Burn XT Thermogenic Fat Burner Review
Everything You Need To Know

Using a thermogenic fat burner can speed up your weight loss by increasing the number of calories you can burn per day.

Burn XT is a weight loss supplement that makes some bold claims, but can it deliver?

Our Burn XT review will look more closely at what ingredients are found in each capsule, whether it is safe to use, and finally whether we would recommend this product or not.

What Is Burn XT?

Burn XT is a thermogenic fat burner made for both men and women that is manufactured by Jacked Factory.

It claims to burn fat whilst simultaneously helping to maintain muscle mass (see also ‘Bicep Exercises: Stretches and Routines To Strengthen Your Biceps‘).

Burn XT works by increasing your metabolic rate. This helps to burn extra calories.

If you are looking to lose weight and lower your body fat percentage, then it is essential that you are able to burn more calories (calories burned doing yoga) than you consume.


Ingredients Found In Burn XT

It is pleasing to see that Burn-XT Thermogenic Fat Burner has a label, with not only the ingredients used but also their dosages, too. Many of its competitors will avoid showing this information.

Often hiding behind terms such as “proprietary blend”.

When this term is used, the manufacturer is able to list the ingredients without going into detail about the dosages. The problem with this is that it is impossible to know if the ingredients available are potent enough to work their benefits.

Burn XT contains 5 main ingredients that include:

1 – Acetyl L-Carnitine (700 mg per serving)

The first ingredient found in this supplement is a naturally occurring amino acid. It is used to help transport the fatty acids into your cells, which are then burnt as energy.

There is research available that shows Acetyl L-Carnitine (see also ‘L-Carnitine: The Benefits And Side Effects‘) can help with sports performance, which is why it has become popular amongst athletes. Most famously by Olympian Mo Farah [1].

L-Carnitine has been shown to offer various benefits:

  • ​Improved recovery from exercise [2]
  • ​An increase in oxygen supply sent to your muscles [3]
  • ​Less fatigue [4]
  • ​Reduced muscle soreness [5]
  • ​Increased production of red blood cells [6]

2 – Green Tea Leaf Extract (450 mg)

Green tea leaf extract is proven to offer various weight loss and health benefits, this is due to it containing numerous nutrients and antioxidants.

One of the more powerful compounds found in green tea is epigallocatechin gallate or EGCG. This particular compound has been found to contain medicinal qualities [7].

Research has found that consuming green tea can increase fat oxidation [8], which is the process where fatty acids are broken down.

When the fatty tissue is broken down, it will subsequently be used for energy [9], then ultimately lead to weight loss.

​Green tea extract is also a source of caffeine, which is listed as a separate ingredient of this fat burner.

3 – Caffeine Anhydrous (270 mg)

Caffeine anhydrous is also present in Burn XT. It is a natural stimulant found in some of the most popular thermogenic fat burners (see also ‘Leanbean vs PhenQ: Which Fat Burner Is Right For You?‘) .

Stimulants like this are proven to boost your metabolism [10], which will result in extra calories being burnt, weight loss (see also ‘ The New and Updated Noom Food List of 2022 ‘), and a reduction in body fat, too.

This increase in your metabolism will also ensure you experience an energy boost and help you with your weight loss goals [11].

4 – Capsimax Cayenne Pepper Fruit Extract (50 mg)

Capsimax originates from cayenne pepper fruit extract, and it is this compound that gives peppers that spicy kick.

This ingredient causes a process called thermogenesis to occur within your body.

When this occurs your internal body temperature will increase, along with your metabolic rate.

Resulting in an increase in calories and fat being burnt [12]. Ultimately resulting in weight loss occurring.

Capsimax has also been shown to help relieve pain [13].

​5 – Bioperine Black Pepper (5 mg)

Bioperine originates from black pepper. This ingredient offers very little weight loss benefits. However, it has been shown to increase the bioavailability of other ingredients [14].

In simple terms, it ensures the other ingredients of the fat burner are absorbed efficiently. This makes them more effective at their own jobs.

Side Effects Of Burn XT

Jacked Factory Burn XT fat burner is made in a state of the art cGMP facility.

The company claims that the standard Burn supplement formula is one of the purest, safest, and made from the highest quality ingredients.

Taken at face value, you would be impressed when reading a statement like this, however, looking at the Burn XT ingredients, there is a real risk of encountering side effects.

The biggest issue with a thermogenic fat burner is its reliance on stimulants like caffeine.

​Caffeine is often found in fat burners and has proven benefits. It also has various issues that you should be made aware of. These side effects include:

  • ​Anxiety
  • ​Tremors
  • ​Headaches
  • ​Heart palpitations
  • ​Insomnia

Too much caffeine should be avoided, and if you are sensitive to this ingredient, then you really should be avoiding it.

The other ingredients found in Burn XT are not free of problems either.

