About

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.

COMPANY OWNED & OPERATED MANUFACTURING

With state-of-the-art production facilities in Middlesbrough, UK, Optimum Nutrition 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 maintaining the very highest standards of quality.

UNCOMPROMISING QUALITY

Before a single machine is turned on in our manufacturing facilities, Optimum Nutrition 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. The Plant is also Informed Sport and Informed Choice registered and retains a Grade A BRC food Certificate. Optimum Nutrition is a Preferred Supplier to the English Institute of Sport (EIS)

DRIVING CATEGORY INNOVATION

In addition to making Gold Standard 100% Whey the world’s best-selling whey protein powder, Optimum Nutrition created the slowly digesting protein category with Gold Standard 100% Casein. Optimum Nutrition also created the anytime energy category, which remains dominated by Essential Amino Energy, and launched the Optimum Protein Bar and the Protein Crisp Bar, the perfect on-the-go protein snacks.

CUSTOMER SATISFACTION

Optimum Nutrition’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. Our company was founded with a mission to bring consistent quality to the marketplace, and we are constantly working on setting even higher standards.

WHERE YOU CAN FIND US

Our products can be found throughout the United Kingdom in specialty retail stores, gyms and fitness centres as well as major grocery chains and online retailers and of course here direct from the brand you trust. Optimum Nutrition’s products are available across the globe.
