ABOUT THE AUTHOR. David Common. 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. 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.

Many studies have shown that green tea extract can promote weight loss, blood sugar regulation, disease prevention, and exercise recovery. It can also help keep your skin and liver healthy, reduce blood fat levels, regulate blood pressure, and improve brain health.

It can be consumed in capsule, liquid, or powder form. Amounts above this may be toxic. Plus, people with diabetes or those taking certain medications should speak with a healthcare professional before taking any amount of green tea extract.

Whether you want to improve your general health or decrease your risk of disease, green tea extract is an easy way to add health-boosting antioxidants to your diet. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

VIEW ALL HISTORY. EGCG is a plant compound particularly prominent in green tea that's linked to several benefits. This article reviews EGCG, including its health…. However, studies in people have produced conflicting findings.

For example, one large-scale population-based study found that green tea offered protection against the development of esophageal cancer, particularly among women. Another population-based study found just the opposite, green tea consumption was associated with an increased risk of esophageal cancer.

In fact, the stronger and hotter the tea, the greater the risk. Given these conflicting results, more research is needed before scientists can recommend green tea for the prevention of esophageal cancer. Lung cancer. While green tea polyphenols have been shown to inhibit the growth of human lung cancer cells in test tubes, few clinical studies have looked at the link between drinking green tea and lung cancer in people, and the studies that have been done show conflicting results.

One population-based study found that Okinawan tea, similar to green tea but partially fermented, was associated with lower lung cancer risk, particularly among women.

But a second study found that green tea and black tea increased the risk of lung cancer. More studies are needed before researchers can draw any conclusions about green tea and lung cancer.

Green tea should not be used by patients on bortezomib therapy. Pancreatic cancer. In one large-scale clinical study researchers compared green tea drinkers with nondrinkers and found that those who drank the most tea were less likely to develop pancreatic cancer.

This was particularly true for women, those who drank the most green tea were half as likely to develop pancreatic cancer as those who drank less tea. However, it is not clear from this population-based study whether green tea is solely responsible for lowering pancreatic cancer risk.

More studies are needed before researchers can recommend green tea for the prevention of pancreatic cancer. Prostate cancer. Laboratory studies have found that green tea extracts prevent the growth of prostate cancer cells in test tubes.

A large clinical study in Southeast China found that the risk of prostate cancer went down with increasing frequency, duration, and quantity of green tea consumption. However, both green and black tea extracts also stimulated genes that cause cells to be less sensitive to chemotherapy drugs.

People who are undergoing chemotherapy should ask their doctors before drinking green or black tea, or taking tea supplements. Skin cancer. The main polyphenol in green tea is epigallocatechin gallate EGCG. Scientific studies suggest that EGCG and green tea polyphenols have anti-inflammatory and anticancer properties that may help prevent the development and growth of skin tumors.

Stomach cancer. Laboratory studies have found that green tea polyphenols inhibit the growth of stomach cancer cells in test tubes, however, studies in people have been less conclusive.

In two studies that compared green tea drinkers with nondrinkers, researchers found that people who drank tea were about half as likely to develop stomach cancer and stomach inflammation as those who did not drink green tea.

However, a clinical study with more than 26, men and women in Japan found no association between green tea and stomach cancer risk. Some studies even suggest that green tea may increase the risk of stomach cancer.

Green tea may help reduce inflammation associated with Crohn disease and ulcerative colitis, the two types of IBD. If green tea proves to help prevent colon cancer, it would also help those with IBD because they are at higher risk for colon cancer.

Green tea has been used traditionally to control blood sugar levels. Animal studies suggest that green tea may help prevent the development of type 1 diabetes and slow the progression once it has developed.

In people with type 1 diabetes, their bodies make little or no insulin, which helps convert glucose or sugar into energy. Green tea may help regulate glucose in the body. Research also suggests that regular consumption of green tea may help manage type 2 diabetes.

Population-based studies have shown that men who drink more than 10 cups of green tea per day are less likely to develop liver problems.

Green tea also seems to protect the liver from the damaging effects of toxic substances such as alcohol.

Animal studies have shown that green tea helps protect against liver tumors in mice. Results from several animal and human studies suggest that plant chemicals in green tea called catechins, may help treat viral hepatitis, an inflammation of the liver.

