What is the recommended daily calcium intake for women aged 51 and older who are not on estrogen replacement therapy (ERT)?

• A. 1000 mg/day
• B. 1200 mg/day
• C. 1500 mg/day
• D. 2000 mg/day

Answer: (C)

For women aged 51 and older who are not on estrogen replacement therapy, the recommended daily calcium intake is 1200 mg. This recommendation is primarily due to the increased risk of osteoporosis and bone density loss that occurs post-menopause, when estrogen levels decline. Adequate calcium intake is crucial because it helps to maintain bone density and overall bone health during this vulnerable period.

The specific need for 1200 mg/day reflects guidelines made by health organizations, which recognize that as women age, their bodies require more calcium to help mitigate the loss of bone mass. This amount is intended to support bone strength and reduce the risk of fractures, particularly in populations at higher risk for osteoporosis.

Other options such as 1000 mg/day, 1500 mg/day, or 2000 mg/day exceed or fall short of the established guidelines for this age group and particular condition regarding estrogen replacement. Thus, 1200 mg/day is the most appropriate recommendation to support optimal bone health in this demographic.
