Why Supplement Quality Control Testing Matters for Brands

At SREKE, we understand that supplement quality control testing is the foundation of consumer trust and regulatory compliance. As a GMP-certified dietary supplement manufacturer in Guangzhou, we implement rigorous testing protocols to ensure every product meets FDA and EFSA standards without making disease treatment claims.

Key Manufacturing Considerations at SREKE

We conduct comprehensive quality control testing across five critical areas:

  • Potency Analysis: HPLC and UV-Vis spectroscopy verify active ingredient concentration matches formulation specifications
  • Microbial Testing: Total aerobic count, yeast/mold, E. coli, Salmonella, and Staphylococcus aureus testing per USP <61>
  • Heavy Metal Screening: ICP-MS analysis for lead, arsenic, mercury, and cadmium with limits below California Proposition 65 thresholds
  • Residual Solvent Testing: GC-MS verification ensuring no solvent residues exceed ICH Q3C guidelines
  • Dissolution Testing: USP apparatus methods for tablets and capsules to confirm bioavailability

How SREKE Helps You Get to Market Faster

Our integrated quality system reduces time-to-market while maintaining compliance:

  • MOQ Flexibility: Softgels (10,000 units), capsules (5,000 units), tablets (8,000 units), powders (2kg minimum)
  • Standard Lead Time: 4-6 weeks from approved formula to finished goods including QC validation
  • Formulation Support: Our R&D team adjusts formulations for stability during accelerated aging studies
  • Packaging Compliance: Child-resistant containers and tamper-evident seals meet FDA 16 CFR Part 1700 requirements
