Can vitamin D3 protect from COVID?
Vitamin D is a fat-soluble vitamin that plays an important role in your body. It is also important for the health of the immune system. Many people are wondering if vitamin D supplementation can help reduce coronavirus risk. At COVID-19, precautions such as adequate hygiene and physical spacing can protect them from the virus. In addition, some investigations suggest that a healthy vitamin D levels can help to keep the immune system healthy and prevent frequent respiratory diseases. A recent study revealed that patients with CovID-19 in the hospital who had a sufficient vitamin D levels had a lower risk of death.
Vitamin D and immune system
Vitamin D is essential for the proper function of the immune system. A healthy immune system acts as a defense system against infections and diseases. This vitamin plays an important role in strengthening the immune response. It has anti-inflammatory and immune regulating properties and is important for activating the immune defense. Vitamin D helps to improve the function of immune cells, including macrophages and T cells that protect their body from pathogens. Vitamin D is for the function of the Immune system so important that a low vitamin D levels is associated with increased susceptibility to diseases, infections and immunism.
Thus, a low vitamin D mirror is associated with an increased risk of respiratory diseases, including asthma, tuberculosis, chronic obstructive pulmonary disease as well as bacterial and viral respiratory tract infections. In addition, a vitamin D deficiency is associated with decreasing lung function, which can affect the ability of the body to combat airway infections.
Vitamin D and Covid
In some studies, the impact of a vitamin D deficiency was examined for the risk of infection with the new Coronavirus SARS-COV-2. However, a recent study revealed that a blood level of 25-hydroxyvitamin D of at least 30 ng / ml reduced the risk of adverse clinical results and death in hospitalized patients with COVID-19. 235 patients with Covid-19 in the hospital were analyzed. Patients over 40 years with healthy vitamin D values had a 51.5% lower risk for adverse consequences such as hypoxia, unconsciousness and death as patients with vitamin D deficiency. Other studies show that a vitamin D deficiency can affect immune function and increase the risk of respiratory diseases. In addition, some studies point out that vitamin D preparations can strengthen the immune response and prevent respiratory infections.
In a recent study with 11 321 people from 14 countries, it has been found that vitamin D supplementation reduced the risk of acute respiratory infections for persons with vitamin D deficiency and sufficient vitamin D levels. According to the study, a vitamin D supplement decreased the risk of 12% acute respiratory infections. The protective effect was most strongest in people with low vitamin D levels. In addition, studies have shown that vitamin D supplements are most effective against acute respiratory infections when taken daily or weekly in small doses, and less if they are taken in large, widely distributed doses. A study shows that vitamin D preparations help to reduce mortality in older adults that are most at risk of suffering from respiratory diseases such as Covid-19. In addition, it is known that vitamin D deficiency triggers a process called the cytokin tower.
Cytokines are proteins that are an important part of the immune system. They can have both anti-inflammatory and anti-inflammatory effects and play an important role in the prevention of infections and diseases. In some cases, however, cytokines can also damage tissue. A cytokin tower denotes the uncontrolled release of inflammatory cytokines in response to infection or other factors. This irregular and excessive release of cytokines causes heavy tissue damage and worsens the severity of the disease. It is one of the main causes of multiple organ failure and acute respiratory syndrome and is an important factor in growth and severity of COVID-19.
Vitamin D3 COVID dosage
COVID risks are lower for healthy vitamin D mirrors, especially at recommended 10,000 to 40,000 IE and 200-240 ng / ml serum concentrations. These cans and concentrations are not recommended, but make it clear that more appropriate doses and concentrations are required.
Vitamin D deficiency is associated with a weakened immune system and can strengthen cytokine towers. Therefore, researchers assume that a vitamin D deficiency can increase the risk of heavy COVID 19 complications and that vitamin D supplements reduce the risk of cytokine towers and uncontrolled inflammation in people with COVID.
Research shows that a vitamin D supplementation can prevent respiratory infections, especially in people with vitamin deficiency. Recent research shows suggest that a high vitamin D mirror may help people with Covid-19 to avoid adverse consequences. However, we do not know if the intake of vitamin D preparations reduces the risk of COVID-19. Talk to your doctor about taking Vitamin D preparationsto strengthen your general immune response.
