Fat burning supplements are among the most popular and effective ways to help people lose weight. Whether they burn body fat directly, help you control your hunger, or boost your energy levels to make working out easier, they're all beneficial for people losing weight.
However, most fat burner products also contain stimulants like caffeine. This can be useful for most people, but it's also an issue for people who can't or don't want to take stimulants, as it makes the already difficult job of choosing a weight loss supplement even harder.
That's why we have created our list of the very best non stimulant fat burners currently on the market. This should ensure everyone can find the perfect fat burning supplement for them, to help them take their weight loss to another level.

Hunter Burn – The Best Stim Free Fat Burner Overall
Hourglass Fit – The Best For Women
EVLution Leanmode – The Best Stim Free Fat Burner On A Budget
JackedFactory Lean PM – The Best To Take Before Bed
Leanbean – The Best For Cravings
Hunter Burn - The Best Stimulant Free Fat Burner Overall
Hunter Burn is a stimulant free fat burner that works to promote weight loss in multiple ways, but which works best as an appetite suppressant.
The Hunter Burn formula centres around 3,000 mg of konjac root extract (glucomannan) and 500 mg of white kidney bean 20:1 extract. These are then supported by l-theanine, matcha green tea extract, cayenne pepper extract, and vitamin d3.
Konjac root extract and white kidney bean extract are both appetite suppressants, but they work in very different ways.
Konjac root extract is a natural dietary fiber with very few calories. It significantly swells in your gut when it comes in contact with water, taking up a huge amount of room to make you feel full, avoid hunger pains and food cravings, stick to a diet, and remain in a calorie deficit.
It also slows the speed that food is released from your gut. This ensures it's fully processed and all the nutrients are used and sent where they're needed, preventing new fat cells from being created and you from gaining weight (1).
White kidney bean extract alters how your body processes carbs. Also known as phase 2, it stops your body from absorbing as much of the carbohydrate content of the food in your diet by inhibiting the digestion of dietary starches, keeping your calorie intake down.
This leads to your body absorbing fewer calories from anything you eat that contains carbs and also gives you better blood sugar control, as simple carbs will remain in your gut until they are either excreted with your waste or fermented by the bacteria in your colon (2).
L-theanine is an amino acid that's also said to offer a small amount of appetite suppression. Its best function in weight loss supplements though, is that it can aid your workout performance by enhancing your sleep quality, energy levels, focus, and recovery time (3).
Matcha green tea extract is also able to boost your energy levels and workout performance, and it can promote direct fat burning through thermogenesis, a process that raises your internal body temperature to boost your metabolism and make you burn fat and calories faster.
Its greatest selling point for weight loss though, is that it contains the antioxidant catechin EGCG.
Not only will this reduce inflammation and keep you pain free, to ensure you can engage in regular exercise, but it also helps clear the digestive tract and prevent bloating, which is a common issue people face when taking appetite suppressants (4).
Cayenne pepper extract contains the chemical capsaicin, which stimulates thermogenesis and works as an appetite suppressant. It also reduces inflammation and pain, making it easier to stick to both a balanced diet and a challenging workout routine (5).
Finally, vitamin d prevents you from storing body fat and gaining weight, aids with protein synthesis, and keeps your energy levels up, while preventing you from developing low testosterone levels, which could itself lead to weight gain (6).
This combination of effects will not only directly boost fat burning but it also ensures that you never miss a workout, perform better in those you complete, and recover faster afterwards, both mentally and physically, leading to all round better weight management.
This makes Hunter Burn the best non stim fat burner for most people and an especially good choice for anyone who struggles to stick to a healthy diet or low calorie intake.
Its formula promotes powerful appetite suppression and helps you stick to a healthy diet
Will boost metabolism, rest, relaxation, and recovery
Enhances energy production and your rate of fat burning
Aids workout performance to accelerate weight loss

Hourglass Fit - The Best Stim Free Fat Burner For Women
Hourglass Fit is a non stimulant fat burner that's been especially designed to promote the fat burning process and body weight loss, while taking all the needs of the female body into account.
