  • Ingredients: Calcium, calcium HMB, citicoline, yohimbine
  • Dosage: 4 veggie capsules
  • Cost per serving: Approximately $1.10
  • Servings per container: 45


Legion Forge is one of our favorite fat burners, and it especially lends itself to pre-workout use. It doesn’t work quite like other fat burners do: It makes no claim to turbocharge your energy level or to kickstart your metabolism. What it does do is help you preserve muscle mass during your workouts, while actively eliminating some of that “stubborn fat” that compromises your figure. It also provides improved mental focus, allowing you to really zero in on your fitness goals during each and every workout. A transparent ingredient list and robust money-back guarantee make this a product that’s easy to recommend.

  • Cost per serving: Approximately $2.30
  • Servings per container: 30


PhenQ fat burner approaches belly fat weight loss holistically. The brand claims to promote weight loss in five ways: helping you burn fat for energy, preventing food cravings, boosting energy, balancing mood, and hindering fat accumulation. PhenQ sets itself apart with its clean list of natural ingredients that appeal to many women. Its key ingredient is a-Lacy's Reset, a proprietary blend that includes science-backed compounds to help target fat for energy production and oxidation, promoting weight loss. The good news is there aren't any artificial sweeteners, though the amount of caffeine per serving is something to consider. Taking two pills twice daily is recommended, giving you 300mg of caffeine, the equivalent of drinking three cups of coffee. If the product isn't a good fit for you, the company makes it easy to return with its 60-day money-back guarantee.

How We Chose the Best Fat Burners for Women

There are a good number of fat burners for women out there, and not all of them are created equal. To curate the products featured in this article, we meticulously considered a range of crucial factors.

  • Dosage. We made sure to choose supplements that came with dosages that are actually effective at helping women burn through unwanted flab and fat.
  • Simplicity. Generally speaking, we have a preference for ingredient lists that are short, clear, and focused on natural/clean substances.
  • Price point. Fat burners can be expensive, especially when you use them with each daily workout. We tried to focus on fat burners for women that offer real value.

What is a Fat Burner?

A fat burner is a nutrition supplement available on the market that claims to promote weight loss in myriad ways.(4) Some fat burners may promise to increase fat breakdown, weight loss, calorie burn, or fat oxidation during exercise, while others say they help prevent fat absorption or help your body adapt to changes that promote fat breakdown. Fat burners come in liquid, capsule, powder, tablets, gummies, and more. Recent research discusses a lack of knowledge of the safety and efficacy of fat burner supplements, so use them with caution to avoid compromising your health.(5)

How Do Fat Burners for Women Work

Different fat burners work in different ways, but some of the most common mechanisms include:

  • Boosting your energy level, with caffeine or natural vitamin dosages, allowing you to get more out of each workout without succumbing to fatigue.
  • Triggering thermogenesis, a bodily process that actually helps you burn fat from the inside out.
  • Increasing your metabolism, allowing you to convert food into energy and even to burn through some of the fat stored in your body.
  • Promoting digestive health, allowing you to more effectively use nutrients rather than storing them as excess flab or tissue.

How to Choose the Best Fat Burner for Women


Supplements can be expensive, and you want to ensure your purchase aligns with your budget. Our rating scale is $-$$$. $ = under $1 per serving, $$ = $1-2 per serving, and $$$ = over $2 per serving.

Serving Size, Dosage, and Form

The nutrition content of a particular supplement is crucial; however, if it takes three to four doses to deliver that nutrition in one serving size, it may be hard to reap the product's benefits. It can be cumbersome to swallow up to two capsules at a time or remember to take your dosage twice a day. Supplement form also matters. If swallowing is difficult, you may choose a powder supplement over a capsule. You might feel like mixing a powder into your food isn't ideal for your on-the-go life, so you may just want to swallow a pill and move along with your day.


If burning fat is your goal, your body needs a calorie deficit or negative balance. High-calorie supplements can potentially sabotage your weight loss efforts depending on what else you eat or how active you are throughout your day.


Much of the supplement industry produces products without added sugar; however, some continue to use artificial sugars. According to recent research, it helps to be aware of what makes a product sweet because artificial sweeteners, though generally recognized as safe, may increase cancer risk. Consider choosing natural products sweetened with fruit extracts such as monk fruit or Stevia extract.


Most fat burners contain some stimulant to increase your metabolic rate, promoting weight loss. Caffeine is the most common stimulant, so be sure to read the label to see how much is in the product and consider how much caffeine you already consume in your everyday life.

Fat Burner Ingredients

Many brands choose fat-burning ingredients that work synergistically to accelerate fat loss.(4) Here are some common components and their functions.

  • Caffeine may show thermogenic benefits, promote fat breakdown, and increase nervous system activity.
  • L-carnitine may lower fat mass, increase muscle, and promote fat oxidation.
  • Green tea extract may increase fat oxidation with its catechin constituents.
  • Conjugated linoleic acid is an omega-6 fatty acid compound that may reduce energy intake, lower fat production, increase calorie burn, and fat breakdown.
  • Forskolin is a plant ingredient that may promote fat breakdown and lower body weight.
  • Fucoxanthin is a carotenoid in brown seaweed that may suppress fat accumulation and reduce fat tissue.

Our Final Takeaway

Sometimes, even rigorous exercise and a consistent diet are insufficient for burning through unwanted fat. By offsetting your healthy lifestyle with natural supplements, you may be able to achieve the fat-burning effects you desire. We hope our recommendations provide a good starting point.

FAQs About Fat Burners for Women

Do fat burners work?

With hundreds of fat burner supplements available online, it's not easy to know if any of their claims are trustworthy. The FDA monitors supplements but doesn't test or evaluate dietary supplement claims. The truth is, there's no guarantee the ingredients in fat burners will be effective, though many of them are using ingredients that may help promote weight loss as long as you're also eating well and exercising.

Which fat burner is most effective?

The most effective fat burner isn't easy to say because not every burner is guaranteed to be effective. Our pick for the overall best fat burner for women is PhenQ because of its clean, science-backed ingredients and potent formula that hits weight loss from five angles. PhenQ is highly reputable, and popular, and may be effective for many, according to reviews. Lastly, besides a particular fat-burning brand, generally, fat-burners are most effective when added to a healthy eating and exercise regimen.

Do fat burners work without exercise?

A 2016 study showed that the ingredients in fat burners effectively increase resting metabolic rate (RMR), which is your body's ability to burn calories at rest, and can lead to weight loss over time if you eat a healthy diet.(6) Though it's crucial to maintain a caloric deficit diet alongside an active lifestyle to reduce your body weight, you may still be able to lose weight by taking fat burners without exercise and diet.

What is the best time to take fat burners?

Since most fat burners contain stimulating ingredients such as caffeine, it would be best to take them when you need the most energy. Many people are looking for an energy lift in the morning or early afternoon, which would be the best time to take a fat burner supplement.

Who should not take fat burners?

Always talk with your medical provider before starting a new supplement. You shouldn't take fat burners if you have liver problems, high blood pressure, a BMI less than 18.5, or are under 18.(7)
