Nutramax Cosequin Joint Supplement for Dogs vs VetriScience GlycoFlex 2 Hip and Joint Chews

Both are solid glucosamine joint supplements, but they serve different dogs. Cosequin is the safer default: it is the brand most veterinarians name first, it has a large, strong owner rating, and its formula is simple and well studied. GlycoFlex 2 adds green-lipped mussel, DMG and manganese for moderate joint support, and its hydrolyzed chicken chew suits dogs with protein sensitivities. Choose Cosequin for a first joint supplement or a picky large dog; choose GlycoFlex 2 if your vet wants a stage-2 formula or your dog reacts to standard proteins.

• Choose the Cosequin if you want the most widely vet-recommended joint supplement with a long track record and a simple glucosamine, chondroitin and MSM formula.
• Choose the GlycoFlex 2 if your dog needs moderate, stage-2 joint support and you want green-lipped mussel, DMG and a hydrolyzed chicken chew that suits sensitive stomachs.
