Smoking reduces vitamin D


Two pathways are often proposed for how smoking decreases vitamin D:
   1) Smoking decreases Calcium. and Vitamin D is used up in replacing the Calcium
   2) Smoking injures the body, and vitamin D is used up in repairing the body
It appears that taking Vitamin D while smoking will:
   1) Decrease the incidence of the many health problems associated with smoking - even lung cancer
   2) Decrease the desire to smoke (perhaps take fewer smoking breaks?)
   3) Increase breathing capacity
Opinion: If unable to stop smoking,
  or are a previous smoker,
     or are getting 2nd hand smoke,
         increase Vitamin D and perhaps Omega-3 (which decreases depression, inflammation)

Vitamin D should also help people quit smoking   See bottom of page Smoking reduces vitamin D
   1) Reduces weight gain associated with quitting smoking
   2) Reduces depression associated with quitting smoking

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.
Hard to quit smoking if low vitamin D - 2016
Evaluation of the relationship between serum vitamin D levels and tobacco use disorder
Tijen Şengezer, Rabia Nazik Yüksel, Tuğba Babacan, Hüseyin Can, Nesrin Dilbaz.

Objective: In recent years; vitamin D, being a steroid hormone with neuroprotective and anti-oxidant effects apart from the effects on musculoskeletal system and endocrine system has been emphasized and studies on the relation of metabolic diseases, malignancies, neuropsychiatric diseases with vitamin D has been performed. A pandemic deficiency of vitamin D is mentioned all around the world. Although it has been reported that there is a relation between tobacco consumption and vitamin D; literature is limited and no data from Turkey regarding to the tobacco consumption and vitamin D has been reported.
To evaluate vitamin D levels in individuals admitted to our hospital’s ‘smoking cessation unit’ and accordingly, to investigate the relation of vitamin D levels with tobacco dependence. Methods: Seventy-two cases between ages of 17-69 referring to smoking cessation unit were included in our study. Retrospectively, demographic data form the patients’ files, Fagerström Test for Nicotine Dependence (FTND), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) forms were examined and levels of vitamin D were recorded. Whether the parameters conform the normal distribution or not is evaluated by Kolmogorov-Smirnov test. In statistical analyses; Mann-Whitney U test, Kruskall-Wallis H test, one way ANOVA were applied. p<0.05 level was accepted as statistically significant.

Results: Mean age of the cases was 46.5±12.3 (17-69) years, 36 of them (50%) were female. The average years of smoking was 25.6±12.0 (1-50) years, average daily cigarette use at admission was 21.1±9.7 (2-60), average score of FTND was 6.2±2.4 (1-10). A statistical significance was determined among sex groups by means of vitamin D levels. A low but statistically significant and inverse relation has been observed between vitamin D levels and BDI score. Considering the year of smoking, height, weight, age, score of FTND and BAIQ; no statistical significance has been determined between these variables and vitamin D levels.

Conclusion: Tobacco use has a relation with low levels of 25(OH)D. Although the mechanisms regarding to tobacco consumption and vitamin D deficiency are not enlightened yet; the evaluation of vitamin D levels in the routine examination of tobacco consumers, replacement of vitamin D if there is any deficiency and their exposure to daylight will be beneficial considering the neuroprotective and anti-oxidant effects of vitamin D.

Black women smokers have the lowest vitamin D levels – Feb 2020

History of Tobacco, Vitamin D and Women
Int J Vitam Nutr Res, 1-6 2020 Feb 24, DOI: 10.1024/0300-9831/a000640
Kiano Reza Manavi 1, Brenda Pauline Alston-Mills 2, Marvin Paul Thompson 3

Tobacco usage kills more than 8 million people a year. Approximately 7 million of those deaths are the result of direct tobacco use, while approximately 1.2 million are the result of non-smokers being exposed to second-hand smoke. About 200 million of the world's one billion smokers are women and usage among women is increasing in some countries. Nicotine from smoking tobacco, specifically its metabolite cotinine, has negative effects on human health causing lung cancer, COPD and non-respiratory problems. Over a billion people worldwide are Vitamin D deficient or insufficient, which is prevalent across all age-groups, geographic regions, and sunlight. With the discovery of Vitamin D in 1919, a new chapter in the prevention of rickets was introduced opening the door to its therapeutic properties for other diseases. Since 1919, there have been many clinical and epidemiolocal studies performed globally on the effect of the vitamin on prevention of other diseases, including but not limited to, cancer, autoimmune disorders, cardiovascular diseases, and osteoporosis. Exposure to environmental tobacco smoke has been associated with reduced levels of Vitamin D in the blood stream and sinus tissues. Manavi et al. (2015) demonstrated that among three smoking categories (heavy, light, non-smokers),

