L-theanine Powder

L-Theanine Powder

L-theanine is considered a non-dietary amino acid, but it can still provide a wide range of potential benefits when supplemented. Read ahead to learn more about this nootropic and how you may use it to enhance cognition.

What Is L-Theanine Powder?

L-Theanine Powder is derived from Camellia sinensis--the tea plant. Black, green, and white teas all come from the Camellia sinensis plant and also provide the compound. L-Theanine is an amino acid, but it isn’t an essential amino acid or one of the more common nonessential amino acids that you might be more familiar with.

Although tea has been consumed for centuries and touted for its benefits for just as long, it was only in 1949 that L-Theanine was discovered as a constituent in green tea. L-Theanine has been used in various food and drink items in Japan since the 1960s. Perhaps surprisingly, L-Theanine can provide an umami (savory) flavor.

 

L-Theanine Benefits

L-theanine has been shown to potentiate GABA, or gamma-aminobutyric acid, a naturally occurring amino acid.


L-theanine may also encourage the release of several other neurotransmitters. These neurotransmitters can have a wide range of effects on cognitive processes, tapping into feelings of reward, pleasure, and motivation. Theanine may also promote more restful sleep cycles.
Furthermore, L-theanine may increase your brain’s alpha waves, resulting in increased mental alertness and improved focus and clarity. This may lead to greater productivity aimed at increasing motivation. Some studies have even found that increasing alpha brain waves may encourage creative thinking.

 

Why Buy L-Theanine Powder?

L-Theanine is a naturally derived supplement that has been given GRAS status by the United States FDA, meaning that the compound is generally recognized as safe.

L-Theanine Dosage

As a dietary supplement, take 100mg of L-Theanine 1-2 times daily. 

Where to Buy L-Theanine Powder

Nootropics Depot offers 125g or 500g jars of high quality L-Theanine powder. Nootropics Depot's L-Theanine has been lab-tested and verified for both product purity and identity. L-Theanine has been granted GRAS (generally recognized as safe) status in the United States.

    Good for caffeine in the right amounts

    It appears that the ideal dosage of l-theanine to caffeine can vary a lot between people. I find the typical ratio 2:1 to be too much and can make me feel lazy. A 1:1 ratio does appear to noticeably reduce the jitters from caffeine without causing lethargy.

    I tried taking it in the evening and it does help me to relax and wind down but it does not appear to help with sleep, potentially causing insomnia.

    The powder tastes mildly sweet and mixes with water well after breaking any clumps apart.

    Perfection.

    Figuring out the correct dosage was tricky at first(since too much can be sleep-inducing), but I've found that ¾ of a teaspoon is perfect for my o.m.a.d. intermittent fasting lifestyle. I'm a female working in manual labor, so the mental ease this provides me is perfection. It's this very chill vibe that's neither apathy nor confidence to the point of arrogance....More like a soothing state of self-assurance that allows me to remain calmly grounded in my body despite what occurs around me (i.e. sudden changes in schedule or others' behavior). In short, it has made me far more of an adaptable person. To think that substances labelled explicitly as "adaptogen"s haved helped me far less (i.e. stressed me out much more) in comparison to this L-Theanine. When it comes to talking I am very introverted by nature so socializing at all had prior made me so anxiety-ridden, but L-Theanine has somehow taken that stress from me. I'm finally able to say what I need to say without the crippling self condemnation. I've recently decided to start using oxiracetam as well, which essentially completes me from mind back to my now-soothed body. The both of them work synergistically with me. I've learned that most, if not all of my anxiousness and irritation was purely physiological and to focus on it via consumption is key. My digestive system feels more at ease when I am. I'm not sure if it's at ease because I am, or I'm at ease because it is, though I cannot deny that since starting with L-Theanine the difference I've noticed in my daily endurance is remarkably improved. NootropicsDepot has literally never disappointed me. Shipping is always rapid. Within 3 business days, rapid. I'm sure they must take their own supplemental regimen of nootropics to stay this consistently organized. And of course the potency is undeniable. I think I prefer the powder since I can divide out my servings, and also having a container makes scooping so much easier. Literally c a n n o t complain about any of this. Great shipping, great price, great quality. Agh, anyways. Highly recommended.

    L-Theanine

    Use every morning with my coffee and stack. Takes the edge off of caffeine and creates focus and mood improvements.

    Must have

    This needs to be in everyone's stash. I use it to ease anxious feelings, improve my mood, and it's great before bed to ensure a better night's sleep.

    Many uses!

    Great for taking the edge off of a stimulant like caffeine, relaxing your mind when focused on stressful things, helping you get to sleep when insomnia strikes for a variety of reasons!

    Glad I Found This

    Been taking L-Theanine for a while, going on 5 years. I've been buying it exclusively from another well known brand up until this last purchase. I decided to give Nootropics Depot a try to see if they had the same quality L-Theanine that I was used to. Sure enough, it looks, feels, smells, and tastes exactly the way that it should. It dissolves in water the way it should. Most importantly, it provides the effects that it should. It's prefect L-Theanine. I'm glad I switched brands, buying the 500 gram container saves me a lot of money in the long run, especially since $50+ gets free shipping. If you're thinking about trying it, go for it.

    High Quality L-Theanine

    This is a soft white powdered amino acid form of L-Theanine. I use this to balance my normal daily Nootropic/Herbal stacks, and it is a pure, high quality, form of L-Theanine. This was just one product I ordered and am reviewing. Always, you can trust Nootropics Depot, and I’m a naturally skeptical person when it comes to purchasing powders and certain psychoactive substances online. These products are consistent and are tested for purity, and it shows in the quality consistency. Sincerely, a long time connoisseur of Nootropics.

    it works, nicely sealed up when it arrived

    powder worked for me, doesn’t taste or smell bad. I was happy that it was properly sealed with shrink wrap and with a seal under the lid. would recommend

    Works great, tastes clean

    Works as expected and tastes much cleaner than a BulkSupplements batch I tried. Will only order theanine from here now.

    I love theanine

    I hate drinking coffee without having theanine to keep the edge off. Theanine helps me get good sleep and keep a stable mood during the day.

    Don't think it works for me

    It feels like I kinda imagined it working for a while so I took it a lot, but I haven't missed it since. I'm pretty sure though that it has helped me to bring down like caffeine jitterness or something of that sort.

    A must have!

    This is a must-have if you take caffeine! I use a lot of caffeine at work and this mitigates all the jitters and restlessness when I'm at my desk. I also take some before I workout to keep me focused and calm. I have mild stress and this is great when in public/ talking to people!

    Not much noticeable effect but...

    It's kinda put ur mind on an alpha wave state which is nice for learning and relaxation
    Still, it's not strong enough for me

    A Note about Nootropics Depot L-Theanine and its use in combinational trials in "set and setting"

    As noted in the literature (L-Theanine: properties, synthesis and isolation from green tea - Voung et al - SciFoodAgri 2011; 91:1931-1939), L-Theanine's properties make it an ideal element with which to experiment in combinatorial, synergistic ways. We use Nootropic Depot's L-Theanine for our work because of its high assay for purity. We are at presnt conducting small trials of combining Nootropics Depot's L-Theanine with various other materials, including oxiracetam (available here), phenibut (ditto), kavalectone extracts, high-cacao chocolate (high PEA content), bitter orange extract, and THC-9.

    Tastes like L-Theanine!

    Great quality and use it religiously with my coffee. It taste like the Theanine I've purchased from other brands & has the same slightly clumpy consistency. Again, wish it came with a measured scooper but I have plenty on hand.
