Theanine: A Calming Amino Acid for Relaxation, Focus, and Sleep
Thorne’s Theanine provides a pure, potent dose of Suntheanine®, a patented and extensively researched form of the amino acid L-theanine. Found naturally in green tea, L-theanine is renowned for its unique ability to promote a state of “alert relaxation” without causing drowsiness. This makes it an exceptional supplement for individuals seeking to manage daily stress, enhance mental focus, and improve sleep quality. It is a foundational tool for navigating a demanding lifestyle with a calm and clear mind.
How It Works: The Science of Suntheanine® and Brain Waves
L-theanine exerts its benefits by directly influencing brain chemistry, promoting a more balanced and relaxed neurological state.
Promoting Alpha Brain Waves for Calm Focus
One of the most notable effects of Suntheanine® is its ability to increase the production of alpha brain waves. This brain wave pattern is associated with a state of wakeful relaxation—the calm, focused mindset you might experience during meditation or creative flow. Unlike sedatives, which can cause grogginess, L-theanine helps quiet “mental chatter” and allows you to concentrate more effectively, making it ideal for work, study, or any task requiring sustained attention.
Balancing Neurotransmitters for Mood and Sleep
L-theanine also helps to modulate key neurotransmitters that regulate mood and stress. It can increase levels of calming neurotransmitters like GABA, serotonin, and dopamine, while simultaneously helping to balance the effects of excitatory chemicals. This dual action helps to buffer the body’s stress response during the day. When taken before bed, this same calming mechanism helps quiet the mind, making it easier to fall asleep and achieve a more restful, restorative night’s sleep.
