How to choose a creatine supplement

If you want the short answer before any nuance: choose creatine monohydrate. A recent critical review concluded that it remains the only form of creatine with substantial evidence of bioavailability, efficacy and safety, and the form recommended by professional bodies. Everything that follows on this page is there to explain why, what changes (and what does not) between forms, and what is worth checking on the label before you pay.

We are not going to promise you results. We do not know how your body will respond, and neither does anyone else. What we do know is what the research shows about the available forms — and that is what decides a sensible purchase.

What creatine is, in two sentences without the marketing

As a supplement, it is sold as a powder, a capsule, a tablet and, more recently, as a gummy. The chemical form in which creatine appears in the product is the first decision point, and it is also the point where most people get lost.

The confusion arises because the market treats 'creatine' as a single category, when it is in fact a family of compounds with different names: monohydrate, citrate, malate, nitrate, pyruvate, ethyl ester, magnesium creatine chelate, and so on. Each name is a different molecule or a different combination, and the evidence does not transfer from one to another.

Monohydrate or other forms: what actually differs

Here is what the comparative research found, and it is less exciting than the labels suggest. A systematic review of 17 randomised, placebo-controlled trials looked at the alternative forms that have already been studied: magnesium creatine chelate and creatine citrate, malate, ethyl ester, nitrate and pyruvate. Of those 17 trials, only 3 compared an alternative form directly with monohydrate. And there were no consistent performance benefits of the alternative forms over placebo.

Read that last sentence again, because it is the heart of the decision. If an alternative form does not consistently distinguish itself from placebo in the studies that have been done, there is no basis for paying more for it.

The same review found two practical facts that matter to anyone deciding with their wallet: monohydrate is the cheapest form on the market and the most studied. Expensive rarely means better in this market. It often means only a prettier package and a longer name.

And the claims made for 'new forms'?

The critical review we mentioned was direct on this point: it found no alternative form that was a more effective source than monohydrate, and noted that claims of greater efficacy or safety continue to be made without support. The same review recommends that anyone launching a new form should demonstrate bioavailability, efficacy and safety before claiming it is better — and observes that the forms on sale range from those with good evidence to those with none.

That leaves you with a simple rule to apply: when a label says its form is 'more absorbable' or 'does not cause water retention', it is making a claim that the available evidence does not support.

What does not differ, however much the label insists

There is no evidence that buffered, HCl or liquid creatine is better absorbed, requires a smaller amount or causes less bloating than monohydrate. The reviews consulted found no alternative form demonstrated to be superior, and the systematic review found only 3 direct comparisons. That is thin ground for a difference, and even thinner for charging for one.

On water retention, kidney function, liver function and hair loss: a recent narrative review by researchers in the field describes monohydrate as a safe and effective intervention for certain aspects of sport, performance and health, and addresses these questions as topics. We are not going to give you answers we have not read, so we will stop there: these are subjects under discussion, not arguments for or against a specific form.

Purity and independent testing

Here we have to be honest with you: the sources underpinning this page do not cover third-party testing or purity regimes. We are not going to tell you that any particular seal guarantees anything, because we do not know. If purity is your main concern, ask the manufacturer directly what tests they run and who runs them — and be wary of anyone who does not answer.

Do people use both forms? They do. Does that mean anything?

Yes, some people combine different forms, and some alternate between them. There is nothing in the evidence that allows us to say the combination works better, and we are not going to give you a combined dose — there is no basis for suggesting one. If you find a product that mixes several forms, treat that as a formulation choice by the manufacturer, not as a demonstrated advantage.

Who is well served by monohydrate — and who should think twice

For the overwhelming majority of people who simply want to take creatine, monohydrate solves the problem: it is the most studied, the cheapest and the only one with substantial accumulated evidence. You do not need to look for the 'premium' form. You need to look for a clear label.

There are, however, legitimate reasons to choose a format other than powder — and none of them has to do with the chemical form. If you do not like the taste, if you find measuring doses difficult, or if you simply know you will not use a powder every morning, a format you can stick to is better than the 'ideal' form that stays in the cupboard. Adherence to what you take matters more than the molecule you chose.

That is where Creatine Gummies may make sense for you: they are creatine monohydrate, in the form the evidence supports, in a format some people find easier to keep up with. Each serving of 3 gummies provides 5000 mg of creatine monohydrate and 50 µg of vitamin B12 (2000% of the nutrient reference value). The direction is to chew 3 gummies per day and not to exceed the recommended daily dose. They are intended for adults. They contain polyols, and excessive consumption may have laxative effects. Like any supplement, they do not replace a varied and balanced diet or a healthy lifestyle, and they should be kept out of reach of young children.

Note what we did not say: we are not claiming the gummies work better than any other form, because they do not — they are the same molecule. The difference is in the format and in the likelihood of your taking them every day.

What to check on the label before you buy

A useful label answers four questions. If any of them goes unanswered, that is a sign the manufacturer does not want you to ask it.

• What is the chemical form, written out in full? 'Creatine' on its own is not enough. It should say monohydrate, citrate, malate or whatever it is.
• How much per serving, and what counts as a serving? The number of units per dose and the amount of creatine per dose have to be explicit.
• What other ingredients go in, and in what amount? If vitamins or minerals are added, they should be listed with values.
• What warnings and directions are given? Daily dose, timing, target group and cautions. A serious product does not hide any of this in the small print.

If the label promises something the evidence does not support — superior absorption, no water retention, faster results — that tells you more about the marketing than about the product. And if you cannot find the amount of creatine per serving, do not buy it. Not out of blind suspicion, but because that is the minimum information you need to know what you are taking.

On price, without beating about the bush

Paying more for a fashionable form is paying for a promise the available trials do not confirm. Monohydrate is, according to the systematic review, the cheapest form — and not by chance: it is also the one with the most research behind it. The premium on alternatives does not buy evidence. It buys packaging.

This does not mean the cheapest product on the shelf is automatically the right choice. It means price is not an indicator of quality in this market, and that you should compare labels, not prices per kilogram of marketing.

The honest limit of this page

There are things we cannot tell you, and we would rather name them than fill the space. The stability of creatine in gummy format and the amount per gummy are not covered by the sources underpinning this text. We have no data on third-party testing. We do not address pregnancy, breastfeeding, children or interactions with medicines — if any of those situations applies to you, speak to a healthcare professional before deciding, not to a comparison page.

What you can do next, concretely: take the product you have at home or the one you are thinking of buying and look on the label for the chemical form and the amount per serving. If it says creatine monohydrate and the amount is clear, you are on the right side of the evidence. If it says something else and the price is higher, ask yourself what exactly you are paying for — and if the answer is 'a better name', you already know what to do.
