This thermogenic weight loss formula gets the job done with minimal side effects. The product combines several powerful ingredients that are very effective in ramping up metabolic processes. You also derive extra benefits that make your life more enjoyable. Hardcore Fat Burner promotes weight loss and gives you more energy. It’s a round-the-clock fat burner made of 11 science-backed ingredients.

Moreover, this supplement is vegetarian- and vegan-friendly and highly potent. But don’t just take our word for it. Let’s have a closer look at the ingredients of this top-rated thermogenic supplement. For one, its 500mg of green tea extract is just enough to lower your triglyceride levels (a type of fat), accelerate metabolic actions, and energize fat-burning hormones like norepinephrine.

Similarly, 250mg of L-theanine packs plenty of steam when it comes to reducing carbohydrates and fats (both of which contribute to weight gain). One critical ingredient unrelated to fat burning but deserving mention is BioPerine. This formula packs 5mg of it per serving, making it more absorbable.

While the user reviews of this bestselling thermogenic fat burner are overwhelmingly positive, it has to be noted that it might take a while before you see actual results. Even the manufacturer mentions that you should use the supplement for at least one month before you can expect a significant change. However, since lasting and safe weight loss is not something that you can expect to achieve overnight, this is hardly a major issue.  

Ingredients: green tea extract, L-tyrosine, DMAE, green coffee, L-theanine, Rhodiola root extract, vitamin B complex, BioPerine, caffeine anhydrous, cayenne pepper, vegetable capsule.

  • Rapid fat burning
  • Contain B-complexes
  • High green tea content
  • Might take a while to see significant results

EHP Labs OxyShred Thermogenic Fat Burner

  • Editor’s pick: Top-selling thermogenic fat burner powder
  • Servings per container: 60
  • Shipping: Free US shipping
  • Returns: A 30-day money-back guarantee
  • Discount: N/A
  • Price: $50.95

If you are looking for safe thermogenic fat burners that get the job done with little side effects, this supplement might be just what you need. Since it comes in nine flavors, there’s a high chance that even the pickiest consumers will find something to their taste in OxyShred’s catalog.

Below are the benefits you stand to enjoy by using this supplement:

  • increased metabolism
  • enhanced body energy
  • depleted fat stores
  • prevention of fat accumulation
  • memory and cognitive improvement
  • greater appetite control
  • increased bone and muscle mass
  • improved mood

The breakdown of fat stores is mainly caused by the acetyl L-carnitine. This ingredient latches onto fatty acids and shuttles them into the mitochondria, where they’ll be used up, and it has also been linked to improvements in memory and cognition. The supplement also contains ingredients that block the actions of fat-storage enzymes, resulting in the reduction of fat accumulation. Additionally, it contains raspberry ketones, an ingredient known to increase the body’s use of fat for fuel.

Additionally, this supplement contains appetite suppressants like conjugated linoleic acid (CLA), which ramps up metabolic processes and increases bone and muscle mass, further increasing energy expenditure.

Finally, this product also boasts guggul extract powder, which reduces hunger hormones (ghrelin) and increases the satisfaction hormone (leptin). That’s to say that this topselling thermogenic is capable of increasing serotonin and neurotransmitters that improve mood while suppressing appetite.

That’s not to say that there are no potential issues with this product. Namely, some of the people who gave this supplement a try claim that the powder was completely solidified upon delivery. While grinding it down might be a bit of a hassle, the powder is still perfectly usable, and fortunately, this doesn’t seem to happen too often.

Ingredients: acetyl L-carnitine, conjugated linoleic acid (CLA), Garcinia cambogia, guggul, grapefruit, raspberry, mango, green coffee, bitter orange, olive, L-glutamine, chromium picolinate, inulin fiber, L-tyrosine, vitamin C, taurine, huperzine A, caffeine anhydrous, niacin, pyridoxine HCl (B6), riboflavin (B2), cyanocobalamin (B12), thiamine mononitrate (B1)

  • Nine different flavors
  • Effective weight loss
  • Contains seven vitamins
  • Powder sometimes solidifies

Burn-XT Thermogenic Fat Burner

  • Editor’s pick: Most popular thermogenic fat burner on Amazon
  • Servings per container: 60
  • Shipping: Free US delivery
  • Returns: N/A
  • Discount: Save up to 15% on Amazon subscription orders
  • Price: $44.99

This supplement contains a relatively modest variety of ingredients, which is by no means a downside if fat burning is your goal. Like the other top supplements, it achieves weight loss by combining several ingredients that promote fat reduction without exposing you to unnecessary substances.

First, this thermogenic and appetite suppressant formula makes your body release fat stores for use by body cells. Secondly, it eases the movement of fats into the mitochondria for use as fuel to power your daily activities.

This supplement relies on acetyl L-carnitine HCl for breaking up fat stores and shuttling fats into the mitochondria. Aiding this process are two other ingredients – Capsimax cayenne pepper extract and BioPerine. The former mobilizes fats for use by the body, while the latter facilitates absorption.

