10 Best Green Tea Extracts Tested & Fully Reviewed

0

Green tea offers a plethora of health benefits, and it’s no surprise that many athletes make sure to incorporate green tea or green tea extract into their diet!

It also provides our bodies with powerful antioxidants that improve our immune system, heart health, assist us with fat loss. In fact, it is packed with Epigallocatechin (EGCG)—a natural phenol and antioxidant.

An extract is simply a concentrated version of green tea—it’s 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.

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.

The Criteria We Used To Find The Best Green Tea Extract

Ingredients

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

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.

Certifications

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.

 

A Few More Things To Think About

The following factors should be considered when choosing the right green tea extract for you.  The following are factors that depend on personal preference, so keep them in mind before selecting a green tea supplement.

Caffeine

Green tea naturally contains caffeine. Some runners love the boost of caffeine before a workout, while some athletes have a caffeine sensitivity or do not want the additional caffeine in their diet. It can cause upset stomachs and make some too jittery. Even though green tea extract naturally contains caffeine, some companies decaffeinate their product. Runners should look for the product that works best with their lifestyle.

Format

There isn’t anything wrong with getting your green tea through its most natural state, steeped 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.

Dietary Supplement

Green tea extract has been proven to speed up metabolism. Because of this and its caffeine content, green tea extract is considered a dietary supplement. Many individuals have found success in weight loss by eating a balanced diet, exercising and adding a green tea extract to their healthy lifestyle. Athletes should be aware though that some lower quality products will increase the caffeine content or add dangerous artificial ingredients to their supplement. Always read the labels.

 

FAQs

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.
