Supplement Label Review Checklist: 25 Points to Check Before You Print

Why a formal review step matters

A dietary supplement label answers to roughly a dozen separate sections of 21 CFR Part 101, plus the Food Allergen Labeling and Consumer Protection Act — and every one of them is enforceable, whether or not FDA ever personally inspects your specific SKU (21 CFR Part 101, eCFR). FDA's own Dietary Supplement Labeling Guide runs eight chapters just to cover general labeling, identity, net quantity, nutrition labeling, ingredient labeling, claims, new dietary ingredient notification, and miscellaneous requirements.

In practice, label problems are rarely one catastrophic error. They're small formatting drift that compounds over successive redesigns: ingredients reordered after a supplier swap, a disclaimer that got separated from its claim when a designer reflowed the back panel, an allergen that entered the recipe through a new flavor system but never made it into the "Contains" statement. Any one of these is enough to trigger a relabel run, a retailer compliance rejection, an Amazon or TikTok Shop listing suppression, or — in the more serious cases — an FDA warning letter. A structured review before artwork goes to print is what catches it while it's still a five-minute fix instead of a warehouse-sized problem.

Statement of identity & net quantity

The statement of identity is the product name that has to appear on the principal display panel, and federal law specifies exactly what it must contain: the term "dietary supplement," or a version with "dietary" swapped for a description of the ingredient type ("herbal supplement") or the actual ingredient name ("bee pollen supplement") (FDA Labeling Guide, Ch. II; 21 CFR 101.3, 101.1). A brand name is not a legal substitute for the statement of identity, and it can't be given more visual weight on the panel than the statement of identity itself — a common miss when a brand redesign leans hard into logo treatment.

Net quantity of contents must sit on the principal display panel, in the bottom 30% of that panel, expressed in both metric and U.S. customary units, at a minimum type size that scales with the panel's total area (21 CFR 101.105). Small packages get a smaller minimum type size — but there's still a minimum, and a net quantity statement that's technically present but undersized for its panel is a frequent review finding.

The Supplement Facts panel

Every dietary supplement needs a Supplement Facts panel — not a Nutrition Facts panel — unless the product qualifies for the narrow small-business/low-volume exemption and carries zero nutrient content or health claims (21 CFR 101.36(a)-(h)). Serving size has to use the exact term "Serving Size" and reflect the maximum amount recommended per eating occasion (FDA Labeling Guide, Ch. IV).

Vitamin and mineral order on the panel is fixed by regulation, not a design decision — FDA specifies the exact sequence, and it can't be rearranged to feature a marketed ingredient more prominently:

Declared amounts aren't just a formatting exercise — they're a testing standard. Added ingredients must test at 100% or more of the declared amount at time of manufacture, while naturally-occurring ingredients need to test at 80% or more. Pair every label review with a current Certificate of Analysis confirming the panel matches what's actually in the finished product, not just what the formulation sheet says it should contain.

Ingredient statement & allergen declarations

Below the Supplement Facts panel, a separate ingredient statement lists every non-dietary ingredient — binders, fillers, flow agents, coatings — by common or usual name, in descending order of predominance by weight (21 CFR 101.4(a), (g)). This is a distinct list from the Supplement Facts panel itself; dietary ingredients already itemized there don't need to repeat in the ingredient statement.

Since 2004, the Food Allergen Labeling and Consumer Protection Act (FALCPA) has required plain-language declaration of major food allergens, either worked directly into the ingredient list (e.g., "whey (milk)") or called out separately in a "Contains:" statement immediately after it (FDA — FALCPA). The FASTER Act added sesame as the ninth major allergen, effective January 1, 2023 — a gap that still shows up on labels designed before that date and never revisited. The full current list: milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame.

