“My favorite source of zinc is a liquid supplement that includes quercetin. That pairing helps drive zinc into cells making them a hostile environment for replication of SARS-CoV-2.”
I haven’t been totally convinced that the posited ionophore activity is meaningfully real and not merely theoretical. Despite taking all those I had covid four times and possibly five. But it’s true I stayed out of hospital so who knows..
When I get the very first symptoms of a cold (usually a sore throat), I’ll take up to 2,000 mg of vitamin C and 100 mg of zinc daily for a few days. Seems to help lessen the severity. I haven’t had a cold (or Covid) since retiring in 2020, probably because I’m not around that many people now.