Its formula contains Capsimax cayenne pepper extract, Bioperine black pepper extract, glucomannan, 5-HTP, chromium, vitamin B2, vitamin B6, vitamin B12, and zinc.
Capsimax cayenne pepper extract and glucomannan provide the same benefits we saw in Hunter Burn, including providing appetite suppression, stimulating thermogenesis, reducing inflammation and pain, and boosting digestion and your metabolic rate.
Bioperine black pepper extract also stimulates thermogenesis, but it's primarily included in supplements as it's a bioavailability enhancer. This means it's able to boost the rate of absorption and level of efficacy of all the other ingredients in the formula (7).
5-htp and chromium are appetite suppressants that work in different ways.
5-htp (5-hydroxytryptophan) is an amino acid that's able to cross the blood brain barrier to aid serotonin production. With higher serotonin levels, you'll feel happier, more satiated and relaxed, and enjoy better sleep quality, while experiencing less anxiety or depression.
This makes it easier to control your calorie intake and focus on your training to support weight loss, while 5-htp also stimulates stored fat loss directly (8).
Chromium is another appetite suppressant that boosts serotonin production, but it also optimises your blood sugar levels and nutrient absorption, and enhances the effects of all the other ingredients in the formula, to promote weight loss from a variety of angles (9).
The b vitamins all help you lose weight faster as they boost both your metabolism and rate of nutrient absorption.
They can also improve your nervous and immune systems, antibody and red blood cell production, cell respiration, bone marrow, DNA, and nerve sheath maintenance, and the repair of bodily tissues, to boost your health and ensure you never miss a workout (10)(11)(12).
Lastly, the mineral zinc stimulates the pituitary gland and aids the production of luteinizing hormone and testosterone, boosting lean muscle mass growth and preventing fat storage.
It also improves your DNA synthesis, energy levels, eyesight, immune system, metabolic rate, and recovery time, while reducing inflammation and the signs of aging (13).
By combining the effects of an appetite suppressant, fat burner, and energy booster into one supplement, Hourglass Fit tackles weight loss from every angle.
This makes it the best non stimulant fat burner for women seeking female fat burners to help them lose weight while taking care of the more delicate needs of their body, as does the carefully chosen dosages.
Provides appetite suppression, burns fat, and boosts energy levels simultaneously
All the ingredients are proven to promote fat burning and weight loss
The dosages are carefully tailored to the needs of the female body
A little pricey

Evlution Nutrition Leanmode - The Best Non Stim Fat Burner For People On A Budget
Evlution Nutrition Lean Mode is a stimulant free fat burner that's created with a low price tag to help people on a budget lose weight. Its formula contains conjugated linoleic acid (CLA), green coffee bean extract, acetyl l-carnitine, l-carnitine l-tartrate, and chromium picolinate.
Conjugated linoleic acid are fatty acids that interact with hormone receptors called PPARs (peroxisome proliferator activated receptors).
Doing this not only enhances your fat burning capabilities, but it also regulates your hormones and blood sugar levels, prevents weight gain, and reduces inflammation, to help ensure you never miss a workout (14).
Green coffee bean extract is a natural source of caffeine and the antioxidant catechin chlorogenic acid. Although there is some caffeine in here, it’s relatively negligible as most of it comes from the roasting process, delivering about 8mg per 100mg, meaning there’s less than 2mg here (a cup of coffee contains
Chlorogenic acid optimises your blood glucose and blood pressure levels and boosts your metabolic rate, health, and recovery time, while the natural caffeine makes you more energetic and helps you train harder, without experiencing crashes.
This helps you burn fat and calories faster and prevents sickness, injuries, and blood glucose spikes that lead to weight gain or stop you from exercising (15).
Acetyl l carnitine is an amino acid derivative of l-carnitine that improves fat metabolism, converts fatty acids into energy, and reduces blood sugar levels, all of which is beneficial to people losing weight.
