Vitamin D: a potentially important secosteroid for coping with COVID-19

Area of Science:

• Immunology
• Nutritional Science
• Virology

Background:

• COVID-19 has caused significant global mortality, necessitating rapid and cost-effective therapeutic approaches.
• Vitamin D, recognized for its immunomodulatory properties, has demonstrated potential in mitigating acute respiratory tract infections, including COVID-19.

Purpose of the Study:

• To review experimental, observational, and clinical studies on vitamin D's role in viral infections, particularly COVID-19.
• To explore the relationship between vitamin D, the Renin-Angiotensin System, and cytokine storms in reducing COVID-19-related inflammatory lesions.

Main Methods:

• Compilation and analysis of existing research on vitamin D and viral infections.
• Examination of studies focusing on COVID-19 patients and vitamin D levels.
• Inclusion of data on vitamin D pathophysiology, metabolism, sources, and recommendations.

Main Results:

• Vitamin D exhibits a protective effect against inflammatory lesions in COVID-19 patients.
• Adequate vitamin D levels are associated with a reduced risk and severity of COVID-19.
• The review highlights vitamin D's influence on the Renin-Angiotensin System and cytokine storm modulation.

Conclusions:

• Vitamin D plays a significant protective role in combating inflammatory processes associated with COVID-19.
• Maintaining sufficient vitamin D levels is essential for decreasing infection risk and mitigating disease severity.
• Addressing vitamin D deficiency is vital to prevent severe COVID-19 complications and support overall immune function.
