    The 9 Best Non-Stim Fat Burners (2023 Update) – Fitnessnacks

    - Advertisement -


    When used judiciously — and we emphasize the word ‘judiciously,’ meaning used in conjunction with a well-planned diet and workout routine — the best non-stim fat burners can potentially help in a fat loss journey (though it’s worth noting diet and activity levels will still be the largest contributors in any weight loss plan). 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.

    Most fat burner products contain stimulants, like caffeine (although sometimes it’s yohimbine). Plenty of people are a little sensitive to these ingredients, or they want to take their pills at night time and don’t want to mess up their night of recovery and rest. We have compiled a list of the best non-stim fat burners on the market to help support all your fat-burning needs without any of the added stimulants.

    Best Non-Stim Fat Burner

    There can be a lot to think about when going into a fat-burning phase and picking the right supplement for your goals. This pick hits many of the essentials we like to see in a non-stim fat burner. It has a nice variety of ingredients, is third-party tested, and contains the amino acid carnitine, which may help you pack on muscle mass while also burning fat.

    Jacked Factory Lean-XT

    This non-stim fat burner earns the superlative thanks to the transparent and simple yet potentially highly effective ingredients list. Each two-capsule serving provides a solid dose of 750mg of acetyl-l-carnitine, which may help burn fat and boost your metabolism. (2)(3) You’ll also receive 500mg of green tea extract designed to provide clean energy and promote fat loss.


    Jacked Factory Lean XT

    Jacked Factory Lean XT

    This product contains 750mg of l-carnitine, 500mg of green tea extract, and 180mg of coleus forskohlii and forskolin. Plus, it has Bioperine to potentially help with absorption. 


    A moderate dose of 150mg of forskolin may boost metabolism, too, while also working to potentially suppress appetite and regulate blood sugar. Some people have trouble making the most of the ingredients in their fat burners. The five-milligram dose of black pepper extract in Lean-XT may help you absorb the other components more efficiently. Each 30-serving bottle costs around $34.99 or about $1.17 per serving, which is pretty cost-effective for a non-stim fat burner.

    Who Should Buy Jacked Factory Lean-XT

    • People looking for a fat burner that may help naturally increase energy, suppress appetite, and utilize fat stores will like this small but mighty formula.
    • Anybody on a budget will appreciate this rather affordable price point. 
    • Athletes may like the addition of the amino acid carnitine, which can potentially help improve muscle mass as well as fat loss. 

    Who Shouldn’t Buy Jacked Factory Lean-XT

    • People who are pill-averse may want to look for a once-daily fat burner. 
    • Folks who want a light jolt of caffeine will want to find a different fat burner since this one doesn’t have any. 
    • Those who aren’t interested in taking their fat burner as pills might want to look for a powdered option on this list. 

    Jacked Factory takes a multi-pronged approach to burning fat with Lean-XT. This has ingredients that work together to potentially boost metabolism, suppress appetite, burn fat stores, and even absorb ingredients better.

    Transparent Labs Stim-Free Fat Burner

    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. The first ingredient on the list for this supplement is acetyl l-carnitine, which one study found to have been significant in increasing muscle mass.

    Best Non-Stim Thermogenic Fat Burner

    Editor’s Note: This product contains Hordenine HCl, which is a known banned substance for athletes in the NCAA, Service Members, and possibly others as well. As with any supplement, be sure to read the ingredient label thoroughly before making it part of your supplement regimen.

    When it comes to burning fat, a thermogenic supplement can help to increase your body temperature in order to potentially create an environment in your body where more fat burning can take place.

    Huge Supplements Exterminate

    Thermogenic fat burners can help increase your body temperature to potentially help you burn more fat. One of the main ingredients in this formula that may help with this is stearoyl vanillylamide — this fat burner contains 20mg of this ingredient, which can have a similar metabolism-boosting effect to capsicum and other hot peppers. 


    Huge Supplements Exterminate

    Huge Supplements Exterminate

    Huge Supplements Exterminate green tea extract, which can potentially increase your metabolism. It also includes naringin and white willow extract, both of which can help with fat loss and weight management. 


    You’ll also find 600mg of green tea extract, 200mg of l-tyrosine, and black pepper extract, which can help your body absorb the other ingredients at a more efficient rate. This fat burner is a little pricier than some others on this list at three capsules per serving, with each serving costing $1.66.

    Who Should Buy Huge Supplements Exterminate

    • Folks who are specifically looking for thermogenic ingredients will like the stearoyl vanillylamide in this product. 
    • Anybody who wants a robust list of ingredients will appreciate the stacked list in this supplement.
    • People who want to make sure they’re getting the best absorption in their product will be happy to see black pepper extract making an appearance. 

    Who Shouldn’t Buy Huge Supplements Exterminate

    • Anyone who competes in NCAA sports, who serve our country, or who gets drug-tested for sport or for any other reason may want to thoroughly check ingredients and your banned substance list before consuming this supplement.
    • People who are looking for a budget-friendly buy — this is not the least expensive option on our list. 
    • Folks who don’t want to have to take three pills per day will want to look elsewhere.

