What dosage?
I used 500mg of Quercetin and 50mg of zinc thru the whole ordeal. Prior to contracting it, I was using 500mg of Quercetin and 30mg of zinc on a daily basis as a prophylactic. I was also on a pretty strong vitamin C and D regimen prior to contracting it. 3000IU of C and 5000IU of D3 along with K2.
