FDA Supplement Label Design Requirements (2026 Guide)
Summary: A supplement label in the US needs five things to be legal. A statement of identity, the net quantity, a Supplement Facts panel, an Other Ingredients list, and the name and address of whoever makes, packs, or distributes it. These sit across the front of the bottle, which the FDA calls the Principal Display Panel, and the information panel next to it. Two areas cause most of the trouble. Allergens, because the FDA changed the rules in January 2025, so coconut is no longer a tree nut and goat or sheep milk now has to be named. And claims, because one disease claim can get your product treated as an unapproved drug. This guide goes panel by panel, and at every step it gives you the rule and the exact mistake that gets founders in trouble.
A supplement label has to keep two very different readers happy at the same time. A shopper looks at the front for about three seconds and decides if the product is worth picking up. The FDA reads the whole thing, every panel and every line, and decides if it is legal. The problem is that the things which make a bottle look good on a shelf are usually not the same things that keep it compliant, and the rules get very specific about sizes, percentages, and exact wording. So a label can look beautiful and still be wrong.
Most guides on this topic just list the five required elements and stop there. This one goes panel by panel, and for every element it gives you the rule, the way brands usually get it wrong, and what that means for your layout. Where the rules changed recently, and a fair amount changed in 2025, it is mentioned, because a lot of what you will read online is now out of date.
Where does each required element go?
Every required element lives in one of two places, the front of the package or the information panel to its right. Here is the full map before we go into each one.
Required element | Where it goes | What trips brands up |
|---|---|---|
Statement of identity | Front panel (PDP) | Forgetting the word "supplement" |
Net quantity | Front panel, bottom 30% | Type size scales with panel area |
Supplement Facts panel | Information panel | Using "Nutrition Facts" by mistake |
Other Ingredients | Below the Supplement Facts box | Wrong order, or too small |
Name and address | Information panel | No "Distributed by" qualifier |
Allergen statement | In or after the ingredient list | Rules changed in 2025 |
What has to go on the front of the bottle?
The front, what the FDA calls the Principal Display Panel or PDP, has to carry only two things. The statement of identity and the net quantity. Everything else can move to the side panel. For a round bottle, the area of the PDP is counted as 40% of the height times the circumference.
The statement of identity is basically the product name, written so it is clear the product is a supplement. You can put the ingredient next to the words dietary supplement, like "Vitamin C Dietary Supplement," or use a descriptive term like "Herbal Supplement." It should be bold, sit parallel to the base of the bottle, and be reasonably close in size to the largest print on the front, which in practice works out to about half the size of the biggest text. The common mistake here is a nice looking front that never actually says the word supplement anywhere. When that happens the product is not properly identified, and that alone counts as misbranding.
The net quantity is how much is inside the bottle, like "60 Capsules" or "Net Wt. 2 oz (57 g)." It has to sit in the bottom 30% of the front panel and run parallel to the base, and the smallest type size you are allowed to use depends on how big the panel is.
PDP area | Minimum type height |
|---|---|
5 sq in or less | 1/16 inch |
More than 5 to 25 sq in | 1/8 inch (about 9 pt) |
More than 25 to 100 sq in | 3/16 inch |
More than 100 to 400 sq in | 1/4 inch |
Over 400 sq in | 1/2 inch |
One practical thing. Decide the space for the net quantity in the bottom third before you start the main artwork. When founders leave it for the end, they usually have to shrink the logo to make it fit.
What goes on the information panel?
The information panel is the surface right next to the front, the one a shopper sees when they turn the bottle slightly to the right. This is where most of the legal information lives. The name and address of the manufacturer, packer, or distributor, the Supplement Facts panel, the Other Ingredients line, and the allergen statement.
The address has to be complete, with the street, city, state, and zip. And if your company did not actually make the product, you have to add a line like "Manufactured for" or "Distributed by." This matters more than it looks. Most supplement founders use a contract manufacturer, so if you print only your brand name with nothing else, you are claiming you made the product yourself, and that is misbranding again. The fix is one line, something like "Distributed by [Brand Name], [full address]."
How do you build a Supplement Facts panel that passes?
It has to say Supplement Facts, not Nutrition Facts, because Nutrition Facts is only for normal food. The whole thing sits inside a box, uses one simple typeface, and follows a fixed order from top to bottom. Get the title wrong and the product is already misbranded before you have listed a single ingredient.
Formatting:
The words Supplement Facts are bold, the biggest text in the box, and run across the full width when there is room.
Everything sits inside a border, with thin lines separating the ingredients.
One typeface only, black or a single color, on a white or plain background. The main text has to be at least 8 point, and column headings like % Daily Value and the footnotes can go down to 6 point.
Order of content:
Serving Size. The largest amount you are telling people to take at once, for example "Serving Size: 2 Capsules."
Servings Per Container. Listed right under the serving size.
Above the line ingredients. The essential nutrients the FDA calls (b)(2) ingredients, like vitamin C, calcium, vitamin D, iron, sodium, and fat, the ones that have a set Daily Value. These go in the order the FDA fixes, each with its % Daily Value.
Below the line ingredients. Botanicals, herbs, and blends that do not have a set Daily Value. Each one gets a small dagger (†) that points to a footnote saying "Daily Value not established."
Can you keep your formula secret with a proprietary blend?
You can, but there are conditions. The FDA lets you group ingredients under one named blend, like "Immunity Matrix," and you do not have to show the weight of each single ingredient inside it. But you do have to show the total weight of the blend, and you have to list every ingredient in it in order, heaviest first, indented under the blend name.
