Current Evidence of Vit D effects on Covid-19

While most of the news today is about the vaccine and when it will be available, I have been looking at research to determine how to keep myself healthy throughout the pandemic. Now that the vaccine is rolling out, it may still be a while before everyone can get it. In the meantime, a simple and affordable way to reduce the symptoms is to take Vitamin D. This has been on my radar for a while, and though I am not the best at taking it daily, the following evidence is showing it is well worth it!


Vitamin D has been reported to mitigate the symptoms of common cold and influenza (Rondanelli et al., 2018) Though the Covid virus is different, there are similarities in the presentations of the respiratory illnesses.


Therefore, several authors have emphasized the preventative use of vitamin D in the COVID-19 management (Wimalawansa, 2020; Grant et al., 2020c; Braiman, 2020).


The main concern I have is the dosing. "Thus, from the literature, it is reasonable to suggest taking 10,000 IU/day for a month, which is effective in rapidly increasing circulating levels of 25(OH)D into the preferred range

of 40–60 ng/mL. To maintain that level after that first month, the dose can be decreased to 5000 IU/d [135,139,140]." According to this article, we need to be doing a significant amount over normal daily dosages to get blood levels high enough to help mitigate the symptoms.

Your doctor is important in managing your levels to prevent toxicity.



Furthermore, this newly published article confirms what has suggested back in April that Vit D supplementation is an important factor in the effects of covid-19 on the body.
