Researchers launch new clinical trial to investigate role of vitamin D against COVID-19

Researchers from Queen Mary University of London, funded by Barts Charity, have launched a new clinical trial to investigate whether taking vitamin D could protect people from COVID-19

Researchers call for nutritional guidelines and regulations on use of vitamin D

The professional perception of vitamin D as a medicine, rather than as a key nutrient, is constraining practice and jeopardizing the health of elderly care home residents in England, conclude researchers in the journal BMJ Nutrition Prevention & Health.

Study shows LED-based UV irradiation prevents bone and muscle loss in aging mice

A research team at Nagoya University in Japan has revealed that narrow-range ultraviolet (UV) irradiation using light emitting diodes (LEDs) safely increases serum vitamin D levels in aging mice and thereby prevents the loss of their bone and muscle mass.

WHO’s report may lead to greater awareness and deliver better eye health for all

Of the world's 7.8 billion people, 2.2 billion have impaired vision. Of this number, about half are treatable. In effect, they are one-eyed kings who are better off than the 39 million who are completely blind. Nevertheless, they are handicapped for normal living, as we gleaned from the first world report on vision by WHO.

Vitamin D deficiency may predict COVID-19 seroconversion

A recent study published on the preprint server medRxiv* in October 2020 reports the potential contribution of vitamin D deficiency to an increased risk of COVID-19 in a subset of health care workers in the UK.

Higher vitamin D levels in pregnancy may protect children from developing high blood pressure

Children appear to be at greater risk of having high blood pressure when their mothers had the high blood pressure condition called preeclampsia during pregnancy--but this adverse association may be reduced or even eliminated for children who were exposed to higher levels of vitamin D in the womb, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.

Vitamin D deficiency during early development can influence metabolic health

Using a zebrafish model, researchers from North Carolina State University have found that vitamin D deficiency during early development can disrupt the metabolic balance between growth and fat accumulation.

Healthy vitamin D levels could reduce COVID-19 complications

Published in the journal PLOS ONE, the study investigates the link between serum 25-hydroxyvitamin D levels and its effect on adverse clinical outcomes and parameters of immune function and mortality due to COVID-19.

Vitamin E is essential for proper growth of nervous system

In research with key ramifications for women of childbearing age, findings by Oregon State University scientists show that embryos produced by vitamin E-deficient zebrafish have malformed brains and nervous systems.

Genomic adaptations to rice‐based diets contribute to mitigation of metabolic risk

The traditional rice-based diet of some east-Asian population has brought to a number of genomic adaptations that may contribute to mitigating the spread of diabetes and obesity.

$Novel tool uses fat to diagnose musculoskeletal disease and predict falls, fractures$

Novel tool uses fat to diagnose musculoskeletal disease and predict falls, fractures

Doctors will soon be able to use fat to diagnose musculoskeletal disease within seconds and predict the risk of falls and fractures in older people, thanks to a world-leading tool developed by Melbourne researchers.

Alcohol-induced vitamin B1 deficiency can be a key factor in cognitive decline

A common consequence of chronically high alcohol consumption is a decline in cognitive function, which can even progress to full-blown dementia. However, we do not yet fully understand how alcohol damages the brain.

Vitamin D deficiency can increase risk of COVID-19

Researchers from Israel have found that there could be a link between deficiency of vitamin D and infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their study titled, “The link between vitamin D deficiency and COVID-19 in a large population,” has been released pre-publication at the medRxiv* server.

Vitamin D levels in the blood may be a better predictor of future health and disease risks

Free, circulating vitamin D levels in the blood may be a better predictor of future health risks in aging men, according to a study being presented at e-ECE 2020.

Study finds link between vitamin D deficiency and risk of COVID-19 infection

In a retrospective study of patients tested for COVID-19, researchers at the University of Chicago Medicine found an association between vitamin D deficiency and the likelihood of becoming infected with the coronavirus.

Vitamin D supplements do not prevent severe asthma attacks in children

Contrary to earlier results, vitamin D supplements do not prevent severe asthma attacks in at-risk children, according to the first placebo-controlled clinical trial to test this relationship.

Researchers identify shared molecular roots between lipid dysfunction and autism

Researchers at Harvard Medical School, Massachusetts Institute of Technology and Northwestern University have identified a subtype of autism arising from a cluster of genes that regulate cholesterol metabolism and brain development.

Vitamin D does not reduce risk of depression or mood changes

Several studies have shown that those with Vitamin D deficiency also have symptoms of depressive illness. The authors wrote, "Low levels of 25-hydroxyvitamin D have been associated with a higher risk for depression later in life, but there have been few long-term, high-dose large-scale trials."

Can Vitamin D help combat the coronavirus?

In a new report published in The Lancet, a team of researchers discussed the possibility that vitamin D could offer protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The meta-analyses of randomized controlled trials performed from 2007 to 2020.
