LeanFire XT Review

Since prehistoric times man has understood the truth that fire burns. And since 2009 Force Factor marketing man has tried to convince us that products like LeanFire XT burn fat, but is that true?

LeanFire XT admits that it does what a lot of burners claim to, namely;

  • • Speed up your metabolism
  • • Cut fat
  • • Increase energy

Where it attempts to set itself apart is with what it calls a Mind Matrix. These are basically ingredients to lift mood and sharpen focus for when getting in shape starts to feel like a bit of a drag.

LeanFire XT Review

Actually these are not all that rare in burners now, but a good one can still be a great help so we felt this product was worth checking out properly.

Will LeanFire XT burn fat off our bodies or just blow smoke up our … well, you get the idea.

One hint might lie in the fact that the entire formula is a proprietary blend. No individual dosage information for you the customer then, just component names and a total amount.

Why not? We’re yet to find a convincing answer to that question in all our years of reviewing supplements. Still, let’s do our best to break down the mystery stew LeanFire XT is cooking.

How Does It Work?

At a Glance

  • Fat Incineration Blend to burn fat.
  • Metabolic Mind Matrix to stimulate metabolism and focus
  • Energy Complex to sustain energy levels.

The Scores

The Scores

A number of issues here. Some with the choices and some with the dosage of the choices.

Proprietary blends prevent us knowing exact amounts but with just under 800mg in total, we can be pretty sure in many cases there’s not enough. The best burners would give green tea and cayenne pepper nearly that just between the two of them.

But not being sure how much caffeine is never great and neither is any amount of bitter orange extract. Add to that some ingredients that don’t seem to have a lot going for them clinically and there’s not a whole lot left to like.


We can’t see how LeanFire is justifying a $60 price tag. Maybe if the small portion of formula had all the very best ingredients, like a posh French restaurants, they could get away with it, but that’s not the case.

It’s not the most expensive option we’ve seen, it doesn’t got to triple digits to be fair, but it’s right in the range of some of the best burners on the market and it doesn’t come close to them in quality terms. Buy smart, that’s what we say.


If you’ve read any of our other reviews, you’ll know that in this section we’re always banging on about a testimonial section on the official website.

Well, good news and bad news folks. The good news is, we’ve got one! The bad news is it’s about as enlightening as a Goth’s interior design choices. Just a short paragraph attributed to a first name and surname initial. No more help than retail site feedback.

Speaking of which, they’re a pretty mixed bag too. Only managing 3 out of 5 stars on a couple of large websites. Many report having more energy but just as many appear to have been disappointed by a lack of results.


Proprietary blends are always going to be  black mark when it comes to trust, as it is basically the company straight up saying ‘We’re not telling.’

But proprietary blends that contain ingredients that could potentially cause side effects is even worse. Add to that a hefty cost for a pretty lightweight product and we’re not about to be giving high marks.


Force Factor are a pretty successful outfit with a range of supplements covering various aspects of natural fitness. They have a Better Business rating of A+ but we’ve heard reports of the odd customer service problem as far as charges go. On the whole though no worries about respectability.

How Do I Take It?

Users should take 1 serving initially 1 cap a day, half an hour before a meal or workout. This can be increased to 2 caps if you feel no adverse effects.

To be perfectly honest with you 1 cap or 2 caps doesn’t make much difference in the grand scheme of things. Because it’s still only one serving. Anyone who’s ever been camping knows that a fire will burn for a few hours then start to die down and then need refuelled. That’s exactly the same with LeanFire XT.

There’s no way one serving will sustain it’s fat burning peak for up to 12 hours of a busy day. That’s why most clued in burner brands favor 3-4 servings spaced out evenly over the course of the day to make sure your getting the most out of bioactive ingredients at all times.

Any LeanFire XT Side Effects?

We like all our supplements to reveal all their ingredient amounts all the time, but particularly when stimulants are involved. LeanFire XT contains caffeine, though how much we don’t know.

The devil really is in the dose with that. Enough is a difference maker, too much can cause nausea, headaches, insomnia and racing heart.

We also have Bitter Orange Extract here, which is a real concern, especially when paired with caffeine it can trigger the same effects as we’ve just talked about, plus raise blood pressure.

This could leave you at a higher risk of serious problems such as heart attack and stroke.

Where Can I Get It?

LeanFire XT is available from Amazon.com for just over $62, buying you a month’s supply.

Ingredients - In Detail

Green Tea

Green Tea

Key to any fat burner’s effectiveness is it's thermogenic profile and they don’t come much more impressive than this powerful antioxidant. Green Tea’s catechins stimulate a fat burning hormone called norepinephrine, which naturally raises the body temperature, vastly increasing the number of calories burnt.




Aliases : Acetyl L-Carnitine

L-Carnitine has consistently proved in scientific studies that it aids the efficient transfer of fatty acids into useable energy, meaning less excess gets stored. The overall impact this has on weight loss had come in for some question of late, but no one’s arguing it’ll give you a sizeable energy boost which can be put to good use in the gym.

Cayenne Pepper

Cayenne Pepper

Cayenne is one of the best natural ways of starting thermogenesis in the body. The capsaicin in this ingredient melts away extra calories by heating the body up, then expends more again as our system tries to cool back down.



Added to a fat burner to strengthen the stimulant line up because like caffeine, theacrine mainly boosts energy and alertness. Again, handy for firing you up for an exercise session, which is why it’s becoming increasingly popular in pre-workout products also.

Caffeine / Caffeine Anhydrous

Caffeine / Caffeine Anhydrous

The first burner regular. Caffeine is a great choice for two reasons; firstly it speeds up your metabolism, burning through far more fat, and secondly it provides energy to help you avoid the slumps that normally come with a low calorie diet.

The 'Anhydrous' part refers to the fact that the water is removed to leave a white, crystalline powder with concentrated potency.




DMAE is a choline molecule used as a natural way to combat cognitive fatigue or decline. Sadly the one noteable human study on this we found reported no change after 24 weeks of a daily 1.5g dosage given to the elderly. Not much work has been done on other uses or age groups, but it doesn't look all that promising.


Synephrine HCL

Synephrine HCL

Aliases : Bitter Orange Extract

Sometimes called Bitter Orange Extract, this ingredient has demonstrated the potential to boost both energy and metabolism, albeit somewhat inconsistently. It has a significant downside however, when combined with caffeine, synephrine can provoke some serious side effects and may pose significant health risk.




Yohimbe is an effective fat burner in the right dose because it blocks the alpha receptors in the brain which limit fat burning. Too much yohimbe can cause side effects such as dizziness and nausea.


Anything Missing?

In the P.R for LeanFire XT they make a big deal about how most burners forget how key the mind is to losing weight. This is true, but what about the part they forgot, the stomach?

There are so many safe and 100% natural ways to help regulate appetite now. It’s as simple as adding a decent amount of some high fiber ingredient which will expand once ingested and make you feel full. None of that in this Fire.


The name really is the most impressive thing about this product. It sounds great but look more closely and you’ll find that LeanFire XT is a bit of a damp squib, more likely to burn a hole in your pocket than anything else.
