Optimum Nutrition

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)

History of 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 recently launched the game changing Protein Whipped Bites the new on-the-go protein snack.
