L-Theanine is a naturally occurring, non-protein amino acid found in tea that easily crosses the blood-brain barrier and can support the activation of alpha waves. L-Theanine increases levels of neurotransmitters like gamma-aminobutyric acid (GABA) and serotonin that regulate mood and relaxation. By modulating these neurotransmitters, it reduces neuronal excitability, promoting a calm and focused state. It also stimulates alpha brainwaves associated with a relaxed and focused mentality.

I don’t take the...
I don’t take the full dose because it is expensive and trying to make it last longer. Take it with a stack of 3 and it helps me relax before bed and fall back asleep easier when I wake up in the middle of the night
