Supplement Labeling Requirements: What Every Brand Needs to Know Before Going to Market

Labeling is where good products often run into avoidable trouble. An inaccurate Supplement Facts panel or a claim that crosses the line can lead to FDA warning letters, retailer rejections, and in the worst cases a recall, none of which is what you want after months of work on a formula.

The good news is that supplement label requirements are clear once you understand them, and most mistakes are easy to prevent. This post walks through what the FDA requires on a dietary supplement label, the parts of the Supplement Facts panel, the rules on what you can and cannot claim, and what is changing in the regulatory picture heading through 2026.

The goal is a plain overview so you can get to market with confidence. This is not legal advice, and any specific label should be reviewed by a qualified regulatory professional before it prints.

Supplement Label Requirements: The 5 Required Elements

Every dietary supplement sold in the United States has to carry five pieces of information. These dietary supplement label requirements come from the Federal Food, Drug, and Cosmetic Act and are spelled out in FDA regulations under 21 CFR Part 101. Miss one and the product is considered misbranded, even if everything inside the bottle is perfect.

1. Statement of identity, which is the name of the product and what it is, such as Vitamin C or Magnesium Glycinate. It tells the shopper what they are holding.
2. Net quantity of contents, the amount in the package, such as 60 capsules or 8 fluid ounces. This goes on the front of the label, usually called the principal display panel.
3. Supplement Facts panel, the boxed table of nutritional information. This is the heart of the label and gets its own section below.
4. Ingredient list. Anything not already declared in the Supplement Facts panel has to be listed here, including capsule shells, fillers, flow agents, binders, and natural flavors. These are often called other ingredients and are listed in order from most to least by weight.
5. Name and place of business of the manufacturer, packer, or distributor. A shopper, or the FDA, needs to know who stands behind the product and how to reach them.

Get these five right and you have the basic structure of a compliant label. The detail that causes the most trouble lives in the panel itself.

Inside the Supplement Facts Panel

The Supplement Facts panel is the most format sensitive part of the whole label, and it is where new brands most often slip. The FDA sets specific rules for what goes in it and how it is laid out. When you create a supplement facts label, these are the details that matter most.

Start with serving size and servings per container. The serving size is the amount a person takes at one time, such as two capsules, and servings per container tells them how many of those servings the package holds. These numbers have to match the rest of the panel and your directions for use.

Next is the amount per serving for each dietary ingredient. For every active ingredient, the panel lists how much is in one serving, by weight. Where the FDA has set a Daily Value for an ingredient, the panel also shows the percent Daily Value, which tells the consumer how that amount compares to general daily intake guidance. For ingredients without an established Daily Value, that figure is left out.

Proprietary blends have their own rule that catches many brands off guard. If you group several ingredients into a blend, you can list those ingredients by name in order of weight, but you must declare the total weight of the blend. You do not have to break out the exact amount of each ingredient inside it, which is why blends are popular, but the total has to be honest and accurate.

Formatting and ordering matter more than people expect. The FDA prescribes minimum type sizes, specific bar thicknesses around the panel, the order ingredients appear in, and where the panel sits relative to the ingredient list and the company information.

A panel that is technically accurate can still be noncompliant if the layout is wrong, which is exactly the kind of thing that benefits from a careful review before printing.

Claims: What You Can and Cannot Say

Claims are where good intentions get brands into the most serious trouble. What you say about a supplement is regulated just as tightly as the panel, and the line between an allowed claim and a prohibited one is not always obvious.

Supplements are allowed to make what the FDA calls structure and function claims. These describe how an ingredient supports the normal structure or function of the body. Saying that calcium supports strong bones, or that fiber supports digestive health, is allowed, as long as the claim is truthful and you can back it up.

Any product that makes one of these claims must also carry the FDA disclaimer, the familiar statement that the claims have not been evaluated by the FDA and that the product is not intended to diagnose, treat, cure, or prevent any disease.

What supplements cannot do is make disease claims. A disease claim says or implies that the product treats, prevents, or cures a specific condition. The moment a label suggests a product does the work of a drug, the FDA can treat it as an unapproved drug, which is a serious problem.

The tricky part is the gray area between the two. A few quick examples make the line clearer.

• Permitted: supports a healthy immune system.
• Not permitted: prevents colds and the flu.
• Permitted: helps maintain healthy cholesterol levels already within a normal range.
• Not permitted: lowers high cholesterol.
• Permitted: supports joint comfort and flexibility.
• Not permitted: treats arthritis.

