I found it very effective in minimizing the symptons of a cold or flu that I get every season. Also the delivery quality was super fast and reliable. When it is in stock, then it comes very fast. Sometimes it is sold out, so I have to wait for it a while. But when it is in stock, then there is no problem getting it shipped to me immediately. I haven't tried other brands of Epicor, but since I started with this one, I have stuck with it because the results seems to be very helpful for my overall health. I also got my family to start using it, and they also say that it has helped their overall immune system by not having too many strong symptons when they do get the common cold. I just have to remember to take it every morning, and even when I miss it by a day, I still feel the positive effects. I have no idea what ingredient is in it that helps, but at least it is easy to take, has no smell, and so far has not had any side effects. I just wish that there were larger sized containers on offer here so I don't have to throw out so many bottles after just using the smallest ones they offer here...it's just not as environmentally friendly. When they were out of stock, it was also very convenient that they notified me as soon as it came back in stock so I did not have to log in every day to check on whether or not it came back in stock. I guess this is a time saver of sorts. The gel capsules are very easy tot ake, so that makes the experience of taking everyday very easy as well.
