High doses of B vitamins may “completely offset” the damage caused by very fine particulate matter, according to research reported by BBC News.

The scientists involved say the effect is real but stress the limitations of their work. Follow up studies are urgently needed, they say, in heavily polluted cities like Beijing or Mexico.

According to the World Health Organization (WHO), over 90% of the world’s population live in areas where air pollution exceeds safety guidelines. One of the pollutants that is considered the most dangerous is very fine particulate matter, referred to as PM2.5, where particles have a diameter of less than 2.5 micrometers.
