Best Creatine UK: Top Picks, Prices and What to Buy

1. 1

   Best budget creatine UK: MyProtein Impact Creatine. Cheapest per 5 gram dose during flash sales, with no Informed Sport certification but pharmaceutical-grade monohydrate.

2. 2

   Best mainstream creatine UK: Optimum Nutrition Micronised Creatine Powder. Informed Choice certified, widely stocked, excellent mixability, mid-tier pricing.

3. 3

   Best premium creatine UK: MyProtein THE Creatine (Creapure). Creapure-certified at 99.99 percent purity, Informed Sport tested, the right pick for competitive athletes.

4. 4

   Best creatine HCL UK: MyProtein Creatine HCL. Appropriate only for users who have failed monohydrate on digestive tolerance. Costs 2 to 3 times more than monohydrate with no performance advantage.

Four criteria matter when ranking creatine products. Everything else on a label is marketing.

1. 1

   Form. Creatine monohydrate is the standard. Every creatine comparison study published since 2005 confirms monohydrate matches or exceeds alternative forms on strength, hypertrophy, and power output. Creatine HCL is more water soluble but no better on outcomes, and kre alkalyn and ethyl ester have no meaningful evidence base.

2. 2

   Cost per 5 gram dose. The daily saturation dose is 3 to 5 grams. Ranking by tub price hides the serving size trade off, since Optimum Nutrition doses at 5 grams per scoop while MyProtein doses at 3 grams per scoop. Doing the maths on cost per 5 gram serving is the only fair comparison.

3. 3

   Third-party testing. Creapure certification guarantees 99.99 percent purity, and Informed Sport tests for banned substances. Informed Choice tests for banned substances but not purity. A generic tub with no third-party certification may still be fine but carries no verification. Only about 8 percent of creatine products on Amazon advertise any third-party certification, according to a 2022 Amazon creatine audit (PMC9761713).

4. 4

   Micronisation. Micronised creatine mixes cleanly into water, protein shakes, or juice without clumping or settling to the bottom of the shaker, while standard monohydrate leaves visible grit. Every creatine in this guide is micronised, which filters out the cheapest overseas imports.

MyProtein Impact Creatine is the cheapest creatine monohydrate that still meets the baseline quality threshold in the UK. During MyProtein's frequent flash sales, including Impact Week, Black Friday, and January promotions, the 500g tub drops below £10, putting the cost per 5 gram dose under 12 pence. Full retail sits around £15, which remains competitive.

The trade offs are real but small. MyProtein doses Impact Creatine at 3 grams per scoop, which is saturation effective for most users but slightly below the 5 gram benchmark the research literature uses. There is no Informed Sport certification on the Impact line, though MyProtein manufactures in the UK under ISO 9001 quality control, and Reddit and Trustpilot reviews consistently rate Impact Creatine as the default budget pick for recreational lifters.

Flavoured variants such as Blue Raspberry, Vimto, and Chupa Chups exist for users who find unflavoured creatine unpleasant. The unflavoured version is the better pick if you add creatine to a protein shake or juice where the carrier already provides flavour.

Optimum Nutrition Micronised Creatine Powder is the most consistently recommended creatine on Reddit's r/Supplements and bodybuilding forums. It delivers 5 grams of creatine monohydrate per serving, carries Informed Choice certification for banned-substance testing, and mixes cleanly in water or shakes. A 317g tub delivers 63 servings at roughly £18 to £22, putting cost per 5 gram dose at around 30 pence.

The Informed Choice certification is what differentiates it from cheaper generic monohydrate. Informed Choice tests each batch for banned substances on the World Anti-Doping Agency prohibited list, which matters for club-level competitive athletes, though it does not test for purity specifically (DCD and DHT impurities), which is the gap Creapure fills.

Optimum Nutrition is available across Amazon UK, Holland and Barrett, supermarket sports aisles, and direct from the Optimum Nutrition UK site. That ubiquity is itself a reason it stays in heavy rotation, since buying creatine should not require a trip to a specialist retailer. The Elite Series variant costs more without a meaningful spec difference, so it is worth sticking with the standard Micronised Creatine Powder unless the Elite Series happens to be discounted below the standard price.

MyProtein THE Creatine is the right pick for competitive athletes and anyone who wants the highest verified purity available. It is Creapure certified, meaning the raw creatine monohydrate is produced by AlzChem at their Trostberg facility in Germany and verified at 99.99 percent pure creatine monohydrate by HPLC testing, and it carries Informed Sport certification for banned-substance testing.

The premium is real. THE Creatine retails at roughly twice the price of Impact Creatine per gram, with a cost per 5 gram dose of around 40 to 55 pence depending on tub size and sale timing. Over a year of daily 5 gram dosing, that works out to an extra £30 to £50 compared with Impact Creatine.

That premium buys three things: verified 99.99 percent purity with minimal DCD and DHT impurities, Informed Sport banned-substance testing, and the gentler digestive profile that Reddit users consistently report for Creapure over generic creatine. For someone training five days a week who takes creatine daily for 20 years, the cumulative exposure difference to impurities is not trivial, even if the per-dose difference is small.

See the dedicated Creapure vs Generic Creatine Monohydrate post for the full purity data.

Creatine HCL is worth considering only if you have previously tried creatine monohydrate, ideally micronised, and experienced persistent digestive discomfort that did not resolve. The research shows no performance advantage for HCL over monohydrate. The legitimate use case is digestive tolerance: some users report reduced bloating or stomach upset on HCL, which can justify the 2 to 3 times price premium if it is the difference between consistent daily dosing and giving up on creatine entirely.

For anyone who tolerates monohydrate without issues, HCL is not worth the extra cost. See Creatine Monohydrate vs HCL for the full breakdown of the solubility argument and why it does not translate to better results.

The creatine protocol is simple: 3 to 5 grams per day, taken every day, indefinitely. Timing does not matter for the saturation model, so pick a time you will remember, with a post-workout protein shake being the most common default. A loading phase of 20 to 25 grams per day for 5 to 7 days accelerates muscle saturation by two to three weeks but is optional. Most users reach full saturation at 3 to 5 grams per day after about 3 to 4 weeks of consistent dosing.

See the dedicated How Much Creatine Per Day post for the full dosing deep dive.

1. 1

   Week 1 to 2: 1 to 2 kilograms of scale weight increase from intracellular water retention. This is the intended effect, not fat gain.

2. 2

   Week 2 to 4: small strength improvements begin appearing on heavy compound lifts, typically 2 to 5 percent at saturation.

3. 3

   Week 4 to 8: full saturation reached. Strength gains compound with training progress, and muscle fullness is noticeably improved.

4. 4

   Long-term: a stable performance benefit as long as daily dosing continues, decaying back to baseline over 4 to 6 weeks if stopped.

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.

Creatine does not require cycling. Long-term continuous use, whether for years or decades, is safe and well-researched. Cycling creatine produces no performance benefit and simply creates a 4 to 6 week re-saturation window every time you restart.

For healthy adults, creatine is safe long-term. The kidney safety concern traces back 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 still consult their GP before starting any supplement.

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 carries no negative interactions.

Body size makes a modest difference, though not enough to change the protocol. Smaller users under 60kg reach saturation comfortably at 3 grams per day, while larger users may benefit from 5 grams. Body mass is a far better predictor than gender, and women benefit from creatine identically to men on strength, muscle, and cognitive performance markers.
