While everyone would love it if there were a magic weight loss pill or product that was also safe, the fact is we haven't developed one yet.

But, just because the perfect fat burner supplement hasn't yet been invented, that doesn't mean that there aren't some pretty darn good ones on the market right now.

Today's fat burners are built on decades of available information like research and real-world experience, and are some of the most sought-after supplements on earth.

That's because the best of them really do work for weight loss, even if they're not quite magic.

That said, each of the products below have staked credible claims to be some of the best fat burners for women.

Top Fat Burners for Women (2020)

1 - LeanBean (Editor's Choice)

Leanbean bottle

LeanBean was designed for women to help provide them with a safe and effective method for weight loss, fat burning and preventing the formation of new fat deposits.

LeanBean is one of the few vegetarian and all natural fat burners, as well as one of the best fat burning supplements for non-veggies too.

It relies heavily on garcinia cambogia as an appetite suppressant, which makes it a good candidate for a stimulant free supplement.

There's a modest dose of caffeine to give your workouts a boost but nothing that's going to disrupt your sleep cycle. If a flatter stomach, firmer butt, and greater stamina are notions that interest you, this is an ideal fat burner for you.

The B complex of vitamins B6 and B12 plays and important role in healthy body weight, in particular vitamins B6 and B12 have been the fundamental in helping you achieve a normal, energy-yielding metabolism. It also has raspberry ketones for quicker fat breakdown.

LeanBean can help you to achieve those weight loss goals safely and quickly without sacrificing your overall nutrition.

  • One of the few vegan-friendly natural fat burners for women.
  • For a fat burner, it does an above average job suppressing appetite
  • The caffeine dose from green tea extract is moderate
  • Your money back if you are not completely satisfied
  • May cause an upset stomach

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. We talk more about this fat burner in our LeanBean review and why it's considered as the best fat burner by many females.

2 - PhenQ


PhenQ contains an amalgam of fat burning and thermogenic ingredients, appetite suppressants, and energy boosters.

The net result is a fat burner supplement that lives up to the considerable hype surrounding weight loss and does so safely and without cleaning out your bank account.

The makers of PhenQ have gone to great effort to create one of the best weight loss pills that gets the job done without creating jitters, upset stomachs or insomnia.

About the only downside of PhenQ as a fat burner is that the appetite suppressant aspect of it is not everything it’s hyped up to be and a little lacking when compared to others on this list. But beyond that, it's all good.

3 - Instant Knockout

Instant Knockout Box

The Instant Knockout fat burner by Roar Ambition has earned major props for being the best fat burning and weight loss supplements out there.

Rather than getting all its metabolic enhancing energy from caffeine alone, Instant Knockout fat burner looks to nature in the form of green tea extract, green coffee extract, cayenne pepper, zinc, vitamins B6, B12 and more.

All of these are known as weight loss and natural fat burning supplement ingredients that work to boost metabolism safely and effectively, as well as build and maintain lean, powerful muscles, leading you to your weight loss goal.

Sure, there's a low does of caffeine from coffee and green tea extract, but the dose here is mild compared to some, and you'll never wind up with the jitters or any of the nasty side effects as a result.

4 - Powher Fat Burner

Powher Fat Burner For Women

Powher, a female fat burner and weight loss supplement, is made by Ultimate Life, a company that produces and market supplements in energy, weight loss, fat loss, and sleep.

Powher cut is a weight loss and fat burning supplement that works to speed up your body and helps you lose weight aims through its use of Konjac Fiber, Caffeine and a number of other vitamins and minerals.

The focus on the scientific integrity of the ingredients - and doses - suggests real attention to detail that is missing from a lot of similar fat burner products on the market that promise to help you lose weight.

  • The Powher fat burner has 3g of konjac fiber in each daily dose which is scientifically proven to be the optimum for weight loss
  • Vegetarian and vegan-friendly, and gluten-free fat burner for women
  • Currently only available on their official website

5 - LEAN-XT Stimulant-Free Fat Burner

LEAN-XT Non Stimulant

Lean-XT fat burner attacks the problem of stubborn fat deposits from all angles.

