Does GlycoFlex® actually work for dogs?

Not only do we have thousands of happy customers who love using GlycoFlex® for their dogs, GlycoFlex® Stage 3 is clinically proven to increase hind leg strength by up to 41% in just four weeks!* This formula for medium and large dogs is made with green-lipped mussel, glucosamine, MSM, and other beneficial nutrients to support hip & joint health and mobility. Hydrolyzed chicken flavor is appropriate for pets with sensitivities to protein.

Your dog can also enjoy the benefits of advanced joint support in GlycoFlex® Stage 3 Chewable Tablets, which may be suitable for sensitive stomachs. For our smaller canine friends, consider GlycoFlex® Stage 3 for Small Dogs (under 30 pounds). Its the same powerful recipe but formulated specifically for small-breed dogs.

What is the difference between GlycoFlex® and GlycoFlex® Plus?
Understanding pet joint health is key to understanding joint supplement ingredients and their strength. A wider variety of active ingredients + higher levels of those active ingredients = a more powerful supplement.

Ingredient Highlights

GlycOmega™ Green-Lipped Mussel (Perna canaliculus) is the foundation of our formula and nature’s perfect blend for joint support. This New Zealand mussel is a whole-food organism and a natural source of chondroitin and glucosamine as well as hyaluronic acid, antioxidants, and omega-3 fatty acids. 

Glucosamine Hydrochloride (HCl) is a critical nutrient for building healthy connective tissue and is one of the foundational compounds in cartilage. GlycoFlex® Plus uses only the highest quality forms of glucosamine from sources like shrimp & crab, which are some of the only natural sources of this nutrient. Some other joint supplements use synthetically produced glucosamine, which may not be as well-absorbed by the body.

MSM (Methylsulfonylmethane) is a sulfur compound found naturally in your dog's body that supports the structure of joints and connective tissue, as well as many bodily processes including collagen synthesis. Manganese also supports the formation of collagen, which is required for optimal cartilage structure and integrity.

Chondroitin Sulfate is a natural component of your dog's connective tissue. It's added to our clinically proven GlycoFlex® formula to help support the structure and integrity of those tissues by absorbing fluids into existing cartilage and providing the building blocks for new cartilage. This helps to promote joint flexibility and overall mobility & comfort. 

DMG (N-N-Dimethylglycine) supports your dog's overall comfort and performance by supporting blood circulation, efficient oxygen utilization, and energy.

Vitamins E & C, Selenium, and L-Glutathione provide antioxidant support to promote free-radical-scavenging activities. Grape Seed Extract (Vitis vinifera) is another powerful antioxidant that can support blood flow and healthy joints.

Storage instructions: Store in a cool, dry place.
