With state-of-the-art production facilities in Aurora, Illinois; Walterboro, South Carolina and Sunrise, Florida, ON is one of the few sports nutrition companies to manufacture in every product category. From the very beginning in 1986, Optimum Nutrition has always taken a hands-on approach to maintaining the very highest standards of quality.

Optimun Nutrition was the first brand to introduce casein protein in the supplementation and fitness world and the first to introduce the micellar casein formula. However, leadership is due to the success of its top product 100% Gold Standard, considered to be the best whey protein concentrate in the world. This product has been winning the "Protein Powder Of The Year" and "Supplement Of The Year" awards since 2005.

Through a very organised and complete structure, the Optimum Nutrition team works in a perfect coordination and flexibility to meet the consumer's needs.

Optimum Nutrition has removed a great part of intermediaries and they now control their integrity through the whole process of manufacture and distribution.

Quality control

Before a single machine is turned on in our manufacturing facilities, ON procurement professionals carefully select the most premium raw materials. A Certificate of Analysis is required for every ingredient, which is then tested and retested for compliance. Quality assurance performs daily inspections of our current Good Manufacturing Practices (GMPs) compliant facilities, which are Certified for Sport by NSF.

ON's strict ingredients selection, quality control, lab testing and manufacturing processes are all done for one reason: to provide you with the highest quality sports nutrition products available. Our company was founded with a mission to bring consistent quality to the marketplace, and we are constantly working on setting even higher standards.