Its ingredients include metabolic boosters and fat burning components to prevent new fat stores from forming, appetite suppressants to keep you away from the refrigerator and coleus forskohlii for enhanced cardiovascular health.

If we have a bone to pick with Lean-XT, it's that the makers advertise it as stimulant-free, when in fact, it counts green tea extract among its ingredients.

And while the caffeine load from green tea extract isn't the same as a double espresso, there is caffeine nonetheless (be on the look out for side effects especially if you're sensitive).

Lean XT fat burner requires you to take three capsules on an empty stomach twice daily. For best results, take 30-60 minutes before meals with the first serving before breakfast and second serving before exercise. Do not exceed 6 capsules in a 24-hour period.

So take that for what it's worth.

  • Includes coleus forskohlii for cardio health
  • Enhances metabolic function to help you lose weight
  • This fat burner for women helps to suppress appetite
  • Despite claims, contains some caffeine in the form of green tea extract

Beyond that minor quibble, however, Lean-XT fat burner for women is one of the top fat burners and does a commendable job burning off those excess fat stores, while the green tea extract and caffeine load is not enough to keep you awake at night.

6 - Transparent Labs Thermogenic Fat Burner

transparent labs physique series

The Physique Series Fat Burner from Transparent Labs features an impressive list of clinically proven ingredients.

This fat burner provides a multitude of benefits including enhanced metabolic rate, increased energy to power through your workouts and improved mental acuity resulting from more oxygen-carrying blood pumping through your veins.

This fat burner for women is one of the more unheralded items on our list, but you'd do well to give it a shot.

If there is a downside to the Physique Series women's fat burner supplement, it's that they're a little heavy-handed with the caffeine from green tea.

If green tea or caffeine is not a problem for you, then you're going to love the fat burning effects of Transparent Labs.

  • Caffeine and L-theanine to burn fat and provide more energy
  • Green tea extract to facilitate muscle recovery
  • Forslean and cayenne pepper to burn through stubborn fat deposits
  • This fat burner is quite heavy on the caffeine

If it is, you might want to try a smaller dose to avoid the side effects rather than opting out, as this is one of the best diet pills that may help you lose weight and you wouldn't want to miss out because the product as a whole is so effective with a balanced nutrition.

7 - RSP Nutrition QuadraLean Fat Burner

RSP QuadraLean Stimulant 150x150

QuadraLean fat burner is one of the new generation of diet pills that are trying to steer away from excessive dependence on stimulants. The good news is they succeed!

That’s mostly because they focus instead on enhancing thermogenesis which, as we saw above, is the process of elevating your metabolic rate, thus results to fat burning. As a fat burner, this has two primary effects.

First, it helps you burn off the foods you eat before it turns into new fat stores and second, it attacks the fat stores you do have and puts them in play as a source of energy.

Take three capsules on an empty stomach twice daily. For best results, take 30-60 minutes before meals with the first serving before breakfast and second serving before exercise.

  • Enhances your natural metabolic processes
  • This fat burner also works as an appetite suppressant to help you keep weight off
  • No stimulants to keep you awake at night
  • Appetite control claims may be exaggerated

Do not exceed 6 capsules in a 24-hour period. The end result is no more jitters, no more insomnia and no more upset stomachs from ingesting too much caffeine. The icing on the cake is that it’s made in a certified GMP facility so you can be sure of the quality.

8 - Evlution Nutrition Leanmode

​Evlution Nutrition Leanmode

Leanmode's list of ingredients includes scientifically proven metabolism enhancers, fat burners, and energy boosters that will enable you to get more from your exercises, such as garcinia cambogia and L carnitine.

This fat burner claims to help you build the kind of lean, strong, and healthy body you have in mind.

Leanmode fat burner contains L-carnitine, which is one of the building blocks of protein, which of course is the foundation of muscles.

