Plants have many natural bioactive compounds that can and have been synthesized to prepare new therapeutics such as antibiotics, growth supplements and or even medicinal stimulants. L-Theanine is one of such plant compounds used as a therapeutic. It is an amino acid also known as 5-N-Ethyl-Glutamine commonly found in tea leaves, some types of fungi and a couple of other plants.
Its properties can, naturally, be summed up as being a relaxing agent. It is also thought to reduce stress and slightly improve attention. L-theanine does not appear to induce sleep, but it may help from people who have very mild insomnia. Those who have severe insomnia, however, should consider other lines of treatment.
L-Theanine is thought to have significant benefits for associated lifestyle diseases like diabetes, stress, cardiovascular disorders, hypertension, tumor suppression and other diseases. It is also believed to improve memory function and combat the effects of neurotoxins.
How L-theanine works
There are two types of Theanine, D, and L. These supplements are non-toxic for all mammalian cells up to a certain level. However, L-theanine is readily absorbed into the plasma membrane more than D-theanine, and it stays in the bloodstream longer. L-theanine has many beneficial effects when taken.
L-theanine doses range from 50mg to 250mg depending on the frequency. Most people take two 200mg doses a day or three 100mg doses a day since your body has a high tolerance to L-theanine with mild effects.
Theanine protects neurons from damage by inhibiting different neurological functions such as catalase, superoxide dismutase, and succinate dehydrogenase activity. This reduces GSH and oxidative damage to neural cells. It also prevents brain injury by inhibiting cerebral cortical neuron involvement in the delayed neural death.
In adults, L-theanine acts as a hypotensive agent that has anti-stress capabilities that help suppress cortical neuron excitement thereby reducing anxiety and controlling the rise of blood pressure in high-stress conditions.
L-theanine causes the rise of dopamine and hepatic glycogen. It also reduces concentrations of 5-HT and serum urea that result in the alleviation of physical fatigue. Prolonged administration reduces concentrations of 5-HT serum urea and lactate as well as increasing DA and hepatic glycogen levels.
Intake of this supplement reduces anxiety and depression preventing stress-induced impairments of long-term hippocampal potentiation and also improves recognition memory. It also reduces the heart rate and salivary immunoglobulin A thereby decreasing acute stress responses to stressing tasks. The reduced heart rate and mediates attenuation of the sympathetic nerve activation or suppression of the excitation of the cortical neuron.
Protecting the cardiovascular system
Consumption of this supplement improves vascular function thereby decreasing the risk of cardiovascular diseases. This compound can reduce cholesterol in the blood serum, increase vasodilation and produce nitric oxide. It can also protect the brain from cerebral ischemic injury. Alleviating levels of cholesterol protect the heart from coronary diseases. L-theanine also reduces levels of abdominal adipose, liver cholesterol, serum neutral fat, and cholesterol thereby leading to a healthy cardiovascular system.
L-theanine improves brain memory by promoting the maturity of the nerve cells during the neural maturation period. This is beneficial for brain development, learning, and memory activity because it helps eliminate acquired memory disorders, oxidative stress and improves the brain’s alpha waves. It also increases the levels of dopamine in the brain and helps improve its cognitive functions.
Maintaining normal sleep
Research done on a target population concluded that L-theanine significantly helped users experience a good night sleep. This could help users achieve better mental and cognitive health.
L-theanine seems to have no side effects. I certainly didn’t feel any in my five day trial period. This may, however, not mean that there are none. If you think this as the best nootropic for you, try it out and see if there are any observable side effects.
L-theanine will not cure your anxiety and should not be used in place of standard anxiety prescriptions. You should also not use this drug if you take a lot of drugs, alcohol or excessive amounts of caffeine. This drug has very mild effects and it, therefore, can’t provide any relief for patients suffering from severe cognitive or health disorders. (You should seek advice from a qualified medical practitioner)
I discovered L-theanine while looking for a solution for my mild ADHD problems. The second day is popping it I felt some slight improvements in my sleep, reduced anxiety, and better memory. A few days into my self-medication I noticed that the medication was not strong enough to improve my ADHD. I needed something stronger.
I discovered when going through reviews on Reddit and Web MD that many users with mild attention and sleep disorders reported good results with L-theanine. I can, therefore, only recommend L-theanine, about my experience, to people who have mild ADHD as a start so that they can see if it works for them. Those with more severe ADHD symptoms should try something a bit stronger.
