Burn XT is a thermogenic fat burner manufactured in the USA by Jacked Factory. As with all the brand’s products, Burn XT is intended for athletically inclined individuals who spend a lot of time playing sports or working out in a gym.

As the name suggests, Burn XT is heavily geared towards supporting increases in fat loss. It also supports improvements in training capacity but its appetite-suppressing capabilities are unlikely to be as strong as those of dedicated weight management products.

When you are overweight and want to do something about it, hunger control is an important diet pill ability.

Typical Burn XT users want to get into shape and enhance fat loss to attain a leaner-looking, shredded physique.

Benefits of Jacked Factory Burn XT

The Jacked Factory website doesn’t make any claims for Burn XT. Instead, the approach is refreshingly honest. The site points out becoming lean isn’t as easy as taking a couple of pills or dietary supplements.

It goes on to say “Getting shredded doesn’t happen overnight” and emphasizes the importance of a healthy diet and exercise before stating Burn XT can amplify the results.

The Jacked Factory sales page at Amazon is more dramatic but not totally believable. It says BurnXT does the following things:

• Supports healthy metabolism and burns fat
• Suppress appetite
• Increases calorie expenditure and helps you lose weight
• Enhances focus and concentration
• Energy boost
• Improves mood
• Supports lean muscle mass

The good news is the ingredients the supplement provides have value in most of these areas. However, when supplement manufacturers talk about supporting lean muscle mass, they are referring to their supplements’ abilities to help improve fat burning without loss of muscle mass.

Several natural ingredients can do this but none of them are included in the Burn XT fat-burning formula.

How Does Burn XT Work for Fat Burning and Weight Loss

Burn XT provides three thermogenic fat burners. All of them have scientifically proven value. However, they are also three of the most commonly used diet pill ingredients in the world, so that’s hardly a claim to fame.

One of the thermogenic agents is caffeine. Although you may not be aware caffeine can accelerate fat loss, you will probably know about its abilities in other areas.

Caffeine is one of the most commonly used stimulants in the world. It’s good for boosting energy and for increasing mental focus. People often take advantage of these abilities by drinking cups of strong coffee or consuming energy drinks.

Thermogenic fat burners enhance a natural process called thermogenesis. It generates heat within the body. This boosts metabolism by causing the body to lose extra calories of energy in the form of heat.

When your diet is so low in calories it has caused your body to experience an energy shortage, the calories lost via thermogenesis will come from your stores of fat.

However, don’t expect Burn XT or any other thermogenic fat burner to work like magic. All any fat-burning supplement can do is help you to improve the results you are getting with diet and exercise.

By providing a slight increase in metabolism, thermogenic fat burners may also help you to overcome plateaus.

How to Use Burn XT Thermogenic Fat Burner

The standard dose is 2 capsules per day. However, Jacked Factory suggests new users begin with one capsule and maintain this dose during the first three days of use. Doing so makes it possible to monitor for tolerance issues. If there are any, the low dose also makes sure they will only be half as bad.

This type of approach is not unique to Burn XT. It’s common practice with pills that contain caffeine and/or other stimulants.

If side effects are not an issue, it’s possible to up the dose to 2 capsules, taken once or twice a day with meals. Four capsules per day is the maximum dose and should not be exceeded.

Jacked Factory also instructs Burn XT Fat Burner users to drink plenty of water throughout the day and avoid taking the capsules within 4 hours of bedtime.

Burn XT Fat Burner Ingredient Profile

Each Burn XT capsule provides 5 key ingredients in the following amounts:

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

Remember the above figures are per capsule, not per dose. When you use the standard dose, everything doubles.

How Burn XT Burns Body Fat and Helps You Lose Weight

Acetyl-L-Carnitine

Acetyl-L-carnitine provides the amino acid L-carnitine.

Research published in the Journal of Functional Morphology and Kinesiology (December 2021) shows that L-carnitine products can help improve physical strength, sports endurance, and exercise capacity. [1]

Many bodybuilding and sports supplements contain sources of L-carnitine because its value as a performance enhancer is so well known. Researchers have been studying its potential for decades.

Recent research suggests L-carnitine may also be able to influence mood for the better. In September 2021, Frontiers in Psychiatry published a paper that suggests L-carnitine supplements may be capable of helping manage depressive disorders. [2]

Green Tea Extract

Green tea leaf extract is one of the best natural thermogenic fat burners in the world and a very appropriate addition to the Burn XT thermogenic fat burning formulation.

As well as increasing metabolism, the antioxidants (green tea catechins), polyphenols, and caffeine in green tea have a proven ability to increase 24-hour energy and fat oxidation in humans.

However, although caffeine is a proven metabolism booster in its own right, the other green tea compounds appear to be mainly responsible for green tea’s ability to improve fat loss, reduce belly fat and help you lose weight. [3]

Caffeine Anhydrous

Caffeine helps support wakefulness and boosts energy by acting on the adenosine receptors in the brain.

Even without outside help, caffeine has almost 100% bioavailability when taken orally and its effects on the body can continue for 3 to 5 hours [4]

Data from numerous studies support using caffeine to increase metabolism and fat loss. The results of one clinical trial are particularly interesting because they indicate caffeine might be better for increasing fat oxidation in normal-weight individuals than in people who are obese. [5]

If this is so, there are strong arguments for using caffeine in fat loss products for people who are actively involved in bodybuilding or sports.

Capsimax (Cayenne Pepper Fruit Extract)

Capsimax is a branded ingredient that’s present in many supplement formulations that aim to burn fat.

