Cheap, proven, and everywhere right now — here’s the honest breakdown.
Creatine’s having a proper moment. It’s gone from “meathead powder” to a mainstream staple, with Gen Z and millennials buying it for everything from gym gains to general wellness — and new formats like gummies flooding the shelves. But cutting through the hype: is the plain stuff actually worth your hard-earned tenner? Let’s get into it.
Quick note up front: this is general information, not medical advice. If you’ve got a health condition (especially kidney issues), are under 18, pregnant, or on medication, talk to a doctor or pharmacist before starting anything.
What It Is
Creatine is a compound your body already makes from amino acids, stored mostly in your muscles. During short, hard bursts of effort — a heavy set, a sprint, HIIT — it helps regenerate ATP, your muscles’ main energy currency. Supplementing tops up those stores so you can squeeze out a bit more work before fatigue kicks in.
The gold-standard form is creatine monohydrate. It’s the one that’s been studied to death, and there’s no strong evidence the fancier (pricier) forms beat it.
What the Evidence Actually Says
Creatine monohydrate is one of the most researched supplements out there, and the consensus from sports dietitians is genuinely positive — for the right goal.
- For improving strength and power in high-intensity training (weightlifting, HIIT, short sprints under ~30 seconds), the evidence supporting creatine is robust.
- Standard maintenance dose is around 3–5g per day. A “loading phase” (roughly 20–25g/day split over 5–7 days) saturates your muscles faster, but it’s optional — you get there either way, just slower without it.
- On safety: at recommended doses, current evidence shows no documented harm to kidneys, liver or other organs in healthy people. Concerns tend to centre on very high-dose, long-term use, and remain an area of ongoing research rather than proven danger.
Important caveat: creatine is an enhancer, not a shortcut. Dietitians are clear that calories, protein, and sleep come first. It won’t rescue a poor diet or patchy training — it adds a small edge on top of the fundamentals.
Honest Pros
- Strong, consistent evidence for strength and power gains
- Dirt cheap per serving (more on that below)
- Simple, no proprietary-blend mystery ingredients
- Doesn’t need to be timed perfectly — just take it daily and stay consistent
- No stimulants, so it won’t wreck your sleep like a pre-workout might
Honest Cons / Caveats
- Not a magic pill — the effect is modest and only shows up alongside proper training and diet
- Some people carry a little extra water weight early on (usually harmless, but worth knowing)
- A minority get mild stomach upset, especially when loading — spreading doses or skipping the load helps
- Benefits are mainly for short, explosive efforts — don’t expect much for pure endurance
- Quality varies: look for third-party tested products (e.g. Informed Sport / NSF Certified for Sport) to avoid contamination, particularly if you get drug-tested
- If you have any kidney condition or take medication, check with a professional first
Cost-Per-Serving / Is It Worth the Money?
This is where creatine shines for the Skint Gains crowd. Buy a plain creatine monohydrate powder in a decent-size tub and you’re typically looking at just a few pence per 5g serving — one of the best value-for-evidence buys in the whole supplement aisle.
Compare that to:
- Creatine gummies — trendy and convenient, but you pay a hefty premium per gram, and you’ll want to check they actually contain a proper dose
- Fancy “advanced” creatine forms — more expensive with no proven advantage over plain monohydrate
- Pre-workouts — often built around caffeine you could get from a 30p coffee
For a budget gym-goer, the plain powder is the clear value winner. Skip the gummies and the marketing.
The Verdict
If you’re lifting for strength or power and your diet and sleep are already halfway sorted, creatine monohydrate is about as close to a no-brainer as supplements get. It’s cheap, it’s proven, and it doesn’t hide behind mystery blends. Buy a big tub of plain powder, take 3–5g a day, keep it consistent, and ignore the flashier (pricier) versions dressed up in gummy form. Just don’t expect miracles — it’s a small edge on top of the hard work, not a substitute for it.