L-Carnitine has been shown to cause issues such as diarrhea, nausea, stomach pain, and vomiting amongst others. Green tea has been shown to cause headaches, nervousness, sleep problems, vomiting, diarrhea, while capsicum may bleeding, a local burning sensation, skin irritation, coughing, and flushing.

Finally, Bioperine has been linked with skin rash, sleep disorders, confusion, appetite suppression, and depression.

Of course, not everyone will encounter these side effects. If you are not sensitive to any of these ingredients and stick to the recommended doses, you should be fine.

Burn XT Reviews

hand rating

Over 60% of Burn XT reviews on Amazon are positive, with statements such as:

 I liked how fast this worked! There’s a huge difference in the way that my clothes fit and just the side by side photos of a 6-day difference! I’ve learned to NEVER trust the scale cause I stayed the same weight but lost 2 inches on my waist (see also ‘The Best Waist Training Exercises You Can Do Anywhere‘) and 1 1/2 on my hips! This stuff is amazing! Can’t wait to order more!

​​– Sierra, Amazon buyer

I highly recommend it! It has only been a few days on Burn XT, and I have already dropped 4 pounds. My diet has not been on point, but I still have kept up with my workouts. I purchased this because I was looking for a fat burner to help make my workouts more efficient. I ended up choosing this one because it had a lot of great reviews, and I am glad I did!

​​– Kitty, Amazon Buyer

However, there are also some negative customer reviews with some worrying experiences:

I literally just started using it and I am not well. Profuse sweating, nausea, and I’m clamoring. Teeth are chattering. Am I able to return? This is the first day and I hate it already. I’d hate to lose $30.

​​​- Jo, Amazon buyer

I normally give a week to any pills that I’m taking. There’s no way I can give another day though this one. It tells you to start using one pill. I did. I took one in the morning as suggested. It’s made me extremely sick. It’s a sickness that I cannot easily describe. Extremely uncomfortable feeling. I felt so nauseated, dizzy. It is not an appetite suppressant. You just lose your appetite as you feel horrible. Since you feel nauseated after couple bites you feel like you want to throw up. I’m not sure if this is the appetite losing that someone wants to achieve. It makes you extremely uncomfortable. I think this product should be banned. I was driving from work to home and started driving the other way. It makes you so hard to concentrate and think clearly. I have had several different products before. This was the worst.

​​– DD Corpus, Amazon buyer

While some reviews look like users consider Burn XT as one of the best fat burners there is, there are also a few that were disappointed with this supplement.

How Do You Use Burn XT?

To use Burn XT, you will need to take 2 capsules in the morning with water as soon as you wake. After 5-6 hours pass you are allowed to take another 2 capsules.

Is Burn XT Dangerous?

Burn XT is not dangerous if you follow the instructions, and if you are not sensitive to caffeine, or any of its other ingredients.

Too much caffeine can cause numerous side effects so never exceed the stated dosage.

You should always check with your doctor before starting to use any new product or supplement (see also ‘What is Cardarine And is it Safe?‘).

​​Does Burn XT Make You Poop?

No, Burn-XT should not make you poop, or at least disturb your regular bowel movement in any way. You may experience some changes in your regular movement, but as long as you’re not allergic or reactive to any of its ingredients, then this product won’t make you poop.

​​Is There A Money Back Guarantee For Burn XT?

There is no money-back guarantee as such for Burn XT. Their Amazon listing states that they guarantee your satisfaction, stating the following:

We stand behind Burn-XT and guarantee your satisfaction. If for any reason at all you aren’t completely satisfied with your results from this fat-burner we will work to resolve your concern.

While this sounds like there is a guarantee, I am not entirely convinced. It would be better if the guarantee was written down so that we can see for ourselves what they mean by this statement.

Would We Recommend Burn XT?

Burn XT from Jacked Factory is a solid effort and using it will likely aid your weight loss and fat loss efforts.

Our review of this thermogenic fat burner (see also ‘NutraLeaf Fat Burner Review‘) shows that it contains an effective dose of various fat-burning ingredients to help you lose weight. Each one has been chosen to increase fat loss (peptides for fat loss) and provide you with an energy boost.

The problem with this product and other diet pills or fat burners (see also our review of PrimeShred) like this is that they rely too heavily on stimulants, which increases the risk of developing various issues.

Our suggestion would be to opt for an alternative, such as Leanbean if you are female, or PhenQ if you are male. Both dietary supplements contain ingredients proven to burn fat, but they also contain ingredients that can suppress appetite too. Something that Burn XT sadly misses.

Having ingredients that can suppress appetite will reduce food cravings, and ensure you lose weight as fewer calories are consumed.

We hope this review cleared out your questions about this product. And remember that your weight loss goal should be coupled with a healthy diet and regular exercise!
