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 are 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.

It’s true that most supplements are designed for men, but our list will show you the best fat burner supplements for women on the market right now, based on the ingredients formulas and customer reviews.

But do fat burners really work? The truth is that fat burner supplements have something of a bad reputation these days.

There are definitely some low quality products out there that you’ll want to stay away from. But once you know what to look for, finding the best high-quality safe and natural supplement to assist you on your journey will be easy.

Luckily for you, we’ve broken down some of the key ingredients you should look for when searching for the best fat burner and how they help you to get lean and shed those stubborn areas of fat.

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
• Glucomannan
• Green Coffee Extract
• Cayenne Pepper
• Black Pepper Extract

Most of the products we’ve picked below contain a good amount of Caffeine (apart from the top rated product Leanbean), 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.

The 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.

Leanbean fat burner results

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 favorite supplements, this is definitely one of the more premium-priced products around, but that’s the (literal) price we have to pay for the best ingredients.

• It’s 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.

2) 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.

3) PhysiqueSeries Fat Burner

Product website:

PhysiqueSeries Fat Burner

PhysiqueSeries Fat Burner is made by Transparent Labs and has a decent formula to help you shed the pounds.

Transparent Labs make a big deal about the fact that they “transparently” reveal the ingredients of their products, meaning that you know the exact doses.

This is great news, we’d never recommend any products that use proprietary blends, and none of the supplements on this list do.

What’s in it?

PhysiqueSeries ticks some of the important boxes when it comes to what you should be looking for in a quality fat burner supplement.

It contains a good dose of Green Tea Extract and Cayenne Pepper, two of the best ingredients you should be looking for.

It also combines Caffeine with the amino acid L-Theanine, which can bring about an energy boost without the jitters.

The main thing missing from this supplement is a separate ingredient to suppress appetite. Attacking fat from multiple angles is crucial, and an appetite suppressant such as Glucomannan (used by both of the products at the top of this list) can make sticking to your diet much easier.

That’s why it we only rate it as the third best product on this list.

Any negatives?

• No specific appetite suppressing ingredient (such as Glucomannan).

• 5-HTP not an effective fat burning ingredient.

• Synephrine HCl known to cause issues when combined with Caffeine.


PhysiqueSeries is definitely a decent option if you’re looking to burn more fat. It contains some solid ingredients but is missing some important things such as an appetite suppressant, which is why we’ve only given it three stars.

4) Lean 11

Product website:

WMN Lean 11

Lean 11 is the new fat burner supplement offered by WMN, which is a female-only brand recently launched by Bulk Powders.

Lean 11 claims to use a “premium formula” to help women burn more fat quickly, using 11 different ingredients.

Like Leanbean, it’s been specifically formulated for women and the official website says that it can contribute to slimming.

What’s in it?

Lean 11 uses some of the best fat burning ingredients around at the moment, including Green Tea Extract, Chromium and Green Coffee Extract.

It also uses some other somewhat more unusual ingredients, such as Apple Cider Vinegar, Kola Nut Extract and Choline.

Instead of Caffeine, Lean 11 uses a branded stimulant ingredient called Coffeine®.

It also uses Bitter Orange (Citrus Aurantium) as one of its main ingredients. We are not huge fans of this ingredient because it’s been known to cause problems when combined with stimulants such as Caffeine.

It was a shame that Lean 11 doesn’t use Glucomannan as an appetite suppressant or Cayenne Pepper as a metabolism booster.

Any negatives?

• Citrus Aurantium and Caffeine together may be unsafe.

• No Cayenne Pepper or Glucomannan.

• Some unproven fat burning ingredients.


Lean 11 has a decent formula and the good news is that it’s been formulated specifically as a fat burner for women. The not-so-good news is that it doesn’t contain Cayenne Pepper or Glucomannan, and that Citrus Aurantium combined with Caffeine could cause side effects.

5) 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.

Unlike Lean 11, it’s marketed towards both men and women and is one of Bulk Powders’ premium products.

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.

Sadly it doesn’t uses Cayenne Pepper, one of the best fat burning ingredients, and the formula also omits Green Tea Extract.

Any negatives?

• No Cayenne Pepper or Green Tea Extract.

• Uses some unproven fat burner ingredients.


Cutting Edge is a decent option but we don’t consider it as one of the very best fat burners on the market because it doesn’t use two of the most important ingredients – Cayenne Pepper and Green Tea Extract.

We like this product overall and it has some great ingredients, but we’d also 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 Leanbean is clearly the market leader in terms of ingredients and effectiveness. That said, you won’t go wrong with any of the products listed above.
