You may have read that fat burners are dangerous because of the insane amounts of stimulants they contain. Some people react negatively to stimulants, while some simply don't like them.
This is why I highly recommend taking stimulant-free fat burners. You get the same benefits without the jitters or caffeine crash.
There's an overwhelming amount of products out there, so our team and I took the time to research and recommend the best ones on the market today.
Our Top Stimulant Free Fat Burners (2021 Updated)
HIGHLIGHTS & BENEFITS
OUR #1 RATED
#1 Performance Lab Fat Burner
#2 Transparent Labs
#5 RSP NUTRITION
1. Performance Lab Fat Burner
Performance Lab Fat Burner has some of the best-advanced nutrients that you will find in a fat burner. The ingredients include Forslean, Capsimax, and BioPerine.
The fat burner maximizes weight loss by using specially-formulated ingredients that increase thermogenesis (body heat) and calorie burning.
This fat burner was designed for fasted training, that is, working out while on an empty stomach. In theory, this will help burn more fat during exercise.
However, some users report that they use this too even if they don't do fasted training. Whether taken with fasted training or not, they still report apparent weight loss when combined with exercise and a healthy diet.
In our opinion, this is the best fat burner on the market right now for preserving muscle mass while you train in a caloric deficit. There's no waste here, no dead weight or bogus ingredients. Side effects are not a major concern. On top of everything, the price of Performance Lab SPORT Fat Burner is very reasonable. All in all, we're looking at a truly great fat burner here! - Live Magazine
2. Transparent Labs PhysiqueSeries Fat Burner Stim-Free
Transparent Labs made this non-stimulant fat burner for those who are sensitive to stimulants. It suppresses your appetite, targets fat storage, and boosts your power and metabolism - all without giving you the jitters from stimulants.
What I really like about this product is that they are completely transparent about their ingredients. There are no proprietary blends hiding the amount of the ingredients in their product. It's all clearly listed on their label.
Transparent Labs has a great deal when you buy in bulk. The more you buy, the more you save. So if you decide this product is the best for you, then I would recommend buying it in bulk for cost-effectiveness.
You'll have to remember to take this in the morning and afternoon, as the optimum recommendation is twice a day. At that rate, a bottle with 120 capsules would last for 60 days if taken daily.
3. Lean-XT Non-Stim Fat Burner
I appreciate that Lean-XT is transparent with its labels. It shows precisely the ingredients in the products. Even though it's stimulant-free, it does contain green tea extract, which may have some naturally-occurring caffeine. It is an ingredient that is proven to help with weight loss though.
It doesn't seem to affect the overall quality, as my research shows that people like this product because it suppresses their appetite without giving them the jitters.
Other ingredients include acetyl l-carnitine HCL, Coleus Forskohlii + Forskolin, and BioPerine, which is a black pepper extract. All of these ingredients help support weight loss, which makes this an ideal fat burner.
It's an affordable product with one bottle lasting 1 or 2 months, depending on your dosage. It's at an affordable price either way. If you're on the fence, they have a 30-day money-back guarantee.
4. Hydroxycut Hardcore Next Gen Stim-Free
This is one of the more affordable products available. Hydroxycut recommends taking 2 capsules a day, but you can take up to 8 capsules in a 24 hour period if you need it.
Hydroxycut conducted a study and found that users lost an average of 3.7 pounds in 8 weeks with a calorie-reduced diet and moderate exercise.
This product contains C. canephora robusta, which is a coffee bean extract. A study showed that people who took 200mg of this extract lost an average of 10.95 pounds in 60 days with a low-calorie diet.
They have key weight loss ingredients that are scientifically tested. They do all this without using stimulants.
It took some digging around the Internet to find their nutritional label. I wasn't too impressed with it. Their "Other Ingredients" is pretty long and contains things like food coloring and artificial flavor. I think it contains a lot of ingredients that your body doesn't need.
5. RSP Quadralean Non-stim
RSP Quadralean Non-stim has 4 ingredients that they claim are key for weight management -- CLA, L-Carnitine, Grains of Paradise, and Green Tea Extract.
