Quality & Safety Testing
NanoCur undergoes comprehensive independent testing by Eurofins — the world's largest testing network and one of only three labs approved by Amazon. Passed all safety and purity categories required by Amazon's third-party verification program.
The Higher Standard in Supplement Testing
Amazon requires joint health supplements to pass rigorous third-party verification through one of only three approved laboratories — Eurofins, NSF International, or UL Solutions. Eurofins sends results directly to Amazon; the brand cannot alter the data. NanoCur passed all eight certification categories.
Eurofins Report #5102972-0 Tested at Eurofins Food Integrity Innovation — Madison, WI & Brea, CA — ILAC-MRA Accredited
Zero Hidden Drugs — 12 Screened, None Detected
Some joint supplements have been found to contain undeclared pharmaceuticals including NSAIDs and steroids. NanoCur was screened using LC-MS/MS — the same forensic technology used in anti-doping laboratories — and every compound came back clean.

All Metals Below Limits of Quantification
NanoCur's finished product was analyzed for heavy metals by Eurofins labs in both India and the USA. Every result came in below the limit of detection.

| Metal | Result | LOQ | Unit |
|---|---|---|---|
| Arsenic (As) | < 0.05 | 0.05 | mg/kg |
| Cadmium (Cd) | < 0.02 | 0.02 | mg/kg |
| Lead (Pb) | < 0.05 | 0.05 | mg/kg |

Finished Product — Eurofins USA
| Metal | Result | Specification | Status |
|---|---|---|---|
| Chromium (Cr) | 0.000849 mg/serving | ≤ 0.02 mg/serving | Pass |
The chromium result is 42 times below the safety limit. Method: ICP-MS per AOAC 2011.19, 993.14, and 2015.01 (Modified).
Industry Context
A 2021 industry study by NOW Foods , verified by Eurofins Labs and the University of Georgia, found that heavy metal levels across 23 Amazon curcumin products averaged significantly higher than those in products from established quality brands. Two products exceeded California Prop 65 limits for lead. These findings illustrate why independent heavy metal testing matters when choosing a curcumin supplement.
400+ Pesticides Screened — All Below Quantification Limits
NanoCur's finished product was screened using both GC-MS/MS and LC-MS/MS methods for over 400 individual pesticide compounds. Every result was clean.
400+ compounds analyzed across two methods: GC-MS/MS (organochlorines, pyrethroids, organophosphates) and LC-MS/MS (neonicotinoids, fungicides, herbicides). All results were Below Limit of Quantification (BLQ) at an LOQ of 0.01 mg/kg.
Compliant with EU Regulation (EC) 396/2005

How to Spot a Quality Supplement
Not all supplements are created equal. Here are four things to look for before you buy — and how NanoCur meets each standard.
Look for Independent, Accredited Testing
The lab should be independent from the brand, with ISO 17025 accreditation and recognized credentials like ILAC-MRA. Self-testing or in-house results are not equivalent.
Check for Amazon TIC Verification
Products in the joint health category must pass Amazon's mandatory third-party audit through Eurofins, NSF, or UL. Results go directly to Amazon — brands cannot alter or cherry-pick data.
Demand Transparent Results
Brands should share what was tested and the actual results — not just say "third-party tested." Ask for the Certificate of Analysis with specific test methods and report numbers.
Verify Standardized Curcuminoids
Look for 95% standardized curcumin extract verified by an independent lab. Cheap turmeric root powder contains only 2–5% curcumin — far less than therapeutic levels.
Why Quality Testing Matters as Much as the Formula
Active Curcumin, No Filler
No cheap turmeric powder filler. NanoCur uses a patented cyclodextrin nanocarrier — a 3rd-generation delivery technology designed for enhanced curcumin absorption. Piperine-free, gentle on the stomach.
Comprehensive Eurofins Testing
NanoCur undergoes the full battery of tests required by Amazon's TIC program, conducted by Eurofins across specialized labs in the USA and India — covering adulterants, potency, heavy metals, pesticides, mycotoxins, and microbiology. Many brands undergo limited testing or none at all.
Unbiased, Direct-to-Amazon Reporting
Eurofins sends test results directly to Amazon. NanoCur cannot alter, edit, or selectively share the data. This chain-of-custody model represents the highest standard of supplement verification available today.
Clean Label, Verified
No GMOs, artificial ingredients, fillers, chemicals, color additives, binders, or preservatives. Vegan capsules (not gelatin). Every claim on the label has been independently substantiated by Eurofins testing.
Eurofins Testing Program — Full Scope
Eurofins conducted comprehensive testing on the same NanoCur production batch (C540425 / Lot 3501010625A) across multiple Eurofins laboratories to cover the full range of analyses required by Amazon's joint wellness supplement program.
