ABSTRACT

Previous studies have not been able to show with certainty the effect of vitamin D supplementation in tuberculosis patients. The objective of this study is to determine whether vitamin D supplementation to patients with tuberculosis could influence 25-hydroxy- vitamin D (25(OH)D) and calcium serum levels.
