Catechins and Epigallocatechins
Catechins and Epigallocatechins are Flavonoid phytochemicals compounds found in green
tea which also contains Polyphenols. Together, Catechins and Polyphenols comprise the
active ingredients which have been found through numerous studies to possess strong
antioxidant and anticarcinogenic abilities.
IMMUPRO™ contains the highest grade of green tea extract
available on the market today with a guaranteed minimum 50% Epigallocatechins gallate.
