L-Theanine supplementation is an excellent method to help you relax and worry less. L-Theanine is an amino acid that is typically extracted from green tea. It is similar in structure and has many of the same effects as Glutamate, a neurotransmitter in the brain that is involved in learning and memory. There is no evidence of toxic effects from supplementing L-Theanine and it is considered safe when taken by mouth for short-term use.
L-Theanine, also simply known as Theanine, was discovered as an element of green tea back in 1949. L-Theanine has shown a number of benefits, including stress and anxiety reduction, healthy blood pressure promotion, and memory improvement. L-Theanine has also been shown to promote significant cognitive improvement in alertness, arousal, and attention.
There is further evidence suggesting that L-Theanine may have antioxidant and anti-aging effects, although this is still being studied. Lastly, many individuals choose to supplement L-Theanine with a form of Caffeine, as this combination has been shown to improve cognitive speed and accuracy and reduce distraction during attention switching tasks.
