About The Product

Vampire fat burner is made by Insane Labz and is designed to boost your metabolism and promote fat loss. It costs $69.99 for 30 serving containers, with a serving size of 2 capsules per day.

The serving size isnt great, as studies have shown 3-4 capsules spread throughout the day delivers the best results.

We dont have great first impressions either; every ingredient inside Vampire fat burner is part of a big proprietary blend (well expand on this later on).

Anyway, well analyze Vampire fat burners nutrient profile. But first, well tell you more about the company behind it.

Who are Insane Labz?

Insane Labz have built a good reputation for themselves in 2017, especially through their pre-workouts products.

In all honesty, we didnt learn much about their company from their website; their about us section didnt contain any useful information, such as the year they were founded.

However, this doesnt affect the quality of Vampire fat burner. So lets take a look which ingredients Insane Labz added inside this supplement.

Vampire Fat Burner Ingredients Explained

There are 8 ingredients inside Vampire fat burner, which is a good number to have in a supplement; we notice that products containing over 10 nutrients are usually under-dosed.

However, one bad thing is that every ingredient is part of a proprietary blend (well explain this in more detail below)…


Proprietary blends are mixtures of numerous ingredients thatre only shown to you as 1 quantity. As you can see from the Vampire Blend on Vampire fat burners ingredient list, the overall amount is 1,100mg - but youre not shown the dosages of each ingredient inside such as Caffeine.

This increases your risk of side effects, and also makes it uncertain whether this pre-workout will work. For this reason, we try to avoid any supplement that contains proprietary blends.

Not only that, we can see that Vampire fat burner contains 2 ingredients known for causing side effects; Citrus Aurantium and Rauwolfia Vomitoria Extract.

Anyway, well explain everything in more detail below, as we take you through each ingredient. By the end of this review, youll know exactly how safe and effective Vampire fat burner is.


Heres Everything You Need To Know:


L-Carnitine is a great addition to a pre-workout supplement; its able to reduce muscular fatigue and damage, while improving your focus in the gym.

However, its important to know that its only shown to work in dosages of 500mg per serving.

As L-Carnitine is inside a proprietary blend, you dont know the exact amount inside Vampire fat burner - meaning its might be under-dosed.

Not only that its also important to remember that this is a fat burner, so its not really needed here. For this reason, we dont believe L-Carnitine will be very effective in Vampire fat burner.

Caffeine Anhydrous 

In case youre wondering, Anhydrous means that Caffeine has been dehydrated into powder form, so it can added into supplements.

Its usually the best stimulant you can find in supplements, but not when its added into a proprietary blend; as its a stimulant, it can cause jittery side effects when consumed in unknown quantities.

For this reason, we have to warn you that theres a risk of jitters and energy crashes with Vampire fat burner. We advise that you only consume supplements providing the exact dosage of Caffeine inside - to stay safe.


Also known as Conjugated Linoleic Acid, its believed to promote fat loss. But the bad news is that studies havent proven that it actually works.

That doesnt mean its completely useless though; its known to help preserve muscle mass while you cut fat.

For this reason, it can be a good bonus nutrient, but its definitely not a key nutrient in Vampire fat burner.

Juniper Berries 

In case youre wondering, this is the same stuff you add to your gin & tonic.

It contains antioxidants, which can improve your general health. However, no study has proven whether Juniper Berries can promote fat loss - meaning its an unnecessary ingredient in Vampire fat burner.


Green Tea Extract 

Green Tea Extract is a perfect addition to any fat burner, as its proven to boost your metabolism and promote fat loss.

In fact, everyone knows how beneficial it is; whether you drink it as tea, or consume it in supplements, itll improve the health of almost every organ in your body.

However, its much easier consuming it through supplements, as youll need to drink a lot of green tea to consume the necessary amounts of catechins to benefit you.

The real problem here is that Green Tea Extract is part of a proprietary blend, so you cant say for sure whether youre consuming the optimal amount of this nutrient.

As a result, we cant confirm whether itll be effective in Vampire fat burner.

Garcinia Cambogia Extract 

Garcinia Cambogia is a fruit that gained attention for being able to promote fat loss. However, its not actually shown to work in any studies, so we consider it to be an ineffective nutrient here.

Citrus Aurantium 

Also known as Bitter Orange Extract, this has been commonly reported to cause numerous side effects. Although we will acknowledge that its shown to boost your metabolism.

But as it can be potentially harmful, we always advise you to avoid supplements containing Citrus Aurantium.

Rauwolfia Vomitoria Extract 

Rauwolfia Vomitoria Extract sounds pretty intimidating, and this should be a warning sign; its shown to cause numerous side effects in studies.

For this reason, its one of the ingredients that we advise you to avoid when choosing a supplement.

Its important to know that there are safe and effective nutrients available, so theres no need to consume ingredients that can put your health at risk.

Side Effects

Its worrying that theres 3 ingredients in Vampire fat burner that can cause side effects; Citrus Aurantium, Rauwolfia Vomitoria Extract and Caffeine Anhydrous.

In case you skimmed past the section above, well give you a quick summary below.

Simply put, Citrus Aurantium and Rauwolfia Vomitoria Extract have both shown to cause numerous side effects (which well bullet point later), and Caffeine Anhydrous can cause jittery side effects when consumed in unknown quantities.

Ultimately, we always advise you to know the exact dosages of each ingredient you consume - and avoid products containing proprietary blends when possible.

Heres the potential side effects from taking Vampire fat burner: 

  • Anxiety (Citrus Aurantium & Rauwolfia)
  • Nausea (Citrus Aurantium & Rauwolfia)
  • High Blood Pressure (Citrus Aurantium & Rauwolfia)
  • Jitters (Caffeine in unknown dosages)
  • Energy Crashes (Caffeine in unknown dosages)

Vampire Fat Burner Review Conclusion

Insane Labz have built a reputation for themselves as creating the strongest supplements on the market. However, this means that they take risks and add potentially harmful ingredients into their products - putting you at harm.

We feel that theyve taken a step too far with Vampire fat burner; it contains 3 nutrients that can cause side effects, in a proprietary blend, which increases your risk of suffering from them.

For this reason, we cant recommend this fat burner to you. We advise you to look elsewhere to spend your money more wisely.

Bottom Line

Vampire fat burner contains some great nutrients, but its a shame that everything has been added into a proprietary blend.
