B Vitamins May Protect Against Damaging Effects of Air Pollution, and Improve Cognition and Psychiatric Health

By Dr. Mercola B vitamins are important for cognition and mental health, but recent research suggests they may have other important functions as well. A small-scale human trial1 found B vitamins may help protect against air pollution.2,3 At high doses, B vitamins were actually able to “completely offset” damage incurred by fine particulate matter. According to a World Health Organization (WHO) report released last year, only 8 percent of people worldwide are breathing air that meets WHO standards.4 This means 92 percent of the world population are breathing polluted air, and toxic environments are responsible for at least 1 of every 4 deaths reported worldwide.5 Poor air quality can cause serious damage to your lungs, heart and other organ systems. One of the most dangerous air pollutants is very fine particulate matter known as PM2.5, particles smaller than 2.5 micrometers — about one-thirtieth the width of a human hair — in diameter.
