The acute effects of L-theanine in comparison with alprazolam on anticipatory anxiety in humans
Notes for this study:
| Effect | None |
| Trial Design | doubleblind |
| Trial Length | 1day |
| Number of Subjects | 16 |
| Sex | mixed |
Relative to placebo, both Theanine and the active control (1mg of Xanax) failed to modify anticipatory anxiety after acute usage. However, theanine was able to promote relaxation as assessed by the tranquil-troubled subscale of the VAMS (self-report survey).
