Supplement label design: FDA Supplement Facts requirements

A US dietary supplement label has two jobs. The front has to sell: brand, product name, the main benefit and the count. The back has to inform, in a format the FDA defines in detail. The centre of that information is the Supplement Facts panel. This guide explains what the panel contains, what else a supplement label needs, and how to design a label that is both compliant and attractive.

It is general guidance for brands and designers, not legal advice. The definitive sources are the FDA's Dietary Supplement Labeling Guide and the regulations in 21 CFR Part 101, linked below. Always have your final label reviewed by a qualified adviser.

What counts as a dietary supplement label

In the US, dietary supplements are regulated as a category of food under the Dietary Supplement Health and Education Act (DSHEA). That means they follow food labelling rules in general, with specific rules for supplements on top. The FDA describes five main label statements:

1. Statement of identity: the name of the product, including the term "dietary supplement" or a version that names the ingredient, such as "vitamin C supplement".
2. Net quantity of contents: the amount in the container, such as the number of capsules or the weight of powder.
3. Nutrition labeling: the Supplement Facts panel.
4. Ingredient list: ingredients not listed in the panel, often under "Other ingredients".
5. Name and place of business of the manufacturer, packer or distributor.

The statement of identity and net quantity go on the principal display panel, the front of the pack customers see first. The Supplement Facts panel, ingredient list and business name usually go on the information panel, which is generally the panel immediately to the right of the principal display panel.

The Supplement Facts panel

The Supplement Facts panel is defined in 21 CFR 101.36. It looks similar to the Nutrition Facts label on food, but it has its own rules. A typical panel includes:

• the heading "Supplement Facts"
• serving size, such as "2 Capsules"
• servings per container
• an "Amount Per Serving" column
• a % Daily Value column for nutrients that have a Daily Value
• dietary ingredients that have a Daily Value, such as vitamins and minerals, listed in a set order
• other dietary ingredients without a Daily Value, such as botanicals, listed below a heavy rule, with a symbol pointing to a footnote that a Daily Value has not been established
• for proprietary blends, the blend name, the total amount of the blend and the ingredients in descending order of predominance by weight

The panel uses specific type sizes, hairline and heavy rules, and alignment. The FDA allows several formats depending on the space available, including tabular and linear formats for small packages, and formats for products with several serving sizes or for different age groups.

Common Supplement Facts mistakes

• Wrong order. Nutrients with Daily Values must follow the order in the regulation, not the order in your formula.
• Mixed units. Amounts must be in the correct units for each nutrient, such as mg, mcg or mcg DFE for folate.
• Botanicals without plant part. For botanical ingredients, the part of the plant used is usually required.
• Missing source names. If a nutrient comes from a specific source, such as calcium carbonate, that source may need to be named in the panel or ingredient list.
• Squeezed panels. Reducing type size below the minimum to fit a small label. The FDA sets minimum type sizes, and readability matters to customers too.

Other ingredients

Ingredients that are not dietary ingredients in the panel, such as capsule shells, fillers, binders and flow agents, are listed below the panel, usually after the words "Other ingredients", in descending order of predominance. If a source ingredient is already named in the panel, it does not need to be repeated here.

Allergen labelling

Dietary supplements are covered by the same major food allergen rules as conventional food. If a product contains milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans or sesame, the allergen must be declared, either within the ingredient list or in a "Contains" statement. Capsule shells made from fish gelatin, or soy-based ingredients, are common sources that brands overlook.

Claims and the FDA disclaimer

Supplement labels can make certain types of claims, but each has rules:

• Structure/function claims describe how a nutrient or ingredient affects the structure or function of the body, such as "supports healthy sleep". If you make one, the label must carry the disclaimer set in 21 CFR 101.93, and the manufacturer must notify the FDA within 30 days of marketing the product with the claim.
• Health claims describe a relationship between a substance and reduced risk of a disease. These must be authorised by the FDA or based on an authoritative statement.
• Nutrient content claims such as "high in vitamin C" have defined criteria.

Disease claims, such as "treats insomnia", are not allowed on dietary supplements. The difference between a structure/function claim and a disease claim can be subtle, and this is one of the main areas where an adviser's review is essential.

The disclaimer must be linked to each claim with a symbol, such as an asterisk, and appear in a box or on the same panel. It cannot be hidden in tiny type.

Domestic address or phone number

Supplement labels must include a domestic address or phone number through which consumers can report serious adverse events. This is often combined with the name and place of business. If your company is based outside the US, plan for a US distributor or contact on the label.

Designing a supplement label that sells

Compliance is the floor, not the goal. A label that meets every requirement can still fail on shelf if it looks cluttered or untrustworthy. Some principles we use:

Separate the two jobs

Give the front panel to the brand, the product name, the main benefit and the count, and nothing else. Keep claims short and in plain language. Move detailed information to the back, where customers expect to find it.

Build a system for the range

Most supplement brands sell several products. Set fixed positions for the brand, product name, benefit, count and form (capsules, gummies, powder), then use colour or a pattern to separate products. Customers learn the system, and new products drop in easily.

Design the panel, do not just paste it

The Supplement Facts panel is often treated as an afterthought, pasted in from a spreadsheet. Setting it properly, with consistent typography, correct rules and enough space, makes the whole label look more professional. It also makes errors easier to spot.

Test at real size and on the real container

Bottles curve, pouches gusset and jars have lids. Print the label at 100% and wrap it around the actual container. Check that the panel is readable without turning the bottle too far, and that nothing important sits on the seam.

Think about Amazon and online images

Many supplements are bought online. The front of the label needs to read clearly in a small thumbnail, and the Supplement Facts panel is often shown as its own listing image. Clean typography helps in both cases.

A practical checklist

Before you send a supplement label to print, check that you have:

• a statement of identity with "dietary supplement" or an accepted variation
• net quantity on the front panel
• a Supplement Facts panel in an allowed format, from verified data
• other ingredients listed in descending order
• allergens declared
• the disclaimer for any structure/function claims
• name and place of business, plus a domestic address or phone number
• a barcode at a scannable size, if you sell in retail
• a final review by your regulatory adviser

How we help

We design supplement labels and boxes and make printed and rigid boxes in our own factory. We typeset the Supplement Facts panel from the data you supply, keep the format consistent across your range, and make the front of the pack look like a brand people trust. We do not calculate nutrient values, decide claims or check compliance. That review stays with you and your adviser.

Questions

What is a Supplement Facts panel?

The FDA-required box on a US dietary supplement label that lists serving size, servings per container and the amount of each dietary ingredient per serving, in a defined format.

Do supplements need a Nutrition Facts label instead?

No. Products marketed as dietary supplements use a Supplement Facts panel. Conventional foods use Nutrition Facts.

When do I need the FDA disclaimer?

When the label makes a structure/function claim, such as supporting healthy sleep. The disclaimer wording is set in 21 CFR 101.93.

Can my designer check that the label is compliant?

A designer can set the panel in the right format from your data. Compliance review should be done by you and a qualified adviser.
