Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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. Primary outcomes of plasma 25(OH)D and intact PTH were measured via fasting intravenous blood samples at baseline and post 16 weeks trial.
