Good Health Joint Active combines three powerful ingredients into an easy to swallow 1-a-night small capsule. UC-II® is a unique patented form of Type II undenatured collagen that works with the immune system to preserve joints and to support the regeneration and maintenance of healthy cartilage. Boron is essential for healthy bones and Vitamin D supports optimal cartilage production. Joints receive nutrients through adjoining bones – so healthy bones are key for healthy joints.
