Current Good Manufacturing Practice Audit of Excellence

Salt Lake City (June 19, 2025) NSF^® International issued zero non-conformances and a certificate of confirmed compliance to 4Life following a recent quality, warehouse, and manufacturing audit. The NSF cGMP (current Good Manufacturing Practices) audit includes a rigorous evaluation of all manufacturing facilities, including multi-tiered inspections, in-depth process observation, and detailed accounting of all 4Life quality and production system records for verification of compliance with current Dietary Supplement Good Manufacturing Practices.

Steve Pederson, Senior Vice President Supply Chain—Quality & Analytical Services: “4Life is system solid and process proficient. Kudos to Phil Simonsen and Jerry Thomas, whose production and logistics teams keep our ship clean and tight. Props to Jim Dimmick and Jaden Turner’s QA and internal audit teams who illuminate the harbor. Finally, my hat is off to Javier Medina’s lab and QC teams who bring us safely to shore.”

In the United States, dietary supplement manufacturing facilities must be registered with the Food and Drug Administration (FDA) as food processing facilities. 4Life manufacturing facilities are held to the standards of U.S. Code Title 21 Part 111, which prescribes current Good Manufacturing Practices.
