Optimum Nutrition, Inc. (ON) is a wholly owned subsidiary of Glanbia, a leading international cheese and nutritional ingredients group. ON owns and operates two premium sports nutrition brands, Optimum Nutrition and ABB Performance, providing a comprehensive line of products across multiple categories.
Our commitment to quality is evident throughout the entire product development process. Before a single machine is turned on we carefully select vendors who supply premium raw materials. All vendors must provide a Certificate of Analysis for each raw material as a continued measure of quality. These certificates are then verified through random in-house and independent laboratory testing. Highly sophisticated equipment confirms the purity and potency of every ingredient on our labels. To further diminish any chance of physical, chemical, and microbiological contaminants, we have established and implemented our own Hazard Analysis Critical Control Point (HACCP) program. Quality assurance professionals make routine checks on all storage, blending, and production areas and conduct final inspections daily. Together, these procedures allow Optimum Nutrition to constantly deliver first-rate sports nutrition supplements under the strictest quality control standards known as current Good Manufacturing Practices (cGMPs).
Please note that site registration does NOT mean that finished products have been tested. The Informed-Sport site registration does not involve any finished product testing, only that the site has committed to an ongoing audit and swab testing in order to minimise cross contamination of WADA prohibited substances.
