Are you looking to try a fat burner for the first time? Worried about the jitters and choosing a supplement that’s got a large amount of stimulants in it?

If you’ve never used a product like this before then we know that there can be mind-boggling amount of information online, making it impossible to make a decision.

Many supplements out there use large amounts of pure caffeine or a substance called Caffeine Anhydrous in order to help boost your metabolism and lose weight.

Whilst there’s no doubting the weight loss credentials of this well-known substance, for some, a fat burner packed with stimulants can be a little too much.

Fortunately, our team of researchers have done the leg-work for you in order to come up with a list of the most effective, caffeine-free fat burners out there.

We’ve had a look at how these products work, what ingredients are included and the things customers have been saying about them.

But first, let’s take a look at how a top fat burner can help you lose fat and what you should be looking for when choosing one.

How do fat burners work?

Now, you may have heard a lot about natural supplements called fat burners. But how do they actually work?

Essentially a good quality fat burner works in a few different ways:

1) Firstly, all good fat burners include ingredients to speed up your metabolic rate. This ensures you are burning calories all day long through a process called ‘Thermogenesis’.

2) Secondly, the best supplements in this category should have a significant impact on appetite. As you’ll know one of the best ways to block fat production is to avoid consuming excess sugar and snacks.

3) Third up is hormonal health. It’s a little-known fact but for many people an overproduction of Oestrogen can cause obesity. Fortunately, there are ingredients out there that have been shown to counteract this.

4) Finally, all good fat burners should improve energy and endurance.

It’s worth remembering that fat burners don’t do all the work for you, but rather they improve your body’s natural ability to burn fat by delivering the best ingredients in the most effective doses.

The best ingredients that won’t give you the jitters

When it comes to fat burning, you’re most likely to suffer jitters if you choose a fat burner that includes synthetic stimulants or large amounts of pure caffeine.

Here, we’ve listed some of our favorite ingredients that won’t leave you feeling unwell:

• Cayenne Pepper – Cayenne Pepper is a spice often found in Chilli’s. It’s one of our favorite fat burning ingredients, it works by speeding up your metabolism but also by reducing your appetite between meals.

• Turmeric – Another powerful spice that blocks fat production in a number of different ways. It’s particularly effective at destroying brown fat cells as well as blocking Oestrogen, something that’s particularly helpful if you’re female and looking to lose weight.

• Glucomannan – Like we said all good fat burners should be able to effectively target your cravings, this plant extract contains high levels of Konjac Fibre making it brilliant at reducing your appetite.

• Raspberry Ketones – The substance responsible for making Raspberries red. This substance has been shown to help the body produce more of the fat burning hormone Adiponectin.

• Green Coffee Extract – The active ingredient here is actually something called Chlorogenic Acid which has been proven to reduce fat absorption and improve endurance.

• Garcinia Cambogia – Shown to increase Serotonin levels and reduce appetite and cravings.

• Black Pepper – We always like to see this ingredient in a supplement of this type, that’s because it improves your body’s ability to absorb other fat burning compounds like Turmeric.

• Green Tea Extract – Green Tea is an all-time favorite when it comes to shredding the pounds. Green Tea’s success comes from something called Cathechins, they’re an antioxidant that turn on the fat burning hormone Adiponectin.

Avoid proprietary blends

One of the biggest considerations when buying a top fat burner is safety, over the years there’s been plenty of supplements that have fallen foul of this. One things we never like to see is a proprietary blend.

This is where a manufacturer blends together lots of different ingredients and lists the total amount of this blend on the label.

Unfortunately, this means that the individual doses of each ingredient are not included, something that is a particular problem if the product includes large amounts of caffeine.

The best fat burners without caffeine

All that’s left to do now is to give you a list of our favorite fat burners that are low in stimulants and safe for those who are sensitive to caffeine.

The main criteria for these products was that they promoted all round fat burning through their use of spices and natural plant extracts. None of these fat burners include pure caffeine extract or Caffeine Anhydrous.

1) Leanbean – Best for Women

Product website:


Number one on our caffeine-free fat burner list is Leanbean. It’s actually a female only formula made by supplement firm Ultimate Life.

The fact that Leanbean has been specifically developed for women means that the makers have purposefully avoided using stimulants like Caffeine in the product.

Instead, Leanbean uses solid quantities of a number of different spices and plant extracts to help you slay troublesome fat.

Key ingredients

Leanbean includes Cayenne Pepper to boost metabolism and suppress your appetite after a meal.

Also present is Turmeric, This super spice attacks fat from a number of different angles. It’s known to be particularly effective at blocking oestrogen, making it a great ingredient for women looking to burn fat.

