Healthy joints move easily because of a smooth, slippery joint cartilage. With age, loss of bone structure, increased brittleness and a decreased synthesis of joint cartilage affect bone joint health. Furthermore, overweight, vigorous exercise & sports may also cause injury to the joint, which may be painful and affect joint mobility and flexibility. HK Vitals Healthy Joints is an advanced supplement specifically formulated to improve joint mobility, flexibility, comfort, and strength. It also helps maintain bones strong and healthy.
