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

    • Potentiates GABA*
    • Promotes relaxation*
    • Support healthy sleep cycles*
    • Support healthy stress levels*
    • Promote feelings of well-being*
    • Support cognitive function and focus*
    • Synergistic effects with Caffeine*

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.

    I wouldn’t use this by itself

    Posted by Mike on 2nd Feb 2024

    Don’t know what good this product will do unless you can mix it with caffeine. Alone it makes me sleepy.

    Staple nootropic in my stack, EXCELLENT quality

    Posted by Feilisha on 23rd May 2023

    I'll make this short and sweet: I've tried about 3-4 different brands of L-theanine (both powder and capsule forms) and ND has the BEST quality of L-theanine. I usually take this on an empty stomach with coffee in the morning and it has caused no issues for me and is a staple in my nootropics stack. I thought I just could not tolerate L-theanine b/c of nausea from other brands, but once I bought from ND, I have had no issues.

    L-theanine

    Posted by Joe on 27th Oct 2022

    This stuff is great. I use a capsule press to make even doses. It takes away the jitters and anxiety you get from caffeine and increases your focus.

    Best L theanine I've tried

    Posted by Kristian on 5th Aug 2022

    Love this L theanine, some of the best I've tried. Works great in a stack and reduces daily stress and helps you relax. Great product. Not as anxiolytic as Lemon Balm but they pair great together with their GABA synergy

    Helps me sleep

    Posted by Joe on 30th Apr 2022

    I suffer from insomnia and after purchasing the l-theanine powder, I mix a little bit into water and drink it and hour before bed and I’m eased into a restful sleep. Nothing else I have found helps me actually fall asleep, so I am very grateful for this product.

    Affordable Quality

    Posted by Shawn on 6th Apr 2022

    I get a boost of focus and energy from theanine. Definitely doesn't help me sleep. Other people report the opposite, so your results may very. It's super inexpensive considering the number of servings per container. Dissolves instantly in water and has almost zero taste.

    Great product

    Posted by Aimee Andersen on 26th Jun 2021

    As usual, another great product from Nootropics. I use a very small amount in my coffee every morning. I literally can't drink coffee without it, the caffeine affects me so much. This product is brilliant at taking away the coffee jitters.
