The weight loss supplement industry is worth billions of dollars in the U.S. alone, and it seems like these numbers won’t be going down anytime soon.

This trend comes as no surprise, considering that a staggering percentage of the population is struggling with their weight.

Companies have leveraged this need by producing countless products that claim to help with fat burning, weight loss, and appetite reduction.

One of them is Lean-XT, a fat burner, weight loss supplement, appetite suppressant, and metabolism booster all in one.

After a two-month trial, here’s my honest review of this product.

What Is Lean-XT?

Lean-XT

Lean-XT is a thermogenic weight loss supplement formulated for both men and women.

It’s made with all-natural ingredients and is heavily marketed as a caffeine-free and stimulant-free fat burner that preserves muscle mass instead of destroying it during the fat-burning process.

With its mix of science-backed ingredients, these vegetarian-friendly diet pills can suppress appetite, assist in weight loss, and help you maintain a lean physique.

This product contains no artificial fillers or dyes.

It is manufactured in a state-of-the-art cGMP facility in the United States that adheres only to the strictest quality control guidelines.

Its maker, Jacked Factory, designed Lean-XT to be taken with other thermogenic fat burners for maximum effect.

The brand places great value on delivering only the safest, reasonably-priced, and research-supported supplements to athletes.

Lean-XT Ingredients

Supplement Facts of Lean-XT
  • Acetyl L-Carnitine HCL (750 mg): Acetyl L-Carnitine is the primary fat-burning ingredient of Lean-XT.
    This component transports fatty acids into your cells’ mitochondria, which then burns these fats and transforms them into usable energy [1]. Acetyl L-Carnitine is also noted for its effect on improving memory, thinking, and alleviating nerve pain. Some users were happy as they started seeing positive changes in their body after finishing just one bottle, which may have been caused by this popular thermogenic.
  • Green Tea Extract (500 mg): Green tea extract is best known for its high antioxidant content, which is comprised mostly of catechins. Of the catechins found in green tea extract, the epigallocatechin gallate is credited as the one most beneficial to human health. Studies show that it helps with weight loss and body fat reduction, especially when taken with a specific amount of caffeine [2]. However, these effects aren’t consistently observed when it’s taken on its own. Since Lean XT is a caffeine-free fat burner, our dietician pointed out that green tea extract acts as a mild stimulant to increase focus and alertness.
  • Coleus Forskohlii Root Extract (150 mg) + Forskolin (30 mg): Coleus Forskohlii is a tropical plant native to India that’s been used since ancient times as herbal medicine to treat various disorders. Forskolin is isolated from this plant’s roots and is known for its potential benefits in accelerating fat loss in your body.
    A clinical trial on obese men showed that forskolin could significantly decrease body fat percentage and fat mass in the body [3]. Researchers also observed a rise in their testosterone levels, which promotes muscle mass growth. Most of our clients who tried Lean XT had good results with building lean muscle mass, but it falls short on supporting fat loss.
  • Bioperine Black Pepper Extract (5 mg): Bioperine is the active ingredient in black pepper that contributes to its spicy taste. This component offers many benefits, but it’s best known for its ability to increase the absorption of nutrients in your body, which means you get more out of the nutrients you consume. This is why it’s a popular ingredient in many dietary supplements.
    Bioperine is also said to boost metabolism by enhancing thermogenesis in your body.

How Does It Work?

weight loss

Jacked Factory touts the Lean-XT as a stimulant-free fat burner that supports weight loss with all-natural ingredients.

It does that in two ways. First, it suppresses your appetite, thereby decreasing your daily calorie intake.

Second, it boosts your metabolism, which then helps your body burn more calories daily.

While there are many diet pills on the market that offer the same benefits, what sets Lean-XT apart is its ability to preserve muscle while dieting. 

This quality makes it an attractive option for bodybuilders and athletes who want to lose weight and simultaneously maintain a sculpted physique.

How To Take It

Lean-XT

Jacked Factory recommends that new users take 1 capsule of Lean-XT per day for three days to check for any adverse reactions.

If you encounter no tolerance issues, you can then switch to the regular dosage, which is two capsules with a glass of water 1-2 times per day, 30 minutes before meals or with meals.

For best results, the company stresses the importance of sticking to a healthy diet, exercising regularly, practicing healthy lifestyle habits, and drinking plenty of water throughout the day while taking this supplement.

“You have to think it before you can do it. The mind is what makes it all possible.” - Kai Greene, Pro Bodybuilder

LEAN-XT was designed to be stacked with BURN-XT and/or LEAN PM—two other fat burning supplements offered by Jacked Factory.

If you want maximum results, you can take Lean-XT during the day and LEAN PM before bed.

How Much Does Lean-XT Cost?

Each bottle of Lean-XT by Jacked Factory is reasonably priced for a serving of 60 pills. at $30 It’s even cheaper the more bottles you buy.

It’s actually on the lower end of the price range of popular fat burners which can go as high as $70. It’s also cheaper the more bottles you buy.

