Build Your Stack

Whether you're focused on energy, focus, or overall wellness, we’re here to guide you in creating the perfect combination of supplements to support your journey. Your health, your way—powered by the right stack.
What is L-Theanine?
First discovered as a constituent of green tea leaves (Camellia sinensis) in 1949. L-Theanine is a non-proteinogenic amino acids and is considered a nondietary amino acid, not unlike L-Ornithine or L-Citrulline. L-Theanine is primarily known for its ability to promote relaxation without causing sleep and is often paired with Caffeine. It is thought that L-Theanine helps balance the negative effects of Caffeine that some people experience. Together, L-theanine and Caffeine are considered one of the most commonly used and popular nootropic stack options that may promote faster reaction time, numeric working memory reaction time and improved sentence verification accuracy.
L-Theanine Benefits and Uses
L-Theanine benefits and uses may include:
- Promotes relaxation*
- Support healthy sleep cycles*
- Support healthy stress levels*
- Promote feelings of well-being*
- Support cognitive function and focus*
- Synergistic effects with Caffeine*
L-Theanine Studies
L-Theanine may have positive mood-boosting effects as scientists have discovered that it changes levels of amino acids affecting serotonin and other neurotransmitters in the brain. L-Theanine may also help suppress glucocorticoids. Glucocorticoids are stress hormones that can have a negative effect on mood, memory and learning. L-Theanine may act as a glutamate antagonist and, in turn, balance the harmful effects of high glucocorticoid levels. This also suggests that L-Theanine may be neuroprotective as well.
Additionally, L-Theanine may promote better sleep. One Japanese human study where participants were given a daily L-Theanine supplement concluded that L-Theanine did not induce sleep or make them sleep longer - but rather that it improved sleep quality. Documented participant responses claimed that exhaustion recovery and feelings of being refreshed were enhanced by L-Theanine.
L-Theanine supplementation has been studied for its potential ability to reduce mental and physical stress, improve cognition, and boost mood and cognitive performance. It is also reported to promote alpha wave production in the brain. One study conducted by Unilever was able to confirm that even small amounts of L-Theanine were able to promote alpha wave production as indicated on an EEG (Electroencephalography).
L-Theanine Dosage
As a dietary supplement, take one 200mg L-Theanine capsule daily.
L-Theanine may be synergistic with Green Tea Extract.

great natural remedy, bonus is enhanced cognition
i first tried l-theanine in the hyped caffeine/theanine synergy and i liked its affect. i decided to give l-theanine a shot on its own without the caffeine and i was amazed by the results. it gave me a nice, calm, clean sort of feeling that wasn't causing me drowsiness/sleepiness in any sort. i started taking 200mg daily in the morning with my coffee and felt the synergistic effect much better with my low-caffeine coffee than that with the 100mg caffeine, and eventually started taking another 200mg dose in the evening. sometimes i would take 3x to a total of 600mg in one day. thank you guys!

Excellent Theanine
I like that the capsules are 200mg rather than 100mg and the potency is good. A good value

Good product, a little expensive on the shipping
The L-theanine was good. The shipping cost was high but the total cost was less than my last supplier. It shipped and arrived quick.

Sleep
It helps my wife shut down her mind while trying to sleep. She uses 400 - 600 mg 5 days a week and phenibut twice per week. Both have help her sleep and fall back asleep if she wakes up in the middle of the night.

Mild Calming Effect
Mild calming effect without side effects
-
Great starter nootropic. Go for the theanine+caffeine pills instead
They don't do much other than relax you (a little too much lol) if taken by themselves so definitely buy caffeine pills along with them. Easier to just get the theanine+caffeine pill combo. I take them for improving my mindful meditation practice, and overall having a baller day. A gentle

Great Product
Usually take multiple times a day. Subtle but calming and helps me sleep as well
-
Works sometimes
Works on some days. Good product though.

Good
