Clinical Trials Registry

Our Philosophy

We established criteria to provide assurance to investigators, clinicians, and patients, as well as the editors and readers of medical publications to whom we submit our data, that we are publishing comprehensive, balanced, and accurate information about our investigations. The goal of these principles is to guarantee that we generate publications in a responsible and ethical way on a consistent basis.
We are neutral towards the results and conclusions of the trials.

Green tea extract is a highly concentrated form of green tea. Rather than infusing the tea leaves in water like you would to make a cup of tea or blending them into a powder to make matcha, caffeine and catechins are extracted from tea leaf scraps and emulsified into a powder. Some companies will strip the antioxidants and caffeine from the leaves themselves instead.

Specifically, green tea contains flavonoids. Flavonoids are the largest group of polyphenols, containing over 5,000 different compounds that affect everything from coloring to taste to metabolites. These include:

The differences between green tea extract and steeped tea play out in dosing. One cup of green tea made from a tea bag at home has about 100-150mg of polyphenols (about 75% of which are EGCG when brewed correctly). High-quality green tea extracts range from 45% to 50% EGCG, resulting in a lower EGCG-to-polyphenol ratio but more EGCG overall.

Most studies look at the amount of EGCG in each serving to determine a healthy dose. Taking about 350mg of EGCG daily is often enough to receive these benefits without any harm, though studies have shown that you can take up to 675mg without risking your health. Doses upward of 800mg EGCG daily (or about 1,500mg of green tea extract per day) can cause liver damage in some people.

Green tea extract is more stable long-term than brewed green tea. Green tea is best brewed at a low temperature (about 180 F). Once you begin steeping the tea, its polyphenols start to degrade. This occurs faster at higher temperatures. Green tea extract preserves a vast majority of these (between 95 and 98% on average), allowing you to get the most benefit without pulling out a thermometer every time you want a cup of tea.

On the other hand, solids (including powders inside capsules like most green tea extracts) are harder for your body to digest. It takes a while to break a solid into small, soluble pieces, and the longer it takes to reach peak solubility, the more proteins and chemicals degrade before you can use them. This means that while green tea extract might get you more polyphenols faster, your body might not be absorbing them in the same way. Most extracts have enough polyphenols to offset this, however.

There are a few problems that can stem from taking green tea extract. Most of them occur when you take a high dose (2,000mg or more) every day and are made worse by taking them on an empty stomach. Be sure to take your green tea extract with food to avoid stumbling into adverse side effects.

The National Institutes of Health recommends staying away from green tea extract if you take beta-blockers like nadolol. In high doses, green tea can lower the amount of blood in your body, so it interacts poorly with medications used for high blood pressure and heart problems.

These liver problems are more likely to occur when you take more than 800mg of EGCG per day. If you have a history of liver disease or a family history of acute liver failure, talk to your doctor before starting a green tea extract.

Zenwise provides an uncompromising green tea extract with a few bonuses. Each container holds 120 servings (one capsule per serving) of 725mg green tea extract. It has 95% polyphenols and 50% EGCG; this is one of the most potent extracts on our list, though there are higher polyphenol concentrations. Each serving also contains 60mg of vitamin C as ascorbic acid for an extra immune system and antioxidant boost. One serving also only has 15mg of caffeine, which is about the same as one cup of brewed green tea.

If you want to buy a substantial amount, Bulk Supplements also offers bundles of multiple 2.2lb bags at a time. You can get five (11lbs) or 25 (55lbs) bags at a time. Their 55lb option is frequently out of stock, but you can order 11 pounds of green tea extract powder for less than $250.

Polyphenols are the broad category that catechins and EGCG fall into, and EGCG is a kind of catechin. When a green tea extract labels itself as having, for example, 95% polyphenols and 50% EGCG, it means that, of the entire serving, 95% of the extract is polyphenols, and 50% of that total is EGCG.

You can find green tea extract in a variety of forms, such as capsules, powders, and liquids. Typically, capsules are preferred over other forms due to their convenience. We recommend choosing the form that best fits your lifestyle and needs.

The addition of a thermonutrient can make an effective green tea extract even more effective by increasing absorption to deliver quick results. You should look for an extract that is enhanced by a thermonutrient like caffeine or guarana.

