Evidence continues to indicate that your vitamin D levels play an important part in immune function in general, but also specifically against COVID-19. A new study found that people who regularly use vitamin D supplements have 34% lower risk of COVID-19 infection. Those who test positive and are vitamin D deficient have a 14.73 times higher risk of DEATH. I personally take 2,000 IU daily. 1k in a D3 pill every morning and 1k in my multivitamin every night.

I suggest taking 4,000-10,000 IU daily as long as your symptoms are present and your wife and kids should be supplementing as well, if they aren't already.
