What heavy metal testing and certification mean
Eight metals. One published standard. Independently tested.
The Heavy Metal Certified mark means a product was evaluated against a published standard and tested through a qualified independent laboratory. The mark does not mean a product is safe, clean, or free of metals. Heavy Metal Certified is not a laboratory. This site explains the mark. The standard itself is published on Heavy Metal Certified.
Detection is not the same as risk. Modern instruments find metals at parts per trillion. What matters is the amount per daily serving, measured the same way every time.
QUANTIFIED BY ICP-MS AT INDEPENDENT LABS
Every seal stands on published science.
Heavy Metal Certified is built on the Heavy Metal Index, an open research library covering contamination, remediation and toxicology across the food and supplement supply chain. Read it before you trust the mark.
What testing and the mark mean
A published standard
Heavy Metal Certified publishes what is measured and how a product is evaluated. This site does not host that standard.
Independent laboratory testing
A qualified laboratory measures lead, arsenic, cadmium, mercury, chromium, nickel, tin, and aluminum. A result is a measurement, not a verdict.
A mark with limits
The seal is licensed to products that conform to the published standard. It does not mean safe, clean, or zero metals.
