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 (beta-alanine content) | Request the certificate of analysis and the assay method. Beta-alanine is an official USP article (USP publishes a beta-Alanine Reference Standard); ask that the CoA state the assay result and the pharmacopeial or validated method used.[USP beta-Alanine Reference Standard] | The assay is the identity-and-strength figure a spec sheet rests on, and a named pharmacopeial method makes results comparable across suppliers. |
| Identity verification | Confirm the manufacturer runs at least one validated identity test on each incoming lot (for example infrared or HPLC), 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, not an optional step; a certificate that names the identity method is the record your own quality file needs. |
| US regulatory footing (NDI / GRAS) | Ask whether the beta-alanine source carries an FDA New Dietary Ingredient (NDI) notification and a documented GRAS determination, and request the paperwork. CarnoSyn is marketed as the beta-alanine holding NDI status and a self-affirmed GRAS determination.[carnosyn.com — 'The only beta-alanine with NDI and self-affirmed GRAS status'] | NDI and GRAS documentation records the ingredient's US regulatory standing and belongs in the due-diligence file for any branded ingredient. |
| Heavy metals | Request lead, arsenic, cadmium, and mercury results with the test method and the limits applied.[21 CFR Part 111 — cGMP for dietary supplements] | Heavy-metal control is a baseline quality attribute for any bulk ingredient and part of a complete certificate of analysis under 21 CFR Part 111. |
QC and testing considerations
- Every dietary ingredient must pass at least one validated identity test before use (21 CFR 111.75(a)(1)). Confirm your manufacturer runs identity testing on each incoming lot, not only at supplier qualification. [21 CFR 111.75(a)(1)]
- Beta-alanine reached the US market through a New Dietary Ingredient pathway; ask the supplier for the NDI notification and GRAS documentation on file so your own regulatory record is complete. [carnosyn.com — NDI + self-affirmed GRAS status]
- For sports and team-channel products, ask whether the beta-alanine carries a banned-substance certification (for example Informed Sport or NSF Certified for Sport) and request the current certificate for the lot you are buying. [carnosyn.com — states manufacture under GMP certification and banned-substance-free material]

Reference list
- USP beta-Alanine Reference Standard (compendial identity/assay standard, CAS 107-95-9) Pharmacopeia
- 21 CFR Part 111 — Current Good Manufacturing Practice for dietary supplements (identity testing at 111.75) Regulatory

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.
