Summary
This study tests whether a daily probiotic supplement can reduce inflammation and other early signs of harm caused by air pollution. Seventy street market vendors in Turin, Italy, will take either the probiotic or a placebo for 4 months. Researchers will measure blood markers of inflammation, DNA damage, and gut health to see if the supplement offers protection.
