Supplement Packaging and Label Compliance Checklist
Your supplement label is a regulated document. Getting it wrong leads to FDA warning letters, retail rejection, and product recalls. This guide covers what the FDA requires, what to watch for, and the most common mistakes brands make.
Dietary supplement manufacturers must comply with 21 CFR Part 111 (Current Good Manufacturing Practice for dietary supplements). This includes requirements for personnel, facilities, equipment, production, laboratory operations, and record-keeping.
Required Label Elements
Every dietary supplement sold in the United States must include these elements under 21 CFR 101.36 and the Dietary Supplement Health and Education Act (DSHEA).
Statement of identity
The term 'dietary supplement' must appear on the principal display panel along with the product name. The type of supplement should be identified (e.g., 'Vitamin D3 Dietary Supplement').
Net quantity of contents
The count of capsules, tablets, or gummies, or the net weight for powders and liquids. Must appear on the principal display panel in both metric and US customary units where applicable.
Supplement Facts panel
Lists all dietary ingredients with amounts per serving, percent daily value (%DV) where established, serving size, and servings per container. Must follow the FDA's specific formatting requirements for fonts, lines, and layout.
Other ingredients list
Non-active ingredients (fillers, binders, coatings, flavors) listed in descending order of predominance by weight. Appears below the Supplement Facts panel.
Manufacturer/distributor information
Name and place of business (city, state, ZIP) of the manufacturer, packer, or distributor. If the label names a distributor rather than the manufacturer, it must include 'manufactured for' or 'distributed by' language.
Directions for use
Suggested serving size and how to take the product. Avoid drug-like dosage language. Say 'Take one capsule daily with food' rather than 'Dosage: 1 capsule twice daily.'
Understanding Claims
What you can and cannot say on your label is one of the most common areas where brands get into trouble. There are three categories of claims, each with different rules.
| Claim Type | Example | FDA Requirement | Risk |
|---|---|---|---|
| Structure/function | "Supports bone health" | Disclaimer + 30-day FDA notification after first use | Low (if done correctly) |
| Nutrient content | "High in calcium" | Must meet FDA-defined thresholds (21 CFR 101.54) | Medium |
| Health claim | "May reduce risk of osteoporosis" | FDA pre-authorization required (limited approved claims) | High (most brands should avoid) |
| Disease claim (prohibited) | "Treats arthritis" or "Cures insomnia" | Not permitted for supplements | Warning letter or product seizure |
Required disclaimer for structure/function claims: “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.”
Common Labeling Mistakes
- Disease claims disguised as structure/function claims. Words like "treats," "cures," "prevents," or naming specific diseases turn a structure/function claim into a prohibited disease claim. "Supports joint comfort" is acceptable. "Treats arthritis pain" is not.
- Incorrect Supplement Facts formatting. The FDA specifies exact formatting: 8-point type minimum, specific line weights, hairline rules between ingredients. Many printers and designers are unfamiliar with these requirements and use standard nutrition label formatting instead.
- Missing allergen declarations. Even trace amounts from shared manufacturing equipment must be disclosed. The FASTER Act added sesame as a major allergen in January 2023. Many labels created before then need updating.
- Proprietary blend without total weight. Proprietary blends must list the total combined weight and individual ingredients in descending order of predominance. Listing ingredients without the total blend weight violates FDA requirements.
- Using %DV for ingredients without an established daily value. Ingredients like turmeric, ashwagandha, and many botanicals have no FDA-established daily value. These should show a dagger symbol with "Daily Value not established" rather than a percentage.
State-Level Requirements
Federal FDA requirements are the baseline. Several states add their own rules that apply if you sell or distribute in those states.
- California (Prop 65): Products containing ingredients on California's Proposition 65 list must carry a specific warning label. This includes some common supplement ingredients like lead (found naturally in some botanicals) and certain herbal extracts.
- New York: Requires registration of dietary supplement manufacturers and distributors selling in the state. Annual registration fees apply.
- Utah: As the largest supplement manufacturing hub in the US, Utah has additional enforcement mechanisms and works closely with the FDA on facility inspections.
- Several states: Require separate product registration for supplements sold within their borders. Check requirements for each state where you plan to sell.
Pre-Print Review Checklist
Before sending your label to print, verify each of these items. Reprinting labels after a compliance issue is expensive and delays your launch.
Frequently Asked Questions
What is required on a dietary supplement label?
The FDA requires six elements on every dietary supplement label: (1) statement of identity (what the product is), (2) net quantity of contents, (3) Supplement Facts panel listing all ingredients and amounts, (4) ingredient list for non-active ingredients, (5) name and address of the manufacturer, packer, or distributor, and (6) adequate directions for use. These requirements are defined in 21 CFR 101.36 and the Dietary Supplement Health and Education Act (DSHEA).
What is the difference between a health claim and a structure/function claim?
Health claims describe a relationship between a substance and a disease or health condition and require FDA authorization (e.g., 'calcium may reduce the risk of osteoporosis'). Structure/function claims describe how a nutrient affects the body's structure or function without referencing disease (e.g., 'supports bone health'). Structure/function claims require a disclaimer stating the claim has not been evaluated by the FDA and the product is not intended to treat disease. You must also notify the FDA within 30 days of first marketing with a structure/function claim.
Do supplement labels need to list allergens?
Yes. Under the Food Allergen Labeling and Consumer Protection Act (FALCPA) and the FASTER Act, supplements must declare the presence of major allergens: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. This applies whether the allergen is an intentional ingredient or present through cross-contact during manufacturing. Allergens must be declared in the ingredient list or in a separate 'Contains' statement.
What are common FDA warning letter triggers for supplement labels?
The most common triggers are: (1) disease claims disguised as structure/function claims (using words like 'treats,' 'cures,' 'prevents,' or naming specific diseases), (2) missing or incorrect Supplement Facts panel formatting, (3) using drug-like dosage language ('take two tablets twice daily' vs. serving size guidance), (4) failing to include the required structure/function claim disclaimer, and (5) not listing all ingredients or listing them in the wrong order. The FDA issues hundreds of warning letters annually for labeling violations.
