The Active Ingredient Is: L-Theanine

L-Theanine is an amino acid known for its role in supporting relaxation and mood regulation. This form is AlphaWave L-Theanine, supplied from tea, and is used to provide a calming effect without sedation.

This ingredient is typically provided as a branded amino acid form derived from tea sources to support its natural physiological role.

What Does L-Theanine Do?

L-Theanine helps support brain activity associated with calmness and balanced mood, and it can influence neurotransmitter regulation to promote a relaxed mental state. It may also influence alpha-brain wave activity and reduce excitatory signaling in the brain, aligning with approved functional claims for normal brain function.

EFSA and NHS context emphasise normal physiological roles for these processes, with the mechanism involving balanced neurotransmitter action and brain activity that supports everyday wellbeing.
