The study showed that COVID-19 patients had significantly lower vitamin D levels and a significantly higher number of ACE receptors,…
Summary An Israelian study found a direct association between low vitamin D levels and an increased risk of COVID-19 infections. In this study, the data of 7807 participants were used. Participants were tested on COVID-19, and blood samples were used to measure vitamin D levels. Participants who tested positive on COVID-19 had a significantly lower…
Summary This Korean study investigated the effects of several essential micronutrients on the incidence of COVID-19 infections. To this end, several micronutrients were measured in 50 hospitalized patients with COVID-19. This study showed that 76% of these patients were vitamin D deficient, and 42% were selenium deficient. Furthermore, the COVID-19 group showed lower vitamin D…
Summary In a study conducted by several Indian research institutes, the zinc levels of 47 Covid-19 patients were compared with the zinc levels of 45 healthy people (control group). The results showed that a significant number of the involved Covid-19 patients (57,4%) had a zinc deficiency compared to the control group. These patients developed more…
Summary This study, conducted by several Iranian and American research institutes, investigated the association between vitamin D levels and its effect on several adverse clinical outcomes and parameters related to immune function and mortality rate in 235 COVID-19 patients. This study showed a significant association between vitamin D sufficiency, less severe clinical complaints, and better…
Summary This study, conducted by Turkish researchers, investigated the effect of vitamin D levels on COVID-19 severity and mortality in 149 COVID-19 patients. Results showed that patients with critical complaints had significantly lower vitamin D levels than patients with moderate COVID-19 complaints. Vitamin D insufficiency was measured in 93.1% of the patients with critical complaints.…
Summary A study conducted by the University of Chicago examined the association between vitamin D levels and other clinical characteristics related to COVID-19. 489 patients were involved. Patients with a deficient vitamin D level showed a 1.77 times greater risk to test positive for COVID-19. This study showed a direct association between vitamin D deficiency…
Summary A study conducted by several German hospitals investigated the effects of low selenium levels on the mortality risk of COVID-19 patients. Selenium is an essential trace element and important for a well-functioning immune system. In this study, which included 33 participants, the measured selenium levels were significantly higher in surviving COVID-19 patients. According to…
Summary A Chinese study investigated the effects of low calcium levels in critically ill COVID-19 patients. In this study, 107 COVID-19 patients were involved: 67 patients with low calcium levels and 40 patients with normal calcium levels. Several important parameters associated with infectious diseases were measured. It was found that these parameters were worse in…
Summary This study investigated the effects of vitamin D on inflammatory factors in COVID-19 patients. One group of patients received vitamin D daily; the other group only received the standard treatment. The results showed that vitamin D supplementation has a beneficial effect on COVID-19 by reducing inflammatory factors. No side effects were observed. More details…
Summary This study investigated the effect of vitamin D3 supplementation in Covid-19 patients. 66 residents of a nursing home participated in the study. The patients received the vitamin D3 supplementation during or in the month before the Covid-19 infection (intervention group). It was shown that vitamin D3 intake was associated with less severe Covid-19 and…
Summary 986 hospitalized patients with Covid-19 were involved in this study, including 151 patients (16%) who received vitamin D therapy. This study showed that supplementation of vitamin D reduced the risk of mortality in Covid-19 patients. More details can be found in the study.

Summary This study investigated the effect of high-dose zinc infusions on Covid-19 patients. 33 hospitalized adults participated in this study, including 15 patients who received a high-dose zinc infusion and 18 patients who received a placebo. Participants with zinc infusion showed an improved zinc level after the administration period, without adverse side effects. More details…
Summary This study investigated the effect of high-dose intravenous vitamin C supplementation in patients receiving intensive care treatment for Covid-19. 54 critically ill patients were involved in this study, including 26 patients who received the vitamin C infusion and 28 patients who received a placebo infusion. According to this study, vitamin C supplementation is an…
Summary In this study, a group of 17 COVID-19 patients received a combination of vitamin D, magnesium, and vitamin B12. 26 COVID-19 patients served as a control group. The patients who received the micronutrients had a lower need for oxygen therapy and intensive care support than patients in the control group. Further details can be…
Summary This study focused on the effects of a combination of specific micronutrients, including vitamin C, on COVID-19 infections. It was shown that this micronutrient combination can decrease the expression of ACE2 receptors used by the COVID-19 virus to enter the cells and block the potential interaction of the virus and the ACE2 receptors. According…
Summary In this study, vitamin D levels and rates of vitamin D deficiency were measured in 62 patients diagnosed with COVID-19 and 80 healthy controls. The results showed that vitamin D levels were much lower in COVID-19 patients than in the healthy control group. The lowest vitamin D levels were found in the most severe…
Summary This study measured the effects of vitamin D supplementation on Intensive Care Unit Admission and death rate among 76 hospitalized COVID-19 patients. The supplementation of a high dose of vitamin D showed that the need for Intensive Care Unit Treatment decreased and reduced the severity of the disease. Further details can be found in…
