Summary

This study will compare adherence, tolerability, safety, and treatment satisfaction between a calcium-rich food and a traditional calcium carbonate supplement in women ages 40 to 90 who are at increased risk for osteoporosis. Participants will be randomly assigned to receive either a calcium-rich food providing 500 mg of calcium from milk-derived minerals or a 500 mg calcium carbonate supplement once daily for four weeks. Participants will complete brief weekly questionnaires assessing supplement use, gastrointestinal symptoms, and treatment satisfaction. The goal of the study is to determine whether the form in which calcium is consumed influences adherence and participant experience. No blood draws, imaging studies, or other invasive procedures are involved
