Derived from tea leaves, L-Theanine is a unique amino acid that is known to induce feelings of relaxation without causing sleepiness or fatigue. Theanine is found essentially in tea leaves, but it can also be found in a certain type of edible mushroom. If you’ve ever wondered why so many people say that enjoying a cup of tea relaxes them, it has much to do with this beneficial amino acid. You can ramp up your intake of this feel-good amino acid by taking a natural supplement like L-Theanine, which can reduce feelings of anxiety and stress so your mind and body can experience the calming relief it needs.

Because L-Theanine is an excellent supplement for managing stress and anxiety, it also assists with sleep issues. It can help you feel calmer and more relaxed without the need for medications like Xanax.

Medications such as Xanax and almost every other medicine that is used to treat insomnia will actually disrupt your sleep quality. Ambien is also a classic example of this. You want both sleep quantity and sleep quality. These medicines may help with sleep quantity but they actually create worse sleep quality.

So if you’re looking for a natural way to create calm in your life, give L-Theanine a try.