It can also cross the blood brain barrier and, with its antiseptic and antibacterial properties, can help prevent your cognitive functions from deteriorating (16).
L-carnitine l-tartrate is a compound made of l-carnitine and a tartaric acid salt.
It speeds up the rate you burn fat by prioritising its use and depleting your stored body fat faster, while boosting your energy levels, making it easier to train harder, build lean muscle mass, and burn fat and calories faster.
Its antioxidant properties then reduce fatigue, muscle soreness, and muscle weakness, to ensure you recover quicker (17).
Chromium picolinate then works the same way as the chromium we looked at in Hourglass Fit, which is to suppress your appetite and boost your serotonin production.
The other good thing with the EVLution products is that there’s quite an active community around them as they’re owned by famous forum bodybuilding.com, this sort of grouping has been shown to have a benefit for people trying to lose weight as regular contact with other people going through the same challenges increases results. (18)
There are, admittedly, a couple of issues with Evlution Nutrition Leanmode that need to be pointed out though.
Not only do some of its ingredients only have a mild effect on fat burning and weight loss, but every single ingredient in the formula is present in a dosage that's lower than required to produce optimal effects.
However, this shouldn't come as too much of a surprise, given the product's extremely low price tag. So, while it won't produce dramatic weight loss, it may be the best non stim fat burner for people seeking modest body weight loss who are shopping on a budget.
Very reasonably priced
All the ingredients are proven to help with weight management
The entire formula is vegan friendly and gluten free
Will not produce dramatic weight loss
All the ingredient dosages are lower than is required to produce optimal effects
Burn Lab Pro - The Best Non Stim Fat Burner For Thermogenesis
Burn Lab Pro is unique among thermogenic fat burners as it contains no caffeine or stimulants of any kind. Instead, its formula consists of Capsimax cayenne pepper, chromium picolinate, HMB, forskolin, and piperine.
Most of the thermogenic effects of Burn Lab Pro are produced by the piperine (black pepper extract) and Capsimax.
Beyond raising your internal body temperature to increase fat metabolism, they also boost the bioavailability of the other ingredients in the fat burner, making them more effective.
Chromium picolinate then supresses your appetite, regulates your blood sugar, and boosts your absorption of nutrients and mental focus. This stops you cheating on a diet or eating more calories than you need, to fuel your workouts and prevent you from gaining weight.
HMB (hydroxy beta-methylbutyrate) is a naturally occurring chemical compound made by our bodies. A derivative of the powerful bcaa leucine, it's one of the primary building blocks for muscle and protein in the human body.
It prevents muscle protein breakdown and wastage, improves muscle recovery, and promotes lean muscle mass growth and strength.
This enhances your body composition and metabolic rate and helps you train harder, leading to significantly enhanced fat burning and weight loss (19).
Forskolin is an extract from the roots of the Indian Coleus plant that both releases stored body fat from its cells and boosts testosterone production. This boosts fat oxidation directly by creating enzymes called lipase and adenylate cyclase, while increasing your muscle mass.
This will aid muscle growth, prevent muscle breakdown, encourage body recomposition, burn fat, boost your metabolism, and prevent the creation of new fat cells, and maximize fat loss, as it prevents you gaining fat as you burn the stored fat you already have (20).
The only real issue with Burn Lab Pro is, while thermogenic fat burners normally do most of the work themselves, it requires a lot of effort on your part too, which is not ideal with a fat loss supplement that doesn't provide notable appetite suppression or boost energy production.
That said, if you're specifically seeking a thermogenic fat burner that doesn't contain caffeine, Burn Lab Pro is one of the best non stim fat burners available.
Capable of burning fat directly while using only natural ingredients
Free from any animal products or allergens
All purchases come with a 30 day money back guarantee
Requires a lot of effort on your part, despite not affecting your appetite or energy levels too much
The serving size is very large
Jacked Factory Lean PM - The Best Non Stim Fat Burner To Take Before Bed
Jacked Factory Lean PM is unique even among stimulant free fat burners as it's a night time fat burner designed to help you lose weight by enhancing body fat metabolism and improving your quality of sleep.
