Many brand owners assume that outsourcing manufacturing also outsources the risk. It doesn’t. When a supplement label is wrong — an overstated claim, a missing disclaimer, an inaccurate Supplement Facts panel — the FDA comes for the name on the front of the bottle. That’s your brand, not the factory.
Understanding where label responsibility actually sits is one of the most important — and most misunderstood — parts of running a supplement brand. Here’s how it works and how to protect yourself.
Under the FD&C Act and DSHEA, the firm that markets a dietary supplement is responsible for ensuring the product is not adulterated or misbranded. In plain terms: the brand owner is responsible for the accuracy and compliance of the label. If the label is wrong, the FDA can issue a Form 483, a warning letter, or order a recall — directed at your company.
Contract manufacturers do carry obligations for the operations they perform, but that does not transfer label liability away from you. Outsourcing the work does not outsource the responsibility.
A compliant label under 21 CFR Part 101 includes:
Most label trouble isn’t exotic. It’s these:
| Mistake | Why It’s a Problem |
|---|---|
| Disease claims | Turns a supplement into an unapproved drug in the FDA’s eyes |
| Missing disclaimer | Required whenever you make a structure/function claim |
| Label doesn’t match the batch | What’s declared must equal what’s tested and present |
| Unsubstantiated claims | Every claim needs evidence you can produce on request |
You can’t delegate the responsibility, but you can build a system that keeps you compliant:
A strong contract manufacturer won’t take the liability off your shoulders — no one can — but they will hand you accurate batch documentation, CoAs that match the panel, and a quality agreement that defines responsibility cleanly. That’s the difference between a partner who helps you stay compliant and a vendor who leaves you exposed.
The brand owner is responsible for label accuracy and compliance. The manufacturer is responsible for the operations it performs, but FDA enforcement on a misbranded label targets the marketing firm — your brand.
The FDA can issue a Form 483, a warning letter, or require a recall. These actions name the brand and can halt sales, so prevention through review and documentation is essential.
No. Any structure/function claim requires the FDA disclaimer stating the claim hasn’t been evaluated by the FDA and the product isn’t intended to diagnose, treat, cure, or prevent disease.
