Whether you’re preparing for your first bodybuilding show or just focused on burning fat for your own benefit, it may be worth looking at these supplements.

Non-stimulant fat burners are out there, but they can be hard to find. Not to worry — we’ve put together a list of the best non-stimulant fat burners on the market to help support all of your fat-burning needs without any of the added stimulants.

Pros

• The ingredient list is small, but this fat burner can increase energy while possibly promoting good sleep.

• The green tea extract can help increase fat loss.

Finding an effective fat burner with zero stimulants can be tricky. But with its simple, yet effective ingredient list, Jacked Factory Lean PM gets the job done — that’s why we named it the best non-stim fat burner overall. 

This formula has a variety of ingredients with zero fillers or dyes, including 300mg of green tea extract, which can help promote weight loss, according to the Cleveland Clinic. Each two-capsule serving also provides a solid dose of 200mg of l-theanine, which can help reduce stress and improve sleep quality, per the Cleveland Clinic. Paired with five milligrams of melatonin and 150mg of magnesium — two ingredients that may help promote good sleep, according to the National Sleep Foundation — this non-stim fat burner is ideal before bed.

You also get 10mg of vitamin B6, which helps promote a healthy immune system and nervous system, according to the Mayo Clinic. Plus, the five milligrams of black pepper extract in Lean-PM may help you absorb the other components more efficiently, per the Cleveland Clinic.

Jacked Factory takes a multi-pronged approach to burning fat with Lean-PM. Together, these ingredients potentially promote weight loss while encouraging good rest.

Best Non-Stim Fat Burner for Muscle Growth: Transparent Labs Stim-Free Fat Burner

Specs

• Active Ingredients: Green tea leaf extract, forskolin, bioperine
• Price: $54.99
• Capsules: 120
• Serving Size: 2 capsules

Pros

• The l-carnitine can help maintain muscle during a cut, which is great for bodybuilders prepping for competition.
• Users may absorb more of the ingredients, thanks to the included bioperine. 
• At under a dollar a serving, this is one of the most affordable fat burners you’ll find.

Cons

• There’s no caffeine, so if you want a stimulant, you’ll need to go elsewhere. 
• Bioperine is made from black pepper, so if you’re allergic, steer clear of this product.

Losing muscle can be the scariest part of trying to get leaner. With Transparent Labs Fat Burner, your shreds don’t have to come at the expense of your muscle gains. 

Transparent Labs has two different fat burners, one of which has stimulants. This non-stim fat burner is high in ingredients that could help with retaining hard-earned muscle mass — especially the Capismax that can provide an energy boost in the gym, which is useful for bodybuilders on a cut. Capsimax may also help increase thermogenesis, as can the green tea leaf extract, in this formula. 

The forskolin included here can help free the fatty cells from tissues, making them more available to be used as energy sources, which can also help bodybuilders push out more reps in the gym (or burn off more calories on the stair stepper). Plus, the bioperine here can help your body absorb more of these ingredients, leaving less to turn into waste material. 

Keeping your workouts going during a calorie deficit can be hard for bodybuilders. But you don’t need stimulants like caffeine, since this fat burner uses ingredients like green tea extract that can turn fat into energy for a boost during a bodybuilder’s cut.

If you’re putting something in your body and spending your hard-earned money on a supplement, you probably want to ensure that the ingredients are backed by research. That’s why we really like Legion Phoenix Stim Free.

This fat burner from Legion is about as good as it gets when looking for a product that is supported by the literature.

Phoenix is free of caffeine, so you don’t have to worry about becoming jittery or disturbing your sleep. If you want to read the research, Legion has it readily available on their website. And here’s good news for vegetarians — they’re vegetable capsules, so they’re acceptable for people avoiding animal products. 

If you won’t settle for just any fat burner and want only ingredients that are supported by the research then you will like Legion Phoenix Stim Free. Its seven clinically dosed ingredients are supported by 26 peer-reviewed studies and priced well to boot.

Best Non-Stim Thermogenic Fat Burner: Jacked Factory Lean-PM

Specs

• Active Ingredients: Green tea extract, 5-HTP, naringin, forskolin, white willow extract
• Price: $49.95
• Capsules: 90
• Serving Size: 3 capsules

Pros

• The stearoyl vanillylamide (a compound in capsaicin, an ingredient found in hot peppers) in this product can help ramp up the body’s thermogenic abilities. 
• This product has a longer list of potentially fat-burning ingredients than some of our other selections. 
• The included bioperine can help the body absorb this supplement’s ingredients, per the Cleveland Clinic. 

