Your skeleton contains 99 percent of your body's calcium. Clinical studies show that taking calcium and vitamin D supplements reduces the risk of hip and spine fractures. Men 65 and older should consume at least 1,500 mg of calcium daily. Chewable antacids that contain calcium carbonate are good supplemental sources of calcium. Do not take antacids containing aluminum or magnesium.
Bones respond to the force of muscles at work.
Exercise may help your bones build calcium reserves and improve your agility, strength and balance all of which reduce your chances of falling and breaking a bone. Exercise can offer protection from additional bone loss for men with osteoporosis. Do weight-bearing exercises at least three times each week. Walk or run. Lift weights, but use appropriate caution.
