Best Creatine UK 2026: Honest Rankings by Cost, Purity, and Third-Party Testing
The best creatine in the UK is plain creatine monohydrate, and the best value is Protein Works Creatine Monohydrate at 10p per 5g serving, against about 42p per 5g for Creapure tubs. Nothing has beaten monohydrate in the research, so pay more only if you need third-party testing.

Quick answer
The best creatine to buy in the UK is plain creatine monohydrate, and the best value is Protein Works Creatine Monohydrate at 10p per 5g in the 1kg bag (£19.99), the cheapest from a major brand in our price data. There is no need to pay for HCL or fancy blends, since nothing has beaten monohydrate in the research. If you are drug-tested, MyProtein Impact Creatine is Informed Choice certified at 14p per 5g. Take 3 to 5g a day, every day. WheyWise compared every price across UK retailers.
The best-value creatine in the UK is Protein Works Creatine Monohydrate at 10p per 5g serving, and the UK market runs from there up to about 42p per 5g for Creapure tubs. Creatine monohydrate is the single most evidence-backed supplement in the sports nutrition stack, with consistent gains in strength, power output, and muscle mass at a daily dose of 3 to 5 grams. The right pick depends on three factors: how much you want to spend, whether you need third-party testing, and whether you want Creapure. Wondering whether you can mix creatine with protein? Yes, and our guide on adding creatine to your protein shake covers how and what it costs.

What actually matters when choosing creatine
Four criteria matter when ranking creatine products. Everything else on a label is marketing.
- Form. Creatine monohydrate is the standard, and the head-to-head research has not found a form that beats it on strength, hypertrophy, or power output. Creatine HCL is more water-soluble but no better on outcomes. Kre-alkalyn and ethyl ester have no meaningful evidence base.
- Cost per 5 gram dose. The daily saturation dose is 3 to 5 grams. Ranking by tub price hides the serving-size trade-off: MyProtein Impact Creatine and Optimum Nutrition's UK tub both use a serving of about 3.4g of creatine monohydrate. Run the maths on cost per 5 gram serving to compare fairly.
- Third-party testing. Creapure guarantees at least 99.9 percent purity, and Informed Sport and Informed Choice batch-test finished products for banned substances. A generic tub with no third-party certification may still be fine but carries no verification. Only 8 percent of 175 creatine products on Amazon.com were third-party certified in a 2022 audit (Escalante et al., 2022).
- Micronisation. Micronised creatine mixes cleanly into water, protein shakes, or juice without clumping or settling to the bottom of the shaker. Standard monohydrate can leave visible grit. Optimum Nutrition's creatine is micronised, and Protein Works describes its powder as ultra-fine 200 mesh.
Best budget creatine UK
Protein Works Creatine Monohydrate is the cheapest creatine monohydrate from a major UK brand in our price data, at 10p per 5g in the 1kg bag for £19.99. The 500g bag is £10.49 (10.5p per 5g) and the 250g is £6.99 (14p per 5g), and it comes unflavoured or in Berry Blitz and Orange Burst. Protein Works code WW12 takes 12% off most one-off orders.

Pros
- + 10p per 5g in the 1kg bag at £19.99
- + Ultra-fine 200 mesh powder, so it mixes cleanly
- + Unflavoured, Berry Blitz or Orange Burst
Cons
- – No Creapure source or batch-testing certification stated
- – The 250g tub costs 14p per 5g, so buy the 500g or 1kg
The trade-off is testing. Protein Works does not state a Creapure source or a batch-testing certification for this product, which is fine for most recreational lifters but not for anyone subject to drug testing.
Best mainstream creatine UK
MyProtein Impact Creatine is the best mainstream pick because it is Informed Choice certified for banned substances and still cheap: £27.99 for 1kg on myprotein.com (14p per 5g) or £15.99 for 500g (16p per 5g). Each 3.4g serving gives 3.0g of creatine, so take about one and a half scoops for a full 5g. Flavours include Berry Burst, Blue Raspberry, Tropical, Vimto and Chupa Chups.

Pros
- + Informed Choice certified for banned substances
- + 14p per 5g in the 1kg tub, 16p in the 500g
- + The widest flavour range of the picks here
Cons
- – The 3.4g scoop is below a 5g dose
- – 40% dearer per gram than Protein Works in the 1kg size
Optimum Nutrition Micronised Creatine Powder is the other mainstream option, sold on Amazon UK and on the high street. In the UK each 3.6g scoop gives 3.4g of creatine monohydrate, and the 634g tub costs £27.98 on Amazon UK (22p per 5g), with the 317g at £15.99 (25p per 5g). It mixes cleanly, but it costs more than twice as much per 5g as Protein Works and its UK product page makes no certification claim.
Best premium creatine UK (Creapure)
Reflex Creapure Creatine is the cheapest way to buy Creapure in the UK in our price data, at £21.99 for 500g on Amazon UK, or 22p per 5g. Creapure is creatine monohydrate made by AlzChem at its Trostberg plant in Germany, which it says is at least 99.9 percent pure with no detectable DHT and under 20 mg/kg of DCD.

