Green Tea Extract
- Free-radical scavenging, powerful antioxidant polyphenols
- Supports a healthy immune system
- Helps to maintain healthy weight
Green tea extract is taken from Camellia sinesis, the green-tea bush; it is composed primarily of polyphenols, especially catechins such as EGCG; and has been shown to have a massive variety of health benefits. LiftMode Green Tea Extract is decaffeinated. Major benefits of green tea extract include: antioxidant effects, anti-inflammatory effects, antibiotic and antiviral effects, support of reduction in body fat, and promotion of good general health. Green Tea Extract has been researched in the lab as a potential potent cancer and heart disease fighting antibiotic and antiviral. The recommended dose for a strong green tea extract is around 250-500mg extract daily. Side effects of green tea extract may include headache. Very large single-serving amounts of Green Tea Polyphenols have been found to potentially stress the liver; however, recommended amounts taken in divided portions are much less likely to cause liver stress.
Green Tea extract reviews
“This product is strong, with a strong flavor. It takes getting used to, but once you figure it out, the benefit is that its very concentrated, and so the antioxidant properties may work faster. I feel the cleansing effects immediately, on my tongue and also in my stomach. This jar of tea will last long, because its huge. I suggest mixing two scoops with a whole lemon, a tablespoon of honey and about 4oz of warm water (dissolves better in warm water.)” – adekemi, LiftMode user review
“This product has too many benefits to list. I decided to try this product to supplement my weight loss regimen. I’d hit a block and was unable to shed additional pounds after a certain point. I’ve tried a variety of weight loss supplements and supplement combinations in the past but nothing has worked so well with very few if any side effects...” – Brad V, LiftMode user review

What is Green Tea Extract?
Green tea (Camellia sinensis) is a well-known and popular herbal tea originating in China and Asia. It has many potent antioxidant effects and the extract is becoming popular in herbal and alternative medicine. In fact, it may be one of the most beneficial herbal medicines known to man. A list of all the benefits of green tea would be very long and tiresome to the reader which is why we will expand only on the top few benefits of green tea extracts. The extract of green tea is composed primarily of three main chemical groups, namely: polyphenols, the specific class of polyphenols known as catechins, and the specific catechin known as EGCG. All of these have several major health benefits.
Green Tea extract benefits / dosage
One of the primary benefits of the polyphenols and catechins found in green tea is their ability to act as potent antioxidants.
In general, there are two primary benefits of antioxidants: removal of oxidized free radicals like superoxide, which are known to be carcinogenic and mutagenic; and the reduction of low-density lipoproteins (LDLs) which are associated with negative effects of high cholesterol and heart disease.
The best thing about green tea extract with regard to its antioxidant strength is that all three of the major constituents act to prevent LDL oxidation in different manners. Studies have shown the mechanisms by which polyphenols, catechins and especially EGCG target and prevent LDL oxidation and each one acts on a different stage of the process, thereby creating a triple defence against the negative effects of lipid oxidation in the blood.
Studied for potential prevention of cancer
A great deal of research with Green Tea polyphenols and Green Tea extracts have been carried out to determine if Green Tea extracts may have anti-cancer benefits. If proven, this benefit would be in part linked to the antioxidant effects of the major constituents of green tea extract. Many studies indicated the ability of green tea to prevent and disable the growth of cancerous cells and to eliminate dangerous carcinogenic free radicals from the body.
Apart from the potential indirect reduction of risk of cancer from antioxidant properties, green tea extract has also been shown to increase the efficiency of anticancer chemotherapy agents. One study found that using green tea in conjunction with a commonly used chemotherapy chemical heightened the concentration of the chemotherapy unit in cancerous cells, yet not in normal cells. It therefore enhanced the anticancer properties of a well-used chemotherapy treatment.
Examples of results of some of the large studies on anticancer effects of green tea use include a 48% reduction in the risk of prostate cancer formation in a study of over 49’000 men in Japan; and a 59% reduction in the risk of formation of colorectal cancer in a study on over 69’000 women in China.
Studied for potential prevention of heart disease
Flavonoids in green tea extract have been researched to determine if they may be beneficial in the prevention of coronary heart disease due to their antioxidant effects. One study showed that the polyphenols present in green tea were highly effective in the prevention of coronary heart disease and atherosclerosis. This would be especially useful in modern Western society with the high prevalence of obesity, excessive alcohol consumption and a high-sugar diet.
In several studies, polyphenols and catechins from green tea have been shown to reduce inflammatory effects of inflammatory agents and UV. Studies use specific chemicals known to produce symptoms of inflammation and then treat it with extracts from green tea and results show significant decreases in the inflammation symptoms. Green tea extracts have also been shown to be effective against immunosuppression caused by excessive UV exposure, and have also been shown to be effective against the action of cytokines that are induced by tumours.
Studied for antibiotic and antiviral effects
Catechins and polyphenols have been researched as potentially effective compounds against a number of bacterial and viral infections, and has especially shown promising antibiotic activity on the types of bacteria that infect the mouth and cause bad breath and tooth decay.
Studied for potential reduction in the risk of development of Type-II diabetes
Type-II diabetes is a major global problem due to high-sugar diets and low-exercise lifestyles. A major review on seven different studies, found that in over 280’000 people, those who drank green tea had an 18% reduction in the risk of type-II diabetes.
Reduction of body fat
Several studies have shown the efficiency of green tea extract in the reduction of the formation of body fat – specifically in the abdominal region.
EGCG (epigallocatechin-3-gallate) is one of the most important constituents of a green tea extract. It has been found to be highly effective in reducing growth of tumours and inducing apoptosis in cancer cell lines.
“Much of the cancer chemopreventive properties of green tea are mediated by EGCG that induces apoptosis and promotes cell growth arrest by altering the expression of cell cycle regulatory proteins, activating killer caspases, and suppressing oncogenic transcription factors and pluripotency maintain factors... Various clinical studies have revealed that treatment by EGCG inhibits tumor incidence and multiplicity in different organ sites such as liver, stomach, skin, lung, mammary gland and colon.” (Singh et al, 2011)
Green Tea extract recommended dosage
As with all extracts, recommended dosage is dependent on the strength and potency of the extract. For a relatively strong extract, the recommended dosage of green tea extract is around 250-500mg daily.
Green Tea extract side effects and warnings
Side effects of green tea extract are rare and dose dependant. Since the constituents of green tea have such potent effects in aiding health, high doses may produce some side effects. These may include headache, nervousness, sleep problems, nausea, irritability, heartburn, dizziness and confusion. However, most of these side effects pertain to caffeine containing Green Tea Extracts, whereas LiftMode’s Green Tea Extract is decaffeinated and contains only the beneficial polyphenols, reducing the chance of these side effects. Large single-serving amounts of Green Tea Polyphenols have occasionally been found to stress the liver; recommended amounts when taken in divided portions do not.
