Green tea extract is rich in polyphenolic compounds, predominantly catechins. Green tea extract is a natural alternative to chemical antioxidants. Green tea extract helps delay lipid oxidation in food.
Current methods for evaluating green tea extract in food are discussed. Keywords Green tea extract Antioxidant Catechins Flavour constituents Lipid oxidation Food application.
This cell damage is associated with aging and several diseases 2. Among the catechins in green tea, epigallocatechin gallate EGCG is the most researched and thought to provide the most health benefits. This, in turn, may prevent associated health concerns 3 , 4 , 5.
For example, in one study, 35 people with obesity took milligrams mg of green tea extract for 8 weeks. Their blood antioxidant capacity increased from 1. It should be noted that the participants in this small study were taking green tea extract in an amount considered to be in the toxic range.
Green tea extract is rich in antioxidants called catechins, which have been shown to increase antioxidant capacity and protect against oxidative stress. Oxidative stress increases fat buildup in your blood, which promotes inflammation in your arteries and leads to high blood pressure 6 , 7.
The antioxidants in green tea extract can decrease inflammation and help reduce blood pressure. They can also inhibit fat absorption in cells, helping reduce blood fat levels 8 , 9 , 10 , In one study, 56 people with obesity and high blood pressure took mg of green tea extract daily for 3 months.
They showed a significant decrease in blood pressure, compared with the placebo group 8. Additionally, they experienced significant reductions in blood fat levels, including lower triglycerides and both total and LDL bad cholesterol 8.
An older study involving 33 people between ages 21 and 71 years old with no lipid imbalances found that taking mg of green tea extract daily for 8 weeks reduced total cholesterol by 3.
Given that high blood pressure and high blood fat levels are risk factors of heart disease, regulating them can help promote heart health. The catechins in green tea may help reduce blood pressure and improve blood fat levels, which promotes heart health.
The antioxidants in green tea extract, especially EGCG, have been shown to protect brain cells from oxidative stress Green tea extract can also decrease the action of heavy metals like iron and copper, both of which can damage brain cells 15 , In a study, 12 people drank a soft drink containing either Then, while the participants worked on memory tests, brain images were obtained to assess brain function.
The green tea extract group showed an increase in brain function and improved task performance, compared with the placebo group Green tea extract has been shown to have a positive effect on brain health and memory, and it may help protect against brain diseases.
Green tea extract is rich in catechins, and it contains a decent amount of caffeine. Both catechins and caffeine have been shown to assist in weight loss by regulating the hormones that can enhance thermogenesis 19 , 22 , Thermogenesis is the process by which your body burns calories to digest food and produce heat.
Green tea has been shown to boost this process by making your body more effective at burning calories, which can lead to weight loss 23 , 24 , In one older study, 14 people took a capsule containing a mixture of caffeine, EGCG from green tea, and guarana extract before each meal.
It then examined the effect on calorie burning and found that the participants burned more calories, on average, in the following 24 hours In another well-designed study, 60 Caucasian adults took mg of green tea extract along with between and mg of caffeine or a placebo daily for 12 weeks.
This study found no significant effect on resting energy expenditure or body composition And since caffeine is known to stimulate energy expenditure, the modest weight loss effects of green tea extract may be due — at least in part — to the caffeine itself Those who regularly consume high amounts of caffeine greater than mg per day, or about 3 cups of coffee may not experience as great an effect from green tea extract In one week study, women with central obesity higher concentration of fat in the abdominal area took Those taking the green tea extract experienced significant weight loss, along with decreases in BMI, waist circumference, and cholesterol levels, compared with participants who were given a placebo It should be noted that the dosage of green tea extract used in this study is in the toxic range for daily catechin intake.
People taking high doses of green tea catechins should monitor their liver enzymes to avoid liver damage or acute liver failure 29 , While a cup of green tea contains 50— mg green tea catechins and 30—40 mg of caffeine, studies of green tea extract often contain mg or more of green tea catechins and up to mg of caffeine.
Those with sensitivity to caffeine or cardiovascular issues should consider this before taking green tea extract for weight loss.
Green tea extract may aid weight loss by increasing the number of calories your body burns through a process called thermogenesis. High doses of green tea extract are toxic and may lead to serious liver damage.
The catechins in green tea extract may also help reduce inflammation caused by some liver diseases, such as nonalcoholic fatty liver disease NAFLD 31 , One study gave 80 participants ages 20—50 years with NAFLD either mg of green tea extract or a placebo daily for 90 days The group who received green tea extract showed significant reductions in liver enzyme levels, which is an indication of improved liver health Similarly, 17 patients with NAFLD took mL of green tea, which contained at least 1 gram of catechins, daily for 12 weeks.
