The Active Ingredient Is: L-Theanine

L-Theanine is basically an amino acid that comes from green tea and helps with relaxing and supporting your brain power. This product offers L-Theanine in a vegetarian capsule for easy adding to daily routines.

This ingredient comes in a vegetarian/vegan capsule and is free from common allergens, which fits with typical supplement sourcing found in research summaries.

What Does L-Theanine Do?

L-Theanine helps with relaxation and may support a calm, alert mind by modulating neurotransmitters and promoting alpha brain wave activity, a mechanism described in evidence summaries looked at for EFSA-compatible functions.

These everyday biological functions help support daily calm and focus without making you sleepy, which aligns with UK and EU guidance on nutrient function claims.
