“What Is L-Theanine?”
L theanine is an amino acid found in plants that can be produced as teas. These teas usually come from a plant called Camellia sinensis, and can produce different types of teas that are commonly distributed in the market. Depending on how these herbs are processed can produce certain types:
1. white tea – unwilted and unoxidized
2. oolong tea – wilted, bruised and partly oxidized
3. black tea – wilted, crushed and fully oxidized.
*wilting is the process of taking away excess amount of water in the leaf which is necessary in promoting the breakdown of proteins into free amino acid and increases the availability of freed caffeine*Oxidation is highly important in the formation of many taste and aroma compounds, which give a tea its liquor colour, strength, and briskness.
These can bring about relaxation and calmness when consumed, definitely without any adverse effects. In fact, tea is the most popular beverage in the world next to drinking water.
L-theanine, also referred to as Suntheanine has undergo several test and research study and was confirmed to generate relaxation and calming of the mind and body, increases serotonin in the brain dopamine and GABA levels. This is highly recommended for individuals who are suffering from anxiety, stress, and emotional depression.
L-theanine works by crossing through the blood vessels it is capable to restrain glutamic-acid excitotoxicity; which is the pathological process where nerve cells are killed or if not damaged by glutamate and other equivalent chemicals. Glutamate stimulated neuro-toxicity is the number one reason for degenerative brain diseases like Alzheimer’s disease, Multiple sclerosis, Parkinson’s disease, ALS (Amyotrophic lateral sclerosis) , and Huntington’s disease. Thus, L-theanine helps improve one’s memory as well as learning capabilities, makes a healthier heart, reduced blood pressure and is also a great antioxidant for the body.
Research have shown that taking in at least 200 mg of L-theanine makes an individual get an excellent rest and sleep. This is because of the alpha waves are predominantly present in the occipital lobe during a relaxed moment of a person. This process is usually performed with the use of electroencephalography (EEG) and magnetoencephalography (MEG) from the back part of the head towards the top in a 30-minute interval. Alpha waves, a type of brain wave is responsible for our mind’s ability to relax, learn, have good memory and focus.
Individuals who are suffering from anxiety may avoid most of the adverse outcomes of stress with the help of L-theanine without getting sedated or dizzy. It will not trigger sleepiness nor encourage too much sleeping because this amino acid doesn’t generate theta waves inside the human brain.
