California Compliance Requirements

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.

🌅

Proposition 65

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.

🏛️

California Retailers

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 California Enforcement

Amazon's Prop 65 enforcement focuses heavily on products shipped to California customers. Proactive ICP-MS testing documentation reduces the risk of listing suspension.

⚖️

60-Day Notice Litigation

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.

🌿

Botanical Ingredient Risk

California's agricultural environment and global ingredient sourcing create metal contamination risk in botanical supplements. State-specific compliance requires California-aware testing protocols.

🔬

State-Specific Reporting

We include California-specific regulatory reference values — Prop 65 MADL and NSRL thresholds — on all COAs for clients selling in California.
