Bones
How bones stay strong, who is at risk of bone loss and what helps at every age.
Bone is living tissue that is broken down and rebuilt throughout life. Bone mass builds through childhood and early adulthood. Later in life, and especially after menopause, bone loss happens more quickly than new bone is made. Calcium, vitamin D, protein and weight-bearing activity all help keep bones strong.
How it works
Vitamin D, converted in the liver and kidneys into its active form, calcitriol, helps the gut absorb calcium from food. Vitamin K is needed to activate proteins found in bone. Cells called osteoblasts build bone while osteoclasts break it down, in a balance influenced by hormones, physical activity and nutrition.
