L-theanine is one of the main active ingredients found in green tea which reduces anxiety and promotes focus and relaxation without the drowsiness. It has a synergistic effect when taken along caffeine which means there is no brutal crash or jitters after consuming it and this leads to sustained mental energy, better focus, alertness, cognition, and productivity.
How does L-theanine induce relaxation?
Researchers have identified that L-theanine works by increasing the production of dopamine, serotonin, and other neurotransmitters in the brain. Furthermore, it induces relaxation by improving alpha-wave activity in the brain.
Benefits and Studies
Synergy with caffeine: In comparison to supplementation of caffeine by itself, the addition of L-Theanine to the caffeine was able to positively impact parameters of accuracy and attention when it came to cognitive testing in healthy adults.
Stress buster: L-theanine suppresses stress hormones that can negatively affect mood, memory, and learning. This is indicative of L-theanine’s neuroprotective properties.
Improved sleep quality: According to a Japanese human study, L-theanine enhanced sleep quality. Participant testimonials indicated that L-theanine supplementation enhanced exhaustion recovery and feelings of being refreshed.
Improved alpha waves: Alpha waves are known to be associated with a state of relaxation. One study conducted by Unilever showed that L-theanine supplementation promoted Alpha wave production in the brain (confirmed by EEG) that translates to improved relaxation and attention, improved cognition, better mood, and cognitive performance.
Improved blood flow: L-theanine improves blood flow by increasing nitic oxide formation in the blood vessels.
NEXTGEN coffee infused with L-theanine is the smartest way to enjoy the performance enhancing benefits of caffeine while eliminating its undesirable effects.
