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
