L-Theanine is a naturally occurring amino acid that is typically found in green tea and black tea.
L-Theanine acts as a nootropic that amazingly has the dual effect of improving mental focus, while also minimizing your response to stress.
Interesting to note, L-Theanine normally creates a relaxed, sleepy state. However, when it is combined with caffeine, it has the opposite effect and improves alertness and concentration.
As a nootropic, L-Theanine provides greater visual acuity, greater muscle dexterity, significantly increased mental focus, self-reported alertness, better reaction times to stimulus, better memory recall, and longer natural attention span.
How it Works:
L-Theanine increases the production of GABA, an amino acid and neurotransmitter that works to calm the mind and body.
L-Theanine also works to block L-Glutamic Acid from binding to specific brain receptors that produce the “fight or flight” reaction.
Finally, L-Theanine limits the neurochemicals which cause stress reactions and reduce mental clarity.
Other:
L-Theanine works synergistically with caffeine to modulate the stimulatory effects that caffeine can produce. It also works synergistically with L-Carnitine, L-Tyrosine, and Alpha-GPC to improve mental processing, mood, and clarity.
