The NASC Quality Seal
Many pet owners today find they benefit from taking supplements and want their companion animals to experience these benefits as well. But when it comes to supplements, similar ingredients do not always mean similar quality. A side-by-side label comparison won’t tell you where ingredients were sourced or whether the supplier has a quality assurance and product testing program in place.
That’s where the NASC Quality Seal comes in.
Look for the yellow Quality Seal on supplements for dogs, cats and horses to know you’re buying from responsible suppliers that have successfully passed a comprehensive third-party audit and maintain ongoing compliance with rigorous NASC quality requirements.
