"Where does creatine come from?" and its relatives — is creatine natural, how is it made, is there organic creatine — draw about 9,500 searches a month. The answers that rank tend to say creatine is "found in meat" and stop there, which is true of the molecule and not of the powder in a tub. This page traces supplement creatine to the primary documents: the patent that describes how it is manufactured, the biochemistry of how the body makes its own, and the federal rules behind the words "natural" and "organic" on a label. It reports; it does not suggest a product (how we work).
The short answer: supplement creatine is made in a chemical plant, by reacting sarcosinate (a salt of the amino acid sarcosine) with cyanamide, then crystallising the product as creatine monohydrate. No animal tissue is involved. The body separately makes its own creatine from three amino acids, and diet supplies the rest.
The factory route, from the patent
The most detailed public description of commercial creatine manufacture is US patent 5,719,319, "Process for the preparation of creatine or creatine monohydrate", filed by SKW Trostberg AG with a priority date of 18 July 1995 and now held by Alzchem Trostberg GmbH, the maker of Creapure (Google Patents, US5719319A, read 2026-10-14).
What it describes:
| Step | From the patent |
|---|---|
| Starting materials | cyanamide and sodium or potassium sarcosinate, as a technical-grade water solution of 35–40% strength and 85–90% purity |
| Reaction | in water, or water with an organic solvent, at 20 to 150°C and pH 7.0 to 14.0 |
| Product | creatine crystallises out; filtered, washed and dried as creatine or creatine monohydrate |
| Yield | 60 to 90% by weight, purity "up to 100%" |
| Worked example | 1,875 g of pure creatine monohydrate from a potassium sarcosinate batch, 75.3% of theory |
The patent's own background explains why chemists went this way. Creatine "can be obtained from biological material, for example meat waste", which it calls "technically very laborious" and "questionable for hygienic reasons". The basic chemistry is old: the patent cites the synthesis of creatine from sarcosine and cyanamide to Strecker in 1868 and Volhard in 1869, and states that the drawback of that classic route was cost — sarcosine itself is "a very expensive starting material". The 1995 invention's point was to start from cheap technical sarcosinate solutions instead and still reach a pure product.
Creatine monohydrate is the crystal that comes out of water: one molecule of water for each creatine molecule, which is why about 88% of its weight is creatine. Other salts and esters start from the same creatine; they are compared on types of creatine. One maker's purity claims, and the by-products it names, are read on Creapure explained.
How the body makes its own
Creatine is not an essential nutrient; the body builds it in two enzyme steps, mainly in the kidneys and liver (Wyss and Kaddurah-Daouk, Physiol Rev 2000, PMID 10893433):
- Arginine + glycine → guanidinoacetate, by the enzyme arginine:glycine amidinotransferase (AGAT), mostly in the kidney.
- Guanidinoacetate → creatine, by guanidinoacetate N-methyltransferase (GAMT), mostly in the liver, using a methyl group carried by S-adenosylmethionine, which comes from the amino acid methionine.
The creatine then travels in the blood and is pumped into muscle and brain by a dedicated transporter. Roughly 1 to 2% of the body's creatine turns into creatinine each day and is excreted, so it is replaced continuously — about half by the body's own synthesis and half from food in someone who eats meat and fish; the turnover figures and their sources are on what is creatine. Rare inherited defects in AGAT, GAMT or the transporter cause creatine deficiency syndromes, which is where creatine is used as a medical treatment.
So there are two meanings of "where creatine comes from": the molecule in a person's muscles was built by their own kidneys and liver or eaten in meat; the molecule in a tub was built in a reactor. They are the same molecule.
Food sources, briefly
Uncooked beef or salmon carries roughly 1 to 2 g of creatine per pound, by the ISSN's figure. The table by food, and why vegetarians start with lower muscle stores, are on foods high in creatine and creatine for vegetarians and vegans.
What "natural", "vegan" and "organic" mean on a creatine label
Natural. The creatine molecule occurs in nature, but supplement creatine is synthesised. The FDA has never issued a formal definition of "natural"; its longstanding policy for food is that nothing artificial or synthetic has been added that would not normally be expected in the food, and the agency says that policy was not meant to address production methods (FDA, use of the term natural, read 2026-10-14). Searches for "is creatine natural" usually mean either the molecule or the way it was made; the honest answer depends on which.
Vegan. Because the industrial route uses no animal material, creatine monohydrate itself is generally vegan, and some makers state so. A finished product can still contain gelatin capsules or other animal-derived ingredients; that is a label check, not a property of creatine.
Organic. Under the US National Organic Program, a product sold as "organic" or "made with organic" ingredients must be made without synthetic substances except those specifically allowed (7 CFR 205.105), and the allowed non-agricultural substances in processed products are listed in 7 CFR 205.605. Creatine is not on that list (read 2026-10-14). On our reading of the text, that leaves no route for synthesised creatine to carry an organic claim; this is a reading of the regulation, not a ruling, and a certifier makes the actual determination.
The labels agree. In the US government's supplement label register (the NIH Dietary Supplement Label Database), 772 on-market labels list creatine. We read all 22 that mention the word "organic":
| Where "organic" appears (22 creatine labels) | Labels |
|---|---|
| Calls the creatine itself organic | 0 |
| Carries a USDA Organic or "certified organic" statement | 0 |
| Another ingredient (organic caffeine, cane sugar, grains, beet root, selenium) or brand copy | 13 |
| The chemistry phrase "nitrogenous organic acid" | 1 |
| The word sits in a database field we could not tie to an ingredient | 8 |
"Organic creatine" is still searched about 1,700 times a month. The products behind those searches use the word in marketing, but none of the creatine labels in the federal register makes the claim.
What this page cannot tell you
- A patent describes a claimed process, not what any particular factory runs today. Plants in other countries may use variants; their processes are not public.
- The NIH label register holds many but not all products sold in the US, and its records are the makers' own text.
- The organic paragraph is our reading of the regulation text, not legal advice or a certifier's decision.
- Nothing here suggests a product or an amount. How creatine is taken in practice, and what labels direct, is on how labels and the ISSN say to take creatine.
