Green tea has a long history of use in countries such as China and India as a medicinal beverage. Applied Nutrition Green Tea Fat Burner contains the effective thermogenic green tea extract, in combination with caffeine, chromium and a host of other ingredients designed boost energy and antioxidants. Known for its thermogenic properties, evidence suggests that green tea, particularly the well-studied epigallocatechin gallate, or EGCG, may speed up metabolism and prompt weight loss, reports the University of Maryland Medical Center.
Ingredients
Applied Nutrition Green Tea Fat Burner contains caffeine, green tea and chromium, which producers claim will help you increase your energy expenditure and weight loss. Green Tea Fat Burner also contains "Antioxidant Boost," comprised of a number of berries aimed at increasing antioxidants. Additionally, this supplement contains chromium, a naturally occurring mineral marketed as a weight-loss aid. Finally, this supplement includes the ingredient "Vitality Boost," which refers to a combination of yerba mate, a known stimulant, as well as other roots and herbs.
Green Tea
Thermogenesis refers to an increase in energy expenditure above your body's natural metabolic rate. Some of green tea's thermogenic effect is due to its caffeine content; however, green tea extract's ability to stimulate brown adipose tissue thermogenesis is greater than is attributable to its caffeine content alone, reported the "International Journal of Obesity" in February 2000. Additionally, green tea may also support weight management after weight loss, reported the "British Journal of Nutrition" in 2004.
Caffeine and Chromium
The "American Journal of Clinical Nutrition" in May 1990 reported that caffeine has a positive impact on metabolism and even in moderate doses has significant impacts on thermogenesis. Weight-loss supplements include chromium due to claims this mineral increases the effectiveness of insulin and promotes weight loss. According to an article published on the Vanderbilt University website, science has not supported the use of chromium as a weight loss aid.
Cautions
Each of the ingredients in Green Tea Fat Burner carries potential risks and side effects. Green tea extract and caffeine are generally safe for adult consumption and have minimal side effects. However, according to the National Center for Complementary and Alternative Medicine, there have been rare reports of liver problems for those using concentrated green tea extracts. High amounts of caffeine can cause side effects such as excessive heart and increased urination. Check with your doctor regarding potential drug interactions of green tea extract, as well as the other ingredients listed, prior to using Green Tea Fat Burner.
