Tea contains Catechins, a type of Antioxidant. In a freshly picked tea leaf, catechins can comprise up to 30% of the dry weight. Catechins are highest in concentration in white and Green teas, while black tea has substantially fewer due to its oxidative preparation .Research by the U.S. Department of Agriculture has suggested the levels of antioxidants in green and black tea do not differ greatly, as green tea has an Oxygen Radical Absorbance Capacity (ORAC) of 1253 and black tea an ORAC of 1128 (measured in µmol TE/100 g).Antioxidant content, measured by the lag time for oxidation. About half(50%) of the catechin content of tea is EGCG Just a small quantity of tea leaves will steep many cups of tea.
It is this relative abundance that makes green tea special. No other food or everage contain this level of antioxidants.
EGCG is the focus of almost every scientific study.
It may have health benefits as a nutritional supplement for cancer, atherosclerosis, blood sugar control, HPV virus infection, and neurodegenerative diseases. You can obtain this substance through drinking green tea or an extract supplement. On average, a cup of green tea will have roughly 100 mg per 8 ounces. The amount of EGCG present in green tea varies with different brands of the product, the region it is grown, amount of brewing time, age of the leaves.
GrinRich offers a convenient way to get the benefits of green tea in a highly concentrated cap form. It is standardized for bioflavonoid-like antioxidants known as polyphenols, particularly EpigallocatechinGallate. EGCG has been found in scientific studies to be a potent antioxidant.
The health benefits of this amazing antioxidant are deep and wide ranging literally covers every part of the body.
Catechin, has been found to outperform Vitamin C and beta-carotene ten times in scavenging the alkyl peroxyl radical. One study found green tea polyphenols to be more potent antioxidants than Vitamin C, Vitamin E, rosemary extract, and even curcumin in some systems.
According to the U.S. National Cancer Institute, in laboratory studies catechins scavenged oxidants before cell damage occurred, reduced the number and size of tumors, and inhibited the growth of cancer cells.
Researchers found those who drank 5 or more cups of green tea a day were 16% more likely to live longer than those who drank less than one cup a day. Heavy green tea drinkers are also 26% less likely to die from heart disease.
Green Tea Extract
Green tea contains six types of catechins: EGCG, EGC, ECG, EC, GC and C.
EGCG is100 times more potent than vitamins C and 25 times more effective than vitamin E.
One cup of green tea provides 10-40 mg of polyphenols and has antioxidant catechins. EGCG as an antioxidant is about 25-effects greater than a serving of broccoli, spinach, carrots, or strawberries.
