Fat burning supplements that actually work can provide the edge you need to get you to your weight loss or cutting goals.

With the right combination of healthy diet and exercise routine, these types of supplements can significantly improve your chances of success.

And because the products I recommend are entirely natural fat burners, you won’t have to be concerned about the snake oil chemicals that are commonly found in less than organic supplements.

Studying vegan fat burners is a bit tricky, so we interviewed several vegan coaches and nutritionists to help us come up with this list.

So, let’s dive right into the list of the top vegan fat burners.

Our Top Vegan Fat Burners (2021 Updated)

1 - PhenQ (Editor's Choice)


Believe me when I say we've tested literally hundreds of commercial fat burners and this brand consistently stands out.

PhenQ Fat Burner is a thermogenic, fat burning powder that has been used by many of my clients as part of a diet and nutrition booster for weight loss goals.

It's safe for both men and women who are serious about losing weight and improving physical performance. My clients rave about the insane energy boost during workouts after taking PhenQ!

But you do need to be careful and possibly take a lower dose if you’re sensitive to stimulants because it contains a significant amount of caffeine.

  • Boosts energy for better gym performance
  • Suppresses appetite
  • Improves overall mood and brain function
  • Replenishes body's lost electrolytes
  • Quite a high dose of caffeine

But those natural stimulants work well to increase your metabolism which can release more energy that comes in handy when you exercise. And with some very good bulk discounts, you can actually save a load of money as well.

2 - LeanBean


This vegan fat burner makes the top part of my weight supplements list for women both for body fat reduction and energy boosting purposes.

I’ve spoken with a few women who take this on a daily basis, and they have achieved some good results.

The green tea extract, along with green coffee bean extract, can have a pretty decent thermogenic effect on your body.

Add to that the turmeric and raspberry ketones, and you can also achieve some naturally higher brain energy.

  • Non-GMO and made with natural ingredients
  • Effective vegan fat burning supplement
  • Appetite suppressant
  • A higher dose of ketones could work better

It contains a good choice of nutrients that women can take on a daily basis to work towards the body they desire. The only downside is that it could do with a bit more ketones.

With 3000mg of Glucomannan, it’s approved for weight loss in the European Union. It’s recommended to take 6 capsules per day: 2 during breakfast, lunch, and dinner, respectively.

3 - Burn Lab Pro

Burn Lab is clearly doing something right.

In my time as a personal trainer, I have watched this brand grow, with their products becoming more and more commonplace at the gym and in recommendations from colleagues and clients.

It’s quite easy to see why they are doing so well, and I have to commend their transparency and dedication to results-driven products.

The Burn Lab Pro fat burner is no exception and it’s one of the best vegan fat burners today because of its top quality ingredients.

  • Claims to help boost energy and burn fat
  • Suppresses appetite
  • No caffeine and vegan-friendly
  • Only available direct through their website

Whilst other fat burners will recommend you take doses 3 - 4 times a day, you should only take Burn Lab Pro once a day, about an hour before working out.

It is specially formulated to be used in conjunction with intermittent fasting, so most users have reported some positive results.

You can use it without fasting and still lose weight, but by leaning in to its intended purpose, you’ll get much better value from the product.

This vegan fat burner is only available direct from their own website, they do offer a 30-day money-back guarantee and there are discounts available for buying in bulk.

4 - Phen375

Phen375 fat burner is formulated in an FDA-certified facility, thus reassuring its users that Good Manufacturing Practices (GMP) are observed in making the product.

After hearing out the testimonies of its users and researching its ingredients, I understood exactly why this product has earned this spot in this article among the many fat burners we tested.

Regular users have reported that they have healthily experienced fat burning and weight loss as the product has caused them to have regular bowel movements, better sleep, and increased energy levels.

Phen375 is not just a dietary pill; it could be your ally in your daily activities. By taking the pill as indicated, you get to enjoy the benefits that come with its healthy and highly refined ingredients.

See the difference between Phen375 and Phentermine.