Cons

• This is not the least expensive option on our list. 
• The three pills per day dosing may not be ideal for people who don’t like taking pills. 

When burning calories is your priority, consider a thermogenic supplement. Thermogenic fat burners can help increase your body temperature to help you potentially burn more calories. In this formula, you get 300mg of green tea extract, an ingredient that may have thermogenic properties. (1)

You’ll also find 200mg of l-theanine, which can help promote good sleep, especially when paired with the five milligrams of melatonin and 150mg of magnesium. Jacked Factory offers a thermogenic fat-burning product that contains a stacked list of ingredients that may help you reach your goals by potentially promoting thermogenesis. The added black pepper extract can help this product absorb better, as well.

Best Non-Stim Fat Burner Pre-Workout: Transparent Labs Stim-Free Pre-Workout

Specs

• Active Ingredients: Green tea leaf extract, forskolin, bioperine
• Price: $54.99
• Capsules: 120
• Serving Size: 2 capsules

Pros

• This is a pre-workout that doubles as a fat burner, which is great for people who like to stack products.
• The powder format is ideal for people who don’t like taking pills.
• It comes in six fruit-based flavors. We recommend Sour Grape.

Cons

• This is pricier than many options on this list, so if you’re on a budget, you may want to look elsewhere. 
• If you don’t need a pre-workout, you should look at a different fat burner

For those who prefer to take their fat burner as a pre-workout in hopes of boosting your intra-workout fat burn, this may be the product for you.

For those looking for a non-stim fat burner combined with their pre-workout, this product is your answer. In addition to traditional pre-workout ingredients like 6,000mg of citrulline malate, 4,000mg of BCAAs, and 4,000mg of beta-alanine, this pre-workout contains 500mg of choline bitartrate, which can can help play a role in the metabolism of fat. 

You only need one scoop mixed with water for a full dose, but this product is a bit pricier due to the robust ingredients list. However, it does come in six delicious flavors — Strawberry Lemonade, Sour Grape, Blue Raspberry, Green Apple, Tropical Punch, and Orange. 

If you’re already keen on taking pre-workout, this product can allow you to combine your pre-workout and fat-burning supplement. While it may seem more expensive upfront, it can knock out two supplements in one go, which may actually end up costing you less in the long run.

Best Non-Stim Fat Burner for Women: Hourglass Fit

Specs

• Active Ingredients: Glucomannan, cayenne pepper extract, B12, chromium, vitamin B6
• Price: $60
• Capsules: 120
• Serving Size: 4 capsules

Pros

• Designed specifically for women, this fat burner is loaded with micronutrients like chromium and vitamin B6. 
• The glucomannan included may help suppress your appetite.
• There’s no caffeine here, making it ideal for people with caffeine sensitivities. 

Cons

• You have to take four capsules per day, which isn’t great for people who don’t like taking pills. 
• If you’re interested in keeping muscle while you burn fat, you may want to check out a fat burner with l-carnitine.

Hourglass Fit, although stim-free, contains an all natural formula, which may be helpful for women who want to burn fat. It also has a ton of glowing reviews and testimonials, which might boost your confidence in its efficacy.

Research suggests that around 50 percent of women crave chocolate during the onset of their menstrual cycle, and Hourglass Fit includes 3,000mg of glucomannan, which may help curb these cravings. (7) In order to potentially aid in burning more calories, each serving contains 100mg of cayenne pepper extract, which may have thermogenic properties. 

When you’re in a calorie deficit, you may find energy hard to come by, which is why this product contains 100 percent of your daily value of B12. You’ll also find 125mcg of chromium and 1,700mcg of vitamin B6 — which might help with regulating your blood sugar. We should note that each serving requires you to take four capsules, which some people may not like. If that isn’t a big deal for you, then this is a solid fat burner option — especially for women, thanks to the appetite suppressant ingredients.

For women trying to lose a significant amount of weight, chromium and vitamin B6 may be beneficial ingredients to help you shed extra body weight. If you’re a woman who struggles with cravings, then you may also find the dose of glucomannan helpful to potentially take the edge off.

Best Non-Stim Fat Burner for Appetite Suppression: Leanbean Fat Burner

Specs

• Active Ingredients: Glucomannan, cayenne pepper extract, green tea extract, black pepper extract
• Price: $60
• Capsules: 180
• Serving Size: 6 capsules

Pros

• The glucomannan fiber in this can increase satiety, lowering your urge to eat.
• Leanbean includes cayenne, garcinia Cambogia, turmeric, and green tea extract — all ingredients that may help the body burn fat.
• The low 50mg of caffeine gives a mild energy boost. 

