Coffee and energy drinks release caffeine into your body instantly, giving you a spike of unsustainable energy for up to 45 minutes, with a crash at the end. This usually makes you feel jittery or anxious. This is MASSIVE stress on your body, which causes an increase in stress hormones, such as cortisol.
When L-theanine (a rare natural amino acid) binds with the naturally occurring caffeine found in Matcha Fuel, the L-theanine slowly releases the caffeine into your body for a period of up to 6 hours, so there is none of that jittery anxiety associated with coffee consumption. This results in all-day sustainable energy, and an increase of alpha-brain wave activity, which leads to a state of relaxed alertness and clean lucid focus that is unparalleled by any other “energy drink”.
L-theanine has been shown to benefit patients diagnosed with anxiety by increasing levels of dopamine and GABA in the brain. In fact, one 2008 study published in the Asia Pacific Journal of Clinical Nutrition, researchers found that L-theanine has a significant effect on the general state of mental alertness and arousal.
