I mix my kava and fill up water bottles so that I can take it to work, when I first started taking kava, I used the Gaia Herbs Kava Phytocaps, they were great for the RT part but once I felt the now familiar kava high, (for lack of a better term) and finished the capsules, I started buying powder and have not looked back. I had to take 6 capsules before whereas now it takes 1-2 tbs per 8 fl oz for a much, much better effect.
