Investigation of Zinc Supplement Impact on the Serum Biochemical Parameters in Pulmonary Tuberculosis: A Double Blinded Placebo Control Trial.

Background: Zinc (Zn) is nutritionally essential trace element, and thus deficiency may severely affect human health. The results of cross-sectional studies indicate that micronutrient deficiencies are common in patients with tuberculosis. Our goal is to investigate whether Zn supplementation can increase the effects of anti-TB treatment or not.
