Highlights:

•Lower serum 25-hydroxyvitamin D increases susceptibility to tuberculosis.
•BsmI and FokI VDR gene polymorphisms may confer increased risk of acquiring tuberculosis.
•Vitamin D supplementation reduces tuberculosis incidence and increases recovery from tuberculosis.

Objective
To investigate the impacts of vitamin D status, supplementation and vitamin D receptor (VDR) gene polymorphisms on tuberculosis (TB).

Methods
We conducted a systematic review of published studies pertaining to case-control and randomized-control trials from 2002 to 2014 using the PubMed database.

Results and conclusion:
Individuals with TB have lower vitamin D status than healthy individuals. Some VDR gene polymorphisms are associated with increased susceptibility to TB while others may not. Supplementation with vitamin D leads to improved clinical outcomes. However, further studies with a larger patient population and different ethnicities are needed to confirm these effects.

ALL random controlled trial showed reduction of TB when Vitamin D was added
unless there was a very long time between doses (5 months) or very small doses of vitamin D were used (800 IU/day)
