Theanine, L-Theanine

Theanine is an amino acid found exclusively on Camellia sinensis (green tea) being the one compound that confers its flavor. Theanine characteristics include relaxing agents, stress reduction and focus enhancement.


  • Origin Plant Based
  • Source Green Tea
  • Type Amino Acid, Nootropic

Cognitive Function and Brain Health

Cognitive functions are brain skills divided into: memory, perception, language, executive functions, attention and praxis (ability to perform complex movements). These functions depend on healthy synapses and neurons, which require good overall brain functioning. Supplements can affect cognitive function directly or indirectly. Direct effects can alter or participate in neurotransmissions and influence the brain's energy metabolism. The indirect effects include hormonal changes that affect the brain, and improvements in cognitive disorders such as anxiety, depression and insomnia.
  • Focus & Attention

    Attention is the behavioral and cognitive process of selectively concentrating on a discrete aspect of information, whether considered subjective or objective.
  • Age Range Teenagers (13-19), Adults (20-59), Seniors (>60)
  • Toxicity Not toxic
  • Side effects No adverse side effects reported untill now
  • Warnings Low Blood Pressure, Hypertension Medication

Why be Careful

Theanine might decrease blood pressure. Individuals who have tendency to have low blood pressure should be cautious when consuming theanine.
