Is Creatine Vegan? Where Creatine Really Comes From

Yes, creatine is vegan. The creatine monohydrate in supplements is made in a reactor from non-animal ingredients, and the molecule is the same one your body produces every day. The more useful question is where creatine comes from in the first place: how your body makes it, which foods carry it, why people who eat mostly plants tend to hold smaller stores, and why a tub of vegan creatine is simply creatine, whatever the label says.

Is Creatine Vegan?

Almost all of it, yes. Commercial creatine monohydrate is not extracted from meat; it is a synthetic compound. It is built in a chemical reactor from two non-animal precursors, and the finished molecule is the same creatine you would find in a steak or that your own body makes (more on that below).

So a tub labelled "vegan creatine" is telling you something about the capsule, the flavouring or the factory's certification, not about the creatine. The things worth checking are gelatin capsule shells, which are animal-derived, and the occasional flavoured blend that uses a dairy ingredient. Plain creatine monohydrate powder, or a product in vegetable (HPMC) capsules, is vegan by default.

That is the short answer. The longer one is why a molecule found almost only in animal muscle ends up vegan at all, and for that you need the origin story.

Where Does Creatine Come From in the Body?

Creatine is not something you have to eat. Your body can make a small amount every day, depending on your protein intake, from three amino acids: arginine, glycine and methionine.⊕ The first step happens mostly in the kidneys, where arginine and glycine are combined into a precursor called guanidinoacetate. The second happens mostly in the liver, where methionine donates a methyl group and the result is creatine.⊕ From there it travels in the blood to the tissues that use it most.

The numbers are modest but steady. Margaret and John Brosnan, who have spent decades on creatine metabolism, put a 70 kg adult's daily need at about 2 g, with up to half of that coming from an omnivorous diet and the rest synthesised, so roughly a gram a day made in-house, provided the raw materials are there.⊕ Synthesis runs on amino acids, so it depends on eating enough protein, and not everyone does: in one study of UK adults aged 65 and over, more than a third fell short of the national protein recommendation, and protein carries its own authorised claim for the maintenance of muscle mass.⊕ Around 95 per cent of the body's creatine sits in skeletal muscle,⊕ much of it in a charged form called phosphocreatine. Supplementing adds to what you make: the authorised UK and EU performance claim for creatine applies at a daily intake of 3 g.

Phosphocreatine is the useful bit. In a short, hard effort, a sprint, a heavy lift, the first few seconds of any all-out movement, muscle burns through ATP faster than it can rebuild it from carbohydrate or fat. Phosphocreatine hands its phosphate over to regenerate ATP almost instantly. That mechanism is why the authorised UK and EU health claim for creatine is worded around "successive bursts of short-term, high intensity exercise" rather than anything grander.

Where Does Creatine Come From in Food?

Creatine lives in muscle. That single fact explains everything else in this article. If a food is muscle tissue, it contains creatine. If it is not, it essentially does not.

Raw meat carries a few grams of creatine per kilogram: Harris and colleagues measured roughly 30 mmol per kilo, or about 4 g, in uncooked chicken, beef and rabbit.⊕ Fish is muscle too, and together with red meat it is the other main dietary source.⊕ Cooking lowers those figures, because heat converts some creatine to creatinine, so what reaches your plate is less than the raw number. Add it up and a typical omnivorous diet supplies around a gram of creatine a day,⊕ roughly the same amount the body makes itself. Omnivores run a half-and-half system: half synthesised, half eaten.

Vegetables, grains, pulses, nuts, seeds and fruit contain no meaningful creatine. Nor do eggs or dairy, which are not muscle tissue. Milk carries a trace, which is why the Brosnans note that breastfed infants get some,⊕ and eggs essentially nothing. People often ask how much creatine two eggs contain. As near to none as makes no difference. This is why the creatine question comes up so often for people following a plant-based diet.

So "vegan sources of creatine" and "creatine rich foods for vegetarians" are searches with no good answer, because there are none. If you eat mostly plants, every milligram of creatine in your muscles was made by you. Whether that matters is the next question.

What Does This Mean If You Eat Mostly Plants?

It means your stores tend to be a little lower, and that your body is doing the whole job itself. Neither is a problem.

The research here is consistent. A 2020 systematic review by Kaviani, Shaw and Chilibeck pulled together nine studies and found that vegetarians generally carry lower muscle creatine than omnivores, by around 10 to 15 per cent in the thigh muscle most often biopsied, and lower creatine in blood plasma.⊕ The classic trial is Burke and colleagues in 2003,⊕ which measured muscle creatine in 42 vegetarians and omnivores before and after eight weeks of supplementation alongside weight training. The vegetarians started lower and finished with a larger rise in total muscle creatine.

