L-Theanine is a nootropic supplement which helps with focus, relaxation, and stress relief. L-Theanine is found in tea leaves in low concentrations (less than 2%), which means that efficient and optimal dosage levels cannot be delivered from drinking tea. During rest, L-Theanine increases alpha activity in your brain thus making you more relaxed. L-Theanine has structural similarity to Glutamine and both neurotransmitters that are produced from it (GABA and glutamate) and is known to reach the brain and act in the brain following oral ingestion. A combination of L-Theanine and caffeine is noted to be synergic in promoting cognition and attention. The most important part is that it has no sedating effects.
It has been noted that L-Theanine is metabolized in the kidneys via the independent phosphate variant of the enzyme glutamines, and is not affected by the phosphate-dependent version a similar metabolism as Glutamine. Orally administered L-Theanine supplementation can cross the blood-brain barrier.
In individuals with diagnosed schizophrenia given 400mg L-Theanine in addition to standard antipsychotics, eight weeks of supplementation was able to reduce positive and general psychopathology symptoms and anxiety. Both green and black tea are known to be associated with vascular responsiveness. L-Theanine seems to promote nitric oxide formation.
This product can also come in handy for individuals who suffer from social anxiety. Many users have reported that this product helped them with their social skills and general shyness.
The benefits of L-Theanine
One of the biggest advantages of this product is that it can bypass the blood-brain barrier, which allows it to reach the brain and provide psychoactive benefits. L-Theanine can reduce stress and increase relaxation and enhance the brain function, especially when taken with caffeine. It can increase the levels of GABA, dopamine, serotonin, which is why it’s so effective against anxiety and depression. Serotonin is a so-called “happiness hormone” and Dopamine is a hormone that causes you to feel good. Dopamine is released during pleasurable activities such as eating or sex. Increased intake of L-Theanine promotes both of these hormones presence in your body.
It’s also been shown to improve the immune system and help you to battle with flu, cold, and other diseases. One study demonstrated that theanine could reduce neuronal cell death in brain cortex and hippocampus. The same study showed that theanine reduced oxidative protein and lipid damage and the elevation of glutathione levels in the brain. In conclusion, theanine might be useful in the prevention and treatment of Alzheimer’s disease. One more thing makes theanine significant because it elevates the glutathione levels; it makes a great anti-hangover supplement.
L-Theanine can also fight high blood pressure by relaxing the body. Also, one study shows that theanine inhibits nicotine-induced dependence, making it a legitimate strategy for tobacco addiction treatments.
The side effects
L-Theanine is one of the safer nootropic supplements. It has almost zero side effects. According to numerous studies and doctors, theanine does not interfere with other drugs or supplements. Although it’s safe, this product contains Suntheanine which may induce complications. Be sure to contact your physician before purchasing and using this product. Also, pregnant and nursing women should avoid this product, as well as children.
A recent analysis of nine different studies on stroke and theanine consumption found that the more tea people consumed, the less risk they had for a stroke. That’s not to say L-Theanine is the protective factor, but it has a similar chemical structure of glutamate, a cell-damaging substance released during a stroke. One of the hypotheses is that L-Theanine’s presence may block glutamate receptors during a stroke thus limiting brain damage. It is also possible that other ingredients of green tea work in synergy with theanine.
It is note-worthy to mention that unlike other anti-anxiety treatments, L-Theanine did not increase drowsiness, slowed reflexes, and impaired concentration. The Journal of Functional Foods published an article where they said that results of a present study showed that ingestion of 200mg of L-Theanine changes the electrical activity in the brain by increasing alpha electric band measured by EEG.
This product does not contain gluten, dairy, egg, peanut, fish, soy, shellfish, wheat, yeast, fillers, binders, preservatives, or magnesium stearate. Suntheanine has been clinically proven to promote an alert state of relaxation without drowsiness, as indicated by an increase in Alpha brain waves.
Suntheanine is a patented pure form of L-Theanine. It naturally stimulates activity in the brain (also known as Alpha waves), which are associated with a relaxed mental state. It is not an extract from green tea but rather is produced via a fermentation process that mimics the natural process in green tea leaves, resulting in 100% pure L-Theanine. If you take a moment and check other nootropic reviews, you’ll see there aren’t many of them with patented technology of extracting pure elements of green tea. The FDA approved Suntheanine in 2007.
The bottle comes with sixty 200mg capsules. As a dietary supplement, adults take one pill daily on an empty stomach or as directed by a healthcare professional. This means one bottle should last two months. You can find it on Amazon for less then $30 not including the promotions and discounts.
