Keeping bones healthy in older age is crucial to protecting mobility and independence. One way to do that is with weight-bearing activity each week. That includes strength training or any activity that gets a person up and moving. Another way is meeting calcium requirements: 1,000 to 1,200 milligrams (mg) per day for men ages 51 and older, and 1,200 to 1,500 mg per day for women 51 and older. Vitamin D is helpful for calcium absorption, typically 800 to 1,000 IU daily for adults. Reducing risk factors for osteoporosis, such as smoking and excessive alcohol consumption, is also important.
