My Maxi Nutrition Thermobol Lean Definition Review Fat Burner Review First Look

Fat burner supplements can be an effective way of increasing calorie expenditure to help you create that calorie deficit.

With this in mind and the warm summer sun, most people can only think about that vacation.

However, if you are worried about how you look on the beach you may wish for a bit of extra help to curb your appetite and burn more calories.

So, if you have increased your workout, cleaned up your diet and still want something else a fat burner could be for you.

Thermobol Lean Definition is from Maxi Nutrition, formerly Maxi Muscle.

They have a good reputation and work alongside sporting bodies as well as many professional sports teams.

Therefore we trust them.

Or at least we should. The branding and packaging looks good, well designed and considered. It is all very professional.

What can a fat burner really do?

You may well be surprised actually.

The idea that an effective fat burner just magically makes your waist smaller is far from the truth.

However, only the effective fat burners contain a number of ingredients in correct doses that work harmoniously and through a number of outcomes help you lose fat mass, not muscle.

Their benefits include, but are not limited to:

  • Increase energy – This will help you be more active and stimulate you for effective workouts
  • Thermogenic – These ingredients will increase the temperature of your core which increases calorie expenditure
  • Appetite control – The ability to feel fuller and not to fall for sweet, calorie laden treats

As a result I tend to supplement my exercise regime with a fat burner supplement.

I have found Instant Knockout to offer the best results and as a result I try to use that daily.

Initial Summary




Six effective ingredients



Low doses

Bitter Orange can be dangerous


Who are Maxi Nutrition?

I bought my first supplement from Maxi Muscle.

Years ago Maxi Nutrition was called Maxi Muscle. Since then it has been bought out by the GSK giant.

In response to the changing market for sports supplements they changed the name to reflect the wider audience.

However, years ago Maxi Muscle was founded by a man called Zef who launched the brand aimed at bodybuilders back in 1995 with just a few thousand pounds.

Since the sale to GSK for around £160 million the brand was polished up and developed to attract more people.

As a result Maxi Nutrition is almost a household name.

For me personally, Maxi Muscle was the first supplement brand that I encountered being advertised on buses and trains.

It was my first supplement purchase too, a tub of orange flavored Cyclone.

What are the claims for Thermobol?

Maxi Nutrition have put time and consideration in to the design.

So does this translate to the product?

The aims are clear and simple:

  • Increased energy metabolism
  • Increased focus

Thermobol Ingredients: The Science


– Thiamine (Vitamin B1)

Thiamine is required by our bodies to properly use carbohydrates which are then available as a quick source of energy.

There’s evidence from studies that have shown that combining B1 with B5 doesn’t actually increase or improve physical performance as previously suggested.

– Biotin

Biotin is an important component of enzymes in the body that break down certain substances like fats, carbohydrates, and others.

Studies have shown that Biotin can interfere with clinical results regarding hormones.

– Caffeine

This can assist with endurance, tested athletes saw an edge from caffeine in scientific studies.

In some trials, the stimulant boosted athletes’ speed.

In others, it helped them last longer before they spent all their energy.

Caffeine also raises the metabolism which means you burn more calories.

Some studies show that it can curb soreness after exercise, too.

This means you could get back to your training sooner and training means more calories burnt.

Caffeine is present in all 3 of our Top Fat Burners.

– Tyrosine

Tyrosine is taken for depression, attention deficit disorder (ADD), attention deficit-hyperactivity disorder (ADHD), the inability to stay awake (narcolepsy), and improving alertness following sleep deprivation.

It is also used for stress, Parkinson’s disease, Alzheimer’s disease, chronic fatigue syndrome(CFS).

– Vitamin B12 

B12 is a vital ingredient that has show to have many benefits. These include improved cognitive function.

B12 fights fatigue, muscle wastage, it boosts mood, improves cognition. This also improves metabolism and food digestion.

Studies have shown that those lacking in B12 scored lower in cognitive testing.

With further analysis demonstrating positive effects against cellulite.

B12 Gives you more energy and boost your metabolism, helping you shed unwanted pounds.

Ensure you are not deficient in Vitamin B12 so you can do that quick 10 miler at 5am…

– Chromium

Research suggests that chromium might improve weight loss in some people who are overweight or obese.

It also helps move glucose from the bloodstream and in to the cells for energy.

– Orange Peel

This is often referred to as Citrus Aurantium and Bitter Orange.

At present, Citrus aurantium may be the best thermogenic substitute for ephedra. However, more studies are needed to establish this definitively.

Research suggests that orange peel can be unsafe when taken as it may increase the likelihood of heart problems.

Bitter orange, particularly when taken with stimulants such as caffeine or caffeine-containing herbs, increases the risk for high blood pressure, fainting, heart attack, stroke, and other severe side effects.

There are reports that bitter orange can trigger headaches, including migraine and cluster headaches, in some people.

Bitter orange can cause sensitivity to the sun. Wear sunblock outside, especially if you are light-skinned.

– Green Tea

A well known to have many powerful health benefits. Clinical studies suggest that green tea extract may boost metabolism and help burn fat.

One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese.

Some researchers think that substances in green tea known as catechins are responsible for the herb’s fat-burning effect.

It has been shown to help lose almost 5% body weight over a three month period.

