Theanine
In short, Theanine is health food for the brain.
Also known as L-Theanine, it is found in the world’s most popular
beverage second to water – green and black tea! Discovered in Japan in
1949, tea laboratories there found a way to extract it from the leaves
of the kyokuro plant that contain high amounts of Theanine. The
United States too have discovered trace amounts of Theanine in edible
mushrooms. It is manufactured in tablet form and taken as a dietary
supplement.
The properties of Theanine primarily affect the functioning of the
brain where alpha wave activities influence the mental state of
relaxation. It promotes calmness, relaxes the mind without inducing
drowsiness, and helps to relieve
anxiety and
stress.
It increases the production of the hormone dopamine which is
responsible for the feelings of well-being. It can also be used as a
natural remedy to anti-anxiety medications since it has the ability to
cross the body’s blood-brain barrier, a protective filter that prevents
certain compounds from entering the brain. As a substitute it
eliminates side effects, specifically drowsiness, that is commonly
associated with these medications. It protects the brain cells from
damage and begins the repair process by producing proteins that are
necessary for new cell growth.
A Chinese study has shown that drinking tea and maintaining a high
level of Theanine reduces the risk of a stroke by 40%, and counter-acts
its negative symptoms such as
memory loss
and brain tissue damage. Theanine, in combination with caffeine, has
been found to boost mental capabilities by improving creativity,
concentration and alertness, speed and accuracy in certain mental
tasks, and reducing distraction during a memory exercise - all without
the jitters of high caffeine intake. Though studies have primarily
focussed on its
stress-relieving and calming agents, they do not preclude other possible health benefits ranging from cancer and
stroke prevention to weight loss. Green tea also contains antioxidant that fights cancer and
heart disease. Research with mice have found that Theanine successfully shrink tumours and lower blood pressure.
Many people innocently speak of having “a relaxing cup of tea”
without the knowledge that their state of mind really is affected by
the Theanine in their tea!
