11 Best Fat Burners for Women (Reviewed and Ranked)

Fat Burner supplements are always going to be an “ideal of hope” for millions of people around the World.

And fat Loss is probably the number one goal among people who are looking to make physical changes. So, most wouldn’t think twice to use any advantages (Supplements) to speed up the process.

Products labeled as a fat or weight loss aid attract a lot of interest since 45% of overweight people and 67% of obese people in America are trying to lose weight. And Americans spend $2.1 billion on fat loss supplements annually. (1)

But then you have to include the fitness fanatics who want to get a leaner and more impressive physique…

Now, there are countless products formulated to help people meet their weight goals and many are great. But it’s important to know which ingredients you’re ingesting for your own safety and to experience the desired results.

Nearly all “fat burners” contain herbs and scientifically studied ingredients. But whether or not they work is the question. Caffeine is undoubtedly the most common weight loss aid. But we’ll also discuss other ingredients that may be worth your time.

No single ingredient in a “thermogenic” supplement will directly torch fat stores. But a good product can increase the body’s fat-burning capabilities.

So, we chose the best we could find so that you may see how they work for yourself…

Old School Labs is a proven brand which delivers on quality, their products are third-party tested and there’s not a single artificial substance contained in the product.

They also don’t include any proprietary blends, but rather, they disclose everything that they include in their fat burner. So, it’s our best pick of the bunch.

Leanbean Fat Burner: Why only Female-Focused?

Leanbean sounds interesting and it definitely is. This fat loss supplement contains an array of ingredients included to support women’s goals and health. 

In addition, it’s low-stimulant so no hulk raging in the gym but you’ll get a nice energy boost without the jitters and crash. 

Key ingredients include the water-soluble fiber Glucomannan that can soak up 50x its weight in water. This can help to delay stomach emptying and take up space in the stomach to help prevent overeating.

There are other ingredients that seem to have decent research behind each one for helping with suppressing the appetite and boosting the metabolism.

There are also several key vitamins and minerals to fill in the gaps of what a woman needs to maintain good health. 

Leanbean is our top choice but we also like the others on this list too.

Burn Lab Pro is a scorching hot fat burner product that is formulated to help maintain muscle while you drop the fat lbs.

It contains an all-natural formula that combines 1500mg HMB, 375mg Forslean (forskolin), and 75mg Capsimax cayenne pepper to tap into fat cells, boost metabolic rate, suppress appetite, and possibly increase exercise performance too. 

HMB has shown to preserve and help build muscle while the other ingredients are added to support calorie burning. 

Then you have a dose of Nutrigenesis GTF chromium that helps to optimize insulin which is a key hormone to preventing fat storage and control appetite.

Another thing we like about this fat burner is that the veggie capsules are infused with prebiotics that feed probiotics or healthy gut bacteria. 

Burn Lab Pro is also stim-free and vegan.

It’s also a top choice for MMA athletes looking to shred up, so we think it could be an option worth looking at.

Old School Labs – Vintage Burn Muscle-Preserving Fat Burner

Old School Labs is a popular brand of nutritional supplements because they’ve built a reputation for producing quality products!

Vintage Burn is no exception but it is a unique fat burner in that muscle preservation is a focus. Which is just as important for women as it is for men.

Each serving contains green tea leaf extract (330mg), green coffee bean extract (270mg) which research shows may help to promote weight loss. (9)

Raspberry ketones are added because animal studies show possible benefits for metabolism. (10) 

But in humans, the evidence isn’t sufficient for any beneficial fat-burning properties. However, raspberry ketones may affect adiponectin, a hormone that can decrease appetite and increase your body’s ability to burn fat.

There’s 150mg of caffeine and 100mg of garcinia (Little evidence for weight loss).

Another ingredient that has a little more evidence behind its efficacy is forskolin (60mg per serving). Studies show forskolin to aid in weight loss by increasing fat metabolism and decreasing appetite. (11)

Forskolin can even increase lean body mass along with weight loss, without causing adverse side effects. (12)  

And that’s likely why this product is marketed as having muscle-preserving benefits.

Dr. Emil Nutrition – Bedtime Burn Non-Stimulant PM Fat Burner + Sleep Aid For Men and Women

Fat loss and better sleep?… sound like a dream supplement (Pun intended).

