Overview Tuberculosis and Vitamin D has the following summary
Many studies have found that Vitamin D both PREVENTS and TREATS TB
- As with many other diseases, we expect that there will be at least a 4X range of vitamin D due to:
- 4X range in the response in the vitamin D blood level for the same IU dose - for healthy, non-obese, people
- Poor Vitamin D Receptor activation results in far less vitamin D getting to cells
- However, a VDR restriction is not noticed by Vitamin D blood tests
- UV appears to be as powerful or perhaps more powerful than vitamin D in TREATING TB
- Tuberculosis -100 percent cure rate with 10,000 IU of vitamin D daily – RCT 2006
- TB 10X less likely to catch if have sufficient vitamin D – Dec 2011
- Trials using small vitamin D doses neither prevent nor treat TB 2023 2022 2020
- No tuberculosis if more than 80 ng of vitamin D (cattle) - Jan 2022
- Humans need a lot of Vitamin D as well
- - - - - - - -
- Tuberculosis recovery speeded up by single 450,000 IU dose of vitamin D – RCT Jan 2017
- Tuberculosis -100 percent cure rate with 10,000 IU of vitamin D daily – RCT 2006
- Every TB patient benefited from 2 doses of 600,000 IU of vitamin D – RCT Jan 2013
- TB arrested by cod-liver oil (containing vitamin D) in 1848 3X better than other treatments at the time
Items in both categories TB and Meta-analysis are listed here:
- Latent Tuberculosis 44 percent less likely if Vitamin D more than 30 ng - 14th meta-analysis Jan 2022
- Those with TB were 3.2 X more likely to have low vitamin D – 13th meta-analysis Sept 2021
- Tuberculosis still associated with low vitamin D – 12th meta-analysis June 2021
- Tuberculosis 3X more likely if less than 12 ng of Vitamin D - meta-analysis Sept 2019
- Tuberculosis increased risk if poor Vitamin D receptor varies by race – meta-analysis Feb 2019
- Tuberculosis (multi-drug resistant) was 13.4 X more likely to be quickly cleared with Vitamin D - Meta-analysis Feb 2019
- Catching Tuberculosis from family member 2 X more likely if low vitamin D – meta-analysis Dec 2018
- Tuberculosis in children 1.7 X more likely if low vitamin D – meta-analysis Aug 2018
- Low vitamin D is a risk factor for tuberculosis – meta-analysis Dec 2016
- Tuberculosis 1.3 times more likely if poor Vitamin D Receptor – meta-analysis Oct 2016
- Tuberculosis 4.5X more likely if vitamin D less than 10 nanogram – meta-analysis May 2015
- Tuberculosis, genes and vitamin D – Meta-Analysis Dec 2013
- TB associated with low vitamin D in a review and meta-analysis – 2008
- TB and vitamin D updated review and meta-analysis – plays a role Jan 2010
A Poor Vitamin D Receptor prevents Vitamin D in blood from getting to the cells
The risk of 44 diseases at least double with poor Vitamin D Receptor as of Oct 2019
Vitamin D Receptor activation can be increased by any of: Resveratrol, Omega-3, Magnesium, Zinc, Quercetin, non-daily Vit D, Curcumin, intense exercise, Ginger, Essential oils, etc Note: The founder of VitaminDWiki uses 10 of the 12 known VDR activators
Items in both categories TB and Vitamin D Receptor:
- TB patients had low Vitamin D and poor Vitamin D receptor – June 2019
- TB and Leprosy are easily confused and associated with Vitamin D Receptor
- Certain types of Tuberculosis are 2X more likely with a poor Vitamin D Receptor – April 2019
- Tuberculosis increased risk if poor Vitamin D receptor varies by race – meta-analysis Feb 2019
- Pulmonary Tuberculosis 2X more likely if poor Vitamin D Receptor (Mexico) – April 2018
- TB risk in Blacks increased 20 percent having poor Vitamin D Receptors – Sept 2017
- Tuberculosis 1.3 times more likely if poor Vitamin D Receptor – meta-analysis Oct 2016
- Tuberculosis, genes and vitamin D – Meta-Analysis Dec 2013

Standard mean differences of Vitamin D and TB
Background: Tuberculosis remains a global threat and a public health problem that has eluded attempts to eradicate it. Low vitamin D levels have been identified as a risk factor for tuberculosis infection and disease. The human cathelicidin LL-37 has both antimicrobial and immunomodulatory properties and is dependent on vitamin D status. This systematic review attempts to compare vitamin D and LL-37 levels among adult pulmonary tuberculosis patients to non-pulmonary TB individuals between 16-75 years globally and to determine the association between vitamin D and cathelicidin and any contributing factor among the two study groups.
Methods/design: We performed a search, through PubMed, HINARI, Google Scholar, EBSCOhost, and databases. A narrative synthesis through evaluation of vitamin D and LL-37 levels, the association of vitamin D and LL-37, and other variables in individual primary studies were performed. A random-effect model was performed and weighted means were pooled at a 95% confidence interval. This protocol is registered under the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42019127232.
Results: Of the 2507 articles selected 12 studies were eligible for the systematic review and of these only nine were included in the meta-analysis for vitamin D levels and six for LL-37 levels. Eight studies were performed in Asia, three in Europe, and only one study in Africa. The mean age of the participants was 37.3±9.9 yrs. We found low vitamin D and high cathelicidin levels among the tuberculosis patients compared to non-tuberculosis individuals to non-tuberculosis. A significant difference was observed in both vitamin D and LL-37 levels among tuberculosis patients and non-tuberculosis individuals (p = < 0.001).
Conclusion: This study demonstrated that active pulmonary tuberculosis disease is associated with hypovitaminosis D and elevated circulatory cathelicidin levels with low local LL-37 expression. This confirms that vitamin D status has a protective role against tuberculosis disease.