Pros
- + Creapure creatine monohydrate from AlzChem in Germany
- + 22p per 5g in the 500g tub at £21.99
- + Unflavoured, nothing else in the tub
Cons
- – More than double the price per 5g of Protein Works
- – The 250g tub is far worse value at £18.99
The premium is real. MyProtein THE Creatine, the Creapure tub from MyProtein, is £42.49 for 500g on myprotein.com, or 42p per 5g, about three times the price per gram of Impact Creatine in the 1kg tub, and Bulk Creapure Creatine is £41.99 for 500g on bulk.com. Over a year of daily 5 gram dosing, even the cheapest Creapure costs about £44 more than Protein Works.
That premium buys a documented purity specification and batch traceability, not extra performance. For a competitive athlete, an Informed Sport or Informed Choice batch-tested tub matters more than the Creapure name. See the dedicated Creapure vs Generic Creatine Monohydrate post for the full purity data.
Best creatine HCL for tolerance-focused users
Bulk Creatine HCL is the creatine HCL to try if monohydrate genuinely upsets your stomach, at £17.99 for 500g on bulk.com. That is 64% more per gram than Bulk Creatine Monohydrate at £10.99 for 500g, and MyProtein's HCL costs 91% more than Impact Creatine. The research shows no performance advantage for HCL over monohydrate; the legitimate use case is digestive tolerance, if it is the difference between consistent daily dosing and stopping creatine entirely.
Best creatine HCL
Bulk Creatine HCL Powder - Creatine Hydrochloride - Fast Absorbing - High Intensity Workout - Post Workout Creatine
500g bag
The HCL to try if monohydrate genuinely disagrees with you, and only then.
Pros
- + Dissolves fully in water, with no grit
- + £17.99 for 500g, the cheaper of the two HCLs we track
- + 3g serving on the label
Cons
- – 64% dearer per gram than Bulk Creatine Monohydrate
- – No trial shows HCL builds more strength or muscle than monohydrate
For anyone who tolerates monohydrate without issues, HCL is not worth the premium. See Creatine Monohydrate vs HCL for the full breakdown of the solubility argument and why it does not translate to better results.
How to take creatine for best results
The creatine protocol is simple. Three to five grams per day, taken every day, indefinitely. Timing does not matter for the saturation model; pick a time you will remember (post-workout protein shake is the most common default). Loading phases (20 to 25 grams per day for 5 to 7 days) accelerate muscle saturation by two to three weeks but are optional. Most users reach full saturation at 3 to 5 grams per day after about 3 to 4 weeks of consistent dosing.
Expected results timeline:
- Week 1 to 2: 1 to 2 kilograms of scale weight increase from intracellular water retention. This is the intended effect, not fat.
- Week 2 to 4: Small strength improvements begin appearing on heavy compound lifts. Typically 2 to 5 percent improvement at saturation.
- Week 4 to 8: Full saturation reached. Strength gains compound with training progress. Muscle fullness noticeably improved.
- Long-term: Stable performance benefit as long as daily dosing continues. Decays back to baseline over 4 to 6 weeks if stopped.
See the dedicated How Much Creatine Per Day post for the dosing deep dive.
Common questions about creatine in the UK
Is creatine legal in the UK?
Yes. Creatine monohydrate is fully legal in the UK and is not a banned substance under UK Anti-Doping Agency rules or World Anti-Doping Agency guidelines. It is legal to buy, sell, import, and consume without restriction.
Do I need to cycle creatine?
No. Creatine does not require cycling. Long-term continuous use (years or decades) is safe and well-researched. Cycling creatine produces no performance benefit and creates the 4 to 6 week re-saturation window every time you restart.
Is creatine safe for kidneys?
Yes for healthy adults. The kidney safety concern traces to a single 1998 case report that has not been replicated in the two decades since. Multi-year studies in healthy adults taking 3 to 10 grams per day show no adverse impact on kidney function markers. Users with pre-existing kidney disease should consult their GP before starting any supplement.
Can I take creatine with protein powder?
Yes. Mixing creatine into a post-workout protein shake is the most common approach in the UK and is supported by research showing the insulin response to carbs and protein may slightly improve creatine uptake into muscle. The combined shake has no negative interactions.
Do women need less creatine than men?
Slightly, on average, but not enough to change the protocol. Smaller users (under 60kg) reach saturation comfortably at 3 grams per day. Larger users may benefit from 5 grams. Gender is a weak predictor; body mass is the better one. Women benefit from creatine identically to men on strength, muscle, and cognitive performance markers.
