Vitamin D: Role in Defence Against Respiratory Infections
Basis for role in COVID 19: Vitamin D: Role in defence against respiratory infections
Low Plasma 25(OH) Vitamin D Level is Associated with Increased Risk of Covid‐19 Infection
The current study, published in the journal FEBS, the research team examined data of 7807 people who recently underwent a COVID-19 test as well as a Vitamin D blood test. The findings showed that low levels of Vitamin D in the blood was identified as independently associated with the likelihood of COVID-19 infection. According to …
Vitamin D Supplementation Could Reduce Risk of Influenza & COVID 19 Infections and Deaths
Vitamin D stimulates Cathelicidins and Defensins to lower viral replication rates Reduces concentrations of pro-inflammatory cytokines that produce inflammation and injures to the lining of the lungs Vitamin D increases concentrations of anti-inflammatory cytokines A study conducted in Connecticut revealed that Vitamin D concentrations of 38ng/ml or more were associated with 2 times reduction in …
Vitamin D a Key Modulator of Innate Immunity and Natural Defense From Acute Viral Respiratory Infections
Calcitriol has been found to induce the transcription of antimicrobial peptides – such as cathelicidin and defensin. Functional VDR has been identified in almost all immune cells, including neutrophils and antigen-presenting cells. In vitro studies have shown that vitamin D decreases the expression of pro-inflammatory cytokines and increases the production of antiviral proteins, suggesting an …
Vitamin D Insufficiency and Deficiency and Mortality from Respiratory Diseases in a Cohort of Older Adults
A new cohort study involving 9940 men and women has added to the mounting research to indicate Vitamin D supplementation may reduce the seriousness of COVID-19 infections. It has been suggested that Vitamin D3 supplementation could be a potentially promising and safe approach to reduce risk of COVID-19 infections and deaths. Meta-analyses of randomized clinical …
SARS-COV-2 Positivity Rates Associated with Circulating 25-Hydroxy Vitamin D Levels
A recent study conducted by Quest Diagnostics and Boston university stating the associations between Vitamin D levels and COVID 19 risk continues to strength indicating that people with low levels of Vitamin D may have a significantly higher possibility of showing high positive rate of SARS -CoV-2. The SARS-CoV-2 positivity rate was higher in the …

Vitamin D Linked to Low Virus Death Rate
A new study has found an association between low average levels of vitamin D and high numbers of COVID-19 cases and mortality rates across 20 European countries. Previous observational studies have reported an association between low levels of vitamin D and susceptibility to acute respiratory tract infections. Vitamin D modulates the response of white blood …
Vitamin D and the Incidence of Acute Viral Respiratory Tract Infections in Healthy Adults
Our body converts vitamin D to a chemical known as 25-hydroxyvitamin D, also called Calcidiol. Declining serum concentrations of 25-hydroxyvitamin D seen in fall and winter as distance increases from the equator may be a factor in the seasonal increased prevalence of influenza and other viral infections. This study was done to determine if serum …
Vitamin D for Prevention of Respiratory Tract Infections: A Systematic Review and Meta-Analysis
Acute respiratory infection (ARI) is widespread not only in the paediatric age group but also in adults. Respiratory tract infections are the major cause of mortality and morbidity. There are limited options available for treatment and prevention of ARI. Antibiotics are the mainstay of treatment for pneumonia. In the developing countries, zinc and vitamin supplementation …
