Does cigarette smoke exposure affect vitamin D status?

Posted on: April 30, 2014   by  Jeff Nicklas


Results from a new study published in the Journal of Allergy and Clinical Immunology suggest that cigarette smoke is related to lower vitamin D levels and a reduced ability to activate vitamin D in nasal cells.

Cigarette smoke is a known carcinogen and is associated with an increased risk for inflammation in the respiratory system. Previous research has shown that vitamin D may play a role in respiratory health and helps to reduce inflammation.

Despite the role that cigarette smoke and vitamin D play in causing and reducing inflammation, respectively, there hasn’t been much research that has looked at how cigarette smoke might affect vitamin D status and its ability to function in the respiratory system.
