Brief Summary
There is some evidence that supplemental Vitamin D may contribute to quicker recovery from TB when given in addition to normal TB therapy. This needs to be proven with a controlled clinical trial. People receiving Vitamin D with anti TB therapy will be compared against people receiving anti TB therapy alone to see if vitamin D contributes to a quicker recovery (as shown by a quicker sputum culture conversion).
