Burn XT Review – Thermogenic Fat Burner Weight Loss Capsules

So you’re looking for a weight loss supplement that burns fat, suppresses appetite and boosts energy? Burn XT is probably a name you’ve seen. Made by Jacked Factory this thermogenic fat burner is for men and women looking to lose weight and increase performance. With active ingredients like Acetyl-L-Carnitine and green tea extract it’s designed to burn fat not muscle.

Burn XT has sold over 30 million servings. But let’s get into the formula, effectiveness and downsides before you decide if it’s for you.

2025 Update. We’ll get into the good and bad of Burn XT, ingredients and compare to PhenQ—a fat burner many consider better. Does Burn XT deliver or disappoint?

SUMMARY
Burn XT is one of the most popular fat burning capsules sold though Amazon. This is sometimes a good thing and a bad thing.

In this case is more of a good thing that bad. Burn XT is a good product … but it failing is that it is not that strong. There are other fat burners that we consider to be far superior. PhenQ for example – a fat burner and fat blocker that pretty much sets bar.

What is Burn XT?

Burn XT is a supplement that’s primarily marketed on its alleged fat-burning capabilities. It’s produced in capsule format and the manufacturer claims the formulation is highly effective for men and women.

Data like this is hard to check, but the manufacturer also claims to have sold 30,000,000 servings to date.

That sounds like a lot but you’ve got to remember we’re talking servings, not bottles.

In this case, a serving is two capsules and there are 30 servings per bottle. If you do the math, what the manufacturer is really saying is it has sold 1,000,000 bottles.

It sounds a lot less when you think of it like that, but 1 million is still a lot of pills to sell. Again though, let’s not lose sight of the fact that this only the manufacturer’s claim.

I don’t mean to be overly pessimistic, but Burn XT is primarily sold via Amazon and, at the time of this review, Amazon.com was showing less than 15,000 ratings. It’s not even marked as an Amazon bestseller.

However, Burn XT is a vegetarian-friendly fat-burner that contains some respected ingredients.

The other thing you need to know is, the formulation contains quite a lot of caffeine. In fact, it may be more than some people can stand.

Each dose contains nearly as much caffeine as three cups of coffee. When you know that it may not surprise you to learn there are lots of reports of side effects.

Having said that, If you are confirmed caffeine junkie, Burn XT probably won’t cause you to break a sweat. Let’s take a closer look at this fat burner and see what it can do.

Who Makes Burn XT?

Burn XT is part of a range of health and fitness supplements distributed by Jacked Factory. It’s hard to find any information about the company.

The Jacked Factory website has an “About US” page, but it doesn’t provide any information about who founded the company, where it is based, or what experience it has in the supplement industry.

All the page does is provide a few promises about quality and pricing, stating the company aims to provide top-quality supplements at reasonable prices.

The site has no mailing address and I cannot find “Jacked Factory” or “Jacked Factory Corporation”, listed on the Better Business Bureau (BBB) website or anywhere else online.

If you look at the label on a bottle of Burn XT you will find a partial Canadian mailing address (St. Johns, NL, A1A5A1).

St Johns is an area in Newfoundland and Labrador. At least two streets share that postcode and they both have several hundred buildings on them.

The interesting thing is, the label states Burn XT is manufactured for Jacked Factory, not by Jacked Factory. That could suggest the company may be buying white-label products and selling them on.

Trying to find out information about this company is like taking a swim in very murky water. However, I have not been able to find any scam warnings or similar complaints. That suggests Burn XT probably conducts its business in a reputable way.

What are the Burn XT Benefits?

Burn XT is primarily intended to function as a fat burner. However, the marketing bias is more towards bodybuilders and athletes so the formulation also aims to protect existing muscle mass.

The additional promised benefits include:

• Boosts energy
• Suppresses appetite
• Increases metabolism
• Helps you to burn more calories
• Accelerates fat loss
• Improves the mood

What are the Ingredients In Burn XT?

Burn XT contains five active ingredients. Each (2-capsule) serving provides:

• Acetyl-L-Carnitine  (700mg)
• Green Tea Extract (450mg)
• Caffeine Anhydrous (270mg)
• Capsimax (50mg)
• Bioperine (5 mg)

What Do the Ingredients Do?

A cutting-edge formulation? Jacked Factory says so but I don’t agree. All the ingredients are diet pill regulars. However, there’s a reason for that and it’s a simple one—all of them have abilities that can support the aims of a formulation such as this.

Jacked Factory provides the inclusion rates as well. That’s great. A lot of companies fail to do this. At least Jacked Factory is allowing its customers to know exactly what they will be putting into their bodies every time they knock-back a couple of Burn XT capsules.

So far so good. Now let’s take a look t the five ingredients one by one.

1. Acetyl-L-Carnitine

Acetyl-L-Carnitine is an amino acid. It’s a popular ingredient with sport’s supplement manufacturers because it can boost training capabilities by drawing extra energy into the cells.

You can also find this ingredient in bodybuilding supplements because it helps you to recover faster after training and reduces the likelihood of muscle degradation.

2. Green Tea Extract

Green tea is one of the best natural fat-burning ingredients available. It’s also often said to be one of the healthiest beverages in the world.

The fat-burning reputation of green tea is not built on hearsay. It’s based on cold, hard facts. Green tea’s ability to speed weight loss is supported by an impressive amount of clinical research.

Furthermore, the results of one study suggest green tea speeds up energy expenditure and fat oxidation for up to 24 hours.

