  Description:

  Epigallocatechin gallate (EGCG), also known as epigallocatechin 3gallate, 

  is the ester of epigallocatechin and gallic acid, and is a type of catechin.

  EGCG is the most abundant catechin in tea and is a potent antioxidant that 

  may have therapeutic applications in the treatment of many disorders 

  (e.g. cancer).

   It is found in green tea but not black tea; during black tea production, 

  the catechins are converted to theaflavins and thearubigins. In a high 

  temperature environment, an epimerization change is more likely to occur;

   however as exposure to boiling water for 30 straight minutes only leads to 

  a 12.4% reduction in the total amount of EGCG, the amount lost in a brief 

  exposure is insignificant. In fact, even when special conditions were used 

  to create temperatures well above that of boiling water, the amount lost 

  scaled up only slightly.

  Main Function

  1.Anti-atherogenic / Lowering cholesterol & triglycerides

  2.Enhancing metabolism and fat oxidation

  3.Reducing blood clotting

  4.Enhancing immune function

  5.Enhancing weight loss

  6.Anti-cancer
