Green Tea Leaf Extract
Green tea extract is obtained from green tea leaves. It contains antioxidant materials, primarily green tea catechins. Nowadays, it is becoming increasingly popular among people for the various health benefits it provides. Four different types of green tea extracts are soft extracts, dry extracts, partly purified extracts and strong infusions.
Origins of Green Tea Leaf Extract
Green tea has its origins coming from China and is now being consumed by people throughout Asia and the West. It comes from a plant named Carmellia sinensis. Green tea contains natural anti oxidants such as epigallocatechin gallate (EGCG).
Strong infusions extract is made by soaking tea leaves in aqueous solution of alcohol.
To obtain dry extracts, strong infusions are concentrated up to 40-50% solids. After getting sprayed they become dehydrated extract and powder.
For soft extracts, the solution processed by strong infusions is concentrated further to 20-25%.
For partly purified extracts, purification processes such as solvent extraction, chromatography or membrane extraction and separation techniques are used to obtain a higher content of tea catechins.

How it Helps in Weight Loss?
Along with other health benefits, green tea can also facilitate you with weight reduction*. Green tea helps the body burn fats and calories.
Green Tea Burns Fat
After its intake sugar and fats are synthesized in your body and are converted in to triglyceride. Triglyceride is vital since it provides energy to perform different functions of the body, but excess of triglyceride is converted into fats. This in turn can result in obesity.
Since green tea has high amount of polyphenols it can defy the risk of excess triglyceride. Polyphenol activates a certain enzyme, which dissolves the excess triglyceride. Hence, regular intake of green tea can reduce* the amount of body fat in your body.
Green Tea Stimulates Metabolism
The various antioxidants found in green tea can help you benefit in many ways. The epigallocatechin gallate, or EGCG, helps stimulate metabolism and makes weight loss* easier. Caffeine along with EGCG enables the central nervous system to release fat in to the blood stream and then the body can use the fat as fuel.
Green Tea Improves* Stamina
Since exercise is one of the most effective ways to lose* weight, green tea not only sheds calories, but it also improves* energy levels and helps a lot in muscle building, which again boosts* metabolism. Catechin polyphenols,present in green tea, stimulate the liver and muscle cells to use more fats. Hence carbohydrates will be used up at a lesser pace, which in turn enables the body to exercise for longer.
According to research, green tea can only boost* metabolism up to a certain extent (some say 4%, which equals to only 100 calories per day). If you have to burn calories and shed weight in a very short period of time, green tea might not be the best preference. However, along with helping you with maintaining a healthy weight, it can also help you live a healthier life.
