As a California-based ISO 17025 accreditation pending laboratory, we understand the state-specific compliance requirements that affect supplement brands operating in California — including Proposition 65 heavy metals thresholds, California Department of Public Health cGMP requirements, and the disclosure obligations that have made California one of the most demanding supplement markets in the US.
California has the strictest supplement-related regulations in the US. Proposition 65, California's Safe Drinking Water and Toxic Enforcement Act, imposes exposure disclosure requirements that are often more stringent than FDA's national standards.
Any supplement sold in California must meet Prop 65 safe harbor thresholds for lead, cadmium, arsenic, and mercury — or display a warning label. ICP-MS testing is the standard documentation method.
Whole Foods, Sprouts, and other California natural food retailers require third-party testing COA as a condition of listing. Our COA format satisfies documentation requirements across all major California accounts.
Amazon's Prop 65 enforcement focuses heavily on products shipped to California customers. Proactive ICP-MS testing documentation reduces the risk of listing suspension.
California Prop 65 private enforcement actions — served by plaintiff's attorneys on behalf of the public — target supplement brands without adequate testing documentation. Our COA provides the analytical defense.
California's agricultural environment and global ingredient sourcing create metal contamination risk in botanical supplements. State-specific compliance requires California-aware testing protocols.
We include California-specific regulatory reference values — Prop 65 MADL and NSRL thresholds — on all COAs for clients selling in California.
