Traceable Sources and Batch-Specific Quality Data
SNQ examines ingredient sources, Certificates of Analysis (COAs), and incoming inspection records to verify identity, specifications, and quality. The product’s three core ingredients come from established U.S. and European suppliers, with defined standards for key active compounds.
Percentages below refer to raw ingredients, not finished capsules. OptiLut® and FloraGLO® figures are reviewed-batch results; Mirtoselect® shows the minimum specification.
Supplied by U.S.-based NutriScience Innovations, each batch undergoes HPLC identification and carotenoid quantification. The reviewed batch contained 21.01% lutein and 4.28% total zeaxanthin (trans + meso), meeting supplier specifications. Heavy-metal and microbial controls provide additional safety evidence within traceable batch records.
Produced by Italy’s Indena, this extract is standardized to ≥36% total anthocyanins by HPLC. Quality checks include TLC identification, ICP-MS heavy-metal testing, and radioactivity and microbial testing.
Manufactured by DSM’s Vitatene in Spain, with batch-specific analytical records and UV/HPLC quantification. The reviewed batch contained 11.0% lutein and 0.9% zeaxanthin, exceeding specified minimums. Microbial testing follows European Pharmacopoeia methods, with release approved by the manufacturer’s quality department.
Limiting Environmental Exposure During Filling
Lutein and zeaxanthin are sensitive to air, light, temperature, and humidity.
Beyond ingredient selection, SNQ considers how manufacturing processes help protect these sensitive compounds.
Reduces powder exposure to air, light, and ambient humidity.
Automated equipment operates at more than twice the speed of semi-automatic equipment, reducing the time ingredients remain exposed during production.
The contract manufacturer follows ISO 22000- and HACCP-based procedures for filling, hygiene, and quality records, supporting consistency and traceability.
Verifying What Each Capsule Contains
SNQ reviews third-party quantitative testing to extend verification beyond raw-material specifications and formulation inputs to actual finished-product content.
These results provide documented evidence of actual content, complementing records of the amounts added during formulation.
Traceable Sources and Batch Data Make Quality Verifiable
Ingredient quality depends on traceable origins, clear specifications, and batch-specific COAs and analytical data. These records substantiate ingredient identity, active-compound content, and safety specifications.
Black Currant & Lutein extends this approach through protective filling processes and third-party finished-product testing. For SNQ, the value of ingredient selection lies not only in brand or origin, but in a documented quality system that supports ongoing traceability and verification—from raw materials to finished capsules.
