The green tea extract is a herbal derivate from the leaves and leaf buds of Camellia sinensis, the plant from which green, black, white, pu-erh and oolong tea varieties are made. It has been associated with various health benefits, many already proven by scientific research.
Depending on the production process, there are three types of extracts: strong infusions, soft, dry and partly purified extracts; the last being the most complex.
The extract is always standardized during the production process to make sure that the required percentage of the active ingredients is present in the final product. These active ingredients that give the tea its beneficial characteristics are polyphenols in the form of catechins, flavonoids and epigallocatechin gallate or EGCG. These are antioxidants that increase the metabolism, reduce the risk of heart diseases and have many other health benefits.
Green tea extract supplements are available over the counter either as capsules, pills or powder. For example, one capsule of standardized extract that is 90% polyphenols equals five cups of tea. There is extract standardized for 80% and as little as 15 % polyphenols, the latter being the least expensive type. No matter the percentage, tea extracts are better taken between meals to avoid decreased iron absorption.
Used for hundreds of years in Asia and known for its medical properties, green tea has recently been the subject of many studies that were conducted to prove the actual benefits of this type of tea on human health.
Promising results have been obtained proving the positive effect of green tea on colon, lung, liver and breast cancer. Three out of four patients with chronic lymphocytic leukemia from a small study of the Mayo Clinic showed significant regression of the disease after taking green tea extract for two months.
The extract has also proven beneficial for cardiovascular circulation, by reducing “bad cholesterol”. It suppresses the appetite and improves the oxidation of fat.
This is also the reason why green tea supplements are a popular weight loss solution for people of all ages. 100% natural, they have little to no side-effects. The catechins and caffeine in green tea act as fat burners, prevent the development of fat cells, reduce the absorption of fat and increase the process of burning gat for energy production. As you can see green tea acts on many levels when it comes to losing weight and this is why it has become so popular.
Some additional benefits of green tea extracts is they improve the immune system helping the body better fight infections, they are good for rheumatoid arthritis, it reduces the risk of heart attacks by reducing the risk of thrombosis, it helps in Alzheimer and Parkinson’s disease and may prevent tooth decay by killing the bacteria causing dental plaque.
All these reasons are more than enough to convince you to include extract supplements in your life.
When you decide to purchase a supplement look for one that is standardized to a minimum of 90% polyphenols and 55% EGCG. You should know that these products contain natural caffeine, but this type of caffeine has less side-effects than the caffeine in coffee. There are products that undergo a process of removing the caffeine content, but you should be advised that this may also diminish the characteristics of the active ingredients.
The quality of the extract may vary between the different brands on the market, so you’d better read the label before making the purchase to make sure the recommended dosage is not exceeded.
If you plan on improving your health, you should take advantage of the many benefits green tea has to offer and start using green tea extract products on a daily basis. You’ll soon notice improvements on many, many levels.
