Lean XT is a weight loss supplement that is supposed to help increase the speed of your metabolism and reduce appetite, but there is no real evidence it will work as described. Although it contains some interesting ingredients it is all a bit untried and unproven, with the major ingredient Acetyl L Carnitine not really relevant to weight loss. The customer reviews will convince some customers to buy, but you should be aware that many of the positive comments posted on Amazon USA appear to be fake.
Many customers have reported side effects, including nausea, upset stomach, headaches, jitteriness, constipation, gas, and bloating.
Other side effects may include vomiting, restlessness, fishy odour, facial flushing, increased heart rate, pounding heart, low blood pressure, diarrhoea, tremors, and dizziness.
Buy from the official Jacked Factory website and Lean XT costs $29.99 for 60 capsules. Although this is described as 1 month’s supply, use as recommended and this will only last 15 days.
The company only accepts PayPal as a payment method. You can get a 15% reduction if you agree to follow Jacked Factory on Facebook Messenger. Shipping costs are not provided.
You can also buy Lean XT via Amazon USA for the slightly cheaper price of $24.99.
Lean XT is a weight loss supplement designed for both men and women, with the idea of helping you lose weight by increasing the metabolism and reducing your appetite.
The principle ingredient is Acetyl Carnitine. This is a form of the amino acid L Carnitine, which is made naturally in the body as well as obtainable by diet. Acetyl carnitine helps the body produce energy, and is important for the muscle movement and other bodily functions. It is also often taken for improving brain function such as memory in elderly people.
The next ingredient is green tea extract. Green tea is a source of some powerful antioxidants, most notably epigallocatechin-3-gallate (EGCG) and research suggests that this can increase the speed of the metabolism, and as a consequence improve weight loss if used as part of a diet and exercise regime.
The third active ingredient of Lean XT is Coleus Forskolii – out of which a natural chemical called Forskolin is derived. The claims for Forskolin are that it stimulates a molecule in the body called cyclic adenosine monophosphate (or cAMP), which is an important chemical messenger in the body that may help mobilise fat and glucose reserves thus helping fat loss.
The final component of this supplement is BioPerine, a branded black pepper supplement. This may help increase the bioavailability of the other ingredients, making them more easily absorbed and more effective in the body. Check out the ingredients tab to find out more.
Lean XT is advertised as stimulant free. We find this surprising because Green tea contains caffeine. It could be that the form of green tea used here has been decaffeinated, or that the caffeine is simply undisclosed.
According to the product information, you can stack Lean XT with Burn XT, a weight loss supplement that does contain high levels of stimulants, and in our opinion is likely to cause side effects because of this.
Factory Jacked is supplements company that operates solely online. It is probably based somewhere in the USA, but the company location is not disclosed so there is no address or no contact phone number.
However, you can contact Factory Jacked via social media including Facebook, and the company seems keen to engage with you via Facebook Messenger. If you follow Factory Jacked on Messenger, you can qualify for 15% price reduction off your first order.
There are seven key points about this supplement:
We like that this supplement is manufactured in the USA and complies with GMP (good manufacturing practice) regulations. We also like that it is aimed at men and women, and comes with a money back guarantee. However, we would have liked to have seen some clinical evidence regarding the claims that this supplement works as described.
It might do something, but it’s all a bit unproven and confusing. Principle ingredient Acetyl L Carnitine is not known as a weight loss aid, and although it may benefit some conditions such as age-related memory loss or male infertility, we cannot see it having much application to weight loss.
Green tea is by contrast often included in weight loss supplements. Clinical research has found that green tea has proven health benefits, and the antioxidants (ECGC epigallocatechin-3-gallate and polyphenols) found to have anti-obesity and fat burning properties because of the effects upon the metabolism.
According to some clinical investigation, Green tea combined with resistance training may lead to a decrease in body fat. Other clinical research suggests it combines well with caffeine. We would suggest that caffeine AND resistance training is likely to lead to the best results, but on its own, we cannot see the green tea in this supplement really causing weight loss as claimed, especially if it has had the caffeine removed.

