"Is creatine FDA approved?" draws about 2,400 searches a month, up threefold in a year, with "is creatine a drug" and "is creatine a stimulant" close behind. The short answer is no, and the reason is not that creatine failed a review: the US law that governs supplements gives FDA no approval step to pass. What FDA has done is narrower, and the labels on the shelf describe it in ways worth reading closely. This page sets out the law, the one creatine file FDA has closed, and what 150 creatine labels say about FDA. It reports the regulatory record; it does not advise anyone whether to take creatine (how we work).
The short answer: creatine is a dietary supplement. FDA does not approve supplements before sale. In 2020 FDA reviewed — and did not question — a company's conclusion that 1 g of creatine per serving is safe to add to ordinary foods and drinks. No creatine product carries an FDA approval, and none of the 150 labels read for this page claims one.
What the law says
Creatine is sold in the US under the Dietary Supplement Health and Education Act of 1994 (DSHEA). Three pieces of the law decide the question:
- The definition. A dietary supplement is a product intended to supplement the diet that contains a "dietary ingredient", a list that includes "an amino acid" and "a concentrate, metabolite, constituent, extract, or combination" of one (21 U.S.C. 321(ff)). Creatine is made in the body from three amino acids (the chemistry is on how creatine is made), and it is sold as a supplement on that footing.
- No pre-market approval. FDA's own questions-and-answers page states plainly that "Under DSHEA, FDA does not have the authority to approve dietary supplements before they are marketed" (FDA, current as of 2026-08-27). The maker is responsible for safety and for the truth of its label; FDA acts after a product is on sale.
- The disclaimer. A supplement may say how an ingredient affects the body's structure or function — "supports muscle performance" — but not that it treats a disease. Any such statement must carry, in bold, the words "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease" (21 U.S.C. 343(r)(6); text fixed in 21 CFR 101.93(c)). The sentence most creatine buyers have read on a tub is the law telling them FDA has not reviewed the claim above it.
So "is creatine FDA approved?" has a structural answer: no supplement is. The same is true of whey protein, fish oil and multivitamins.
The one file FDA has closed on creatine
The exception is not a supplement review at all. A company that wants to add an ingredient to ordinary food — a sports drink, a protein bar — can notify FDA that the use is "generally recognised as safe" (GRAS) and send its evidence.
| GRN 931 | |
|---|---|
| Substance | Creatine monohydrate |
| Notifier | AlzChem Trostberg GmbH, Germany (the maker of the Creapure brand, described on Creapure explained) |
| Intended use | Energy drinks, protein bars and powders, milk shakes, meal-replacement bars and powders, meat analogues and dry powdered drink mixes |
| Level | 1.2 g creatine monohydrate per serving, equivalent to 1.0 g creatine |
| Basis | Scientific procedures |
| FDA response | "FDA has no questions" — closed 12 November 2020; corrected letter 3 December 2020 |
Source: FDA GRAS Notice Inventory, GRN 931, read 2026-10-17. It is the only creatine entry the inventory returns for a "creatine" search.
Three things about this file are easy to misread:
- "No questions" is not approval. The letter records that FDA did not question the notifier's own conclusion, for the stated uses and level. It does not approve a brand, a product or a claim.
- The level is a food level, not a supplement amount. The notice covers 1 g of creatine per serving of food. Supplements are a separate category under DSHEA and were not the subject of the notice; the 3–5 g a day studied in trials is discussed on how much creatine.
- It explains the creatine drinks. Ready-to-drink creatine beverages and creatine-fortified bars sold as foods sit under this route rather than under DSHEA. The trouble with keeping creatine stable in a drink is on liquid creatine.
