No complaint whatsoever, product works as expected.
ND's L-theanine has the expected umami taste and gives a calm mind. My wife regularly takes this at bedtime and wakes up well rested allowing her to function optimally during the daytime.

Build Your Stack
Unlock your full potential by building a supplement stack tailored to your unique goals. 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 with coffee
Have this with my morning coffee for clean no jitter energy.
-
Dependable
I've tried a few different sources of l-theanine, and I take it regularly. One in the morning with a stimulant, and with alcohol to mitigate the hangover. The l-theanine caps from nootropics depot do not disappoint.
-
Couldn't get much better than that
Potent product and a fair price on top of it. Actually domestic options for me are much more pricey without much guaranty about potency.
-
Extremely Potent
This product and the other product I purchased from Nootropics Depot (KSM-66) are extremely potent. Specifically referencing the L-Theanine, it is the most potent formula I have ever used, more potent than Suntheanine product I have tried from Amazon.

lax bro
Theanine helps wiht focus, lightens the "negative" effects of caffiene, and can help you relax or even feel more rested if taken before bed. Its a really good deal price wise, especially if you take advantage of the $50+ free shipping in USA. Great add on to any stack. no cons, only pros.

Great product
I ordered this from Colombia and, so far, I'm satisfied with the results. L-theanine relax you, but it doesn't make your mind fuzzy. I totally recommend it.