Cons

• If you are sensitive to caffeine, you should know that there is a mild dose here. 
• At $2 a serving, this is a pricier fat burner. 
• Six pills a day is a lot to swallow.

Appetite can be a huge barricade when it comes to hitting your fat loss goals. With movement and calories burned correlating to how hungry you become, it can be a difficult balance to be burning the right amount of calories for fat loss while also making sure you are satiated. Leanbean’s potential appetite suppression may be the ticket to finding the balance.

Leanbean has a dozen ingredients, but it has a strong focus on what might be the most important aspect of weight loss: your appetite. A big part of the appeal is glucomannan, a thickener made from the root of the konjac plant that research suggests can suppress appetite. (8) The ingredients list also has other fat burner stalwarts like cayenne pepper, green tea extract, and black pepper extract, which a 2016 paper found may increase metabolism. (9) It’ll require you to take six pills daily, so if that sounds daunting, you may want to opt for a fat burner with fewer pills per serving.

Leanbean fat burner seems a little low in green coffee extract and raspberry ketones, but we were pretty impressed. It contains a small amount of natural caffeine — 50 milligrams — which is less than a cup of coffee.

LeanBean’s tiny amount of caffeine may disqualify it for some consumers, but for the average person, it’ll be barely noticeable, and it’s otherwise a terrific product.

Best Non-Stim Fat Burner for Sleep: Legion Phoenix Stimulant-Free Fat Burner

Specs

• Active Ingredients: 5-HTP, caralluma fimbriata, Thai ginseng, forskolin
• Price: $49.97
• Capsules: 90
• Serving Size: 3 capsules

Pros

• The CFE and 5-HTP in this formula may help decrease anxiety, making it potentially easier to fall asleep. 
• Ingredients like l-dopa can potentially curb cravings and appetite.
• The capsules are vegetarian, which works for people who want to avoid animal products.

Cons

• Folks who are looking for a basic formula may want to look elsewhere for a smaller ingredient list. 
• Three capsules a day is a lot for people who hate swallowing pills.
• There are cheaper options on this list.

Legion Phoenix Stimulant-Free Fat Burner has a strong ingredient list to potentially help you burn fat while curbing your appetite and cravings — but it also includes ingredients that may aid in your sleep and impact your memory of your dreams.

Legion Phoenix Stimulant-Free Fat Burner has a stacked list of ingredients that may help you sleep, as well as aid you in your weight-loss journey. Among the list of ingredients is Caralluma Fimbriata extract (CFE), which has been shown to reduce stress and anxiety in adults. (10) When our stress and anxiety are lowered, the outcome may lead to better sleep. Another study found that there is a statistically significant relationship between high stress and poor sleep, meaning it can be extremely helpful to lower stress levels to improve sleep quality. (11)

On the fat-burning side, the 100mg of Thai ginseng, 50mg of forskolin, and 30mg of grains of paradise can help ramp up your metabolism. There’s also 150mg of 5-HTP, a natural serotonin booster, which can potentially lower your food cravings.

Legion’s Phoenix Stimulant-Free Fat Burner is ideal for those who want their fat burner to possibly aid as a sleeping agent, as well. This formula contains 5-HTP, as well as CFE, which may lead to lowered stress levels and potentially improved sleep.

Best Non-Stim Fat Burner To Reduce Cravings: Leanbean Fat Burner

Specs

• Active Ingredients: Glucomannan, cayenne pepper extract, green tea extract, black pepper extract
• Price: $60
• Capsules: 180
• Serving Size: 6 capsules

Pros

• This supplement focuses on appetite suppression with its 3,000mg dose of glucomannan.
• The Vitamins B6 and B12 can help maintain energy levels during a calorie deficit. 
• There’s a small 50mg dose of caffeine for those who want an energy boost.

Cons

• You have to take six pills a day, which is a lot, especially if you don’t like taking pills.
• This supp contains 50mg of caffeine, so if you’re looking to avoid it entirely, this isn’t the supplement for you. 

Cravings are one of the forefront issues when it comes to fat loss. This formula contains natural appetite suppressants, which can lead to a decrease in cravings, as well.

