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 maintain the very highest standards of quality.

UNCOMPROMISING QUALITY

Only raw materials of the highest quality are selected for Optimum Nutrition products, each one requiring certification to substantiate origin, biological make-up and conformance to food safety standards. Upon arrival at our manufacturing facility raw materials undergo further rigorous inspection & testing by our experienced quality assurance team to satisfy us that every ingredient meets our own exacting standards prior to release for production. Throughout the manufacturing process, our teams measure and record against multiple quality control points to deliver high standards of product quality & integrity at all times. Our Quality Assurance team add a further layer of independent inspection and auditing to assure Goods Manufacturing Practices (GMP) are sustained to provide end-to-end compliance with the Food Standards Agency (FSA) regulations and related legislation.

We’re proud to be a certified Informed Manufacturer, making us part of a global quality assurance program operated by LGC for facilities that manufacture and supply sports nutrition products and ingredients, developed to manage the risk of banned substance contamination.

It is for all of these reasons that Optimum Nutrition is the preferred Performance Nutrition supplier to England Rugby, the English Institute of Sport, The ECB, Saracens, Munster & Leinster rugby clubs, as well as many more top-flight sporting entities and individuals around the world.
