How It Works
How L-Theanine Zen Works
L-Theanine, the primary active ingredient, is an amino acid found primarily in tea leaves. It promotes relaxation without causing drowsiness by:
- Increasing Alpha Brain Waves: L-Theanine promotes the production of alpha brain waves, which are associated with a state of relaxed alertness and creativity.
- Modulating Neurotransmitters: L-Theanine influences the levels of neurotransmitters such as GABA, serotonin, and dopamine, which play a role in mood, sleep, and relaxation.
- Reducing Cortisol Levels: Studies suggest that L-Theanine may help to reduce levels of cortisol, the body's primary stress hormone.
Magnesium Bisglycinate supports muscle relaxation and nervous system function, further contributing to the calming effects. Lemon Balm Extract has traditionally been used for anxiety and sleep improvement. Vitamin B6 is essential for the synthesis of neurotransmitters, optimizing brain function and mood regulation.
