NEW YORK (Reuters Health) - In healthy people who have been exposed to tuberculosis, a single oral dose of vitamin D enhances their immunity against this bacterial infection."Vitamin D was used to treat tuberculosis in the pre-antibiotic era,” Dr. Adrian R. Martineau, of Queen Mary’s School of Medicine and Dentistry, London, and colleagues note. Studies that have evaluated the effects of vitamin D supplements on tuberculosis immunity have not been performed, they point out in their report, published in the American Journal of Respiratory and Critical Care Medicine.