The permitted versions describe support for normal function. The versions that are not permitted name a disease or promise to fix a medical condition. When you are unsure which side of the line a phrase falls on, treat that as a signal to get it reviewed rather than a judgment call to make on your own.

One current detail is worth knowing. The FDA has been reconsidering exactly where the required disclaimer must appear on a label, and has signaled some flexibility while it works through a possible change. The underlying rule that you need the disclaimer when you make these claims still stands, so the safe move is to keep including it as required.

Labeling Rules in 2026 and What Is Changing

Supplement labeling does not change every year, but the rules do evolve, and 2026 is a good moment to confirm your label reflects the current standard.

The foundation has not changed. Dietary supplement labeling is governed by the Federal Food, Drug, and Cosmetic Act as amended by the Dietary Supplement Health and Education Act of 1994, with the specifics in 21 CFR Part 101.

The current Supplement Facts format, including the updated Daily Values, has been required for several years. The FDA phased that update in by company size, with larger companies required to comply first and smaller companies given extra time, and those deadlines have long since passed.

In practice that means any label printed today should already be built to the current format. If you are working from an older template, that is the first thing to check.

The next compliance horizon to plan around is January 1, 2028. The FDA has set that as the uniform compliance date for new food and supplement labeling regulations published between January 1, 2025 and December 31, 2026.

In plain terms, if the FDA finalizes a new labeling rule during this window, brands will generally have until the start of 2028 to bring their labels into line. The agency sets these uniform dates so companies are not forced to redesign labels on a separate schedule for every rule.

A couple of active developments are worth watching. The FDA has been reconsidering the rule about where the structure and function disclaimer must appear, as noted above, and enforcement on claims, new ingredient notifications, and good manufacturing practices remains a clear priority. That is a useful reminder that accuracy and substantiation matter as much as format.

For an existing brand, the practical takeaway is simple. Audit your current labels against the standard in effect today, confirm your Supplement Facts panel and Daily Values are current, and keep an eye on any new rules so you can plan ahead of the 2028 date rather than scrambling later.

For a new brand, the advice is even simpler: build your label to the current standard from day one. Designing it correctly the first time is far cheaper than relabeling a product that is already on shelves, and it keeps you out of the kind of last minute compliance rush that leads to mistakes.

How a Manufacturer Helps You Get Labeling Right

Here is the part that takes real weight off a founder's shoulders. You do not have to navigate all of this alone, and you should not have to manage labeling as a separate project off to the side.

A quality manufacturer reviews label compliance as part of the manufacturing project. That means a team that handles supplement labels every day looks at your Supplement Facts panel, your ingredient list, and your claims before the product goes into production, when problems are still cheap and easy to fix.

Catching a panel math error, a missing percent Daily Value, an out of order ingredient list, or a claim that drifts toward a disease statement at this stage is far better than discovering it after thousands of bottles are printed.

This is one of the practical advantages of working with an experienced, certified partner. Rasi Labs has been a family owned and operated custom supplement manufacturer since 1984, and label compliance review is built into the project rather than treated as someone else's job. The same facility that formulates and produces your product also helps make sure the Supplement Facts panel and the claims on the outside are accurate and compliant.

That experience sits on a serious quality foundation. Rasi Labs operates a 200,000 square foot facility on 37 acres the company owns in Cranbury, New Jersey, and is triple certified, holding NSF and cGMP certification along with registration with the FDA. Identity, potency, purity, and stability testing all happen in an in-house analytical laboratory, so the numbers that end up on your panel are backed by real data from the same building that made the product.

Because Rasi Labs does not offer private label and develops every formula exclusively for the client who owns it, the label on your bottle describes a product that is truly yours.

Good supplement label design is part of this picture too. A compliant panel still has to look clean, read clearly, and fit your packaging, and getting compliance and design to work together is much easier when one experienced partner is helping with both.

Conclusion

Labeling is not the place to cut corners. A supplement can be perfectly made and still get pulled from shelves over a label problem, which is a painful and avoidable way to lose momentum. Get the five required elements right, build an accurate Supplement Facts panel, stay firmly on the correct side of the claims line, and keep your label current as the rules evolve toward the 2028 compliance date.

The reassuring part is that none of this has to fall on you alone. A supplement manufacturer that reviews label compliance as part of the project removes much of the risk before a product ever ships, and turns labeling from a source of anxiety into one more thing handled by people who do it every day.
