Our read
Two of the highest-scoring cat joint supplements, tied on composite. In our view Dasuquin for Cats edges active dose and a slightly cleaner label, while GlycoFlex Plus for Cats answers with a stronger safety-and-manufacturing mark. Evidence and value are level. A coin flip between two well-made feline joint chews.
This verdict is our opinion under the PetScored rubric, not veterinary advice. The exact sub-scores are in the table below; each product’s source confidence and limitations stay on its own scorecard.
Nutramax
A fully-disclosed glucosamine, chondroitin, and ASU joint capsule for cats at the studied forms and a weight-scaled dose; the active's osteoarthritis evidence is contested and Nutramax is not an NASC member, so it lands Good rather than Strong.
VetriScience
A fully disclosed, per-ingredient cat joint chew from a NASC, own-facility maker, with green-lipped mussel alongside glucosamine and chondroitin and a hedged support claim; the catch is the same as every glucosamine product, the evidence for the active is weak and contested, so it lands Good on execution rather than Strong on proof.
Comparison scores use the same reconstructed score-event math as the supplement scorecards. Source confidence, unresolved gaps, evidence-library citations, and dose caveats remain attached to each individual scorecard.
