Why Heavy Metal Testing Matters for Supplement Brands
At SREKE, we understand that heavy metal contamination is a critical risk factor in dietary supplement compliance. Our GMP-certified manufacturing facility in Guangzhou implements rigorous testing protocols to ensure every batch meets FDA and EFSA safety standards. According to the Council for Responsible Nutrition, over 60% of consumers check supplement labels for third-party testing results before purchasing.
The Regulatory Landscape
- FDA: Requires manufacturers to ensure their products are free from harmful levels of lead, cadmium, mercury, and arsenic under the Dietary Supplement Health and Education Act (DSHEA).
- EFSA: Sets maximum allowable limits for heavy metals in food supplements across Europe.
- California Proposition 65: Mandates clear warnings if products contain known carcinogens or reproductive toxins above specified thresholds.
Key Manufacturing Considerations at SREKE
Raw Material Verification
We require all suppliers to provide Certificates of Analysis (CoA) verifying heavy metal content below established limits before materials enter our facility. Our quality control team independently tests incoming ingredients using ICP-MS (Inductively Coupled Plasma Mass Spectrometry) technology.
In-Process Controls
During production, we monitor environmental conditions and equipment integrity to prevent cross-contamination. Our HACCP-based system identifies potential contamination points and implements preventive measures throughout the manufacturing cycle.
Final Product Testing
Every batch undergoes comprehensive heavy metal analysis before release. We maintain records for traceability, ensuring full compliance with regulatory requirements. For brands targeting international markets, we can arrange additional testing through accredited third-party laboratories.