Pros
  • Supports appetite suppression
  • Gives a great boost of energy during exercise
  • The company provides great customer service
  • Vegetarian-friendly, non-stimulant fat burner
Cons
  • Some users reported gaining weight while taking this supplement
  • Might cause feelings of bloatedness

Any Side Effects?

headache

Here are this supplement’s possible side effects based on its three primary ingredients:

Acetyl-L-Carnitine is likely safe for most adults, but it can cause some side effects, including an upset stomach, nausea, vomiting, dry mouth, headache, and restlessness [4].

Green tea extract, when taken for a long time or in high doses, can cause side effects such as headache, nervousness, vomiting, diarrhea, irregular heartbeat, tremor, heartburn. Most of these responses are caused by the caffeine content in green tea extract [5].

Forskolin hasn’t been studied thoroughly, but its possible side effects include flushing, fast heartbeats, low blood pressure, upper respiratory tract irritation, cough, tremor, restlessness, and headache [6].

To prevent these adverse reactions, be sure to take this supplement within the recommended dosage.

Even when I take this supplement during breakfast or lunch, I still get bloated and gassy on most days, which is quite disappointing for a stim-free and all-natural fat burner.

Customer Reviews

leanxt feedback

Lean-XT got mixed reviews from users. Let’s take a look at some of the glowing feedback.

“Lean-XT has helped me with the hunger pangs. I still feel a little hungry, but not to the point where I feel nauseated. So far, I have lost 7 pounds in the last 20 days without feeling hungry all the time!” - Kahlora C.

“I’m on my second bottle, and I’m very happy with this product. I experienced an increase in energy with it, which has resulted in more effective workouts! It hasn’t really suppressed my appetite, but I’m also taking less than the recommended amount, to be fair. I would recommend it.” - Holly R.

Despite delivering promising results for some customers, these negative feedbacks are still worth noting.

“Can’t say I’m a fan of this. Once I started taking this supplement, my appetite increased rapidly. I actually gained weight while taking this. I don’t recommend this at all.” - Tamara L. 

“I had to stop taking these as they started messing with my stomach and bowel movements.” - Abby J.

“Unfortunately, these pills did nothing to suppress my appetite. I actually felt hungrier while taking them. I also often felt sick to my stomach.” - Dani M. 

“I had to stop taking this product after about three days because they gave me diarrhea. It took about another week for me to get back to normal.” - Nikki P.

Fat Burner Alternatives

PhenQ

As one of the most popular and effective fat burners today, PhenQ is a 5-in-1 weight loss solution that includes the patented α-Lacys Reset® formula to promote fat burning and block fat production.

Unlike Lean XT that contains green tea extract and L-carnitine to boost metabolism, it uses caffeine and turmeric, as well as appetite-suppressing ingredients like nopal and chromium to support a healthy and sustainable fat loss.

While Lean XT focuses on burning fat while preserving muscle mass, PhenQ is a 100% vegan-friendly fat burner suitable for regular people who want to lose excess fat, curb cravings, and boost energy levels with the help of one pill a day.

LeanBean

Similar to Lean XT, LeanBean is an all-natural and stimulant-free fat burner that aims to burn more calories and better regulate appetite without the usual jitters and headaches.

It contains scientifically proven ingredients like green coffee bean extract, turmeric, and glucomannan, as well as added vitamins and minerals, which you won’t see in Lean XT.

The main difference between the two is that LeanBean is a 100% vegan-friendly fat burner specifically formulated for women to have a smoother and more efficient weight loss. It comes at a higher price though, and you would need to take 6 capsules per day compared to just 2 with Lean XT.

Instant Knockout

Instant Knockout is one of the first weight management supplements designed for bodybuilders and performance athletes.

Unlike the stimulant-free Lean XT with a short ingredient list, it contains caffeine and glucomannan to boost metabolism and suppress appetite, as well as L-theanine, cayenne, black pepper extract, and several vitamins and minerals for better weight loss support.

It also differs from Lean XT as it has a relatively high dose for each ingredient, which is probably why it has been proven to work with both athletes and active people who want to shed some pounds and get a shredded look.

Lean-XT: Do I Recommend It?

The Lean-XT by Jacked Factory stands out as a stimulant-free fat burner, but I found that it had little to no effect in suppressing my appetite and supporting weight loss.

I also would have to agree with the negative review saying that the product did cause stomach issues. In the two months that I took it, I noticed that I felt gassy and bloated most of the time.

I’d say this supplement gave me a general feeling of unwellness, and that’s fairly disappointing, considering that it also didn’t give me the results I was expecting.

What I would recommend instead is PhenQ. It’s also a fat burner that can effectively suppress appetite and speed up your metabolism.

  1. Agreed. I followed the instructions while incorporating exercise and diet, but I did not see any of the stated benefits yet. It helped with my feelings of hunger though.

    1. You might want to try PhenQ and see if it works for you. Hoping for the best in your journey!

  2. I just received my first bottle of Leanfire XT, can I stack it with CLA and L-Carnitine?
