Best Stimulant-Free Fat Burner Reviews
What did you think of our Top 10 Stimulant Free Fat Burners? You may still be on the fence about which burner is best for your weight loss journey or which type of supplement will help you achieve your goal the fastest. Allow our individual reviews below to help guide you and be sure to continue on after the reviews for additional tips on how to shred fat and melt body fat.
QuadraLean Stimulant Free
The RSP QuadraLean weight-loss system is one of the most effective currently on the market. RSP specially formulated both QuadraLean and QuadaraLean Stim-Free to attack fat from every angle. The non-stim version contains clinically-researched ingredients that act as appetite suppressants, metabolism boosters, and fat burners. This is the multi-faceted approach that’s the current gold standard.
Another reason we chose QuadraLean Non-Stim as our top stimulant-free fat burner is that it does not contain any proprietary blends, so you know exactly how much of each ingredient you’re getting per serving. The active ingredients in Quadralean Non-Stim are:
- ChromeMate® (as chromium polynicotinate)
- Green Tea Extract (50% EGCG)
- L-Carnitine
- Innobio® CLA 60%
- Paradoxine® Grains of Paradise Extract
A simple yet effective fat burner minus the harsh stimulants, what’s not to like?
- Awesome before & after photo results
- A marked drop in body fat %
- No jitters
- Okay to stack with caffeinated supplements or around your coffee
- Real weight loss reports
- Noticeable increase in muscle definition (thank the CLA and L-carnitine)
- Safe to use long-term unlike dangerous fat burners
- Maintain muscle mass while burning fat (this is very important to us)
- Cut sugar cravings out
- An effective supplement for all weight-loss and fitness journeys
- Complements a Ketogenic Diet quite well
- Recommended by PCOS sufferers
- More Energy
- You may not experience the positive results others are experiencing
- May cause stomach cramps
- Not the best appetite suppressant in our Top 10
- Several reports of increased food cravings
- The CLA dose may be too light for some people
LeanMode Stimulant Free Fat Burner
The makers of LeanMode, Evlution Nutrition, are one of the top-dog supplement companies in the bodybuilding realm. Evlution Nutrition’s line of fat burners and BCAA supplements is nothing short of impressive. When you invest in an Evlution Nutrition supplement, you invest in a supplement that’s trusted by professional trainers and bodybuilders alike.
What makes LeanMode the best stimulant-free fat burner on the market? What we like the most about LeanMode is the decaffeinated Green Coffee Bean Extract. Green Coffee Bean Extract is one of the most common and effective ingredients you’ll find in nearly every top fat burner. Reaping the benefits of this ingredient minus the caffeine is one feature that sets LeanMode apart from its competitors.
The combination of CLA and Green Coffee Bean Extract supports glucose metabolism and encourages the body to enter a state of ketosis, aka burn fat as fuel instead of carbs & fats. Lastly, unlike QuadraLean, LeanMode contains 500mg of Garcinia Cambogia per serving with a 60% Hydroxycitric Acid (HCA) concentration level. Expect stim-free energy and effective fat-burning with this professional-grade supplement.
- Awesome ab-shredding action as portrayed in the before & after photos
- An overall reduction in body fat % and the appearance of cellulite
- One of the best quick weight loss supplements on the market
- Jitter-Free Energy Boost
- One of the top stop-food-cravings supplements
- Effectively stop sugar cravings
- Helps to break through tricky weight-loss plateaus
- May cause nausea when taken on an empty stomach
- The pills may feel large to you
- More than a handful of reports of the supplement not working
Hydroxycut Hardcore Next Gen Non-Stimulant
One of the most trusted players in the supplement industry is Muscletech, and they’ve been up there for quite some time. Why? The company consistently puts out superior products with scientifically-researched & proven ingredients. One feature you’ll notice on every Muscletech supplement is authentic cited studies related to one or more of the ingredients in the supplement.
