Green tea's theanine comes into focus

Beverage makers are focusing in on a substance in green tea that improves mental focus and alertness:

Loaded with caffeine and taurine to stimulate the central nervous system, energy drinks have become the go-to solution when you need a quick, energizing pick-me-up.

But sometimes energy isn't what you need. Concentration and attention can start to fade in the face of those midafternoon doldrums and a host of distractions. Something to enhance focus would do the trick.

Some beverage manufacturers say they have just the solution. They're touting a new kind of drink that emphasizes focus over ferocity. The key substance is the amino acid L-theanine, which preliminary research suggests might calm the brain to enhance concentration and mental stamina.

Green tea naturally contains just the right amounts of both caffeine and theanine, so why not get them naturally?



There exists a magical plant whose infusion contains all of the things in these bottled drinks that you need—and none of the things you don't.
