Benefits of Theanine

Theanine, an amino acid found naturally in tea leaves, is a powerful nootropic supplement with numerous benefits. On this page, we’ll take a look at what Theanine can do for you and why it’s such a powerful Amino Acid in combination with Caffeine.

What is Theanine?

Theanine is an amino acid derivative of Glutamic Acid (also known as glutamine) that is found naturally in green and black tea leaves. It was first discovered by Japanese scientists in 1949 and has since been studied extensively for its potential health benefits.

Health Benefits of Theanine

Research has shown that Theanine may have several positive effects on the body and mind including:

  • Reducing stress and anxiety levels: Studies have found that taking supplemental Theanine can help to reduce cortisol levels and other markers of stress. It may also help to improve focus and cognitive performance by reducing distractibility.
  • Improving sleep quality: Theanine has been shown to increase relaxation levels without inducing drowsiness, making it great for improving sleep quality without interfering with daytime wakefulness.
  • Increasing dopamine: Dopamine plays an important role in both physical and mental health, so increasing its production can be highly beneficial. Studies have shown that theanine can boost dopamine production, which could lead to a range of positive effects such as improved mood and increased motivation.
  • The combination of Theanine and Caffeine has been shown to have several benefits, particularly in reducing the jitters and anxiousness associated with caffeine intake. Studies have shown that the combination improves alertness and cognitive performance while reducing the unpleasant side effects such as anxiety or restlessness.

Dosage & Side Effects

It is recommended to take 50mg+ of Theanine per day but this should always be discussed with your doctor beforehand. There have been few reported side effects from taking the supplement but these are generally mild such as lightheadedness or digestive discomfort. As with all supplements, it’s important to consult your doctor before starting any new supplements to ensure they are right for you.


Overall, there are many potential benefits associated with taking the supplement Theanine in terms of mental wellbeing, relaxation, improved cognition and better sleep quality.