  • Helps stimulate metabolism
  • Helps reduce food cravings
  • Boosts athletic performance
  • Can only be purchased online

Once you do regular exercise and eat healthily while taking Phen375 fat burning supplement, you may be well on your way to your weight loss journey.

5 - Powher Fat Burner

Powher Cut Product

Powher Cut, Powher’s best vegan fat burner, is specially created for ladies to help you step up your game in your weight loss efforts. It is made with 100% natural ingredients that help you resist food cravings, support healthy blood glucose concentrations, and reduce fatigue.

Its main ingredient is Konjac root or Glucomannan, a type of soluble fiber that also acts as a prebiotic, thus keeping your gut clean and healthy. Furthermore, this fiber is expected to help relieve constipation.


  • Promotes better metabolism
  • Boosts endurance capacity
  • Supports healthy weight loss
  • Some may experience jitters due to its caffeine content

Due to natural caffeine content in Powher fat burner, you may experience caffeine crash. But so far, this is very rare because the caffeine content is minimal.

For better results, follow the recommended dosage of Powher Cut – 2 capsules, three times a day, right before breakfast, lunch, and dinner. Also, remember to exercise regularly and rehydrate more often when taking a fat burning supplement.


6 - Lean PM

Next on my list of vegan fat burners is quite a novel idea and one that I was very skeptical of. Could you seriously lose weight while you sleep?

The answer is yes. Fat loss is possible while sleeping, but not a huge amount. This fat burner is not a replacement for all the other work you put into your diet and exercise, but you can burn an extra 100 to 150 calories with these types of fat burners and similar supplements.

Lean PM fat burner doesn’t just help reduce a little bit of body fat, but it also promotes better and more rested sleep at night as it doesn't contain any caffeine and other stimulants.

  • Speeds up metabolism to burn more fat
  • Green tea extract detoxifies the body
  • Improves sleep
  • Stimulant-free
  • A bit more effective hunger suppression would be good

As a natural fat burner with green tea extract, it may also help detoxify your body in a completely natural way. The only downside I found is that people said it could be better at appetite suppression.

7 - NutraLeaf


My dietitian friend Sam introduced me to NutraLeaf fat burner, and of all the fat burners I’ve tested, it’s the one that I got most curious about.

Countless online reviews highlight that it doesn’t just work for fat loss and weight loss, but it also can help prevent new flabby stuff from forming. Who doesn't want that?

The raspberry ketones help to break down body fat into fatty acids by giving your metabolism just enough of a nudge to be more effective.

  • Made with 100% natural plant-based products
  • Prevents the creation of new fat cells
  • Breaks down stored body fat
  • Appetite suppressant
  • Not entirely based on organic ingredients

Personally, I like taking it on days when I go for longer fasting periods as I do think that the cayenne helps reduce hunger and food cravings.

The only downside I found is that it’s not an organic or all-natural fat burner, but it's still a great option for all vegans who are aiming for fat loss. 

8 - Vintage Burn

Vintage Burn

Old School Labs (OSL) reassures you that Vintage Burn is one of their best vegan fat burners sold in the market.

Here’s why…

Vintage Burn fat burner is manufactured in an FDA-certified facility using only premium ingredients that include raspberry ketones, Garcinia Cambogia, and green tea extract.

Old School Labs claims that these natural ingredients allow you to effectively burn three times as many calories as fat per pound. Quicker fat burning means better weight and fat loss.

Also, one thing to take note of is what sets it apart from the other fat burners. Old School Labs takes pride in uniquely formulating its thermogenic fat burning supplement, making it the only muscle-preserving fat burner.

  • Carefully selected ingredients that help burn fats
  • Supports the preservation of muscle
  • Enhances focus and mood naturally
  • Several users report stomach discomfort after taking it

While Vintage Burn fat burner claims to be one of the best fat burners, you should still check the label before adding it to the cart. Its caffeine content is believed to be relatively higher compared to its competition.

