What does Suntheanine do in the body?

October 26, 2021

Our daily stressors seem to be increasing. We’re trying to get the kids to soccer practice on time and it’s our turn to bring the snacks. The dog gets sick as we’re rushing to work. We’re up all night worrying about that presentation due tomorrow. It’s no wonder many of us feel tired, irritable and have trouble focusing. 

Backed by numerous scientific studies, Suntheanine is a popular way to safely remain calm and focused, and get more refreshing sleep without worrying about next-day drowsiness. How does it work?

Our mental state is reflected in part by different brain waves. As the body absorbs Suntheanine, it passes through the blood-brain barrier which enables it to safely stimulate the production of alpha brain waves, a state often achieved by meditation. Instead of feeling frazzled, you might feel deeply relaxed and more mentally alert. This increase in alpha brain waves can also improve focus and learning ability.

At the same time, Suntheanine is reducing beta brain waves, which are associated with stress, an inability to concentrate, and difficulty falling asleep and staying asleep. Suntheanine can also increase the production of neurotransmitters dopamine and serotonin, which are associated with stress reduction, restful sleep, concentration and improved mood. The effects of Suntheanine can be felt between 20-30 minutes after ingestion and can last up to 8-12 hours. 

You can dial down your tension, get more much-needed rest and feel focused on the tasks you need to accomplish. Start by taking a dosage of 50 to 200 mg. of Suntheanine. If you’re really stressed, consume a minimum of 100 mg. for best results.

    Suntheanine is Taiyo’s pure form of L-theanine, produced via a patented fermentation process that mimics the natural process in green tea leaves. It promotes relaxation without causing drowsiness, positive mood, mental clarity, focus, reduces nervous tension, and helps prevent the negative side-effects of caffeine.
