Quick Answer
Heavy Metal Testing in California is available through ISO 17025 accredited laboratories like Qalitex Labs, which operates facilities in Irvine and San Diego, California. These labs use validated analytical methods including HPLC, ICP-MS, and GC-MS to test dietary supplements, cosmetics, and food products for safety, purity, and regulatory compliance.
FDA Warns of Elevated Lead Levels in Dietary Supplement Products
The FDA issued safety warnings after detecting elevated lead concentrations in multiple supplement brands sold online, underscoring the need for independent third-party heavy metal testing before launch.
Qalitex Laboratories provides ISO 17025 accredited heavy metal testing services to brands in California and throughout the United States. If you make or sell dietary supplements, food or cosmetics, a heavy metal test is usually one of the first lab reports a buyer, retailer or regulator asks for. Qalitex runs heavy metal testing by ICP-MS for dietary supplements, food products and cosmetic formulations, with experienced chemists and documented protocols, so you know what is in your product and whether it meets the limit that applies. Our California-area clients benefit from proximity to our Southern California labs, enabling faster sample delivery and turnaround times as quick as 48 hours.

How do you test a product for heavy metals?
You send a representative sample of the finished product or raw ingredient to an accredited laboratory. The lab prepares the sample so the metals are dissolved in solution, measures each metal by ICP-MS, checks the run against quality controls, and reports a result for every metal. You then compare the result with the limit that applies to your product and market. If you are not sure which panel or method fits your product, ask before you ship the sample.
Why heavy metal testing is critical
Heavy metals like arsenic, lead, cadmium and mercury are toxic even at low concentrations. They can contaminate ingredients through soil, water, processing equipment and packaging. Regulators set limits to prevent harm such as neurotoxicity, kidney damage, developmental delays and carcinogenicity, and a failed or missing test can stop a product from being sold.
Heavy metals in supplements, food and cosmetics
Botanical and mineral ingredients, plant-based powders and extracts, and products made on metal equipment are common places for metals to show up, which is why testing is routine for dietary supplements and their raw materials. The same four metals matter in food and in cosmetic formulations. Testing the raw material and the finished batch can show where a problem enters.
