I've been using quercetin and a "Super C" vitamin from costco that has C, D, and zinc in it. In the last 3 years whenever I've felt something coming on I take quercetin and one of those vitamins. After 12 hours I take ivm and another vitamin. Most of the time the first dose does the job. Twice I took the ivm. Only one time in the last 3 years I ended up getting a sinus infection but that's a chronic problem I have from allergies.