Other key ingredients included Glucomannan, which is famed for its miraculous ability to make you feel full between meals helping you cut down your sugar intake.

There’s also solid doses of Green Tea and Raspberry Ketones, both of these have been shown to switch on fat burning hormone Adiponectin.

Finally, Green Coffee is included to support thermogenesis and improve athletic performance.

Key benefits

• Stimulant free ingredients that target fat and cellulite
• Formulated and dosed for women
• Improved beach body confidence
• No side effects
• Vegan friendly

How to take

One month of Leanbean includes 120 capsules. The suggested dose is 1 tablet taken four times a day. It’s recommended that you take them at evenly spaced intervals to ensure the ingredients are working for the full 24 hours.

What do the reviews say?

Leanbean is quite a new product. So far, it’s received some solid reviews on the internet and social media.

We found strong testimonials on the brand’s website as well as a number of successful reports done by leading fitness bloggers.

leanbean result

Examples of this included one user who said they’d been thrilled with the results, despite having previously been nervous of fat burners.

Another customer said they’d loved how toned and muscular they felt since taking Leanbean.

And another user said Leanbean had kick-started their new lifestyle and driven them to lose a significant amount of weight.


There’s no denying that Leanbean is one of the pricier options on the market. That being said they do offer some great deals when you buy multiple boxes.

One month’s supply of Leanbean starts at £35 / $59. If you’re really serious about cutting down then you might want to give their Bikini Body Bundle a try.

This is basically four months of Leanbean for the price of three. You also get a free workout guide included too. You can get this deal on the official website.

2) Performance Lab SPORT Fat Burner – Best for Men

Product website:

Performance Lab Sport Fat Burner

The second product on our list which we’ve also given a five-star rating is the SPORT Fat Burner by Performance Lab. This is our top pick for men looking for a fat burner without Caffeine.

Performance Lab is the latest brand of supplements to be released by industry veterans Opti-Nutra, and the SPORT Fat Burner is their main fat-loss product.

Like all of the products on this list, it doesn’t contain any Caffeine at all, and Performance Lab have really produced a top quality fat burner supplement. Let’s take a look at why.

Key ingredients

Performance Lab SPORT Fat Burner uses Cayenne Pepper to help get your metabolism firing. Cayenne is also a great ingredient because it doubles up as an appetite suppressant, which can help make sticking to your diet easier.

It also uses Coleus Forskohlii which is believed to help minimize body fat while maximizing lean muscle growth.

Also present is HMB, which is known for helping to help trigger muscle-building and muscle recovery systems in your body that can support lean muscle mass in conjunction with training. These effects are especially mazimized if you’re performing fasted training.

Like all good supplements, SPORT Fat Burner also uses Black Pepper Extract to help increase the absorption and make for a more effective product overall.

Key benefits

SPORT Fat Burner has been specifically formulated to help burn more fat than with exercise alone, especially during fasted training.

That means that if you hit the gym in the morning while in a fasted state (having not eaten anything) then this is the fat burner supplement for you.

• Stimulant and Caffeine free
• Enhanced absorption
• Maximize fasted training
• No side effects
• Vegan friendly

How to take

Each bottle of SPORT Fat Burner contains 60 capsules. The label says that for best results, you should take 2-4 capsules 15 minutes before starting your training session.

What do the reviews say?

Because the Performance Lab range is a relatively new one, there’s not a great deal of feedback about this product available online at present. However, we’ll update this section when more people have posted their feedback.


The Performance Lab SPORT Fat Burner is a high quality, safe and natural fat burner without Caffeine or stimulants.

It contains some of the best natural fat burning ingredients without any stimulants, and is delivered in one of the most innovative ways we’ve ever seen.

One bottle of SPORT Fat Burner costs $50 / £40 – but Performance Lab do offer big discounts if you buy more than one bottle at a time. If you’re serious about cutting fat, you’ll want to commit to using this product for at least two to three months.

3) PhysiqueSeries Stim Free

Product website:

PhysiqueSeries Stim Free Fat Burner

Next up is a product by Transparent Labs. Their PhysiqueSeries Stim Free Fat Burner is one of the few products on the market that is targeted to both men and women and doesn’t contain any stimulants such as Caffeine.

Transparent Labs have built their brand around the concept of always sharing the full ingredients used in their supplements.

Key ingredients

PhysiqueSeries Stim Free uses some good proven fat burning ingredients without the stimulants.

The main good ingredient used is Cayenne Pepper. As we know, Cayenne is great for boosting metabolism and can also have appetite suppressing effects at the same time.

It also uses Rhodiola Rosea. Although we usually associate this ingredient with pre workout supplements, it’s a good inclusion here. It’s a herb that can help to boost cognition and overall mood.