It also includes green coffee bean extract. Green coffee bean works to boost energy and mediate blood glucose levels and CLA, which helps metabolize fat into energy.

As a dietary supplement, take 3 capsules 1 to 2 times daily.

  • Increases metabolic rate for fat loss
  • Provides energy to power fat-burning workouts
  • Improves oxygen flow to both muscles and brain
  • Don’t expect a caffeine boost from the coffee content

The ingredients like green coffee bean and garcinia cambogia allow you to burn fat more effectively during workouts while improving blood flow, oxygen distribution to enhance your focus and recover from strenuous workouts faster than ever.

What to Look for in the Best Fat Burner

Any supplement claiming to be the best fat burner for women should improve your overall nutrition, ramp up your metabolism, help you burn fat and prevent your body from turning carbs into a useless spare tire. An effective fat burner may also work for appetite suppression.

Check out Lumen, if you want to track your metabolism.

As such, these should include the essential fat burner ingredients like:

ingredients of fat burners
  • Caffeine. Still the best natural stimulant ever discovered. If used wisely, caffeine will enable you to perform more vigorous and productive workouts. Even if you don’t work out, caffeine will still get you up and out of your chair, which is the first step in burning calories and reducing body fat. [1] If you are over-sensitive to caffeine, you can try stimulant free fat burners.
  • Zinc. Zinc is known to play an important role in muscle recovery and maintenance. It also helps increase your metabolism, energy levels and stamina. Though not in an obvious way like caffeine. The best fat burner for women should not only burn fat but also prevent muscle wasting as you lose weight.
  • Green Coffee Bean Extract - People often feel like napping after they eat because their blood sugar levels are spiking. Green coffee bean extract can help reduce the absorption of blood glucose. The green coffee bean extract helps you maintain your energy levels and burn more fat. Some of the fat burners for women also rely on green tea extract for this purpose.
  • L-Theanine - L-theanine is an essential amino acid that fulfills a variety of roles including fat burning and helping to restore muscles quickly in the wake of a strenuous workout. Numerous studies have shown that the combination of l-theanine and caffeine burns fat.
  • Cayenne Pepper - Cayenne pepper is one of those ingredients in fat burners that works not by doing something but by preventing you from doing something. In this case, cayenne pepper will help you with appetite suppression. And the less you eat, the less fat there will be to burn. [2]
  • Thermogenic ingredients - Thermogenesis is the production of heat within the body and is driven by your metabolic rate. Any ingredients that help increase metabolism have thermogenic qualities and will help you burn fat even while at rest. Ingredients like caffeine and green tea are two such things that results to effective fat burning.
  • Chromium picolinate - Not a lot of fat burners contain this ingredient, but together with raspberry ketones, it has been shown to bring about effective fat metabolism.

What to Avoid in Fat Burners for Women?

We made sure that the best fat burners for women recommended in this list don't have any of these ingredients.

  • Ephedra - In an unprecedented move, the US FDA banned the sale of products containing ephedra in 2003. Some 150+ deaths related to ephedra-containing products had been reported before the FDA was forced to act. Some companies, however, try to get around the ban by selling over the Internet. The best fat burner and weight loss supplements won’t use it. [3]
  • DMAE - Dimethylaminoethanol or DMAE is included in some fat burners for under the guise that it burns fat and increases cognitive function. It doesn’t. Not only that, but it has a bunch of nasty side effects including headaches, manic episodes, constipation, bloating and insomnia.
  • DMAA - Allegedly the equivalent to a super-espresso DMAA (or dimethylamylamine) is dangerous. There have been reports of cardiac arrest, cerebral hemorrhage, high blood pressure and even death in people who used it. The best thermogenic boosters won’t touch it. [4]
  • Bitter Orange Extract aka Synephrine - While Synephrine is usually safe when consumed in small doses anything more than 50 grams per day could lead to fainting, chest pains, and elevated heart rate. Synephrine might also cause you to test positive for amphetamines on a company drug test. [5

Bitter orange contains an active ingredient called synephrine that is similar to ephedra. In 2004, the FDA banned ephedra for serious side effects on the heart. Many weight loss and bodybuilding products contain bitter orange and caffeine, which can cause high blood pressure and increased heart rate in healthy adults. There is concern that using bitter orange might cause heart problems.

