IMPORTANT NEW VITAMIN D FOR COVID STUDY. There have been several studies showing a relationship between Vitamin D intake and Covid - long story short - having your levels correct makes an ENORMOUS difference in risk and outcome should you contract Covid-19. This body of evidence has been strengthened even more but a full randomized controlled clinical trial - the gold standard in research and WOW.
The first randomized controlled trial (RCT) of vitamin D in COVID-19 has just been published (https://www.sciencedirect.com/science/article/pii/S0960076020302764?via%3Dihub) The results are astounding: vitamin D nearly abolished the odds of requiring treatment in ICU. Although the number of deaths was too small to say for sure, vitamin D may actually abolish the risk of death from COVID-19..
You should ALWAYS take Vitamin D with vitamin K2 which is the fat-soluble version of K. K works synergistically with D to make sure calcium goes where it is supposed to - into your bones - not your tissues or arteries.
Ideally get your levels checked and then supplement - you can get a blood test or a finger stick test and neither require a prescription. You want your blood levels between 40 - 80 ideally. The only way to KNOW this is testing. For most Caucasians who do not get much sunlight you will need to take 5,000iu per day of Vitamin D3 to get into this range, but it can vary considerably based on genetics. I require 10,000iu per day in winter months to stay there. People of color require even more. Sunlight can and does create D in most people very well, but you have to be careful of getting burned.
Now is the time to be getting your levels optimized as we head into fall and winter - do not let those levels drop! There are many other benefits to optimizing D levels including cardiovascular health, bone health, muscle mass in aging adults, etc. This list is long and impressive - single most important supplement to get right!