The main ingredient is capsicum pepper extract. Although a lot of supplements provide standard capsicum extract, it can be hard on the stomach and may trigger heartburn and/or similar digestive issues.

Capsimax uses a special delivery technology that ensures the active compounds in the pepper are released into the gut instead of the stomach.

In addition to helping prevent gastric distress, this delayed release also aids ingredient absorption because nutrients, drugs, and other compounds the body ingests enter the blood by passing through the intestinal walls.

Capsicum’s ability to support fat loss is due to a particular compound. It’s called capsaicin.

Although capsaicin has a longstanding reputation as a thermogenic fat burner and, to a lesser extent, as an appetite suppressant, it also supports burning fat in additional ways.

One of the things capsaicin does is trigger brown adipose tissue (BAT).

Most of the body’s stores of fat are white adipose tissue (WAT). BAT is present in lesser amounts and is normally activated when low temperatures initiate increases in energy expenditure due to non-shivering thermogenesis.

Capsaicin also appears to decrease adipogenesis (the process that converts excess energy to fat) and regulate gene functions that relate to lipid metabolism (fat burning). [6]

Bioperine

Bioperine is a popular brand of black pepper extract. It’s a very common supplement ingredient that is standardized to be at least 95% piperine.

Piperine is an alkaloid. It’s responsible for giving pepper its distinctive smell. Black pepper extracts are commonly added to pills, capsules and medications because they improve the bioavailability of other ingredients. (7)

Real Burn XT Customer Reviews

Many customer reviews suggest Burn XT delivers acceptable results.

However, there are also plenty of reviews that have been left by people who say they noticed no benefits at all.

There are many reports of side effects as well but it’s important to be aware most Burn XT users do not appear to have to contend with any side effects at all.

A surprising amount of negative reviews are from people stating their bottles of Burn XT arrived open.

Not surprisingly, they did not risk taking the product so the reviews are based on their poor experiences, not on the supplement’s ability to perform.

Some Burn XT reviews from customers sharing positive experiences:

“Great fat burner, I have lost almost 8lbs in a month”

“The best fat burner I have ever used, my bathroom scales are loving this supplement’

“My before weight was 190 lbs and now I am 175 lbs – so with those before and after results I’d say Burn XT worked for me”

 Burn XT Reviews from customers complaining about a lack of results:

“Not lost any weight in months, may be a few pounds”

“Burn XT Thermogenic fat burner didn’t work for me”

 Burn XT Reviews from customers who say they received unsealed bottles of Burn-XT:

“I received my delivery but the bottle was not sealed?”

Potential Side Effects of Burn XT Thermogenic Fat Burner

Most of the Burn XT ingredients are unlikely to cause side effects. However, caffeine can cause jitters, nausea, anxiety, high blood pressure, and several other side effects.

People who are very sensitive to caffeine may experience such side effects in response to very low doses of caffeine. However, most people tolerate caffeine well and are unlikely to suffer side effects unless they consume the stimulant in high doses.

Burn XT provides 135 mg of caffeine per capsule. That’s 270 mg of caffeine per 2 capsules. Four (30 g) shots of espresso coffee only provide around 256 grams of caffeine, so that’s a lot.

Customers who take the maximum dose of 2 capsules 2 times per day will get the power of 4 espressos or more delivered with each dose. That’s too much caffeine to dump into the body at one time and 540 mg of caffeine per day is way too much.

FDA guidelines suggest healthy adults should not consume more than 400 mg of caffeine per day. [8]

That’s from all sources, including coffee and tea. Anyone who takes Burn XT alongside additional sources of caffeine will be even more likely to experience ill effects.

Due to the caffeine-rich nature of the Burn XT formulation, we suggest not using this supplement without checking with a doctor first.

Where to Buy Burn XT Fat Burner – Purchasing Options and Considerations

Burn XT is available to buy from several online sources including the manufacturer’s website and Amazon.

Each bottle of Burn XT provides 60 capsules. That’s a 30-day treatment when you are taking the standard dose of 2 capsules per day.

If you are taking the maximum dose, you will need to crack open a new bottle of Burn XT every couple of weeks.

Regardless of where you buy Burn XT, you can expect to pay around $35 per bottle (price correct at the time of this review).

Unfortunately, the shipping costs add to the price. Customers in the USA can get a 15% discount on recurring orders but only if they purchase Burn XT via subscribe and save.

Although subscribe and save arrangements can deliver enticing savings, many people choose to avoid them because they can be difficult to cancel.

In this case, the Terms and Conditions page suggests canceling should not be too difficult. However, it may be a good idea to only consider using Subscribe and Save if you have already had a good experience with Jacked Factory products and are sure you want to receive future shipments of Burn XT.

As with all Jacked Factory supplements, Burn XT does not have a money-back guarantee.

Burn XT Review Conclusion

Although Burn XT provides some of the best fat burners, capsicum is the only one that can help control appetite.

Most people who are overweight or obese will have greater success if they choose weight loss supplements that are capable of providing a superior level of appetite control.

Burn XT thermogenic fat burners should work better for bodybuilders and other individuals who are prepared to train hard. That’s who Jacked Factory is targeting, so no big surprise there.

However, most competing supplements that are aimed at this market contain ingredients that can help prevent loss of muscle mass due to calorie restriction. Burn XT fat burner does not.

The caffeine content is also an issue with this weight loss supplement. It’s too high. All things considered, unless you are used to high doses of caffeine and know you can handle them, you may want to choose an alternative fat-burning supplement instead of Burn XT.
