Dietary Ingredients GMP Process Certification to 21 CFR 111 / 117 and NSF/ANSI 173, Section 8 – 2024


Dietary ingredients form the fundamental part of the quality and safety of dietary supplements which are highly regulated by FDA when manufactured in or exporting to the U.S. market. Choosing Good Manufacturing Practices (GMPs) certification is a proactive approach that demonstrates your dietary ingredients’ compliance to regulations, establishing stronger trust among buyers and consumers.
At Eurofins Assurance, we offer dietary ingredients GMP certification to important US regulations for food and supplement manufacturing, including 21 CFR Part 111, 21 CFR 121, 21 CFR Part 117 (Subparts A, B, & F), and 21 CFR Part 1 (Subpart L) and NSF/ANSI 173 – 2024 Section 8. This set of requirements ensures best practices in manufacturing traceability and documentation and helps ingredient manufacturers meet the needs of their regulated dietary supplements manufacturer customers.
Certifications requirements for dietary ingredients 21 CFR 111 / 117 and NSF/ANSI 173, Section 8 – 2024
Section 201(ff) (1) of the FD&C Act (21 U.S.C 321(ff) (1)) states a dietary ingredient is a vitamin; a mineral; an herb or other botanical; an amino acid; a dietary substance for use by man to supplement the diet by increasing total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of any of the above dietary ingredients.
There are no standards tailored for dietary ingredient manufacturing, which are regulated as food. Food regulations alone simply do not assure the level of traceability and documentation the dietary supplements industry depends on to mee their own strict regulatory requirements in the US market.
To fill this gap, Eurofins Assurance has developed a voluntary, custom protocol that is a blend of food and supplement regulations and best practices, to help ingredient manufacturers differentiate from the competition. Through this certification, ingredient manufacturers can show they have committed to implementing best practices and are prepared to support their customers regulatory compliance.
A GMP certificate of conformity and the Eurofins Assurance certification marks are issued to the company after all program requirements are met and the company is able to market its certification its customers and distinguish itself from competitors.