Some people are touting Forskolin for weight loss because it may stimulate cAMP pathways, leading to increased mobilisation of fat stores where your body uses existing fat stores for energy. Research is in early stages but looks promising. That said most testing has looked at 50mg as an effective serving size, so this supplement does look a little underpowered.
One test carried out by the University of Kansas found that taken 50mg of forskolin a day over 12 weeks led to 9lbs weight loss in participants. Other smaller studies have shown general benefits to weight loss. Forskolin may also widen blood vessels and produce a stronger heart rate, as well as lower blood pressure.
Forskolin is certainly a promising ingredient, but it requires better quality and more extensive evidence to prove it one way or another. Source

Lean XT may cause side effects and some customers have mentioned these. The most common adverse reactions mentioned by customers are as follows:
Other side effects may include:
There are hundreds of customer reviews for Lean XT on Amazon USA. But the downside is that Jacked Factory is known for posting fake customer testimonials in order to create a positive impression. This pattern is repeated here and it is hard to pick out the few genuine reviews from the mass of fake comments.
The featured positive review appears to be left by a genuine customer,
These capsules do work. I took 2 every morning and that was enough to suppress my appetite all day. There were no side effects. I just ordered another bottle and will continue to take these until I reach my goal weight. I’m so happy I found these!!
We found a few more genuine looking reviews but it was like looking for a needle in a haystack as we waded through the 600 plus positive reviews. Here is an example of one genuine looking customer review.
On day 3 so far I take it on an empty stomach and in 30 mins I’m not starving I actually need to force myself to eat it’s that good! It doesn’t make you starve it just my makes you eat smaller portions. Mix this with cardio and a good diet and weight training I’ve lost 2 pounds since starting it. Highly recommend.
This customer combined Lean XT with other Jacked Factory products and still lost no weight.
With diet and exercise this product did not work! a am a fit active male who wanted to burn 5-7 lbs this product did not accomplish this goal i was able to lose 1 lb in a month with regular diet and exercise this product when combined with other Burn XT and Lean PM did not meet the promise of actual weight lose or burn!
This customer was equally disappointed.
I’ve written a review on the fat burner XT which this company advices to stack with these lean pill, I’ll say it again and I’ll take it to the bank. They are trash. You have a better chance on losing weight eating tic tacs than these pills…
This man felt the weight loss effect wore off quickly
Worked well the first week. I felt and looked slimmer. But after that it didn’t do anything for me.
Some people experienced side effects such as this customer,
This product has decreased my energy, made me bloated, and has produced no positive results for my weight. I’ve had other symptoms that I don’t want to write about until I have stopped taking these pills. If they go away now that I’m quitting this product, I’ll update my review to specify them. I wasted over $100 on these products because of my naive optimism and their multi-bottle discount. Don’t make the same mistake.
There is an advertised guarantee, but there are no details about how to claim it. Here’s what the company says about it,
We stand behind Lean XT and guarantee your satisfaction. If for any reason at all you aren’t completely satisfied with your results from this fat loss & sleep support supplement we will work to resolve your concern or arrange for a full hassle-free refund on your purchase.
You can buy Lean XT via the official Jacked Factory website. It is also on sale via Amazon USA.
We do not rate Lean XT very highly. In our opinion, the ingredients profile seems ineffective for weight loss, and we cannot see this supplement working as described. In addition, we never like companies that use false feedback on Amazon as a way to encourage other customers to buy. It is hard to spot, but we do wish that Amazon would crack down on this practice which is just misleading and basically fraudulent.
Lean XT is not the worse supplement on the market, and who knows it may have a slight effect for some people especially if combined with a healthy diet and exercise plan, but in our opinion, there are far better weight loss supplements on the market.
Overall, we do not recommend Lean XT to the Watchdog readers.