What 150 labels say about FDA
The NIH Office of Dietary Supplements' label database holds 772 on-market labels listing creatine as an ingredient. MuscleLedger read a random sample of 150 labels from 79 brands on 2026-10-17 — single-ingredient powders, pre-workout formulas, capsules and blends — and searched every label statement for FDA.
| What the label says | Labels (of 150) |
|---|---|
| The standard "not been evaluated by the Food and Drug Administration" disclaimer | 135 |
| An FDA-registered, FDA-inspected, FDA-compliant or "regulated by the FDA" facility | 20 |
| A cGMP or "good manufacturing practice" statement | 54 |
| An NSF mark or NSF wording | 16 |
| "FDA approved" | 0 |
Fifteen labels have no disclaimer in the database's transcription. The disclaimer is required only where a label makes a structure-function statement, and the database records what its staff transcribed; MuscleLedger did not check those 15 packs.
The 20 facility statements are the ones a buyer most often reads as approval. Typical wordings: "Made in an FDA Registered Facility", "Manufactured in a GMP & FDA inspected facility", "Manufactured … in a FDA-compliant facility", and one maker's "inspected and regulated by the FDA". Each is about the building. Supplement facilities must register with FDA under the Bioterrorism Act of 2002, as FDA's questions-and-answers page explains, and FDA can inspect them against its manufacturing rules. None of that is a review of what is in the tub or of what the label claims.
Third-party testing is a separate system run by private certifiers. How the NSF Certified for Sport register works, and which creatine products are on it, is on NSF-certified creatine.
Is creatine a drug?
Not in US law. A product's category follows how it is marketed: a substance sold to supplement the diet, with structure-function wording and the disclaimer, is a supplement; the same substance sold to treat a disease would be an unapproved drug. Creatine needs no prescription and is not on any US controlled-substance schedule; the difference from anabolic steroids, which are Schedule III, is set out on is creatine a steroid.
Creatine has been studied in disease trials — in muscular dystrophies, neurodegenerative disease and the inherited creatine-synthesis disorders — but none has led to an approved creatine medicine. On 2026-10-17 FDA's drug-application database (Drugs@FDA, via openFDA) returned no application with creatine as an active ingredient. Its drug-listing directory (NDC) returned four listings that include creatine, all marked "unapproved homeopathic" — multi-ingredient homeopathic products, not creatine medicines. The disease trials are summarised on creatine and medical conditions.
Is creatine a stimulant?
No. Creatine is stored in muscle as phosphocreatine and used to regenerate ATP during short, hard efforts; it does not act on the brain's arousal systems the way caffeine does. What confuses the question is the shelf: 273 of the 772 on-market creatine labels (35%) in the NIH database also list caffeine, and 108 of those 273 have pre-workout, energy, pump or nitric-oxide wording in the product name. A buyer who feels "wired" after a creatine product is usually feeling the caffeine. The difference between a creatine powder and a pre-workout, scoop by scoop, is on creatine vs pre-workout; how the two molecules interact is on creatine and caffeine.
How other regulators treat it
The US approach — sell first, police afterwards — is not universal.
- European Union. Creatine is permitted in food supplements, and the EU authorises exactly one health claim for it: "Creatine increases physical performance in successive bursts of short-term, high intensity exercise." The claim may be used only on food that provides a daily intake of 3 g of creatine, with that intake stated to the consumer, and only for foods aimed at adults doing high-intensity exercise (Regulation (EU) No 432/2012, annex). An authorised claim is not a product approval either, but it is a reviewed statement — something US law does not provide for structure-function wording.
- Sport. Creatine is not on WADA's Prohibited List, and the NCAA's banned-drug classes do not name it (both checked on is creatine a steroid). College rules on what a school may supply are separate: in 2000 the NCAA adopted Bylaw 16.5.2.2, barring member schools from distributing "muscle-building supplements", after schools had been handing out creatine, according to the NCAA News of 9 April 2001. The current text of that rule was not read for this page.
What is not established
- Whether any specific creatine product contains what its label says. Neither the DSHEA framework nor GRN 931 tests products; contamination and label-accuracy studies are discussed on is creatine a steroid and NSF-certified creatine.
- Whether the 20 "FDA registered" facilities were inspected recently, or with what result. Registration status was not checked facility by facility.
- The current NCAA bylaw wording on what schools may supply.
