Optimum Nutrition

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).
