That is why there are fat burner supplements out there. These kinds of supplements use what is called “thermogenesis” to burn fat. Thermogenesis is the result of increasing your body temperature by increasing the rate of metabolism. 

It Works Thermofight X is a fat burner designed by It Works. Thermofight claims that it can help burn through stubborn fats by activating thermogenesis and boosting the metabolism. Thermofight X claims it has science backing its formula but does it really?

Today we are going to talk about Thermofight X and answer some important questions such as its pros, cons, where to buy, and whether it’s worth the purchase.

It Works Thermofight X: Overview

Thermofight X is a thermogenic weight loss supplement. It is designed to boost your metabolism and burn fat. Thermofight X claims to be made from natural ingredients and increases your body temperature by boosting the metabolism. 

“Thermogenic” means “produces heat.” When the body burns calories, it increases body temperature. So thermogenic substances are designed to increase body temperature by increasing the rate at which your body burns calories. 

Thermofight X claims that it can:

  • Help dieters lose 31 pounds in 3 months
  • Activate thermogenesis
  • Boost your energy
  • Will help you lose weight. 

These are all pretty standard claims for a weight loss supplement. As always, none of these claims have been regulated by the FDA so we cannot take the company’s word for it. Each bottle of Thermofight X contains 60 capsules. You are supposed to take 2 capsules a day; once in the morning and once before workouts.

Who Makes Thermofight X?

Thermofight X is made by It Works, a US-based MLM company. It Works was founded by Mark Pentecost in Michigan when he was inspired by his own experiences with weight loss. The first product from It Works was a body wrap designed to slim fat around the waist. This was all despite the fact that experts agree that site-specific weight loss makes no sense. 

It Works is an MLM company which means it has a top-down hierarchical structure (almost like a pyramid…). Distributors have to pay $100 to get their start and the main source of revenue is selling products directly to clients and referring to new distributors. 

MLM companies get a bad rep and for good reason. Most of the time the people near the top of the structure do very well while the further down the chain you go the less likely you are to make money. MLM companies entice people with the promise of making big money, but the vast majority of people in these companies end up losing money. 

According to their BBB profile, It Works has a C+ RAting and an average of 2 out of 5 out of 251 customer reviews. They also have over 450 complaints all within 3 years. Pretty much every complaint is about bad payment and shipping practices such as customers being charged and not receiving products or orders to cancel being ignored.

How Does Thermofight X Work?

Unfortunately, it does not seem that It Works Thermofight X actually works very well. The majority of reviews are favorable, but the majority of non-favorable reviews are very negative.  The most common negative review is that the product did not work. Some reviewers claim the pills made them sick. 

Thermofight X claims it is proven to work but again, there are no clinical studies linked. It’s like one ingredient in the supplement has been tested and the company takes those studies as evidence that the product works. 

Of positive reviews, most people say that it helped them reach their weight loss goals. However, personal anecdotes are not scientific evidence.

It Works Thermofight X Ingredients

Thermofight X contains the following active ingredients:

  • B12: B12 is used for energy and plays a lot of roles in the human body. B2 has been linked to weight loss, though more evidence on this point is needed. 
  • Chromium: Chromium is a mineral that helps improve the production of insulin. It also plays a role in storing carbohydrates as fats. 
  • Raspberry Ketones: Raspberry ketones are common in weight loss supplements but there is no evidence that it can help humans lose weight. There is some evidence that it can help rats lose weight though. 
  • Green tea extract: Green tea extract is a stimulant that is linked to weight loss. Green tea extract also suppresses the appetite. 
  • Acai fruit extract: Acai-based supplements are very common in nutritional supplements, but there is little evidence about what benefits they have. 

Safety and Side Effects

Based on our research, the possible side effects of Thermfight X are:

  • Fast heart rate
  • Diarrhea
  • Nausea
  • Insomnia
  • Restlessness
  • Stomach pain
  • Dizziness

Many of these side effects can be attributed to the green tea extract and B12. It is also recommended that people under 18 and pregnant or breastfeeding women not take Thermofight X. 

Where to Buy Thermofight X and Cost

You can buy Thermofight X from It Works website or from third-party retailers like Amazon. You can also buy the product directly through an individual distributor though many people complain that this option ends up signing them up for subscriptions without consent. A single bottle of Thermofight X costs $100, ridiculously expensive in our opinion.

It Works Thermofight X: Worth It or Not?

We have to say no, it is not worth it. The evidence is just not there and its ingredient list is nothing special. Moreover, the company seems to rely on shady business practices and has horrible customer reviews. If you deal with them you will likely have to deal with bogus payments and unshipped products. Seriously, stay far away from this company and product.
