Quality Assurance & Quality Control

Lief dedicates 25% of its staff to Quality Assurance & Quality Control. All of our products are produced in the United States and manufactured in accordance to the latest FDA cGMP guidelines and in compliance with 21CFR Part 111.

Our team only sources quality ingredients from trusted suppliers who have been approved through our internal qualification process. In addition, Lief performs tests to certify and validate that nutrition facts and vitamin & mineral label claims are met and other hazardous elements, such as microorganisms, are not present. These tests are conducted on each raw material and all finished products. Testing is performed both internally and by reputable, qualified third party laboratories that have experience testing dietary supplements and understand our unique product requirements.

Lief Labs’ Quality Control laboratory has been recognized by A2LA – ISO/IEC 17025 accredited body for microbiological testing. Working in partnership with A2LA Accreditation, Lief Labs confirms and demonstrates our ongoing commitment in doing our part to ensure public safety by providing high standards of testing and quality assurance backed by exceptional competency.
