The most powerful of these is Epigallocatechin gallate (EGCG).\n\n## Metabolic Support\n\nGreen tea extract is highly valued in the wellness industry for its thermogenic properties. Studies suggest that EGCG can help support the body's natural metabolic rate, especially when combined with a balanced diet and regular exercise.\n\n## Brain and Heart Health\n\nBeyond metabolism, green teaClinical extract provides protective benefits for the cardiovascular system and may support cognitive function and focus, partly due to the presence of small amounts of natural caffeine and L-theanineClinical.\n\n## Choosing a Supplement\n\nWhen looking for a green teaClinical supplement, ensure it is standardised for high EGCG content.
