How it works:
Quick Overview
This is one of the most popular female fat burners on the market, and we can see why. The creators have put serious consideration into the formula, including ingredients like glucomannan and chromium picolinate to help support common diet struggles.
They also put our needs first by excluding caffeine anhydrous – a potentially dangerous stimulant for women.
In the formula, we get some thermogenic ingredients but it’s not as potent as we’d like. Instead, Leanbean comes out on top for its excellent ability to keep hunger cravings at bay. A key issue for women, cravings can be hugely detrimental to effective fat cutting so, a thermogenic supplement that addresses this factor is a great product in our eyes.

How it works:
Quick Overview:
With just six ingredients on the label, it’s the pure power of this formula that places Hunter Burn so highly on our list of the best thermogenic supplements for women.
The ingredients used are extremely potent and delivered in scientifically-backed servings that should offer some of the most reliable fat burning results when accompanied by a good diet and plenty of exercises.
Our only hesitation with placing this formula in the top spot came about because it’s missing one powerful thermogenic ingredient – Caffeine.
However, the cayenne pepper and matcha green tea servings were very generous, and we know many women prefer supplements without added stimulants. Therefore, it deservedly sits in a top spot.
All of this adds up to make it one of the best thermogenic supplements for women.

How it works:
PhysiqueSeries by Transparent Labs is a complete thermogenic supplement which supports weight loss in multiple ways. That is, through increasing your metabolism, curbing food cravings and increasing fat oxidation.
We like the fact it makes losing weight enjoyable. By including stress-reducing compounds like L-Theanine and L-Tyrosine, women can overcome the psychological battle that regularly accompanies weight loss efforts.
PhysiqueSeries might contains some of the industry’s best metabolism boosting ingredients however it might not be the best for women, hence the fifth-place position. The caffeine content is rather high at 240mg – you also get a natural source of caffeine from the green tea too.
The formulation is 100% transparent though so you’re able to see exactly what you’re taking. In all, it should be a clean and safe way to approach enhanced fat loss.

