Description

L-Theanine Capsules Benefits and Uses

L-Theanine is very similar in structure to glutamine and GABA and is anecdotally consumed for its perceived antioxidant and relaxation effects, without promoting drowsiness. It has a strong synergistic effect with caffeine.

Chemically, L-Theanine is the enantiomer of D-Theanine, and it is a member of the glutamine derivatives class of compounds, which refers to compounds that contain glutamine or a derivative. Both L-Theanine and L-Glutamine are non-proteinogenic amino acids (not used to synthesize proteins). L-Theanine is water soluble and moderately acidic.

L-Theanine capsule supplements are also known by a few different names, including:

  • Theanine
  • 3081-61-6
  • Theanin
  • N-Ethyl-L-glutamine
  • (S)-2-Amino-5-(ethylamino)-5-oxopentanoic acid
  • N5-Ethyl-L-glutamine
  • L-gamma-Glutamylethylamide
  • N-gamma-Ethyl-L-glutamine
  • N(5)-ethyl-L-glutamine
