agency for supplement brands on Amazon: grow without the suppressions.

Why is selling supplements on Amazon so hard?

Supplements are one of the most regulated categories on Amazon, and the rules come from two directions at once: US law (the FDA and FTC) and Amazon's own policies, which are often stricter than the law and change without much notice. A listing that was fine last quarter can be suppressed tomorrow. Here is what makes the category different. Policy details below are summarized generally; always confirm current requirements in Seller Central.

• Category approval and gating. Dietary supplements typically require approval or category-specific verification before a listing can go live, and some sub-categories and ingredients carry extra restrictions. New sellers often discover this only after inventory is already made.
• Third-party testing and a Certificate of Analysis. Amazon's dietary supplement policy has required verification through an approved third-party testing, inspection and certification (TIC) organization. In practice, expect to show that products were tested for identity, purity and label accuracy, backed by a Certificate of Analysis (CoA), the lab document confirming what is actually in the batch.
• cGMP manufacturing. Supplements must be made under current Good Manufacturing Practice rules (FDA's 21 CFR Part 111). Amazon and testing organizations generally expect evidence that your manufacturer follows them. A cheap contract manufacturer that can't produce the paperwork becomes your problem.
• Structure/function claims vs. disease claims. Under DSHEA (the Dietary Supplement Health and Education Act of 1994), a supplement may say it supports a normal body structure or function, such as "supports healthy joints." It may not claim to diagnose, treat, cure or prevent a disease, such as "relieves arthritis." That line is where most suppressions start.
• The FDA disclaimer. Any structure/function claim must carry the standard disclaimer: "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." It belongs on the label, and Amazon generally expects label images to match the listing.
• Restricted and prohibited ingredients. Some ingredients are banned outright (ephedrine alkaloids, for example) and others, such as DMAA, are treated by the FDA as unlawful in supplements. Amazon also restricts ingredients that are legal elsewhere. Check Amazon's restricted products pages before you formulate, not after.
• Review manipulation by competitors. Supplements attract bad actors: fake negative reviews, false safety complaints filed to trigger a review of your listing, and hijackers on your detail page. Defending against this is ongoing work, not a one-time fix.
• Compliance-driven suppressions. Amazon's automated systems scan titles, bullets, images and backend keywords for risky words. One term in the wrong place can take a best-seller offline, and the notification rarely tells you exactly which word triggered it.

How do you sell supplements on Amazon? Step by step

This is the order that avoids the most expensive mistakes. Requirements shift, so treat it as a sequence to follow and verify each step against Amazon's current policy pages.

1. Check the ingredients against Amazon's restricted list first. Before you sign with a manufacturer, confirm every ingredient is allowed on Amazon and in the US. Reformulating after production is the costliest fix in the category.
2. Choose a cGMP-compliant manufacturer. Ask for their cGMP documentation and whether they have supported Amazon-selling brands through testing before.
3. Write label claims under DSHEA. Structure/function language only, the FDA disclaimer where required, and a Supplement Facts panel that matches the formula exactly.
4. Register a trademark and enroll in Brand Registry. Brand Registry protects your listings from hijackers and unlocks A+ Content and Brand Stores. Our Amazon Brand Registry guide walks through the requirements.
5. Get third-party testing and a Certificate of Analysis. Test each product through an Amazon-accepted testing organization and keep the CoA and lab reports organized by batch.
6. Apply for category approval. Submit the documents Amazon requests in Seller Central, with product and label images that match exactly what ships.
7. Build compliant, conversion-focused listings. Title, bullets, images, A+ Content and backend keywords that sell benefits without crossing into disease claims.
8. Launch with a restricted-category ad structure. Keyword targeting that avoids disease terms, tight negatives and bids tied to a margin-based target ACoS. ACoS is ad spend divided by ad revenue.
9. Enroll in Subscribe & Save and monitor account health weekly. Track suppressions, policy warnings, review patterns and inventory so problems are caught in days, not months.
