-What is vitamin D. +**Vitamin D** is synthesized in your skin, upon exposure to the sun. It can also be acquired through the diet, although greater than 90% of the vitamin D supply of our species is understood to be derived from exposure to ultraviolet B light, specifically from the sun.

 The majority of human tissues and cells have a vitamin D receptor. Vitamin D is understood to decrease the risk of chronic illnesses ranging from autoimmune disease to cardiovascular disease to infectious disease. Just a few specific health outcomes include that vitamin D deficiency causes bone and muscle weakness; and increasing vitamin D reduces the risk of fractures, falls, periodontal disease, and colorectal cancer. Vitamin D deficiency is also associated with increased risk of metabolic syndrome. Supplementation with vitamin D in infancy decreases the later development of type I diabetes. Vitamin D deficiency is also a significant risk factor for HIV patients, and likely increases susceptibility of populations to seasonal influenza11. This is consistent with growing evidence that vitamin D functions in regulating the immune system, has many anti-viral properties, and that supplementation with it provides protection against many respiratory infections. The majority of human tissues and cells have a vitamin D receptor.

 The overlap between comorbidities for Covid and conditions associated with vitamin D deficiency raises an obvious question about the relationship: Is vitamin D deficiency causing these other conditions, and these conditions are (independent of vitamin D deficiency) comorbidities for Covid? Or is vitamin D deficiency causal in both Covid (infection and outcomes), and these other conditions? It seems like a very important question to answer. The overlap between comorbidities for Covid and conditions associated with vitamin D deficiency raises an obvious question about the relationship: Is vitamin D deficiency causing these other conditions, and these conditions are (independent of vitamin D deficiency) comorbidities for Covid?

 +==== Vitamin D deficiency in COVID-19 ====
 +
 +Vitamin D deficiency in COVID-19 quadrupled death rate
 +Publish date: December 11, 2020   Author(s): Becky McCall 
 +
 +Vitamin D deficiency on admission to hospital was associated with a 3.7-fold increase in the odds of dying from COVID-19, according to an observational study looking back at data from the first wave of the pandemic.
 +
 +Nearly 60% of patients with COVID-19 were vitamin D deficient upon hospitalization, with men in the advanced stages of COVID-19 pneumonia showing the greatest deficit.
 +
 +Importantly, the results were independent of comorbidities known to be affected by vitamin D deficiency, wrote the authors, led by Dieter De Smet, MD, from AZ Delta General Hospital, Roeselare, Belgium.
 +
 +“[The findings] highlight the need for randomized, controlled trials specifically targeting vitamin D–deficient patients at intake, and make a call for general avoidance of vitamin D deficiency as a safe and inexpensive possible mitigation of the SARS-CoV-2 pandemic,” Dr. De Smet and colleagues wrote in their article, published online Nov. 25 in the [[:American Journal of Clinical Pathology]] ((https://web.archive.org/web/20210419010010/https://www.the-hospitalist.org/hospitalist/article/233376/coronavirus-updates/vitamin-d-deficiency-covid-19-quadrupled-death-rate))
