The Active Ingredient Is: EGCG (Epigallocatechin Gallate)

EGCG is a potent antioxidant polyphenol found in green tea that helps with cellular protection and overall metabolic health support. This compound is mainly derived from Camellia sinensis and is the key active constituent in green tea extract.

This formula provides EGCG from green tea extract standardised to a high percentage of the compound, with the extract designed to maximise EGCG content while staying vegan and caffeine-free.

What Does EGCG Do?

EGCG contributes to antioxidant activity by neutralising free radicals and supports metabolic health through mechanisms that may boost thermogenesis and fat oxidation, in line with evidence on polyphenols from green tea extracts.

These effects align with regulatory discussions on nutrient function and cellular protection, highlighting normal physiological roles in keeping oxidative balance and energy metabolism.
