Researchers in Belgium have discovered a "clear link" between low levels of vitamin D and the severity of COVID-19 cases. Studies consistently show that at least 40 percent of the Belgian population has inadequate levels of vitamin D, known as the "sunshine vitamin." But scie...
治疗变化的定义为从最近一次测定维生素D水平的日期到COVID-19检测日期之间的维生素D类型和剂量的变化。结合维生素D缺乏和治疗改变,将COVID-19检测前的最近维生素D状况分为:可能不足(最近维生素D水平不足且治疗未增加)、可能充足(最近维生素D水平没有不足且治疗未减少)和两组不确定不足(最近维生素D水平不足和治疗增...

Backman said much more research is needed to know how vitamin D could be used most effectively to protect against COVID-19 complications. "It is hard to say which dose is most beneficial for COVID-19," Backman said. "However, it is clear that vitamin D deficiency is harmful, and it ca...
Mechanistic and observational evidence suggests that COVID-19 is less severe in people with adequate vitamin D levels. Vitamin D supplementation seems to help prevent COVID-19 complications, but only two randomized trials have been conducted thus far...
Vitamin D supplementationCOVID-19, the acute respiratory tract infection (RTI) caused by the Coronavirus, Sars-CoV-2, has swept around the world. No country has been spared from its onslaught. Treatments that can reduce the risk of infection and mortality from the disease are desperately needed...
Vitamin D is an essential nutrient, and recent research has suggested it may also help guard against severe COVID-19.
While vitamin D levels of 30 nanograms per milliliter (ng/ml) or more are typically considered sufficient, Black people who had levels of 30 to 40 ng/ml had nearly triple the odds of testing positive for COVID-19 compared to people with levels of 40 ng/ml or more. The level of vita...
The COVID-19 pandemic has spurred renewed interest in vitamin D to address viral replication and hyperinflammation that have a major role in the pathogenesis of severe COVID-19. In addition to known antimicrobial and anti-inflammatory effects, vitamin D metabolites also have direct action on angiot...
A trial in Spain treated patients with COVID-19 with active vitamin D and looked at whether the vitamin reduced deaths or intensive care (ICU) admissions. Their results suggested an 80% reduction in admissions to ICU and a 60% reduction in deaths. But after they published their results, the...
