Good laboratory practices essential for supplement testing labs – podcast

Supplement testing labs that follow GLPs show a standard of quality that helps ensure reliable and consistent test methods, says lab expert Jen Johansen.

Good laboratory practices (GLPs) may not be legally required in full for supplement testing labs to follow in the U.S., but they are best practices that quality brands should demand of their contract lab partners. As Jen Johansen, vice president of quality, regulatory and government affairs, Cyanotech Corp., explains, GLPs are a set of principles and requirements for testing procedures, facilities, personnel, methods and references standards. GLPs are part of a larger quality system to ensure test results are reliable and consistent. While GLPs are not outlined in full in the dietary supplement regulations, sections of the mandated GMPs (good manufacturing practices) overlap with GLPs. In this podcast with Sandy Almendarez, editor in chief, Natural Products INSIDER, Johansen covers GLPs as well as:

  • Resources supplement brands can use to help them choose the best test methods and reference standards for their products
  • How brands must double-check their contract lab’s precision if the products will carry third-party certifications
  • How often to conduct—and what to look for during—a requalification of current testing lab partners.

Johansen is speaking at the SupplySide Workshop “Trust in Testing: Contract Labs for Safe, Compliant Supplements” on Thursday, Oct. 17 at  to 4 p.m. This session is underwritten by American Testing Lab, Eurofins Scientific, Micro Quality Labs Inc. and New Jersey Labs.
