آیا ویتامین D خطر ابتلا به کرونا را کم می کند؟
Vitamin D is a fat-soluble vitamin that plays several important roles in your body.
Vitamin D for proper functioning of your immune system is the body's first line of defense against infection and disease.
This vitamin plays an important role in coping with the disease. It has both anti-inflammatory and immune regulator properties and is vital for activating the body's defense system.
It has been proven that vitamin D boosts the function of immune cells, including T cells and macrophages that protect your body against pathogens
In fact, this vitamin is very important for immune function so that small amounts of vitamin D are associated with increased susceptibility to infection, disease and disorders related to the immune system.
For example, low levels of vitamin D are associated with an increased risk of respiratory diseases, including tuberculosis, asthma and chronic obstructive pulmonary disease (COPD) as well as viral and bacterial respiratory infections
In addition, vitamin D deficiency is associated with decreased lung function, which may affect your body's ability to fight respiratory infections
However, a recent study has determined that a level of vitamin D of 30 ng/ml of blood helps reduce the likelihood of adverse clinical outcomes and death in hospitalized patients with corona.
In the study of hospital data, 235 patients with corona were as follows.
In patients over 40 years of age, compared to patients with vitamin D deficiency, those with adequate levels of vitamin D had a 51.5 percent lower chance of having adverse consequences such as unconsciousness, oxygen deficiency and death.
A recent survey involving 11,321 people from 14 countries found that vitamin D supplementation reduces the risk of acute respiratory infections (ARI) in both those with low and adequate vitamin D levels.
Overall, the study found that vitamin D supplements reduce the risk of acute respiratory infections by at least 12 percent. The protective effect was strongest in those with low vitamin D levels.
In addition, the study showed that vitamin D supplements have a greater effect if consumed daily or weekly at low doses, and if consumed at longer intervals with higher doses, they have less effect.
It has also been shown that vitamin D supplements reduce mortality in older adults, who are more at risk of developing respiratory diseases such as corona.
Although research continues in this area, it is important to understand that taking vitamin D alone cannot protect us from contracting COVID-19.
However, vitamin D deficiency may increase your susceptibility to infection and disease by damaging immune function.
