The genomic activity of vitamin D has significant effects on metabolism and physiological functions, particularly in relation to viral infections such as COVID-19. This review examines the correlation between vitamin D deficiency and increased risks of severe COVID-19 and respiratory distress syndrome. Clinical trials have tested vitamin D supplementation with promising results. Additionally, a biochemical analysis explores the antioxidant and anti-inflammatory functions of vitamin D and its influence on different biochemical pathways in the body's defense against viral infections.
The genomic activity of vitamin D is associated with metabolic effects, and the hormone has a strong impact on several physiological functions and, therefore, on health. Among its renowned functions, vitamin D is an immunomodulator and a molecule with an anti-inflammatory effect, and, recently, it has been much studied in relation to its response against viral infections, especially against COVID-19. This review aims to take stock of the correlation studies between vitamin D deficiency and increased risks of severe COVID-19 disease and, similarly, between vitamin D deficiency and acute respiratory distress syndrome. Based on this evidence, supplementation with vitamin D has been tested in clinical trials, and the results are discussed. Finally, this study includes a biochemical analysis on the effects of vitamin D in the body's defense mechanisms against viral infection. In particular, the antioxidant and anti-inflammatory functions are considered in relation to energy metabolism, and the potential, beneficial effect of vitamin D in COVID-19 is described, with discussion of its influence on different biochemical pathways. The proposed, broader view of vitamin D activity could support a better-integrated approach in supplementation strategies against severe COVID-19, which could be valuable in a near future of living with an infection becoming endemic.
