How it works

L-theanine is a member of a class of compounds related to glutamine, another amino acid that is responsible for several mechanisms in the brain. L-theanine can work to either enhance or block some of these pathways that would normally use glutamine.

In fact, it’s likely that 25% of those following a typical western diet aren’t consuming enough. Source: Klevay, L. M. (2011). Is the Western diet adequate in copper? Journal of Trace Elements in Medicine and Biology, 25(4), 204–212.

It’s absorbed in the small intestine, enters the bloodstream, and can then cross the blood-brain barrier.

It can increase serotonin, dopamine, and GABA levels in the brain. These are neurotransmitters that can promote general wellbeing.

L-theanine selectively binds to glutamate receptors in the brain, reducing stress and having a neuroprotective effect.

The case for supplementation

As a naturally occurring amino acid found in tea and some mushrooms, L-theanine is regarded as generally safe for human consumption with no adverse effects reported with supplementation.

L-theanine supplementation could be beneficial for someone experiencing:

  • Poor sleep quality
  • High stress, anxiety, or an inability to relax
  • Lack of focus