    Best Research-Backed Non-Stim Fat Burner

    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.

    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. The combination of ingredients is supported by 26 peer-reviewed studies and features seven ingredients with clinically effective doses.

    Legion Phoenix Fat Burner

    Legion Phoenix Fat Burner

    Legion’s Phoenix comes with an extra absorbable form of synephrine and a high dosage of EGCG to promote its fat-burning properties. Each five-capsule serving provides 834 milligrams of Citrus Aurantium.


    You’ll also find ingredients to potentially aid in calorie burning — 50mg of forskolin, 100mg of black ginger, and 153mg of manuca pruriens. Phoenix is free of caffeine, so you don’t have to worry about becoming jittery or disturbing your sleep. It’s also priced well at about $29.99 (around $1.00 per serving). If you want to read the research, Legion has it readily available on their website. One thing to note is that each serving is three capsules — though they’re vegetable capsules, so they’re acceptable for vegetarians.

    • Buyers on a budget who are looking for a great combination of fat-burning ingredients at a lower price point will like the cost and label of this product. 
    • Anyone who values having the ingredients in their fat burner based soundly on the literature. Legion puts research at the front and center of this product.

    Best Non-Stim Fat Burner Pre-Workout

    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.

    Transparent Labs Stim-Free Pre-Workout

    For those looking for a non-stim fat burner combined with their pre-workout, this product is your answer. Choline can help play a role in the metabolism of fat, and this pre-workout contains 500mg of choline bitartrate. In addition, you’ll find traditional pre-workout ingredients, like 6,000mg of citrulline malate, 4,000mg of BCAAs, 4,000mg of beta-alanine, and 1,300mg of taurine. 


    Transparent Labs Stim Free Pre-Workout

    Transparent Labs Stim Free Pre-Workout

    An unusually powerful pre-workout that’s packed with clinically effective doses of ingredients linked to everything from power to endurance. All of this without the use of caffeine or other stimulants.


    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. For a pre-workout $1.60 per serving is a pretty reasonable price, especially considering how extensive the ingredient list and the potential benefits are. 

    Who Should Buy Transparent Labs Stim-Free Pre-Workout

    • Those who like to take powder supplements. This pre-workout comes in six different flavors.

    Best Non-Stim Fat Burner for Women

    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.

    Hourglass Fit 

    Research suggests that around 50 percent of women crave chocolate during the onset of their menstrual cycle, and Hourglass Fit includes ingredients that may aid in appetite suppression, like 3,000mg of glucomannan. (7) In order to potentially aid in burning more calories, each serving contains 100mg of cayenne pepper extract, which may have thermogenic properties. You won’t find any stimulants in here, so if you’re sensitive to caffeine, you’re in luck.


    Hourglass Fit Fat Burner

    Hourglass Fit Fat Burner

    This product contains 3,000mg of glucomannan, which can help you feel fuller to potentially reduce your appetite. It also contains cayenne pepper extract, 5-HTP, and black pepper extract (which can help you absorb all these ingredients). 


    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. The other downside here is that this fat burner, though high-quality, is on the expensive side at around $60.00 (about $2.00 per serving).

    Who Should Buy Hourglass Fit

    • Women who have problems with cravings might find some relief here thanks to the glucomannan. 
    • Anybody who wants a stim-free fat burner will like that this doesn’t have any caffeine.
    • Those who have trouble finding energy during calorie restriction. This has a dose of vitamin B12, which may help increase energy. 

    Who Shouldn’t Buy Hourglass Fit

    • People who are averse to taking pills may not like that you have to take four capsules with each serving of Hourglass Fit. 
    • Folks who want a fat burner that may include ingredients to spare or maintain hard-earned muscle mass might want to check out other options.
    • Women who want a powder or flavored fat-burning supplement.

    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

    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 Fat Burner

    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

    Leanbean

    This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you’ll find 50mg of caffeine for a subtle boost in energy. 


    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.

    Who Should Buy Leanbean

    • People who have trouble with their appetite during weight loss, LeanBean has a strong emphasis on appetite suppression.
    • Anybody who likes cayenne, garcinia Cambogia, turmeric, or green tea extract — these popular fat burner ingredients are well dosed in LeanBean.
    • Those looking to suppress appetite as their main way of losing weight and burning fat.

    Who Shouldn’t Buy Leanbean

    • People with a sensitivity to caffeine. The amount found in LeanBean is less than 10 percent of a small cup of coffee, but it’s worth mentioning.
    • Folks who like green coffee and raspberry ketones, it’s a little low on these ingredients.
    • Those who don’t want to take six pills each day.

