Evidence on the effect of ambient air pollution on vitamin D is limited. This study aimed to examine the association of air pollution exposure with serum levels of 25-hydroxyvitamin D (25OHD) using UK Biobank health datasets. A total of 448,337 subjects were included in this analysis. Land Use Regression was applied to assess individual exposures to particulate matter with diameters ≤2.5 µm (PM2.5), ≤10 µm (PM10), nitrogen dioxide (NO2), and nitrogen oxides (NOx). Linear regression models evaluated the associations between air pollutants and serum vitamin D levels after adjustment of a series of confounders. All analyzed air pollutants were negatively associated with serum vitamin 25OHD levels. After adjusting for potential confounders, a 10 μg/m3 increase in concentrations of

  • PM2.5, PM10, NOx, and NO2 was associated with
  • −9.11 (95%CI: −13.25 to −4.97),
  • −2.47 (95%CI: −4.51 to −0.43),
  • −0.56 (95%CI: −0.82 to −0.30), and
  • −1.64 (95%CI: −2.17 to −1.10) nmol/L

decrease in serum vitamin 25OHD levels, respectively. Interaction analyses suggested that the effects of air pollution were more pronounced in females. In conclusion, long-term exposures to ambient PM2.5, PM10, NOx, and NO2 were associated with vitamin D status in a large UK cohort.

VitaminDWiki - Air Pollution reduces Vitamin D contains

Fact: Pollution reduces the amount of time that people are outdoors
Fact: Pollution is often associated with hot temperatures - another reason to not go outdoors
Fact: Less time outdoors results in lower Vitamin D levels
Fact: Pollution attenuates the amount of UVB getting to the skin (but by only a few percent)
Fact:The body's ability to fight Irritation/Inflammation is aided by vitamin D
Fact: All of the types of PM2.5 deaths are also associated with low vitamin D
Conclusion: Vitamin D supplementation helps the body fight the effects of pollution.

  • Inhaled vitamin D might turn out to be especially good form as it goes directly to the lungs.
