Adding a tried-and-tested fat burner to your health and fitness regimen can make a big difference in helping you get lean.

UPDATE: We’ve updated this article with the latest information and products for 2018. Leanbean and Instant Knockout are the best fat burner for women supplements available right now. We’ll continue to review and update this article during 2018.

Summer is here, and there’s no better feeling than stepping onto the beach on the first day of your holiday, feeling the warm sand underneath your feet and noticing that you truly feel proud of your body.

It’s what we all want, but sometimes it can feel as though there’s something stopping us from being able to really get the look we’re after.

You’re not alone, and better still, there’s a solution!

First things first, although some of the fat burners on sale these days are sold as ‘magic pills’ to help you lose weight, the truth is that you simply won’t be able to reach your fitness goals if your exercise routine and diet is not on point.

That being said, adding a top fat burner to your regime can often end up being the ‘missing link’ in helping you shed those final few areas of stubborn fat that you just wish would melt away.

Now, you could be forgiven for thinking that most of the fat burners on sale these days are designed specifically for men, but that’s not the case at all!

We’ve done some digging to unearth the best fat burners for women in 2018, paying particular attention to the ingredients in each of these products and how they work.

But do fat burners really work?

Well, luckily for you, we’ve also broken down some of the key ingredients you should look for when searching for the best fat burner and how they help you get lean.

What to look for in a fat burner

Firstly, you should only be considering products which contain all-natural ingredients. With the health and fitness industry booming, it can be difficult to pick out the best quality products. Fortunately, we’ve done the hard work for you below.

There are some key ingredients that all good fat burners should contain. These include:

Green Tea Extract
Green Coffee Extract
Cayenne Pepper
Black Pepper Extract

Most of the products we’ve picked below contain a good amount of caffeine, so it’s generally best to take them early on in your day so that they don’t affect your sleep and downtime.

How do fat burners work?

There are three main ways in which the best fat burner tablets work – for both women and men.

1) The best fat burners nowadays are usually designed to increase your metabolic rate. What does that mean? In short, you’ll burn more calories than you would do normally.

2) The tablets also typically contain stimulants to help boost your energy levels. This can help you stay active and burn more calories.

3) Some of the best fat burners also contain natural ingredients which have been shown to help you control hunger cravings, making it easier for you to stick to your diet.

Best fat burners for women

So, with the science out of the way, here’s our definitive guide of the best fat burners for women on sale right now.

=1) Leanbean

Product website:

Leanbean fat burner

Leanbean includes generous quantities of some of the best fat burner ingredients

Leanbean is a fat burning supplement that has been formulated and dosed for women. We’ve rated it our number one fat burner in the female category.

Leanbean was created by Ultimate Life, a specialist in female gym supplements. It’s manufactured in both the UK and US and is available to buy worldwide.

The product was initially designed for fitness models and female athletes looking to sculpt their bodies before a big competition.

We took an in-depth look at this product, and found that it’s Leanbean’s ingredients as well as the science behind them, that make it one of the most effective fat burners money can buy.

And after analysing reviews and testimonials online we also found this product received consistently strong feedback amongst users.

What’s in it?

Leanbean includes solid quantities of some of the best fat burning ingredients.

The main difference with this supplement is that it has been created specifically for women, and this has meant certain ingredients have been added and doses have been tweaked to make it female friendly.

In particular, Leanbean includes ingredients such as Turmeric, which has been shown to counteract the negative effects of excess Estrogen in females. This is important, as various studies have shown that high levels of Estrogen are consistent with high fat storage in women.

Leanbean before and after

The other key benefit of Leanbean is that it boosts metabolic rate to help you burn calories whilst not going overboard on stimulants.

Instead, it includes caffeine from natural sources such as Green Tea and Green Coffee extract, whilst utilising powerful spices like Cayenne Pepper too.

These all work together to help you boost your metabolism and burn fat through a process called thermogenesis, helping you to shed the pounds without the inconvenience of unpleasant side effects.

Leanbean also includes a solid dose of Glucomannan – also known as Konjac fibre – this natural plant extract swells in your stomach to keep you feeling full and prevent you from overeating.

How to take it

Each bottle of Leanbean contains 120 capsules and will last you a month. This supplement has been designed to be taken four times a day at evenly spaced intervals, to promote 24-hour fat burning.

Unlike other fat burners on the market, Leanbean also includes Turmeric

Any negatives?

As with our other favourite supplements, this is definitely one of the more premium-priced products around, it’s also only available from Leanbean’s website, so you won’t be able to find it in the shops or on Amazon.


Leanbean is a great fat burner with quality ingredients and consistently high customer feedback, which is why we’ve made it number one on our list.

A one-month supply will cost you £35 or $59. They also have promotions available on multi-box purchases including a free workout guide.

Like any top fat burner, you’ll need to pair it with the necessary training to see very best results. If you’re looking for perfection like a top athlete, we’d suggest following a longer course of at least 2-3 months.

=1) Instant Knockout

Product website:

Instant Knockout

Instant Knockout is one of the most popular supplements for burning fat

Instant Knockout is one of the most popular supplements for burning fat.

We rate it really highly, which is why we took the unusual step of making it joint first in this category. This decision was based on the product’s quality ingredients and the fact that women have reported great results when adding it to their regimes.

Instant Knockout is produced by specialist supplements company Roar Ambition and has a great blend of all-natural ingredients to help you get lean and shed the pounds.

The main section of the website appears to be geared towards men, but it also has a special section for women and how the supplement is designed to work for both genders.

