- "the amino acid theanine, which is found in green,
black, and oolong teas, causes a decrease in the brain's "alpha rhythms" when
people perform complex attention tasks, causing them to pay closer attention.
His ongoing research, funded by the food and beverage conglomerate Unilever,
suggests that theanine and caffeine together improve performance more than
either substance alone ... in mice, at least—tea's main antioxidant shows an
ability to curb brain cell death and encourage neurons to repair themselves"

"several lines of evidence have converged to solidify the concept that
stress makes us fat (because of cortisol), thins our bones (because of cortisol), shrinks our brains (because of cortisol), suppresses our immune system (because of cortisol), saps our energy levels (because of cortisol), and kills our sex drive (because of cortisol) ... Take a daily
multivitamin/multi-mineral supplement - because calcium, magnesium, vitamin C and B-complex vitamins are needed for a proper stress response ... Chief among the supplements with documented

"Theanine is an amino acid found in green tea. It helps to produce a calming effect in the brain and induces a feeling of relaxation and well-being. Best of all, it does all of this without causing drowsiness. In fact,
studies have shown that theanine enhances the ability to learn and remember. One of the other benefits of this amino acid is that it helps to lower blood pressure naturally, by enhancing GABA in the
brain"

A
New Natural Relaxant - Life Extension Magazine, 10/01 -
"Theanine readily crosses the blood-brain barrier of humans and exerts subtle changes in biochemistry. An increase in alpha waves has been documented, and the effect has been compared to getting a massage or taking a
hot bath. Theanine is different than kava-kava in that it doesn’t cause drowsiness. And unlike tranquilizing drugs, it doesn’t interfere with the ability to think ... Theanine increases GABA, while caffeine decreases it.
GABA doesn’t just relax, it also creates a sense of well-being. Theanine’s ability to increase this brain
chemical can put you in a better mood by changing biochemistry. Theanine also increases levels of dopamine, another brain chemical with mood-enhancing effects"