These thermogenic fat burner pills are highly potent, partially thanks to 270mg of caffeine anhydrous per two-capsule serving. It’s also vegetarian-friendly and manufactured in a cGMP-certified facility. While there were some complaints about these pills having a slight acidic smell, according to the manufacturer, this is perfectly normal, and since the pills are not chewable, it shouldn’t be too much of an issue.

Ingredients: acetyl L-carnitine HCl, green tea extract, caffeine anhydrous, Capsimax cayenne pepper extract, BioPerine, hypromellose capsule, L-leucine.

  • Boosts metabolism
  • Suppresses appetite
  • No unnecessary ingredients
  • Slight acidic scent

BPI Sports B4 Thermogenic

  • Editor’s pick: Excellent thermogenic for belly fat
  • Servings per container: 30
  • Shipping: Free shipping on orders over $79.00
  • Returns: A 60-day money-back guarantee
  • Discount: Pay in four interest-free installments with Sezzle
  • Price: From $23.99

Most thermogenic fat burners have some side effects, but what differentiates the safe from the unsafe ones is the severity of these effects. This weight loss thermogenic supplement minimizes side effects by using as few ingredients as possible.

An important detail about this supplement is that it regulates the tissue in ways that target stubborn fats. Namely, it’s a keto-friendly supplement that increases energy by tapping into the body’s fat reserves. Containing a central nervous system stimulator, it enhances motor control, improves mood, and enables you to exercise longer.

If you want a stimulant-free product, this isn’t for you; one serving of B4 Thermogenic contains a similar amount of caffeine as three cups of coffee. Finally, this top thermogenic fat burner uses clear or white capsules with no artificial colors. Some of the people who have been using this supplement for a while claim that they developed some tolerance and had to take a break, but this is not too uncommon when it comes to fat burners based on caffeine. 

Ingredients: niacin, red wine concentrate, caffeine anhydrous, Dendrobium extract, sword bean, Psoralea, Japanese sophora, yohimbe bark extract

  • One-pill doses
  • Enhances mental focus
  • Provides motivation
  • Some users develop tolerance

Hunter Evolve Burn

  • Editor’s pick: Top-rated thermogenic appetite suppressant with no caffeine
  • Servings per container: 30
  • Shipping: Free US and UK delivery for two-bottle orders
  • Returns: A 30-day return policy for the US and Canada, and a 14-day return policy for the UK and other countries
  • Discount: Get one free bottle when you order three bottles
  • Price: $80.00

This amazing supplement by Hunter Evolve combines six different ingredients in a bottle of 180 easy-to-swallow capsules. What’s more, it doesn’t contain any artificial flavors or colors, preservatives, GMO, gluten, or soy. The manufacturing also follows strict cGMP standards.

It’s not easy to find a thermogenic fat burner review that’s not full of praise for this product. You’ll enjoy the following benefits from using this supplement:

  • boosted metabolism
  • suppressed appetite
  • reduced blood sugar
  • minimized calorie absorption
  • positive mood
  • muscle building

This formula uses tried and tested ingredients to achieve this effect. For instance, matcha green tea extract helps boost metabolism by 35%. There’s also vitamin D3 and cayenne pepper; the latter is rich in capsaicin – an ingredient that heats up the body.

Hunter Evolve Burn suppresses appetite using konjac root extract – a water-soluble dietary fiber that expands in the stomach to make you feel full. Konjac root extract also reduces blood sugar as it moves through the intestine. Finally, the supplement’s white kidney beans content prevents the digestion of carbohydrates, while mood-boosting L-theanine also helps reduce fat buildup. Of course, even the strongest weight loss pills are only likely to be effective if you make sure to exercise and maintain a healthy diet.

The main point of contention when it comes to this product is that the daily serving consists of six pills. However, while some users dislike having to take this many pills, others actually consider this a benefit, since the supplement is quite potent, and this type of dosing allows them to only take as much as they need, reducing the possibility of side effects.

Ingredients: konjac root, white kidney bean, cayenne pepper, matcha green tea, L-theanine, vitamin D

  • Caffeine-free
  • No flavors or additives
  • Contains dietary fiber
  • Daily serving consists of six pills

How to Choose the Best Thermogenic Fat Burner

Having gone through our detailed reviews of the top thermogenic fat burners, it’s only fitting we discuss what to look out for before purchasing one. This buyer’s guide touches on the critical factors that will influence your supplement choice. Let’s have a look!

What’s a Thermogenic Fat Burner?

Thermogenic fat burners accelerate the body’s metabolic actions regardless of any changes in physical activity, health condition, or eating habits. They combine different substances that increase internal heat generation, which burns fat.

Ingredients Used in Thermogenic Fat Burners

Caffeine, synephrine HCL, and yohimbe are popular metabolic stimulants used in thermogenic fat burners. These substances are associated with increased body energy, quickening heartbeat, increased concentration, and alertness.

