Vitamin D dose can fight off TB for weeks

A SINGLE dose of vitamin D may be enough to ward off developing tuberculosis (TB) for six weeks or more, researchers claimed yesterday.

A study published in the American Journal of Respiratory and Critical Care Medicine found that a single 2.5mg dose of vitamin D may be enough to boost the immune system to fight TB and similar bacteria for at least six weeks.

Researchers from Queen Mary’s School of Medicine and Dentistry and the Wellcome Trust Centre for Research in Clinical Tropical Medicine at Imperial College London studied about 200 patients who had been exposed to TB.
