Prop 65 Testing for Dietary supplements — Expert Lab Services
Expert prop 65 testing tailored for dietary supplements brands. Regulatory-compliant testing with COA documentation for product safety and market access.
Quick Answer
Prop 65 Testing for dietary supplements involves analyzing product samples using validated scientific methods to verify safety, purity, potency, and regulatory compliance. Accredited labs like Qalitex use instrumentation such as HPLC, ICP-MS, and microbiology assays to generate Certificates of Analysis (COA) required by FDA, Amazon, and retail partners.
Dietary supplements brands require specialized testing to ensure product safety, regulatory compliance, and consumer trust. Qalitex Laboratories provides prop 65 testing specifically designed for the dietary supplements industry. California Proposition 65 (Safe Drinking Water and Toxic Enforcement Act) requires businesses to provide warnings before knowingly exposing consumers to chemicals on the Prop 65 list. Qalitex Laboratories provides targeted Prop 65 testing to determine whether your products require warnings, protecting your brand from enforcement actions and consumer litigation. Our testing protocols are calibrated to the unique requirements of dietary supplements products, from raw material verification to finished goods release testing.
Prop 65 Testing Tailored for Dietary supplements
The dietary supplements industry has specific testing requirements driven by FDA regulations, marketplace compliance (Amazon, retail), and consumer safety expectations. Qalitex designs testing panels specifically for dietary supplements products, ensuring you meet all applicable standards while optimizing your testing budget. Our scientists understand the unique matrices and formulation challenges of dietary supplements products.
What Is Prop 65?
Prop 65 lists over 900 chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. The law applies to any product sold in California, regardless of where it is manufactured. Non-compliance can result in private attorney general lawsuits, fines up to $2,500 per day per violation, and mandatory warning labels.
What We Test For
We test for the most commonly cited Prop 65 chemicals in supplements and personal care products: Lead (MADL: 0.5 μg/day), Cadmium (MADL: 4.1 μg/day), Mercury (MADL: 0.3 μg/day), Arsenic (inorganic, NSRL: 10 μg/day), Acrylamide, Di(2-ethylhexyl)phthalate (DEHP), and Bisphenol A (BPA).
Safe Harbor Testing
If test results show your product's exposures fall below Prop 65 MADL or NSRL thresholds, you can sell in California without a warning label. Our testing reports include exposure calculations comparing results against Prop 65 limits, providing documentation for your safe harbor defense.
