Covixyl Success I have been using Covixyl since December of 2022. I have found it to be very helpful in preventing illnesses caused by bacteria or viruses. I have not experienced any colds, coughs, or flu - or COVID - during these last 8 months. I am immune compromised - and I usually use a mask when indoors with other people, but I have been protected on the few occasions when I had to remove my mask - such as at the dentist office - or the 2 or 3 times I ate indoors at restaurants. I also use a small (7"X3"X3") portable air purifier - which also helps. For those who are immune compromised, I strongly recommend Covixyl.

Not available elsewhere except America Bought 6 packs when I was vacation in the states last summer. I wanted to purchase more but could not find it elsewhere. They don't ship them overseas and also not available oversea.