The Jacked Factory Lean PM formula consists mostly of ingredients we've already looked at in l-theanine, green tea extract, Bioperine black pepper extract, and vitamin b6. However, it also contains two new ingredients in magnesium and melatonin.
All the ingredients are scientifically proven to help you fall asleep faster and get more rest once you have.
Green tea extract enhances fat oxidation, boosts energy levels, and reduces inflammation. BioPerine also elevates fat oxidation while improving the bioavailability of the formula's other ingredients.
L-theanine enhances your sleep quality, energy levels, focus, and recovery time, while vitamin b6 enhances serotonin and melatonin production, boosting your mood and recovery time. This all leads to more effective workouts and body recomposition.
Magnesium is a mineral that's vital for over 600 reactions in the human body. It promotes physical and mental relaxation and calmness, soothes the muscles, and prevents cramping and dehydration, creating ideal conditions for both sleeping and working out (21).
Melatonin is a hormone secreted by the pineal gland. It regulates REM sleep, helps maintain a healthy sleep wake cycle, and makes it easier to fall asleep quickly, achieve a deep sleep, and stay asleep for longer. This optimises your recovery time and helps you lose body fat (22).
Admittedly, Jacked Factory Lean PM is one of the milder fat burner products on the market and won't produce dramatic fat loss.
However, it may just be the best non stim fat burner for people who want to lose weight while they sleep and combine the effects of a fat burner and a sleep supplement in one product.
Keeps you healthy and optimises your sleep pattern
Improves fat oxidation while you sleep
Promotes less fat loss than most fat burners
More effective as a sleep supplement than as a fat burner
Leanbean - The Best Non Stim Fat Burner For Appetite Suppression
The Leanbean fat burner supplement is designed primarily for women but its gluten free, plant based fat burning formula can be used to supress the appetite and aid the goals of everyone. Its low price is also ideal for people on a budget.
It contains nothing but natural ingredients and consists of glucomannan, green coffee bean extract, choline, chromium picolinate, chloride, zinc, turmeric, piperine, garcinia cambogia, acai berry extract, and vitamins b6 and b12.
We've already looked at glucomannan, green coffee bean extract, piperine, zinc, chromium picolinate, and the b vitamins, and know they can prevent weight gain and fatigue, boost metabolism, energy levels, and thermogenesis, and burn body fat stores to aid weight loss.
However, choline, chloride, turmeric, garcinia cambogia, and acai berry extract are all unique to Leanbean.
Choline is a substance similar to amino acids that's said to boost muscular contractions and focus and reduce inflammation. This will aid your exercise performance and make burning stored fat and building muscle mass much easier (23).
Chloride is an electrolyte that improves your energy levels, gut health, mood, and blood pressure, and treats certain illnesses, making sticking to a training routine much easier (24).
Turmeric boosts fat burning and prevents fat storage, while reducing inflammation which may cause you to miss workouts (25). Acai berry extract then further prevents inflammation (26).
Finally, garcinia cambogia contains hydroxycitric acid that may boost serotonin production, digestion and exercise performance and prevent hunger cravings, blood sugar spikes, and fat storage (27).
There are a few issues with the Leanbean fat burner that must be mentioned though.
While some of its ingredients need more research to prove exactly how they work, others are present in doses far lower than ideal. Also, it relies almost exclusively on appetite suppression and has very limited fat burning properties of its own.
Even so, if you're shopping for an appetite suppressant on a budget, Leanbean may be one of the best non stimulant fat burner supplements for you.
A good appetite suppressant
Can slightly boost metabolism, fat loss, energy production, and recovery time
Gluten free, vegan friendly, and uses only natural ingredients
There's little proof some of the ingredients help you lose weight
Not ideal to burn stored fat directly
Some customers have complained about becoming bloated and unable to work out
