The Journey from Raw Material to Finished Product

AOR's manufacturing process is a multi-step journey focused on precision and quality, transparently outlined by the company.

Step 1: Ingredient Sourcing

While manufactured in Canada, AOR sources premium raw materials globally from a network of suppliers in locations such as Europe, India, and China. Suppliers must provide documentation detailing origin and compliance.

Step 2: In-House Formulation and Testing

Upon arrival, raw materials are tested for identity, potency, and purity, including heavy metals and pesticides, at the Calgary facility. Verified ingredients are then used to formulate supplements based on scientific research and orthomolecular principles.

Step 3: Manufacturing and Processing

AOR manufactures products in-house, ensuring control over the final product. Manufacturing follows Canadian Good Manufacturing Process (cGMP) standards and internal quality assurance measures.

Step 4: Third-Party Testing and Quality Control

Finished products are sent to third-party, ISO-certified laboratories for independent testing of purity, potency, stability, and safety. This verification confirms product claims.