That pattern holds across the literature: plant-forward eaters begin with less in the tank, and when they add creatine, their muscles take up more of it. What that means for performance is less tidy. In Burke's trial the vegetarians who supplemented also gained more lean tissue and did more work in a muscular endurance test than the omnivores who supplemented. Other, shorter studies in the same review found similar gains in both groups, and the authors describe the performance evidence as mixed.⊕

One UK study turns up in every discussion of this topic, so it belongs here for completeness. Benton and Donohoe at Swansea gave 20 g of creatine or a placebo to 121 young women, 70 of them vegetarian, for five days and saw better performance on a memory task in the vegetarian creatine group only.⊕ The authors themselves called the findings preliminary. It is one short study with a narrow sample, and it should be read as exactly that: an observation, not a promise. What the research says specifically about creatine for women is covered in its own article.

What "lower stores" does not mean also needs saying. Creatine is not an essential nutrient. There is no recognised creatine deficiency in healthy adults, and the body can make enough for normal function unless there is a rare inborn error in one of the synthesis enzymes.⊕ Lifelong vegetarians and vegans are not short of anything. Lower muscle stores are a consequence of where the molecule lives, which is in the foods you have chosen not to eat. The one practical implication is that if you decide to take creatine, you will probably notice the change in your stores more than a meat eater would.

Is Creatine Vegetarian?

Yes, for the same reason it is vegan. The creatine in supplements is synthetic, so it suits vegetarians and vegans alike, with the same caveats about capsule shells.

The vegetarian question deserves its own answer because people sometimes assume eggs and dairy put them in a different position from vegans. For creatine, they do not. Eggs and milk are not muscle tissue, so they contribute very small amounts at most.⊕ A lacto-ovo vegetarian and a vegan sit in the same place here: both rely on what the body makes, both tend to carry lower muscle stores, and both respond to supplementation the same way. That is why the research literature mostly treats "vegetarian" and "vegan" as one group when it comes to creatine.

Pescatarians are the exception. Fish is muscle, so a diet that includes it supplies dietary creatine much as a meat-containing diet does.

How Is Vegan Creatine Made?

Creatine monohydrate is made by reacting sarcosine, usually as its sodium salt, with cyanamide in water. Kreider and colleagues describe the standard industrial process: a sodium sarcosinate solution is brought to around pH 10 and about 80 °C, a cyanamide solution is added and stirred in, the mixture is cooled, and the creatine monohydrate that crystallises out is filtered, washed and dried into the fine powder you see in a tub.⊕

Neither precursor is an animal extract. As the 2020 systematic review puts it, the creatine in most supplements is synthesised from sarcosine and cyanamide and does not contain any animal by-products.⊕ The finished monohydrate is creatine with one molecule of water attached, and it dissociates into plain creatine once you swallow it, the same molecule your kidneys and liver make.

That is why "vegan creatine" is a label rather than a different product. There is no plant-extracted creatine to compare it with, and no animal-extracted creatine on the market either. What you are choosing between is creatine monohydrate from different factories, with different purity standards, in different packaging. Monohydrate versus other forms, purity grades and how to read a label are a topic in their own right and belong in a separate piece.

How Much Creatine, and How?

The number that matters in Europe is 3 g a day. That is the intake at which the authorised UK and EU health claim applies: creatine increases physical performance in successive bursts of short-term, high intensity exercise.⊕ Below that, the claim cannot be made. Above it, the claim does not change. The claim is authorised for foods aimed at adults doing high-intensity exercise, and like every authorised claim it sits on top of a varied, balanced diet and a healthy lifestyle rather than in place of them.

For a plant-forward eater there is no special protocol. The same 3 g daily dose, taken consistently, is what the evidence and the claim are built on. Loading phases, timing around training and whether to take it with food are covered in how to take creatine, so this piece will not repeat them.

Whether to take creatine at all is a personal decision. Plenty of people eating mostly plants are content with the stores their body makes. Plenty of others decide that a daily 3 g of creatine monohydrate is a reasonable, well-studied option to add alongside training. Both are sensible positions. The origin story gives you the understanding to choose, rather than a reason to worry.

Frequently Asked Questions

Is all creatine vegan?

The creatine itself, yes, because commercial creatine monohydrate is synthetic. The product around it may not be: gelatin capsules are animal-derived, and some flavoured blends use dairy ingredients. Plain monohydrate powder or vegetable capsules are the simple choice.

Can you get creatine from vegetarian foods?

No. Creatine is found in muscle tissue, and no plant, egg or dairy food contains a meaningful amount. Vegetarians and vegans rely on what the body synthesises from arginine, glycine and methionine.

Does vegan creatine have different side effects?

No. It is the same molecule as any other creatine monohydrate, so there is nothing specific to a vegan product. Questions about water weight and hair loss are answered in our creatine myths article.

What is vegan creatine made from?

Sarcosine and cyanamide, two non-animal chemical precursors, reacted together and then crystallised and purified into creatine monohydrate. The result is the same molecule your body makes.

Are creatine gummies and capsules vegan?

Often, but check. Gummies may use gelatin or beeswax; capsules may use gelatin shells. Look for pectin-based gummies and HPMC (vegetable) capsules if that matters to you.

Why do vegans have lower creatine stores?

Because dietary creatine comes only from meat and fish. Without that roughly one gram a day from food, muscle stores settle at a lower level. The body makes up part of the difference by synthesising more, and this is not a deficiency.
