About Optimum Nutrition
Optimum Nutrition, Inc. (ON) was founded in 1987 by two brothers, Tony and Michael Costello. Originally known as Costello's Health Distributors, the entrepreneurial brothers soon recognised an opportunity to significantly improve quality and innovation in the sports nutrition industry. Their mission was to provide innovative products of consistently high quality to active adults the world over. The company is now part of Glanbia, a leading international cheese and nutritional ingredients group.
Optimum Nutrition, Inc. (ON) is a range of sports nutrition products which offer premium quality ingredients that taste great. With state-of-the-art production facilities, ON manufacture an award-winning range of nutritional bars, protein powders, ready-to-drink sports drinks, vitamins and essential minerals.
Our commitment to quality is evident throughout the entire product development process, making sure that each product contains the highest quality ingredients for maximum results. Before a single machine is switched on we carefully select the suppliers who provide our premium raw materials. All suppliers must provide a Certificate of Analysis for each raw material as a continued measure of quality.
These certificates are then verified through in-house and independent laboratory testing. Highly sophisticated equipment confirms the purity and potency of every ingredient on our labels. 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 consistently deliver first-rate sports nutrition supplements under the strictest quality control standards.
Ever since the Costello brothers set up ON in 1987, our customers have been our number one priority and always will be. While strict quality control, lab testing and manufacturing under tightly controlled conditions are very important, they are all done for one reason - to bring you premium quality supplements. We pride ourselves on our customer loyalty.
ON's product range, renowned for its variety of great tasting flavours and ease of mixing, includes the world's best selling protein combination of Gold Standard 100% Whey and Casein. All the products have been specifically developed to deliver superior technology to ensure that consumers achieve their goals.
Top sports stars trust Optimum Nutrition to help them achieve their goals and reach their full potential. Optimum Nutrition is the Official Sports Nutrition partner to 2009 Heineken Cup champions Leinster, Northern Irish side Ulster and Championship team The Cornish Pirates.
