I had great results with Equilibrant for Coxsackii (lab confirmed) also. IIRC the labs were PCR tests. Positive for Coxsackii on the first test, negative on the second test after three months of Equilibrant. My Coxsackii levels were not sky high, just high. More severe infections may not respond as easily to Equilibrant.
I took a relatively small dose of Equilibrant -- no more than 2 pills per day, I think. That may have helped me avoid the side effects some people have. I stayed on the Equilibrant for another 6 months or so to make sure we had well and truly knocked down the Coxsackii. We do this because I typically relapse as soon as I go off an anti-pathogen med (abx, AVs) if we use a more typical length of treatment.
A serendipitous discovery was that Equilibrant eliminated my chronic URI-type symptoms -- sore throat, coughing, wheezing, rough voice, congested ears and nose -- you know the sort of thing. For years, I spent 9months of the year looking, feeling, and sounding like I had a cold. My GPs ran basic tests and found nothing. All that cleared up (the symptoms, not the GPs' incompetence) with Equilibrant.
I didn't realize at first that it might have been the Equilibrant that helped. I just didn't get the symptoms around Sep like a usually do. Then I went off the Equilibrant thinking I was done. Whoa, all the URI stuff is back. So I went back on Equilibrant. The symptoms went away. I actually tested like this two more times in the next 18 months with the same results. For the moment, I'm concluding the Equilibrant is the reason my URI-type symptoms are gone. Now I take one or two pills daily for most of the year.
Before anyone starts tossing "Placebo!" around (oh wait, that individual is not posting here), I had absolutely no thought of the Equilibrant effecting those symptoms. I didn't even think of the Equilibrant when the symptoms first went away. I was looking everywhere else for the reason. I tested it multiple times with the same results. That's not a large, double-blind, placebo-controlled study, but it's good enough for me to make a decision for myself.
Equilibrant is not too expensive if you only take one or two pills per day.
