For an athlete, it seems to good to be true. A "sports supplement" that increases alertness, concentration, reaction time and focus while decreasing muscle fatigue or at least the perception of fatigue. It can even shorten recovery time after a game. HGH? EPO? Steroids? Nope, just a grande cup of Juan Valdez's Best, Liquid Lightning, Morning Mud, Wakey Juice, Mojo, Java, aka coffee.
Actually, the key ingredient is caffeine which has been studied repeatedly for its ergogenic (performance-enhancing) benefits in sports, both mentally and physically. Time after time, caffeine proves itself as a relatively safe, legal and inexpensive boost to an athlete. Or does it?
