Answer

The Institute of Medicine (IOM) has issued recommendations for calcium and vitamin D daily intake in older adults. For women older than 50 years, the IOM recommended 1200 mg/day of calcium. The IOM recommended 1000 mg/day of calcium for men 51-70 years of age and 1200 mg/day for men over 70. For both sexes, the recommended upper level was 2000 mg/day. [190]

For both women and men, the recommended daily dietary allowance of vitamin D was 600 IU from age 51-70 and 800 IU for after age 70, with a recommended maximum of 4000 IU. Amid considerable controversy, the IOM also stated that the evidence supported a role for vitamin D and calcium in bone health, but not in other conditions. [190]

The minimum daily requirement of vitamin D in patients with osteoporosis is 800 IU of cholecalciferol. Many patients require higher levels (continuously or for a short period) to be considered vitamin D replete, which is defined as a serum 25-hydroxyvitamin D level of at least 32 ng/mL.