Instant Knockout contains ingredients to help your body burn more fat

What’s in it?

Instant Knockout contains a great blend of some key natural ingredients to help your body burn fat. One of those is Green Tea, which can help burn fat in three different ways.

Another key ingredient is Cayenne Pepper, which is known for boosting your metabolism and helping to suppress appetite.

Each tablet also contains Green Coffee Bean and Glucomannan as well as Piperine, which has been shown to block the formation of new fat cells. Zinc and Chromium are two other natural ingredients.

There are lots of Instant Knockout success stories on social media and other websites

Any negatives?

It’s a premium-priced product, so it may not fit into everyone’s budget, and you can currently only buy it on the official website.

The capsules in this supplement are made from gelatin, meaning that it’s not suitable for vegetarians.


This is one of our prime picks in the best fat burner for women category because it contains a good blend of some of the best natural ingredients proven to help burn fat.

The metabolism-boosting ingredients make for a fantastic blend to give your body all of the fuel it needs to start burning fat quicker than ever.

It’s a little bit on the pricey side but they do offer discounts for multi-box orders.

2) Protein World Fat Metaboliser capsules

Product website:

best fat burner uk

Next on our list is best-selling Protein World’s fat burner pill.

The Fat Metaboliser capsules (which used to be called Fat Melter capsules) combine a healthy dose of some great ingredients to help you shake off those stubborn areas of fat which don’t seem to want to budge.

Protein World is a UK-based supplements company famous for its Slender Blend protein powder and with a strong brand. This particular product seems to be more aimed at women than men.

What’s in it?

This product has a good blend of some key ingredients when it comes to helping burn fat.

Each tablet contains a mixture of Caffeine, Green Tea Extract and Vitamin B6, as well as Guarana to help keep your metabolism firing.

It also contains Choline, which has been shown to help contribute to lipid (fat) metabolism.

Any negatives?

It contains quite a lot of caffeine (126mg per capsule) and that may be too much for some people.

It’s also another premium-priced product so may not fit into everybody’s budget.


This is a strong product from a reputable UK-based supplements company. It contains a good blend of some proven fat burning ingredients, making for a good all-round natural fat burner pill.

3) Grenade Thermo Detonator

Product website:

fat burners uk

Next up is Grenade Thermo Detonator.

On first glance, it may appear that this fat burner is aimed mainly at men, but the website says it has been specifically designed for both men and women.

Let’s take a look at why this popular fat burner is also a good option for you.

What’s in it?

Thermo Detonator contains a great blend of Green Tea, Bitter Orange Powder, Caffeine, Cayenne Pepper, Phenylalanine and Green Coffee to help you burn fat more quickly.

Interestingly, the website recommends that you take the pills on an empty stomach to get the full fat burning effects.

Any negatives?

We’re a little bit disappointed that it doesn’t contain Black Pepper Extract (Piperine) because it has been shown to help your body get the most of each individual ingredient.

Again, it’s also a little bit on the pricey side.


4) Myprotein Thermopure

Product website:


Next on our list is Myprotein’s top fat burning pill – Thermopure.

We’re big fans of Myprotein’s product range because they tend to offer great value for money and contain good ingredients.

We were interested to try Thermopure because it’s well-reviewed and is aimed at both women and men.

What’s in it?

Thermopure contains some classic fat burning ingredients such as Green Tea Extract, Caffeine and Vitamin B6. Each capsule also contains Raspberry Ketones, which several studies have shown to have the potential to boost fat loss by increasing the release of stored fat in the body.

Any negatives?

This is a more affordable product and probably for that reason, the ingredients are not quite as good as those listed above. Sadly it also doesn’t contain Cayenne Pepper, one of the most important fat burning ingredients.


This is a good product to try if you’re on a tight budget. But if you’re looking for top quality, we’d recommend one of the other products above.

5) Bulk Powders Cutting Edge

Product website:

cutting edge fat burner

The fifth and final product on our list is Bulk Powders Cutting Edge.

It’s billed as one of the strongest fat burners on sale today and is branded as a Lipid Metabolising Formula.

What’s in it?

Like most of the products above, Cutting Edge contains Green Coffee Extract and Caffeine to help increase your metabolic rate and keep your energy levels up.

It also contains Black Pepper Extract to help increase absorption and Glucomannan to work suppress your appetite.

Any negatives?

Our main concern about this product is that although it appears to be on sale for both genders, there is no specific mention of women on the website.


We like this product overall and it has some great ingredients, but we’d want some reassurance from the manufacturer to confirm that it is indeed suitable for women.

So there you have it, our pick of the top five fat burners for women on sale right now.

Is there anything else I should know?

We’ve already mentioned this above, but it’s worth repeating. None of the products above will have the full effect of helping you burn fat easily unless you make sure you’re eating healthily and exercising regularly.

We all want that tight and lean beach body but the simple fact is that without the hard work, it’ll be difficult.

However, there’s no better feeling than knowing you’ve put in the hard work and seeing the results for yourself, and choosing the right fat burner can help you get there quickly when combined with the right approach to your diet and exercise.

Also remember that because most of these products contain moderate doses of Caffeine (great for burning fat), it’s best to take them in the first half of the day.

Conclusion – our final thoughts

We’ve taken you through the key things to bear in mind when looking for a good fat burner and have also shown you some of the best products on sale today for women.

There are lots of products out there for women these days, but we’ve picked Leanbean and Instant Knockout out as our favourites right now. That said, you won’t go wrong with any of the products listed above.
