I haven't really taken it as a supplement/extract by itself, but drinking lots of strong green tea gives me distinct but different effect from coffee/energy drinks/caffeine pills.
It mostly seems to negate the negative effects of caffeine (apart from problems falling asleep) and gives a mood-boost and counteracting stress. It only goes so far of course, over-consumption of tea will still yield anxiety and dependence, but the threshold for this is a lot higher.
