Most label problems are not design problems. They are content problems discovered after the artwork has already been printed, which is the most expensive possible moment to find them. This checklist covers what a US dietary supplement label has to carry, the five items that are most often wrong, and the sequence that prevents a reprint.
The seven elements of a US supplement label
- Statement of identity — what the product is, in a form the buyer recognises ("Dietary Supplement", "Gummies", "Capsules").
- Net quantity of contents — in the correct unit for the form: count for solids, weight or volume for powders and liquids.
- Supplement Facts panel — the nutrition-style panel described in 21 CFR Part 101, with serving size, amounts per serving and the ingredient list.
- Other ingredients — everything that is not an active, listed in descending order of weight.
- Allergen declaration — any major food allergen present, including when it appears in an "other ingredient" or as a processing aid that carries over.
- Name and place of business — the responsible firm, with a city, state and postcode. A distributor's address is acceptable only if it is clearly labelled as such.
- Structure/function disclaimer — where a claim is made, the statement required by 21 CFR 101.91.
Supplement Facts: the part that must match production
The panel is a contract with the batch record. Serving size on the label has to equal the fill weight or capsule count in production, or the declared "amount per serving" is wrong before anything is manufactured. This single mismatch causes more relabelling than any other error.
Two more details buyers frequently miss. First, an ingredient with no established reference intake still needs a declared amount — a blank percentage is not a substitute. Second, a proprietary blend may list total blend weight with components beneath it, but the components must then appear in descending order and cannot carry individual amounts.
Claims: what needs the disclaimer, and what cannot be said at all
A structure/function claim describes how a nutrient affects the body — it does not need pre-approval, but it does require the disclaimer that the statement has not been evaluated by the FDA and that the product is not intended to diagnose, treat, cure or prevent any disease. The wording is specified in 21 CFR 101.91 and is not a place for creative paraphrase.
A disease claim is a different category entirely: naming a condition, or implying the product treats, prevents or reduces the risk of one, moves the product outside supplement labelling. The same applies to testimonials and front-panel copy, which are read as claims too. If your marketing team wants "supports healthy blood sugar", that is a claim discussion, not a design discussion — settle it before artwork.
Allergens and "may contain"
Major allergens must be declared in plain language, either in the ingredient list or in a "Contains" statement immediately after it. Check the finished formula, not the active ingredients: gelatine, lecithin, milk-derived carriers and sesame are the ones that slip through because nobody looked at the excipient list.
Precautionary "may contain" wording should reflect a real, assessed cross-contact risk. Printing it on everything as insurance weakens the declaration and invites questions during a customer audit.
The five errors that cause reprints
- Serving size does not match the batch record — two gummies on the panel, one gummy in production.
- Capsule count and net quantity disagree — "60 capsules" on the front, 60-count panel computed from a 62-capsule fill.
- Other ingredients missing an excipient — usually the one added late in development.
- Claim on the front panel, disclaimer only on the back — the claim needs to be tied to the disclaimer, not separated from it.
- Wrong market's rules on a multi-market label — a US panel and an EU nutrition declaration are not interchangeable, and one artwork rarely serves both without a second version.
Non-US markets need a second version, not a footnote
The EU requires a nutrition declaration in a different format, plus novel food status checks for ingredients without a history of consumption. The UK largely mirrors the EU structure. Australia and New Zealand use their own permitted-claims framework. Treat each as a separate artwork with its own approval, and budget the print run accordingly.
An approval sequence that avoids reprints
Lock the formula first, then the serving size, then the panel, then the claims, and only then the visual design. Approve a text-only proof with the panel at final size before any colour work begins — at that stage a change costs an email, and after plating it costs a print run.
How Haiyue Shengda handles artwork
We draft the Supplement Facts panel from the approved formula and fill weight, flag allergen and claim issues before design starts, and send a text proof for sign-off ahead of the print-ready file. Trial orders start at 100 units, samples ship in 3–5 days, and production follows within 7 days. See our quality and compliance page or contact us with your target market and formula — we reply within one hour.
