More focus and relaxation with the amino acid from green tea
L-theanine is a natural amino acid from green tea, known for its calming yet concentration-enhancing effect.
This amino acid, which occurs in the tea leaves at a concentration of approx. 2 – 5%, is one of the reasons for the positive properties of green tea.
Through its effect on neurotransmitters such as GABA, serotonin and dopamine, this amino acid supports a balanced mental state. Studies show that it may help improve cognitive abilities, attention and emotional balance. It may increase alpha wave activity in the brain and thereby support a state of "relaxed concentration".
Our Edubily L-theanine contains the highly concentrated branded raw ingredient NeuroTeyanin® with 50 mg of pure L-theanine per capsule.