If the stimulant version of Hydroxycut is too hardcore for you, then the Next Gen Non-Stimulant version could very well be your answer. The key ingredient in the non-stim version is a Robusta Coffee Blend containing C. canephora robusta standardized to 45% chlorogenic acids.
Participants in one 60-day study lost an average of 10.95 lbs by supplementing with C. canephora robusta standardized to 45% chlorogenic acids. The placebo group in the same study lost just 5.4 lbs. Both groups followed a low-calorie diet for the duration of the study.
The fact that the C. canephora robusta group lost double the weight shows how effective the key ingredient in Hydroxycut can be when combined with a low-calorie diet. We also want to point out that no stim-free fat burners work like magic, meaning a low-calorie diet is a near requirement to achieve real results.
- The strongest appetite suppressant
- Maintain energy while cutting carbs (a tricky feat)
- Lean out in one month with a proper diet
- An energy boost comparable to caffeine
- Harder workouts in the gym
- Enhanced focus
- Seriously impressive weight loss results
- A top Keto supplement
- May cause excessive sweating
- May interfere with sleep if taken too late in the day
- If you’re a fan of stimulant Hydroxycut, this version may feel too light to you
- May cause stomach upset
Cellucor CLK
Cellucor, most well-known for its C4 pre-workout supplement, also knows how to make a top stimulant-free fat burner. CLK contains two trademarked non-stim fat burners that you won’t find in the other supplements in our Top 10. The two ingredients are Razberi-K® Raspberry Ketones and Slimpro® Protein Hydrolysates of Blue Whiting (Micromesistius poutassou).
While the benefits of Raspberry Ketones are somewhat controversial, they are thought to assist weight loss through the breaking down of fat tissue. Slimpro® is a trademarked appetite suppressant.
What we like the most about this supplement is the combination of Raspberry Ketones, L-carnitine, and CLA to attack fat along with the addition of hunger control with Slimpro®. For most people, this is an effective one-two punch for weight loss, particularly to burn stubborn fat.
- Helps to burn stubborn belly fat
- Easy on the stomach (does not cause queasiness when taken on an empty stomach)
- A top fat burner supplement for breaking through weight-loss plateaus
- Fast weight loss results
- Reliable appetite suppression and hunger control that kicks in quickly
- A fat burner approved by bodybuilders
- May cause trouble sleeping if taken later in the day
- There are better fat burners for energy in our Top 10
- Pills are large
Lipo 6 Black Ultra Concentrate
Nutrex Research Lipo 6 is our top caffeine-free fat burner for people who prefer the convenience of one pill per serving. One of the drawbacks to a lot of fat burners on the market is the need to take many pills at once or several doses throughout the day. With Lipo 6, you get a powerful 100% stim-free & caffeine-free fat burner with just four ingredients in effective doses.
The key ingredient in Lipo 6 is also one of the key ingredients in QuadraLean Non-Stim, Paradoxine® Grains of Paradise Extract. Both supplements supply 25mg of Paradoxine per serving.
Two additional ingredients we like in Lipo 6 are BioPerine® Black Pepper (fruit) Extract for enhanced absorption and L-tyrosine for positive mood and better stress response (keeps cortisol at bay).
The clear advantage of Quadralean is the addition of CLA to complement the L-carnitine. Lipo 6 contains L-carnitine without the addition of CLA.
- Clean, jitter-free energy boost
- Works well for consistent weight loss when taken long-term
- Reduction in waist size
- Easy on the stomach
- May feel weak if you’re accustomed to the stimulant Lipo 6 version
- Does not work for everyone
The Best Fat Burner Ever
One problem we have with a lot of fitness supplements is the addition of “other ingredients” such as dyes. This fat burner is vegan all the way down to the capsule. It also contains one of the best carb blockers, White Kidney Bean Extract. If you’re down with this carb blocker, The Best Fat Burner Ever is the only supplement in our Top 10 that contains it.
It also contains another top fat burner, Forskolin. Forskolin may not be the best diet pill for weight loss, but it has shown promise to improve body composition and prevent weight gain in women (*).
