Heavy Metal Free: Certificates Provided Per Batch – Tianzhong Kangyuan Guarantees Purity
Recent FDA recalls underscore the critical importance of heavy metal testing. In March 2025, New York Wholesale Group recalled multiple herbal products due to elevated lead and arsenic levels detected by Connecticut regulators . Short-term lead exposure may be asymptomatic, but chronic exposure is associated with kidney dysfunction, hypertension, and increased cardiovascular mortality risk . Inorganic arsenic exposure has been linked to cancer, skin lesions, and neurodevelopmental effects in children . Tianzhong Kangyuan Pharmaceutical Group Co., Ltd. eliminates these risks through per-batch heavy metal testing with Certificates of Analysis provided for every shipment.
The Science of Heavy Metal Testing for Dietary Capsules
Dietary Capsules must comply with USP General Chapter <2232>, which establishes Permitted Daily Exposure limits for the four major toxicological elements: arsenic, cadmium, lead, and mercury . Testing requirements shifted fundamentally on January 1, 2018, when USP officially omitted the outdated General Chapter <231> Heavy Metals colorimetric method and adopted modern instrumentation requirements . Current compliance demands ICP-MS or ICP-OES analysis meeting USP <232> limits and <2232> specifications for dietary supplements . Our laboratory validates every vitamin e dietary supplement batch against these stringent thresholds, ensuring your nutrition vitamins supplements contain no detectable arsenic, cadmium, lead, or mercury above permitted levels.

Each batch of Dietary Capsules undergoes comprehensive screening that meets or exceeds USP <2232> requirements .
