The Active Ingredient Is: Green Tea Extract (Camellia sinensis)

Green Tea Extract describes concentrated compounds from Camellia sinensis leaf, mainly used as a plant-based supplement ingredient. This form is produced as a standardised extract taken from young, unfermented leaves to preserve antioxidant content.

This formulation is standardised to deliver consistent levels of active compounds, with the extract coming from whole green tea leaves picked at an optimal stage to maximise catechin content.

What Does Green Tea Extract Do?

Green Tea Extract provides catechins that contribute to antioxidant activity, supporting normal cellular protection. The extract also contains naturally occurring caffeine and may include L-theanine, which together form part of the product's composition.

In line with EFSA‑aligned understanding of nutrients, these components play a role in the body’s normal functions related to antioxidant activity and energy-related processes as part of a balanced diet.