Most fat burners include ingredients that boost metabolism, but the best ones can also help keep you from overeating in the first place. Leanbean nails both with its 3,000mg dose of glucomannan, which can act as a natural appetite suppressant (thereby helping to reduce your cravings), and choline, which can help with fat metabolism. 

Plus, you’ll find vitamins B6 and B12, which can help with your energy throughout the day. This product is marketed to women, but it’s a solid non-stim fat burner across the board — one of the only downsides is that you do have to take six capsules a day for a full dose. It’s also worth noting that this product does contain 50mg of caffeine, which is much less than a single cup of coffee, but not inconsequential. 

We like Leanbean for its wide variety of fat-burning and appetite-suppressing ingredients. If you’re okay with taking a decent number of pills, this supplement is the way to go to potentially help suppress your appetite or reduce cravings overall.

The Benefits of Stimulant-Free Fat Burners

While there are many potential benefits to supplementing with a fat burner, non-stim fat burners offer their own unique benefits. Whether you’re looking to increase thermogenesis, boost fat oxidation, achieve a higher metabolic rate, decrease appetite, or just avoid the poor sleep that may occur when you take stimulants, we detail each potential benefit below.

Non-Stim Benefits

When you opt for a stim-free fat burner, you choose to forego the caffeine or stimulants that are often utilized as fat-burning ingredients. There are many potential benefits to choosing the non-stim route, and it may be the best choice for you if you enjoy getting your stimulants from a caffeine source like coffee, or if you’re on medications that are already loaded with stimulants. It’s also a great choice for those who are easily affected by stimulants but still want a fat-burning supplement to assist them in their fat-burning quest. 

Increased Thermogenesis

Thermogenesis is the process of heat generation in the body, which may help burn more calories through increased heat. A thermogenic aid may increase thermogenesis, and therefore, potentially increase calories burned. This includes energy expenditure from ingesting, digesting, and processing the food we eat. (13) 

Not all fat burners are created with thermogenesis in mind, but if you’re interested in the potential benefits of thermogenesis, make sure you pick a supplement that states it is a thermogenic aid. It is worth noting you probably won’t burn a ton of extra calories, but if your end goal is fat loss and your diet, cardio, and resistance training set you up for success, this can be a potentially helpful tool for that extra push. 

Increased Fat Oxidation

Fat oxidation is the process that breaks down fat stores in the body (triglycerides) that we accumulate from taking in excess fat that we do not burn throughout the day in our daily activities. In order for the body to target fat oxidation over other types of energy releases, you may have to work out at higher intensities — specifically, endurance training that lasts less than two hours can help facilitate fat oxidation. (14) Fat oxidation may also be a byproduct of some fat-burning supplements. 

Increased Metabolic Rate

The metabolic rate — also known as the basal metabolic rate — is the number of calories that are necessary for the body to perform its various functions while it’s at rest. Some fat burners have the potential to increase metabolic processes and in their wake, help you burn more calories. 

Decreased Appetite

The science-backed way to lose weight is by burning more calories than you are taking in. Many know this as CICO, or calories in versus calories out. By supplementing with a fat burner that aims to decrease your appetite, you may have fewer cravings, food binges, or desires to consume an excessive number of calories.

Although sticking to a diet plan, macro breakdown, or good program will be your best friend here, a supplement that may help decrease your appetite can be a helpful tool, as well.

How We Chose the Best Stimulant-Free Fat Burners

When assessing the usefulness of a fat burner supplement, we looked at several factors. Sure, it has green tea extract, but is that enough? Here’s what you should think about.

Fat Oxidation

Perhaps the most popular ingredient in “fat burners” means it helps to burn fat, or more specifically, it helps to increase the amount of energy you burn from stored fat compared to stored carbs. Popular examples include green tea extract and l-carnitine.

Increasing Metabolic Rate

Increasing metabolic rate can be described as whether or not a product burns more calories. A popular example is cayenne peppers, which some research has found to burn an extra 50 or so calories, depending on the dosage. Other examples include hordenine and synephrine.

Appetite Suppression

There are a few ways appetite suppression works. A popular one is with ingredients that expand in the stomach, like glucomannan (found in LeanBean) and psyllium husk. A more popular method is 5-HTP, which may help with serotonin production, which appears to help with satiety and cravings.

Transparency

Scores of fat burners hide their ingredients behind proprietary blends so that the customer doesn’t know the exact amount of each. It helps them to keep their formula from being stolen by competitors, sure, but it also means that you don’t know how effective the product is.

