Thermo Burn Review

Thermo Burn is a thermogenic fat burner made in the USA for Iron Brothers LLC. The company founder and CEO is a man named Marc Burton, who claims to be just a regular guy who loves supplements and working out.

The Iron Brothers website fails to state how a regular guy learns how to formulate supplements. It seems likely Iron Brothers supplements may be made to order by a manufacturer who specializes in producing products companies can brand as their own.

Iron Brothers Thermo Burn

The Iron Brothers product catalog is diverse. In addition to sports supplements, Iron Brothers also has nootropic supplements, sleep aids, and an oral supplement that provides liver support. The company has its own range of gym wear and training accessories as well.

Like a lot of fat burners that are aimed at the gym-going crowd, Iron Brothers Thermo Burn is high in stimulants. The present formulation provides 275 mg of caffeine per dose. That’s more caffeine than you’d get from a treble espresso. It’s a lot and the Thermo Burn formulation contains additional stimulants as well.

I refer to it as the present formulation because Iron Brothers has changed it a number of times. Ingredients come and ingredients go but the level of stimulation the formulation provides always remains consistently high.

Iron Brothers Thermo Burn is not a supplement for the faint-hearted. It’s likely to be too strong for the average person seeking a pill to help them to lose weight. However, gym-goers who have become accustomed to using stimulant-rich products may find Iron Brothers Thermo Burn an attractive option.

Thermo Burn Benefits

  • Helps you to burn more fat faster
  • Increases energy and physical performance
  • Improves mood and focus
  • Boosts metabolism to provide even faster results

How Iron Brothers Thermo Burn Works

Have you ever wondered why your skin feels warm? It’s due to a biological process called thermogenesis that generates heat within the body.

Thermogenic fat-burning supplements, like Iron Brothers Thermo Burn, provide ingredients that tweak the body’s internal thermostat, causing it to run a little hotter.

This causes the body to lose extra energy as heat. When you are following an energy-restricted diet, the increased energy drain due to thermogenesis forces the body to burn extra fat.

Lots of ingredients have this ability. Caffeine is one of them. Other stimulants can do it as well but non-stimulant alternatives such as green tea and cayenne are better options because they don’t present the same risk of side effects.

That’s not to say caffeine is bad. It can be very useful for preventing fatigue and burning fat. However, most good diet pills provide no more than 100-200 mg per dose. That’s the equivalent of 1-2 normal-size cups of coffee.

Providing more caffeine than that increases the chances of side effects. Iron Brothers Thermo Burn provides significantly more. That’s never a good move.

The other problem with caffeine is, the body gets used to it, causing you to develop higher tolerance. As your tolerance increases, most of the benefits are lost. The same is true for all stimulants.

However, if you have a low caffeine tolerance, Iron Brothers Thermo Burn should help you to increase your calorie expenditure and give you extra energy to train. Just don’t be surprised if you get side effects.

The formulation should also suppress appetite, but some alternatives can provide a greater level of hunger control.

How to Use Iron Brothers Thermo Burn

The standard dose is two Thermo Burn capsules per day. You take the first one 30 minutes before breakfast or your morning workout. Presuming you do not experience any side effects, you take the second capsule four to five hours later.

Iron Brothers Thermo Burn is intended for most healthy adults, aged 18 or over but it’s not for women who are pregnant or nursing a child. Due to the gelatin in the capsule casing, the supplement is not vegan or vegetarian-friendly either.

Taking this supplement alongside coffee, energy drinks, or other sources of caffeine is not recommended.

Although Iron Brothers fails to state it, people who have existing health issues will need to get medical advice before taking a stimulant-rich supplement like this. So will anyone who would need to use Iron Brothers Thermo Burn alongside their regular medication.

Iron Brothers Thermo Burn Ingredient Profile

As we mentioned earlier in this review, Iron Brothers has changed the formulation more than once. It may change it again.

However, at the time of this review (March 2022), each capsule provided nine key ingredients:

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

Ingredient Potential

Caffeine Anhydrous (275 mg)

In addition to being an energy booster and thermogenic fat burner, caffeine offers a range of benefits that may surprise you. Among other things, it can improve memory and lower the risk of type 2 diabetes and strokes.

However, the FDA suggests consuming no more than 400 mg of caffeine per day. Two doses of Iron Brothers Thermo Burn provide 550 mg with additional stimulants on top.

Citrus Aurantium (75 mg)

Also known as bitter orange, citrus aurantium is a species of citrus fruit. It provides several stimulants. The most notable one is synephrine.

Synephrine is a popular supplement ingredient but some research suggests it only increases fat burning during exercise.

Grains of Paradise (60 mg)

Grains of paradise is a seed extract that may increase thermogenesis by converting white adipose tissue (WAT) to brown adipose tissue (BAT).

Cayenne Pepper (50 mg)

Cayenne provides the plant chemical capsaicin. Research shows it can support weight loss in a number of ways.

Capsaicin reduces hunger, increases thermogenesis and metabolism, and also converts WAT to BAT.

Theobromine (50 mg)

Theobromine is a mild stimulant. It comes from cocoa. In addition to boosting energy, theobromine also improves mood and is associated with the “feel good” abilities of chocolate.

L-Theanine (50 mg)

L-theanine is an amino acid that’s present in some species of mushroom and is especially abundant in green tea. It provides a unique form of stimulation that people describe as an “alert calm.”

Yohimbine (3 mg)

Yohimbine is a tree bark extract that’s one of the best natural treatments for erectile dysfunction (ED). Many diet pill manufacturers add it to their supplements because it also appears to increase metabolism and fat loss.

Although this is a good ingredient, it has many side effects.

Toothed Clubmoss Aerial Parts Extract (2.5 mg)

This is a strange inclusion. It’s a better fit for a nootropic supplement than it is for one for people who want to lose weight.

Some people use toothed clubmoss to treat memory problems and Alzheimer’s disease. Unfortunately, there is a lack of evidence to suggest that it works.

Bioperine (2.5 mg)

Bioperine is a brand of black pepper extract that boasts an incredibly high piperine potency. Piperine is a useful alkaloid that enhances the body’s absorption of nutrients, medicines, and supplement ingredients.

Iron Brothers Thermo Burn Customer Reviews

Some customers praise Iron Brothers Thermo Burn for its energy-boosting capabilities. Others complain about side effects. As far as reviews go, it’s pretty much an even mix of good and bad.

It’s worth noting, very few of the positive reviews are from people claiming weight loss. If you are reading this review because you are looking for a supplement to help you to lose weight, you may want to bear that in mind.

Let’s take a look at a few positive reviews.

Now let’s take a look at some reviews from people who have less flattering things to say.

Iron Brothers Thermo Burn Review Conclusion

Although this supplement may provide some users with extra energy and weight loss support, there is no guarantee it will work. With a stimulant-rich product like this, it’s all a matter of tolerance.