They had significant decreases in liver fat content, inflammation, and oxidative stress Talk with a healthcare professional to determine the right dosage for you. Green tea extract seems to help improve liver function by decreasing inflammation and oxidative stress. Specialized cells known as stem cells produce new cells to replace those that die.
This process keeps cells active and healthy. When this balance is disrupted, cancer can occur. The antioxidants in green tea extract, especially EGCG, seem to have favorable effects on the balance of cell production and death 33 , 34 , 35 , One small older study explored the effects of taking mg of green tea catechins per day for a year on men at risk of developing prostate cancer.
Green tea extract has been shown to help maintain cell health. It may even help prevent some types of cancer, though more research is needed. Whether taken as a supplement or applied to the skin, green tea extract has been shown to improve skin health A large review demonstrated that when applied to the skin, green tea extract can help treat a variety of skin concerns, such as dermatitis, rosacea, and warts.
As a supplement, it has been shown to help with skin aging and acne 38 , 39 , For example, a small study showed that consuming 1, mg of green tea extract daily for 4 weeks resulted in significant reductions in red skin bumps caused by acne Moreover, both supplements and the topical application of green tea extract seem to help prevent skin conditions like loss of skin elasticity, inflammation, premature aging, and cancer caused by exposure to UV rays 39 , A study involving 10 people revealed that applying a cream containing green tea extract to the skin for 60 days resulted in improved skin elasticity Additionally, a study showed that applying green tea extract to the skin reduced skin damage caused by sun exposure Interestingly enough, adding green tea extract to cosmetic products has been shown to benefit the skin by providing a moisturizing effect Antioxidants, like green tea catechins, can reduce cellular damage and delay muscle fatigue 44 , Additionally, 16 sprinters who took green tea extract for 4 weeks demonstrated increased protection against oxidative stress produced by repeated sprint bouts One study found that 14 men who actively engaged in physical activity and consumed green tea extract for 4 weeks increased their running distance by Green tea extract increases antioxidant protection against oxidative damage caused by exercise.
This translates to better exercise performance and recovery. The catechins in green tea, especially EGCG, have been shown to enhance insulin sensitivity and regulate the production of blood sugar, both of which can lower blood sugar levels 49 , A study gave 14 people with no underlying health conditions a sugary substance and either 1.
The group that consumed green tea experienced better blood sugar tolerance after 30 minutes and continued to show better results compared with the placebo group Keep in mind that these studies 51 , 52 were very small and that the participants had no underlying health conditions.
Many people with diabetes, on the other hand, take medications that affect their liver, and many have NAFLD, so they would need to monitor their liver enzymes.
An analysis of 17 studies concluded that green tea extract is useful in decreasing fasting blood sugar levels. It can also help lower the hemoglobin A1C value, which is an indicator of blood sugar levels over the past 2—3 months Green tea extract has been shown to increase insulin sensitivity and blood sugar tolerance, all while decreasing hemoglobin A1C and blood sugar levels.
Green tea extract is available in liquid, powder, and capsule forms. A wide selection can be found on Amazon. The liquid extract can be diluted in water, while the powder can be mixed into smoothies.
However, it has a strong taste. The recommended dosage of green tea extract is between — mg per day.
Green tea contains antioxidants Iron alloy properties Green tea antioxidant properties been implicated Genetics and fat distribution contribute to reduced risk of cardiovascular disease. This may antipxidant explained antioxjdant part by the green tea's antioxidant properties. Green tea is a rich source of flavonoids with high antioxidant activity both in vitro and in vivo. This includes the ability of green tea to lower the oxidizability of low-density lipoprotein LDL in vitro. In vivo lipid oxidation as measure by plasma lipid peroxides and LDL oxidizability are significantly decreased by green tea.Green tea antioxidant properties -

However, it has a strong taste. The recommended dosage of green tea extract is between — mg per day. This amount can be obtained from 3—5 cups of green tea, or about 1. Some supplements contain only dry green tea leaves, while others contain isolated forms of one or more catechins.
Because supplements are not FDA regulated to ensure safety, purity, or verification of contents, you should only purchase supplements that have been analyzed by an independent lab to verify purity and content. Both exceeding the recommended dose and taking it on an empty stomach may cause serious liver damage 30 , Green tea extract can be consumed in capsule, liquid, or powder form.
The recommended dose is — mg, taken with food. Thanks to its high antioxidant content, green tea extract has been shown to help improve health and body composition.
