RE: My 82-year old former landlady used Quercetin and Zinc to beat COVID in about 9 days
Bless her heart. Did you ask her what dosage she took?
I bought her 300 mg capsules and Zinc w copper from Whole Foods (at the time sold out everywhere else). Had her take 2 Q caps, and zinc 30 minutes later. Also had her take Bromelain with the Quercetin and it greatly helped her arthritis.
