Creatine Label Facts
Creatine monohydrate is the most common single-ingredient labeled form on supplement panels. Creapure is a trademarked designation for creatine monohydrate manufactured by Germany's AlzChem under that company's own purity-testing program — a sourcing/purity label distinction, not a different compound. "Creatine blends" or "formulas" combine monohydrate with other forms inside one blend line, which reintroduces the same proprietary-blend opacity covered elsewhere on this site.
The one thing to know: Creatine monohydrate is the most-labeled, most-studied form on supplement panels, and Creapure is a specific trademarked source (creatine monohydrate manufactured by Germany's AlzChem under its own purity-testing program) rather than a different compound — a label distinction about manufacturing source and purity testing, not about the creatine molecule itself. Many labeled 'creatine blends' or 'creatine formulas' combine monohydrate with other compounds (HCl, ethyl ester, buffered forms) inside a single blend line, which reintroduces the same proprietary-blend opacity described above: the label shows what's in the blend but not each ingredient's individual dosed amount.
Reading the label: monohydrate vs other forms
| Label term | What it denotes |
|---|---|
| Creatine monohydrate | The standard single-ingredient labeled form; most commonly studied and most widely available. |
| Creapure | A trademark for creatine monohydrate manufactured by AlzChem (Germany) under its own licensed purity-testing program — a sourcing/purity claim, not a different molecule. |
| Creatine HCl | A different creatine salt form (hydrochloride) than monohydrate, labeled as a distinct ingredient. |
| Buffered creatine ("Kre-Alkalyn") | A pH-buffered creatine monohydrate variant, labeled and trademarked distinctly from standard monohydrate. |
| Creatine blend / formula | Combines two or more of the above inside a single blend line — check whether individual amounts are disclosed or only a combined total. |
Why "blend" labeling matters here specifically
If a product lists its creatine forms inside a "blend" or "proprietary blend" line, the same disclosure rule applies as any other supplement blend: ingredients are shown in descending order by weight, but the individual gram amount of each specific form is not required to be broken out. See Do Proprietary Blends Hide Anything? for the full rule.

Labels the specific Creapure trademark, which denotes creatine monohydrate manufactured by AlzChem under that licensing and purity-testing program — a sourcing/purity label distinction, not a different compound.
Best for: Comparing single-ingredient creatine monohydrate label claims against blended 'creatine formula' products
Watch out: Creapure is a manufacturing/purity license for creatine MONOHYDRATE specifically — it says nothing about products blending creatine with other ingredients, which is a separate label category entirely.

Creatine monohydrate is the most common single-ingredient form on supplement labels. Other labeled forms (HCl, ethyl ester, buffered/'kre-alkalyn', and blended 'creatine formulas') are distinct label categories combining monohydrate with other compounds or using an entirely different creatine salt — a label and formulation distinction, not a claim we are evaluating for effectiveness.
Creapure is a trademarked designation for creatine monohydrate manufactured by Germany's AlzChem under that company's own purity-testing and manufacturing program. It denotes a specific manufacturing source and purity-testing claim for creatine monohydrate — it is not a different compound from creatine monohydrate generally.
Not necessarily — if a product lists its creatine forms inside a 'blend' or 'proprietary blend' line, the same proprietary-blend labeling rules apply: ingredients are shown in descending order by weight, but the individual gram amount of each form is not required to be disclosed separately.