In these studies, catechin was used by itself in very high amounts. It is not clear whether green tea, which has a lower concentration of catechins, would have the same benefits. It is important to note that 10 cups of green tea a day could cause problems due to high levels of caffeine.

Ask your doctor about the best way to include green tea in your treatment. Clinical studies suggest that green tea extract may boost metabolism and help burn fat. One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese.

However, other studies show no benefit. Preliminary studies suggest that drinking green tea can help prevent dental cavities. More research is needed.

Green tea may also be useful in inflammatory diseases, such as arthritis. Research suggests that green tea may help arthritis by reducing inflammation and slowing the breakdown of cartilage.

Chemicals in green tea may help treat genital warts, treat dermatologic conditions, and prevent symptoms of colds and flu.

Green tea may play a role in preventing Parkinson disease, cognitive decline, and osteoporosis. Studies also show that drinking green tea is associated with reduced risk of dying from any cause. Green, black, and oolong tea are all derived from the leaves of the Camellia sinensis plant.

Originally cultivated in East Asia, this plant grows as large as a shrub or tree. Today, Camellia sinensis grows throughout Asia and parts of the Middle East and Africa. People in Asian countries more commonly consume green and oolong tea while black tea is most popular in the United States. Green tea is prepared from unfermented leaves, the leaves of oolong tea are partially fermented, and black tea is fully fermented.

The more the leaves are fermented, the lower the polyphenol content and the higher the caffeine content. Green tea has the highest polyphenol content while black tea has roughly 2 to 3 times the caffeine content of green tea.

Researchers think the health properties of green tea are mostly due to polyphenols, chemicals with potent antioxidant potential. In fact, the antioxidant effects of polyphenols seem to be greater than vitamin C.

The polyphenols in green tea also give it a somewhat bitter flavor. Polyphenols contained in teas are classified as catechins.

Green tea contains six primary catechin compounds: catechin, gallaogatechin, epicatechin, epigallocatechin, epicatechin gallate, and apigallocatechin gallate also known as EGCG.

EGCG is the most studied polyphenol component in green tea and the most active. Green tea also contains alkaloids including caffeine, theobromine, and theophylline.

They provide green tea's stimulant effects. L-theanine, an amino acid compound found in green tea, has been studied for its calming effects on the nervous system. Most green tea dietary supplements are sold as dried leaf tea in capsule form.

Look for standardized extracts of green tea. There are also liquid extracts made from the leaves and leaf buds. The average cup of green tea contains 50 to mg polyphenols antioxidants.

Decaffeinated green tea products contain concentrated polyphenols. Caffeine-free supplements are available. Depending on the brand, 2 to 3 cups of green tea per day for a total of to mg polyphenols or to mg per day of standardized green tea extract is recommended.

Caffeine-free products are available and recommended. The use of herbs is a time-honored approach to strengthening the body and treating disease.

However, herbs contain active substances that can trigger side effects and interact with other herbs, supplements, or medications. For these reasons, people should take herbs with care, under the supervision of a practitioner knowledgeable in the field of botanical medicine.

People with heart problems or high blood pressure, kidney problems, liver problems, stomach ulcers, and psychological disorders, particularly anxiety, should not take green tea. Pregnant and breastfeeding women should also avoid green tea.

People with anemia, diabetes, glaucoma, or osteoporosis should ask their health care provider before drinking green tea or taking an extract.

People who drink large amounts of caffeine, including caffeine from green tea, for long periods of time may experience irritability, insomnia, heart palpitations, and dizziness. Caffeine overdose can cause nausea, vomiting, diarrhea, headaches, and loss of appetite.

If you are drinking a lot of tea and start to vomit or have abdominal spasms, you may have caffeine poisoning. If your symptoms are severe, lower your caffeine intake and see your health care provider.

If you are being treated with any of the following medications, you should not drink green tea or take green tea extract without first talking to your health care provider:.

Green tea may inhibit the actions of adenosine, a medication given in the hospital for an irregular and usually unstable heart rhythm. Green tea may increase the effectiveness of beta-lactam antibiotics by making bacteria less resistant to treatment. Caffeine, including caffeine from green tea, may reduce the sedative effects of these medications commonly used to treat anxiety, such as diazepam Valium and lorazepam Ativan.

