Dietary supplements that aim to help with weight loss have become increasingly common, and the Burn XT fat burner is one that we have seen advertised a lot.

Over the years, we have tested over 50 of these supplements, and in most cases, they fall way short of the mark.

So, our team got together with a few clients to go through our usual supplement testing routine.

And in this Burn XT review, we’ll give you a load of details about what's actually in it, the science behind it, and whether we would recommend it.

What is Burn XT?

Burn XT

Burn XT is a weight loss supplement that is part of the fat burners category. That means that it’s based on a formula that uses natural ingredients to increase fat loss.

It also claims to suppress appetite and hunger cravings by making you feel full for longer.

Made by a company called Jacked Factory, the supplement should also result in an energy boost from releasing those fat reserves. The company is known for a range of Burn supplements.

Those are great claims to make, but do they actually live up to the scrutiny of a dietitian? Let’s have a closer look at the Burn-XT thermogenic fat burner ingredients.

Burn XT Ingredients

unique ingredients

We got together with a dietitian to take a closer look at not only the ingredients but the dosage as well. We’ve seen it too often that the per day recommended dose is just too weak to properly trigger fat burning and appetite suppression.

Let’s see what she found out.

1 - Green Tea Extract (450mg)

Green Tea Extract

Believe it or not, but green tea leaf extract is actually one of the best known fat-burning ingredients available.

Most people just think of it as a good source of antioxidants. But there’s way more to it.

Our dietitian pointed us to quite an extensive study that had noted positive effects on weight loss from green tea leaf extract [1].

And the dose of 450mg per day seems to be good enough to trigger thermogenesis.

2 - Caffeine Anhydrous (270mg)

Caffeine anhydrous is also a well known thermogenic fat burner.

Yes, that means that your morning coffee could actually be helping you burn off some of that stubborn belly fat.

Now, I would point out that the average cup of coffee has about 100mg of caffeine. That means that Burn XT could be giving you two and a half times as much per serving.

While it could increase fat loss, it might be a bit much for a lot of folks.

More on the possible side effects later.

3 - Capsimax Cayenne Pepper Fruit Extract (50mg)

Cayenne Pepper Seeds

The cayenne pepper fruit extract has been extensively tested, and one recent study was able to establish an increased fat loss in men and women [2].

The same study also commented it seemed to suppress appetite as well.

However, you should note that the study applied a 2.5 mg dose of the active ingredient called capsaicin.

But Burn XT would only provide about half that amount.

A study published in PloS One found that consuming cayenne pepper for breakfast creates less appetite, so people eat fewer calories during the day.

4 - Acetyl L-Carnitine (700mg)

Jacked Factory claims it contains an effective dose of acetyl l-carnitine, which I was aware of as an ingredient in recovery shakes.

But it does seem like there would be some evidence that it also plays a role in fat oxidation [3]. Whether it is the most effective to get rid of body fat is still being debated in the nutrition science community.

5 - Bioperine Black Pepper Fruit Extract (5mg)

This doesn’t directly burn fat, but instead, it has been shown to help nutrient absorption. It could essentially contribute to getting the other weight loss ingredients into your body faster [4].

It could even help with the digestion of your regular meals as well.

Spreading Out Your Intake

Make sure you spread out the two capsules, especially when you’re getting started. This would allow you to assess how your body reacts to fat burners.

Also, keep in mind that you may want to take the Burn supplement capsules just before a meal. I would suggest before breakfast and lunch and avoid taking it later on in the day.

This is because the regular dose contains a lot of caffeine that could affect your sleep.

I also have a few clients who like to take diet pills before they start their regular exercise routine. It seems like the mental energy boost from caffeine helps with training motivation.

Pros and Cons

Burn XT

OK, let’s start the positives. This thermogenic fat burner does seem to contain the right ingredients to help with weight loss.

A lot of online reviews highlighted that they were able to drop a fair bit of abdominal fat.

There are also positive reports about increased energy levels, which in part is probably due to the high dose of stimulants.

But for some people, this might be too high a boost that could lead to jitters and sleepless nights.

And the last thing we noted during our testing is that taking this product in the morning didn’t seem to suppress our appetite enough to extend fasting periods.


I also think that Jacked Factory could change the dosage a bit. You’re recommended to take one capsule in the morning and one at lunchtime.

However, if women wanted to take a smaller dose, then that would be impossible.

Check out our article on the supplements that will get you shredded.

  • Claims to provide physical and mental energy
  • Seems to work well for fat burning
  • Contains no fillers or additives to mess up your diet
  • Has a very high dose of stimulants
  • The product doesn’t seem to help with hunger cravings
  • The daily dose is limited to two capsules

Side effects

side effects

Negative health impacts are always a risk, even when the supplement ingredients are completely natural.

There are two common side effects that we noted with this Jacked Factory product.

First of all, some people seemed to get some cramping after taking the capsule on an empty stomach.

This may be linked to some intolerance or allergy, so be careful with your timing.

The second issue is the rather high dose of caffeine. It’s not a major health issue, but you certainly have to avoid taking it later in the day if you want to avoid staring at the ceiling all night.

Where Should You Buy It?

I pretty much always send my clients to Amazon or the official company website. It might be the best option if you’re signed up to Amazon Prime for same or next day delivery.

But the important thing to avoid is places like eBay or other marketplaces where you might increase your risk of a counterfeit product.

In the supplement industry, this has unfortunately become quite common, and you could expose yourself to health risks if you start taking dodgy supplements.

User Reviews

hands on phone

To give you a bit more perspective on what other people are saying, we took a look at Burn XT reviews on Amazon as well as some forums and Facebook groups.

The biggest problem she initially had was with a high dose of caffeine. It did help her with weight loss, but she ended up switching to caffeine-free supplements instead.


- Letitia from Houston

Karen experienced 20 pounds of fat loss in 2 months and found an increase in energy for physical and mental activities to be quite helpful as well.


- Karen from Boston

He had mixed results. It did seem to trigger weight loss effects, but after a few weeks, the cramping didn’t settle down, so he had to stop taking this supplement.


- Charlie from Vancouver

Rob seems to be a bodybuilder, and he wasn’t specifically trying to lose weight. But during a cutting phase to get more ripped, he did report some positive effects from the ingredients.


- Rob from London


Is Burn Xt Safe?

Yes, Burn XT is considered to be safe, as all the ingredients are classified as generally safe. However, there is always a chance of negative effects when you take a diet supplement, so take a smaller dose of the product when starting out.

Does Burn Xt Make You Poop?

No, Burn XT doesn’t make you poop. The ingredients included may support your digestive system by absorbing nutrients faster. But the product is not known for making you poop more as a result.

Is Burn Xt Thermogenic?

Yes, Burn XT is a thermogenic fat burner, and there are quite a few positive reviews about this. With ingredients like green tea and caffeine, it has been proven to be effective at boosting your metabolism to help you lose weight.

How do you use Burn XT?

You use Burn XT by taking two pills during the day. One should be taken first thing in the morning with breakfast and the second at around lunchtime. It’s best to avoid them later in the day as the stimulants could impact your sleep quality.

Is Burn XT The Right Investment To Make?

So, we do believe that this product works well as a thermogenic fat burner. However, because there were quite a few reviews about side effects, we were a bit concerned.

It also seems to be lacking a bit when it comes to suppressing hunger cravings.

What we would actually recommend is PhenQ, as I've seen it drive the most significant effects on weight loss for my clients. Users have reported it helped them achieve a healthy lifestyle by burning more calories and extending fasting periods.

It also works to replenish electrolytes so it's a good option when you're doing some intensive fat burning workouts.
