Burn XT Review

BURN XT is a thermogenic fat burner manufactured and distributed by Jacked Factory. It’s mainly marketed online, especially via Amazon, where it’s a popular choice with customers seeking weight management support.

As is often the case with Amazon diet pills, the benefits Burn XT provides appear to come with a few caveats.


Contains some good ingredients.
Respected manufacturer.
Competitively priced.
Good guarantee period.


Too many stimulants.
No heavy duty fat burning ingredients.
No B-Vitamins.

Burn XT ranks as one of the top-selling fat-burning capsules on Amazon, which carries both advantages and disadvantages. However, in this instance, the positives outweigh the negatives.

Burn XT is a commendable product, but its main drawback is that it isn’t particularly potent. Compared to other products on the market, there are superior options available. For example, PhenQ stands out as a fat burner, appetite suppressant and fat blocker, effectively setting the standard in the industry.

In this Burn XT review, I will take a look at the supplement’s efficacy along with its ability to provide value for money. My objective is to provide a thorough analysis based on scientific evidence supporting the abilities of the ingredients.

I will also take a look at customer feedback and use it to determine whether Burn XT lives up to the claims Jacked Factory makes for the supplement and establish its potential to provide a safe user experience.

Product Description: What Is Burn XT?

Burn XT is a thermogenic fat burner supplement that contains natural ingredients. Supplements of this type provide compounds that cause a slight increase in body temperature, increasing metabolism, and calorie expenditure.

Burn XT real reviews

As with most alternative fat-burning supplements, Burn XT also boosts energy and mental focus but, although it may help a little with hunger and cravings, it’s only likely to have modest value as an appetite suppressant

This is one of the main limiting factors of this supplement. People become overweight when they consume more calories than their bodies need, more often than not by eating too regularly or consuming overly large portions at mealtimes. Any attempt to adopt better eating habits often results in an unpleasant battle against hunger.

It’s easier to give in to hunger than to fight it. Fat burners like Burn XT offer little or no benefit to people who are unable to maintain the calorie deficit state that necessitates the need for fat burning.

However, although Burn XT has some failings, the marketing claims are not one of them. Jacked Factory makes it clear that relying on the abilities of the pills alone is not good enough, pointing out that the supplement will not help anyone to get “shredded” overnight and that results won’t be forthcoming without adhering to appropriate diet and training protocols.

This type of honest approach is refreshing. These days, most of the other diet pills I encounter are marketed with claims that are very deceptive and misleading.

Who Can Use Burn XT?

Burn XT for adult men and women who are already following a structured diet and exercise plan. However, because of the limitations that I have already discussed, it’s a poor choice for anyone who has difficulty controlling their hunger.

Burn XT for men and women

Due to the choice of ingredients, Burn XT offers the most benefit to bodybuilders and people who actively participate in sporting or athletic pursuits. The formula’s ability to boost energy and focus can enhance athletic ability and endurance, helping to support more productive training sessions.

However, If you have any pre-existing health conditions or would need to use Burn XT alongside medication, I strongly suggest you seek guidance from a healthcare professional before commencing supplementation. It’s a sensible precaution that will help ensure the supplement aligns with your present health status,  treatment protocol,  and personal fitness goals.

Mechanism of Action – How Does the Fat Burner Work?

Thermogenesis is a metabolic process where your body burns calories to produce heat. Burn XT enhances it encouraging faster metabolism and, potentially, more rapid fat loss.

Supplements that increase thermogenesis facilitate higher calorie expenditure throughout the day—even when you are resting.

Burn XT also contains energy-boosting ingredients that help combat dietary fatigue—that tired feeling that is so common among people who are cutting back on their calories.

By increasing energy, Burn XT also supports better workouts. With more energy, you can push harder and perform better during exercise.

Manufacturer Credibility

Jacked Factor is a reputable company that produces an impressive range of supplements, all of which are primarily aimed at bodybuilders and people with similarly athletic lifestyles. The company has a strong commitment to using research-backed ingredients and steering clear of unnecessary binders and fillers that may dilute the effectiveness of its products. 

Jacked Factory always adheres to transparent labeling practices. It discloses all the ingredients present in its supplements along with the doses. This is something that impresses me.

