L-Theanine Powder – How It’s Made, How It Works
Related Topics
L-Theanine powder is primarily extracted from the leaves of green tea. It also appears in some wild edible mushroom species.
The compound is a naturally occurring amino acid. When ingested, it has psychoactive properties as a result of being able to cross the blood-brain barrier.
Once inside the brain, L-Theanine interacts with the neurochemistry of the brain in several important ways.
L-Theanine helps lead to increased GABA production. GABA is the primary inhibitory neurotransmitter in the brain, and is a regulator of chemical activity within the brain. This neurochemical inhibits excessive firing of neurons, leading to calm, relaxed states of mind. GABA stimulates alpha waves, electrical impulses that accompany states of deep relaxation and balance high energy beta waves.
Additionally, L-Theanine is a GABAergic compound, meaning that it can interact directly with GABA receptors in a way similarly to GABA itself.
L-Theanine also increases production of the neurotransmitter Serotonin, which is tied to emotions like happiness and contentedness. It also stimulates the release of Dopamine, another powerful chemical messenger within the networks of the nervous system.
L-Theanine is available in the United States as a dietary supplement only, and the FDA has not approved L-Theanine as a drug to prevent or treat any conditions.
L-Theanine Effects
A great way to understand the effects of taking bulk L-Theanine powder is by comparing the effects of drinking coffee vs green tea. Both provide energy and make it easier to focus upon tasks. But whereas the caffeine in coffee often provides an initial jolt of energy, caffeine together with L-Theanine in green tea offers a gentler lift and a more refined mental effect.
As coffee leaves the system, it often delivers a corresponding crash to the adrenals, which we feel as fatigue, frustration, and headaches. Green tea tapers off almost imperceptibly.
Similar to green tea but intensified, L-Theanine powder creates an organic feeling of focus, calm, and subtle energy. It can ease or prevent feelings of panic or fear, making it possible to approach work and social situations with easy confidence.
How To Take L-Theanine Powder
L-Theanine powder, whether taken in pill form, or scooped from bulk containers, is intended to be consumed orally. As a pill, it may be swallowed immediately, with or without food. As a dry powder, you can take the intended dose sub-lingually, holding it under the tongue until it fully dissolves.
Some people like to add L-Theanine to beverages, such as green tea. However, it has been noted that the powder does not blend well in liquids, and will take shaking or extra stirring to dissolve. In any case, most people enjoy the taste, which has a light umami flavor. In fact, L-Theanine was often used as a flavoring agent for other foods after it was first discovered in Japan in 1949.
L-Theanine Dosages
Proper dosage is dependent on many different factors including age, weight, and the purpose for taking a supplement. It is recommended that you speak with your doctor to determine the best dosage for your needs. The following dosage guidelines are general recommendations only, and your personal dosage may be different.
It’s important to calculate the right dose of any nootropic powder. Sometimes a difference of 50 milligrams will create effects of very different intensity. So, investing in a milligram scale is probably a good idea, especially if you plan on buying bulk L-Theanine.
Luckily, L-Theanine is a very benign and tolerable supplement, with no risks or side effects to speak of. If you take too much for your body, the compound’s water solubility ensures that your body can easily flush it out, negating the possibility of overdose.
The standard starting dose of L-Theanine powder is 50-100 milligrams. This is the minimum amount at which most users report experiencing mild effects. At these lower doses, L-Theanine’s effects tend toward calm, concentrated focus. You will remain alert and attentive to work and thoughts, without any of the hyperactivity or jitters associated with a cup of coffee.
If these effects are too mild, you may increase the dosage in increments of 50 milligrams until you achieve the desired benefits. At higher doses between 200-400 milligrams, L-Theanine delivers its most powerful relaxation benefits. This dose is more appropriate for acute anxiety attacks and similar high energy imbalances.
Taken 30 minutes before bedtime, L-Theanine is also one of the nootropics that can help with sleep.
Cost of L-Theanine Powder
Unlike some capsules, pills, and liquid formulations of supplements, most nootropic powders are very economical and suitably priced for everyday use. A 50 gram bottle of pure L-Theanine, containing 250 doses at 200 milligrams per dose, generally sells wholesale for as little as $15.
While powdered supplements are sometimes available in standard brick and mortar stores, bulk L-Theanine is typically available from online suppliers for even deeper discounts.
L-Theanine powder is a safe, easy to use supplement that helps bring all of the systems of the body and mind into balance, with no side effects or long term effects to worry about. The feeling of calm focus it provides is the perfect springboard for a confident, worry-free day.
