EGCG (Epigallocatechin Gallate) is a powerful catechin and antioxidant predominantly found in green tea. It’s one of the most studied polyphenols for its health-promoting effects. In sports nutrition, EGCG is valued for its potential to enhance fat oxidation, improve endurance, and provide cellular protection.
Its mechanisms include modulating metabolic pathways, increasing thermogenesis, and reducing oxidative stress. EGCG is often used in fat-burning or energy-boosting formulas, especially when paired with caffeine.
Additionally, it has been researched for its cardiovascular, anti-inflammatory, and neuroprotective properties, which contribute to overall health maintenance for active individuals.
