Product Information



Nearly every fat burner claims to deliver the same benefits: increase thermogenesis, boost metabolism, and intensify the body's demand for energy so that stubbornly stored fat can be destroyed. But too many stop there. They load you up with high-stimulant energy and forget completely about the cognitive component - the mind-body connection critical to helping you reach your goals.
LeanFire™ XT is different. It considers the real needs of your body and mind as you work to burn fat and sculpt a new physique, producing clean energy while helping to reduce the nervous anxiety that too often accompanies even the best endurance boosts. It contains an explosive fat-burning thermogenic complex, unlike anything you've probably experienced, but the real magic can be found in the unrivaled Metabolic Mind Matrix.
Thermogenesis, at its core, is about raising your body's temperature to trigger and accelerate fat oxidation. But as anyone who works out knows, burning fat is more than simply a physical challenge; it's as much mental as it is physiological. A boost in energy should be paired with improved focus, premium clarity, and peek awareness to be truly useful. And that's what LeanFire XT is all about.
So stop settling for "just another fat burner," and let LeanFire XT show you how the proper dosages of hand-picked, scientifically engineered thermogenic intelligence ingredients can make a difference in your workouts.

Very satisfied!!
I read a bunch of mixed reviews prior to trying this product. I can honestly say I am very pleased with what it delivers. I get anxious naturally so I was reluctant about how it would make my heart feel. I don't get any jitters, no shakiness, no anxiety attacks or feel amped up on too much caffeine. I will say that the other day, I drank 2 glasses of coke after taking this, and at that point, I personally felt a little jittery and anxious. So if you have sensitivity to taking too much caffeine, dont mix them together. Moving on... I don't necessarily feel the "laser focus energy " feeling that all of the advertisements speak of, but everyone's body is different. Most importantly, I am consistently losing a half pound to a full pound a day. And this has happened by only taking ONE pill a day. (I have a history of chronic insomnia, so I'm a little reluctant to take 2 a day). I have not gotten back in the gym yet, so my results have purely been from just taking ONE pill a day, and my calorie intake being significantly lower. I have a goal of about 15 pounds to lose, so hopefully I can achieve that in a month's or so time. I have been very happy with what this product has done for me.

Wasn't all that.
I ordered a bottle because the commercial over the radio made it seem the these were amazing. I took one and it didn't make me feel energized how some people say it does. I took It town was suppose too. I did feel hungry all day like I couldn't get full. The next morning I felt like I had a hangover, my head still hurts and it's almost 7pm. I do not recommend taking these. But people have different side effects so to each their own I guess..... but these didn't work for me. I'd much rather take the Finaflex they work 10x better :)!

Both my partner and myself like this product, I only take one a day, and its not an effect like most pills similar to,this do not have any heart racing. No crashing, have a nice healthy energy level that lasts and lasts. And my body gets flushed out good from the water loss and intake of more water as well, I want to drink water when I take it. Win win, its almost like a body cleanse.

Good Product, Effective
This product is very good and effective. I do Crossfit a 5-6 times a week and was looking for something to help me shed the water weight I tend to retain. I take this before eating and it has definitely helped me shed this weight while not jeopardizing my health and overall well being. It doesn't make my heart race, but gives me good energy. I can feel it working because I sweat more throughout the day, which isn't a bad thing.

Not effective for high caffeine consumers
I tried this product based solely on the hourly advertisements on Pandora and used it for two months. As background, I already consume large amounts of caffeine, including 4 cups of black tea and 2 Diet Mt. Dews daily, so my caffeine tolerance is higher than average. Taking 2 pills per day made no noticeable difference, either in fat burning, weight loss, heart rate, or energy. In fact, I can take a pill and then take a nap 2 hours later without a problem. I do not recommend this product for those with high caffeine tolerances.

Acne Breakout like Crazy
I haven't had this kind of an acne breakout in months. My entire face has broken out and I just felt so pent up with energy in the worst way.

A shopper on Jan 6, 2017
BEST ANSWER: Yes it works very well. I have lost almost 20 pounds. I am dieting and drinking lots of water etc but I love it. When I first started taking it, it did give me the jitters a bit but after about a week that dissipated quickly.
I usually work out around 9:30 at night. Thinking about purchasing but afraid I might not get some sleep afterwards. How long does this take Effect?
