There are 206 bones in the average adult body, and all but one are joined to at least one other bone. It’s not like a bone resting directly against another one either—they need protection. This protection comes from our joints, which act as a meeting point or cushion between our bones.

Synovial joints, or moving joints, are highly engaged during exercise. They account for 90 percent of all joints in the body, and they’re made up of bone, cartilage, tendons, ligaments, and synovial fluid. Synovial fluid is important because it helps to increase cartilage density and elasticity.

Taking your Procosa® is a great way to start taking care of your joints!
