NASC Quality Seal

The Probios® Soft Chews and Tablets proudly wear the NASC Quality Seal. The seal on each jar of supplements is a signal to pet parents that the contents have been manufactured in an audited facility that meets rigorous quality standards. Our products adhere to NASC labeling guidelines so it’s clear what is in each package.

NASC (National Animal Supplement Council) is an industry organization dedicated to the health of companion animals. NASC conducts audits of production facilities and maintains labeling standards across the nutritional supplement industry so pet parents can trust the quality and safety of the products they purchase for their pets.