A lot of supplement companies house some or all of their ingredients in proprietary blends. This is a practice that makes it difficult to judge the potency of their products and the potential side effects they may present because, although you know what the ingredients are, there is no way to know the quantities present. 

This level of transparency extends to the company’s marketing strategies as well. It maintains an honest approach, avoiding exaggerated claims about the benefits of its products. This straightforwardness is refreshing in an industry where outlandish claims and clever marketing hype are such common practice.

Jacked Factory also makes it easy for existing and potential customers to contact its customer service representatives via telephone,  email, or live chat.

However, the company currently does not provide its customers with money-back guarantees. All the industry leaders back their products with money-back guarantees that last for at least 60 days. By not doing the same, Jacked Factory could cause potential new customers to doubt the quality of its products.

Burn XT Ingredient Profile

Each Burn XT capsule contains five key ingredients:

  • Acetyl L-Carnitine HCI (350 mg)
  • Green Tea Extract (225 mg)
  • Caffeine Anhydrous (135 mg)
  • Capsimax (25 mg)
  • Bioperine( 2.5 mg)

The first four ingredients directly contribute to the supplement’s ability to support improvements in energy levels and fat burning. Bioperine is a helper ingredient that’s present to enhance their absorption helping to increase the benefits.

The Burn XT formula is very clean. It’s devoid of unnecessary binders and fillers and the use of a hypomellose coating on the capsule allows Burn XT to be a suitable choice for vegans and vegetarians.

Burn XT Ingredient Analysis

All four of the main Burn XT ingredients have clinically proven fat-burning capabilities. Two of them, have good credentials as energy enhancers too.

In this section, I will explain the benefits each ingredient brings to the table while trying not to be overly technical or blind you with science. If you are keen to take a look at the clinical data about any of the ingredients, you can do so by following the study links I have included in the research sources at the bottom of the page.

Acetyl L-Carnitine HCI (350 mg)

Acetyl L-carnitine (ALCAR) is a natural compound derived from the amino acid L-carnitine. Jacked Factory is using a hydrochloride (HCI) salt form of the ingredient. The addition of HCI helps increase ALCAR’s stability and bioavailability.

ALCAR is a common addition to weight loss and performance supplements because L-carnitine plays an important role in how the body handles fat and energy. The main thing it does is help transport fatty acids into the mitochondria (the powerhouse of the cells) and burn them to produce energy.

Adding ALCAR to a supplement like Burn XT enhances this fat-to-energy conversion process. This means that with regular exercise and a proper diet, people using the supplement may notice improvements in endurance. They should also be able to reduce their fat mass more effectively than would be possible with dieting and exercising alone.

ALCAR has benefits beyond just fat burning. It’s also known for its potential to boost brain function. The calorie-restricted state that’s necessary to force the body to burn fat often causes mental fog. The cognitive support ALCAR provides may help Burn XT users remain mentally sharp and well-focused.

Green Tea Extract (225 mg)

Green tea extract is a key component in many weight loss supplements, and for good reason. It’s derived from the Camellia sinensis leaves and is highly valued for its high concentration of catechins, particularly epigallocatechin gallate (EGCG), which is known for its potent fat-burning properties.

The EGCG in green tea helps to boost the body’s metabolic rate by increasing thermogenesis. A wealth of data from clinical trials is highly supportive of using green tea beverages and extracts to support more efficient weight loss.

The antioxidants tea provides also help reduce oxidative stress within the body, which not only supports overall health but can also improve workout recovery times.

By reducing the damage that intense physical activity can cause at a cellular level, green tea extract helps the body recover more quickly between workouts.

Caffeine Anhydrous (135 mg)

Caffeine Anhydrous is a highly concentrated form of caffeine that can have a potent effect on energy levels and metabolism. It’s a popular ingredient that’s present in many weight loss and pre-workout supplements.

Caffeine is a central nervous system stimulant that’s useful for sharpening mental focus, fighting fatigue, and increasing energy levels. Because it’s more concentrated and easy to absorb, the anhydrous form of caffeine gets to work fast. Many people notice the benefits within 20 minutes of consuming it but results can vary from person to person.

Nevertheless,  because Burn XT proivdes a decent dose of caffeine in a concentrated form, many people using the supplement may notice improvements in alertness and a greater ability to concentrate on things they are doing. This can be a significant advantage both during workouts and daily activities.

