Our bones and joints play a critical role in our musculoskeletal system, a network that includes our muscles, ligaments, tendons and other connective tissue. It is well established that as a consequence of normal aging, we see many changes in the musculoskeletal system that can lead to decreased mobility and quality of life. Decreases in bone density, changes in cartilage and connective tissue and altered muscle function can all occur as part of the normal aging process. Changes in muscle function are also observed as a part of normal aging. Fortunately, a healthful diet, exercise and proper supplementation can help us maintain healthy mobility and an active lifestyle well into our later years.^‡
