Move Free Advanced is a Glucosamine Chondroitin joint supplement that contains premium ingredients, including glucosamine, chondroitin, uniflex (calcium fructobrate), and hyaluronic acid, to promote the health of your joints. Glucosamine is key for the formation of cartilage, an essential building block of your joints to support your mobility and flexibility.* Chondroitin is a building block of cartilage that supports joint strength by helping to resist compression in the joint. Chondroitin attracts fluid to your joints to support cushioning and lubrication.* Uniflex (calcium fructobrate) is a clinically test mineral complex that supports joint comfort in as little as 2 weeks.** Hyaluronic Acid is the same molecule found in healthy joint fluid that supports joint lubrication and smooth movement. As we get older, our levels of HA tend to decrease.
