Green tea extract is produced from the leaves of Camellia sinensis, a plant that has been used medicinally for over 4,000 years. The extract contains high concentrations of polyphenols, specifically catechins such as epigallocatechin gallate (EGCG), which comprise 30-40% of the dry weight of green tea leaves. These catechins function as antioxidants and have been studied for their potential effects on metabolism, cardiovascular health, and exercise performance.
The manufacturing process involves either steam treatment (Japanese method) or pan-firing (Chinese method) of fresh tea leaves to prevent oxidation, followed by drying and mechanical processing into powder or liquid concentrate forms. This process concentrates the bioactive compounds while removing water content and some tannins that contribute to bitterness in brewed tea. A typical green tea extract supplement contains 50-90% polyphenols, compared to approximately 8-12% in brewed green tea.
Research indicates that green tea catechins may influence fat oxidation, thermogenesis, and exercise endurance through various mechanisms including inhibition of catechol-O-methyltransferase (COMT) enzyme and activation of AMP-activated protein kinase (AMPK) pathways. The standardized extract form allows for consistent dosing of these compounds, typically providing 200-400mg of EGCG per serving compared to 25-50mg found in a single cup of brewed green tea.
