Answer
Availability
Commodity ingredient available from multiple producers, with global output concentrated in Chinese fine-chemical clusters plus Alzchem in Germany. A demand surge (US creatine sales up 60.6% year over year) has driven reported spot-price volatility through 2025-2026.

What it is
- The unbranded baseline for the creatine class: no license or trademark program applies; buyers qualify suppliers directly on spec, testing, and provenance. [IR branded-ingredient ecosystem research]
Spec parameters buyers should demand
What to ask for on the certificate of analysis and spec sheet. Identity, quality, and regulatory parameters only. This is not advice about efficacy.
| Parameter | What to ask | Why it matters |
|---|---|---|
| Assay (creatine content) | Request the certificate of analysis and the assay method. Pharmacopeial creatine is defined as not less than 98.0% and not more than 102.0% creatine on the dried basis (USP-NF); confirm the CoA names the method used.[USP-NF Creatine monograph] | With no trademark program to stand behind the material, the assay and its stated method are the primary comparison point across generic suppliers. |
| Identity verification | Confirm the manufacturer runs at least one validated identity test on each incoming lot, as 21 CFR 111.75(a)(1) requires for every dietary ingredient.[21 CFR 111.75(a)(1) — identity test required for each dietary ingredient] | Identity testing is a federal manufacturing requirement and is the control that most protects you when buying unbranded material from multiple suppliers. |
| Synthesis-route impurity limits | Request limits and results for dicyandiamide (DCD), dihydrotriazine (DHT), and creatinine. The referenced specification is creatinine not more than 100 mg/kg, DCD not more than 50 mg/kg, and DHT not detectable.[EFSA Scientific Panel opinion on creatine monohydrate] | These byproducts of the sarcosine-plus-cyanamide route vary between producers; without a brand program to guarantee them, the CoA is your only assurance. |
| Heavy metals | Request lead, arsenic, cadmium, and mercury results with the test method and the limits applied.[USP-NF Creatine monograph] | Heavy-metal control is a baseline quality attribute and matters more when provenance is variable across generic lots. |
| Country and site of manufacture | Request the country and site of manufacture for each lot. Global creatine output is concentrated in Chinese fine-chemical clusters plus one producer in Germany, so provenance can change between lots.[NutraIngredients — Alzchem confronts capacity pressures] | Provenance drives both supply risk and the impurity/heavy-metal profile you should expect; it is a moving target for generic material and belongs on every lot's record. |
QC and testing considerations
- Every dietary ingredient must pass at least one validated identity test before use (21 CFR 111.75(a)(1)). For generic material bought from more than one supplier, run identity testing on each incoming lot, not only at supplier qualification. [21 CFR 111.75(a)(1)]
- Generic creatine is made from sarcosine and cyanamide and can carry dicyandiamide, dihydrotriazine, and creatinine that vary by producer. Ask for a certificate of analysis that reports these byproducts against the accepted limits on every lot. [EFSA Scientific Panel opinion on creatine monohydrate, EFSA Journal 2004;36]
- Creatine converts to creatinine in the presence of water and heat, so the anhydrous powder is the stable form. For liquid or gummy formats, test the finished product for both creatine content and creatinine, not just the incoming raw material. [EFSA Scientific Panel opinion on creatine monohydrate]

A reference list is not claim substantiation. Under the FTC's Health Products Compliance Guidance (December 2022), marketing claims about a finished product require competent and reliable scientific evidence, typically randomized, controlled human clinical testing. Responsibility for substantiating product claims rests with the brand.
