I ALWAYS have this in my house!
This product is simply amazing. I have been using it the last couple of years and am completely sold on it. Last winter, that nasty flu came through our house and I took this religiously, 5 times per day. The other three in my family were knocked out by it and I was in close contact with all of them and yet I was the only one who didn't fall ill. I did have days where I had mild chills so I knew my body was fighting it off but I just kept up the Virogone for about a week - 10 days. I think the key is to use it with regularity. My husband was only having it once or twice a day and he still got sick and was wiped out for a good 2 weeks.
Anyway, I now will always have a bottle in the house so I can start taking it the minute I feel I am coming down with something.