Some of the other ingredients commonly used in these products include:

  • acetyl L-carnitine HCl
  • green tea extract
  • L-theanine
  • Rhodiola rosea root
  • cayenne pepper
  • DMAE (dimethylethanolamine)
  • green coffee
  • vitamin B complex
  • BioPerine
  • capsaicin
  • Garcinia cambogia

However, it’s important to note that the prolonged use of effective thermogenic fat burners may exert excessive pressure on the central nervous system, which is just one of the reasons you should always consult a doctor before you start supplementing.

Characteristics of a Good Thermogenic Fat Burner

There are three essential qualities that every good thermogenic fat burner must have, i.e., it should accelerate your metabolism, cause minimal side effects, and it needs to be affordable. Aside from this, you should also keep an eye out for products that contain additional beneficial ingredients, that are 100% organic, and that have all the necessary certifications. Finally, while most of them are universal, some of the top-quality fat burners for men aren’t suitable for women, and vice versa.

Recommended Shopping Procedure

The safest shopping procedure for any thermogenic fat burner is to consult your healthcare provider. However, before you do that, you need a way to decide which product might be right for you. Here are some considerations you have to make.

Health and Physical Status

Certain ingredients can be dangerous for people with particular medical conditions or pregnant/breastfeeding women. Taking your medical condition into account simplifies finding a suitable product. For example, even the most effective thermogenic fat burner can be dangerous for heart-disease patients.

Investigating the Ingredients

All thermogenic fat burners are likely to have side effects, especially with long-term use, even if they’re 100% organic. Calibrating your usage is the primary safety precaution, but the first important step is to check for any possible interactions of the ingredients with medications you might be taking and with any conditions you might be suffering from.

Here are the common thermogenic fat burner contraindications:

  • Increased heartbeat: This can be dangerous for people with a heart condition or high blood pressure. Since approximately 20% of adults in the US are unaware of having high blood pressure, we’d like to reiterate that you should consult a doctor before you start using a supplement of this kind. This contraindication may also cause discomfort by shortening your breath.
  • Hyper-alertness: The nervous system coordinates all body activities, physical and mental. Certain ingredients (like caffeine, for instance) directly impact the nervous system, so you should take them with caution.
  • Insomnia: Caffeine interferes with your ability to sleep by delaying the timing of your body clock, which reduces sleep time, or by heightening your mental alertness and body energy.
  • Headaches: Even toprated thermogenic fat burners can increase blood pressure. This can trigger a headache, especially when you haven’t eaten enough.
  • Diarrhea: Thermogenic fat burners may cause this side effect due to their action of accelerating fat-burning processes in the body.

Potency and Certifications

There are other ways to estimate the potency of a thermogenic fat burner aside from actually using it. Studying its constituents, examining certifications, reading expert reviews, and scanning user feedback are just some of the ways to do this.

Most of the effective thermogenic fat burners will have some of the following certifications:

  • non-GMO
  • vegan
  • USDA organic
  • kosher
  • halal
  • Origin Nutraceutical
  • NSF International


As a prospective buyer of thermogenic fat burners, you should be aware that these supplements often come with side effects, some of which can be especially dangerous to people with a heart condition, diabetes, or increased blood pressure. However, if your doctor gives you the green light and you carefully consider the ingredients in the product you have your eye on, these supplements can provide a range of benefits, resulting in significant weight loss.


Do thermogenic fat burners work?

Yes, thermogenic fat burners work. Their primary aim is to speed-up fat burning through metabolic processes, but they can also offer extra benefits depending on the type and quantities of ingredients used.

Are thermogenic fat burners safe?

Thermogenic fat burners are safe to use in the short term. However, prolonged usage presents certain challenges, including exacerbating some health conditions. There are also side effects like diarrhea and increased heartbeat, but these shouldn’t be serious if you purchase a good thermogenic fat burner.

What is the most effective thermogenic fat burner?

The most effective formula we tried is PrimeShred Hardcore Fat Burner. It’s highly potent and provides you with benefits beyond mere fat burning. What’s more, it combines many ingredients in adequate quantities and is designed to minimize side effects.

Do thermogenics make you sweat?

An effective thermogenic fat burner will likely cause some sweating. This is because it works on your metabolic system directly. Metabolism generates heat, and when the process is accelerated, this results in enough heat to make you sweat.

What’s the difference between a fat burner and a thermogenic?

There are at least six (up to eight) types of fat burners, and these are classified according to how they burn fat. Some suppress appetite, thus making you eat less; others block certain enzymes to minimize calorie absorption, and so on.

When it comes to thermogenics, they work by boosting the body’s heat-generating processes. Of course, even the best thermogenic fat burner won’t be able to provide impressive results if you don’t do your part, i.e., exercise and pay attention to your diet. In summary, all thermogenics are fat burners, but not all fat burners are thermogenics.
