Athletic dogs need additional nutrients to keep them running, hunting and jumping all day long. GlycoFlex Sport has been formulated to meet those needs. This formula includes Perna canaliculus, a green lipped mussel that naturally provides all of the nutrients that keep joints lubricated and cushioned. We also include glucosamine, MSM, Manganese and DMG. Manganese is an essential mineral that supports the formation of collagen and GAGS. These are necessary for supporting already present cartilage around the joint and may help to rebuild cartilage that is damaged during daily activity. DMG helps to manage inflammation in and around the joint while also providing the added benefits of better oxygen utilization and supporting focus and stamina.
