Epigallocatechin gallate (EGCG) is a catechin found in green tea.
Research has shown this catechin is the most potent with activities ranging from scavenging free radicals to burning fat. EGCG may help protect against a number of cancers by stopping the blood supply to tumors (angiogenesis) and causing cancer cells to self-destruct (apoptosis). It also encourages phase 2 detoxifying enzymes in the liver.
EGCG helps to inhibit the oxidation of LDL cholesterol, which is a key factor in the development of heart disease.
EGCG also may help to promote thermogenesis-or fat burning activity-by inhibiting the enzyme catechol-O-methyl-transferase which inactivates norepinephrine.
