Joint Relief is a natural joint support supplement. It contains active, bioavailable nutrients to support cartilage and optimize healthy joints. The product is largely made up of shark cartilage with naturally-occurring chondroitin sulfate and glucosamine sulfate, which help support and maintain structures that facilitate healthy joints.* Glucosamine and chondroitin are “raw material” nutrients for cartilage, connective tissues and lubricating factors within the joints. These natural compounds support the plump, cushy, hydrated “shock absorber” cartilage that is necessary for optimum joint health. Medicinal Ingredients: Shark Cartilage, Chondroitin sulfate. Non-Medicinal Ingredients: Hypromellose, magnesium stearate, titanium dioxide. Suggested Use: Adults: Take 4 capsules, 3 times daily. Take with meals and a glass of water. Must be taken regularly.
