Supplement label requirements: FDA & DSHEA basics

This is not legal or regulatory advice. Supplement labeling rules are set by the FDA, they are detailed, and they change. Nothing here states a definitive requirement for your product or market. Before you print, confirm every element against current FDA guidance and have your label reviewed by qualified regulatory or legal counsel. Treat everything below as a general orientation, not a checklist you can rely on.

How US dietary supplements are regulated

The foundational fact to understand is this: in the United States, a dietary supplement is legally a food, not a drug. The Dietary Supplement Health and Education Act — universally shortened to DSHEA — created a distinct category under the Federal Food, Drug, and Cosmetic Act and set the framework the FDA uses to oversee supplements today. That single decision cascades into almost everything about the label.

Because supplements sit inside the food framework, they inherit food-labeling conventions — a statement of identity, a net-quantity declaration, an ingredient list, and responsible-party information — and then add supplement-specific rules on top, most visibly the Supplement Facts panel that replaces the Nutrition Facts box you'd see on a conventional food. It also means the categories overlap: many of the allergen and food-contact considerations we cover in our guide to food packaging regulations apply to supplements too.

Two agencies matter here, and it's worth keeping them straight. The FDA governs the label itself — what must appear on the package and how claims are framed. The FTC polices advertising and marketing claims wherever they appear, including the label. A claim that's a problem for one is usually a problem for the other, so the safe mental model is: if you can't substantiate it, don't say it — on the label or anywhere else. This article is one piece of the complete guide to supplement packaging, which covers the formats and physical requirements the label lives on.

The label elements every supplement needs

A supplement label is built from a handful of mandatory components. The exact placement, type sizes, and panel definitions are specified by the FDA and are more nuanced than any summary can capture, so the table below describes what each element is for rather than how to format it. Use it to make sure nothing is missing, then verify the specifics.

Element	What it covers	Generally required by
Statement of identity	The name of the product and the words that identify it as a dietary supplement.	FDA (food labeling under the FD&C Act)
Net quantity of contents	How much is in the package — count, net weight, or volume — on the front panel.	FDA / FPLA
Supplement Facts panel	Serving size, servings per container, dietary ingredients, and amounts per serving.	FDA (supplement-specific)
Ingredient list	All ingredients, including non-dietary ("other") ingredients, in the required order.	FDA
Allergen information	Declaration of major food allergens present in the product.	FDA / FALCPA
Responsible party	Name and place of business of the manufacturer, packer, or distributor.	FDA
Claim disclaimer	The required statement when a structure/function claim is made.	FDA / DSHEA

The label is conventionally organized across a principal display panel (the front — what the shopper sees on shelf) and an information panel (usually the right of the front, carrying the Supplement Facts, ingredients, and responsible-party details). Which element goes where is itself governed, so don't treat the split as a design free-for-all. On very small packages the FDA provides alternatives for how information can be arranged — another reason to verify against current guidance rather than assume.

Inside the Supplement Facts panel

The Supplement Facts panel is the heart of the label and the part most specific to this category. It is the supplement equivalent of the Nutrition Facts box, standardized so a shopper can compare products at a glance. Conceptually it declares:

1. Serving size — the amount the manufacturer suggests as a serving (e.g. two capsules).
2. Servings per container — how many of those servings the package holds.
3. Each dietary ingredient — listed with the quantitative amount per serving.
4. Percent Daily Value — shown for ingredients that have an established Daily Value; ingredients without one are marked accordingly.

Two ideas trip up new brands. First, ingredients that have a Daily Value and those that don't are handled differently within the panel, and proprietary blends have their own presentation conventions — get a regulatory review of how yours is laid out. Second, the numbers on the panel are a commitment: what you declare has to match what's actually in the product within the tolerances the FDA expects, which is where good manufacturing practice and testing come in. The panel is not a place to round optimistically.

Everything in the panel also has to be legible on the finished, physical label — which sounds obvious until you're fitting a full Supplement Facts box onto the curved wall of a small packer bottle. Legibility is a compliance question, not just a design one.

Claims: structure/function versus disease

This is where supplement brands most often cross a line without realizing it. DSHEA draws a bright line between two kinds of claims, and the difference is the difference between a legal supplement and an unapproved drug.

