L-theanine Capsules

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

    It's my first time to use L-Theanine on its own. I can feel the effect about an hour after I take it. Highly recommend it.

    Gentle Sleep and Relaxation

    Posted by Aaron Leos on 11th Jun 2021

    I find this to be an extremely effective and gentle solution to fall asleep and wake restfully! Not only is it an economical solution, but I know it's just strong enough to take even if I can't commit to a whole 8 hours of sleep!
