Optimum Nutrition, Inc. (ON) is a wholly owned subsidiary of Glanbia, a leading international cheese and nutritional ingredients group. ON owns and operates two brands of nutritional supplements (Optimum Nutrition and American Body Building) providing a comprehensive line of products across multiple categories. With state-of-the-art production facilities occupying over 500,000 square feet of operating space, ON is the only sports nutrition company to manufacture items in every product category. Whether it's nutritional bars, protein powders, ready-to-drink sports beverages, or vitamins, essential minerals, and herbs, Optimum Nutrition is able to control the integrity of all products through in-house manufacturing. Supported by Costello's Health Distributors (Optimum Nutrition's sister distribution company) and ABB's nationwide direct service distribution network, customers are ensured prompt delivery and unmatched customer support.
Collectively, Optimum Nutrition, American Body Building, and Costello's Health Distributors, are the dominant force in the sports nutrition industry with the highest quality products available in health food stores, specialty stores, gyms and progressive retailers everywhere.
Optimum Nutrition was founded in 1986 by brothers Tony and Michael Costello. Originally known as Costello's Health Distributors, the entrepreneurial brothers soon recognized an opportunity in the need for significantly improved quality and innovative vision in the sports nutrition industry. The Optimum Nutrition brand was launched to satisfy both demands, and after 22 years of success reflected in great part by the ongoing best-selling status of ON Gold Standard 100% Whey, the Costello's entered into agreement to sell the company to the international cheese and nutritional ingredients group Glanbia.
Optimum Nutrition strives to produce distinctive, affordable, premium-quality products while making every effort to anticipate ever-changing customer needs and meet the demands of a dynamic market with innovative products, effective support materials, and unsurpassed service.
As an advocate of healthy lifestyles, ON believes that every consumer should be able to purchase premium products; so we eliminate the middlemen and control the integrity of our brand throughout the entire production and distribution processes… making sure each product is not just top quality, but also among the most competitively priced in the industry.
Our commitment to quality is evident throughout the entire product development process. Before a single machine is turned on we carefully select vendors who supply premium raw materials. All vendors must provide a Certificate of Analysis for each raw material as a continued measure of quality. These certificates are then verified through random in-house and independent laboratory testing. Highly sophisticated equipment confirms the purity and potency of every ingredient on our labels. To further diminish any chance of physical, chemical, and microbiological contaminants, we have established and implemented our own Hazard Analysis Critical Control Point (HACCP) program. 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 constantly deliver first-rate sports nutrition supplements under the strictest quality control standards known as current Good Manufacturing Practices (cGMPs).
From the beginning, our customers have been our number one priority. While strict quality control, lab testing, and manufacturing under tightly controlled conditions are all very important, they are all done for one reason – to bring you high quality, affordable supplements. We pride ourselves on customer loyalty and are pleased to report that nearly all of our first-time customers become devoted patrons. You can be confident that from the moment a product is conceived to the moment it leaves our facility we put only the best into Optimum Nutrition so you only put the best into your body.
