Optimum Nutrition (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 (ABB). Together, these brands provide active adults around the world with a comprehensive line of powdered, bar, tablet, capsule and ready to drink products.
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 GMP Registered and GMP for Sport by NSF.
In addition to making Gold Standard 100% Whey Protein powder, 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.
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. The company was founded with a mission to bring consistent quality to the marketplace, and they are constantly working on setting even higher standards.