Green tea extracts contain powerful antioxidants that hunt down harmful toxins and byproducts that can damage cells, which may cause cancer. These same antioxidants have also been shown to reduce the risk of heart disease.

The Zenwise Green Tea Extract is a powerful supplement containing 95% polyphenols and 50% EGCG. Each container comes with 120 capsules with a single serving of 725 milligrams of green tea extract and 60 milligrams of vitamin C. The additional vitamin C acts as an antioxidant boost to improve the immune system.

This green tea extract is a highly concentrated extract so you can get maximum benefits from the formula. This formula is perfect for giving you an extra energy boost while supporting your immune system. This extract also supports your heart health and the powerful polyphenols and antioxidants it contains will enhance your natural energy levels. As an added bonus, this bottle contains 240 capsules, which is the highest quantity on our list.

Besides a super-clean formula, this extract follows the standardized percentages of ingredients, containing 95% polyphenols, 75% catechins, and 45% EGCG. Each bottle contains 180 capsules made with safe and healthy ingredients at an affordable price.

For those who cannot swallow large pills, the NOW Green Tea Extract is perfect with its easy-to-swallow capsule size. Each bottle contains 180 vegan capsules, and every capsule has 400 milligrams of green tea extract. This concentration of green tea extract is relatively low but works well for those who take it regularly.

A: Green tea extract pills are generally safe when used as directed. There have been some reports of liver damage in those who have taken green tea supplements. If you take green tea extract pills, be sure to follow the package directions carefully and talk to your doctor if you have any concerns.

A: Green tea extract is usually orange in color. The color depends on the manufacturing process and the type of tea used. Some companies use extraction as the primary source of getting the polyphenols instead of grinding the green tea leaves, which leaves an orange tint behind.

A: Green tea is the pure form of the leaf. Green tea extract is a concentrated version of green tea. The extracts tend to have more potent polyphenols called catechins and other nutrients.

Matcha is grown and processed differently than conventional green tea. Due to these differences, matcha may retain higher concentrations of polyphenols compared to brewed green tea, especially if it's made from first harvest leaves. Matcha also typically has a higher caffeine content than other green teas.

The antioxidant compounds in green tea are a type of catechin polyphenol, called epigallocatechin-3-gallate (EGCG). These naturally occurring flavonoid antioxidants can reduce oxidative cellular damage in the body by blocking inflammatory pathways. Green tea also contains L-theanine, which has been shown to have cognitive-enhancing and stress-reducing properties. Additionally, some evidence suggests green tea may modestly help burn fat, due to the combination of EGCG and caffeine; however, more research is needed to support these claims.

Green tea contains caffeine, so it is best to drink it earlier in the day to avoid any sleep disturbances. Swap a cup of brewed green tea or matcha for your cup of coffee in the morning for a gentle caffeine boost.

You may also choose to time your green tea consumption based on your workout, since drinking 3 to 6 milligrams of caffeine per kilogram of body weight 60 minutes before exercising may improve exercise performance.

The antioxidant compound in green tea, EGCG, is in both caffeinated and decaffeinated green tea; however, decaffeinated tea may have lower concentrations of antioxidants due to the processing it undergoes. There are two main methods used: direct chemical solvent and supercritical carbon dioxide decaffeination. If you can, choose a decaf green tea brand that uses the carbon dioxide method as it preserves the most polyphenol content.

The caffeine content of green tea products varies, but generally, eight ounces of brewed green tea provides 20 to 50 milligrams of caffeine, compared to about 80-100 milligrams in coffee. Matcha tea typically has higher concentrations of caffeine, with about 70 milligrams per teaspoon of powder (a typical serving size for an 8 ounce cup of tea).

According to the FDA, up to 400 milligrams of caffeine a day is considered safe for healthy adults. This is equal to about eight cups per day of green tea or four cups a day of coffee. However, note that each person has a different tolerance for caffeine, so be sure to take note of how you are feeling and adjust your intake if needed.

While some evidence suggests green tea may have possible, modest effects on weight loss and fat oxidation, due to the combination of EGCG and caffeine, more research is needed to support these claims. However, sipping on green tea can be a part of a balanced diet, particularly if it is offsetting consumption of sugar sweetened beverages. It is important to note that green tea beverages are different from green tea extract supplements, which are not supported by the CDC for weight loss and may come cause negative side effects. 041b061a72