The structure/function disclaimer, word for word

Any structure/function claim, nutrient-deficiency-disease claim, or general well-being claim requires the exact disclaimer specified in 21 CFR 101.93(c) — not a paraphrase, not a shortened version:

Placement matters as much as wording. The regulation requires the disclaimer to be set off in a box and placed in immediate proximity to the claim(s) it covers, or clearly linked by a symbol such as an asterisk, so a reader can't miss which statements it applies to (21 CFR 101.93(d)). A disclaimer that's technically on the label but buried in unrelated fine print, or separated from the claim during a redesign, is one of the most common findings in a label review — the wording was never wrong, the placement just drifted.

Separate from the disclaimer requirement: no supplement label may carry an explicit or implied claim to diagnose, treat, cure, mitigate, or prevent a specific disease without the product being reviewed and approved as a drug (21 U.S.C. § 343(r)(6)). That's a bright line — no disclaimer, no notification filing, and no amount of careful wording makes a disease claim permissible on a supplement label.

Business info, directions, warnings, traceability

The label must show the name and place of business of the manufacturer, packer, or distributor, qualified with "Manufactured for" or "Distributed by" when the listed party didn't physically produce the product (21 CFR 101.5). Directions for use should match the declared serving size — a common inconsistency shows up when marketing copy suggests a different dosing pattern than the panel actually supports.

Warnings and cautions apply wherever the ingredient profile calls for them: iron-containing products, stimulant-containing products, and anything relevant to pregnancy or nursing populations commonly need specific cautionary language. State-level requirements layer on top of federal ones — California's Proposition 65 warning requirement is the one most likely to apply and needs to be checked independently of the federal checklist.

Lot or batch coding and an expiration or best-by date are expected under current Good Manufacturing Practice recordkeeping standards (21 CFR Part 111), and they're the first thing a recall or complaint investigation needs — confirm the code is present, legible, and actually links back to a real batch production record. And if a formulation includes a dietary ingredient not marketed in the U.S. before October 15, 1994, and not generally recognized as safe, a New Dietary Ingredient notification has to be filed with FDA at least 75 days before the product goes to market (21 CFR 190.6) — a label can be flawless and still be attached to a product that was never cleared to launch.

The 25-point checklist at a glance

The companion workbook breaks these requirements into 25 individually tracked checkpoints, each tied to its governing regulation, so a reviewer can move through a label systematically instead of relying on memory:

• Statement of identity, net quantity of contents
• Supplement Facts panel presence, serving size, servings per container
• Mandatory nutrients, vitamin/mineral order, % Daily Value calculation
• Other dietary ingredients footnote, proprietary blend disclosure
• Supplement Facts formatting (boxing, title size, minimum type size)
• Ingredient statement order, major allergen declaration
• Structure/function disclaimer presence and placement, no undisclosed disease claims
• Manufacturer/distributor information, directions for use
• Warnings/cautions, lot code and expiration date
• New Dietary Ingredient notification status, country-of-origin marking, barcode accuracy, label-to-marketing consistency

What should trigger a fresh review

A full 25-point pass isn't only for new SKUs. Re-run it whenever:

• A supplier, ingredient source, or excipient changes — even one that seems unrelated to potency or claims
• Dosage or serving size changes, or the recommended use instructions are revised
• New claim language is added anywhere the product is marketed, not just on the physical label
• The label goes through a design refresh, even a "cosmetic" one — reflowing copy is exactly when disclaimers and required statements get separated or dropped
• The product is introduced to a new retailer or marketplace with its own listing-content requirements

Common mistakes that slip through

• Ingredient order left unchanged after a supplier substitution shifted actual ingredient weights
• Disclaimer text correct but separated from the claim it covers after a layout redesign
• Sesame missing from the "Contains" statement on labels designed before the FASTER Act's 2023 effective date
• Proprietary blend shown without a total blend weight, or with ingredients not in descending order
• Directions for use that imply a dosing pattern the declared serving size doesn't support
• Marketing claims on the website or Amazon listing that have drifted ahead of what's actually printed on the physical label
