Vitamin C kills drug-resistant TB in lab tests

Vitamin C can kill multidrug-resistant TB in the lab, scientists have found.

The surprise discovery may point to a new way of tackling this increasingly hard-to-treat infection, the US study authors from Yeshiva University say in Nature Communications.

An estimated 650,000 people worldwide have multidrug-resistant TB.

Studies are now needed to see if a treatment that works using the same action as vitamin C would be useful as a TB drug in humans.
