Benefits of Theanine The primary use for Theanine is to reduce stress and anxiety. Reports from people who have used Theanine and the doctors who have studied its effects in their patients suggests that Theanine is effective as a treatment for:
- diminishing symptoms of PMS
- improving learning performance
- heightening mental acuity
- promoting concentration
- supporting the immune system
- lowering blood pressure
- increasing formation of the inhibitory neurotransmitter GABA
- increasing brain dopamine levels among other positive benefits with no known
downside.
- helping in the treatment of cancer
The relaxing nature of Theanine
A recent study found that the overwhelming majority of visits to the doctor's
office were related in some way to stress or anxiety. Blood pressure, immune
response, heart disease, and cancer have all been connected to stress, either
as a cause or as a contributing factor. We can lower the body's stress levels
by learning to relax and using proper nutrition. Part of that nutrition may
include Theanine, a main ingredient of tea. The stress-reducing properties of
Theanine can help alleviate most conditions in which stress is a major factor.
Theanine and Caffeine
Much of our stress is self-induced. For example, people all over the world consume
large quantities of caffeine everyday, in coffee, caffeinated teas, chocolate,
and in other products. Caffeine is a powerful stimulant, and too much caffeine
can result in tremors, headache, and sleep loss. L-Theanine appears to counteract
the effects of caffeine, providing calming, relaxing sensation. In animal experiments,
Theanine reduced stimulation caused by caffeine.
Theanine and the Immune System
One of the ways the immune system works to protect the body is by "remembering"
various bacteria. The immune system also uses latent memory, or natural defenses
to disease that are already built in. Research into the role Theanine may play
in the human immune system indicates that this amino acid may provide a bridge
between the two systems, allowing the immune system to respond more effectively.
The researchers concluded that, "This unique combination of innate immune response
and immunologic memory shows that gammadelta T cells can function as a bridge
between innate and acquired immunity. In addition, these data provide an explanation
for the health benefits of tea." Additional research on tea containing Theanine
conducted at Harvard Medical School confirmed that Theanine appears to bridge
the gap between innate and adaptive or acquired immunity.
Theanine Lowers Blood Pressure
Studies have shown that Theanine can lower spontaneously occurring hypertension,
or high blood pressure. Spontaneous hypertension is the result of stress, excitement,
or shock. The calming, soothing effects of Theanine appear to offset this dangerous
condition, significantly lowering blood pressure in animal studies.
Theanine and Cancer
Much of the research about green tea and Theanine comes from Japan. Japanese
residents who consumed green tea had much lower incidence of liver, pancreatic,
breast, lung, esophageal and skin cancers than Americans. Research on the effects
of Theanine on cancer continues. For now, it can be said that Theanine appears
to work with cancer medications, making them more effective against the disease.
Research on mice found that an injection of Doxorubicin (Adriamycin) alone failed
to slow tumor growth. However, the combination of Theanine and Adriamycin significantly
reduced the tumor weight by 62% on average.
Other studies have confirmed that Theanine found in green
tea can suppress tumor growth and proliferation,,
especially when used in combination with Doxorubicin.,
,
Theanine also helps patients who are undergoing chemotherapy for cancer treatment.
Although chemotherapy can provide hope for cancer sufferers, at times it seems
that the cancer treatment is almost worse than the disease. Researchers in Japan,
where green tea with Theanine has been a part of the culture for centuries,
found that patients experienced positive results from drinking tea. Patients
who added Theanine to their diet experienced fewer and less severe side effects
from Doxorubicin treatments. The doctors in the study felt that drinking green
tea could encourage cancer chemotherapy and may improve the quality of life
of clinical patients. |
