Energy drinks tap into benefits of L-theanine
In an attempt to create the next generation of energy drinks, companies are increasingly looking into an amino acid found in tea, called L-theanine, to enhance concentration and focus. Preliminary studies suggest the substance might calm the brain to increase concentration and mental stamina, instead of a quick energy boost currently provided by caffeine and taurine. L-theanine is readily absorbed in large quantities, crosses the blood-brain barrier and gets into the brain fast. Products such as SoBe lifewater, Vitamin Water, ViB and new Gatorade drink Tiger, all contain L-theanine.
