Bone is a living tissue that continually remodels itself during life. Some bone cells absorb bone tissue, while others re-form the bone's surfaces. Normally, these processes are well balanced. A person's peak bone mass occurs at about the age of 35. After age 35, it's important to continue a calcium-rich diet and an appropriate exercise program.
Many people take calcium supplements.
However, it's important for those considering the use of supplements to check with their doctor first, especially if they have a history of kidney stones. People who take calcium supplements unnecessarily, or who take too much, could end up with a painful case of kidney stones. It is also important for postmenopausal women to consider taking estrogen, since estrogen replacement therapy prevents bone loss. However, there are both risks and benefits to taking estrogen, and only you, in consultation with your doctor, can decide whether this is right for you. It is not a substitute for professional medical advice.
