Green tea extract benefits -

A study of adults in China associates regular green tea consumption with better cognitive function, particularly executive function and memory.

Several smaller studies support this. A study suggests acute green tea extract supplementation improved working memory capacity in 10 women ages 50—63, although there was no significant effect for younger adults.

Similarly, another study examined the effect of green tea catechins on adults ages 50—69 in Japan. The authors suggest daily green tea supplementation may benefit working memory.

According to a review , certain amino acids in green tea have an anti-stress element that helps to slow brain aging. This may be due to the neuroprotective effects, including anti-inflammation and anti-oxidative stress, of certain catechins in green tea. Green tea may also benefit other conditions.

For example, the United States Food and Drug Administration FDA has approved a green tea extract ointment as a prescription treatment option for genital warts. A review suggests green tea phytochemicals may reduce skin aging.

Other research suggests green tea may have the following effects:. Unsweetened brewed green tea contains fewer than 3 calories per cup. Green tea contains a relatively small amount of caffeine, approximately 29 milligrams mg per 8-ounce cup, compared with black tea, which has around 47 mg per cup, and coffee, which has about 95 mg per cup.

The caffeine in a cup of tea can vary according to the duration of infusing time and the amount of tea infused. Green tea contains one of the highest amounts of antioxidants of any tea. In adults, there are few known side effects associated with drinking green tea.

However, the following risks and complications are important to note:. Most research suggests that the rare cases of liver injury from green tea extract consumption are idiosyncratic reactions.

Reviews of these instances have yet to conclude direct causality. The Food and Drug Administration FDA does not regulate green tea supplements. As a result, these supplements may contain other substances that are unsafe for health or have unproven health benefits. Further research is necessary to determine the best time to drink green tea.

However, since green tea contains caffeine, some people may prefer to drink it in the morning. Research suggests it is safe for most adults to drink up to 8 cups of unsweetened green tea daily.

However, people should be aware of the amount of caffeine in the brand they choose. Some research suggests that regular tea consumption, including green tea, may help to reduce body weight and waist-to-hip ratios.

However, several factors can influence fat loss, including total calorie intake and exercise levels. Green tea may have several health benefits. For example, it may help with weight management, skin inflammation, and type 2 diabetes. Some research also links green tea consumption to improved cardiovascular health.

Green tea has one of the highest concentrations of antioxidants of any tea. It is naturally low in calories and contains less caffeine than black tea and coffee. Most people can drink green tea daily with no side effects. However, some people may experience sleep disturbances due to the caffeine in green tea if they drink large amounts or consume it late in the day.

Do you enjoy tea for its flavor or the soothing feeling brought by holding a steaming cup? In this Spotlight, we tell you which brews are best for…. Matcha is a green tea powder that people tend to use in traditional tea ceremonies.

Modern uses include flavoring smoothies, cakes, and lattes. It may…. Green tea pills contain high concentrations of tea catechins, flavonoids, and green tea polyphenols, which are antioxidants. Catechins speed up metabolic rate.

This helps trigger the release of fatty acids, which the body breaks down into energy. These compounds essentially encourage the body to burn existing fat stores to produce energy. Catechins may help to control body weight - especially when in high concentrations such as green tea pills or matcha green tea from Japan.

Studies show that the main driver behind these health benefits is EGCG or epigallocatechin gallate — particularly epigallocatechingallate.

This tea catechin works to increase body temperature, which signals the body to burn fat more quickly. This results in increased fat loss, simply by drinking green tea or taking a green tea capsule. This natural fat burner works best when caffeine consumption remains below mg of caffeine per day.

Green tea extract supplements also may be more effective for some ethnicities. A meta analysis published in the International Journal of Obesity found that green tea extract effects were more pronounced in individuals of Asian decent 1.

While the benefits are more pronounced for some individuals than others, consuming green tea or taking green tea pills can help you lose weight. Drinking green tea can speed up the effects of thermogenesis, thus helping to encourage fat oxidation and decrease body fat. When combined with a healthy diet and exercise regimen, these fat burner pills may also help maintain a healthy weight.

Green tea extract supplements contain antioxidant properties that help to cleanse the body of free radicals. Free radicals are uncharged cells that are highly reactive in the human body. Free radicals pair with damaged or deteriorated cells and can wreak havoc when it comes to health.

Free radicals cause oxidative stress—the body's form of rust—and have been linked to cancer, liver damage, premature aging, and heart disease. The antioxidant EGCG in green tea supplements helps to block free radicals. A study published in the European Journal of Nutrition found that athletes who took green tea extract had significantly lower levels of oxidative stress after intense exercise 2.

In the United States alone, almost 2 million new cases of cancer are diagnosed each year. With increasing prevalence, it's no wonder that Americans are constantly looking for ways to prevent the onset of cancer.

While green tea may play a role in cancer prevention, more research is needed to determine the agents and efficacy of the pills. Researchers also haven't established the number of mg of green tea extract needed to produce cancer preventative effects.

Green tea pills may help lower your risk of cancer thanks to its free-radical fighting properties. Most research has been conducted in the lab or on animals, although there are a few human clinical trials.

Green tea extract also works most effectively on certain types of cancer including breast cancer, prostate cancer, and liver cancer. A study published in the Journal of Nutrition found that green tea extract prevented the growth and proliferation of breast cancer cells in the lab. An epidemiologic study published by the American Association for Cancer Research analyzed the effects of green tea on colorectal cancer.

The study consisted of almost 70,00 Chinese women who were examined over the course of six years. Researchers found that the women who consumed the most green tea had the lowest rates of colorectal cancer 3.

The findings of another large study were published in the American Journal of Clinical Nutrition in Yang and his team of scientists researched 3, incidences of cancer among 38, women over a period of 11 years.

During the course of this study, researchers found that tea catechins were correlated with lower risk of cancer 4. Taking green tea extract may protect against heart disease thanks to its anti-inflammatory properties.

Green tea contains active ingredients such as antioxidants that help to reduce inflammation that can lead to high blood pressure and clogged arteries — risk factors of cardiovascular disease.

When blood vessels become inflamed, they reduce the movement of blood cells within arteries. This results in tighter passages that are more easily clogged, leading to heart attacks and blood clots.

Green tea antioxidants reduce inflammation to keep arteries open and clear. Studies also show that green tea pills can help lower bad cholesterol known as LDL cholesterol. People taking green tea extracts, especially those with liver disease, should discontinue use and consult a health care provider if they develop symptoms of liver trouble such as abdominal pain, dark urine, or jaundice.

Green tea is an ingredient in many over-the-counter weight loss products, some of which have been identified as the likely cause of rare cases of liver injury. Green tea at high doses has been shown to reduce blood levels and therefore the effectiveness of the drug nadolol, a beta-blocker used for high blood pressure and heart problems.

It may also interact with other medicines. Keep in Mind. Take charge of your health—talk with your health care providers about any complementary health approaches you use. Together, you can make shared, well-informed decisions.