3. Caffeine Anhydrous

Caffeine is the most socially-accepted stimulant in the world. Some people fend off fatigue by taking caffeine pills and lots of people use it for boosting energy. It’s a key ingredient in most energy drinks.

Research shows caffeine encourages fat burning by boosting metabolism and thermogenesis. The bottom line is, it’s a fat burner that works.

There are lots of way of getting caffeine into the body and caffeine anhydrous delivers it fast. That’s especially worrying in this case because Burn XT provides such a high dose.

4. Capsimax

Capsimax is a patented ingredient. As the name suggests, it provides capsicum extract. Capsimax is also the best capsicum extract you can get. Thanks to a special bead technology, it’s easier on the stomach than standard extracts are.

Like caffeine, capsicum works by speeding metabolism and increasing thermogenesis. Research supports its use in this role. Studies show capsicum can further support weight loss by suppressing hunger as well.

5. Bioperine

Bioperine is a respected brand of black pepper extract. It’s not just a diet pill ingredient. You can find Bioperine is supplements of all kinds.

Black pepper provides piperine. It’s the alkaloid that gives it such a distinctive taste and smell. Piperine also has another, more useful ability. Manufacturers put piperine in supplements because it helps your body to absorb the other ingredients more easily.

How Do I Use Burn XT?

You take two capsules first thing each morning and wash them down with water.

Users also have the option of taking two more capsules five to six hours later. Bearing in mind the high caffeine content this may not be a good idea and you certainly won’t want to take them within five hours of your bedtime. Caffeine can interfere with sleep.

If you want to take two doses per day, Jacked Factory says you should refrain from doing so for the first couple of days. This will allow you time to see if any negative issues occur.

Jacked Factory also stresses the importance of using the capsules alongside diet and exercise. The company further suggests you keep using the pills for at least 60 days.

The other thing to know is you will need to ensure you are drinking plenty of water throughout the day. This will help you avoid the risk of dehydration.

Are There Any Burn XT Customer Reviews?

There are a lot of Amazon customer reviews.

The majority of the reviewers award the product four or five stars. That’s good to see. However, I’m seeing some comments like, “Just started so I can’t review”. That may suggest Jacked Factory is pestering customers to leave reviews.

Certainly, many of the positive reviews are unusually long (for Amazon) and I’m seeing more customers providing photos than is normally the case. That makes me wonder if the reviews might be incentivised in some way.

The other thing I see is a lot of reviews left by people who have only been taking the pills for a few days to a couple of weeks. I see that as a first impression, not a reliable review.

Again, I have to ask myself why people are in such a rush to provide their reviews. I’d wait until I’d finished the full bottle, wouldn’t you?

Does Burn XT Have Any Known Side Effects?

Many customers say the pills made them unwell.

A few commonly-reported Burn XT side effects include:

• Nausea
• Anxiety
• Sweating
• Shaking
• Bloating
• Headaches

Most of the side effects customers report are typical of what you’d expect if you overdid it with caffeine. No surprise there. However, some customers share some very scary tales.

If you are considering using Burn XT I strongly recommend getting some expert medical advice first. In fact, if you take the time to read the warning on the bottle, you’ll see Jacked Factory tells you the same thing.

Where Can I Buy Burn XT and How Much Does It Cost?

If you want to buy Burn XT, you have two choices. The first option is to buy it via Amazon. The second one is to order it from the Jacked Factory website. Either way, you’ll end up paying the same.

A bottle of Burn XT costs just under USD 30. Shipping is extra, but this is still a cheap fat-burner to buy. At least it is if you are only taking one dose per day. Do that and your bottle will be good for 30 days.

If you opt to take two doses per day (not advised), you’ll be going through a bottle of Burn XT every two weeks. That would bring the cost of using the product up USD 60 per month. That’s around the same as you’d pay for any of the top-rated weight loss products.

Does Burn XT Have a Guarantee?

Jacked Factory is offering a 30-day money-back guarantee. That’s not long and Burn XT deduct shipping costs from the refund along with an undisclosed handling fee.

Will Burn XT Help Me to Lose Weight?

Burn XT contains green tea and caffeine. Both ingredients have proven fat burning capabilities. Personally, I’d have liked to see a lot more green tea and a lot less caffeine.

As I already mentioned earlier in this review, Burn XT contains almost as much caffeine as you’d get from three cups of coffee. However, it would take you some time to drink three cups of coffee. The caffeine in Burn XT will hit your system a lot faster. This can only increase the likelihood of side effects.

There another problem with diet pills that are overly reliant on caffeine. The effects diminish with use. So, although, you may find the results are good during the early stages, you are likely to see them begin dwindling over time.

If you are just a looking for a diet pill to help you to lose weight, Burn XT is not the best option to choose. However, if you are a hard training athlete, all that caffeine may give you extra energy and help you to train harder but side effects could still be an issue.

Many athletic individuals are used to caffeine-rich supplements though. They often build up a tolerance if they’ve been using such products for a long time. If this is true for you, side effects may not be an issue.

Unfortunately, we still come back to the same problem—the benefits of caffeine decline over time.

After reading this review, you have all the information about Burn XT, good and bad. That puts you in a position to make up your own mind. Do you want to take a gamble on a caffeine powered product like this or would you prefer to go with something else?

Recommended Fat Burner

As mention at the start of this Burn XT review – PhenQ is a capsule based fat burner that is formulated to just about right.

It of course does has it floors – such as the pretty bland bottle – but as a product it does what it says on the tin.

It is suitable for male and female dieters and has a good safety record.