Even so, it is guaranteed 100% vegan-friendly, gluten-free, and works for both men and women. With its special thermogenic quality that burns fat faster than most, Vintage Burn fat burner is one to look out for.


Do Thermogenics Work For Weight Loss?

Yes, thermogenic fat burners work for fat loss and weight loss because of the physiological processes they trigger. (1)

Thermogenic fat burners basically increase your core body temperature slightly, which is achieved by burning more calories. This energy either comes from your nutritional intake or your fat reserves.

Ingredients like green tea extract and green coffee bean extract contain caffeine, which is one of the most effective fat burner and thermogenics available on the market.

Try taking them during fasting periods, and you may notice some good results.

In addition, most fat burners act as an appetite suppressant due to a significant amount of dietary fiber that can help with the feeling of satisfaction for a longer time. It leads to lower food intake, fewer calories, and therefore, higher chance of success with weight loss.

Do Vegan Fat Burners Have Side Effects?

Yes, vegan fat burners can have side effects, but they are most common when these weight loss supplements are taken in excess.

Here are a few things to look out for, as they can also indicate that your body won’t react as well, and you won’t lose weight as fast as you think.

1. Jitters

This is most commonly due to too much caffeine, where you will feel like you cannot sit still or focus your full attention on a specific task. (2) Make sure you’re careful with any product that contains anhydrous caffeine or green tea extract. They are common in supplements that focus on fat burning.

2. Insomnia

If you take a fat burner which has extracts from green tea or coffee bean, then it’s best to try and limit your coffee intake. Doubling up on your caffeine will result in less of a weight loss response, and you can end up struggling with sleep as one of its side effects.

3. Nausea

Excessive intake or allergy to some of the extracts may cause nausea. Just make sure you use a process of elimination, as one of my clients once complained about nausea, which was actually due to a different protein supplement. If you're stacking on supplements, it might be difficult to pin point which specific one produces these kinds of side effects.

4. Headaches

This is also mainly due to excessive consumption of some of the extracts, including caffeine. It’s unpleasant but it will quickly stop and reverse if you reduce the dose or take a break for a few days.

Natural Fat Burning Ingredients

Nutritionists have long recommended certain foods to help with fat loss and fat burning, and this isn’t just down to limiting your calories. All of the above products take advantage of some proven and natural health benefits from at least some of the sources below.

1. Caffeine: It’s All About Stimulants - This is one of the most effective thermogenic ingredients. But before you decide to stand in line at Starbucks several times a day, just note that after a certain daily amount, you’ll actually become used to it, and the weight loss effect and its function in fat loss won’t be as efficient.

From a metabolic standpoint, combining caffeine with exercise is like putting premium fuel in a European sports car. It simply runs better than it does with regular unleaded in the tank.

2. Green Tea Extract: More Than An Antioxidant - I personally don’t like the taste of green tea so much, but I’ve been taking the extract in various supplements on a regular basis to help my body burn fat. Beyond helping to detoxify, green tea can work well with caffeine to help with fat burning that can result to a more effective weight loss. (3)

3. Soluble Fiber: To Fill You Up - When you want to lose some extra pounds and avoid weight gain, then it’s all down to limiting your food intake. Small meals and snacks are better, as well as some fasting. What soluble fiber does is fill you up more with stuff that doesn’t increase your calories.

4. Yohimbine: The African Secret - It’s believed to have originated as an aphrodisiac, so be careful about what this might do to your love life. 😉 But beyond some additional bedroom activity, it’s also been shown to help directly with weight loss through effective fat burning. (4)

5. Raspberry Ketones: Get Some Brain Energy - Staying focused on work and exercise tasks is vital to helping you maintain motivation. Raspberry ketones are a good way to increase brain energy to reduce distractions.

6. Coleus Forskohlii: An Ancient Medicine - While there isn’t any scientific consensus on its direct impact on fat, it is believed to improve testosterone levels, which may help you perform more intense workouts, and may aid in muscle recovery as well.

