Product testing doesn’t take place exclusively within our two in-house labs, staffed with more than 50 highly trained, highly skilled scientists.
Young Living also utilizes third-party labs, working with more than a dozen of the world’s leading, independent, and accredited labs with highly skilled and trained scientists who specialize in advanced product testing.
Every essential oil at Young Living is tested for heavy metals like lead, arsenic, cadmium, and mercury. YL tests for a full range of microbial contaminants, including pathogens like e. Coli, Staphylococcus aureus, salmonella, and other possible organism contaminants (such as yeasts or molds), and agrochemicals.
Products categorized as dietary supplements or foods are tested for lead, arsenic, cadmium, and mercury.
