your doctor or pharmacist first — not because creatine is risky for most healthy people, but because “most” isn’t “everyone.”
The honest bottom line
Creatine monohydrate is boring in the best way: well-studied, inexpensive, and effective for a specific job. Take 3–5g a day, stay consistent, keep training, and give it a couple of months. That’s the whole strategy.
