You can get capsules or tablets which combine zinc and quercetin.
I take 2 capsules of Zinc with Quercetin and another 2 capsules of Quercetin with Bromolain. I also take vitamin D, vitamin C, a multivitamin, B12, calcium, magnesium, vitamin K, and CoQ10. I’m 68 with mild hypertension but I presumably had Covid in March 2020. I’m not freaking out about the virus but just using common sense and practicing good medical hygiene. Better safe than sorry.
