L-Theanine is the predominant amino acid in tea (natural tea extract), which produces calming effects in the brain by increasing serotonin and dopamine levels and blocking the binding of L-glutamic acid to glutamate receptors. This can work as a natural stress relief.

L-Theanine supplements are a ‘’feel good’’ supplement that contributes to a feeling of well-being with no side effects or adverse reactions. It is a great way to improve mood naturally. In fact, in Japan L-Theanine is added to soft drinks and chewing gum in order to induce relaxation.

Calming effects of L-Theanine

L-Theanine´s calming, mood-enhancing effect is achieved by helping to increase alpha brain-waves, electrical brain activity that normally occurs when we are relaxed, thus helping to improve mood naturally.

Mood modulator

L-Theanine is a highly desirable mood modulator that contains no harmful or toxic substances. Instead, you are using a natural mood enhancer product which produces the effects otherwise obtained by meditation, massage or aromatherapy. L-Theanine brings about a sense of calm and well-being. This practical mood enhancer supplement in capsule form can improve mood naturally and induce feelings of relaxation without drowsiness.

A pure form of L-Theanine

Beware of L-Theanine imitations. This product contains Suntheanine®, a patented product and the only pure form of L-Theanine supplement protected by 40 American and international patents and scientifically proven in clinical studies to be safe and efficacious. Other products claiming to contain L-Theanine in fact only contain 50% L-Theanine, the other 50% being a different form of theanine known as “D-theanine” whose effects have yet to be demonstrated.

Would you like to try the most effective form of patented L-Theanine supplements to improve mood naturally? Simply place your order online and we will take care of the rest. Prompt delivery assured.
