Thermofight X Fat Burner Review – Does it Work?

Thermofight X review - Does This Fat Burner by It Works work?

Welcome to our Thermofight X review, a fat burner from the Next Gen line manufactured by It Works!

Priced at a whopping $67 per bottle, it promises to help you:

  • Lose an average of “31 pounds in 90 days”
  • “Accelerate ketosis by supporting rapid ketone generation”
  • Activate thermogenesis
  • Boost energy levels

Phew… those are some big promises! Can Thermofight X pills really do what they’re claimed to do? And are they safe?

We’ll give you our short summary first, followed by a more detailed analysis below.

Pros and Cons

In a hurry? We’ve found It Works Thermofight X to be a huge disappointment.

The marketing claims are misleading, they promise all of these benefits but use ingredients that are completely ineffective for weight loss.

They also masked some ingredients’ doses so we aren’t able to see their amounts.


  • Green tea is good for energy and focus
  • Chromium and cinnamon bark help balance blood sugar levels


  • Lacking more proven ingredients
  • Many ineffective ingredients, some are underdosed as well
  • Contains two proprietary blends
  • Doesn’t have an appetite suppressant
  • Ridiculous price, between $67-$100 for a one-month supply

How Does Thermofight X Work?

Thermofight X is a product that works by triggering a so-called process of “thermogenesis” in your body. What does this mean?

Essentially, your body’s core temperature will rise, which in turn leads to an increase in metabolic rate as your body tries to cool itself down.

Thermofight X also promises to help you tap into your stored body fat and start ‘melting’ it away as energy.

There’s almost no mention of appetite suppression, though. Which is disappointing considering that a big part of weight loss is controlling cravings and caloric intake.

So, how will it work for you? Let’s take a closer look.

Thermofight X: The Ingredients

Each Thermofight X pill supplies you with the following active ingredients:

  • Calcium (140mg)
  • Chromium (200mcg)
  • Proprietary Green Tea Blend (302.5mg)
  • Green Coffee Bean Extract (100mg)
  • Proprietary Thermogenic Blend (75mg)

What’s disappointing is that some of the ingredients are found in so-called proprietary blends. These prevent us from knowing the exact amounts of each ingredient in them.

Here’s a closer look at the ingredients themselves:

1. Calcium

This is a filler ingredient. It doesn’t have any significant effects on weight loss. It might help your bone health but that’s about as good as it gets!

2. Chromium

Chromium is good for your blood sugar. Especially after a meal high in carbohydrates. Typically, following that kind of meal, we’ll feel groggy and lethargic due to the blood sugar spike and subsequent insulin spike.

Consuming enough trace minerals like chromium can slightly balance this out, so blood sugar doesn’t spike as high. [1] While it’s nothing spectacular, and doesn’t make you burn more fat, it can be beneficial for helping to prevent weight gain.

3. Proprietary Green Tea Blend

Here we come to the first proprietary blend in Thermofight X. As we said, it’s a mixture of ingredients that only shows as a single dose on the label. AKA, the combined dose of all the ingredients in it.

With this particular proprietary blend, that’s not that big of a deal as it’s all green tea basically. So you know you’re getting about 300mg of green tea extract here. This is a safe and well-tolerated dose of the ingredient, so that’s good. [2]

But below you’ll see us dissect another proprietary blend which is a completely different story.

4. Green Coffee Bean Extract

This ingredient helps with carb absorption. Specifically, it makes your body more efficient at processing carbs so you don’t store as much of them as fat, but instead burn them for energy. [3]

5. Proprietary Thermogenic Blend

Here’s the proprietary blend we’ve been talking about. It consists of 5 ingredients in unknown amounts, they include:

  • Cinnamon bark extract
  • Trikatu
  • Ginger Root and Long Pepper
  • Cayenne Pepper

The entire proprietary blend weighs only 75mg, so at least we can tell it’s not going to cause any major side effects. However, since the dose is so low, it won’t do much good either!

The ingredients themselves are ineffective for fat burning, expect for cayenne pepper which is one of our top rated thermogenic ingredients. [4] It needs to be dosed at 150mg or higher, though, which is double the amount of this entire proprietary blend.

Our Thoughts on the Ingredient Profile

It’s disappointing. We don’t like that they’ve hidden most of the formula behind the proprietary blend so you can’t see how much of each ingredient you’re getting.

It has a few good ingredients such as green tea, green coffee bean, and cayenne pepper, but the latter is dosed too low and so it doesn’t do much for thermogenesis (aka, fat burning).

Green tea can help with focus and energy, and green coffee bean makes you feel a little more satiated, but that’s as good as it gets with this supplement. It’s missing many core ingredients that would make it more effective at actually burning fat.

The Three of the Best Fat Burners of 2020

How to Take Thermofight X

Thermofight X dosage instructions are to take 1 capsule, two times per day with a glass of water.

This is better than what most fat burners offer – just 1 daily serving – but it’s still not enough to maintain the effects throughout the day.

You want to be taking 3-4 servings per day to keep the beneficial ingredients circulating in your system between the doses. When you only take one or two servings per day, the effects will wear off and you won’t be in a continual fat burning mode.

Does Thermofight X Have Side Effects?

Thermofight X should cause side effects for most people.

The ingredients themselves are well researched and known to be safe. Many of them, like cinnamon, are used in daily cooking.

The doses are also light, too light in some cases, so you shouldn’t worry too much. There aren’t any stimulants in this product either, which is good for people who want to avoid caffeine.

Thermofight X Before and After Results

So, what results can you expect from taking Thermofight X, say, for 4 weeks? Well, not much! Our personal experience wasn’t that great.

Me (Quin), Gabriel, and Anja all trialed it for 5 weeks with no success. The only change we noticed was a boost in mental focus due to green tea extract and L-Theanine in it. Other than that, our before and after weigh-ins looked the same so there’s not much to say in that regard.

In terms of other people’s before and after pictures, most of it is sponsored by “It Works!” Thermofight X, so it’s hard to tell which ones are legit, and which ones are BS. If you ask us, all of them are BS as this product doesn’t use the kinds of ingredients that would result in anything close to what these before and after photos show.

But here’s a look at some of them if you’re still curious:

Thermofight X Customer Reviews – What do Others Say?

Some people are wondering whether they are any Thermofight X reviews in Canada, UK and other countries outside of the USA.

The answer is, there are – however, you’ll need to keep your eye on what’s legit and what’s fake.

It can be hard to tell as many reviews are manipulated to make the product appear worse or better than it actually is.

This is why we don’t like to rely on other user’s testimonials in the first place, and prefer to base our opinion off the ingredients and the evidence behind them.

Thermofight X Review Summary

Here the conclusion of our Thermofight X review.

What can we say? It’s not quite what we expected it to be. Thermofight X has a lot to improve before it can compete with the best fat burners on the market.

The price is just ridiculous, $67-$100 dollars depending on the discounts is just absurd considering its low quality and lack of proven ingredients. Not to mention the use of proprietary blends which completely ruins the It Works! image for us.

Thermofight X is best left alone.