Now you know which are the very best thermogenic fat burners for women, you should brush up on what a thermogenic actually is.
If you didn’t know already, this is the perfect place to learn more about this type of supplement and find out how it can affect your body.
A thermogenic fat burner is all about heat.
Certain compounds within a thermogenic ingredient work by heating up your body. To produce this extra heat, your body needs to burn additional calories.
By pushing your body into a state of thermogenesis, your metabolic rate is raised, and you should burn more calories than you normally would.
They can be found in a range of foods and are often used to weight management supplements to support weight-loss diets.
Whilst thermogenic supplements will give your body that extra boost it needs to ramp up fat burning, there are other things you can do to take your results to the next level. HeySpotMeGirl have put together our top 3 tips to ensuring you’re getting the most out of your thermogenic – so you can achieve that slimmer figure quicker!
It’s really important to get into the mindset of being healthier – and you can start with your diet. Cutting out processed, sugary or high-fat foods and drinks will make a huge difference to the speed in which you trim down that stubborn fat. Swap all those unnecessary calories for whole foods like leafy greens, lean proteins, fruit and vitamin-packed snacks and watch your curves firm up that much quicker. The good news is, thermogenic fat burners are packed with appetite-suppressing nutrients to make the step to eating ‘clean’ easier – and put a plug in those unhealthy snacks.
Whether you’re a total novice in the gym or have your own workouts you enjoy regularly, making a solid plan weekly will really help you stick to your targets. If you already do cardio, why not take up strength training alongside? Lifting weights has been known to accelerate muscle growth – and burn off fat at the same time. Whatever you decide to do, make sure you’re doing some kind of exercise at least 3-4 times a week to keep calorie burn constant. Plus, with your thermogenic you will have energizing nutrients to help take your workouts to the next level.
Whenever you’re changing your lifestyle, you need to be consistent. Choosing a healthier, more active regime will be hard at first – but getting into a habit will only happen if you keep it up and stay organized. The same can be said for taking your thermogenic fat burner as per the directions advised, to ensure all the nutrients can be absorbed. This will help maximize every single ingredient so you enjoy the benefits of each – and melt those calories quicker!
Natural thermogenic ingredients can be found in a number of foods. However, some are proven to be more potent than others.
Here, we’ve created a list of the very best thermogenic fat burners you can expect in a high-quality supplement.
This is a dehydrated form of caffeine, the stimulant found in hot drinks like coffee and tea.
Caffeine anhydrous is proven to heighten the metabolic rate and increase your overall calorie burn [1].
On top of this, it can help your body to use fat as a fuel for exercise, over carbohydrates [2]. This study found that caffeine increases focused on fat burning by up to 13% [2].
Within cayenne pepper, there is a powerful alkaloid called capsaicin. These cause the sensations of heat and pain you feel when eating a hot chili pepper.
It’s also a powerful thermogenic.
A scientific study has proven its ability to raise the metabolic rate and increase the amount of calories you burn [3]. The same study found the alkaloid helps your body to specifically target fat as fuel.
In a review of 20 different individual studies, the overwhelming finding was that capsaicin consistently raised metabolic rate by an average of 50 calories a day [4].
This ingredient contains two thermogenic fat burning qualities.
It contains small amounts of caffeine which, as we’ve mentioned above, can help to increase metabolic rate and enhance fat burn.
On top of that, it contains catechins called ECGC, which can also boost your metabolic rate through thermogenesis [5].
In fact, one trial found that fat burning increased by up to 17% when drinking green tea before moderate exercise [6].
Here are a few things that are an absolute red flag in the world of thermogenic supplements for women. Avoid these things to find a safer, more effective weight loss aid.
Rule number one when choosing the best thermogenic for women is to avoid any product that uses its own proprietary blend. In this day and age, all manufacturers should be transparent about which ingredients they use and exactly what doses too.
But unfortunately, they don’t have to be this honest.
If you look at the ingredient labels of some fat burner pills, you’ll see the term ‘proprietary blend’. This means the manufacturer that formulated the supplement won’t disclose the total servings for each ingredient.
In other words, you have no idea how much of each fat-burning nutrient you’re getting.
Let’s say for argument’s sake that you needed 500mg of green tea extract to boost fat oxidation. In a proprietary blend, you’ll only see that green tea is in the product – but you won’t know if there’s 500mg or 5mg.
You’re basically going in blind and hoping for the best.
And that’s simply not the best approach for optimal fat burning. It doesn’t guarantee the effectiveness of your supplement and it may not be safe either. For us, it’s a definite no.
Yohimbe is basically the active ingredient in Yohimbine. However, it’s still allowed to be added into supplements – even though Yohimbine has been banned, due to causing harmful side effects.
Is Yohimbe safer? No, it’s not.
For this reason, this is one of the nutrients we try to avoid when we can.
Side Effects:
Also known as Bitter Orange Extract, this has been commonly reported to cause harmful side effects; which is why it’s been banned in the UK & Canada.
Basically, Synephrine became popular after Ephedrine was banned. It’s believed to offer the same benefits and became known as the perfect replacement.
However, since then, Synephrine has gained a bad reputation – after causing numerous side effects when added into supplements.
For this reason, it’s high on our list of fat burning ingredients to avoid.
Side Effects:
If you stick to reasonable servings of caffeine, green tea, and capsaicin, you should be safe [7].
Issues can arise if you take too much caffeine, as the stimulant can lead to unwanted side effects like headaches, migraines [8], nausea and anxiety [9].
The US Department of Agriculture recommends an upper limit of 400mg a day to ensure a safe, side-effect-free experience [10].
Ensure you don’t overshoot this amount by factoring the extra stimulant content from your thermogenic fat burner into your daily amount. From there you can adapt and adjust your coffee and tea intake to accommodate this extra amount.
Here, we’ve given you a lot of information about the best thermogenic fat burners for women.
From the top-performing supplements on the market to the ingredients you should be avoiding, we hope you have enough information to pick the right product to suit you and your weight loss needs.
After a close review of thermogenic supplements, we think out top five of Hourglass Fit, Instant Knockout, Leanbean, Hunter Burn and Transparent Labs PhysiqueSeries will reap the best rewards.
