Green Tea Extract is used in the CORE™ formula, the foundation of the entire CardioTrim health supplement line.

Green Tea extracts are powerful antioxidants that promote cardiovascular health and increase metabolic energy. For centuries, people around the world have considered green tea a general health tonic and associated its consumption with increasing longevity and improving the quality of life. Today, a significant body of scientific research supports the healthful benefits of green tea consumption as well green tea extract supplementation. The principle constituents in green tea responsible for its healthful benefits are a class of polyphenolic compounds called “catechins.” The predominant and most active of these energy contributing catechin is epigallocatechin gallat (EGCG). University of Switzerland in Geneva recruited 10 healthy young men and had them eat their normal diets. On three occasions, the researchers measured the participants' resting energy expenditure after giving them either a concentrated green tea extract (roughly equal to four gallons of brewed tea), 50 milligrams of caffeine or a placebo three times per day. While neither the caffeine nor the placebo affected metabolism, the green tea increased energy expenditure by 4 percent--equivalent to burning 80 extra calories. What's more, unlike caffeine, the green tea didn't increase the participants' heart rates. Although, the mechanisms behind its action remain unclear. The investigators note that green tea extract contains a high amount of EGCG. This compound may work with other chemicals to increase levels of fat oxidation and thermogenesis, where the body burns fuel such as fat to create heat.
