Optimum Nutrition

optimum nutrition



Optimum Nutrition, Inc. (ON) is a wholly owned subsidiary of Glanbia, a leading international cheese and nutritional ingredients group. ON owns and operates two premium sports nutrition brands, Optimum Nutrition and ABB Performance, providing a comprehensive line of products across multiple categories.

With state-of-the-art production facilities in three states, ON is the only sports nutrition company to manufacture items in every product category. Whether it's nutritional bars, protein powders, ready-to-drink shakes and energy formulas, or vitamins and minerals, Optimum Nutrition takes a hands-on approach to maintaining the very highest standards.


Optimum Nutrition was established in 1986 to satisfy consumer demand for consistent quality in sports nutrition. The company is also known for innovation, being first to produce a casein protein powder, and first to offer an all-micellar casein formula. ON's industry leadership can also be seen in the dominance of Gold Standard 100% Whey, universally recognized as the world's best-selling whey protein.

Mission Statement

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.

Quality Counts

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).

Customer Satisfaction

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.

Where You Can Find Us

Our products can be found throughout the United States in close to 10,000 independent natural product and specialty retail stores, gyms, and fitness centers, and several major grocery chain and drug stores. You can also find us at most on-line retailers, as well as throughout the world with current distribution in over 70 countries.
