National Animal Supplement Council (NASC)

The National Animal Supplement Council (NASC) is a nonprofit trade association dedicated to promoting the health and well-being of companion animals and horses that receive animal health and nutritional supplements.

NASC Preferred Suppliers are trusted vendors of raw materials, contract manufacturing, analytical laboratory services, packaging, and other essential products and services. Each Preferred Supplier undergoes a rigorous vetting process to ensure compliance with NASC’s industry-leading quality standards.

Because of this, NASC members who supply finished products can rely on Preferred Suppliers without needing additional vendor qualification procedures under NASC cGMPs. The blue NASC Preferred Supplier logo identifies companies that have earned this designation, helping ensure confidence and quality throughout the supply chain—from raw materials to finished products.
