What is Thermofight X?

Thermofight X is a fat burner that boosts your metabolism and reduces your appetite to help you lose weight. The formula contains caffeine and jalapeno pepper extract to improve your fat-burning potential, and this is what some of the research has to say about these ingredients:

  • BMC Obesity – One trial published in this journal found that cayenne peppers may have fat-burning properties and reduce appetite in obese patients.
  • Nutrition Research – Green tea may reduce blood pressure and aid in weight loss.
  • International Journal of Obesity – Research suggests that the capsaicinoids in a jalapeno pepper boosts metabolism by 5%.

Who Makes Thermofight X?

Thermofight X is made by It Works!, a multi-level marketing company that sells weight-loss supplements, skincare products, beauty products, and vitamin supplements. Mark and Cindy Pentecost founded the billion-dollar company in 2001 when they released a controversial weight loss patch.

The Better Business Bureau has investigated the Florida-based company multiple times for unauthorized credit card charges. It Works! placed the blame on its Independent Distributors.

Independent Distributors pay the company a $99 fee for the rights to sell its products. They market the products to their friends and family to earn a commission. The company recently implemented new policies to prevent unauthorized credit card charges.

The Federal Trade Commission is also involved in an investigation pertaining to It Works!. The FCC claims the company is unlawfully misrepresenting how much income Independent Distributors can earn. The allegedly misleading claims were made in advertisements targeted towards individuals who lost employment because of COVID-19.

Thermofight X Claims

Thermofight X claims that this fat burner can help you lose 31 pounds in three months. The makers of Thermofight X also claim that this product supports “rapid ketone generation.”

The supplement is not a ketogenic weight-loss product. It does not contain any ingredients shown to increase blood ketone levels, so our researchers were confused as to why it’s being marketed as an exogenous ketone product.

Bottom Line

Bottom Line on Thermofight X Results

When it comes down to the science, some of the ingredients in Thermofight X may have some benefits, but no research exists to back up this specific combination. When you add negative reviews and potential side effects, we find it hard to determine if this is the best weight-loss solution.

Instead, a comprehensive weight-loss program individualized to each dieter’s needs may be the better option.

We’re excited about the features Noom – one of the best weight-loss apps on the market – has to offer.
