B vitamins protect heart and blood vessels against air pollution
On one occasion, subjects took placebo every day for 4 weeks prior to exposure. The other time they took a supplement with a solid dose of folic acid, vitamin B12 and vitamin B6.

After exposure to the contaminated air, the concentration of white blood cells [WBC] in the blood also increased. Those white blood cells probably became active because air pollution causes inflammation in the body. Inflammatory processes can damage blood vessels, and probably damage tissues in other ways as well.
Again, supplementation with B vitamins protected against this effect. If the subjects had taken B vitamins in the weeks before exposure, the white blood cell concentration remained stable.
"While regulation is the backbone of prevention, residual risk remains for those who are sensitive, and high exposures are, unfortunately, the rule still in many megacities throughout the world."
"Our project inaugurates a line of research for the development of preventive pharmacological interventions using B vitamins to contain the health effects of air pollution. Future studies will identify the precise pathophysiological processes of PM-induced cardiovascular responses and inflammation, as well as the mechanistic pathway underlying the protective effect of B vitamins."
