Overview

Glycoflex 3 is VetriScience's maximum-strength hip and joint chew, layering glucosamine with MSM, green lipped mussel and DMG in a 120 count bottle.

The number 3 marks this as the top tier of the Glycoflex line, adding ingredients beyond a base glucosamine product. It suits dogs with more advanced joint needs rather than a young dog on general maintenance.
