Amazon’s New Dietary Supplements Policy: What Sellers Must Fix Before March 31 2026

TL;DR

Amazon will begin enforcing a major dietary supplements policy update from March 31 2026. All supplement listings must exactly match the product’s Supplement Facts Panel, including ingredient names, amounts, serving sizes, and any numerical or equivalency claims.


In addition, third party verification of cGMP compliance and product testing is now mandatory for all supplements.


Note: Amazon’s new food supplements compliance rules are being enforced across its global marketplaces, including the UK, EU and US. Some references, such as FDA cGMP and NSF/ANSI testing standards, relate specifically to the US marketplace. UK/EU sellers should follow equivalent local regulations in addition to Amazon’s platform requirements.

What’s Changing?


Amazon is rolling out one of its most significant food supplements enforcement updates to date, with full enforcement beginning 31 March 2026.


If you sell food supplements on Amazon, whether private label, branded, or white label, this is not a minor policy refresh. It represents a structural shift in how Amazon evaluates supplement listings, labels, and manufacturing compliance.


At the centre of the update are two requirements that now apply across the entire supplements category:


  • Exact matching between your product listing and the physical Supplement Facts Panel.


  • Mandatory third party verification of cGMP compliance and product testing.


Why Amazon Is Enforcing This Now


Amazon has faced increasing scrutiny around supplement quality, inflated ingredient claims, and inconsistent labelling, particularly where listings rely on equivalency language or implied potency that is not clearly reflected on the label itself.


Rather than addressing these issues on a case by case basis, Amazon is now tightening enforcement at scale. Automated reviews and documentation checks are being used more aggressively, and sellers are increasingly expected to meet the same evidentiary standards as larger, established brands.


Element 1: Exact Matching to the Supplement Facts Panel


Amazon now requires that every ingredient related claim in your product listing aligns exactly with what appears on the Supplement Facts Panel.


This includes:


  • Ingredient names

  • Amounts per serving

  • Serving sizes

  • Any numerical, potency, or equivalency claims


If a claim is not clearly and explicitly reflected on the label, it should not appear in your listing.


Common High-Risk Issues


Conversion and Equivalency Claims: One of the highest risk areas is the use of extract to raw material conversions.


For example:


  • A listing claims “4,000 mg raw turmeric root per serving”

  • The label states 400 mg turmeric extract (standardised to 95% curcuminoids)


Even if the maths can be explained, Amazon does not treat these as equivalent unless the equivalency is clearly stated and substantiated on the label itself.


Listings that imply higher ingredient amounts through conversion language are being flagged as misleading.


Numerical Mismatches in Active Delivery


Another frequent issue involves how much of an active compound is actually delivered.


For example:


  • A listing claims “1,500 mg EGCG per serving”

  • The label states 750 mg green tea extract standardised to 50% EGCG


This delivers approximately 375 mg EGCG, not 1,500 mg.


Amazon considers this a numerical mismatch, regardless of how the claim is framed.


Serving Size and Portion Confusion


Serving size discrepancies are also under closer scrutiny.


Split panels (for example, 1 scoop versus 2 scoops) are permitted, but listings must clearly reflect how the claimed amount is achieved.


If a product delivers 8,000 mg only when multiple servings are used, that context must be clear and consistent across both the label and the listing.


Ingredient Naming and Identity


Ingredient naming issues are generally lower risk but still enforced.


Amazon expects:


  • Common or usual ingredient names

  • Correct identification of plant parts

  • Latin binomials where required


Simplifying or renaming ingredients for marketing purposes can create avoidable compliance issues.


Element 2: Third-Party cGMP and Product Verification


In addition to listing accuracy, Amazon now requires independent third party verification that food supplements are:


  • Manufactured in cGMP compliant facilities

  • Tested for identity, potency, purity, and contaminants

  • Accurately labelled in line with the Supplement Facts Panel


Seller provided Certificates of Analysis on their own are no longer sufficient.


What Amazon Will Accept


Amazon recognises testing and certification from approved third party organisations, as well as established certification standards such as NSF/ANSI programmes.


Documentation must be:


  • Current

  • Issued by recognised third parties

  • Uploaded through Seller Central’s Manage Your Compliance dashboard


This is not a one off requirement. Certification and testing must be maintained and renewed on an ongoing basis.


What Happens If You’re Not Compliant?


Sellers who do not meet these requirements may experience:


  • Listing suppression or deactivation

  • Documentation requests with short response windows

  • Delays in reinstatement

  • Revenue disruption that is difficult to recover


Once a listing is deactivated, resolving issues retrospectively is often slower and more expensive than addressing them in advance.


What Sellers Should Review Now


If you sell food supplements on Amazon, it is worth reviewing the following as soon as possible:


  • Do all ingredient claims exactly match the Supplement Facts Panel?

  • Are any conversions or equivalency claims implied in the listing?

  • Is serving size messaging clear and consistent?

  • Are ingredient names and plant parts accurate?

  • Is your manufacturer independently cGMP certified?

  • Do you have acceptable third-party testing documentation ready if requested?
