I do the same regiment. However take a multi vitamin too. Also been taking a quercetin/zinc/copper combo pill. Zinc can impede on copper. If I’m feeling like something is trying to attack (sneezing, runny nose, etc.), I take extra vitamin C (a few times in an hour - body only absorbs so much), and additional vitamin D3. Sometime I take an additional zinc/quercetin in evening. Pine needle tea, curcumin, elderberry, black cumin seed/oil, etc., may be worth exploring too.
I've gotten by with about half of the D/C/Quercetin, not advocating just saying
Cool
