Vitamin D may reduce the risk of severe COVID-19 (Coronavirus Disease-2019). Individuals with vitamin D deficiency should consider supplementation to maintain optimal levels and support immune function against viral infections.
Area of Science:
- Immunology
- Nutritional Science
- Public Health
Background:
- The COVID-19 pandemic, caused by SARS-CoV-2, necessitates strategies to mitigate infection severity and mortality.
- Vitamin D deficiency is associated with increased susceptibility to viral infections, including COVID-19.
Purpose of the Study:
- To review the potential roles of vitamin D in reducing COVID-19 infection risk and severity.
- To explore mechanisms by which vitamin D modulates the immune system against infections.
Main Methods:
- Literature review of clinical and epidemiological studies.
- Analysis of scientific literature on vitamin D's immunological functions.
Main Results:
- Vitamin D deficiency is linked to higher COVID-19 risk and severity.
- Vitamin D influences innate and adaptive immunity, potentially offering protection against viral infections.
Conclusions:
- Individuals at risk of vitamin D deficiency should consider supplementation to achieve optimal levels.
- Further research is warranted to confirm vitamin D's role in reducing COVID-19 incidence and mortality.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
