Third-Party Testing & Certificates of Analysis

Every NutriCollect lot is tested by an independent ISO-accredited laboratory before release. Enter the lot number printed on the bottom of your bottle to retrieve that lot's Certificate of Analysis (COA). No account, no email required.

What each lot is tested for

Potency — confirms the active amount meets label claim.
Heavy metals — lead, arsenic, cadmium, mercury, against California Prop 65 thresholds.
Microbials — total plate count, yeast, mold, E. coli, Salmonella.

Lot number format

The lot number is on the bottle base: LOT-YYYY-NNNN. The four-digit year identifies the production year.

What if my lot isn't listed?

COAs are published within five business days of release. If your lot is missing, contact us and we'll send it directly — older lots are archived rather than deleted.
