Our musculoskeletal system is often subjected to strain; in many cases this is also accompanied with overweight, unilateral strain or overloading. Moderate exercise and a well-balanced diet help to preserve the functions of the musculoskeletal system. Manganese contributes to the normal formation of connective tissue and, like Vitamin D, contributes to the maintenance of normal bones. Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones.