A structure/function claim describes how an ingredient affects the normal structure or function of the body — for example, that calcium "supports strong bones" or that a botanical "helps maintain a healthy immune system." These are generally permitted for supplements. A disease claim, by contrast, states or implies that the product diagnoses, treats, cures, mitigates, or prevents a disease — "cures arthritis," "prevents the flu." Disease claims turn your product, in the eyes of the FDA, into a drug, and drugs require approval that supplements do not have.

The catch is that the line is drawn on meaning, not on magic words. Imagery, product names, and even the diseases your target audience is known to have can push an otherwise innocent phrase across into disease-claim territory. When in doubt, describe what the ingredient does for a normal, healthy body, and stop there.

Crucially, whenever you make a structure/function claim, DSHEA requires an accompanying disclaimer — the familiar language noting 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 exact wording, the placement, and how it must relate to the claim are all specified, so use the current FDA text verbatim rather than paraphrasing it. Missing or malformed disclaimers are a common and avoidable compliance gap.

Allergens, warnings, and tamper-evidence

Because supplements live inside the food framework, major food allergens present in the product generally have to be declared, following the same allergen-labeling expectations that apply to conventional foods — the ground our food packaging regulations guide covers in more depth. Beyond allergens, some ingredients carry their own warning-statement expectations, and certain populations (such as pregnant or nursing consumers) may need to be addressed depending on the formula. None of this is one-size-fits-all; it is ingredient-driven and jurisdiction-sensitive.

There is also a physical dimension to compliance that isn't printed copy at all. Many supplement products are expected to ship with tamper-evident features so a consumer can see whether the package has been opened — typically an induction seal under the cap, a shrink band, or a blister that can't be re-closed invisibly. This is closely related to, but distinct from, child-resistance.

Tamper-evident — a packaging feature that gives visible, hard-to-reverse proof that a package has been opened, such as an induction seal, shrink band, or breakaway cap ring. See more terms in the packaging glossary.

The takeaway: your labeling obligations and your packaging structure are two halves of one compliance picture. A perfect Supplement Facts panel on a package with no tamper-evidence, or an allergen declaration that omits an ingredient hiding in your capsule shell, is still a problem. Supplement brands in the nutraceuticals space generally solve the label and the package together rather than as separate projects.

Getting the artwork right on a small label

Once you know what has to appear, the practical problem is fitting it onto a small, often curved surface without any of it being trimmed, distorted, or rendered illegible on press. This is where regulatory content meets production reality, and it's where a lot of otherwise-compliant labels fail at the last step.

• Legibility survives production. Type that looks fine in the design file can close up or fill in when it's actually printed at scale. Mandatory copy — the Supplement Facts panel, the disclaimer, the ingredient list — has to stay readable on the finished label, not just on screen.
• Nothing critical lands in the trim. Required elements need to sit inside the safety margin so normal cutting and application tolerance never clips them. Our guide to label dieline and bleed specs walks through the cut, bleed, and safety margins that keep that from happening.
• Color and contrast hold up. Small warning and disclaimer text has to stay high-contrast against its background across the full print run, not just on the first sheet.
• The panel is locked, the marketing is flexible. Treat the regulated content as fixed geometry the design has to accommodate, rather than something you compress to make room for a logo.

A good rule of thumb: build the regulated content first, at a size you've confirmed is legible in production, and design the brand around it. Reversing that order is how the Supplement Facts panel ends up shrunk to illegibility to fit an oversized hero graphic.

How PackOS helps supplement brands

PackOS won't tell you whether your claims are compliant — that's a job for your regulatory team and counsel. What it does is make the production side of a compliant label reliable and fast. When you upload label artwork or a die file, PackOS detects the structure, rebuilds an editable, parametric dieline, and checks that your content respects the cut, bleed, and safety margins that keep required copy from being trimmed — the same quality checks described on the technology page. From there it produces a photoreal proof so you can see the finished label before committing, and an instant quote. In short: you and your regulatory advisors decide what the label must say; PackOS helps make sure it prints correctly, legibly, and on spec. Try it on a real file with Quick Quote.
