    Suntheanine® is a purified, clinically researched, and patented form of L-theanine supported by more than 50 studies demonstrating its safety and efficacy. It safely relaxes but won’t cause drowsiness.

    The main benefits of L-theanine are associated with promoting a relaxed state without causing drowsiness. L-theanine may also have mild cognitive-enhancing effects, especially when taken with caffeine. L-theanine has also been shown to suppress the blood pressure increasing effects of caffeine and may also counteract blood pressure increases under stressful conditions. Though it does not provide any sedative-like effects, L-theanine enhances sleep quality by promoting a more relaxed state in the brain.

    After consumption, L-theanine can cross the blood-brain barrier and affect brain activity by promoting increased alpha-waves, a pattern of brain activity associated with a more relaxed state. The tendency of L-theanine to increase alpha waves may explain its stress and anxiety reducing effects.

    L-theanine may be beneficial for those who experience increased blood pressure in stressful situations. One study found that people who usually experienced higher blood pressure after specific mental tasks found that L-theanine helped reduce an increase in blood pressure.

    A growing body of research suggests that L-theanine helps promote healthy mood. A 2017 study published in the journal Acta Neuropsychiatrica on people with major depressive disorder found that L-theanine improves symptoms of depression among other benefits.
