Fat Burners for women – an overview and a disclaimer

A “fat burner” is a dietary supplement made up of natural food and plant extracts, along with vitamins and minerals. These formulas are meant to help support your goals of weight loss.

This type of supplement has come under fire across the health and fitness industry, as they’re often marketed as some kind of shortcut, or magic pill to weight loss – especially when targeted towards women. Some ingredients commonly found in natural fat burners for women are backed by clinical support, but not all and not all ingredients are served at effective levels. Therefore, it’s important to closely analyse a product before you buy. 

Fat burners for women should always be approached as a support to a healthy lifestyle, to help you achieve a calorie deficit. They will not work alone, and you shouldn’t rely on them to do so

To achieve weight loss, you need to be enjoying a healthy, calorie-restricted diet and doing plenty of exercise. A high quality fat burner for women may complement this and offer support along the way. You may try it and find it helps you stick to your goals, or it might not do a lot for you. 

To help you find the best fat burners for women that show the most potential, we’ve carefully reviewed and ranked some of the market-leading supplements in this category. 

As we review the best fat burners for women, we’ll be using a strict criteria, discussing the quality and quantity of ingredients involved, the research surrounding them and the likeliness they’ll impact your weight loss effort. On top of that, we’ll be putting safety and pricing under the microscope to make sure you find the best all-round women’s fat burner.

Ranking – How do we rank the best fat burners for women? 

The world of supplements is a confusing and complicated place. Without regulations in place, anyone can make a supplement without really even looking into any research and call it ‘the best fat burner for women’. 

Luckily, we’re pretty familiar with all the most popular ingredients for this type of supplement, and the most recent research published about them.

We’ve looked into the ingredients, the science, customer reviews and answered all the most common fat burner FAQs to bring you a complete guide to finding the best fat burner for women. 

Here’s what we had in mind throughout the review: 

Is it effective?

Are the ingredients within this supplement well-known and highly researched? And if they are used, do the serving sizes match up to the research and other similar supplements? 

Once we answered those questions, we took a look at customer reviews. The ingredients may add up on paper, but the best way to assess effectiveness is to find out how it performed in real life situations. 

Is it safe?

When it comes to safety, we know fat burners don’t have the best reputation. So we took extra precautions when it came to assessing safety.

In particular, we kept an eye out for ingredients that have been well-tested and are deemed to be generally safe to use.

We also kept an eye on the stimulant level too. While caffeine is one of the most highly-researched thermogenic ingredients in the industry, it’s also abused by some manufacturers who serve it at extremely high levels. 

This is particularly dangerous for women, as research shows we can be more sensitive to the negative side effects of caffeine than men [1]

To keep our readers safe, and to avoid any nasty side effects, we have chosen not to include any product that contains more than 300mg of caffeine for a daily serving. 

Is it intelligent?

As we mentioned a moment ago, a lot of supplement manufacturers overfill their capsules with caffeine, because it’s backed by research. However, if you really look into the science, studies show that too much could actually be detrimental and dangerous [2] [3]

This is just one example of how lazy fat burner design can be damaging to your health and a huge waste of money.

Instead we looked for supplements that provide a safe experience, and that should help you lose weight through a number of different avenues.

For example, we were on the lookout for raised metabolism, appetite suppressants, portion control and energy boosters. All of these should work together to offer a range of supports. 

What’s the company and product reputation like?

There’s a reason so many of us trust well-known brands – because they inspire trust and they’ve created a good reputation through good practices. 

By looking at the reviews of previous customers, and the other supplements offered by the manufacturers of these products, we managed to get a good idea of whether these were quality fat burners. 

To help guide this, we looked at good manufacturing processes, the facilities the products were made in and whether a supplement is available worldwide. 

The best fat burners for women – FAQ’s

There’s a lot of confusing information out there about what a fat burner is, and what it can realistically achieve for your body. Here we answer all the most frequently asked questions about fat burners, to help you get a good understanding of what they are and how they work. 

What are fat burners for women?

A fat burner is a dietary supplement, often made up of natural ingredients that have been linked to weight loss in some way. They usually contain food extracts, plant extracts and vitamins and minerals with the intention of supporting weight loss. 

They are not a magic pill that will make you lose weight and should not be relied upon to do so. 

The key to weight loss is achieving a calorie deficit through an energy restricted diet and exercise. A women’s fat burner may help to support this process, but it is extremely unlikely it alone will lead to weight loss. 

Do fat burner pills work?

As we mentioned above, a fat burner is not powerful enough or strong enough to influence weight loss alone. There is also no scientific research to prove that they will work.

As the industry is also unregulated, there’s absolutely no guarantee that any formula will ‘work’.

Some supplements may offer a higher quality formula through research backed ingredients, optimal serving sizes and good manufacturing processes, but there is still no guarantee it will work.

The best fat burners for women can only support your weight loss efforts and offer you an additional crutch, which may help you to stick to your weight loss plan for longer, or more easily. 

How long do fat burners take to work?

Weight loss happens when you stick to achieving a healthy calorie deficit over a prolonged period of time. Therefore, this is the key to seeing the results you’re looking for, a fat burner may help you get there faster, but expect to put weeks of dedication into this. 

In terms of a fat burner, they will start to take effect on your body as soon as they’re digested. Usually, this is around 30 minutes after you’ve swallowed them.

Are fat burners for women?

A fat burner supplement can be used by any adult, man or woman. They contain natural ingredients that should be received well by your body. However, high stimulant fat burners can be dangerous, and are more likely to leave women with uncomfortable side effects. 

As such, we’d suggest women choose a fat burner with a maximum of 300mg distributed throughout the day. Or, if you’re particularly sensitive, go for an option with no added stimulants. 

Are fat burners for women safe?

The safety of a fat burner depends on the formula. Overall we’d suggest avoiding the following things in a fat burner supplement:

  • Caffeine levels higher than 300mg
  • Proprietary blends – unknown blends of undisclosed ingredients (potentially dangerous)
  • Synthetic ingredients – lab made ingredients aren’t tolerated well and could lead to side effects
  • Yohimbe, bitter orange extract, synephrine – all ingredients have been linked to health issues and should be avoided

ALWAYS consult your doctor or physician before taking a fat burner supplement. Especially if you’re already taking medication.

NEVER take a fat burner supplement or anything containing caffeine if you’re pregnant or breastfeeding. 

Are there side effects to a fat burner?

The potential side effects of a weight loss supplement for women depend on the formula. If it’s high in caffeine, you could expect heart palpitations, headaches and migraines. 

It could also interrupt sleep if taken too close to bed. 

Always read the ingredients label and research the ingredients involved before you purchase it to ensure you’re fully aware of potential side effects. 

Speak to your doctor if you’re concerned about side effects. 

Final word

In our review of the best fat burners for women, we found that, when paired with a restricted calorie diet and plenty of exercise, each of these products should have what it takes to help support you with your goals.

They all provide different benefits and therefore may help to promote weight loss in a number of different ways.

Each supplement is of a high quality, is well researched and should be safe to use.

We picked out Leanbean as our top choice for best fat burners for women, but you may find one of the others suits you better. Either way, we’re happy to recommend them all as a good support.
