How L-Theanine Works
L-theanine is an amino acid first discovered by Japanese scientists in green tea in 1949, although it’s lately been discovered that humans have been benefiting from this fascinating substance for centuries. It is an analog of glutamate and with plenty of benefits.
It’s also capable of modulating and increasing alpha brain waves being a form of L-glutamic acid. Alpha brain waves are electric impulses which produce feeling of calmness and relaxed alertness. Higher presence of these waves helps to control the over-activity of beta waves. Larger presence of beta waves creates a sense of fear and anxiety. Because of its ability to keep beta waves in check, it’s often supplemented for general anxiety disorders, social anxiety, and depression.
Another way L-theanine helps to fight off anxiety is by increasing the secretion of joy hormone known as dopamine. Increase of dopamine in the brain automatically improves the mood.
Other neurotransmitters such as serotonin, norepinephrine, and GABA are also targeted by this substance, all of which are responsible for treating anxiety. These neurotransmitters regulate different actions of the sympathetic nervous system, such as the “fight or flight” response. A sense of calmness is achieved as an inhibitory effect of this substance on the mind.
The effects on different neurotransmitters also help with other cognitive processes such as sleep and relaxation cycles, pleasure, and the brain’s reward system.
L-theanine has a unique ability to cross the blood-brain barrier, which allows it to be absorbed into the bloodstream faster, causing the substance to show results faster. This allows all effects of L-theanine to be seen at a faster rate. One huge benefit of L-theanine being able to break the blood-brain barrier is found when paired with GABA.
L-Theanine and GABA
GABA is one of the amino acids that is found to occur naturally in the body. This amino acid works to keep neurons in the brain from over-working. GABA also has other purposes, like boosting muscle growth, but its main function is to work as a neural calming agent. It is classified as an anxiolytic, which is the term given to any supplements that is capable of reducing anxiety symptoms. GABA supplements have also been created by scientists in an attempt to fight anxiety symptoms. However, there is one small problem. When GABA is taken orally as a supplement, it fails to cross the blood-brain barrier, thus limiting its effects compared to natural GABA.
But, L-theanine and GABA can work harmoniously. We have already discussed that L-theanine is psychoactive, which means it can break the blood-brain barrier and be absorbed in the bloodstream fast. GABA can then do its job, and the L-theanine also stimulates GABA production. This is one of the major reasons why L-theanine is so effective in fighting off anxiety and depression.
What is the Right Dosage of L-Theanine?
While L-theanine is really helpful in treating anxiety, taking this supplement in the right amount is extremely important. The dosage isn’t the same for everyone. Various factors like body weight, sensitivity, symptoms of anxiety, etc., are the factors that matter when determining the right anti-anxiety dose of L-theanine.
You will want to start with a small dose of somewhere around 50 mg to 100 mg. This is the same dosage used in the supplement Cognishield. The effects of L-theanine are generally felt somewhere around the 60-minute mark. Don’t jump through the dosage amount too quickly. You must properly assess your physique and your health status in order to decide just how much L-theanine your body requires. Regularity of this supplement is the key to maintaining proper brain health. So, your best bet is to take low doses, but at a regular time interval for maximum effects. Doing so will equip your brain with the right neurochemicals and your neurotransmitters will be stimulated regularly. Taking this supplement in a proper way means you don’t have to worry about the risk of side effects, also you can avoid having to spend your hard-earned money on prescribed medications.
While L-theanine has been proven to be highly effective for anxiety, users have expressed different opinions on what the effects of this supplement are. Many users have expressed that taking higher doses of L-theanine, around 400mg produces a more relaxing effect, and can even encourage feelings of sleepiness and fatigue. However, it’s not to say that lower doses aren’t effective, in fact, there are plenty of users who are happy enough taking lower doses. Those who take higher doses for extra relaxation also agree that even lower doses help them to concentrate better and for longer hours without the feelings of panic and nervousness. It can be stacked with either Phenylpiracetam or Noopept to help bring a feeling of calmness to balance the intensity of these nootropics.
What is L-Theanine?
L-theanine or Theanine is an amino acid, present only in green tea. A larger percentage of the amino acid needed by the body to function effectively are either produced in the body system or readily available in our diet. This isn’t the case for L-theanine. It’s a very rare amino acid found only in tea leaves and some fungal species. What this implies is that; if you want to enjoy the benefits that the amino acid offers; then you have to source for it through supplements. The aim of this article is to discuss in details what L-theanine supplement does and also offer a good recommendation on the best L-theanine supplements in the market. L-theanine has an enantiomer, the D-theanine.
Very few research work has been done to examine the effectiveness of the D-theanine since the most prevalent type is the L-theanine. Even though D-theanine is less discussed, it’s been shown that they are usually present in most theanine supplements; albeit in minute proportion. One of the unique characteristics of L-theanine is its ability to cross the blood-brain barrier; which is like a filter that prevents the absorption of materials into the brain cells. The structure of L-theanine is very similar to a neurotransmitter called glutamate. Glutamate is an excitatory neurotransmitter. The ability of L-theanine to cross the blood-brain barrier makes it an antagonist on glutamate receptor. It also increases the level of serotonin; an inhibitory neurotransmitter. This results in various psychoactive effects, which will be discussed in details in later part of this guide.
Benefits Of L-Theanine Supplements
Fix For Stress and Anxiety: The major reasons why people take L-theanine is to calm their nerve against anxiety. If you’re prone to anxiety, then you would want to take less of caffeinated drink and opt for theanine. The supplement is capable of interacting directly with the brain cells to reduce the presence of glutamate which is an excitatory neurotransmitter.
Improve Cognition and boost mood: L-theanine has been associated with the increase in alpha brain wave during the scan. Research has also shown that alpha brainwave is associated with increased creativity and reduces depression.
Inhibit Glutamate Excitocity: Accumulation of glutamate in the cell usually result in excitotoxicity due to the excessive stimulatory action of the neurotransmitter. Since L-theanine is similar in structure with glutamate, then it shares it’s receptor by binding with them as an antagonist, thereby reducing the overall impact of the neurotransmitter on the cell.
Improve sleep quality in people with ADHD: Although not a sedative, the supplement has been reported to improve quality of sleep by getting rid of anxiety and making user calm; especially in those with ADHD.
Improve learning and memory: It’s been reported to have a direct impact on the learning and memory of users. This is explainable based on its ability to cross the blood-brain barrier and act as a psychoactive. There are other benefits such as treatment of stomach cancer, asthma etc, but the effect is not well documented in these cases and the further test must be conducted before it becomes an ascertained fact.
What is the Right Dosage OF L-Theanine
Drug or supplement dosage depends on a wide range of several factors, from body weight to tolerance, as well as age. However, based on general consensus, from frequent users; it’s been reported that 200mg is the average dose required to elicit the desired effect.
This explains why taking green tea does not give the desired result. Because a typical cup of green tea contains just about 25mg of L-theanine, to get the desired result that supplement will give, about 8 to 10 cups of green tea must be consumed to attain the average dosage. It’s important to take note that tea does not just contain L-theanine, it has other ingredients as well, such as caffeine
There have been reports that taking this supplement alongside caffeine gives a whole new level of experience. It’s important to understand your body system before you load up on dietary supplements generally. Ask questions when you’re not clean about the ingredient of a particular product and go the extra mile getting the answer before taking the supplement.