But Dr. Emil’s Bedtime stimulant-free fat burner and sleep aid have some really good ingredients which we think you’ll like.

There’s 300mg of magnesium per serving, which is a very important mineral for nerve and muscle function. Evidence exists that magnesium may improve sleep; however, it shouldn’t be used as a treatment for sleep issues. (13, 14)

Magnesium is used as an ingredient in ZMA (Sleep aid) supplements which also contain B6 and Zinc. And there’s a lot of positive feedback for this combination of ingredients.

Another ingredient is Epigallocatechin gallate from green tea leaf extract which is said to be responsible for the beneficial properties in green tea extract. There’s evidence that shows it to have strong antioxidant properties even shown to have anti-cancer benefits. (15)

L-theanine (250mg per serving) is an amino acid contained in different teas. Electroencephalograph (EEG) studies have shown L-theanine to have a direct effect on some functions of the brain. Many people take it for stress and anxiety and one study showed it to have a significant effect on mental alertness.

But its calming effect can indeed help with sleep due to the anxiolysis effects. (16)

5-HTP is a precursor to the neurotransmitter serotonin, and there is evidence that suggests benefits for weight loss and appetite suppression. (17)

Ashwagandha is an ayurvedic herb commonly used for stress, anxiety, depression, and even for its anti-inflammatory properties. And there is sufficient evidence to support its therapeutic efficacy. (18)

And finally, this fat-burning/sleep aid has 5mg of melatonin which science says it’s potentially beneficial for helping with sleep disorders. (19)

Nobi Nutrition Premium Women’s Fat Burner

Nobi Nutrition’s women’s fat burner contains an effective proprietary blend of calcium beta-hydroxybutyrate, sodium beta-hydroxybutyrate, and magnesium beta butyrate.

These are known as exogenous ketones which are supposed to help you achieve ketosis.

Ketosis occurs when fat becomes the primary source of energy and carbs are kept to an absolute minimum. So ketones actually replace glucose as a main fuel source and protein is utilized to preserve muscle mass. (20)

And although studies are mixed, some research has concluded that exogenous ketones are an effective way to help achieve ketosis.

Havasu Nutrition – Fat Burn Detox For Women

This fat burner also contains ingredients that help with the detox process.

Conjugated Linoleic Acid (CLA) has shown to provide some possible benefits for fat loss in humans but studies are mixed. However, a dose of 3.2 grams per day may cause a modest amount of weight loss. (21)

Apple Cider Vinegar is good for a lot of reasons but whether or not it’s good for detoxification is uncertain. However, there have been studies showing ACV to have an effect on fat loss in rats and mice.

But, one study showed ACV to be potentially beneficial for post-meal glucose levels. Many individuals were given a bagel, orange juice, and peanut butter, and then they were given 20g of ACV after the meal.

The study concluded that ACV significantly lowered post-meal glucose levels. And another study found some weight-loss benefits with ACV, although it doesn’t have large benefits. (22, 23)

White kidney bean extract is an interesting ingredient in this supplement. But according to one study, 25 people were given either white bean extract or a placebo. The white bean extract group lost more weight and reduced weight size. (24) 

Plenty of green tea extract and garcinia Cambogia is also added for potential fat loss benefits.

Jacked Factory – Burn XT Thermogenic Fat Burner

Each serving of Burn XT contains 700mg Acetyl-L-Carnitine HCI, 450mg of green tea leaf extract, 270mg caffeine anhydrous, 50mg of Capsimax (cayenne pepper fruit extract), and 5mg of Bioperine (Black pepper fruit extract).

Acetyl-L-Carnitine HCI is a form of the amino acid L-carnitine which is responsible for energy production from long-chain fatty acids. (25)

As far as the cayenne pepper goes, some evidence suggests it may have a minor effect on burning calories, and speeding up the metabolism. But it’s worth adding to your diet and supposedly its effects are more pronounced with people who don’t consume it often.

Black pepper extract has thermogenic properties and it also helps with the absorption of several nutrients like Curcumin and beta-carotene. (26)

Legion Phoenix Fat Burner

Another intriguing option to add to our list of best women’s fat burners is Legion Phoenix. 

It’s a research-inspired formula that has 200mg caffeine for an energy boost and focus, and KaempMax® Thai Ginseng containing methoxyflavones that may increase energy expenditure, and enhance blood flow which could offer a range of benefits.

