What is green tea extract?
Green tea extract is derived from the leaves Camellia sinensis , from which green, black and oolong tea are made. It is associated with several health benefits, many of which are supported by preliminary scientific research. This includes the potential properties of cancer fighting and a strong antioxidant effect that protects the body from the harmful effect of free radicals. However, the scientific community notes that continuing research is required.
Green tea has been used in India and China for healing purposes for almost 5,000 years. It is made slightly by steaming the leaves before allowing them to dry, helping to maintain the active properties of the plant. Oolong tea is produced by allowing the leaves to be slightly fermented before drying and black tea is made by allowing the leaves to ferment longer. Fermentation decomposes active ingredients, so green tea or its extract is tea choice.
Green tea extract as much as many herbs is standardized in the production phase to guarantee that a certain percentageThe active ingredients remain present in the final capsuled form. The active ingredients are polyphenols in the form of flavonoids catechins and epigallocatechin Gallate (EGCG) . Polyphenols, flavonoids, catechins and EGCG are strong antioxidants that seem to disrupt and reduce the spread of certain types of cancer cells. EGCG antioxidant activity in green tea extract is reportedly up to 100 times stronger than vitamin C or E.
between populations in China and Japan, where a large amount of green tea is consumed daily, the rate of cancer is statistically lower. Scientific research from renowned sources is now growing, which shows promising results about how the active ingredients in green tea can be responsible for reducing the degree of different Kinds cancer.
jonsson comprehensive Cancer Center, award -winning Research Center for Cancer, presented in their discoveries CancerIn 2005, the newsletter, which has indicated several published studies that the extract of green tea "induces death in cancer cells" without influencing healthy cells, and takes cancer cells in the production of "independent blood" to spread to other parts of the body. This shows that the extract can help maintain the cancer contained, which makes treatment easier.
Studies conducted by other respected universities and clinics have also shown promising results, which include, inter alia, breast, liver, lung and colon cancer. The Mayo Clinic conducted a small study using four patients with chronic lymphocytic leukemia (CLL). Three out of four patients showed significant CLL regression after collection of green tea extract for several months. The prognosis of the fourth patient was improved, but not significantly. Great attempt is needed to see if these results can be repeated with consistency.
green tea extract can also be beneficial in improving cardiovascularCirculation by lowering LDL or "bad cholesterol", suppressing appetite and improving fat oxidation. However, these claims do not accept the scientific community because they are based on animal models and only a few studies of man.
When buying this extract, shoppers should look for a product that is standardized to at least 90% of polyphenol and 55% EGCG. Using this standard, 500 milligrams (mg) will contain 275 mg EGCG (500 mg x 55% = 275 mg). According to some sources, the proposed daily dose is approximately 2 cups (473 ml) of green tea per day or equivalent to 200 to 400 mg EGCG per day. Note that green tea contains natural caffeine. Processes that remove caffeine can also reduce the active ingredients.
The quality of green tea extract will vary with interdrishers, so consumers should carefully read the labels and do not exceed the recommended dosage. This supplement should not be used instead of professional medical care and is not recommended for pregnant women notyou nursing women. People should regularly visit a healthcare professional and keep a healthy routine of diet and exercise for optimal health.
