The results of my research into Slender X were somewhat surprising. Here at DietSpotlight, we did one of our thorough reviews, scrutinizing the ingredients, side effects, level of customer service and scientific studies. We also read countless user comments from all over the internet. Lastly, we compressed all of the information we collected in order to give you the facts you actually need.

What is Slender X?

First of all, Slender X is an over-the-counter supplement. The ingredients include yerba mate and green tea leaf extract. You simply take this tablet formula daily with water. It’s supposed to help suppress appetite, boost metabolism, reduce food cravings and elevate energy levels. No special diet or exercise is required.

It’s unclear when Slender X was initially released. It’s made by UK-based supplement company Lifes2Good. Although the official website doesn’t sell the product, some third-party retailers do. We like the use of some natural ingredients and that we found some positive feedback, but read on…

Slender X Reviews – “Any Positives?”

One issue we have is the negative user reviews. “After doing some research, we discovered several discouraging customer comments posted on the web for Slender X weight-loss pills. This is something that should not be overlooked,” mentioned our Research Editor.

One customer stated, “Slender X does not do anything. Another caffeine diet pill. It is useless in my opinion.”

However, a different user commented, “Started taking Slender X, along with diet and exercise. It gives me some extra energy.”

Another posted, “No Slender X side effects at all. I like this product. It reduces my food cravings.”

Lack of Availability – “Not a Good Sign”

Another concern is lack of availability. For instance, one person reported, “Slender X has clearly been taken off the market. No website or anything available.”

But, a different user had this to say, “Found Slender X through a third party dealer. It cost me $50.”

“Used Slender X for about one month. It’s not too bad. Has some caffeine to reduce appetite,” posted another.

According to our research, if there is a certain facet of a diet pill or weight-loss product that is very concerning (negative user reviews, lack of availability, high price) the odds of real results that last are not good. This means if Slender X does in fact lead to all sorts of discouraging customer comments, this could be a serious dilemma.

The Science – “Any At All?”

We appreciate that Slender X contains some green tea and caffeine. Together these ingredients have been shown to boost metabolism. On the other hand, if you cannot find this diet supplement for sale anywhere, it’s not going to help you lose any weight.

The Bottom Line – Does Slender X Work?

Now the moment you’ve been waiting for. Here is our bottom line on Slender X weight-loss pills. To begin, we appreciate that this formula is all natural. It’s also good to see that you can use/take this diet supplement anywhere. However, we have some reservations about this product because it’s not backed by any clinical studies. Furthermore, we’re concerned about its lack of availability online and in stores.

If you’d like to drop more pounds of fat, then we recommend you go with a supplement that is easy to purchase online, is backed by solid scientific research and is supported by numerous user testimonials.

Among the best products we’ve seen this year is one called Leptigen. This supplement uses a combination of four key ingredients, which have been shown in documented clinical studies to help increase fat loss and kick-start metabolism. You should also know that we can’t find any discouraging user comments, and customer reviews on the web reveal people are seeing solid results.

The makers of Leptigen are so positive about their product they’re offering a Special Trial Offer, which is uncommon.

What You Should Know about Slender X

You may need a little assistance with weight loss. This is nothing to be ashamed of. Countless dieters across America and other parts of the world seek out help with weight reduction. When exercise and diet are not enough, there are dietary supplement formulas to consider. However, you need to be leery of harmful ingredients like Ephedra and Ephedrine. These can lead to serious side effects. It is always beneficial to see the actual ingredient label on a diet pill or supplement bottle before you choose to buy it. We are going to give you the rundown on Slender X tablets, which are sold online for weight loss.

Slender X Ingredients:

  • Yerba Mate
  • Green Tea Leaf Extract

Product Features

Slender X is a weight loss supplement manufactured in the UK. Therefore it is not available to Americans, or at least it is not sold for American currency. 100 tablets are sold in each bottle, and this product is taken three times each day, after each major meal. Slender X is directed to be taken for at least twelve consecutive weeks. This product may help by preventing the absorption of fat, boosting the metabolism, and suppressing hunger. However, there are no side effects mentioned for this diet pill.

Yerba Mate is one of the main ingredients used in Slender X tablets. It is claimed to assist the body by increasing metabolic rates, suppressing appetite, and mobilizing fat so it can be burned off. The only other active ingredient mentioned is Green Tea Leaf Extract. It aims to inhibit fat absorption. This way the body does not gain additional fat. Unlike many weight loss products, Slender X is not recommended for women and men with a BMI lower than 25.

Advantages of Slender X

  • Natural ingredients are used in this weight loss product.
  • Slender X is suitable for women and men trying to shed weight.

Disadvantages of Slender X

  • Slender X contains significant amounts of caffeine, which may lead to insomnia.
  • There is no money-back guarantee provided with this diet product.
  • No complete ingredient list is provided for consumer review.
  • There are more promising weight loss products out there.


There is simply not enough data provided on Slender X for us to recommend it. For instance, there is no complete ingredient list, no clinical research results, and no customer testimonials or success stories. You cannot even purchase this product if you live outside of the UK. On a side note, the key ingredients mentioned for Slender X are very common, and can be found in plenty of other diet pills online. However, some of those alternative products are sold with a money-back guarantee.
