So far no effective treatment has been found for coronary COVID-19 or any other means of prophylaxis other than spatial distancing and good hygiene practices. Also, no studies have been conducted to prove whether vitamin D deficiency or dietary supplements have a positive or negative correlation with contamination of the individual by the new coronavirus COVID-19.
However, there are several studies linking vitamin D deficiency to an increased risk of developing respiratory diseases and poor immune function. In addition, studies show that vitamin D supplements can boost the body’s immune response and protect against respiratory infections. More specifically, a recent review of 11,321 people from 14 countries found that using vitamin D supplements reduced the risk of acute respiratory infection (ARI) in both those who were deficient in vitamin D and those with adequate levels. Overall, the study showed that vitamin D supplements reduced the risk of developing at least one ARI by 12%. The protective effect was stronger in those with low levels of vitamin D. At the same time, the review found that vitamin D supplements were more effective in protecting against acute respiratory infection when taken daily or weekly in small doses and less effectively when doses, at longer intervals.
In addition, taking vitamin D supplementation has been shown to reduce mortality in older adults, who are at higher risk of developing respiratory diseases such as COVID-19. As mentioned at the beginning of the text, it is important to remember that there is no scientific evidence that taking vitamin D supplements can protect a person from developing COVID-19. However, vitamin D deficiency can increase your susceptibility to general infections and diseases by damaging immune function.
This is a worrying fact, as we know that a large proportion of the population is deficient in vitamin D, especially for older people who are at higher risk of developing more serious COVID-19-related complications. Considering the above, it might be a good idea to check your vitamin D-25 (OH) D3 levels to determine if you are deficient in this important nutrient.
Depending on the test results, a daily intake of vitamin D supplementation from 1000 to 4000 IU is usually sufficient for most people. However, for those with extremely low blood levels, much higher doses may be needed to increase their levels to an optimal range.
It is noted that although the recommendations vary regarding optimal vitamin D levels, most experts agree that optimal vitamin D levels are between 30-60 ng / mL (75-150 nmol / L).
