Updated September 22, 2025: Amazon has added Joint Health Supplements to its category of higher-risk products that require additional testing through recognized third-party labs.
Key takeaway: Amazon's Dietary Supplements policy requires third-party testing verification through a Testing, Inspection, and Certification (TIC) organization, prioritizing high-risk categories (weight loss, sexual health, bodybuilding/sports nutrition, and joint health). Sellers are prompted to submit product information and lab results through an Amazon portal coordinated with one of Amazon's recognized labs (such as Eurofins, UL, or NSF), though prior results from reputable ISO/IEC 17025–accredited labs may be evaluated. Brands should review finished-product specifications under 21 CFR § 111.70 with their manufacturers now to avoid listing suppression.
Introduction
Amazon has tightened listing requirements for dietary supplements. Historically, most sellers uploaded a manufacturer's GMP certificate and a certificate of analysis (COA) directly. Under the current verification model, Amazon requires test results verified through a limited set of recognized labs via an Amazon Seller Central workflow once a seller receives a notice. Because category scope and timelines continue to expand, brands should treat this as a priority readiness project—especially those in higher-scrutiny categories.
Who Is Affected First
Amazon is prioritizing products in:
- Weight loss
- Sexual health
- Bodybuilding / sports nutrition
Products such as multivitamins or fish oils may not be immediately affected, but expansion to additional categories is possible. Sellers will be notified by Amazon if/when their products are pulled into scope.
How the New Testing Flow Works (High Level)
-
Amazon notification: Sellers receive an email notice that testing is required for specific ASINs.
-
Portal intake: Within Amazon's portal, the seller selects a recognized lab, identifies the product, uploads the label, and provides ingredient/spec info.
-
Lab engagement & quotes: The chosen lab acts as the coordinator—confirming what needs to be tested, establishing methods, quotes, timelines, and any needed clarifications. Sellers are responsible for costs.
-
Prior data review (possible): If a brand has recent test results from a reputable ISO/IEC 17025–accredited lab or robust in-house/manufacturer COAs, the recognized lab can review those and decide whether additional testing is still required.
-
Final determination: The recognized lab reports results back to Amazon via the portal. Outcomes may include continued listing or suppression if requirements are not met.
Currently recognized labs (per Amazon communications): Eurofins, UL (Underwriters Laboratories), and NSF.
Immediate Actions for Brands (Do These Now)
1) Pull and review product specifications
- Confirm that finished product specifications are complete and defensible, not just raw material specs.
- Ensure method suitability and acceptance criteria are defined (identity, potency, microbes, heavy metals, relevant adulterants).
- Verify you can produce recent manufacturer COAs aligned to those specs.
2) Talk to your manufacturer
- Confirm they understand Amazon's direction and whether they can support with timely data and retained samples.
- Ask whether their internal lab is ISO/IEC 17025–accredited; if not, confirm which third-party lab(s) they use and the accreditation status.
- Align on turnaround times, sample pulls, and retest policies.
3) Map your lab strategy
- Identify a primary recognized lab (Eurofins, UL, NSF) for each affected product.
- If you already use a strong ISO 17025–accredited lab (not on the recognized list), package previous results for review and gap-analysis (what remains to be tested, if anything).
4) Prepare for backlog
- Expect high volumes at recognized labs during rollout.
- Assign an internal point person to monitor timelines, escalate delays, and keep Amazon deadlines visible.
- Build a calendar buffer; even perfect submissions can slip due to lab queue times.
5) Update internal SOPs
- Add an "Amazon testing" decision node to your quality/compliance workflow (when notified → portal intake → lab selection → sample logistics → review → submission).
- Clarify owner roles (Regulatory, QA, Ops) and handoffs.
What If Your Prior COAs Are From a Non-Recognized Lab?
Recognized labs may review credible data from other ISO 17025–accredited labs and determine whether additional testing is required. Brands relying on non-accredited in-house results should anticipate extra testing. Regardless, gather the best available records now (methods, results, lab accreditation certificates) to streamline review.
Risk Areas to Watch
- Lab capacity & communication: Expect slower response times. Keep escalation contacts handy.
- Method suitability & matrix effects: Some ingredients or delivery systems (e.g., certain botanicals or complex blends) need specialized methods. Be prepared to justify methods or perform method verification.
- Spec gaps: "Meets GMP" is not enough. Amazon's recognized labs will look for clear pass/fail criteria.
- Deadlines & suppression risk: Even compliant products can be late if labs are backlogged. Track due dates and document delays.
Readiness Checklist (Grab-and-Go)
- Finished product specifications (potency, identity, micro, contaminants)
- Current COAs (finished product + critical raw materials)
- Lab accreditation letters (ISO/IEC 17025)
- Method write-ups / validation summaries (as applicable)
- Internal SOP addendum for Amazon testing workflow
- Escalation contacts at chosen lab(s)
- Calendar with Amazon due dates and lab ETA buffers
Key Takeaways
- Amazon is moving supplement listings toward recognized-lab testing, starting with high-risk categories.
- Sellers will be notified and must submit through an Amazon portal, coordinating directly with a recognized lab.
- Prior ISO 17025 results may help, but additional testing can still be required.
- Get ahead by tightening specs, aligning with your manufacturer, and planning for lab backlogs.
- Update SOPs so the process is repeatable as Amazon expands categories.
FAQ
Do all supplements on Amazon need new third-party testing right now? Not immediately. Rollout is prioritized for weight loss, sexual health, and bodybuilding/sports nutrition. Additional categories may follow; Amazon will notify sellers.
Which labs are recognized by Amazon? Eurofins, UL (Underwriters Laboratories), and NSF are currently recognized. Amazon may expand the list over time.
Will Amazon accept my existing COAs? Recognized labs can review existing results—especially from ISO/IEC 17025–accredited labs—and decide whether more testing is needed.
Who pays for testing? Sellers are responsible for costs arranged with the recognized lab.
Can delays at the lab cause suppression? If results are not submitted by Amazon's due date, suppression is possible—even if the delay was outside your control. Build buffers and escalate early.