- No jitters
- Hunger control
- Won’t affect sleep when taken at night
- Weight loss reports
- No side effects
- Not as powerful as other caffeine-free fat burning supplements in our Top 10
100% HCA Garcinia Cambogia
MagixLabs Garcinia Cambogia Ultra Extreme is the most amplified Garcinia Cambogia supplement on the market. The active ingredient that’s responsible for weight loss in Garcinia Cambogia is Hydroxycitric Acid or HCA. The main benefits of Garcinia Cambogia are hunger control to fight food cravings and its capacity to interrupt the body’s ability to create & store fat.
MagixLabs Garcinia is made in the USA, 100% vegetarian down to the capsule, and GMP certified. The company also claims to manufacture the only Garcinia Cambogia supplement on the market with a proven HCA concentration of 98 – 100%.
- A top appetite suppessant on the market
- Authentic weight loss reviews
- An all-natural energy boost
- Weight loss without making drastic changes to diet and exercise regimen
- Curb sugar cravings
- May cause GI issues
- Does not suppress all users’ appetites
- The positive effects may taper off
T6 STAR6URN-PM
If you’re keen on losing weight while you sleep and getting a better night’s rest, STAR6URN-PM is worth a serious look. Team Six Supplements is a rather new supplement company taking the same approach to win consumers over as The Genius Brand. T6 supplements are packed with trademarked ingredients with sufficient dosages without any unnecessary fillers.
We previously included a T6 supplement in our list of the best ab supplements, and we felt that STAR6URN-PM deserved the #10 spot on our list here as the top stim-free nighttime weight management supplement. One of our favorite supplements is KSM-66® Ashwagandha Extract for myriad reasons.
KSM-66 provides stress response support, testosterone support, cortisol blocker, appetite suppression, adrenal fatigue support, and too many additional benefits to list. STAR6URN-PM is the only supplement in our Top 10 that includes KSM-66 in its formula.
The second trademarked ingredient we like is InnoSlim®, which helps to reduce glucose absorption and boost fat cell combustion. Lastly, STAR6URN-PM contains a more-than-sufficient 5 mg dosage of melatonin per serving to ensure you get a deep restful night’s sleep for optimum recovery.
- Sleep like a baby (may succeed where other melatonin supplements failed you in the past)
- The best nighttime fat burner on the market
- Burn love handles and belly fat to expose abs in hiding
- A top cortisol blocker
- Reduce bloating
- A top cutting supplement
- Potential melatonin side effects (some users find it more difficult to sleep)
- Not all users experience weight loss results
Top-Rated Non-Stimulant Fat Burners
Before we share tips on how to shred fat, let’s take a closer look at several of the common ingredients in our Top 10 Stimulant-Free Fat Burners to help you understand how they work.
Paradoxine Benefits
Paradoxine® Grains of Paradise Extract is one of the more intriguing fat burners on the market. This trademarked form of Grains of Paradise Extract has shown promising fat loss results in human trials. The two key human trials both found greater energy expenditure in subjects who supplemented with Paradoxine (*). Another promising result was a reduction in visceral fat in the lower abdomen in women who supplemented with Paradoxine. Visceral fat is the stubborn fat that hides deeper than subcutaneous fat in your abdomen around your organs.
Here’s what we think is really cool about Paradoxine. There are two types of fat tissue in the body: white fat and brown fat. White fat cells are larger than brown fat cells. Research suggests that Paradoxine’s potential ability to turn white fat into brown fat is the reason behind its energy expenditure and weight loss benefits.
Benefits of Garcinia Cambogia for Weight Loss
The jury is out on whether Garcinia Cambogia is a top weight loss supplement (*), but if one thing is for sure, there’s more than enough anecdotal evidence proving its effectiveness. The main benefit of Garcinia Cambogia is its ability to suppress appetite. If you burn more calories than you eat (enter a caloric deficit), you give yourself the best chance of burning fat and losing weight.