I had never seen Grains of Paradise in a fat burner before, so I did some research into what it was all about. It's an herb from the ginger family. There aren't a lot of studies on humans, but studies on rats show that it helps with weight loss.
One issue I have is that one serving is equivalent to 3 capsules. It seems like a lot of pills, but each bottle contains 50 servings. So even though you need to take 3 capsules, this bottle will last you a while.
6. Kaged Muscle Clean Burn Stimulant Free
Kaged Muscle has its own fat burner called Clean Burn. It's formulated with the best ingredients to support thermogenesis (the process of increasing body heat). Ingredients include Capsimax (pepper extract), Green Tea Extract, L-Carnitine, and Gymnema Sylvestre Extract.
L-Carnitine helps burn fat into energy, and Gymnema Sylvestre Extract helps maintain blood sugar levels, blocks sugar absorption, and reduces sugar cravings. Both are key to helping you achieve your weight loss goals.
It's one of the best options for athletes since it helps melt fat without losing any muscle mass. This fat burner has also been third-party tested to prove there are no banned substances in their products.
Each bottle has 90 servings. The recommended dosage is 2 pills, 3 times a day, which seems a lot for some. One bottle will last you one month based on their recommendation. You may not need to take that much, so you can adjust your intake as needed.
7. Evlution Nutrition Lean Mode Stimulant-Free
Evlution Nutrition has ingredients commonly found in other non-stimulant fat burners like CLA, Acetyl L-Carnitine, and Green Tea Extract. The two ingredients that set this formula apart are Green Coffee Bean Extract and Garcinia Cambogia Extract.
Green Coffee Bean Extract supports fat burning and metabolism. They use decaffeinated green coffee beans, so you don't have to worry about getting stimulants from them.
Garcinia Cambogia Extract is from a tropical fruit called tamarind. The only information that the company gives about this ingredient is it contains a premium 60% Hydroxycitric Acid (HCA).
I did some research, and HCA appears to block an enzyme that creates fat. It also suppresses feelings of hunger. Even though it seems that this will help with weight loss, there haven't been any studies to prove it .
The bottle says you need 3 capsules per serving. This seems like a lot of pills to take in one day. Especially since they recommend taking 2 servings twice a day for the best results. One bottle has 50 servings, so one bottle may barely last a month. If you only take one capsule a day though, then it can be of great value.
8. Beverly International Quadracarn
Beverly International claims that their Quadracarn formula helps regular users with enhanced fat loss, lean muscle, circulation, vascularity, energy, mood, and more. Those are high claims, so let's take a look at the ingredients to see if it's true.
The company claims that having 4 different varieties of carnitine will help you get the most results. It will help build muscle, burn fat, and build endurance. The 4 types are N-acetyl-L-carnitine, L-carnitine, L-carnitine-L-tartrate, and propionyl-L-carnitine.
The formula also has Gymnema Sylvestre, which helps with suppressing sugar in your system. People love this unique formula since it helps them lose body fat and tone their muscles.
It's an excellent choice whether you're a fitness competitor or merely wanting a healthier physique. It can also help with anti-aging.
You have to be pretty dedicated to taking this supplement. One serving is 3 tablets, and to achieve maximum results, they recommend taking it 3 times on workout days and twice on non-workout days. This means that you will be taking as many as 9 tablets in one day. Beverly International says this is necessary to get the full amount of carnitine that your body needs.
9. Xtend Ripped Non-Stimulant Cutting Formula
This isn't strictly a fat burner. It's more of a BCAA supplement, but it does contain fat-burning ingredients like cayenne. This might be an excellent product for you if you are looking to get essential amino acids while also promoting weight loss.
Besides containing the necessary BCAAs for muscle growth and strength, it also contains other fat burning ingredients such as L-Carnitine Tartrate and Capsimax. Both of which help turn fat into energy for your workouts.
It's recommended to take two heaping scoops mixed with liquid every day for the best results.
It has 4 flavors; Blueberry Lemonade, Orchard Splash, Strawberry Kiwi, Watermelon Lime. I've heard great compliments about the flavors, especially the blueberry lemonade.