Beta-blockers, Propranolol, and Metoprolol. Caffeine, including caffeine from green tea, may increase blood pressure in people taking propranolol Inderal and metoprolol Lopressor, Toprol XL. These medications are used to treat high blood pressure and heart disease.

Blood-Thinning Medications. People who take warfarin Coudamin should not drink green tea. Since green tea contains vitamin K, it can make this medication ineffective. Other compounds in green tea may slow blood clotting and therefore increase the blood-thinning effect of these medications.

You should not mix green tea and aspirin because they both prevent blood from clotting. Using the two together may increase your risk of bleeding. If you are taking medications that promote blood thinning, discuss green tea consumption with your physician.

The combination of green tea and chemotherapy medications, specifically doxorubicin and tamoxifen, increased the effectiveness of these medications in laboratory tests.

However, the same results have not been found in studies on people. On the other hand, there have been reports of both green and black tea extracts affecting a gene in prostate cancer cells that may make them less sensitive to chemotherapy drugs. For that reason, people should talk to their doctors before drinking black and green tea or taking tea extracts while undergoing chemotherapy.

Clozapine Clozaril. The effects of the clozapine may be reduced if taken within 40 minutes after drinking green tea. When taken with ephedrine, green tea may cause agitation, tremors, insomnia, and weight loss.

Green tea has been shown to reduce blood levels of lithium, a medication used to treat bipolar disorder. That can make lithium less effective. Monoamine Oxidase Inhibitors MAOIs. Green tea may cause a severe increase in blood pressure, called a "hypertensive crisis," when taken together with these drugs used to treat depression.

Examples of MAOIs include:. Birth control pills. Oral contraceptives can prolong the amount of time caffeine stays in the body, which may increase its stimulating effects. A combination of caffeine, including caffeine from green tea, and phenylpropanolamine, used in many over-the-counter and prescription cough and cold medications and weight loss products, may cause mania and a severe increase in blood pressure.

The FDA issued a public health advisory in November to warn people of the risk of bleeding in the brain from use of this medication and urged all manufacturers of this drug to remove it from the market. Most drugs that contained phenylpropanolamine have been reformulated without it.

Quinolone antibiotics. Green tea may make these medications more effective and also increase the risk of side effects. These medications include:.

The shpplement follows a federal GGreen reviewprompted after Madeline Papineau, a year-old in Cornwall, Ont. Doctors were initially stumped by the damage, until the teen's sister mentioned she'd been taking a diet supplement. Health Canada says the risk of liver injury has been noted on the labels of products containing green tea extract since But on Wednesday the agency announced it was "clarifying warnings" by asking manufacturers to include the following stronger wording on their product labels:. As part of a previous investigation, CBC's Marketplace discovered more than 60 documented cases worldwide of liver failure associated with green tea supplements reported in peer-reviewed journals.

Green tea supplement -

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.

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 , In a summary of its safety review findings issued on Wednesday, Health Canada said that although they are rare, "cases of liver injury continue to be reported in Canada and worldwide.

It said it knew of 11 cases of suspected liver injury associated with green tea extract in Canada between and , although only two of those cases "had enough information to be fully assessed. What remains unclear from the evidence, Health Canada said in an accompanying news release,"is why some people may be more susceptible than others to liver injury.

Health Canada is now asking, "as a precautionary measure," that companies licensed to make "natural health products containing green tea extract as a medicinal ingredient and that are intended for children and adolescents" either remove the green tea extract or revise the label to specify that the product is only intended for adults over 18 years of age.

Julie Papineau, Madeline Papineau's mother, said she is pleased with the stronger warning on green tea extract products but feels it doesn't go far enough.

The department says that green tea "in any form, including as beverages, foods and an extract in natural health products, is considered generally safe for the majority of consumers.

Joyce Boudreau-Hearn, of Mulgrave, N. Her daughter, Jocelyn Stewart, says the year-old had been healthy before she started taking a green tea extract sold as a weight-loss supplement.

You think you will lose a few pounds. She lost her life. While there are documented cases of the dangers, there are few examples of green tea extract actually aiding in long-term weight loss. Sean Wharton, the medical director of several publicly funded weight-loss clinics in the Greater Toronto Area, describes weight-loss supplements as "hope in a bottle.
