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 isn’t great, as studies have shown 3-4 capsules spread throughout the day delivers the best results.

We don’t have great first impressions either; every ingredient inside Vampire fat burner is part of a big proprietary blend (we’ll expand on this later on).

Anyway, we’ll analyze Vampire fat burner’s nutrient profile. But first, we’ll 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 didn’t learn much about their company from their website; their ‘about us’ section didn’t contain any useful information, such as the year they were founded.

However, this doesn’t affect the quality of Vampire fat burner. So let’s 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 (we’ll explain this in more detail below)…


Proprietary blends are mixtures of numerous ingredients that’re only shown to you as 1 quantity. As you can see from the ‘Vampire Blend’ on Vampire fat burner’s ingredient list, the overall amount is 1,100mg – but you’re 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, we’ll explain everything in more detail below, as we take you through each ingredient. By the end of this review, you’ll know exactly how safe and effective Vampire fat burner is.


Here’s Everything You Need To Know:


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

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

As L-Carnitine is inside a proprietary blend, you don’t know the exact amount inside Vampire fat burner – meaning it’s might be under-dosed.

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

Caffeine Anhydrous 

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

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

For this reason, we have to warn you that there’s 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, it’s believed to promote fat loss. But the bad news is that studies haven’t proven that it actually works.

That doesn’t mean it’s completely useless though; it’s known to help preserve muscle mass while you cut fat.

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

Juniper Berries 

In case you’re 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 it’s an unnecessary ingredient in Vampire fat burner.


Green Tea Extract 

Green Tea Extract is a perfect addition to any fat burner, as it’s 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, it’ll improve the health of almost every organ in your body.

However, it’s much easier consuming it through supplements, as you’ll 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 can’t say for sure whether you’re consuming the optimal amount of this nutrient.

As a result, we can’t confirm whether it’ll 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, it’s 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 it’s 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; it’s shown to cause numerous side effects in studies.

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

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

Side Effects

It’s worrying that there’s 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, we’ll give you a quick summary below.

Simply put, Citrus Aurantium and Rauwolfia Vomitoria Extract have both shown to cause numerous side effects (which we’ll 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.

Here’s 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 they’ve 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 can’t recommend this fat burner to you. We advise you to look elsewhere to spend your money more wisely.
