14 Mar Vitamin D can play a critical role in the prevention of COVID-19 related hospitalization and mortality
Studies have shown that supplementation of Vitamin D can reduce the risk of admission to an intensive care unit due to COVID-19 by as much as 33%.
Furthermore, there is evidence suggesting that Vitamin D supplementation could reduce all-cause mortality among those with COVID-19, compared to non-supplemented individuals.
The meta-analysis included 11 randomized controlled trials from around the world, involving over 16,000 participants across varying age groups and populations. The results showed a clear protective effect for individuals who took at least 10 micrograms (400 IU) per day when compared to those who did not take any supplements or took less than 10 micrograms (400 IU). Moreover, the results were further confirmed through a trial sequential analysis which showed that there was sufficient evidence to conclude that Vitamin D supplementation of at least 10 micrograms (400 IU) per day reduces COVID-19 related intensive care hospitalization and mortality.
In conclusion, these results provide definitive evidence that Vitamin D supplementation at levels of at least 10 micrograms (400 IU) daily can reduce risks of admission to an intensive care unit due to COVID-19 as well as all-cause mortality among those with COVID-19. It is therefore recommended for individuals from all age groups and populations to supplement their diets with Vitamin D in order to reduce their risk for severe outcomes if infected with COVID-19.
Allow for adequate sunlight exposure (20-30 minutes of unprotected sun exposure, several times per week) is also recommended as an additional way to get Vitamin D in order to maximize the protective effects against COVID-19 and its related intensive care hospitalization and mortality. Therefore, it is vital that individuals take precautionary measures such as supplementing their diets with Vitamin D and getting enough sun exposure in order to reduce their risk of contracting severe outcomes due to COVID-19 infection. With all this information, it is clear that Vitamin D can play a significant role in the prevention of adverse outcomes associated with the novel coronavirus.
