Quick answer
What is creatine?
Creatine is a compound the body makes from amino acids and also obtains from foods such as red meat and fish. Most of it is stored in skeletal muscle, where it plays a role in energy supply during short, intense effort. As a supplement, creatine monohydrate is the standard, most-researched form. Creatine is one of the few sports-nutrition ingredients with authorised EU/UK claims: it "increases physical performance in successive bursts of short-term, high-intensity exercise", with the benefit obtained at a daily intake of 3g in adults doing high-intensity exercise. A typical routine is an optional loading phase followed by a maintenance dose of about 3–5g per day.
Key takeaways
- Creatine is made in the body and found in meat and fish; most is stored in muscle.
- Creatine monohydrate is the standard, most-researched form.
- Common approach: optional loading, then a maintenance dose of about 3–5g per day.
- Gummies and powder both deliver creatine — what matters is the creatine dose per serving.
- Authorised claim: creatine increases physical performance in successive bursts of short-term, high-intensity exercise (benefit at 3g/day, adults doing high-intensity exercise).
- Authorised claim: daily creatine can enhance the effect of resistance training on muscle strength in adults over 55 (see conditions below).
The basics
What creatine actually is
Creatine is a naturally occurring compound made in the body from the amino acids glycine, arginine and methionine, mainly in the liver and kidneys. You also get it from the diet — red meat and fish are the richest sources. Around 95% of the body's creatine is stored in skeletal muscle, largely as phosphocreatine, where it is involved in rapidly regenerating ATP during short bursts of intense effort.
As a supplement, creatine is used to top up muscle creatine stores beyond what diet alone typically provides — which is part of why it is popular with people doing high-intensity training. It is sold as a food supplement in the UK. Unusually for a sports ingredient, some creatine claims are authorised for use on labels and marketing, provided the stated conditions are met — we set those out precisely further down this page.
Made in the body, found in meat and fish, and stored where it is used most — the muscle.
On the label
Creatine forms & formats
You will see creatine sold under several chemical forms and in different formats. The most important point: creatine monohydrate is the standard — it is the form used in the overwhelming majority of research and the reference against which others are compared. Newer forms are often marketed as "more soluble" or "better absorbed", but monohydrate remains the benchmark for value and evidence. Formats (powder, gummies, capsules) are simply different ways to deliver the same creatine.
| Form / format | What it is | Notes |
|---|---|---|
| Creatine monohydrate | Creatine bound to a water molecule | The standard, most-researched form. The reference point for dosing and value. |
| Micronised monohydrate | Monohydrate milled to a finer powder | Same molecule; finer particles mix more easily in liquid. |
| Creatine HCl | Creatine bound to hydrochloride | More water-soluble; marketed for smaller servings. Less researched than monohydrate. |
| Powder | Loose creatine you mix into liquid | Lowest cost per gram; easy to adjust dose. |
| Gummies | Chewable servings with a fixed dose | Convenient, no mixing, measured dose per serving (e.g. 3g). Check the creatine content. |
| Capsules | Pre-measured creatine in capsules | Convenient; you may need several capsules to reach 3–5g. |
Whichever format you choose, the number that matters is the creatine dose per serving. Gummies and powder can be equally valid — gummies trade a little cost for convenience and a fixed, no-mixing dose, while powder is the most economical and easiest to scale. Just confirm the label states the actual grams of creatine per serving.
Different formats, same goal: reach your daily creatine dose reliably.
How people dose it
Loading vs maintenance
There are two common approaches to creatine dosing. Both are widely used; neither is compulsory.
| Approach | Typical routine | Notes |
|---|---|---|
| Loading phase (optional) | ~20g/day split into 4 servings for 5–7 days | Fills muscle creatine stores faster. Optional — you can skip it. |
| Maintenance | ~3–5g/day, every day | The steady daily dose most people settle on. 3g/day is the level tied to the authorised claims. |
| No-loading approach | ~3–5g/day from the start | Reaches the same stores over a few weeks without a loading phase. |
Consistency matters more than timing — creatine works by keeping muscle stores topped up, so a daily habit is the point. Taking it with water and staying hydrated is sensible. A daily intake of 3g is the level associated with the authorised claims described below.
The authorised claims
What you may say about creatine
Creatine is one of the few sports-nutrition ingredients with authorised health claims under GB/EU rules. These may be used only when their specific conditions are met. We state them here exactly, with those conditions:
Physical performance
"Creatine increases physical performance in successive bursts of short-term, high-intensity exercise." Condition: the beneficial effect is obtained with a daily intake of 3g of creatine. This claim applies to adults performing high-intensity exercise.
Muscle strength in over-55s
"Daily creatine intake can enhance the effect of resistance training on muscle strength in adults over the age of 55." Conditions: the beneficial effect is obtained with a daily intake of 3g of creatine, in combination with resistance training that progressively increases muscle load. It applies only to adults over 55 doing regular resistance training.
Outside of these authorised statements and their conditions, we keep to the facts: what creatine is, its forms, and how it is dosed. If a product does not provide 3g of creatine per day, the claims above should not be applied to it.
Common questions
Creatine FAQ
Creatine monohydrate is the standard and the most-researched form, and it is the reference used for the authorised claims. Other forms such as creatine HCl exist and are marketed on solubility, but monohydrate remains the benchmark for evidence and value.
A common routine is an optional loading phase (about 20g/day split over 5–7 days) followed by a maintenance dose of about 3–5g per day, or simply 3–5g/day from the start with no loading. A daily intake of 3g is the amount tied to creatine's authorised claims. Consult a healthcare professional before starting any supplement.
Both deliver creatine — what matters is the creatine dose per serving. Gummies offer a fixed, no-mixing dose (for example 3g per serving) and convenience, while powder is usually the most economical and easiest to adjust. Check that the label states the actual grams of creatine per serving.
Two authorised claims exist. Creatine increases physical performance in successive bursts of short-term, high-intensity exercise (benefit obtained with 3g/day, for adults doing high-intensity exercise). And daily creatine intake can enhance the effect of resistance training on muscle strength in adults over 55 (with 3g/day plus progressive resistance training, in that age group). These may be used only when their conditions are met.
Cycling is not required for the way creatine works — the goal is to keep muscle stores topped up, so most people take it consistently every day. Staying well hydrated is sensible. As with any supplement, consult a healthcare professional if you have questions about your own situation.
As a general precaution, creatine is not recommended for anyone under 18, or during pregnancy or breastfeeding, and anyone taking medication or managing a health condition (particularly involving the kidneys) should speak to a healthcare professional first. Introduce one product at a time and follow the label serving.

This article is for general information about food supplements and is not medical advice. Creatine is sold as a food supplement in the UK. The authorised claims cited apply only when their stated conditions are met (a daily intake of 3g of creatine, and, for the strength claim, adults over 55 combining it with progressive resistance training). Always consult a qualified healthcare professional before starting any supplement, particularly if you are under 18, pregnant, breastfeeding, taking medication or managing a health condition.
