Also known as: L- Theanine, L-Theanine
Amino acid found in tea that helps relieve stress, smooth out the stimulatory effects of caffeine, and promote nitric oxide formation
What Is It?
L-Theanine is a non-dietary amino acid that helps bring about a sense of relaxation without inducing sleep. Theanine is found predominantly in tea leaves and is responsible for tea's calming effects on the body.
What Does It Do?
As mentioned above, theanine has a calming effect on the body. For this reason, it's often included in many sleep aids and anti-anxiety formulas commonly supplemented. Clinical studies have shown that daily consumption of 200mg of the amino improved the overall quality of sleep, although it didn't increase the length of time individuals were sleeping.
Additionally, theanine also works synergistically with caffeine. Most notably, it helps to take the "edge" off the harsh stimulant kick that high doses of caffeine give some individuals. Furthermore, theanine also helps to improve the cognitive effects of caffeine yielding a stronger focus during your workouts when the two are consumed together.
Lastly, L-theanine may act as a glutamate antagonist in the body.
Why is this important?
Stress hormones (glucocorticoids) are activated by both stress and depression. Scientists have theorized thatglutamate receptor antagonists may offset the harmful effects of high glucocorticoid level byblocking certain signals in the brain activated by glutamate. This leads to a significant reduction in stress, anxiety, and even provides some neuroprotective benefits.
