What is L-theanine?
Theanine is derived from tea leaves. Tea is native to eastern Asia and is a member of the Theaceae family. This evergreen shrub or tree grows to over 9 m in height and is pruned from 60 cm to 1.5 m for cultivation. Its dark green, serrated-edged leaves are alternate and oval, while its white and fragrant blossoms appear singly or in clusters.
L-Theanine has mood-modulating activity,anti-cancer,diminishing symptoms of PMS,improving
learningperformance,heightening mental acuity-neurotransmitter,promoting concentration,acting antagonistically against the paralysis induced by caffeine,supporting the immune system,lowering blood pressure,increasing brain dopamine levels among others.
L-theanine Benefits
L-theanine works as a nootropic by providing an increase in alertness and attention while still acting as a relaxing aging. Studies show that prolonged use of L-theanine can also be beneficial for memory, but the primary effects are utilized for short-term neurotransmitter alteration including increased GABA and serotonin. Even students with ADHD using L-theanine improve their ability to focus.
Ample evidence proves L-theanine works synergistically to negate the side effects while amplifying the benefits. Anxiety and jitters caused by are reduced by L-theanine supplementation. We provide an extra strength capsule that provides 200mg of 99% pure L-theanine per capsule. The benefits of sublingual solution is better and faster absorption that largely bypasses the first pass metabolism.
L-theanine Mode of Action
1) Stress
Theanine may help reduce the negative effects of stress, according to a small study published in Biological Psychology in 2007. In an experiment involving 12 people, researchers found theanine-treated participants were less likely to experience an increase in heart rate when performing a stressful task.
2) Immunity
Taking green-tea-derived theanine and antioxidants in supplement form may help prevent the flu, suggests a study published in BMC Complementary and Alternative Medicine in 2011. Every day for five months, the study's 197 participants took either a placebo or a capsule containing theanine and catechins (a class of antioxidants found in green tea).
3) Brain Health
A 2010 study from Nutritional Neuroscience suggests that a combination of theanine may help improve cognitive performance. For the study, 44 young adults took either a placebo or a combination of theanine prior to performing a demanding cognitive task. Researchers found that the combination of theanine significantly improved accuracy and alertness and helped to increase focus while performing the task.
Additionally, findings from an animal-based study published in Free Radical Biology & Medicine in 2009 suggest that theanine may inhibit buildup of amyloid beta (a substance that forms the brain plaques associated with Alzheimer's disease).
4) Depression
Theanine may help relieve depression, according to an animal-based study published inPhytotherapy Research in 2011. In tests on mice, scientists discovered that theanine produced an "antidepressant-like effect."
5) Weight Loss
Theanine shows promise as a weight loss aid, according to animal-based research published in the journal In Vivo in 2004. In an experiment involving mice fed green tea powder, researchers found that theanine found in the powder appeared to prevent weight gain and fight the buildup of fat.
L-theanine Dosage
The recommended dosage for L-theanine is as little as 100mg. The capsules are considered extra-strength in the the dosage is 200mg/capsule. However, the effects of L-theanine are felt in dosages as low as 50mg and young adults take between 50 - 400mg per day. The safety and low chance of toxicity allows for higher doses in some individuals. The average green tea drinker gets around 20mg of L-theanine per day.
Taking L-theanine is effective with to 2 L-theanine ratio. With a regular 8 ounce cup of coffee, there are 100mg suggesting 200mg L-theanine should be supplemented.
