Optimum Nutrition, Inc. (ON) is part of Glanbia, a leading international cheese and nutritional ingredients group. ON owns and operates two premium sports nutrition brands, Optimum Nutrition and American Body Building (A.B.B.). Together, these brands provide active adults around the world with a comprehensive line of powdered, bar, tablet, capsule and ready to drink products.
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.
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 (cGMPs) compliant facilities, which are Certified for Sport by NSF.
In addition to making Gold Standard 100% Whey, the worlds' best-selling whey protein, ON created the slowly digesting protein category with Gold Standard 100% Casein. ON also created the anytime energy category, which remains dominated by Essential Amino Energy.
