I was very happy with iherb.com's bussiness including speedy delivery. However, after taking caprylic acid for a week, I noticed that they had an effect similar to caffeine on my system. I felt anxious and jittery so I discontinued use -- same reason I don't drink coffee. I imagine if you are used to the side effects of coffee then the caprylic acid will not bother you.