What to Avoid in Non-Stimulant Fat Burners

While many fat burners in this category claim to be stimulant-free, there are still ingredients that some may want to avoid. For example, some non-stimulant fat burners have mild doses of caffeine, which can have a negative effect on people who are very sensitive to it. Also, keep an eye out for substances you might be allergic to, since ingredient lists don’t always contain an ingredient’s common name. Finally, athletes should keep an eye out for banned substances.

Small Doses of Stimulants

Occasionally, you’ll find smaller amounts of caffeine even in non-stim fat burners. They’re included to help provide a boost of energy, however small, to the mix. While 50 to 80mg may not affect most people, those who are sensitive to caffeine should keep an eye out for it when shopping for a fat burner.

Allergens

Two common ingredients in fat burners are cayenne pepper and black pepper extracts. Both of these ingredients can help speed up metabolism; black pepper has the added benefit of potentially helping the body’s digestion and absorption. However, some people are allergic to one or both of these ingredients, and should look for fat burners that don’t contain them. Be careful when reading ingredient lists, because often, they’ll be listed as the ingredients’ brand names or active chemicals like bioperine or capsaicin.

Banned Substances

If you’re an athlete or anyone else who may be tested for banned substances, you should know that some fat burners contain substances that could get you popped. For instance, Hordenine HCl, a chemical naturally found in barley, is a common ingredient in fat-burners, but is banned in many competitions, as well as by the Department of Defense. 

Non-Stimulant Fat Burners Precautions

If you are thinking about taking a non-stimulant fat burner, there are a few precautions that you can take to maximize your safety and the effectiveness of whichever fat burner you go with. 

First, as with any supplement, you should check with your doctor to see if whatever you’re considering is safe for your current health status and if it will be safe to use with any medications you might be taking. 

Also, make sure you take the recommended daily dosage. It may be tempting to take more than instructed in an effort to speed up the process, but you likely won’t experience better results and it may put you at risk for adverse side effects. 

And if you have a history with eating disorders or disordered eating, do not use fat burners.

How Much Do Non-Stim Fat Burners Cost?

Non-stim fat burners vary in their design, purpose, and ingredient list, which will affect the price point of each product. This list ranges in price from around $0.33 to $2.00 per serving, with many of the higher-priced products offering a more robust ingredient list.

The average price of non-stim fat burners lies right around $1.12 per serving. If an ingredient list is extensive, high-quality, and third-party tested, the price tag will most likely be higher to match the perks of the supplement. You can assess your needs and desires in a non-stim fat burner, and it’s likely you’ll be able to find a non-stim fat burner that’s within your budget to match.

What To Consider Before Buying Non-Stim Fat Burners

These products are prone to exaggeration on the part of the manufacturers and wishful thinking by consumers. Make sure you’re mindful of these points.

Know Your Calories

Way too many people think adding a fat burner, with no other changes to their diet, will produce a six-pack. Fat burners might help burn some extra calories, but if you don’t know how many calories you’re burning, it’s a moot point.

Find out your ideal calories with a macro calculator — then adding a fat burner might give you some support.

Manage Your Expectations

It’s generally understood that a pound of fat loss per week is very fast, and you can maybe get to two pounds if you’re quite overweight or obese. Anyone who says they lost 20 pounds in a month is exaggerating — you need to be patient.

Exercise Regularly

Many of the ingredients linked to fat oxidation produce their best results with a solid exercise routine: They’re meant to increase the amount of fat burned during exercise.

In addition, exercise helps to burn more calories and improve body composition. Taking a fat burner without a workout routine may produce suboptimal results.

Speak to a Physician

This is absolutely key. It would be best if you never made any changes to your diet or exercise regimen without first speaking to a doctor. This is especially the case with easily misunderstood supplements like fat burners.

Final Word

Fat burners are meant to act as an aid for fat-burning goals in conjunction with a solid diet or meal plan, resistance training, and a cardio routine. Fat burners are not magic pills that will land you a top spot on the before and after picture list, but they can be a helpful tool to get you closer to your goals. If you’re sensitive to caffeine or just prefer to get your caffeine from a source outside of your fat burner, this list is chock full of excellent fat-burning supplements sans the stimulants. 

As you can see, there are many things to keep in mind when choosing the best non-stim fat burner, even when you’re trying to uncomplicate the ingredients list by removing caffeine. The right product totally depends on your own preferences, but we’ve found many non-stim products that operate on multiple fronts: potential appetite suppression, fat oxidation, and increased thermogenesis. Whatever your preference, there’s likely an option for you on this list.
