Health Benefits of Green Tea and Green Tea Extracts

Green tea, and more recently green tea extracts, have been used for centuries as not only a beverage, but as a medicine as well. Practitioners of natural healing and medicines have long expressed a belief in several health benefits of green tea. Green Tea Extract [Immune System, Circulatory System] contains catechins, a type of polyphenol with powerful antioxidants that neutralize free radicals. Green tea also provides antimicrobial immune system support, helps support the vascular blood clotting function and helps maintain cholesterol levels already within the normal range. It also appears to support healthy kidney function.
A study published in the December 1999 issue of the American Journal of Clinical Nutrition and Urology show that substances which are abundant in green tea extracts may promote weight loss through thermogenesis (the body's rate of burning calories). Green tea seems to help in raising the metabolic rate and burning fat. In this study, subjects taking a green tea extract burned more fat calories than those in a control group. Another interesting point is that the affect was accomplished without the increase in heart rate experienced with more common diet pills and weight loss supplements which often have a stimulant base.
One obesity study indicates that long-term tea drinkers (those who drink tea over a period of years) appear to have lower body fat percentages.
Therefore, if you are unsure of the affect of your green tea brand, you might consider green tea extracts as an altenative or supplement. A recent analysis of green tea brands found however, that antioxidant levels of common teas have a great deal of variance. This was reported in an article from the American Association for the Advancment of Science: "Green tea shows antioxidant benefits in human plasma". Catechins, found in green tea, apparently increase the antioxidant capacity of human plasma, which could help reduce cardiovascular disease risk.
A recent Penn State study supports the view that the flavonoids in tea can reduce the risks for cardiovascular disease. Just to make the news better, the study also found that chocolate had similar health benefits as well. Green tea and green tea extracts have high antioxidant properties.
In addition to the normally brewed tea which is available in almost any neighborhood grocery store, green tea extract is a handy option for those who like to supplement their nutritional intake without having to find a place and time to actually brew a pot or cup of green tea.
Studies have indicated that green tea and green tea extracts can help lower cholesterol levels.



I drink black tea but admit I have not tried green tea before so I may try it. I also currently take a rosehip extract supplement which is also high in antioxidants and good for maintaining health.
