I take, daily, 100mg Caffeine, 200mg of L-Theanine (as Suntheanine), and 500mg of Rhodiola Rosea (3.6% rosavin 18mg, 0.9% salidrosides 4.5mg).

This is a fairly effective regimen, for me, for combating fatigue and maintaining focus. I simply keep a bottle of Suntheanine and another of Rhodiola Rosea at my desk and eat them with my morning water or tea. I haven't done any rigorous testing to prove to myself that these things are helping, but I am certainly convinced that they do.
