Supports the body's bones, joints & muscles

Structural system support The structural system provides the framework for our body, protects our organs, houses marrow, and store minerals. Bones, joints, tendons, ligaments, muscles, and teeth allow us to move freely and perform tasks. Age, lack of exercise, a poor diet and other factors may contribute to an unhealthy structural system, which may result in limited range of motion. The ingredients in this 30-day Structural System program are formulated to supply nutrients to help maintain strong bones and healthy structural tissue.
