How to label a supplement to sell on Amazon

Here's the whole picture, label side first, then the documentation.

Where this information comes from

Amazon publishes its supplement policies inside Seller Central, behind a login. We can't read it and neither can Google, so anyone presenting Amazon's supplement policy as a directly quoted public document is either a seller with an account or is guessing.

What follows on the cGMP requirement comes from trade press and industry association reporting: Nutraceuticals World (December 19, 2025), the American Herbal Products Association (December 18, 2025), NutraIngredients (December 22, 2025), and Certified Laboratories (January 2026). Reporting differs on some details, and Amazon changes seller policy without notice. Check the current requirement in your own Seller Central account before you spend money on an audit. The regulatory sections cited below are different — those are primary sources you can read yourself.

Amazon's cGMP verification requirement

Reported in December 2025: all dietary supplement sellers must provide verification, from an Amazon-approved third-party Testing, Inspection and Certification (TIC) entity, that the product was manufactured in a facility compliant with current Good Manufacturing Practice. The underlying federal rule is 21 CFR Part 111, FDA's cGMP regulation for manufacturing, packaging, labeling and holding dietary supplements.

The rollout is phased. Amazon is contacting affected sellers in waves rather than switching everything off at once. Sellers who get contacted have 90 days to initiate a documentation request with a participating TIC entity. Note the verb: initiate. You are not expected to complete a full audit in 90 days, but you are expected to have started.

Accepted programs, as reported, include NSF/ANSI 455-2, USP GMP, Eurofins GMP, UL GMP, SGS, Intertek, SAI Global, TGA, the SQF Dietary Supplements Food Safety Code, GFSI-benchmarked schemes and SSCI. AHPA's notice described the list as illustrative rather than closed, so a scheme not named here isn't automatically out.

What is reported as not accepted:

• private audits
• first-party audits
• consulting audits
• FDA inspections

That last one catches people. An FDA inspection of your contract manufacturer, even a clean one, is not third-party certification in Amazon's sense. Neither is your manufacturer's internal audit, nor the report from the consultant who helped them prepare.

A fast-track route exists. Reporting describes a Compliance Fast-Track option under which Amazon collects certification materials directly from participating certifying organizations — named as BSCG, Clean Label Project, GRMA, Informed, NSF and USP — rather than from you. If your manufacturer already holds one of those, ask whether the fast-track covers it before you commission anything new.

This sits on top of an existing testing requirement. Since 2024 Amazon has required third-party product testing for supplements in the sexual enhancement, weight management, bodybuilding, sports nutrition and joint health categories. The cGMP facility verification is separate and additional, and reporting indicates the fast-track does not cover that category-specific product testing.

Practical read for a small brand: the certification is almost always your contract manufacturer's to hold, not yours. Ask them in writing which accepted scheme they're certified under and whether they'll share the certificate. If the answer is "we follow cGMP" with no certificate from a named third party, you have a problem that costs more than a label.

The label itself

None of the documentation above helps if the panel is wrong. Supplements have their own labeling regulation and it is not 21 CFR 101.9.

Supplement Facts panel, 21 CFR 101.36. The "Supplement Facts" heading set in type larger than all other print in the panel per 101.36(e)(1). Serving size derived from the maximum amount your label recommends per eating occasion, not a RACC. Nutrients present at zero omitted, not written as zero. Dietary ingredients with no established Daily Value carrying a symbol that points to a "Daily Value not established" footnote below the last heavy bar, per 101.36(b)(2)(iii)(F). Proprietary blends declared as one total weight with components in descending order by weight, per 101.36(c). Botanicals naming the part of the plant, per 101.36(d)(1). Full detail in Supplement Facts panel requirements.

Statement of identity. The words "dietary supplement" (or a variant like "herbal supplement") have to appear on the front. It's part of the statutory definition at 21 U.S.C. 321(ff)(2)(C), not a nicety. If you're not sure your product is a supplement at all, sort that out first: Supplement Facts vs Nutrition Facts.

Ingredient list, 21 CFR 101.4(g). Immediately below the panel, or contiguous and to its right. Where ingredient sources are already named inside the panel, the outside list is headed "Other ingredients." Capsule shell, magnesium stearate, silica, rice flour go outside the panel, and putting them inside is one of the most common self-built-label errors.

Allergens. The 9 major allergens — milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame — must be declared, either parenthetically in the ingredient list or in a "Contains" statement. Sesame has been a major allergen since January 1, 2023 under the FASTER Act, and tree nuts, fish and shellfish must name the species. See FDA's food allergen guidance. Then make your Amazon allergen attributes match the label exactly; a mismatch is its own flag.

Manufacturer, packer or distributor name and place of business, and the net quantity of contents on the principal display panel.

Images that show all of it. Front and back of the package, plus close-ups of the Supplement Facts panel, the full "Other ingredients" list, the allergen declaration, the manufacturer information and the net quantity. Straight on, even light, no glare, no crop cutting off the footnote. The standard a reviewer applies is whether they can read every value without zooming past the pixel limit.

Claims are enforced across the whole listing

Amazon reads the title, the bullets, the description, the A+ content and the text inside your images. A claim in any of them is treated as labeling.

Disease claims are the hard stop. "Lowers blood pressure," "reverses type 2 diabetes," "fights inflammation," "boosts immunity against colds." These aren't merely against Amazon policy. Under the FD&C Act they make your product an unapproved new drug, and Amazon enforces because it inherits the liability.

Structure/function claims are permitted, with strings. "Supports immune health," "helps maintain cholesterol levels already in the normal range." These require the verbatim disclaimer from 21 CFR 101.93 — "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." — plus a notification to FDA within 30 days of first marketing. Full breakdown, including the implied-disease-claim traps that catch product names, images, study citations and reprinted testimonials, in structure/function claims and the FDA disclaimer.

Nutrient content claims have fixed definitions. "High in vitamin C" means 20% or more of the DV per serving. If your product doesn't meet the number, don't use the word.

The failure mode here is specific to supplements: brands clean the printed label, then leave a disease claim in an A+ content module or a review quote they pasted into a bullet. Audit the listing, not the package.

How enforcement escalates

The general pattern sellers report runs:

Detail page suppression → listing removal → account warning → account suspension.

Amazon does not publish this as a fixed sequence, and treating it as one is a mistake. Each stage is a real, documented enforcement action, but Amazon can skip stages. For a severe violation — a disease claim on a supplement is the standard example — it can go straight to removal with no suppression stage first. Missing cGMP documentation after the 90-day window has its own path.

What each stage costs: suppression makes the ASIN unbuyable and is cheap to reverse. Removal deletes the ASIN and you rebuild rank from zero. An account warning attaches to the seller account rather than the product and follows you across every listing you own. Suspension holds your disbursements.

The trap is patching. Re-uploading a sharper photo of a non-compliant panel is a repeat violation, and repeat violations move you up. Fix the panel once, correctly, and images stop being the issue. Note too that Amazon's enforcement sits downstream of federal law: Amazon reinstating your listing does not mean your label is compliant, and FDA is not bound by Amazon's decisions.

Pre-launch checklist

Work this before you list, not after you're suppressed.
