MaxiNutrition Thermobol just doesn’t cut it by today’s standards as far as far burners go. The formula is over reliant on an ineffective ingredient – Bitter Orange Peel. This stuff doesn’t encourage fat loss, and it doesn’t make dieting any easier. Yet it commands a significant portion of the Thermobol formula. Then there’s the fact that it contains a lot of caffeine. Each serving of Thermobol contains 444mg of caffeine. Even if you split that up into 3 equal doses throughout the day, that’s still far too much for most people, especially when you notice the extra 36mg of Guarana Powder in there – God know why!
All-in-all, we don’t think this is a very good fat burner. It probably sells so well because the MaxiNutrition name is so established. But based on merit alone, we don’t know why Thermobol is still such a big seller in the UK.
Our MaxiNutrition Thermobol Review
MaxiNutrition is probably the biggest name in sports nutrition in the UK. Alongside MyProtein and Optimum Nutrition, these guys are definitely seen as the ‘default’ option when it comes to sports supplements. If you started bodybuilding in the UK in your teens, then MaxiMuscle (as it was known then) Progain was probably the first protein powder you ever used. Their protein supplements are very good quality, and the prices are reasonable. But what about their specialist bodybuilding supplements?
What is Thermobol supposed to do?
How does it claim to work?
The tagline for this product is “lean definition”. It is not a diet pill; it is a bodybuilding supplement designed for use alongside a diet and exercise program. According to the website, it is a “fat metaboliser” designed to help you achieve your “lean muscle goals”.
Users are told that they can expect the following core benefits while using MaxiNutrition Thermobol:
- Greater energy levels
- Faster metabolism
- Enhanced focus
- Greater fat loss
That is exactly what we want from a fat burner.
It would definitely be nice to see some mention of reduced hunger or help staying full for longer during a diet. This is an important part of a fat burner for us, especially when you’re coming off a serious bulking phase. But that doesn’t mean that Thermobol isn’t a fantastic fat burner still.
If it can reliably and safely boost metabolism, increase fat loss, and enhance focus during a cut, then it is a solid fat burner in our books.
But that’s a big ‘if’.

MaxiNutrition Thermobol Ingredients
Here is the ingredient list for MaxiNutrition Thermobol:
We really expected more from Thermobol considering it is a MaxiNutrition product and still one of the most widely-used fat burners in the UK.
But at the same time, Thermobol has been on the market for some time. The fat burner market evolves quickly, and since Thermobol came out, there have been dozens of products launched which just blow it out of the water.
Our main issue is the use of Bitter Orange Peel. This stuff has never been shown to work in laboratory conditions. Ever.
In our opinion, it is just useless fruit powder hyped up by the big bodybuilding supplement brands.
There’s also far too much caffeine in here for our linking. 148mg per pill, with 3 pills per day, adds up to 444mg of caffeine per day. That is an awful lot of caffeine for anybody to be adding to their existing daily consumption.
There are some good ingredients in here. But overall we think Thermobol’s weaknesses outweigh the strengths.
Let’s go through these points in a little more detail.
- Lots of chromium
- Uses good serving of Tyrosine
There are some very strong points to the Thermobol formula.
For example, we absolutely love the Tyrosine serving we get from each capsule of MaxiNutrition Thermobol.
Each cap contains 300mg of Tyrosine. That means a full day’s serving of Thermobol provides 900mg of Tyrosine.
Tyrosine doesn’t have any fat burning properties. It doesn’t increase metabolism, trigger thermogenesis, or even give you extra energy. Yet it is still a good addition to a serious bodybuilding supplement. That’s because Tyrosine has been shown to help improve focus and mental performance during times of serious mental and physical strain (ref).
It should be clear why this is a benefit in a fat burner. Tyrosine can help keep you focused on both your work and your training despite being exhausted from intense workouts and serious dieting.
If you’re anything like us, then your work definitely suffers while you cut. You get distracted (usually thinking about food). You feel demotivated and sluggish. As a result, your workouts suffer too.
The 900mg of Tyrosine we get from each daily serving of Thermobol is enough to keep you calm and focused on your work and your training throughout your cut.
- Bitter orange peel doesn’t work
- No appetite suppressant
- Too much caffeine
- Guarana is pointless – just use caffeine!
Unfortunately, we found many more things that we didn’t like about Thermobol than things we did like. We’ll go through them now in order of severity.
The thing we are most put-off by is the caffeine content. However, we will deal with that in the side effects section. Suffices to say here that 444mg of caffeine per day – on top of whatever your existing intake is – will be far too much for practically all of you. We don’t care how high you think your tolerance is; 444mg is a lot!
More on that later.
The next biggest issue is the use of Bitter Orange Peel as the main ingredient.
We’ve scoured the academic journals for hours looking for evidence to support the use of bitter orange peel – or its main active ingredient synephrine – as a fat burner.
We are yet to find a single study proving that it does a thing for improving fat loss.
There is no robust, clinical study which shows that bitter orange peel – or synephrine – improving fat loss, enhancing athletic performance, reducing hunger, or any of the other things that fat burners help us with.
As far as we’re concerned, until we see a peer-reviewed clinical trial showing that it works, it has no place in a fat burner.
