Saffron Testing Results
Quality Assurance & Transparency
At PrimoNourish, product quality and transparency are central to our commitment to customers.
Our Saffron Flower Extract capsules undergo quality testing by the manufacturer and independent third-party laboratory testing. These evaluations cover important quality parameters, including botanical identity, microbiological quality, and heavy metals.
The reports below document testing performed on the identified production lot.
Â
Independent Third-Party Laboratory Testing
Our saffron capsules were independently tested by Certified Laboratories (Certified Group - Tustin), an ISO/IEC 17025:2017-accredited laboratory.
Independent testing included:
-
Botanical Identity Testing (HPTLC): High-Performance Thin-Layer Chromatography testing confirmed that the sample exhibited characteristics consistent with an authenticated saffron reference standard (Crocus sativus L.). The laboratory reported "ID Confirmed."
-
Microbiological Testing: Testing for specified microorganisms, including screening for selected pathogens.
-
Heavy-Metal Screening: Analysis for arsenic, cadmium, lead, and mercury.
The reported heavy-metal results were within the specifications listed in the laboratory report.
Independent testing by an ISO/IEC 17025-accredited laboratory confirmed botanical identity using HPTLC and included microbiological analysis and heavy-metal screening. The reported heavy-metal results were within the laboratory's listed specifications.
