UK Creatine Buying Guide 2026: Form, Dose, Purity and Cost

Written by Barry Lees, Founder of The Health Improvers. Last reviewed 3 August 2026.

Short answer: for most shoppers, plain creatine monohydrate is the reference form. Compare the amount of actual creatine per daily serving, number of servings, ingredient list, manufacturing information and cost per serving. A larger “monohydrate” number is not always the same as the amount of creatine.

Commercial disclosure: We sell the creatine product used as the worked label example. This is a buying-method guide rather than a ranked survey of every UK brand.

What is creatine?

Creatine is made naturally by the body and is also present in foods including meat and fish. In muscle, creatine and phosphocreatine are involved in rapidly regenerating energy during short, intense work.

What may creatine legally claim in Great Britain?

The authorised wording is: creatine increases physical performance in successive bursts of short-term, high-intensity exercise. The claim may be used only for food providing a daily intake of 3g creatine, and consumers must be told that the beneficial effect is obtained with that daily intake. The target population is adults performing high-intensity exercise.

This does not authorise broad promises about general energy, fat loss, recovery, cognition or guaranteed muscle gain. In 2025, the GB register was updated to include a non-authorised proposed claim for creatine and cognitive function.

Why choose creatine monohydrate?

Monohydrate is the form with the largest evidence base. Reviews of alternative forms—including products marketed around solubility or absorption—have not established that another form consistently outperforms monohydrate. “Micronised” describes smaller particles and can help mixing; it is not a separate authorised benefit.

Does 5g creatine monohydrate mean 5g creatine?

No. Creatine monohydrate includes creatine plus one molecule of water. Creatine accounts for about 88% of the compound by mass. Our label declares both figures: one 5g serving of creatine monohydrate provides 4.4g creatine.

That distinction matters because the authorised claim’s condition is expressed as actual creatine. A label that shows only the monohydrate weight gives less direct comparison information.

Worked example: our creatine

Our Creatine Monohydrate Powder currently costs £24.99 for 500g:

• 5g creatine monohydrate per serving;
• 4.4g actual creatine per serving;
• 100 servings;
• one ingredient, without flavourings, sweeteners or fillers; and
• approximately £0.25 per serving at the current list price.

To compare daily cost, estimate when a pack will run out and plan when to reorder, use our free UK supplement cost and reorder planner. It works with any supplement and does not require an email address.

It is UK-made, vegan and Halal certified. The product page states that it is manufactured in an Informed Manufacturer facility; athletes should still distinguish a manufacturing-site programme from batch certification of a particular finished product.

Is Creapure® necessary?

Creapure® is a branded source of creatine monohydrate. Brand, origin and testing can be useful quality information, but the name does not change the authorised claim or prove that an unbranded monohydrate cannot meet specification. Compare documentation and finished-product information rather than treating one trademark as the only acceptable form.

Who should get individual advice?

People with kidney disease, abnormal kidney tests, a medically prescribed diet, pregnancy or breastfeeding, or relevant medication use should ask an appropriate healthcare professional before supplementing. Creatine can raise serum creatinine modestly without necessarily reducing measured filtration, which can complicate interpretation of kidney blood tests. Tell the clinician that you use creatine.

Seven questions before buying

1. Is the form creatine monohydrate?
2. How much actual creatine is supplied per daily serving?
3. Does it meet the 3g condition for the authorised performance claim?
4. How many full daily servings are in the pack?
5. What is the cost per serving?
6. Are flavours, sweeteners or other active ingredients included?
7. Are manufacturing and testing statements described precisely?