The energizing effects of caffeine anhydrous can help in both these areas as well by combating the sluggishness that’s a common response to calorie-restricted dieting.

Data from many studies show caffeine has much to offer as a thermogenic fat burner and Burn XT provides it in a dose that’s sufficient to work well. However, the body can adapt to caffeine, causing it to become less effective.

Capsimax (25 mg)

Capsimax is an innovative ingredient that harnesses the thermogenic and appetite-suppressing powers of capsaicin—the compound found in chili peppers that gives them their heat. 

Capsaicin’s abilities as a thermogenic fat burner have allowed capsicum extract to become one of the most commonly used ingredients in weight management supplements. It also has reasonable value as an appetite suppressant. Unfortunately, Burn XT lacks ingredients that can support it in this role so the supplement’s ability to control hunger will be modest at best.

One of the most important features of Capsimax is its unique delivery method. Unlike raw capsaicin, which can be harsh on the stomach and cause discomfort, Capsimax is designed to house the capsaicin molecules inside a special coating that delays its release.

It’s a gentle yet powerful option that makes it possible for people who are sensitive to spicy foods to benefit from the metabolism-boosting effects of capsaicin. By releasing the compound inside the gut instead of the stomach, this special delivery technology also supports optimum absorption.

Besides its effects on metabolism and appetite, Capsimax also plays a role in energy production. By stimulating thermogenesis, it helps maintain a steady energy level, which can be particularly beneficial during workouts.

Bioperine( 2.5 mg)

Bioperine is a patented extract derived from black pepper. It’s specifically designed to enhance the absorption of supplement ingredients.

Its inclusion in the Burn XT  formula will significantly boost the effectiveness of the other ingredients by ensuring their easy passage into the bloodstream.

The thing that sets Bioperine apart from standard black pepper extracts is its potency. It’s standardized to always provide a high concentration of piperine—the active compound in black pepper.

Normal black pepper extracts are generally less than 10% piperine. Bioperine is always at least 95% piperine.

Dosage and Potency Evaluation

Jacked Factory makes it clear that people who are sensitive to caffeine should not use Burn XT. It also suggests new users begin by taking only one capsule per day. The standard dose is two capsules per day but Jacked Factory suggests starting with an initially lower dose to provide the opportunity to monitor for side effects and test product suitability.

If no adverse issues become apparent, it’s possible to increase the dose to two capsules per day from the second week onward.

During the first week, the capsules are taken in the morning with water and a meal. After that, the dose is one capsule, two times per day, with water and a meal.

Jacked factory suggests at least 8 oz of water to wash down each dose, along with an overall increase in daily water consumption to prevent dehydration and support overall good health.

Each capsule provides 135 mg of caffeine. That’s close to what you would get from a double espresso coffee. The dose is not overly high but will be too much for anyone who is caffeine-sensitive.

When users progress to the full dose of two capsules, the dose will be 270 mg via two installments. That’s unlikely to cause problems for most men because there will be several hours between doses.

Women will need to tread more carefully. The female endocrine system is more sensitive to caffeine. High doses have been shown to cause hormone disruptions. Because of this, it may be best for women to continue taking only one pill per day. However, doing so will lower the potential benefits all around by restricting the other ingredient doses.

Safety and Side Effects

The capsaicin that makes capsicum extract so useful as an ingredient in fat-burning supplements has the potential to cause heartburn and other symptoms of gastric distress. Especially for people with sensitive stomachs. However, Burn XT doesn’t use a standard capsicum extract. It uses Capsimax, so this type of response is unlikely.

Negative reactions are rare, but Acetyl L-carnitine has the potential to upset the stomach and cause nausea or vomiting. Headaches are another possible side effect of ALCAR.

Supplements that provide caffeine can cause a variety of side effects including jitters, nausea, and rapid heartbeat. However, reactions such as these only occur in people who are unusually sensitive to its effects or those using supplements that contain caffeine in overly high doses.

Even people taking two Burn XT capsules per day are unlikely to have to contend with caffeine-related issues unless they are sensitive to it or using the supplement alongside other sources of caffeine such as tea, coffee, energy drinks, or additional supplements.

However, as I pointed out earlier, due to the way the female endocrine system responds to caffeine, for the average woman, taking two Burn XT capsules per day may not be a smart move.

