Objectives: To evaluate the effects of calcium supplementation in postmenopausal women and changes in serum calcium and phosphorus levels. Study Design: Randomized controlled trial. Place and Duration: In the Obstetric and Gynecology department of Nishtar Hospital, Multan for one-year duration from May 2019 to May 2020. Patients and method: 98 postmenopausal women for 12 months. The patients were randomly divided into two groups. Patients in the calcium supplemented group (CSG) were to take a calcium supplement (1,200 mg / day), while the control group was not given any placebo and were advised to continue their regular diet. Results: The study found that calcium supplementation increased the subject's daily calcium intake, which kept serum calcium levels within the normal range. Serum magnesium and phosphorus levels in this study remained normal, although there is a slight decrease in serum phosphorus levels which may be due to a reduction in the daily intake of this mineral. Conclusion: Calcium supplementation significantly slowed the bone loss process in postmenopausal women and helps maintain serum calcium levels. Key words: calcium supplements, serum calcium, magnesium, postmenopausal phosphorus.
