Optimum Nutrition believes you get out what you put in – which is why our certified manufacturing facilities only use high-quality ingredients and strict quality control when making our products.
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 and GMP for Sport by NSF.
