Two pathways often proposed for smoking decreasing vitamin D:
- Smoking decreases Calcium. and Vitamin D is used up in replacing the Calcium
- Smoking injures the body, and vitamin D is used up in repairing the body

Prospective associations between vitamin D status, vitamin D-related gene polymorphisms, and risk of tobacco-related cancers.
Am J Clin Nutr. 2015 Oct 7. pii: ajcn110510. [Epub ahead of print]

Experimental evidence has suggested that vitamin D may be protective against tobacco-related cancers through the inhibition of the formation of tumors induced by tobacco carcinogens. To our knowledge, only one previous epidemiologic study investigated the association between vitamin D status and tobacco-related cancer risk, and no study has focused on vitamin D-related gene polymorphisms.
Our objective was to prospectively study the association between plasma 25-hydroxyvitamin D 25(OH)D concentrations, vitamin D-related gene polymorphisms, and risk of tobacco-related cancers.
A total of 209 tobacco-related cancers were diagnosed within the SU.VI.MAX (Supplémentation en vitamines et minéraux antioxydants) cohort (1994-2007) and were matched with 418 controls as part of a nested case-control study. Tobacco-related cancers (i.e., cancers for which tobacco is one of the risk factors) included several sites in the respiratory, digestive, reproductive, and urinary systems. Total plasma 25(OH)D was assessed with the use of an electrochemoluminescent assay. Polymorphisms were determined with the use of a TaqMan assay. Conditional logistic regression models were computed.
A 25(OH)D concentration ≥30 ng/mL was associated with reduced risk of tobacco-related cancers (OR for ≥30 vs. <30 ng/mL: 0.59; 95% CI 0.35, 0.99; P = 0.046). This association was observed in former and current smokers (OR for ≥30 vs. <30 ng/mL: 0.43; 95% CI: 0.23, 0.84; P = 0.01) but not in never smokers (P = 0.8). The vitamin D receptor (VDR) FokI AA genotype and retinoid X receptor (RXR) rs7861779 TT genotype were associated with increased risk of tobacco-related cancers [OR for homozygous mutant type (MT) vs. wild type (WT): 1.87; 95% CI: 1.08, 3.23; P-trend = 0.02; OR for heterozygous type (HT) plus MT vs. WT: 1.60; 95% CI: 1.07, 2.38; P = 0.02].
In this prospective study, high vitamin D status [25(OH)D concentration ≥30 ng/mL] was associated with decreased risk of tobacco-related cancers, especially in smokers. These results, which are supported by mechanistic plausibility, suggest that vitamin D may contribute to the prevention of tobacco-induced cancers in smokers and deserve additional investigation. The SU.VI.MAX trial was registered at clinicaltrials.gov as NCT00272428.
Vitamin D deficiency in South Europe: effect of smoking and aging

From conclusion: Smoking was associated with an increased risk of hypovitaminosis D (odds ratio, 1.8; 95% confidence interval, 1.00–3.35).
Many Studies mentioning Smoking and Vitamin D
- Pubmed search for (smoking) AND "vitamin d" in title or abstract got 325 articles March 2015
European Journal of Clinical Nutrition December 1999, Volume 53, Number 12, Pages 920-926
Results: Fifty percent were current smokers. Smokers had significantly reduced levels of serum 25OHD (P=0.02), 1,25(OH)2D (P=0.001), and PTH (P<0.001). There was no difference in serum ionized calcium between smokers and non-smokers. We found a negative effect of smoking on serum osteocalcin (P=0.01), while urinary pyridinolines were similar in the two groups. The small differences in lifestyle between the two groups could not explain these findings. Smokers had small but significant reductions in bone mineral density.
Vitamin D deficiency, Smoking, and Lung Function in the Normative Aging Study; 2012
Measurements and Main Results: In the overall cohort, there was no significant effect of vitamin D deficiency on lung function nor on lung function decline.
In both cross-sectional and longitudinal multivariable models there was effect modification by vitamin D status on the association between smoking and lung function.
Cross-sectional analysis revealed lower lung function in current smokers with vitamin D deficiency (FEV1, FVC, and FEV1/FVC, p? 0.0002) and longitudinal analysis showed more rapid rates of decline in FEV1 (p=0.023) per pack-year of smoking in subjects with vitamin D deficiency as compared to subjects who were vitamin D sufficient.
Conclusions: Vitamin D deficiency was associated with lower lung function and more rapid lung function decline in smokers over 20 years in this longitudinal cohort of elderly men. This suggests that vitamin D sufficiency may have a protective effect against the damaging effects of smoking on lung function. Future studies should seek to confirm this finding in the context of smoking and other exposures that affect lung function.

