Excellent...take some vit D regardless.
I'm on 3000IU D3 per day. I was doing 6000IU daily, but that started causing some blood issues for me, so had to drop it down.
I have a strange conspiracy theory that my high dosage of quality CBD capsules, daily - to help treat inflammation in another part of my body - has utterly prevented the bug from taking root in my lungs - Dosing a few hundred MG of CBD per day across a morning and evening regimen.
I'm probably retarded, tho.
There is probably all kinds of strange correlations that exist re this infection. It would take years to unravel.
It definitely has a connection with blood and it's viscosity, at least it seems to.