What Are The Side Effects Of Fat Burners?

While fat burners for women are typically safe when used as directed, they have been known to generate some side effects including:

  • Allergic reactions - Some fat burners contain ingredients that may trigger allergic reactions.
  • Mood changes - Fat burners that include stimulants can sometimes generate shifts in a woman’s mood. You may also feel hyperactive or suffer hot flashes or insomnia.
  • Stomach problems - Some with more sensitive digestive systems may find that some fat burners give them an upset stomach. A few might experience diarrhea or constipation.
  • Flatulence - While rare there are still some whose systems will react negatively to some of the ingredients in fat burners. With flatulence being the result.
  • Undeclared ingredients - Some fat burners from unscrupulous manufacturers take advantage of the lack of FDA oversight of the industry to sneak in unwanted ingredients. The most notable is excessive amounts or dose of caffeine. Always buy from a reputable company.
  • Heart palpitations - Because of the sometimes substantial caffeine load found in some fat burners those with a family history of heart problems may want to avoid them. Or at least find one that is free of stimulants.

[However,] overuse of metabolism stimulants has its own adverse effects. Prolonged use causes your metabolism to slow down in self preservation. Thus, these fat burners do not retain their effectiveness for a long time.

How long can women stay on fat burners?

Women can stay on fat burners for about 8 weeks at a time before they should consider taking a break. The main reason for taking the breaks is that your body can become used to the active ingredients resulting in a less effective product.

Timing these cycles with your training routine will be critical to achieving the best results.

Is there a difference between fat burners for men and fat burners for women?

Yes, there is a difference between fat burners for men and women, which mainly comes down to the dosage being delivered. The chosen ingredients are usually the same, but as women can be more sensitive to stimulants, they are often provided in a lower dose.

About the author

  • Thanks to this instant knockout review, I’m now leaner and stronger! Gotta say that this fat burner is legit!

  • I have shed over 30 pounds using this product and with the right gym sessions and regime, I was able to gain so me muscles too. This one is legit. I highly recommend it. I experienced a little bit of a reaction during the first few days, I could not sleep! But eventually my body adjusted to it and I felt great. It gave me more energy and I felt the burn everytime I do my routine. My friend who’s into fitness even commended me because I work too hard and give it my all when I am in the gym! All because of this product. I love that it does it what it’s supposed to do and more

  • Hey Isaac. It has been a while since I last visited your post. By the way, thanks for your awesome breakdown of this wonderful product. I have been using it for a little while now since I saw it in your website. What I have noticed while using this product is that with the high caffeine dosage, I can’t drink a cup of coffee in the morning and take this at the same time without stomach issues. I received an advice from my friend a couple of days ago saying he can help me out with my stomach issues. I look forward to reading more from you. Thanks in advance!

  • Just wanted to say that thank you as always for your in-depth analysis of this amazing product. Since postage, I have been using this product for about 2 months now. Within that span of time, I went from 250 to 210 pounds! It was a great milestone for me because usually it takes me longer to lose so much. To give a background of what I have been doing, I rarely worked out or went to the gym. I just ate healthier, all the fruits and vegetables and less of those junk. I walked 4 miles every other day, and just was sensible about everything I did or ate. I believe it works great for losing stubborn belly fat as my friends have noticed a great loss in my abdomen area and in other smaller noticeable areas of my body. Which is kind of great since it has been a long time that I wanted to get rid of those. Furthermore, most notably though and focused in the stomach. I used to have a very big belly and it protruded out significantly. I don’t really drink heavily though that’s why it makes me wonder why I had it. However, I do notice while on it during my weight loss journey that it did sometimes cause minor weight gain by at most 2 pounds. But really, if you’re at least casually active, you should be able to work that off easily enough. I would recommend if you are a bigger person who may not be as big as I am or was would notice any significant reduction. It will probably take more time if you are already a leaner or fit individual according to my friends who are way, way lighter than me. At my current weight of 210 pounds, it has been harder and extremely slow to lose any more of my weight but I am trying hard to continue to lose the weight and slim down. After all, it has worked for me and I have proven it myself. So let’s keep ourselves posted guys. Once again, thanks Isaac!