1 page: How Does Vitamin D Assist Smoking Cessation?
Vitamin D is said to play a crucial role in the stop smoking process.
It is connected to dwindling rates of many forms of cancer, including lung cancer.
In his book titled: “Quitting Cold: A Guide to Quit Smoking,” Carling Kalicak states that vitamin D is also good for bringing depression and stress to the barest minimum.
These 2 withdrawal symptoms (stress and depression) manifest in the first few days of smoking cessation.
Kalicak further recommends that smokers start consuming vitamin D supplements one to two weeks before dropping off cigarettes.
Why is it beneficial to take vitamin A when quitting smoking?
It is no secret that smoking is disastrous for the lungs.
Studies have suggested that vitamin A helps bolster the minuscule hair-like objects in the lungs known as "cilia."
Cilia play an important role in cleaning and protecting the lungs.
How does vitamin C help for quitting smoking?
Like vitamin A, it is important to take vitamin C when recovering from a smoking addiction because it helps counteract some of the damage that tobacco use does to the body.
However, vitamin C also helps with nicotine cravings. While smoking has been shown to reduce the amount of vitamin C in the body, large doses of the vitamin potentially reduce cravings.
Why is vitamin D beneficial when quitting smoking?
Vitamin D has a wide range of health benefits, including being associated with lower rates of cancer.
This beneficial vitamin has also been proven to have mental health benefits, such as stress reduction.
Anybody who has attempted to quit smoking is able to tell you the importance of reducing stress during the process.
DID YOU KNOW?
Magnesium supplements are sometimes recommended for those trying to quit smoking.
Taking magnesium helps ease anxiety and reduce intense nicotine cravings.

Cigarette smoke extracts (CSE) alter calpain-1 expression via ERK signaling pathway in bronchial epithelial cells. 1α,25-dihydroxyvitamin D3 (1,25D3) inhibits cigarette smoke-induced epithelial barrier disruption.
This study was aimed to explore whether the 1,25D3 counteracted the CSE effects in a human bronchial epithelial cell line (16HBE). In particular, transepithelial electrical resistance (TER) and permeability, expression and distribution of E-cadherin and β-catenin, calpain-1 expression, and ERK phosphorylation were assessed in the CSE-stimulated 16HBE cells. The CSE induced the ERK phosphorylation, improved the calpain-1 expression, increased the distribution anomalies and the cleaving of E-cadherin and β-catenin, and resulted in the TER reduction and the permeability increase. The 1,25D3 reduced these pathological changes. The 1,25D3 mediated effects were associated with a reduced ERK phosphorylation.
In conclusion, the present study provides compelling evidences that the 1,25D3 may be considered a possible valid therapeutic option in controlling the cigarette smoke-induced epithelial barrier disruption.

Chronic obstructive pulmonary disease (COPD) is a chronic disease characterized by a progressive expiratory airflow limitation and is associated with chronic inflammation in the airways and lung parenchyma . In the majority of cases, this inflammatory response in COPD is initiated by long-term exposure to cigarette smoke (CS), which triggers a series of events that damage the airways and terminal airspaces, leading to lung function decline and emphysema.
