VERIFICATION
Every batch independently tested — and the COA is on file.
Verification is where methodology becomes verifiable. Every Stellar production lot is analyzed at an ISO/IEC 17025 accredited laboratory before release. The certificates of analysis are documented and accessible by lot number.
THE PRINCIPLE
WHY INDEPENDENT TESTING
Verification only counts when nobody at the brand can influence the result.
Every supplement company says "third-party tested." Few of them publish the lab, the batch, the assay set, or the certificate.
Stellar's verification chain is built around a single principle: the testing layer must be operationally outside both Stellar Health Labs and Clinical Index. That's why every Stellar product is tested at an independent, ISO/IEC 17025 accredited laboratory — the certificate of analysis is issued by the lab, not by either entity.
The customer can request or verify the COA for any production lot they purchase.
WHAT EACH BATCH IS TESTED FOR
Four assay categories on every lot.
The minimum verification set for any Stellar production run. Additional assays are added per ingredient where the literature supports it.
01 · HEAVY METALS
Heavy metal panel.
Arsenic, lead, mercury, cadmium — analyzed against published safety thresholds. Out-of-spec lots are held.
02 · MICROBIAL
Microbial screen.
Total aerobic count, yeast/mold, coliforms, E. coli, salmonella. Each lot is screened before release.
03 · IDENTITY
Ingredient identity.
Each declared active is identity-tested — confirming the ingredient on the panel is the ingredient in the bottle.
04 · POTENCY
Active standardization.
Standardized actives (e.g. fulvic content, NAD+ precursor purity) are quantified against the dose on the panel.
THE COA REVIEW PROCESS
HOW BATCHES MOVE FROM LAB TO RELEASE
Three checkpoints between manufacturing and the customer.
01 · Lab receives the batch sample. The ISO/IEC 17025 accredited lab runs the assay set. The certificate of analysis is generated by the lab, signed, and dated.
02 · Clinical Index audits the COA. Each batch's COA is reviewed against the formula's declared dose and the methodology rubric. Discrepancies trigger a hold.
03 · Release is authorized only on a clean COA. Lots that fail any assay are held. Customers can verify the certificate for any unit they receive by lot number.
The chain is intentionally narrow — the lab issues, Clinical Index audits, Stellar releases. No single entity can short-circuit it.
CERTIFICATION STATUS
Two third-party marks — both used only with active authorization.
Certifications carry weight when they're real. Marketing-only certification language is not used.
01 · CONTENTS CERTIFIED
NSF Contents Certified.
NSF International verifies the contents of the product match the label. Used on Stellar products when an active authorization is on file. The mark is removed if authorization is not active.
02 · USP VERIFIED
USP Verified.
The United States Pharmacopeia verification program. Used selectively where the ingredient profile supports it and authorization is active.
