Optimum Nutrition, Inc. (ON) is part of the Glanbia global nutrition group and has been setting the Gold Standard in sports nutrition for more than 30 years - helping performance-focused athletes achieve their goals.
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 maintain the very highest standards of quality. 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.
Before a single machine turned on in ON 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. 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. Optimum Nutrition Company founded with a mission to bring consistent quality to the marketplace, and they are constantly working on setting even higher standards.
