After age 30, bone mass, muscle strength, and joint flexibility naturally decline, with bone loss occurring annually. Maintaining these requires a multi-faceted approach beyond just calcium and vitamin D. Nutrients like magnesium, crucial for over 300 bodily functions including bone mineralization and energy, and vitamin K2, which supports heart and bone health, are vital. Glucosamine also aids joint health. These nutrients work synergistically to support overall well-being and daily living as individuals age.
