All dietary supplements sold on Amazon are subject to strict compliance requirements. You are expected to meet safety, manufacturing, and documentation standards that vary depending on the type of product you sell.
This category has become more structured in recent years. Amazon now enforces both product testing and GMP verification through approved third-party providers. While not every product requires the same level of testing, every seller must be ready to respond when a request is triggered.
At first, the process can feel confusing. That’s why we’re here. This guide covers everything you need to know about Dietary Supplements compliance on Amazon in 2026.
Third-Party Testing vs GMP Certification
Amazon separates dietary supplement compliance into two main paths:
- GMP certification or verification
- Third Party Testing
Only high-risk categories require additional product testing:
- Sexual enhancement products
- Weight management products
- Sports nutrition and bodybuilding supplements
- Joint health products
All other dietary supplements typically require GMP certification validation through approved third-party organizations.

Understanding which path applies to your product is key. Everything else in the process depends on it.
Dietary Supplements Compliance: How Does Third-Party Testing Work?
The overall compliance process on Amazon is similar across categories, generally involving a notification, an appeal, and providing third-party testing. You will see this in the Performance Notifications section inside Seller Central:
Each notification includes a detailed breakdown of your listing’s current status.
Then you will see a chart providing an overview of the issue. It’s likely you won’t get many details about the exact documents you need in this notification. But here is where you will first notice that your product requires Third-Party Testing.
You will see exactly what you need to provide in the Policy Compliance section, which you can access through Account Health:
In this very same tab, you will see your whole list of products that need compliance documents, listing tweaks, ingredient lists, etc. You submit the needed information by clicking on the right button:
In the case of Third Party Testing, you’ll have two options:
1. Ask for a compliance verification
2. Appeal the request
If you go for the compliance verification, you’ll have a complete list of Amazon-approved TIC providers that fit your specific case. Filter to your country and pick one. This is the complete list:
As you can see, you will have some options to choose from. Once you choose one, you’ll need to send them a Test Request Form to start the process. Amazon will provide all the details in the Account Health section, along with a detailed template outlining the instructions and fields you need to fill out. This is what it looks like:
Tips & Best Practices For a Successful Third-Party Testing
Here are some tips & best practices to have a successful Third-Party Testing:
1. Know Your Final Date
Amazon usually gives you a reasonable timeframe to deal with the testing. Around the 3-month mark. Annotate this on your calendar.
During this period, your listing will be “flagged,” but performance or visibility will NOT be affected.
If the due date passes and you haven’t delivered a satisfactory document, your listing will be removed.
2. Know Your Providers
You must know that not all services are the same. Each of these providers is a private company with its own approach to its clients.
If you know any other sellers you trust who have gone through this, ask them to recommend one to you.
Either way, we advise you to reach out to three or five of these providers and choose the one that best suits your needs. Look for:
- Clear communication from the first interaction
- Quick response time
- Professional guidance
Having a communicative partner is crucial because delays in receiving test results by the deadline can create significant stress. And risk listing suppression until the provider approves you.
3. Act Quickly
Even though you have three months, you have to act quickly in case something happens along the way.
Third-Party Testing is common; all sellers in the Dietary Supplements category have to face it sooner or later. But delays can happen with your testing.
Maybe it goes wrong the first time. It can happen. But if you send it early, you will have time to send another sample and have your document ready by the expected date.
4. Take Advantage of the Opportunity
Third-Party Testing isn’t asked for all the time. Amazon usually sends requests randomly… and different variations of a product have equal chances of being requested for a test, especially if your product varies by color.
If a product has multiple variations that use the same materials and production processes, testing conducted for one variation can potentially be reused to cover all others. This is the case for the same supplement, which comes in 30- or 90-capsule packs.
Many sellers assume that if you verify one variation, the others are automatically verified too since they’re the same product. But as most of this process is automated and those two variations have different ASINs, many times they’re considered to be different products from the perspective of the Amazon algorithm.
This all-in-one verification has to be arranged with your provider; let them know if that’s the case.
It is important to plan ahead to include all existing and upcoming variations in a single test to avoid the need for retesting later
And if you let the opportunity pass, and Amazon requires a verification for an identical variation, you can always appeal the request.
5. Plan Beforehand
It is advisable for sellers launching new products to research the compliance limitations for that product type beforehand.
Being aware of compliance requirements allows you to work with manufacturers to anticipate and address potential issues related to materials, size, or origin.

GMP Certification or Verification
GMP stands for Good Manufacturing Practices.
For most dietary supplements, GMP certification is the main compliance requirement. Instead of testing the product itself, Amazon requires verification that the manufacturer follows proper production standards.
GMP verification applies to all supplements that are not considered high-risk categories.
To complete this process, sellers must work with an Amazon-approved third-party organization to validate their certification. Required documentation includes a valid, unexpired GMP certificate from an accepted certification program. The process is very similar to what we covered earlier.
GMP Verification Through an Approved Provider
If your GMP certification was issued by a non-Amazon-approved provider, it is not automatically accepted.
You must contact an Amazon-approved TIC partner to verify the validity of your existing GMP certification. You will know if you have to do this because, again, Amazon will send you a notification.
The provider will review your documentation and submit the verification directly to Amazon.
Once approved, your listings will remain compliant without further action.
- The most important factor in this process is getting the TRF ID, the number that both Amazon and the third-party laboratory use to connect and synchronize their information regarding a specific compliance request.
Tip: Use GMP Across Multiple ASINs
A single GMP certification can cover multiple products produced by the same manufacturer.
If one ASIN is flagged, you can submit all related ASINs under the same GMP verification. This helps you avoid repeating the process and reduces overall costs.
Dietary Supplements Compliance Requirements
These requirements focus on making sure dietary supplements are safe, properly labeled, and consistently manufactured. Amazon uses established U.S. regulations to verify that products meet legal standards before and after they are listed. At a high level, this means sellers must prove that what they are selling is accurately presented and produced under controlled conditions.
Official sources you can reference:
- Federal Food, Drug, and Cosmetic Act (FD&C Act)
- American National Standard Institution’s NSF/ANSI 173-2024
Conclusion
Dietary supplements compliance on Amazon follows a clear structure once you understand the two main paths: Third-Party Testing and GMP verification.
The key is to act quickly when a request is triggered, choose the right provider, and use each compliance request strategically to cover as many products as possible.
With the right approach, you can reduce costs, avoid disruptions, and keep your listings active in the long term.
