Pros:

Vegan

EGCG

Affordable

Increases health and focus

Non-GMO

Cons:

Has caffeine

This product has quickly become well known because it is a high-quality product made of organic ingredients and has a minimum amount of caffeine.

Read more

Dietary Effects

This one offers many health benefits and helps you lose weight, increases your brain function and focus, and generally improves your overall health.

Side Effects

While this supplement doesn't have a lot of caffeine, it can still cause you to get jittery and fidgety if you are sensitive to it.

Cost and Value

The supplement is super affordable and costs about 14 cents per serving. Moreover, the purity of ingredients and effects make it extremely valuable.

Pros:

No extreme side effects reported

Customers who also drink green tea say the benefits are similar

Cheapest price point of the reviewed products

Increases energy and appetite

Cons:

Insomnia is a regular complaint when taken too late in the day

As we get towards the middle of the list, we start to find supplements that sacrifice one aspect of a perfect supplement for another. While NOW's standard green tea isn't going to beat out some of the higher end supplements in performance, it certainly is an attractive choice for the more frugal, health conscious person. Overall this is a decent supplement that does precisely what it ought to do, increase your energy and decrease your appetite.

Read more

Dietary Effects

While NOW created a supplement that effectively raises energy and kind of suppresses appetite, it basically missed the mark in the fat burning department, and this is evidenced by the numerous reviews stating little to no effect in the weight loss category, barring using this in conjunction with a proper exercise regimen. If weight loss is your primary concern, there are better options to explore.

Side Effects

As with any caffeinated supplement, the big concern with this green tea is jitteriness, and potential inability to sleep if taken at an inappropriate time. Few customers reported any nausea or headaches.

Green tea/EGCg/ Polyphenol Content

While the green tea content is comparable to others at 400mg, the EGCg content is only about 40%, or 160mg of the total supplement. This accounts for the mild effects.

Cost and Value

At a measly .06 cent per serving average, this is by far the most cost-effective option out of the supplements we've reviewed.

Cons:

Contains caffeine

While this one is geared towards weight loss it is an excellent option to increase your overall health and get an energy boost while you're at it.

Dietary Effects

This one encourages steady weight loss and provides you with a boost of energy to get you through the day.

Side Effects

If you are sensitive to caffeine then this one might cause of jittery feelings and may even keep you up if you take it too late in the day.

Cost and Value

This product comes to about 27 cents per serving. However, most athletes prefer it because of its favorable caffeine levels.

Pros:

Cons:

Potency has been linked to an aftertaste for some

The Zhou Nutrition green tea supplement is a great option for those who are looking for a good supplement that wont cause stomach upset. This potent powder might be for you and it can deliver the energy and metabolism boost you have been looking for!

Read more

Accuracy
It is important to ensure that with any supplement the ingredients are pure and the labels are accurate. The combination of caffeine and L-theanine in this supplement has been shown in trials to have synergistic effects that help support brain function, including mood and alertness.

Potency
Zhou Nutrition’s product contains a high level of polyphenol catechins and the powerful Epigallocatechin gallate (EGCG) which is known to help support healthy cell growth and healing. These potent elements also help promote and support healthy fat oxidation.

Value
This supplement is fairly reasonably priced compared to others of similar strength and capsule count. Suggested service in 1 capsule a day and there are 120 capsules in a bottle so you are more than getting your money’s worth when you invest in this green tea supplement!

Purity
The final thing reviewers like about the this is that it is easy to take, gentle on the stomach and made from quality ingredients without any stimulants like caffeine.

Pros:

Powdered supplement - mixes well in every medium

No flavor

Non-GMO + MSG free

Lab tested and verified

Cons:

Some customers report a bitter aftertaste

BulkSupplements Pure Green Tea Supplement starts our list, and of all the products reviewed, this one can be mixed to just about any drink you can imagine. It can also be found for a very reasonable price, but more importantly, it's frequently reviewed as being highly effective.

Read more

Dietary Effects

BulkSupplements is on to something with this product. Almost every customer who reviewed it felt that it had some effect on their energy, weight loss, and appetite suppression. Customers also reported a quick onset, so you can take this supplement without having to worry about when it'll kick in.

Side Effects

Side effects were very rare with this supplement, almost entirely being regulated to a sense of jitteriness.

Green tea/EGCg/ Polyphenol Content

Of the reviewed products, this supplement had the second highest green tea content at 696mg per serving, and one of the higher polyphenol contents at 300mg per serving. The manufacturer did not provide an EGCg content

Cost and Value

For a powder, this supplement can be found for a remarkably reasonable price at roughly .10 cents a serving, of which there are about 500.

Pros:

Made in an FDA approved facility

Reports from some customers claim to have seen a drop in cholesterol levels

Slightly higher caffeine levels

Little known side effects

Cons:

A bit pricier than other options

Less EGCg than other options

Green Tree Life Sciences premium green tea supplement is, above all, a very stable, and mild supplement that won't give you much in the way of negative effects. While the benefits are marginal, for those of us with little tolerance for stomach aches, headaches, or the jitters, this is a very attractive option.

Read more

Dietary Effects

As with a lot of other supplements, the strength of this product is that it effectively mitigates appetites for a prolonged period of time, but conversely, it does little in the way of increasing energy and has hardly any direct benefit to weight loss.

