NASC Audit Program


The National Animal Supplement Council is a non-profit industry group dedicated to protecting and enhancing the health of companion animals and horses throughout the United States. NASC was formed in 2001 when the multibillion dollar animal health supplement industry was threatened by a complicated and erratic regulatory environment.

As part of its ongoing effort to improve and standardize the animal health supplement industry, NASC initiated its Quality Seal Program. The Seal is a way for consumers to know that when they buy a product, they buy from a reputable company that has successfully completed a facility audit. Different from the NASC logo, use of the Seal is a privilege for members and signifies that the company has been audited for the implementation of specific standards.

NASC members must agree to adhere to NASC’s quality standards which include submitting to an independent audit to ensure conformance with quality system requirements.

NASC member companies are required to demonstrate compliance with the following criteria before they are granted permission to display the Seal on their products, websites, product literature and advertisements:

  1. The company must have a Quality Control Manual in place that provides written Standard Operating Procedures for production process control. This helps ensure the company is providing a consistent and quality product.
  2. The company must have an Adverse Event Reporting/Complaint System in place to continually monitor and evaluate products and ingredients.
  3. The company must follow proper Label Guidelines for all products and all forms of labeling.
  4. The company’s product labels must include any specific Warning and Caution Statements recommended by the Food & Drug Administration’s Center for Veterinary Medicine and the NASC Scientific Advisory Committee for particular ingredients.

Veterinarians and veterinary technicians should look for the NASC Quality Seal. Purchasing products from NASC members is the best way you can support efforts to improve the quality of animal health supplements and ensure the continued availability of these products in the US market.
