After being informed regarding the study protocol and requirements, participants given informed consent were interviewed using a questionnaire for collection of background data and medical history as a screening process. Eligible participants were randomly assigned in a double-blind manner to receive daily 500 mg of calcium with either 0, 600 IU, 1200 IU or 4000 IU vitamin D supplement for 16 weeks. Questionnaires and anthropometric measurements were collected at baseline and post 16 weeks supplementation trial.
