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, 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.

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

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

It relies heavily on garcinia cambogia to suppress appetite which makes it a good candidate for 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.

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


  • ​One of the few vegan-friendly fat burners for women.

  • ​The caffeine dose 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.

​2. Powher

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 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 products on the market.

Powher Fat Burner


  • ​3g of konjac fiber in each daily dose is scientifically proven to be the optimum for weight loss
  • Vegetarian and vegan-friendly, and gluten-free
  • ​Money-back guarantee if you are not satisfied


  • ​Currently only available on their official website

Powher fat burner and weight loss supplement has been specially designed to help women achieve their weight loss goals safely, and more quickly than they would without taking supplements.

​3. Instant Knockout

The Instant Knockout fat burner by GNC 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 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 to boost metabolism safely and effectively as well as helping build and maintain lean, powerful muscles.

Instant knockout

Sure, there's a bit of caffeine, but the dose here is mild compared to some, and you'll never wind up with the jitters as a result.


  • ​A well-balanced formula of proven fat burners.
  • ​Helps build strong, resilient muscle tissue.
  • ​Enhances energy levels and focus.
  • ​Satisfaction guaranteed or your money back.


  • ​Not suitable for vegans.

This product is a pure formulation that will help reduce food cravings, power up your workouts and help you lose weight, stave off the creation of new, essentially useless fat stores. Make sure to eat healthy foods for best results.

​4. ​PhenQ

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

The net result is a product that lives up to the considerable hype surrounding it 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 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.



  • Helps burn excess fat through thermogenesis.
  • ​Enhances energy levels and focus.
  • ​Moderate appetite suppressing capabilities.


  • ​Shouldn’t be taken too close to bedtime.

Capsimax powder to promote thermogenesis, calcium carbonate to reduce the likelihood of storing excessive amounts of fat and caffeine to increase metabolism and get you up and ready to roll at the gym.

​5. LEAN-XT Non Stimulant Fat Burner

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

Its ingredients include metabolic boosters 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 isn't the same as a double espresso, there is caffeine nonetheless.

LEAN-XT Non Stimulant Fat Burner

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.
  • ​Helps to suppress appetite.
  • ​Money back satisfaction guarantee.


  • Despite claims, contains some caffeine.

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

​6. Transparent Labs

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

It 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.

It's 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.

Transparent Labs

If that's not a problem for you, then you're going to love Transparent Labs.


  • ​Caffeine and L-theanine for energy.
  • Green tea extract to facilitate muscle recovery.
  • ​Forslean and cayenne pepper to burn through stubborn fat deposits.


  • ​Heavy on the caffeine.

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

​7. RSP QuadraLean

QuadraLean 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. 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. 

RSP QuadraLean


  • ​Enhances your natural metabolic processes.
  • ​Suppresses appetite to help you keep weight off.
  • ​Can be stacked with a range of other health supplements.
  • ​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

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.

It will also help you build the kind of lean, strong, and healthy body you have in mind.

Leanmode 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 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. 

​Evlution Nutrition Leanmode


  • Increases metabolic rate for fat loss.
  • ​Provides energy to power fat-burning workouts.
  • ​Helps muscles recover faster and grow stronger.
  • ​Improves oxygen flow to both muscles and brain.


  • Don’t expect a caffeine boost from the coffee content.

Together, these and other ingredients 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 a Good Fat Burner

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

As such, the​se should include some or all of these 5 ingredients:

  • 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 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.
  • 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 coffee extract helps you maintain your energy levels and burn more fat.

  • 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 suppress your appetite. 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 your metabolic rate have thermogenic qualities and will help you burn fat even while at rest. Caffeine and green tea are two such ingredients.

​​​​What to Avoid in Fat Burners for Women?

what to avoid in fat burners
  • ​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 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. 


​Are There Any Potential Side Effects?

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.
moody woman
  • 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 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.
