NASC-Certified Pet Supplement Brands
Pet supplements are certified by the National Animal Supplement Council (NASC) quality seal — a separate program from the human cert bodies. This section indexes the pet brands carrying that seal. Pick a brand to see its NASC certifications by species.
Browse by species
Grouped into tiers by the number of independent third-party certifications each brand holds (more bodies = higher tier). Within a tier, brands are ordered by how many of their products are certified, then by how recently each was verified, then Labdoor letter grade breaks remaining ties. This reflects only how thoroughly each brand is independently verified — not product quality, efficacy, or price, and not an endorsement.
