Move over, chamomile. These science-tested sips leave you more focused, less frazzled.

Jones GABA is a non-caffeinated tea and juice blend that features GABA (gamma-aminobutyric acid), an ingredient that helps rev the production of calming alpha brain waves and decrease beta brain waves, which are linked to nervousness. Grab it at a store near you.

Slow Cow calls itself the anti-energy drink. It contains L-Theanine, which is supposed to help you relax without causing sleepiness. Research suggests the ingredient can also improve your ability to learn and memorize new information. The beverage is only available in Canada for now, but will hit U.S. shelves soon.

Red Espresso isn't your normal cuppa joe--it's actually caffeine-free rooibos tea that you brew in a coffee maker or espresso machine. The ruby-hued brew packs more than 5 times the amount of brain-sharpening antioxidants as green tea and fans swear it eases insomnia, reduces anxiety and soothes digestion. Find it at Whole Foods or order it here.

THANKS!

All teas need to be freshly steeped to receive the most benefits. Also, the steeping process itself is very important, and different steeping methods have been compared in research studies investigating the health benefits of green tea.

Much of the research on green tea has focused on its polyphenol content. Many different kinds of polyphenols are found in green tea, and these polyphenols will become increasingly present in the tea water the longer a tea is steeped. (This principle holds true for green tea, white tea, black tea, and oolong tea.) Catechins, theaflavins, and thearubigins are among the best studied of the green tea polyphenols that are known to increase in the tea water as steeping times increase.

Given an equal amount of steeping time, loose leaf teas do a better job of passing on their polyphenol content than bagged teas because loose leaf teas expose their whole leaves to the steeping water during the entire steeping time. Bagged teas, by contrast, may float on top of the steeping water and expose less of the tea leaves directly to the water. (You can improve this situation by allowing the tea bag to bob down into the water from time to time during the steeping process.)

When you brew tea yourself, you can control this steeping process in a way that will maximize the polyphenol content of your tea. When you buy a bottled tea, however, you may or may not get a tea that has been carefully brewed. In addition, you are likely to get a tea that includes other ingredients and is not simply 100% brewed tea.

In 2005, the Linus Pauling Institute at Oregon State University issued a report showing that many bottled teas contained polyphenol content 10 to 100 times lower than freshly and carefully brewed teas. Differences between bottled tea and freshly brewed tea were attributed to steeping process, amount of actual tea found in the bottled products, and presence of non-tea ingredients in the bottled teas, including sugar. In addition, bottled tea companies were sometimes found to use powdered rather than brewed tea in their products.

If you do choose to make bottled tea a regular part of your diet, be sure to find a manufacturer who produces a high-quality bottled beverage. You can find unsweetened, organic green teas in bottled form in some natural foods stores and on the Internet; these teas will provide you with health benefits closer to those offered by freshly and carefully steeped tea.
