Written by Isaac Robertson

All clients I meet ultimately have one thing in common: they have fat loss goals that they are somehow struggling with.

It’s the same for performance athletes who are trying to cut down to the lowest possible BMI, as it is for people in their 50s who have ended up neglecting health and fitness for too long and need to shed some pounds.

The problem is that our bodies like to hold onto fat reserves. It’s an evolutionary concept where fat reserves were critical to avoid starvation when food becomes scarce. But scarcity and long fasting periods are pretty much a thing of the past.

While diet and exercising are the two most important factors for fat burning, there are numerous supplements that can help you achieve your goals fast.

On this page, I will be showing you my research results into stimulant free fat burners, which are ideal for anyone that is over-sensitive to caffeine.

1. Editor's Choice: Performance Lab Fat Burner

First on our list of stimulant free fat burners is a product that the entire team here has agreed to place in the number 1 spot and this was also backed by a dietitian I regularly work with.

We all liked that there is no confusion over what’s in this weight loss supplement, as the company has kept it simple and doesn’t hide behind some proprietary nonsense.

Many users online point out that it works well to support fat loss training thanks to the cayenne and forskolin ingredients. But it does one extra thing that convinced us all.

Performance Lab Fat Burner


  • Cayenne pepper works as a thermogenic
  • Forskolin improves hormonal balance to trigger fat metabolism
  • Contains HMB from branched-chain amino acids to retain muscle mass
  • check
    Plant-based vegan-friendly product


  • Bulk buy savings could be a bit better

By adding an ingredient called HMB, which is derived from BCAAs, you can reportedly diminish the risk of muscle wasting during a fasting period.

It’s not the cheapest product, but you get what you pay for. And here you get an all-natural, plant-based formula. Some better bulk discounts would be nice though.

2. LeanBean

One problem that most women will have is that fat burning supplements are often formulated to support the larger doses needed for men. So, if you’re female and sick of trying to figure out what smaller dose you need to take, then check out LeanBean.

So many people on Facebook urged me to research it because they had been using it successfully for quite a few months. It’s completely stimulant-free, so if you need to take something later in the day or you’re just sensitive to caffeine, then it’s a solid choice.



  • All natural ingredients with no harmful chemicals
  • Many reports of effective use without any stimulants
  • Positive impact on mental and physical energy
  • check
    Claims to work well as an appetite suppressant by adding garcinia cambogia


  • Only available on the official website

What stood out for me, though, was the added garcinia cambogia. Many people turn to this fruit extract to burn fat, but from my own experience, it works much better to suppress hunger cravings.

It has 3000mg of Glucomannan and it’s approved for weight loss in the European Union. It’s also recommended to take 6 capsules per day: 2 during breakfast, lunch, and dinner, respectively.

Certainly worth a try for all women reading this.

3. Transparent Labs Fat Burner

The next fat burner without caffeine comes from Transparent Labs, and I’ve been a fan of their products for quite a while now. This was the first time I tried their non-stimulant fat burner, but I did find the results were positive.

In the majority of comments I reviewed, people did find that their cutting phases more effective than before taking these.

My dietitian pointed to the L-Carnitine, which is a vital part of getting fatty acids to muscle cells where they are used as raw energy.

Physique Series Stim-Free


  • Good L-Carnitine dose to speed up fat processing
  • A simple formula of 6 ingredients that are backed by science
  • Added vitamin B12
  • check
    No artificial crap added as sweetener, flavor, or preservative


  • You need to take 4 capsules daily for optimum effect

It’s great that the company prides itself in publishing all the details about their products, as it just takes the guesswork out of it. Just be prepared that you will need to take 2 pills twice daily. 

4. Lean XT

This is a product that Tracy here in the office recommended as she had seen a lot of positive results with her female clients. And having read through a few hundred reviews and forum comments, it does seem to work well, especially to keep hunger at bay.

If you’re doing a calorie-restricted diet and struggling with eating less, then this can make quite a difference.

It also has a decent amount of green tea extract, which can help to burn fat, but more importantly, it will help with detox and getting rid of free radicals.

Lean XT


  • Many positive comments about suppressing food cravings
  • L-Carnitine speeds up fat loss
  • Contains green tea extract for detox 
  • check
    Claims to reduce your body’s ability to store fat


  • Limited bulk discount availability

I also saw a lot of comments about it helping to maintain weight by reducing your ability to create new fat storage. The only downside with this product is that discounts are not readily available when you buy in bulk.

5. EVL Nutrition Lean Mode

OK, here’s the final product I would recommend, and from the reviews I’ve read, it seems like it still helps to give you some mental focus and motivation even without the stimulants that are so common in other supplements.

A lot of people also commented that it works well to avoid hunger cravings that you can get during fasting periods or low-calorie diets.

Combine all that with CLA, and you get more fat burning to increase your energy output. And you can take advantage of that during training to work hard on some more lean muscle mass.