    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 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

    Legion Phoenix Stimulant-Free Fat Burner has a stacked list of ingredients that may 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) 


    Legion Phoenix

    Legion Phoenix

    Legion’s Phoenix comes with an extra absorbable form of synephrine and a high dosage of EGCG to promote its fat-burning properties. Each five-capsule serving provides 834 milligrams of Citrus Aurantium.


    CFE comes in at 1,000 mg per serving in the Phoenix blend, making it a helpful ingredient in this toolbox to potentially lower stress and cortisol levels, and lead to better sleep and, in turn, better fat-loss capabilities. This ingredient list also contains 5-HTP, a natural serotonin booster, which can potentially improve mood, lessen anxiety, and give you a better night’s sleep, especially if you suffer from insomnia. (12) You’ll have to take three vegetarian capsules for a single serving of this fat burner, and it will cost you $1.66 per serving.

    Who Should Buy Legion Phoenix Stimulant-Free Fat Burner

    • Those who are looking to possibly lower their stress and cortisol levels, and in turn, may end up with a better night’s sleep, will appreciate the addition of CFE and 5-HTP in this formula. 
    • Athletes who want a fat burner with the addition of ingredients such as l-dopa to potentially curb cravings and appetite.
    • Anyone who wants ingredients that may help resolve insomnia and boost your mood will like the ingredients list on this product — especially 5-HTP. 

    Who Shouldn’t Buy Legion Phoenix Stimulant-Free Fat Burner

    • Folks who are looking for a basic formula may want to look elsewhere for a smaller ingredient list. 
    • Someone looking for a supplement fully geared towards sleep may want to look for a fat burner or another supplement that has sleep at the forefront— this supplement has the added benefit of ingredients that may lead to better sleep, but the focus is generally on fat burning.
    • Those who are on a budget can find a less expensive option on this list. 

    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

    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.

    Leanbean Fat Burner

    The best fat burners impact fat loss in multiple ways: boosting metabolism, appetite suppression, and increasing energy and focus. Leanbean came out on top because of its potent dosage and research-backed ingredients. This fat burner contains glucomannan, which can act as a natural appetite suppressant (thereby helping to reduce your cravings), and choline, which can help with fat metabolism. 


    Leanbean

    Leanbean

    This fat burner, geared towards women, promotes fullness with three grams of Glucomannan, and has B vitamins for more energy and focus. Plus, you’ll find 50mg of caffeine for a subtle boost in energy. 


    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. 

    Who Should Buy Leanbean

    • Anyone who wants a variety of ingredients working in concert to increase fat loss and energy expenditure.
    • People interested in energy boosters: Vitamins B6 and B12 are key for maintaining normal energy levels. 
    • Those who find a fat burner with appetite-suppressing ingredients to be appealing will enjoy this ingredient list. 

    Who Shouldn’t Buy Leanbean

    • People who don’t want to have to take a lot of pills. Leanbean requires six daily. 
    • Those with very sensitive stomachs, as glucomannan can cause digestive discomfort.
    • If you want a product free of caffeine entirely, you can find other options on this list that will work for you — this supp contains 50mg of caffeine. 

    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 Non-Stim 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. 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 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 Non-Stim 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.

    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.

    Best Non-Stim Fat Burner to Reduce Cravings Leanbean $59.99

    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.

    Lean Muscular WomanJacob Lund/Shutterstock

    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.

    FAQs

    Are non-stim fat burners still effective?

    Yes; although caffeine may be a helpful fat burning ingredient, there are many non-stimulant fat burning ingredients available that also have the potential to help you reduce body fat. Some of the ingredients you’ll find in these non-stim fat burners are chromium, cayenne pepper which is also called capsicum, carnitine, and choline. 

    Why would I choose a non-stim fat burner over one with stimulants?

    There are several reasons someone may opt for a stim-free fat burner. Some people may be sensitive to stimulants and choose not to include them in their diet. Some may prefer to get their caffeine intake from coffee or a caffeinated tea. Others may not like how stimulants make them feel later in the day. There is no right or wrong answer; it just boils down to what makes the most sense for your lifestyle choices.

    What are the downsides of a stim-free fat burner?

    Although there are no technical “downsides” as non-stim fat burners can be just as effective as fat-burners with stimulants, the only thing you’d be missing out on is another potential avenue for fat burning, as well as the heightened sense of alertness or focus some people receive from caffeine. 

    How much do stim-free fat burners cost?

    Stim-free fat burners can range in price, and on this list alone, you’ll find a range between around $0.33 and $2.00 per serving. The average price we found was about $1.12 per serving.

    What is the best non-stim fat burner?

    With such a plethora of options to choose from, we’re big fans of the simple yet effective formula of Jacked Factory Lean-XT. This transparent product features ingredients intended to boost metabolism and burn fat stores like acetyl-l-carnitine and forskolin. You’ll also find a dose of green tea extract, which may provide clean energy and burn fat. All that plus a cost-effective price tag make this a solid pick for anyone interested in a stim-free fat burner.
