Healthy Woman LeapingWhat Is L-Theanine?

L-Theanine is an amino acid that is naturally sourced mainly from black tea and green tea. It is largely responsible for these beverages’ effects on mood and anxiety. Initial analyses revealed that L-Theanine is able to alter the level of different neurotransmitters in the brain.

The Neurotransmitters

The capacity of L-Theanine to affect different neurotransmitters in the brain has made it a good candidate as a nootropic. This quality is further enhanced by the absence of adverse side effects that are normally experienced by users of other nootropics. L-Theanine has the capacity to inhibit or enhance the functioning of the following brain transmitters:
• Dopamine – This neurotransmitter is involved in the brain pathway that plays a role in reward-encouraged behavior. L-Theanine increases production of this neurotransmitter when it enters the brain.
• Serotonin – When a person feels good out of doing something, or he feels depressed, or feels he woke up at the wrong side of the bed, this is the neurotransmitter at play. What L-Theanine does for this particular transmitter is regulate its level.
• GABA – This neurotransmitter has an inhibitory effect in the brain and is present mainly in the cortex. It regulates anxiety and contributes mainly to vision, motor control and other cortical functions. L-Theanine is an agonist of this neurotransmitter and as such, produces muscle relaxant, anticonvulsant, anxiolytic and sedative effects.

What Benefits Can We Get?

Numerous benefits have been proposed or credited to L-Theanine, but the scientific community is still in the testing stage for most of these benefits. For now, what we have is testimonial evidence and we can glean most of it from feedback of L-Theanine users.
• Sleep benefits – Many people have problems sleeping well, but those who tried L-Theanine supplements have experienced significant improvements in staying asleep and falling asleep easily. One capsule at bedtime may be all you need to improve your sleep patterns and overall sleep quality.
• For coffee users – Many people have been drinking coffee in large quantities and because of that, have been experiencing negative effects from caffeine. L-Theanine users attest to the ability of this substance to negate the negative effects of using coffee. Other users think that L-Theanine negates only the negative effects and not the energizing effect which people find very useful in coffee.
• For multitasking workers- The relaxing effect of L-Theanine has been one of its most emphasized effects. This green tea ingredient can be the best solution for people facing highly stressful days in the office.
• ADHD patients – Many parents with ADHD-affected children have found a non-dangerous alternative solution for their children. We are hearing positive reports in this aspect, but parents are advised to consult with their doctors even if they see good effects in their children.
• Cardiovascular and CNS – If there’s a need for you to find a solution for your tensed nerves or irregular heart rate, discuss with your physician whether L-Theanine can help. The inhibitory effects of L-Theanine may help a lot to improve your condition. Studies suggest using Glycine in combination with L-Theanine.

What Side Effects Can One Experience from Using L-Theanine?

Fortunately, there are no major adverse side effects identified from the use of this substance. There are mild effects such as:
• Nausea
• Headache
• Dizziness


Digestive pathway?

L-Theanine is structurally similar to glutamine and glutamate. This makes it a chemical that exhibits excitatory effects in the brain and like these brain chemicals that we have in the brain, L-Theanine is processed in the small intestine and the liver. L-Theanine can also move through the blood-brain barrier without changing its original form. Being a substance that can cross through this barrier without modifying its form has made it a potential substance that can bring about direct psychoactive effects on the person using it.

What Does Psychoactive Chemical Mean?

When people say the term “psychoactive”, they mean it is “the enhancing of the cognitive functions.” In both literature and feedback from users, L-Theanine has been proven to be effective in improving mental states with no adverse side effects.