7. Capsaicinoids: Chilli Without The Burn - Don’t worry; you won’t have to burn your mouth to burn some belly fat. This difficult to pronounce substance can be taken as an extract, and studies have shown that it will help to reduce body fat.

8. Synephrine: A Difficult One To Find - This one is difficult to source, and in many cases, it’s also going to cost you quite a lot. However, my dietician said I should mention it because there are a few weight loss and fat burning supplements out there that contain this natural fat burning ingredient that may help you in fat burning and losing weight.

Concentrated Fat Burning Ingredients


The following fat burning ingredients are quite difficult to get enough of in the food you eat. Some of them are available in protein powders because they help with muscle recovery, but I personally like seeing them on the labels of fat burners as well.

1. Conjugated Linoleic Acid (CLA)

This is a modified version of Omega-6 and not something your body can produce, so you have to get it through your diet. It has been shown to work quite well for getting rid of stubborn fat stores resulting to quicker fat loss.

2. L-Tyrosine

This is one of the 20 standard amino acids and is believed to help with fat burning and fat oxidation, as well as appetite suppression. More and more companies are choosing to add this, and you’ll pretty much always find them in cutting stacks. (5)

3. L-Carnitine

This wonder of nature has recently been proven to be directly linked to transporting fatty acids that were metabolized from fat to your muscle fibers. As a result, you reduce the risk of a bottleneck when trying to melt away some love handles.

Many people look to L-carnitine as a way to help shed unwanted pounds and lose weight fast. When combined with diet and exercise, some studies have found that supplementing with it can, in fact, be an effective way to enhance weight loss.

Common Non-Vegan Ingredients In Fat Burners To Look Out For

Not all plant-based products will actually say they are vegan on the label. So, what you’ll need to do is look at the ingredients list and see if you can find any of the following. If you do, then avoid them at all costs:

  • Gelatin
  • Glutamic Acid
  • Progesterone
  • Glucosamine
  • Linoleic Acid

There are a lot of other things that are generally common in fat burning and weight loss supplements, but these are the ones I found on some thermogenic fat burners.


1. What is the best vegan fat burner and appetite suppressant?

The best vegan fat burner and appetite suppressant is L-tyrosine and Garcinia Cambogia. Combined, they work quite well to curb food cravings and melt away that flabby stuff to get beach ready.

2. When should you take vegan fat burners?

You should take vegan fat burners just before you eat a meal or snack. I generally recommend it this way to speed up absorption and limit any chance of nausea. However, when and how to use fat burners also depend on the dosage and ingredients of the specific vegan fat burner. The product should have a recommendation on when to take them.

3. Are vegan fat burners safe?

Yes, vegan fat burners are safe, as long as you stick with the recommended dose and avoid any products that you could be allergic to. Always check the label, and if you’re uncertain, try starting with a lower dose.

4. Should vegans take fat burners?

Yes, vegans should take fat burners if they have some big weight loss goals. Even a small increase in the speed of melting stored fat will add up over a few weeks and months.

Can you use a vegan fat burner with other supplements?

Yes, you can use a vegan fat burner with other supplements. However, there's always a risk that certain ingredients in a supplement may not work well in conjunction with other ingredients.

It's best to always check the instructions on the labels in case there are warnings and certain contraindications.

Also, it's not a good idea to take two different non-vegan or vegan fat burners as it may cause overdose on some ingredients. Caffeine, for example, is a common thermogenic and stimulant added to a fat burning supplement which can cause serious side effects when consumed in excess.

How do you use fat burners?

Fat burners are used as a short-term tool to manage your weight. Therefore, it must be supplemented with a healthy diet and exercise routine for you to get the best results. These fat burners simply enhance your weight loss through certain fat burning ingredients.

Constant supplementation of fat burning supplements or any other type of supplement may cause your body to adapt to certain ingredients which can lower the efficacy of their fat burning effects.

Therefore, it's a good idea to take cycles of around 4 weeks on and 2 weeks off to prevent serious side effects. Check the labels for instructions as it can vary from one product to another.