Side Effects

While Green Tree Life Sciences makes sure to warn against all the standard issues of green tea supplements, very few, if any people actually had any complaints about anything short of stomach irritability.

Green tea/EGCg/ Polyphenol Content

500mg of green tea seems to be the industry standard as far as things go, but the 40% EGCgs and 75% polyphenols are towards the low end of the spectrum. IT is worth noting that the supplement does have a higher than normal 5% naturally occuring caffeine.

Cost and Value

At 20 cents a serving, this is certainly on the higher end of the products reviewed, and given the middle of the road results gained from taking them, some people might be less likely to want to invest in this product.

Pros:

Decaffeinated - less than 1% caffeine per pill

Produced at an NSF certified facility

High level of thiamin to aid in cognitive function

Quite affordable

Cons:

The thiamin is bad if you have high blood pressure

Rough on the stomach

For those of us who can't have, or are sensitive to caffeine, we've got Buddha's Herbs Decaf green tea, a supplement that generally got rave reviews, with little in the way of negative comments.

Read more

Dietary Effects

While the effects of this supplement are generally viewed as mild, they are also consistent across the board with buyers noting that they experienced significant increases to their energy, as well as moderate appetite suppression and fat burning.

Side Effects

This pill is great for those of us who are sensitive to caffeine, as less than 1% of the capsule contains the jitter-producing substance. Additionally, Buddha's Herbs supplements are well regarded as being generally soft on the stomach.

Green tea/EGCg/ Polyphenol Content

If you're looking to this supplement for high levels of green tea, or EGCgs, then you may want to consider another source. The GTC is about 400mg per serving, with about 200mg of EGCgs. This may have something to do with the mild effects.

Cost and Value

At an average cost per serving of .08 cents, this is a very affordable option for anybody. Moreover, it still boosts energy and boosts performance.

Criteria Used for Evaluation

Accuracy

This category looks at a few different factors, but primarily focuses on how well the supplement affects your body’s ability to burn fat, how it promotes appetite suppression, and how whether or not there was a noticeable increase in energy throughout the day. In addition to that, we also paid special attention to pills that were reviewed as having a particularly strong impact on things like allergies, skin health, and other conditions that aren’t mentioned in the products descriptions.

Potency

As the title would suggest, this category looks at the adverse effects that taking it had on customers who bought it, including, but not limited to indigestion problems, cases of the jitters, nausea, inability to sleep and headaches. Since these are all common side effects of these kinds of supplements, the severity of the effects was what we paid attention to during evaluation.

Value

This is simply how much the product costs per serving. We’ve taken into account whether or not a serving includes multiple pill/scoops of the product, which may explain why our metric looks slightly different than the one on the bottle.

Product Purity

This metric is meant to provide you with some idea of how much green tea is in the supplement, as well as its Epigallocatechin gallate (EGCg) content, and any polyphenols. While claims supporting the effectiveness of EGCg, and polyphenols in regards to weight and energy are scarce, customers claim that supplements with increased levels of these substances had a better success rate.

Frequently Asked Questions

q: What are the side effects?

a:

As previously mentioned, before taking a supplement you ought to consult your physician, as it can have quite a few negative side effects if you suffer from certain conditions and/or take other medications. In fact, even if you don’t currently have a condition that warrants special consideration, green tea supplements can be rough on your system. They may worsen the effects of anemia, bleeding, or anxiety disorders, and have been linked to an increase in irregular heartbeats, most likely due to the caffeine. On the topic of caffeine, it has been linked to weakened bones, and irritable bowel syndrome (IBS).

q: Who shouldn’t take green tea supplements?

a:

As stated before, consult your doctor prior to taking a supplement. That being said, most people are going to be ok to take green tea supplements including pregnant women to a certain extent. However, it is not recommended that you take green tea if you’re breastfeeding. Also, it has not been extensively studied in children as of yet, so kids should avoid a green tea supplement unless specified by a doctor. If you have a heart condition, kidney problems, liver problems, ulcers or a psychological condition it is not recommended that you start taking these supplements.
If you are taking an amphetamine, or ephedrine based medications DO NOT take a green tea supplement as the combination of the two will speed up your heart rate, and your nervous system which will result in extreme jitters, and may even cause extreme changes to your blood pressure, and cardiac health.
Green tea supplements have also been shown to have negative interactions with a variety of medications such as benzos, beta blockers, blood thinners, lithium, and it may also decrease the effectiveness of treatments during chemotherapy. If you’re taking any kind of medication it’s worth giving your doctor’s office a call to make sure there are no interactions.

q: Why might I want to consider not taking it?

a:

Besides having an obvious health-related issue, there are a few things you may want to consider before picking up that bottle at your local health store. If your main goal is to lose weight, then this might not be the supplement for you. The main purpose of this supplement is to promote energy, and appetite suppression, and there is little in the way of scientific evidence to support that it effectively increases the body’s ability to burn fat, and it’s arguable that any effect seen may be due to the combination of the supplement, proper diet, and regular exercise.
Also, the concept of legitimacy is one that has to be discussed. While all the supplements we rated are from well-regarded companies, not all supplements are perfectly regulated. If the fact that the supplement industry isn’t regulated is a concern, you may want to avoid green tea supplements (and supplements altogether) as anything over 500 mg can be potentially harmful.
