Overview
UL Solutions (formerly Underwriters Laboratories) is a global safety science company that operates an FDA-registered dietary supplement testing laboratory in Canton, Massachusetts. UL technicians use industry-approved methodologies including DNA testing for botanical identity verification, potency analysis, and contaminant screening for heavy metals, pesticides, and microbial hazards. UL offers a Dietary Supplement Verified Mark program; brands that participate and qualify can display the UL Verified mark on their products, providing third-party verification of quality and label accuracy. NOW Foods is a notable brand that holds UL dietary supplement certification. UL has been in operation since 1894 and employs over 15,000 people worldwide. Their supplement testing division is smaller relative to their electrical safety and consumer product testing businesses, but carries the weight of a globally recognized certification mark.
