The Active Ingredient Is: EGCG (Epigallocatechin Gallate)

EGCG is a potent polyphenol found in green tea that contributes to the antioxidant activity of green tea extracts.

This formula centres on decaffeinated green tea extract, with EGCG provided in a form that supports high bioactivity while keeping caffeine exposure low.

What Does EGCG Do?

EGCG helps support metabolic function and cardiovascular health, and may contribute to cellular protection in daily living, in line with EFSA and NHS-aligned guidance.

Scientific research suggests that green tea extracts containing EGCG can be associated with fat oxidation and body weight changes over time, while supporting broader antioxidant activity.
