Theanine 100 mg, 60 Caps

Jarrow Formulas

  • $ 15.95

Theanine is an animo acid found in green tea. It has a calming effect on NMDA receptors (those receptors shared by calming GABA and stimulating glutamate), so I often prescribe this if a patient has high glutamate on a neurotransmitter test. It also helps to push alpha brain waves, which are "calm yet alert", or good for creativity. 

Recommended Dose:  1 cap, 1-3 times daily.