EVL Nutrition Lean Mode


  • No jitters but you still get a good mental boost
  • Some positive comments about hunger suppression
  • Helps provide more energy for workouts
  • check
    Contains CLA which has been shown to boost metabolic rates


  • You need to take 3 capsules for full daily serving

It’s not our top pick, and if you’re not on a strict budget, then I would suggest you try the Performance Lab Fat Burner above. But it’s still a good option that will work better than not taking any supplement at all.

What Does Stimulant Free Fat Burner Mean?

Stimulant free fat burner means a supplement that doesn’t rely on some of the common stimulants like caffeine (more on this in the next section).

But what’s the problem with caffeine? Isn’t it effective?

Yes, it absolutely is, and countless clinical trials have shown that it works as a potent thermogenic. But, it also has a stimulating effect on the brain, which is why so many of us simply cannot function without a coffee first thing in the morning.

For me, it’s a must, but Tracy here at the office would end up acting like Tweak from Southpark, so it’s something she needs to avoid in all her supplements. 

What Type Of Stimulants Should You Avoid? 

If you know that you’re sensitive to the effects of a coffee or strong cup of tea, you should always look out for the following on the nutritional label. 

1. Caffeine


This is by far the most common, and you’ll see it referenced as either natural or anhydrous.

Both have the same effects, but they are produced in slightly different ways.

Natural caffeine is extracted from beans in a very similar way as a cup of coffee would.

However, anhydrous is extracted from seeds and leaves, which creates a very concentrated powder. (1)

Caffeine anhydrous is made from the seeds and leaves of coffee plants. The word “anhydrous” means “without water.” After harvesting, caffeine is extracted from the plant matter and dehydrated. This produces a highly concentrated caffeine powder.

2. Taurine

This is something you’ll find less often, and it’s actually more common in energy drinks. (2)

But some producers will market their formulas as a non stimulant weight loss supplement, and then add in some taurine.

The real potency of this amino acid is still not clear, but I generally tell my clients to stay away from it.


What Effects Do Fat Burners Have?

Effects On Non Stimulant Fat Burners

I could say that they aid your metabolism to shed some flabby stuff and end this section, or I could bore you with an essay on what happens in your body. But, I’ll do neither and just give you a quick summary.

1. Thermogenesis

This is a metabolic process where your core temperature is slightly raised. And in order to achieve this, you have to burn off some energy. Once the readily available blood glucose has been diminished, you will start to go after fat reserves. (3)

The result is an effective way to get more out of your daily diet and exercise routine.

2. Appetite Suppression

It’s no secret that in order to lose weight, you have to eat less and healthy. That often means that you need to go on a net negative calorie diet, and that can often lead to hunger pains and cravings.

By filling you up or suppressing certain hunger hormones, fat burners can make it far easier to stick with your diet.

3. Reduced Ability To Store Fat

This is something that’s often overlooked, but being able to maintain your weight is just as important as losing it. Many options these days will include stuff that will inhibit your body’s ability to transform excess calories into fat.

The result is less chance of constant weight fluctuations.

4. Increased Training Performance

Of course, all that energy that gets released has to find a home. If you time your intake well, then you can also achieve some extra energy for your training. And if this isn’t enough, then why not try a product that contains creatine as well?

When Should You Take Fat Burners?

The great thing about caffeine free fat burners is that you don’t have to be as careful about their impact on your ability to sleep at night. I generally recommend options that are spread out over 2 to 3 doses a day, like LeanBean and PowHer.

This supports your metabolism better as it keeps it firing at a higher rate from morning to evening. If you’ve never taken these before, then aim to take them with your meals. Some of them can be a bit tough on your stomach.

What Natural Ingredients Work As Fat Burners? 

Natural Ingredients

For a long time, the health and fitness industry just focused on telling people to load up on some whey protein and reduce carbs and calories. But science has advanced, and there are a few more things that you should look out for.

1. Conjugated Linoleic Acid

It’s difficult to pronounce, so let’s just call it CLA as it’s known in the nutrition industry. There has been some controversy over it, but increasing numbers of studies have revealed a link to weight loss. (4)

2. Forskolin

Sourced from the roots of an Asian plant, some studies have revealed a link to it being able to increase the amount of stored fat that is released. (5) How effective it actually is hasn’t been quantified, but as it’s such a natural ingredient, it has the advantage of no known negative impacts.

3. L-carnitine

This amino acid is believed to work by helping to transport fatty acids that have been broken down from fat storage. The more that can be transported to muscle cells, the faster you can melt away fat.

4. Green Tea Extract

If you don’t like drinking green tea like me, it doesn’t mean that you don’t have a way to take advantage of this modest fat burner and potent antioxidant. In a concentrated extract form, you can get a big boost to your overall health from a very natural tea.

Final Thoughts: Which Fat Burner Should You Pick?

So, after endless hours of reading online reviews, interviewing dietitians and having some of the team test the products, we did manage to come to a conclusion as to which one deserves the top spot from these best non stimulant fat burners.

We all kept going back to Performance Lab. It strikes a great balance between melting away the flabby stuff and helping to build and retain some muscle tissue as well. If you haven’t tried it before, then I highly recommend placing an order today.

And remember to let us know how your experience was.
