10 Best Green Tea Extracts Tested & Fully Reviewed

last updated Feb 10, 2019
Green tea provides our bodies with powerful antioxidants that improve our immune system, heart health, and even assist us with fat loss. The best green tea extracts are also packed with Epigallocatechin (EGCG)—a natural phenol and antioxidant. Green tea extract is simply a concentrated version of green tea—which makes it easier to fit into your daily routine, can be taken on the go, and provides you with all of the same health benefits.

The caffeine and powerful antioxidants found in the best green tea extracts have been proven to improve your overall brain function, boost your metabolism, and reduce breast, prostate, and colorectal cancer rates. With all of these benefits, it makes sense to incorporate a green tea supplement into our diets.

Criteria Used for Evaluation

Features

It is important that we went over the entire ingredient list of each product we reviewed. Since green tea extract can be marketed as a dietary supplement, some brands will try to sneak fillers and artificial ingredients. On the other hand, some include vitamins with the green tea extract. This isn’t a bad thing, per se, but it is important that we highlight all ingredients in a product to inform the consumer of what they are getting.

Value

The cost of each green tea supplement was considered when choosing the products on our list. We looked at the price per serving, as well as what the recommended serving size of each product was. Finally, we looked at the purchasing options for each product including whether or not the product was available in bulk or if it was readily available for purchase in general. It was an important part of our process to assess the value of each product and help you find the best green tea supplement that fits your budget.

Product Purity

We looked at a few different variables for this category. Many athletes have different dietary needs and restrictions. It was important to highlight which products were certified as vegan, vegetarian, soy free, dairy free, gluten free, kosher and/or none-GMO. In addition to this, we looked at products that passed rigorous health standards such as being produced in an FDA approved facility or being inspected by third-party manufacturers.

Application

There isn’t anything wrong with getting your green tea through its most natural state, steeped in green tea. However, green tea supplements make getting the benefits of green tea easier. The three types of green tea supplements are a capsule, a powder, or a liquid. Each system has its pros and cons, but overall, it’s personal preference. Some can’t stomach the taste of the powder while others hate taking pills. Some love the convenience and taste of the liquid. Consider your lifestyle and what works best for you.

Switch out your coffee

Green tea can be a great replacement for your morning coffee, for its caffeine content. Plus, you'll get so much more from it than your regular cup of Joe. You will also enjoy a boost to energy levels and overall metabolism without the jitters and annoying crash that comes with caffeine and other stimulants.

Don't forget to hydrate

If you're taking green tea supplements, don't forget to drink more water, as it's still a diuretic. If you have issues with water retention, kidney or bladder issues, or other health considerations it is important to make sure you talk to your doctor before you start taking green tea supplements or any other supplements.

Other Factors to Consider

Safety Hazards

Caffeine and powerful antioxidants found in the best green tea extracts have been proven to improve your overall brain function, boost your metabolism, and reduce breast, prostate, and colorectal cancer rates. With all of these benefits, it makes sense to incorporate a green tea supplement into our diets.

That being said, it’s important to be able to distinguish between the best green tea extracts and the lower quality supplements also available on the market. These low-quality supplements often may include high amounts of fluoride, unnecessary fillers, and unwanted appetite suppressants.

Frequently Asked Questions

q: What are the health benefits of Green Tea Extract?
a:

The most notable health benefit of green tea is that it is a great source of antioxidants. It also improves immune function, reduces cancer risks, promotes fat loss, and improves heart health. The component of green tea that offers the most health benefits is Epigallocatechin gallate, or EGCG, which is a type of antioxidant and natural phenol.

q: Why can’t I just drink green tea?
a:

You could! There is nothing wrong with drinking green tea, but you would need to drink 3-5 cups a day to get the same health benefits as taking one or two green tea extract capsules or powder. Green Tea Supplements may be a more convenient option for those looking to get the health benefits of green tea, but cannot or do not want to drink 3-5 cups of green tea every day.

q: Can green tea extract be dangerous?
a:

As with anything, too much of a good thing can be bad. In very high doses, green tea extract can be damaging to a person’s liver function. Also since green tea naturally contains caffeine, too much of it can make some people jittery. Some individuals also complained that green tea extract in concentrated doses caused them an upset stomach.

q: Are there different ways to take a green tea extract?
a:

Yes! The most popular is a capsule. It is easy to ingest and masks the unpleasant taste. Another option is a powder which can be mixed with drinks or other foods. Finally, green tea supplement can also be a liquid which then can be mixed with warm or cold water. Our list above includes one or more of each.

q: Do I need to take green tea extract?
a:

No. There isn’t a health requirement, but it does contain high levels of cancer-fighting antioxidants that can have major health benefits. As with all supplements, be sure to talk to your doctor before starting a new supplement.
