Again, there are different options for different people, but you also have to consider the type of people who may be interested in taking a nootropic (student, businessperson, etc). Many of these people rely on energy drinks/shots or store-bought coffee, which can all be VERY expensive. Giving them a nootropic product that can replace their expensive caffeine source at a better price, while also providing far superior results (with effective doses of several nootropic ingredients) is a good thing, and the amount of caffeine isn't so high as to be prohibitive to having more caffeine/coffee during the day, either at another time or at the same time. Remember, studies have shown that 3-5 cups of coffee can be a "good" thing, and that comes out to a maximum of 350-600mg, depending on the caffeine content of your coffee, with the range being about 70-120mg per cup. The inclusion of a decent dose of caffeine can be big for someone looking to be able to take a nootropic without breaking the bank or allocating even more money to their energy/supplement budget; it seems possible that many people would rather replace one serving of their caffeine (energy drink, coffee, etc) than add another thing/supplement (a nootropic product) to it; saving money AND getting better results/effects instead of spending more money to get better results. There’s also a convenience factor here that many people, especially people who aren’t as involved or used to taking a plethora of supplements, in being able to take 1-2 pills for their energy, focus, cognitive, etc needs. It’s very easy to keep a few pills with you for the day and take them whenever you feel you need them, whether it’s when you’re on the go, at work, in class, etc. Also, it seems that people are enjoying it even at one capsule, which is only just a bit more than 1 cup of coffee, and I think I recall some loggers taking it with coffee and/or other things that contain caffeine.