  • I’m a 26 year old woman and I’ve been using this magical product for about 6 months now. I found this product online but was a little sketchy until Isaac wrote down his thoughts on it. This pushed me to purchase it doubt-free. When I started using it, I was at around 63kg. Now as of writing this, I am bouncing around 53kg. I couldn’t be more happier than this that I can maintain almost near my ideal weight. To top it off, I lost that much with minimal exercise and limited diet. I guess any pills will work best especially coupled with a healthy diet. I live on a tiny island nation with little to no access to healthy food so for me, maintaining to eat a healthy diet really needed a significant input of an effort which has been worthwhile so far. I started seeing definite changes to my form in the second month. Initially I did suffer from sleeping problems due to caffeine sensitivity. Normally, I don’t drink coffee even when I have to keep myself awake during midnight. However, 6 months later, it’s not so much of an issue now. My biggest sticking point is 4 times a day can be hard to remember sometimes. This is definitely not a joke. As far as I can remember, I probably have wasted my first month because I’d forget to take it later in the day… But overall, I’m happy with the results. I have more energy during the day, and losing those unwanted curves has motivated me to keep on doing strenuous physical activities.

  • Isaac has been my go-to when it comes to this topic. I started taking this pills not so long ago. I was going to the gym maybe 6 times a week before, but I was doing that before I started taking these pills. Definitely, I saw an impact when I ate sweet stuff. I had no idea why. To begin with, I did not even like the taste of it. Because of that, I totally stopped eating it. Also, for some reason, I always felt full. I noticed that my body fat percentage went from 23% to 19% over a 2 month period. Occasionally, I stop using this product because of limited stocks. Since then, I stopped taking them and noticed that my appetite has gone up a bit. But I do feel more controlled when it comes to eating sweet stuff. Would definitely take these again as a quick fix for a holiday body as they give energy during exercise and stop my uncontrollable cravings! Thanks Isaac.

  • I ordered this product a little hesitantly, after trying various products previously which all promised fantastic results immediately but rarely work, and instead saw myself gaining weight which I really hated. I found the price was not overly excessive, especially for a month’s supply. I was definitely sold on your thoughts Sir Robertson as you have always been honest with what you say. Initially not expecting much, I started on day one with my morning pill just before breakfast. Within ten minutes I felt full without taking a bite. This was rather strange. Naturally, I was a little surprised as I did not expect the appetite suppression to take effect so quickly. I continued throughout the course, sticking strictly to my diet and consuming the four pills daily. I have since started the same plan again to really pin down the difference on and off this wonderful product. All in all I would highly recommend this product to anyone struggling to stick to a plan. As much as discipline is important, a well-engineered product makes a world of a difference. I am glad I listened to this author.

  • I decided to try this product after trying several other products that failed my expectations. And after tons of research, I took the leap after I came upon this website. I am a new reader of Isaac but I have never read anything like this before. So I bought it immediately. Boy am I glad I did! I will admit the first couple of days I was on such a high, it was hard to sleep. I eventually got used to it and continued with my weight training. I eat pretty well so I really didn’t change my diet. I had increased energy, stopped eating out of boredom and felt so much stronger at the gym. I was on fire! Even after the first 2 weeks on this product, I saw results. I was in awe! If you are contemplating on trying it out I highly recommend it. Thank you Isaac for bringing out this product. You have really assisted me in reaching my goals.