Green tea extract is found in many a good fat burning supplement.

– Paullinia Cupana (AKA Guarana)

Studies note that 75mg guarana (9mg caffeine) was able to enhance cognitive scores related to memory and reaction time with a subsequent dose-response study noting that 75mg was more effective than higher (150-300mg) and lower (37.5mg) doses.

– Pantothenic Acid (Vitamin B5)

Pantothenic acid, as with other B vitamins are able to convert your food in to energy.

They’re also able to help you body use fats and proteins effectively, notwithstanding the creation of red blood cells which carry oxygen to your muscles.


Known to boost metabolism,  studies of cayenne pepper show that it causes the body to produce extra heat and burn more calories for fuel.

This is found in our favorite fat burner Instant Knockout.

Thermobol Directions

Take one tablet three times daily.

It is also better to spread the pills out over the course of the day rather than take them in one sitting.

That way you maintain a high level of the thermogenic ingredients working to increase your metabolism.

If you get too much of certain ingredients, that what the body doesn’t need at the time will be wasted and you will not feel the benefit.

Therefore, if you have a massive dose of Zinc yet your body is still processing and utilizing Zinc from a meal you’ve recently had or a drink it will not process any extra that is not required.

What the body doesn’t require at the time will let it pass.

Thus, a higher chance of waste and less benefits.

Thermobol Serving

Three tablets per day amount to just over a total of 2674mg.

This is less than what you would find in the best fat burner supplements.

Thermobol Price

$39 / £30 – A fair price.


There’s seven stand out ingredients that work.

These are mainly all related to weight loss, based upon the studies.

So let’s hit the fat burner supplements first:

  • Caffeine
  • B12
  • Chromium
  • Cayenne
  • Green Tea
  • Tyrosine
  • B5

Caffeine can help with focus and helps burn extra calories while also improving sports performance and recovery.

B12 can help reduce cellulite, improve cognitive function and metabolism.

Chromium helps release energy from glucose and research shows that it improves metabolism.

Cayenne is a powerful thermogenic which contributes to an increase of core body temperature which burns more calories.

Research shows that Green Tea can improve cognitive function and burn more fat.

Tyrosine helps fight fatigue so you can get up for the gym in the morning.

B5 uses fats while producing red blood cells.


Low doses add uncertainty.

Some ingredients are dosed highly which is encouraging. But then others are very low.

And there’s a lot of risk concerning Bitter Orange…

B1 contributes to energy release from carbohydrates, but offers no performance benefit.

Biotin can break down fats, but it can also mess up clinical readings regarding hormones.

Guarana is not dosed adequately to be optimal.

However, it is these low doses of some ingredients that just do not stack up.

For instance, the following ingredients are not dosed highly enough:

  • B12
  • Biotin
  • Chromium
  • Cayenne
  • Guarana

What Improvements Could Be Made?

Some doses need to be increased.

And some need to be replaced with better, proven ingredients.

This fat burner would be complimented by including the following:

Without any of these, this will not have the maximum effect on fat loss.

Any unwanted Thermobol side effects?

There’s a big risk with at least one ingredient.

Bitter Orange has a few unwanted side effects that can be life threatening including cardiovascular failure, headaches and even sun burn.

The Tyrosine can cause issues, too…

It can be the reason for insomnia, heartburn, restlessness and can worsen thyroid problems.

My Maxi Nutrition Thermobol Lean Definition Review Conclusion

What could be possibly wrong with Thermobol?

In many respects, several to be exact, this offers some great benefits.

However, it is then let down by low doses. Some really low doses which surprises me.

Plus there’s also a couple of risks with Tyrosine and Bitter Orange.

Final Thoughts?

It is not quite as optimal as some other fat burners on the market.


I have seen Thermobol on eBay cheaper, is it legit?

Counterfeits are common place and many ‘shops’ claim to be official stockists.

Always buy direct to be sure.

Is it safe to buy from Amazon?

Again, I would only buy direct to ensure quality and that its genuine.

What if I do not like it?

Tough shit. The returns policy only applies to unused and unopened products within 30 days.

Is Thermobol like Ephedrine?

No. Ephedrine can be unsafe.

Thermobol helps increase your energy levels so you are more likely to hit the gym rather than sit in front of the TV.

Is Thrmobol safe and legal?

It is legal but there are a number of health concerns.

Can both males and females benefit from Thermobol?

Yes, but Bitter Orange can be dangerous.

Thermobol Rivals

Let’s see what other best rated natural fat burner supplements are pitched against Thermobol.


hourglass female fat burner

Hourglass may scream ‘female fat burner’ to you, and you would be right.

This is directed and marketed at women.

There is nothing wrong with that. I am more concerned with the ingredients, doses and overall effectiveness than a name or branding scheme.

Hourglass is new to the shelves and is making noises for all of the right reasons.

It is darn effective at helping you lose unwanted fat mass.

Check out the new girl on the block and feel the benefits.

  • Three ingredients of a total of twelve are not proven to cut fat

Lean Bean

Okay, Lean Bean may look extremely effeminate, and you would be correct. Its color scheme is all directed at women, that said, I love a pink dress shirt.

However, if you look past the pink and the heart logo you will find an effective fat burner that is suitable for both men and women.

This offers some stiff competition that look to take Hourglasses pole position.
