L-theanine is #1 recommended by http://www.reddit.com/r/nootropics/faq http://www.reddit.com/r/nootropics/faq

  I've been taking L-theanine with my coffee for a few years now. It has a noticeable positive impact on my ability to focus and think clearly. I also feel a lot more comfortable taking it than other nootropics, because a) it's just a naturally-occurring amino acid, b) I'm not aware of any negative side effects reported from using it.

  Worth mentioning but hardly comparable to Provigil

    Not even the same ballpark. L-theanine is meant as an addition to high levels of caffeine to reduce the negative effects of caffeine.

  From the FAQ: "Most studies done on the l-theanine-caffeine combination have a l-theanine to caffeine ratio that isn't consistent with ratios you would expect from most teas. The studies used about twice as much l-theanine as caffeine by weight. The ratio found in most teas is reversed, with the possible exception of high quality green tea. Tea also increases fluoride intake which may lead to skeletal or other health problems when consumed in excess." I'd just like to put in a word for good deep-steamed sencha (fukamushi-cha), and for special occasions the more expensive gyokuro. Brew it properly and it's very, very delicious, and the effects are just lovely. You easily get four brewings from one dose of tea leaves. I drink it most days at work and it's such a delight!

  Creatine (monohydrate) is another very beneficial supplement for most people. It has well-studied mental benefits if you don't get a lot of dietary creatine (mainly red meat). Tip: it'll dissolve nicely in your hot coffee.
