The Value of the NASC Seal on Your Horse’s Supplements!


As a Groom or horse owner, we are constantly learning about what goes into our horses in order to give them a better life with better health.  But how do we know we are making the right choices?  Often times, we don’t.  However, in the world of horse supplements, there is one way that you can gain some knowledge about a particular product.  Look for the NASC on your horse's supplements to make sure the ingredients listed are actually in the product in the amounts specified on the labels.  




Look closely - sometimes the NASC seal is small!

Selecting a supplement for your animal is an important decision. This process can be overwhelming with the sheer number of supplement manufacturers. How do you know the company is trust worthy? How do you evaluate the quality of their products? Are they following any kind of manufacturing or regulatory standards?

To address these questions,a group of manufactures organized and launch the National Animal Supplement Council in 2002. Quoting from the NASC website (; “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.” This group has shown great leadership in developing and enforcing a set of standards that all of the membership must follow. Only members that continually pass rigorous audits every two years can display the NASC seal.

What are the NASC standards and how were they developed? The NASC has worked closely with FDA and state agencies to develop these standards. The NASC standards are focused on four key areas.


  • Quality Control – An audited member must have a detailed Quality Control Program with written documentation of every step in the manufacturing process. This must include written SOP or Standard Operating Procedures that must be followed to comply. The strict quality control program is audited and helps insure members in compliance are producing consistent high quality products.
  • Adverse Event Reporting System - Each audited member must have an adverse event reporting system to monitor any and all adverse events reported about a product. The NASC does periodic testing of this system to insure their members are in compliance. This is valuable to you as an animal owner knowing any adverse event is being documented to help protect your animals.
  • Labeling Guidelines - Audited NASC members must follow strict guidelines for labeling. These standards set a “level playing field”. These standardized labels provide what is needed to make an informed decision without exaggerated claims or confusing terminology.
  • Warning and Caution Statements - Approved NASC labels must include warnings and caution statements recommended by the Food & Drug Administration’s Center for Veterinary Medicine and the NASC Scientific Advisory Committee for particular ingredients.
