An FDA supplement label requirements checklist is a structured set of mandatory label elements and formatting rules that dietary supplement manufacturers must follow under 21 CFR Part 101 and DSHEA to achieve regulatory compliance. Missing even one required element — an allergen declaration, a DSHEA disclaimer, or a domestic adverse-event contact — can trigger an FDA warning letter and pull a product from market. This guide covers every mandatory component, from the Supplement Facts panel to structure/function claim disclaimers, so your label clears FDA scrutiny before it reaches a printer.
1. The FDA supplement label requirements checklist: nine mandatory elements
Every dietary supplement label sold in the United States must carry nine core elements. Think of these as the non-negotiable floor before any formatting or claims work begins.
The nine required elements at a glance:
| Label Element | Key Requirement |
|---|---|
| Statement of identity | Must include the term "dietary supplement" or a specific descriptor (e.g., "herbal supplement") |
| Net quantity of contents | Expressed in both U.S. customary and metric units |
| Supplement Facts panel | Formatted per 21 CFR 101.36 with serving size, ingredients, and %DV |
| Ingredient list | All non-dietary ingredients in descending order by weight |
| Manufacturer/distributor info | Name, address, and qualification phrase ("Manufactured by," "Distributed by") |
| Domestic adverse-event contact | U.S. address or phone number per the Consumer Protection Act |
| Allergen declarations | All nine major allergens including sesame per FALCPA and FASTER Act |
| Country of origin | Required for imported ingredients under U.S. Customs rules |
| Lot or batch code | Required for traceability and recall management |
Each of these elements has specific placement and formatting rules. The statement of identity must appear on the principal display panel. Net quantity must appear in the lower 30% of that same panel. Getting placement wrong is as problematic as omitting the element entirely.

2. How to correctly format the Supplement Facts panel
The Supplement Facts panel is the most format-sensitive element on any dietary supplement label. FDA inspects math accuracy, proprietary blend disclosures, and footnotes closely during review, which means a single arithmetic error in a serving-size calculation can invalidate the entire panel.
The panel must open with the bold title "Supplement Facts" inside a defined box. Serving size appears directly below in household measures (e.g., "2 capsules") followed by the number of servings per container. Every dietary ingredient must be listed with its quantitative amount per serving. Where an FDA-established Daily Value exists, the percentage must appear in a "%DV" column. Ingredients without an established Daily Value carry a dagger symbol (†) keyed to a footnote stating "Daily Value not established."
Proprietary blends require special handling. The blend must be listed by its total weight, followed by each component ingredient in descending order by weight. Individual amounts within the blend do not need to be disclosed, but the total blend weight is mandatory. Many manufacturers incorrectly omit the total weight or list components alphabetically rather than by weight.
| Common panel error | Correct approach |
|---|---|
| Serving size not in household measures | Use "2 capsules" not "1.2 g" alone |
| Missing %DV for nutrients with established values | Add %DV column for vitamins, minerals |
| Proprietary blend total weight omitted | State total blend weight before listing components |
| Non-dietary ingredients inside the box | Move excipients below the panel box |
| Font below minimum size | Use at least 6-point type; 8-point preferred |
Non-dietary ingredients — fillers, binders, capsule shells, and flow agents — must appear below the Supplement Facts box under a separate "Other Ingredients" heading. Placing them inside the panel is a common labeling error that FDA flags consistently.
Pro Tip: Treat the Supplement Facts panel as a controlled document with version numbers. Every formula change must trigger a formal panel update reviewed against the master formula record before any artwork is approved.
3. Structure/function claims and the DSHEA disclaimer
A structure/function claim is any statement asserting that a dietary ingredient affects the structure or function of the human body, such as "supports healthy immune response" or "promotes joint flexibility." These claims are permitted under 21 CFR 101.93 but carry strict labeling obligations that many manufacturers underestimate.
The DSHEA disclaimer text must be exact with no paraphrasing permitted. The required wording is: "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." Shortening it to "FDA not evaluated" or rewording it in any way constitutes noncompliance.
Placement rules add another layer of complexity. The disclaimer must appear adjacent to the structure/function claim on every panel where that claim appears. It must be set off with a symbol (typically an asterisk) that connects the claim to the disclaimer text. FDA currently exercises enforcement discretion on multi-panel disclaimer placement while it considers formal rulemaking, but all other disclaimer requirements remain fully active.
Manufacturers must notify FDA within 30 days after first marketing a product bearing a new structure/function claim. The notification must include the exact claim text, the ingredient it relates to, and the brand name. FDA does not approve the claim; it simply receives the notification. Failure to file does not make the claim illegal on its face, but it eliminates a key compliance defense if FDA later challenges the label.
Pro Tip: Map every structure/function claim on your label to its corresponding disclaimer placement during the artwork proof stage. Regulatory and marketing teams must review this together. A single uncoupled claim on a side panel is enough to generate a warning letter.
4. Allergen declarations: beyond the active blend
Allergen labeling for dietary supplements follows the Food Allergen Labeling and Consumer Protection Act (FALCPA), updated by the FASTER Act to add sesame as the ninth major allergen. The nine major allergens now covered are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame.
Allergen declarations must appear either as a "Contains" statement immediately after the ingredient list or as parenthetical common names within the ingredient list itself. Both formats are acceptable; mixing them on the same label is not.
