Jarrow Formulas Theanine Description

  • Promotes Relaxation
  • Supports Learning Ability
  • Neurologically-Active Amino Acid
  • Suntheanine®

Theanine 200 is a unique amino acid found almost exclusively in green tea that exerts beneficial effects on brain metabolism. Theanine induces relaxation without causing drowsiness, as measured by increased generation of alpha-waves. Theanine may improve learning ability and sensations of pleasure by affecting dopamine and serotonin neurotransmitters in the brain. Also, theanine exerts protective effects on the brain by mitigating glutamate toxicity.

Jarrow FORMULAS Theanine 200 is 100% L-theanine, made enzymatically from amino acids and is identical to the theanine found in green tea.


Take 1 capsule per day with water or juice on an empty stomach or as directed by your qualified health care professional.

This product works well for me. I take 1 capsule every night. It contains the same substance that is in green tea. April 16, 2015
Subtle relaxant Good for sleep. Works subtly. Doesn't work like prescription sleeping tablets, but does a somewhat decent job at relaxing you, and doesn't seem addictive although beneficial effects seem to diminish after using on a daily basis for a long time. June 13, 2010
Okay product This product is okay. It does not seem to work as well as similar products have for me. November 5, 2008
calm and collected This supplement helps keep you calm and yet does not dull your mind. It is subtle but effective. Works better than Kava or other relaxers that are overly strong. October 7, 2008
