What Is LeanFire XT?

LeanFire XT is a fat burning supplement that can be used by both men and women.

It promises to eliminate stubborn fat, improve endurance and increase focus.

This supplement claims to be different from other fat burners by addressing both the physical and mental angles of weight loss.

LeanFire XT is made from scientifically tested ingredients formulated in trademark blends.

It is manufactured in the USA by Force Factor LLC, a company started by two former Harvard graduates.

They manufacture different supplements for male vitality, brain health, pre and post work out formulas among others.

LeanFire XT Ingredients

LeanFire XT Ingredients

LeanFire XT has several ingredients bunched together in 3 proprietary blends.

1. Fat Incineration Weight Loss Blend

This blend contains the following ingredients:

This is a proprietary mix that is ‘highly bioavailable and jitter free’. It is claimed to help one lose fat rather than muscle, reduce BMI and control appetite.
Green Tea Leaf Extract
Green tea is rich in catechins that help speed up the body’s metabolism.1
L- Carnitine
This amino acid helps in the oxidation of fatty acids.2
Cayenne Pepper Extract
This spice increases body heat naturally which leads to faster metabolism.3
Bioperine is extracted from black pepper. It is useful in this blend as it helps the body to effectively absorb other ingredients.4

2. Metabolic Mind Matrix

This blend contains the following ingredients:

Caffeine Anhydrous
Each capsule contains 150mg of caffeine which is aimed at stimulating the central nervous system. This results in increased concentration and focus. It also suppresses appetite while giving the body an energy boost.5
L- Theanine
This compound is added to this formula to help curb the high and low effects of caffeine thus reducing jitters.

3. Pure Energy Complex

This blend contains the following ingredients:

Made from the bark of the Yohimbe tree this ingredient increases thermogenesis. It also helps the body to continue burning fat even while at rest.6
TeaCrine is a non-stimulant theacrine found in some teas and coffee. It provides energy and clarity without inducing a high.7
Other Ingredients
Gelatin, Dicalcium phosphate, Magnesium Stearate, Titanium Dioxide.

How Does LeanFire XT Work?

Force Factor uses a proprietary blend for this product.

As such we don’t know what doses have been used for each ingredient and whether they are effective or not.

Because of not disclosing this information the maker raises our suspicions on the effectiveness of the product.

As for how it works- the three premium blends formed by the ingredients work together to create ‘thermovigilance’.

Thermovigilance is not a known scientific term but a concept that the makers of this supplement have coined as a sales point.

According to them it works by increasing awareness/ clarity without spikes and jitters while providing ‘clean energy’.

The LeanFire XT formula contains caffeine which naturally causes a high then a low, especially post work out.

To counter this caffeine crash the supplement includes ingredients such as L- Theanine to calm the jitters without restricting the effects of caffeine.

As a result, you will get all the benefits- weight loss, increased energy, clarity and endurance minus unpleasant spikes and jitters.

How To Use LeanFire XT?

The manufacturer recommends taking one capsule two times a day, 30-60 minutes before your biggest meal.

LeanFire XT should not be taken within 4 hours of bedtime.

Are There Any LeanFire XT Side Effects?

LeanFire XT Side Effects

The LeanFire XT formula does not contain any banned or dangerous substances.

It does however contain 150mg of caffeine in each dose and this may cause headaches and interrupted sleep especially if taken too close to bedtime.

According to online reviews customers have experienced nausea, headaches and jitters after taking it.

LeanFire XT also contains Yohimbe, an ingredient that has mixed reviews online for having negative side effects.

Intake of other stimulants should be reduced while taking LeanFire XT as too much caffeine can cause nervousness and irritability.

This supplement should not be taken by expectant women and anyone under the age of 18years.

If you are taking other medication or have any medical conditions such as high blood pressure consult a doctor before taking Leanfire XT.

Some customers found it to work as advertised.

Sterkis reports:

“I tried it out for about five days. I followed all of the instructions but it made me sick to my stomach and I couldn’t get far from a restroom while taking it. It gave me a slight energy boost but I’ll happily drink a cup of coffee instead.”

Avery says:

“I feel like I’m in beast mode every time I take LeanFire XT. More energy to power through my morning routine, more energy to push me through the afternoon, and more energy to get after it in the gym in the evening. LeanFire XT + drinking a gallon of water each day has helped me tremendously because I have so much more energy and I just feel better overall.”

LeanFire XT Review: Should You Buy It?

LeanFire XT Fat Burner Review

LeanFire XT claims to have a secret formula that doubles fat loss.

Unfortunately we could not ascertain how well it works from its proprietary blend of ingredients.

It however can increase metabolism, energy and focus which is what you might need to work harder at the gym.

As with every product results after taking it are different for every person.

Some people report that it worked as advertised, and others experienced negative effects such as headaches and nausea.

Leanfire XT has a 14 day trial period that might be a good chance to evaluate whether it works for you or not.

You need to be careful however because taking the trial also enters you to an automatic billing program of 69.99 per month + Shipping.

If you don’t intend to continue with the product you must cancel before the 14 days are over to avoid automatic billing.

As with any other fat burning supplement LeanFire XT should be combined with a low calorie diet and exercise for any meaningful results.
