 Green Tea plants |
| DESCRIPTION: | Amino acid
L-theanine is the predominant amino acid in green tea and constitutes between 1% and 2% of the dry weight of green tea leaves. L-theanine is considered the main component responsible for the taste of the tea, which in Japanese is called umami. L-theanine is a derivitave of glutamine. |

| FUNCTION: | Used for promoting relaxation and modulating (improving) mood. Theanine may also enhance learning ability. These effects are perhaps achieved by increasing the level of neurotransmitters such as gamma-aminobutyric acid (GABA), serotonin, and dopamine.
Theanine may have usefulness in cancer treatment, specifically, aiding the body's response to chemotherapy - in both the effectiveness of the drug treatments and ameliorating their side effects. |

| SOURCES: | Green tea plant (Camellia sinensis) | |
| DOSAGE: | Will vary by product and formula concentration. | |