There is also a dose of 5-HTP. Although this is not shown to help with fat loss, there have been some studies which suggest that it could help to suppress appetite while dieting.

Key benefits

• Stimulant free
• Formulated for both men and women
• Uses Cayenne Pepper to boost metabolism
• Rhodiola Rosea to improve mood and cognition

How to take

You take two capsules with a glass of water, twice daily, 30-60 minutes before meals.

Each bottle contains 120 capsules, which is a month-long supply.

What do the reviews say?

This product has very strong reviews on the official Transparent Labs website, although that’s probably no surprise.

There were lots of people who clearly love this product. One person said it was the best “clean” fat burner they had found.

Someone else said that they already started noticing fat loss after just one week, although we’re not sure how accurate that is, as we all know burning fat takes time!


PhysiqueSeries Stim Free is a decent fat burner if you’re looking to shed the pounds without the stimulants. The only negatives are that you can only buy it from the official website, and they could have used a natural appetite suppressant such as Glucomannan.

4) Complete Thermogenic Stimulant Free

Product website:

Complete Thermogenic Stim Free

Next on our list is the Complete Thermogenic Stimulant Free by Bulk Powders.

Bulk Powders are a UK-based supplements company known for their affordable range of products, and this is the stimulant free version of their main Complete Thermogenic product.

Key ingredients

Like Leanbean, the main ingredient in this fat burner is Green Tea, but they use a ‘caffeine-free’ version, which is great news. Green Tea is one of the best natural fat burning ingredients around because of its potent thermogenic properties.

Complete Thermogenic Stimulant Free also uses L-Carnitine. This is a widely researched amino acid that can help to fight fatigue. Although it’s not going to help directly with fat burning, it will help to keep you feeling energized, which is good news.

It also uses BioPerine, which is essentially a branded form of Black Pepper Extract. This is good because it’s been shown to increase the absorption of the other ingredients in supplements.

Key benefits

• Uses Caffeine Free Green Tea
• Contains Black Pepper Extract
• L-Carnitine to reduce fatigue

How to take

Each bottle of Complete Thermogenic Stimulant Free contains 180 capsules.

The directions say that you should take a whopping six capsules spaced evenly throughout the day, ideally 30 minutes before food.

On training days, you should take 2-4 capsules (of the 6 capsule daily intake, not in addition) 30 minutes before exercise.

What do the reviews say?

This seems to be a well-received product. It has a 4.5 star rating out of 5 on the official website.

However, one customer complained that some of the capsules had broken in transit to leave powder at the bottom of the tub.

Someone else said they loved the product and called it “fantastic” because it helped them to maximize their fat loss.


This is a decent stimulant free offering from Bulk Powders. That said, they could have used some other stimulant free ingredients such as Cayenne Pepper and Glucomannan to make this a top of the range supplement.

5) Lean Mode by Evlution Nutrition

Product website:

lean mode

Lean mode is number four on our list. It’s a stimulant free fat burner manufactured by Evlution Nutrition.

Lean Mode claims to use 5 ‘stim free’ modes of action to support metabolism, mood and fat burning.

Key ingredients

Like our number one pick, Lean mode includes some of the best fat burning ingredients without resorting to having to include lots of caffeine.

In particular, we like the inclusion of low stimulant options like Green Coffee Bean, Green Tea Extract as well as Garcinia Cambogia. All of these ingredients have been shown to aid weight loss without making you feel unwell.

Key benefits

• Stimulant free ingredients
• Improved metabolism
• Includes Green Coffee

How to take

Each bottle of Lean Mode contains 50 capsules. The recommended daily dose is three capsules meaning one bottle will last you around two and a half weeks.

What do the reviews say?

We looked online and in the main found good reviews, with just a couple of negative ones.

One customer we came across said they’d seen significant change and they’d be excited to recommend it to friends, another said that it helped them control their appetite and lose weight.


All things considered, we think this is a good stim-free choice. It contains some nice fat burning ingredients. If we’re being ultra picky we’d have to say the formula isn’t quite as comprehensive as our number 1 pick.

Wrapping thing up – Our final thoughts

There we have it, we’ve picked out the best fat burners that don’t include caffeine.

As we always say, choosing a good fat burner is just one part of the process, to really succeed you’ll need to keep up with your training and eat the right things.

It’s all about giving your body the fuel it needs to turn into a fat burning machine.

When conducting our research, we found that caffeine free fat burners are becoming more and more popular, so it was pleasing to see an increase in non-stimulant options coming onto the market.

For the most effective Caffeine free fat burner we’d have to go with Leanbean as our pick of the bunch. It’s got the best quality ingredients in solid doses, all backed up by consistently good reviews from users.