There is one hard limit. You are not allowed to hide essential vitamins or minerals, the (b)(2) ingredients, inside a blend just to avoid showing their amounts. Those always have to be listed above the line with their quantity and % Daily Value. One more thing worth knowing, even though it is not a rule. Proprietary blends are legal, but a lot of buyers do not trust them anymore, because they cannot see how much of each ingredient they are getting. The format got a bad name for what people call fairy dusting, where there is a tiny bit of the main ingredient and the rest is cheap filler. Pre workout and energy products are the usual offenders, and a few of them have been taken to court over underdosed blends. So compliant and trustworthy are not always the same thing.
How do you handle allergens in 2026?
This is the part that changed most recently, and it is also the part where a lot of the popular articles online are now wrong. The nine major allergens are milk, eggs, fish, crustacean shellfish, tree nuts, wheat, peanuts, soybeans, and sesame. Sesame became the ninth one on January 1, 2023. After that the FDA put out guidance in January 2025 that cleaned up a few definitions worth getting right.
Milk means cow milk. If you use goat or sheep milk, you have to name it as goat milk or sheep milk, because a plain milk declaration does not cover it.
Egg means chicken egg. Duck or quail eggs have to be named on their own.
Tree nuts were cut down to a list of 12, like almond, walnut, cashew, pecan, pistachio, macadamia, hazelnut, Brazil nut, and pine nut. Coconut was taken off the list, because it is actually a drupe and not a real nut, so it no longer needs a "Contains: tree nuts" line, even though it still shows up in the ingredient list.
You can declare allergens in two ways. Inline, in brackets after the ingredient, like "whey (milk)," or as a bold "Contains:" line under the ingredient list. Take this one seriously. Undeclared allergens are the most common reason supplements and foods get recalled in the US. A missing "Contains: Milk" line is the kind of mistake that pulls a whole batch off the shelves, so it is worth a lot more than a quick glance.
What can you claim before your supplement becomes a drug?
You are allowed to make structure and function claims, which describe how an ingredient supports a normal function of the body. You are not allowed to make disease claims, which is anything that says or hints the product can diagnose, treat, cure, or prevent a disease. The moment you cross that line, the FDA can treat your product as an unapproved drug.
Allowed. "Calcium supports bone health." "Supports immune function." "Helps maintain healthy energy levels."
Not allowed. "Treats anxiety." "Relieves arthritis pain." "Lowers blood pressure." The consequence here is real. It usually shows up as a warning letter from the FDA or the FTC, and it can go further, up to seizure of the product. Back in 2020 the FDA and FTC sent a wave of warning letters to supplement sellers who said their products could prevent or treat COVID-19.
If your label makes any structure and function claim, you have to add the DSHEA disclaimer, word for word:
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.
A few things people get wrong about this disclaimer. It has to be in bold, no smaller than 1/16 inch, and put inside a box when it is not sitting right next to the claim. On a single panel you can use an asterisk to connect a few claims to one disclaimer, but technically it has to appear on every panel or page that carries a claim. One thing to keep an eye on. In December 2025 the FDA told the industry in a letter that it is thinking about allowing more flexibility on where the disclaimer can go. Until the actual rule changes though, play safe and give it proper, readable space. And if you skip it completely after making a claim, you lose the protection that claim was relying on, which puts you straight back into unapproved drug territory.
The mistakes brands make most often
The front of the bottle never actually says the word supplement.
The net quantity is too small for the panel size, or it floats outside the bottom 30%.
Someone uses Nutrition Facts instead of Supplement Facts.
Only the brand name is printed, with no "Distributed by," even though a contract manufacturer made the product.
Coconut is still being declared as a tree nut, which has been out of date since 2025.
There is a structure and function claim on the label but no DSHEA disclaimer, or the disclaimer is printed so small that nobody can read it.
Essential (b)(2) vitamins are hidden inside a proprietary blend.

FAQ
Does the FDA approve supplement labels before you sell?
No. There is no approval step before you go to market. The whole responsibility sits with the brand, and the FDA steps in only after the product is already out. That is exactly why checking everything yourself before printing matters so much.
Is Supplement Facts the same as Nutrition Facts?
No. Nutrition Facts is for normal food. Supplements have to use a Supplement Facts panel, and unlike Nutrition Facts it can list ingredients that have no Daily Value, and it can also show the source of an ingredient.
Do you need the DSHEA disclaimer if you make no claims?
No. The disclaimer is only needed when you make a structure and function claim. A plain label with no such claim does not need it. But the moment you add something like "supports immunity," it becomes compulsory.
Is coconut still a tree nut allergen?
No. After the FDA guidance in January 2025, coconut is no longer treated as a major tree nut allergen, so it does not need a "Contains: tree nuts" line. It still appears in the ingredient list when you use it.
What is the smallest font size allowed on a supplement label?
The main text in the Supplement Facts panel has to be at least 8 point, and some headings and footnotes can drop to 6 point. General information like the address and the Other Ingredients line has to be at least 1/16 inch. The net quantity size depends on the size of the front panel, which is in the table above.
Can the Supplement Facts panel go on the back of the bottle?
Usually it belongs on the information panel, the one just to the right of the front. It can move only when that panel cannot be used because of the package shape. You are not allowed to hide the required information on the back just to make the design look cleaner.
What happens if a label is not compliant?
It depends on the problem. It can be anything from an FDA warning letter to a forced recall, or even seizure of the product, and for disease claims the product can be treated as an unapproved drug. Undeclared allergens are the most common reason for recalls.
The basic idea behind all of this is simple. Get the compliance right first, and then let the design sit on top of it. A label built that way looks just as good as one that ignored the rules, and it does not get you a warning letter or a recall later on.