The nutrition label says it contains milk, which makes it not allergy-friendly. It also contains artificial colorings, so it's not entirely wholesome.
10. No-Stim Non-Stimulant Fat Burner
No-Stim says their product is different because it also supports thyroid health in addition to suppressing your appetite and boosting metabolism.
It does this by using ingredients like selenium, tyrosine, and iodine. The ingredients they use to suppress feelings of hunger are the herbs Hoodia Gordonii and Saffron extract.
This is a product for anyone, including adults in their 40s or 50s looking to get themselves back into peak shape.
The thyroid boosting supplements combined with the appetite-reducing ingredients ensure that your metabolism doesn't slow down even if you reduce your caloric intake.
They recommend taking two pills a day. An entire bottle is good for a month based on serving suggestions. However, it can be an expensive product compared to other options.
What ingredients should a stimulant-free fat burner have?
Here's a quick breakdown of the most common ingredients found in stimulant-free fat burners and their benefits.
Green Tea Extract
Green Tea Extract is a concentrated form of green tea. It has gained popularity because it contains epigallocatechin gallate or EGCG. EGCG is a property known for decreasing fat synthesis and increases the breakdown of fat.
It also contains an antioxidant known as catechins. This antioxidant helps block out an enzyme, which leads to a higher heart rate and body temperature. It leads to the body burning calories faster.
For maximum results, you should try to find a fat burner that has 250-500 milligrams of green tea extract. It's a lot easier to take green tea extract instead of regular green tea. Otherwise, you would take 3-5 cups of green tea per day to get the same amount.
Forskolin is pretty new in supplements. However, so far, it's proven to have great results with fat burning.
One study on Forskolin shows that it decreases body fat percentage while increasing lean muscle .
This is an overall favorable change in body composition that is great news for people looking to lose fat and gain muscle.
The same study also shows that it can also help bone health and testosterone levels. Subjects had a change in bone mass, and overweight men had their testosterone levels increase.
Forskolin helps people burn away fat but not muscle.
Maintaining a healthy testosterone level is vital in maintaining muscle mass and burning more calories.
Some other ingredients that are popular for stimulant-free fat burners and weight loss supplements are capsaicin (chili pepper extract) and L-Theanine.
What ingredients should I avoid in a stimulant-free fat burner?
I would recommend trying to avoid any fat burner that contains filler ingredients or anything artificial. You should take the time to research each ingredient to determine if it's scientifically-proven to support weight loss. Many fat burners claim that they help people lose weight but don't have the science to back it up.
Why should I choose a stimulant-free fat burner over those with stimulants?
You should choose a stimulant-free fat burner over those with stimulants because it gives you the benefit of not getting a caffeine-crash.
Stimulants like caffeine can increase the functions of your body, like heart rate, metabolism, and improved awareness. However, it could cause issues like heart problems or high caffeine tolerance, when taken in large doses.
Some people can build a tolerance over time, but you may prefer to just avoid stimulants altogether.
Some common side effects of stimulant use include:
Stimulant-free fat burners are the answer for those wanting to avoid stimulants but still get a boost for burning fat.
Other recommended fat burners for you:
When should I take a stimulant-free fat burner?
I would recommend taking your stimulant-free fat burner first thing in the morning. Ideally, 30 minutes before breakfast. This will help give your metabolism a kick after slowing down during the night. By taking it first thing in the morning, it will help achieve a better workout.
What are the side effects of stimulant-free fat burners?
Even though the removal of stimulants will decrease the side effects you get, some people may still experience negative symptoms. An upset stomach is a common side effect. If this happens to you, try taking your supplements with food. Another solution is to avoid taking multiple supplements at the same time. They may not react well with each other. Try to space them out with food in between.
Our #1 Recommendation Is...
Don't be scared to try a fat burner. There are plenty of supplements that are good for you and also help you achieve your body goals. I would recommend trying the Performance Lab Fat Burner.
It's highly praised, and the product ingredients are top-notch like Forslean, Capsimax, and BioPerine. It does more than just give you nutrients; it also helps with thermogenesis, which is the body's efficient fat-burning process.