  • black female heavy smokers have lower vitamin D (13.374 ng/ml), than
  • Hispanic (19.213 ng/ml) or
  • white (24.929 ng/ml)

females correlating to higher levels of cotinine. Therefore, blood serum concentrations of cotinine contribute to decreased Vitamin D concentrations in addition to other factors such as gender and ethnicity.


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]
Deschasaux M1, Souberbielle JC2, Latino-Martel P3, Sutton A4, Charnaux N4, Druesne-Pecollo N3, Galan P3, Hercberg S5, Le Clerc S6, Kesse-Guyot E3, Ezzedine K7, Touvier M3.

BACKGROUND:
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.

OBJECTIVE:
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.

DESIGN:
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.

RESULTS:
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].

CONCLUSIONS:
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.

Many medical studies mentioning Smoking and Vitamin D


The influence of smoking on vitamin D status and calcium metabolism

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.

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.

From Background
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.

Many people gain weight after quiting smoking - Vitamin D can help

Image

Note: My mother smoked most of her life and died of lung cancer.
She had tried several times to quit the addiction.
Every time she tried quitting she gained too much weight, so went back to smoking.
Henry Lahore, founder of VitaminDWiki

Note: Your Vitamin D levels must be > 30 ng to be of any benefit.
You cannot just stop smoking and start taking 4,000 IU of vitamin D and expect any help in stopping smoking.
Must either start taking 4,000-5,000 IU two months BEFORE stopping smoking OR start with a loading dose when stopping

"It took more than 7,000 studies ... before the first Surgeon General report against smoking was finally released in the 1960s"
Then it took the AMA another 10 years to agree with the Surgeon General

Note: The founder of VitaminDWiki has been exploring multiple ways to add Vitamin D to cigarette filters such that the warm air would vaporize the vitamin D. Thus ZERO extra effort would be needed by the smoker to increase thier vitamin D levels

Faster decline in lung function when smokers had low vitamin D – April 2021

Vitamin D deficiency and lung function decline in healthy individuals: A large longitudinal observation study
Respir Med. 2021 Apr 20;182:106395. doi: 10.1016/j.rmed.2021.106395
Kyung-Min Ahn 1, Sun-Sin Kim 2, Suh-Young Lee 1, So-Hee Lee 2, Heung-Woo Park 3

Aim: A reliable evidence from a comprehensive large-scale study supporting associations between serum vitamin D (25-hydroxyvitamin D) level (SVDL) and lung function decline (LFD) in healthy individuals has been unavailable. Using a well-established health screening database, we assessed the associations between SVDL and LFDs, measured as the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and FEV1/FVC ratio.

Methods: Serial SVDL and lung function data were analyzed using linear mixed models, which were performed in smokers and non-smokers, separately. Vitamin D-deficient individuals (VDDs) were defined when their SVDLs were consistently lower than 20 ng/mL at all measurements.

Results: A total of 1371 individuals were analyzed. The mean FEV1 decline rates of VDDs and vitamin D-normal individuals (VDNs) in smokers were -33.35 mL/year (95% CI: 39.44 to -27.26 mL/year) and -15.61 mL/year (95% CI: 27.29 to -4.21 mL/year) respectively, over a mean of 6.29 years of observation with statistical significance (P < 0.001). However, there was no significant differences observed between decline rates of FEV1 in non-smokers. Similarly, FVC decline rates of VDDs were significantly greater than those of VDNs only in smokers (P < 0.001). However, FEV1/FVC ratio decline rates showed no significant difference between VDDs and VDNs regardless of their smoking status.

Conclusions: Consistently low SVDLs predicted more rapid FEV1 and FVC declines in smokers. However, FEV1/FVC decline rate was not associated with SVDL. SVDL may be used to identify healthy smoking individuals at high risk for accelerated LFD.
