Uplift your mood with the amino L-theanine


What is L-theanine?

L-theanine is an amino acid that is found mostly in high concentration in green tea leaves. It was identified by Japanese scientists in 1949. While green tea is the most common dietary source for L-theanine, this compound is also found in some types of mushrooms.


How does L-theanine uplift your mood?

L-theanine promotes feelings of relaxation and facilitates an uplift in your mood by changing a number of chemicals in your brain, namely it:

  • Boosts levels of GABA and other calming brain chemicals. L-theanine elevates levels of GABA, as well as serotonin and dopamine. These chemicals are known as neurotransmitters, and they work in the brain to regulate emotions, mood, concentration, alertness, and sleep, as well as appetite, energy, and other cognitive skills. Increasing levels of these calming brain chemicals promotes relaxation and can help us destress, focus and also improve sleep.

  • Lowers levels of “excitatory” brain chemicals. At the same time, it is increasing chemicals that promote feelings of calm, L-theanine also reduces levels of chemicals in the brain that are linked to stress and anxiety. This may also be a way that L-theanine can protect brain cells against stress and age-related damage.

  • Enhances alpha brain waves. Alpha brain waves are associated with a state of “wakeful relaxation.” That’s the state of mind you experience when meditating, being creative, or letting your mind wander in daydreaming. Alpha waves are also present during REM sleep. L-theanine appears to trigger the release of alpha waves, which enhances relaxation, focus, and creativity. One of the appealing aspects of L-theanine is that it works to relax without sedating. That can make L-theanine a good choice for people who are looking to enhance their “wakeful relaxation,” without worrying about becoming sleepy and fatigued during the day.


Benefits of supplementing with L-theanine
  • Improving sleep - With its ability to increase relaxation and lower stress, L-theanine can help with sleep in a number of ways. L-theanine may help people fall asleep more quickly and easily at bedtime, thanks to the relaxation boost it delivers. Research also shows L-theanine can improve the quality of sleep—not by acting as a sedative, but by lowering anxiety and promoting relaxation.


  • Helping maintain a healthy weight - The anti-anxiety and sleep-promoting abilities of L-theanine may help people to maintain a healthy weight. After all, getting enough sleep and limiting stress are both key to sticking with a healthy diet and avoiding weight gain. L-theanine may also play a more direct role in weight maintenance. There’s scientific evidence indicating L-theanine may help to limit fat accumulation and weight gain as well as protect against obesity.


  • Reducing stress and anxiety - L-theanine is what’s known as an anxiolytic—it works to reduce anxiety. Some anxiolytics, such as valerian and hops, have sedative effects. L-theanine, on the other hand, promotes relaxation and stress reduction without sedating. L-theanine can help foster a state of calm, attentive wakefulness. L-theanine has positive effects on both the mental and physical symptoms of stress, including lowering heart rate and blood pressure.


  • Improving focus and attention - Sometimes, L-theanine is used with caffeine to enhance cognitive skills. Studies show that combinations of L-theanine and caffeine can improve attention span, enhance the ability to process visual information, and increase accuracy when switching from one task to another.
