A nootropic stack, simply put, is combining two or more supplements that have beneficial effects on memory, learning, focus, or motivation, to create a synergistic effect in the brain greater than any increase in cognition than the supplements you “stack” could provide on their own.
So you if you take a nootropics stack or have done research into how they work, you’ll know that L-theanine is often a core ingredient in a successful stack as it helps to tackle both your physiological and psychological stress responses. It also promotes alertness, leaving you in a calm, focused state.
L-theanine is a unique amino acid that can easily cross the blood-brain barrier and affect the central nervous system. Studies have shown that L-theanine directly stimulates the production of Alpha brain waves
Brain waves are weak electrical impulses emitted by your brain that can be measured on the surface of the head. The predominant frequency of these electrical impulses correlates with different types of mental states.
Brain waves are classified into four categories (Delta, Theta, Alpha, and Beta), each with an associated mental state.
Stimulants, like Caffeine, promote Beta waves and suppress the others, leading to increased stress, anxiety, and over-excitement. It can be very difficult to focus and concentrate when you are emitting Beta waves. Delta waves are only seen in the deepest stages of sleep and Theta waves are seen in light sleep and drowsiness.
The all-important Alpha waves are present during wakefulness where there is a relaxed and effortless alertness, which L-theanine provides seamlessly.
