    You may have heard the name Suntheanine® and you might be wondering what exactly it is and what it does. Read on to find out why it is an essential component of our natural sleep aid supplement.

    Suntheanine® is a branded element consisting of an amino acid known as L-theanine, which is usually found in natural sleep assistance supplements. L-theanine, also commonly referred to as theanine, is an amino acid found in tea leaves.

    Widely regarded for its profound ability to produce soothing, sedative effects, this ingredient is also known to enhance concentration and cognitive skills. Seen as the premier brand for L-theanine supplements, Suntheanine® is a 100% pure form of L-theanine. Suntheanine® is the most thoroughly studied form of L-theanine and has been tested in several human clinical trials to support its safety and effectiveness.

    Clinical trials have shown Suntheanine® to promote an alert state of relaxation without drowsiness, as indicated by an increase in Alpha brain waves, and a decrease in Beta brain waves.*

    The brain emits weak electrical impulses that can be measured on the surface of the head, which are classified based on their frequency:

    How Is It Made?

    Suntheanine® is manufactured through a patented fermentation method that imitates the natural process found in green tea leaves, generating the purified L-theanine ingredient. The potency of Suntheanine is far greater than that found in nature, so you can reap the benefits of L-theanine without having to drink unrealistically large quantities of green tea.


    What Are the Effects?

    Suntheanine® incites a reaction in the brain identified as alpha waves, which are connected with a calm, but conscious state of mind. In addition to boosting the creation of alpha brain waves, this product also promotes the reduction of beta brain wave movement, which is typically associated with experiencing an active, restless mental state. These characteristics make Suntheanine the ideal supplement for individuals seeking to maintain a positive mindset accompanied with a focused spirit. As a natural sleep aid, Suntheanine can also help individuals who have difficulties becoming relaxed at night.


    How Does It Work?

    Because Suntheanine® promotes relaxation and soothes the brain, it is an excellent means of improving sleep quality and ensuring a sound night’s sleep on a regular basis. In essence, Suntheanine® assists you in calming your brain down to get you ready for sleep. Since many people in the U.S. have issues with sleeping – over 1/3 reporting they do not get the recommended 8 hours at night – this supplement offers an effective solution to a nation deprived of adequate sleep.

    What Makes It Different from Other Types of L-Theanine?

    • Suntheanine® is a trademarked, patented product backed by 100's of clinical studies, whereas generic types of L-theanine do not have related patents and do not have the support of clinical research.
    • Almost all of the research conducted on L-theanine was done utilizing Suntheanine brand, which makes it the most extensively researched form of L-theanine.
    • Suntheanine® holds an FDA GRAS (Generally Recognized as Safe) Affirmation, while other brands do not have the safety and toxicity data necessary to ensure product safety.