The most promising Garcinia Cambogia study found that it may help to reduce belly fat accumulation in obese individuals (*). For maximum effectiveness, it’s best to stick with Garcinia supplements with higher concentrations of the active ingredient, Hydroxycitric acid (HCA).
Acetyl L-Carnitine Health Benefits
Acetyl L-carnitine or ALCAR is a very popular supplement among bodybuilders who are shredding or cutting. Like Garcinia, scientific evidence is mixed for L-carnitine in terms of being a weight loss supplement. Most supplement companies claim that ALCAR provides mitochondrial support and acts as a sort of delivery system to encourage the body to burn fat as fuel.
Where most people go wrong with ALCAR is underdosing and not taking it with a high-glycemic carb. Subjects who took 2g of L-carnitine with 80 grams of a high-glycemic carb 2X daily during a 24-week study burned 55% less muscle glycogen and 55% more fat than the group who took carbs only. The researchers measured the results while the subjects engaged in low-intensity cycling (*).
The reason ALCAR is a popular supplement among bodybuilders and less popular among common folk is that experienced bodybuilders have a much greater understanding of bodily processes, and L-carnitine supplementation is somewhat complicated.
How to Shred Fat
We put together a list of tips on how to melt body fat below to help you get the most out of your non-stimulant fat burner(s).
Magic Weight Loss Pills Don’t Exist
Non-Stimulant Fat Burners are NOT magic weight loss pills! When we see reports written by users who claim a fat burner “didn’t work,” we often realize that these dissatisfied customers made zero dietary or fitness changes. No fat burner on the market will magically melt fat away on its own. If there is a magic pill that does this, it would certainly cost a lot more than any supplement under $50.
Caloric Deficit for Fat Loss
One thing we always preach here is to go into a caloric deficit to get the best weight loss results. This means you must burn more calories than you eat. Effective non-stim fat burners act as appetite suppressants without giving you the jitters that often accompany caffeinated fat burners. Plus, the additional benefits of fat burners beyond appetite suppression are amplified when you give them a chance to work. Piling up daily food calories muffles any chance a natural fat burner has of working.
To quickly learn how to calculate a caloric deficit, we recommend the Calorie Calculator at calculator.net. Click Here to try it.
Follow a Low Carb Diet Plan
Our six-pack diet plan is low-carb and high-protein. You may have noticed buzz around the “Keto Diet,” which is a low-carb, high-fat diet. The Keto Diet encourages ketosis, the state of burning fat for fuel. Sure enough, the Keto Diet is effective, however, we prefer common sense over flashy diet names. Limiting carbs is a great place to start when your goal is to burn fat.
Intermittent Fasting to Lose Fat
Our favorite practice for weight loss is intermittent fasting. It’s been more effective for us over the years than any other weight loss practice. Intermittent fasting is when you allow yourself to eat for a set number of hours each day and fast during the remaining hours.
For most people, the best hours for intermittent fasting are 16 on and 8 off. This means you don’t eat for 16 hours of the day and eat during the other 8 hours. It may sound mighty difficult, but when you factor in 7-9 hours of sleep as part of the fasting period, it becomes a lot less intimidating.
Fasting is a way to reach ketosis (*). This is one reason intermittent fasting is an excellent practice for burning fat. We also find it easier to keep track of our calories and ensure we’re in a caloric deficit while intermittent fasting. Combining a caloric deficit with intermittent fasting may sound torturous, but it’s been the most effective tool in our weight loss shed for years.
To eliminate the chance of torture, we drink green tea during the fasting period for hunger control. You may have already noticed that most fat burners on the market contain Green Tea Extract for this very reason.
Bottom Line
At this point, you’re a fat-burning guru. The stimulant-free fat burners in our Top 10 are there to accommodate everyone’s needs and to help you achieve your fat-burning goals. You now have all the tools and knowledge you need to burn fat at home like a boss. Are you ready to get started?
