Why Supplement Quality Control Testing Matters for Brand Owners
At SREKE, we understand that rigorous quality control testing is the foundation of every successful supplement brand. Our GMP-certified facility in Guangzhou implements comprehensive testing protocols that align with FDA 21 CFR Part 111, EFSA regulations, and USP standards. Proper quality control testing protects your brand from costly recalls, ensures label accuracy, and builds consumer trust through verified product safety and potency.
Our testing programs cover incoming raw materials, in-process verification, and finished product analysis. We utilize advanced methods including HPLC for potency verification, ICP-MS for heavy metal screening, and microbiological testing to ensure every batch meets specification. This systematic approach helps brand owners navigate complex regulatory requirements while maintaining product consistency.
Key Manufacturing Considerations at SREKE
Our manufacturing facility integrates quality control testing throughout every production stage. We conduct identity testing on all incoming ingredients using FTIR spectroscopy and microscopic analysis to verify botanical sources and mineral compounds. Our potency testing ensures active ingredients meet labeled specifications within acceptable tolerance ranges.
Contaminant screening is essential for market compliance. We test for heavy metals (lead, arsenic, cadmium, mercury), pesticides, residual solvents, and microbial contaminants including E. coli, Salmonella, and total aerobic count. Our dissolution testing protocols verify tablet and capsule performance according to USP general chapters.
Documentation and traceability form our quality management system. Each batch receives a unique identifier linking raw materials to finished products. Our ISO 22000 and HACCP-certified processes ensure complete audit readiness for FDA inspections and third-party audits.
