  • Not the safest choice
  • It is not for everyone

Iron Brothers Thermoburn Review at a Glance:

Iron Brothers Thermoburn can help you lose some weight. However, is it the best choice to aid your weight loss journey? Unfortunately no.

It is full of stimulants. And since stimulants can cause numerous side effects, it is not the best option. Especially if you suffer from obesity-related diseases. 

That said, we wouldn’t recommend it to everybody.

Its formula is indeed strong, but at what cost. If you are not a hardcore fitness enthusiast, this product may not be for you. In our opinion, there are safer weight loss products on the market.

About Iron Brothers Thermoburn

Iron Brothers Thermoburn is a fat burner in the form of dietary capsules. It is suitable for both men and women and claims to:

  • Boost your energy levels & enhance physical performance
  • Boost metabolism, burn fat and help you get faster results
  • Improve mood & focus

There is also a similar supplement by Iron Brothers with an almost identical name. Its name is Thermoburn Stim-Free Fat Burner. As you can guess from its name, the main difference is that it has no stimulants.

So even though their names may be similar, their formulas are not. That said, it’s important to distinguish between these two.

In this review, we focused on “standard” Iron Brothers Thermoburn, not the stimulant-free version.

Iron Brothers Thermoburn Ingredient Analysis

Iron Brothers Thermoburn Ingredients

For whatever reason, there are multiple formulations under the same name of Iron Brothers Thermoburn. For example, the formula on Amazon is different than the one on the official Iron Brothers website.

In this review, we focused on the formula from the official website. We don’t know if Iron Brothers will change it in the future, but at the time of writing this review (December 2021), it consists of the following:

  • Caffeine Anhydrous 275mg
  • Citrus Aurantium extract 75mg
  • Grains of Paradise Extract 60mg
  • Cayenne Pepper Powder 50mg
  • Theobromine 50mg
  • L-Theanine 50mg
  • Yohimbine HCL 3mg
  • Toothed Clubmoss Aerial Parts Extract 2.5mg
  • Bioperine 2.5mg

Caffeine

Caffeine is a stimulant and the key active compound in coffee.

Caffeine is shown to give us a plethora of benefits. The main ones are enhancement of physical performance and mental stimulation. Caffeine makes you more alert and improves your overall strength and endurance.

The standard caffeine dose for weight loss supplements is around 200mg. This means that 275mg in Thermoburn is a good dose.

However, there is the catch. Habitual use of caffeine can lead to tolerance, which dulls its effect. This means that this dose will not have the same effect on everyone.

Citrus Aurantium

Citrus Aurantium is another name for Bitter orange. It is a fruit-bearing tree that grows in Asia. And just like caffeine, it is a stimulant.

Its main active ingredient is synephrine, which is very similar to the banned substance ephedra. And since ephedra’s ban, many weight loss and bodybuilding supplements started using Citrus Aurantium instead.

However, even though is often used for weight loss and improving athletic performance, there is no solid scientific evidence that supports its benefits over potential side effects.

Grains of Paradise

Grains of Paradise is a spice closely related to Ginger. For now, studies show some preliminary evidence for fat-mass control. This is why more and more weight loss supplements are starting to use it.

However, all these claims need to be confirmed by more research. Although promising, there isn’t enough human evidence to fully support its benefit.

Cayenne Pepper

This is a great ingredient. The studies show that it is effective for not only burning fat, but suppressing appetite as well. And that’s exactly what you want from a quality weight loss supplement. 

Cayenne Pepper has anti-inflammatory properties, which makes it a great all-rounder.

However, the dose in Thermoburn seems too small. 50mg of cayenne pepper is noticeably underdosed compared to the dosages used in the clinical trials. Most studies have used dosages up to 20x larger than that.

L-Theanine 

L-Theanine often comes alongside caffeine because of its synergistic effect. While caffeine is a stimulant, L-Theanine promotes relaxation.

This means that L-Theanine has an antagonistic effect on caffeine and helps neutralize its side effects – high blood pressure, jitters, restlessness, and others.

When in combination, theanine & caffeine most commonly come in a dose of 200mg each. 

This means that compared to 275mg of caffeine in Iron Brothers Thermoburn, 50mg of L-theanine seems noticeably underdosed. Especially considering that Thermoburn is packed with many other stimulants as well.

Yohimbine

We are not too happy about seeing Yohimbine on the list! Although it is effective for fat-burning, it also may cause adverse side effects.

It increases adrenaline levels in the body, and as such, may cause anxiety. Yohimbine can also adversely interact with other ingredients in Iron Brothers Thermoburn – more so stimulants.

On its own, the Yohimbine dose doesn’t seem problematic. But, the fact that it comes alongside so many different stimulants may be.

Bioperine

Iron Brothers Thermoburn contains Bioperine as well. Bioperine is a patented black pepper extract, which improves absorption rates. This means that due to Bioperine, the ingredients will hit your system faster.

Our Commentary on Iron Brothers Thermoburn’s Formula

Thermoburn by Iron Brothers is PACKED with stimulants. This guarantees strong formula. But, more doesn’t always mean better. 

Because of a formula that is stuffed with stimulants, it is not for everybody. To some people, it may be even problematic and cause adverse side effects. So in that context, we don’t think it is the best option.

Thermoburn does work though. The ingredient list is decent. 

If you are a pro bodybuilder who needs to cut weight fast before the competition, this product may be for you. 

But for everyone else, we think there are better and safer options on the market.

Side Effects

Iron Brothers Thermoburn is full of stimulants. That said, some side effects are possible. The most common are :

  • Heart palpitations
  • Stomach pain
  • Heartburn
  • Jitters
  • Shivering
  • Headaches
  • Nausea/vomiting

Also, Thermoburn contains Bioperine. This means it may not be for long-term use because Bioperine can greatly increase intestinal permeability.

Manufacturers also state that Iron Burn Thermoburn is not for people under the age of 18 nor women who are pregnant or breastfeeding.

Testimonials & Reviews

Since for whatever reason Iron Brothers Thermoburn comes in different formulations under the same name, it’s not that easy to find a third-party customer review for a specific version.

But generally speaking, the reviews are mixed. Some people claim Thermoburn shows great results, others say it’s ineffective, while the rest complains it caused them side effects.

Honestly, this doesn’t surprise us because it’s obvious that Thermoburn is not designed for a broad audience. Due to stimulant-rich formula, it’s mostly intended for hardcore fitness enthusiasts. It’s clear Iron Brothers Thermoburn is not for everyone and it would be ridiculous to expect everyone will like it.

How to Use Iron Brothers Thermoburn

On the official site, instructions on how to take these supplements are pretty vague. The only info you get is that the serving size is 1 capsule. When and how to take them is not stated.

But from our experience, it’s best to take Thermoburn first thing in the morning, on an empty stomach.

Pricing, Availability, and Other Things to Consider

On the official Iron Brothers website, Thermoburn sells for $29.97. Each bottle contains 60 capsules.

According to recommended serving size (1 capsule), this should serve you for 2 months.

Takeaway

Iron Brothers Thermoburn is not for everybody. It does work and can help you lose weight. However, it is far from the best product. 

Its formula is full of stimulants, which is never the safest option. 

If you are not a hardcore fitness fanatic, we wouldn’t necessarily recommend it. There are healthier and stimulant-free weight loss supplements out there that can achieve the same or effects without the risk. But if you don’t mind the aggressive formula, Iron Brothers Thermoburn might be exactly what you need to take your body to another level.
