Last updated: 1 June 2026 · 10 products reviewed
Creatine monohydrate is the most researched sports supplement in existence — proven to increase strength, power and high-intensity performance. But it's also a commodity: the molecule is identical across brands, so the real differences come down to purity, dosing, banned-substance testing and price. We ranked the 10 best creatine supplements in the UK across all four factors so you can find the right one.

Detailed Reviews & Rankings
Reflex Nutrition's Creapure creatine is our gold-standard pick — the same German-made >99.9% purity creatine used by premium brands worldwide, Informed-Sport certified, dosed at the research-backed 5g, and priced sensibly.
Pros
- Uses Creapure® — the German >99.9% purity gold standard
- Informed-Sport certified (tested for 190+ banned substances)
- 5g per serving matches clinical research protocols
Cons
- Slightly more expensive than non-Creapure generics
- Powder form requires a scoop and shaker
- Unflavoured can be slightly gritty if under-mixed
Myprotein delivers genuine Creapure creatine at roughly 40% less than premium brands. The only catch is the 3g serving size — you'll want to take a bit more to match the research-backed 5g dose.
Pros
- Creapure® sourcing at a much lower price than premium brands
- Micronised for better mixability
- Widely available with frequent discounts
Cons
- 3g serving is below the 5g research standard — needs more for full saturation
- Loading phase recommended to reach saturation quickly
- Quality control occasionally questioned at scale
Warrior offers pure micronised creatine monohydrate at the full 5g research dose without the Creapure premium. Quality is equivalent to branded creatine and the price is keen.
Pros
- Pure micronised monohydrate at the research-backed 5g dose
- Good mixability thanks to micronisation
- Third-party tested with GMP manufacturing
Cons
- Not Creapure-branded (though quality is equivalent)
- Less brand heritage than Reflex
- Sourcing origin less publicised
Naughty Boy delivers genuine Creapure at the full 5g dose for a competitive price — a strong choice, though it lacks the brand heritage and banned-substance testing of our top pick.
Pros
- Creapure® sourced at a competitive price
- Full 5g research-backed serving
- Popular with the bodybuilding community
Cons
- Less established than heritage brands
- Not Informed-Sport certified
- Limited retail availability outside Amazon
Applied Nutrition's capsule creatine trades value for convenience. Great if you hate mixing powder, but you'll pay a premium and swallow a lot of capsules to hit a proper dose.
Pros
- Convenient capsule format — no mixing or scoop needed
- GMP certified with good transparency
- Established UK sports nutrition brand
Cons
- Capsules cost more per gram than powder
- Requires 6 capsules to reach 3g — more for 5g
- Lower dose per serving than powder options
Optimum Nutrition's creatine is reliable and well-dosed, but it's generic monohydrate sold at a premium price thanks to the brand. Equivalent quality is available cheaper elsewhere.
Pros
- Trusted global brand with strong reputation
- Full 5g research-backed serving
- Micronised for mixability
Cons
- Generic monohydrate, not Creapure, yet priced at a premium
- More expensive than equivalent-quality competitors
- You're partly paying for the brand name
CLN Labs offers UK-made creatine at the full 5g dose for a low price. Appealing for UK-manufacturing fans, though the purity spec isn't clearly documented.
Pros
- UK-made at a competitive price
- Full 5g serving
- Good value per gram
Cons
- Purity specification not clearly stated (not confirmed Creapure)
- Smaller brand with less testing transparency
- Limited availability
Bulk's Creapure creatine is among the cheapest genuine Creapure you can buy in the UK. The trade-off is loose-bag packaging that makes measuring messier than a tub.
Pros
- One of the cheapest Creapure options available
- Full 5g serving and 100 servings per bag
- Informed-Sport options available in some lines
Cons
- Loose powder in a bag — measuring less precise, wastage risk
- Resealable bag less convenient than a tub
- Lower transparency on batch testing
NXT Nutrition offers genuine Creapure at the full 5g dose, but the smaller tub size makes it less cost-effective than larger Creapure options.
Pros
- Creapure sourced
- Full 5g serving
- Mid-range pricing
Cons
- Smaller tub (50 servings) means less value per pound
- Less established brand
- Limited testing transparency
Generic Amazon creatine is cheap and usually works, but with unknown sourcing, inconsistent purity, and no testing transparency, it's a gamble we can't recommend over verified options.
Pros
- Cheapest option available
- Often large tub sizes
- Creatine monohydrate is hard to get badly wrong
Cons
- Unknown sourcing and inconsistent purity
- Minimal or no third-party testing
- No banned-substance certification — risky for tested athletes
How to Choose a Creatine Supplement
Creatine Is a Commodity — Here's What Actually Matters
Creatine monohydrate has the same chemical formula (C₄H₉N₃O₂) regardless of brand, and all quality monohydrate delivers the same physiological results. So what differentiates products? Purity (Creapure vs generic), dosing (3g vs the research-backed 5g), banned-substance testing (Informed-Sport for athletes), and price. Don't overpay for marketing — focus on these four factors.
Why Creapure Matters
Creapure is creatine monohydrate manufactured by AlzChem in Germany to over 99.9% purity. Its proprietary process removes contaminants like creatinine and dicyandiamide that can appear in cheaper creatine. It costs a few pounds more, but it's the form trusted by premium brands and the safest choice for purity-conscious buyers.
Dosing: 3g vs 5g and Loading
Clinical research uses 5g of creatine daily. Some products are labelled at 3g, which means you'll need to take more or wait longer to saturate your muscles. A loading phase (20g/day for 5–7 days) saturates faster but isn't required — 5g daily reaches full saturation in about 3–4 weeks. Benefits fade after 3–4 weeks off, so consistency matters more than any brand.
Powder vs Capsules
Powder is far better value — around 15p per 5g serving versus 25p+ for capsules, and you'd need around 10 capsules to match a 5g powder dose. Capsules win only on convenience and travel. Micronised powder mixes better but absorbs the same — your body takes up creatine at the intestinal level regardless of particle size.
Creatine FAQ
What is the best creatine in the UK?
Reflex Nutrition Creapure is our top pick — Creapure purity, Informed-Sport certified, 5g research dose, great value. Myprotein is the best budget option using the same Creapure at a lower price.
Is Creapure worth the extra cost?
For most people, yes. Creapure guarantees over 99.9% purity and removes impurities found in cheaper creatine. The price gap is small, and it's the safest choice — especially if you're a drug-tested athlete and choose an Informed-Sport certified Creapure product.
How much creatine should I take daily?
5g daily is the research-backed dose. You can optionally load with 20g/day (split into 4 doses) for 5–7 days to saturate faster, then maintain at 5g. Consistency is key — benefits build over 3–4 weeks and fade if you stop.
Powder or capsules — which is better?
Powder is much better value and lets you hit the full 5g dose easily. Capsules are more convenient for travel but cost more per gram and require many capsules to reach an effective dose.
Does creatine cause water retention?
Creatine draws water into muscle cells, which can cause a small increase in body weight (1–2kg) early on. This is intramuscular water, not bloating, and is part of how creatine works. It's harmless and often accompanies fuller-looking muscles.