Burn XT Customer Reviews and Consumer Insights

 Burn XT reviews from customers present a diverse range of experiences. The feedback and customer reviews available makes it clear that the effectiveness of this supplement can vary significantly among users, with reviews almost evenly split between positive and negative.

negatives reviews on Burn XT

Users sharing positive experiences often note significant improvements in their energy levels and weight loss results, with some of them saying the supplement helps them feel more active throughout the day.

On the other hand, there’s a substantial number of users who say they feel the supplement let them down, often reporting zero benefits and questioning the overall efficacy of the supplement.

Some of the people sharing negative experiences share details and concerns about side effects, typically jitteriness, upset stomach, or difficulty sleeping.

Responses such as these suggest a high dose of caffeine so I was not surprised to notice these side effects are predominantly reported by female users of Burn XT. Given the severity of some of the reactions, I also have to wonder if the people reporting them were consuming caffeine from additional sources, other than Burn XT.

However, one review states two capsules provide 700 mg of caffeine. This is not the case, which makes me question if the supplement in question may not have been a counterfeit product.

Fake supplements often make their way onto online marketplaces like Amazon and eBay. That’s why it’s generally best to purchase supplements directly from their manufacturer’s websites and avoid options that are only available from third-party sources.

Burn XT Usage Costs and Ability to Provide Good Value for Money

Burn XT is predominantly distributed via Amazon. It’s available in bottles that provide 60 capsules and in bottles that contain 120 capsules. Depending on which option you choose, you can expect to pay between $35 and $55 per bottle and modest discounts are available to people who order via subscribe and save.

When you are taking Burn XT thermogenic fat burner at the standard two-capsule dose, depending on the bottle size, the usage cost will be $25.50 to $35 per month. This will halve for those only taking one capsule per day. Either way, Burn XT is not an overly expensive fat burner to use.

However, Burn XT is very limited in what it can do. As I pointed out earlier in this review, the supplement’s limited ability to suppress appetite is a problem because most overweight people find it very difficult to cut back on food.

People who buy Burn XT and find they need extra help to control their hunger may need to buy additional supplements. This will involve additional expense and will require careful supplement selection to avoid unfavorable ingredient reactions.

Those who stick with Burn XT, use it alone, and fail to address their hunger issues may experience weight gain instead of weight loss, making Burn XT a very poor investment.

However, bodybuilders who are cutting may find Burn XT a more appropriate choice. They may be less susceptible to hunger and will probably only need to use the supplement to refine their physiques and improve their overall body composition. In this instance, Burn XT could provide better value for money but it lacks the refinement of alternative options that can also help prevent loss of lean muscle mass.

Burn XT Rating

Rating: 6/10

Jacked Factory Burn XT Review Conclusion

People looking for fat burner supplements have plenty of options available to them. Burn XT is one of them. It’s one of the most popular dietary supplements on Amazon.

However, although Burn XT is manufactured by a reputable company that discloses the supplement’s full formula and uses honest marketing tactics, Burn XT has several failings that interfere with its ability to provide customers with good value for money. This is compounded by the fact that the supplement lacks a money-back guarantee.

Thermogenic fat burner supplements are popular with a wide range of people, most notably bodybuilders and people who want to lose weight.

Bodybuilders may find Burn XT attractive because, in addition to boosting metabolism to help the body reduce its fat stores, the supplement can deliver a notable energy boost, especially when taking the recommended dosage of two capsules per day. Those who wish to do so could throw all this extra energy into intense workouts.

Unfortunately, most of the supplement’s ability to provide an energy boost is due to caffeine, which can become less effective as the body adapts to its presence. In this respect, it does not compare well to many alternative options, which may cost a little more to buy but have superior formulas that do not have such a great reliance on caffeine to boost energy. Some of these formulas, also help prevent loss of muscle mass when the body is experiencing a calorie deficit.

Thanks to the inclusion of Capsimax and green tea extract, as a fat-burning supplement, Burn XT’s credentials are first-rate. It has the potential to benefit athletes and people who want to lose weight.

Unfortunately, as a weight loss supplement, Burn XT’s inability to control hunger hinders its value. It certainly has the potential to help people burn body fat faster and reduce their body weight, but their weight-loss efforts could be made miserable by uncontrolled food cravings.

So, although Burn XT has science-backed credentials as a thermogenic fat burner, it leaves a lot to be desired in other areas.
