polyphenols, called catechins (sometimes referred to as tea flavonoids).
The family of catechins are; Gallocatechin (GC), Epigallocatechin

yet discovered. EGCG is 100 more powerful than vitamin C and 25 times

catechins. The most abundant catechins are especially found in green
tea. The leaf bud and first leaves of tea plant are richest in
epigallocatechin gallate, that’s green tea - the best source of EGCG.

EGCG and weight loss
studies suggest that EGCG may help with weight loss and fat burning by
stimulating and promoting thermogenesis, a process where your body
releases heat through a chemical reaction within your cells:
increasing metabolic rate
promoting fat oxidation
boosting energy levels
EGCG is beneficial as part of weight loss program.