Yet it is Thermobol’s main ingredient! By a significant margin too.
Each daily serving of Thermobol provides over 1000mg of Bitter Orange Peel. That is a large dose for an ingredient that doesn’t actually do anything, and one which might cause side effects! It’s a lot of orange peel to be paying for too.
Another thing that we feel compelled to point out is the use of the Guarana gimmick. Because make no mistake – Guarana is a gimmick, nothing more.
Many supplement manufacturers add Guarana to their products because people mistakenly believe that it has interesting, energy boosting properties.
They see it as a kind of ‘super coffee’, with more of a kick than regular caffeine.
But this isn’t true at all.
Guarana contains caffeine. On a gram for gram basis, a Guarana seed contains more caffeine than a coffee bean (but not by much). Yet this is completely irrelevant unless you’re planning on eating the seeds and beans. There is no difference between the caffeine found in guarana and the caffeine found in coffee once it has been extracted.
So why add Guarana See Extract (assuming this is caffeine) to a product that already contains pure caffeine?
We think the only reason anyone would do this is to take advantage of the way uninformed consumers view Guarana – as though it were some kind of magical energy kicker. It isn’t; just use pure caffeine with a clearly stated dose. And don’t fall for these gimmicks.
For some of you this final problem will be the most damning. Thermobol doesn’t contain anything to help with hunger, over-eating, or food cravings.
For a fat burner these days, that is a serious limitation!
Every single fat burner on the market today needs to have some kind of appetite-control component.
For it to be a viable bodybuilding supplement, it needs to naturally keep you full for longer without artificially suppressing your appetite – you still need to eat when it’s time to eat! The same goes for any sports-specific supplement; you can’t use anything that will effectively ‘turn off’ your appetite as you might miss your eating windows.
For it to be healthy and sustainable for the long-term, it needs to not be a ‘carb-blocker’ or ‘fat-blocker’. Some substances claim to be able to prevent these nutrients from being absorbed. We don’t necessarily believe them, but if they can, then you’ll quickly find yourself in trouble. Fats and carbs are important parts of a healthy diet – you shouldn’t block them.
Instead, we look for something that will make us feel fuller for longer, while still allowing us to eat. We ideally want something that will last a couple of hours before gradually wearing off to allow us to feel hungry again.
So we look for things like glucomnannan; the ingredient used in Instant Knockout. This expands in the stomach to make your meals feel larger.
Thermobol contains none of the above.
There is nothing in Thermobol to help you get through your diet without serious hunger pangs, food cravings, and periods of severe temptation. This is pretty unacceptable in a modern, premium fat burner.
Will MaxiNutrition Thermobol Cause Side Effects?
The one thing we are yet to really talk about is the side effects you are likely to experience while using Thermobol.
Generally speaking, MaxiNutrition are an extremely trustworthy company. We never expected to find any nasty synthetic chemicals, pro-hormones, or banned substances in here, and we didn’t.
However, there is good reason to be very careful while using Thermobol – the high caffeine content.
Each capsule of Themrobol contains 148mg of pure, concentrated caffeine.
That is roughly equivalent to two shots of regular espresso, or a grande caffe lattè from Starbucks.
We don’t care how large your caffeine tolerance is; adding an extra three caffe lattès from Starbucks to your baseline caffeine intake per day is going to have some kind of impact.
More than likely, you’re going to experience one or more of the following side effects (even if you don’t consume any other caffeine):
- Elevated heart rate
- Shortness of breath
- Difficulty concentrating
More long-term, you’re looking at insomnia, dependency, and an elevated risk of heart disease – that is, if you keep that kind of consumption up for a while.
We recommend cutting right down on the caffeine from tea and coffee if you’re going to use a fat burner like MaxiNutrition Thermobol. We also recommend dropping any other supplements that contain caffeine entirely while using this fat burner.

Please remember the following facts while reading our supplement reviews:
- We are not doctors
- This is not medical advice
We don’t know anything about you, your medical history, your current medications, or anything like that. You must do your own research and consult with a medical professional before using any fat burners whatsoever. All we can do here is highlight the most obvious dangers for the average user.
MaxiNutrition Thermobol Review Conclusion – Worth A Try?
For us, MaxiNutrition Thermobol just comes up way short of our expectations.
Its main ingredient – by a significant margin – is totally unproven. We actually think bitter orange peel is worse than unproven; it’s a total dud. In buying Thermobol, you’re paying good money for a formula that is largely useless dead weight.
There’s also way too much caffeine in Thermobol for us. The 148mg per capsule seems fine, but a daily serving is three capsules, or 444mg in total. That is going to cause side effects no matter how high your tolerance.
Thermobol does have redeeming features of course. It is one of the top selling fat burners in the UK after all.
We get a very generous serving of Tyrosine, which will help keep you focused at work and at the gym.
We also get a good serving of green tea, and a sizable daily hit of chromium to help with blood sugar control.
But this doesn’t make up for the serious flaws in the formula.
All-in-all, if you want faster fat loss, better muscle retention, and an all-round more effective cut, you can do a lot better than Thermobol. It might have been a good supplement for a bodybuilder in the past, but today it can’t compete with the big boys.
