National Public Radio reports that as of 2010, 72 million adults are considered obese within the United States and more than 60 percent of Americans are either overweight or obese. Being overweight and obese may not only be aesthetically unappealing to some, but carrying extra body fat leads to serious health consequences, some of which are life threatening. Because of this, many turn to natural supplements to assist in shedding pounds. Green tea pills are among the most popular of these supplements, and while a plethora of manufacturers release green tea products, not all are effective or safe.
Green Tea Active Compounds
Six polyphenols, which are known as catechins, compose green tea. These include gallaogatechin, epigallocatechin, epicatechin gallate, catechin, apigallocatechin gallate and epicatechin. Apigallocatechin gallate, also known as ECGC, is the most studied and potentially the most effective out of these compounds. The University of Maryland Medical Center reports these catechin compounds contain a higher concentration of antioxidants than vitamin C. Other active constituents within green tea include alkaloids, which are known to provide this herb with its stimulating effects.