An ingredient you may not be familiar with is grains of paradise which is a spice in the ginger family. A study on non-obese females who supplemented with grains of paradise found a significant increase in calories burned compared to placebo. They concluded that it may be a safe and effective weight-loss tool for preventing the accumulation of visceral fat gain (27).

Each serving contains 30 mg of this ingredient which falls into a proven therapeutic range. 

Forskolin and fucoxanthin are also added of which we’ve already explained the benefits. 

Caralluma fimbriata, an edible cactus, was supposedly used many years ago in India to suppress appetite when food was not as readily available (28).

While some research shows little to no benefits, there’s some evidence that shows it could help with obesity by reducing appetite (29, 30, 31). 

But there really needs to be more research to say with confidence that it’s an effective ingredient for supporting fat loss. 

Legion Phoenix fat burner also contains a few other ingredients one of which is L-dopa that produces brain chemicals responsible for cognitive function and metabolic rate. Apparently, overweight and obese individuals have impaired L-dopa production, and using a quality supplement may enhance brain function. 

This product is lab-tested and there are no artificial ingredients.

What Exactly is a Fat Burner?

A fat burner is a product usually in pill or powder form; which claims to aid in the process of fat/weight loss.

These types of products usually contain many ingredients that may or may not be beneficial for weight loss but we’ll provide information on them. Keep in mind though, the listed ingredients will vary between each product and some may not be included.

Common fat burner ingredients include:

• Green Tea extract
• Caffeine
• Capsaicin
• Green coffee bean
• Glucomannan
• Yohimbe
• Raspberry ketones
• Forskolin
• Conjugated linoleic acid
• Pyruvate
• Garcinia Cambogia
• Carnitine
• Fiber

Green tea extract contains plenty of antioxidants and nutrients which is a benefit on its own. But studies show it to have little effect on weight loss itself, even though it’s a very common ingredient in most fat burner supplements. (32)

Caffeine is a nervous system stimulant that increases heart rate and stimulates thermogenesis, which is a process your body uses to generate heat and utilize food for energy. Research shows caffeine to have some effects on weight through calories burned and possibly appetite suppression.

And a safe amount to consume daily is 400-500 milligrams or less. If you consume too much though, you could experience some dangerous side effects. (33)

Capsaicin is a chili pepper extract and studies show it to have many benefits for human health and weight loss in obese individuals. And the majority of studies show there to minimal if any side effects as chili peppers are largely consumed by people Worldwide. (34)

Check out the products below to learn about the additional ingredients on the list…

How Do They Work?

Fat-burning supplements activate certain mechanisms in the body which contribute to fat cell reduction.

Here are the main benefits…

Increased resting metabolic rate (RMR)

The rate at which your body breaks down a fuel source for energy is called the resting metabolic rate. Caffeine is known to have an effect on RMR which burns more calories.  But fat burners are most effective when you’re physically active, and therefore, you’ll burn a maximum amount of calories. (35) 

Increased fat oxidation

Fat oxidation occurs when fatty acids are transported into mitochondria, where they’re then combined with oxygen to provide a fuel source. Green Tea extract may have some fat oxidative effects during rest and exercises according to studies. (36)

But, this finding is also somewhat inconsistent between studies.

Exercise is the best way to achieve this fat oxidation but it’s good to know certain substances may slightly improve the process. (37)

Appetite suppression

Certain ingredients like caffeine can suppress appetite. And the less you eat the more weight you’ll lose. It’s a simple process but you need good nutrition to do this safely and effectively. (38)

Who Should Use a Fat Burner?

If you’re a healthy individual who has a decent tolerance to caffeine products and is not sensitive to herbal supplements.

Fat burners can work effectively to aid you in your weight-loss efforts but you want to make sure you use caution as you would with any other nutritional supplement or foreign substance you introduce into your diet.

Final Remarks

“Fat burners” aren’t a miracle supplement and they will not do the work for you. So, you must eat right and exercise for them to be effective.

They’ll only aid you by improving certain functions in the body which may be beneficial for burning calories and increasing your metabolic rate.

The products we’ve selected are generally safe when used by healthy, and preferably, experienced individuals. So, try one out if you need a little boost toward reaching your weight loss goals.
