Our commitment to quality is evident throughout the entire product development process. Before a single machine is turned on we carefully select vendors who supply premium raw materials. All vendors must provide a Certificate of Analysis for each raw material as a continued measure of quality. These certificates are then verified through random in-house and independent laboratory testing. Highly sophisticated equipment confirms the purity and potency of every ingredient on our labels. To further diminish any chance of physical, chemical, and microbiological contaminants, we have established and implemented our own Hazard Analysis Critical Control Point (HACCP) program. Quality assurance professionals make routine checks on all storage, blending, and production areas and conduct final inspections daily. Together, these procedures allow Optimum Nutrition to constantly deliver first-rate sports nutrition supplements under the strictest quality control standards known as current Good Manufacturing Practices (cGMPs).
