Why Heavy Metal Testing Matters for Supplement Brands

At SREKE, we understand that heavy metal contamination poses a serious risk to consumer safety and brand reputation. As a GMP-certified dietary supplement OEM/ODM manufacturer based in Guangzhou, China, we prioritize rigorous testing protocols to ensure every product meets international safety standards.

Regulatory bodies such as the FDA (USA), EFSA (Europe), and Health Canada require strict limits on lead, cadmium, mercury, and arsenic in dietary supplements. Our compliance with USP <730>, ISO 17025-accredited lab testing, and HACCP protocols ensures our clients can confidently launch products that pass customs inspections and retail audits.

Key Manufacturing Considerations at SREKE

• Raw Material Screening: All incoming ingredients undergo third-party heavy metal analysis before production begins.
• In-Process Controls: We monitor critical control points during blending and encapsulation to prevent cross-contamination.
• Finished Product Testing: Each batch is tested by accredited labs for heavy metals, microbiology, potency, and stability.
• Traceability: Full batch documentation is maintained for audit readiness, including COAs (Certificates of Analysis) from certified laboratories.
• GMP Certification: Our facility complies with Chinese GMP, WHO-GMP, and EU-GMP standards, supporting global market access.

Industry Trends and Market Opportunities

Consumers are increasingly demanding transparency about supplement purity. According to a 2023 Consumer Reports survey, over 68% of buyers check for third-party testing before purchasing. Brands that proactively publish heavy metal test results gain significant trust advantages.

Additionally, the global heavy metal-free supplement market is projected to grow at 7.2% CAGR through 2030 (Grand View Research, 2023). By partnering with a manufacturer like SREKE—where every batch includes verified heavy metal testing—you position your brand ahead of competitors who cut corners on safety.

Frequently Asked Questions

Do you test for all four regulated heavy metals?

Yes. At SREKE, we routinely screen for lead, cadmium, mercury, and arsenic using ICP-MS (Inductively Coupled Plasma Mass Spectrometry) methods aligned with USP <730> and ISO 17025 standards.

Can you provide test reports for my customers?

Absolutely. We generate batch-specific Certificates of Analysis (COAs) that include heavy metal results. These can be shared directly with retailers, distributors, or included in digital product pages.

What if my supplier’s raw materials fail testing?

Our quality team will immediately flag non-conforming materials. We work with approved alternative suppliers and rerun tests before any production resumes—ensuring no compromised ingredients enter your formula.

Do you support private labeling and custom packaging?

Yes. We offer full private-label services, including custom bottles, blister packs, boxes, and labels designed to meet regional labeling laws (e.g., FDA in the U.S., FIC Regulation in the EU).
