NOW's Top 50

NOW® is committed to quality and safety through a comprehensive testing program. Historically, we conducted about 19,000 tests per month to assess various aspects of product quality, including raw materials, in-process samples, and finished goods. Since 2023, we have increased our monthly quality testing from 19,000 to 31,000. This expansion is driven by enhanced analytical and microbiological testing, with a particular emphasis on allergen detection and environmental monitoring.