The most overlooked allergen risk in supplement labeling comes not from the active blend but from capsule shells and processing aids. Noncompliance often arises from missing allergen declarations related to capsule shells or processing aids not listed as active ingredients. A gelatin capsule derived from fish, a magnesium stearate sourced from a facility that processes tree nuts, or a maltodextrin carrier made from wheat can all introduce undeclared allergens. Cross-walking every ingredient against supplier Certificates of Analysis (COAs) and specification sheets is the only reliable way to catch these exposures before printing.
Additional compliance checks for allergens:
- Obtain allergen statements from every ingredient supplier, not just primary actives
- Verify capsule shell material and its allergen status in writing from the capsule manufacturer
- Review processing aid allergen status even when aids are not declared on the label
- Update allergen declarations whenever a supplier changes their manufacturing site or process
- Confirm sesame status for all excipients, since sesame oil is used in some softgel formulations
5. Domestic adverse-event contact and traceability requirements
Dietary supplement labels must include a domestic adverse-event contact to comply with the Dietary Supplement and Nonprescription Drug Consumer Protection Act. This means a U.S. address or a U.S. phone number must appear on the label. A foreign address alone does not satisfy this requirement, even if the product is manufactured abroad and distributed by a U.S. entity.
Lot or batch codes serve a different but equally critical compliance function. FDA does not prescribe a specific format for lot codes, but the code must be present and must allow the manufacturer to trace the product back to a specific production run. In a recall scenario, a missing or illegible lot code can force a manufacturer to pull an entire product line rather than a targeted batch. Printing lot codes on the label itself (rather than only on outer cartons) is the safest practice.
Label and formula consistency is the third element in this category that generates FDA citations. Version drift between formula master records and label artwork is a leading cause of noncompliance. A formula update that adds a new excipient, changes a supplier, or adjusts a serving size must trigger a formal label revision before the updated product ships. Many manufacturers maintain the formula in one system and the label artwork in another, with no automated link between them. That gap is where version drift happens.
Pre-print compliance checklist:
- Confirm label artwork matches the current formula master record version number
- Verify all font sizes meet FDA minimums (6-point minimum; 8-point for legibility)
- Check that the principal display panel carries the statement of identity and net quantity
- Confirm the "Other Ingredients" list reflects the current formula, including capsule shell
- Validate that every structure/function claim has an adjacent, exact DSHEA disclaimer
- Cross-reference allergen declarations against current supplier COAs
- Confirm domestic adverse-event contact information is current and U.S.-based
- Verify lot code placement and legibility on the physical label proof
Key takeaways
A fully compliant dietary supplement label requires nine mandatory elements, a precisely formatted Supplement Facts panel, exact DSHEA disclaimer wording, complete allergen declarations including sesame, and a domestic adverse-event contact, all synchronized with the current formula master record.
| Point | Details |
|---|---|
| Nine mandatory elements | Every label must carry identity, net quantity, Supplement Facts, ingredient list, manufacturer info, adverse-event contact, allergens, country of origin, and lot code. |
| Supplement Facts panel precision | Treat the panel as a controlled document; math errors, missing %DV, and improper proprietary blend disclosures are top FDA citation triggers. |
| Exact DSHEA disclaimer | The disclaimer wording is fixed by 21 CFR 101.93 and cannot be paraphrased; it must appear adjacent to every structure/function claim. |
| Allergen depth | Allergen checks must extend to capsule shells and processing aids, verified against supplier COAs, not just the active ingredient blend. |
| Version control | Formula and label artwork must be linked through a controlled document system to prevent version drift and FDA citations. |
Why label compliance is harder than it looks
From our work reviewing supplement labels at Nutrasmarts, the most consistent pattern we see is not ignorance of the rules. Most formulators know the nine required elements. The failures happen in execution, specifically in the gap between knowing a rule and operationalizing it across a product line with multiple SKUs, contract manufacturers, and marketing teams.
The Supplement Facts panel is where we see the most damage. Teams treat it as a design element rather than a regulated table. A graphic designer adjusts font sizing for aesthetics and drops below the 6-point minimum. A marketing copywriter rewrites the DSHEA disclaimer to sound "cleaner" and inadvertently creates a compliance violation. These are not malicious errors. They are process failures.
Our honest observation is that the supplement label audit process should be a formal, documented step in every product launch workflow, not a final check done informally before printing. Engaging a food-and-drug attorney or regulatory consultant for at least one full label review per product line pays for itself the first time it catches a warning-letter-level error. FDA enforcement patterns in 2025 and 2026 show continued focus on structure/function claim disclaimers and allergen declarations. Those are the two areas where we recommend spending the most review time.

FAQ
What are the nine required elements on a supplement label?
Every dietary supplement label must include a statement of identity, net quantity of contents, Supplement Facts panel, complete ingredient list, manufacturer or distributor name and address, domestic adverse-event contact, allergen declarations, country of origin, and a lot or batch code.
What is the exact DSHEA disclaimer wording?
The required text is: "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." No paraphrasing is permitted under 21 CFR 101.93.
Does sesame need to be declared as an allergen on supplement labels?
Yes. The FASTER Act added sesame as the ninth major allergen, and FALCPA allergen rules apply to dietary supplements. Sesame must be declared via a "Contains" statement or parenthetical in the ingredient list.
When must manufacturers notify FDA about a structure/function claim?
FDA notification is required within 30 days of first marketing a product with a new structure/function claim. The filing includes the claim text, ingredient name, and brand name. FDA receives but does not approve the notification.
What causes version drift on supplement labels?
Version drift occurs when formula master records and label artwork are updated independently without a formal synchronization step. Controlled document management that links formula versions to label artwork versions is the standard practice to prevent this compliance risk.
