Xtreme Slim is a fat burner supplement made by Prime Labs which promises to help you burn more fat and get into shape quicker.

We’re always looking to find out more about the latest fat burner supplements to hit the market, so naturally we wanted to know a bit more about Xtreme Slim.

We all know that burning fat is not an easy affair, and so picking a quality fat burner supplement to support your efforts is always a good idea.

Prime Labs are one of the biggest names in the supplements industry and we’ve already taken a look at some of their other product such as Prime Test.

Xtreme Slim is available to buy on Amazon and some other popular outlets such as GNC, and it seems to be relatively well-received amongst consumers.

The purpose of this Xtreme Slim review is for us to take a close look at this fat loss supplement from all angles as we look to try and determine exactly where it stands in comparison to the leading products on sale right now.

We've picked out the top five leading fat burning supplements on the market right now.

We’re going to focus on all of the important aspects, from the ingredients, to the doses and customer reviews, as we look to determine exactly where this product ranks.

Xtreme Slim – The Basics

As we’ve already deduced, Xtreme Slim is a fat burner supplement made by Prime Labs which is available to buy at various online outlets including Amazon.

It claims to use an “advanced” formula to help get your body burning more fat naturally.

The marketing material says that it is “jam-packed” with natural ingredients to help get your body burning more fat and help you to reach your weight loss goals.

The official listing on Amazon says that this product will help to:

• Boost Energy Levels
• Suppress Appetite
• Increase Thermogenic Fat Burning

It’s great to see that Prime Labs have formulated this product to work in multiple ways. Generally speaking, the best fat burner supplements on the market work in at least two ways.

Put simply, a multi-action fat burner is going to be more effective than a supplement which works in just one way.

The Amazon listing says that Xtreme Slim is the supplement to help you to reach your “ideal body weight”.

Of course, we’ve heard it all before when it comes to the marketing hype surrounding fat loss supplements, so it’s always best to take a look at the ingredients to see whether a product is actually going to be effective or not.

So with that in mind, let’s now start to take a look at the Xtreme Slim ingredients formula in detail to see exactly where this product ranks in comparison to the competition out there at the moment.

The Ingredients

Let’s begin this part by having a look at the actual ingredients label of Xtreme Slim in full.

The Xtreme Slim ingredients formula in full. This product doesn't use a proprietary blend
The Xtreme Slim ingredients formula in full. This product doesn’t use a proprietary blend

The first good thing we immediately noticed about the ingredients formula is that it doesn’t use a proprietary blend, which is always good news.

We always advise that you steer clear of products that use proprietary blends, because it means that you don’t know the doses of the ingredients used, which makes it difficult to judge effectiveness.

The interesting point about Xtreme Slim is that it uses exactly the same dose of 130mg per ingredient in its formula. We’re not too sure about this, because different ingredients need different doses in order to be effective.

Anyway, let’s now take a look at the actual ingredients that Xtreme Slim does contain.

• Green Coffee Bean – This is a solid place to start for any fat burner supplement. Green Coffee Bean is among the best fat burning ingredients because it’s rich in a substance called Chlorogenic Acid, which can help with fat loss. The only problem here is that the dose is a bit small. Most of the top fat burners usually use at least 1000mg to be effective.

• Raspberry Ketones – Another decent ingredient. This an extract taken from the skin of raspberries which is thought to work by helping to control hunger hormones. Raspberry Ketones is one of the main ingredients in Leanbean, which is currently our top rated female fat burner supplement.

• Garcinia Cambogia – Again, this is another ingredient included in some of the top female fat burner supplements. It works by influencing the levels of hunger hormones to help make sticking to your diet easier and potentially boost your fat loss results.

• Caffeine Anhydrous – A good ingredient for any fat burner. Caffeine is a powerful stimulant which will help to raise and maintain your energy levels to keep you feeling on point, even if you’re cutting back on the calories. The 130mg dose is a sensible amount, as it will help to keep your energy levels up but not bring about any side effects such as the jitters or energy crashes.

• Green Tea Extract – One of the best fat burning ingredients you’re going to come across. Green Tea, as well as being full of antioxidants, is a natural thermogenic ingredient which will get your body burning more fat by stimulating your metabolism. We always recommend that you look for Green Tea as a fat burner ingredient when choosing a product for yourself.

What’s Missing?

The Xtreme Slim formula contains a few decent ingredients, it’s certainly also missing some of the best fat burning substances out there.

Here are the main things we were disappointed not to find in this supplement:

• Cayenne Pepper
• Glucomannan
• Black Pepper Extract

Cayenne Pepper is one of the best natural thermogenic ingredients around. We always recommend checking that your fat burner supplement contains some Cayenne Pepper, as it’s a potent metabolism booster which also doubles up as an appetite suppressant. It’s a real shame that there was no Cayenne Pepper in Xtreme Slim.

Glucomannan, meanwhile, is one of the best appetite suppressing ingredients around. It’s a dietary fiber taken from the root of the Konjac Plant, which swells in your stomach and can help to keep you feeling fuller for longer.

And Black Pepper Extract (which is also sometimes known as Piperine) is a great addition for any supplement because it’s been shown to help boost the absorption of the other ingredients. This is good, because it makes for a more effective product overall.

Xtreme Slim Reviews

We did some digging online to uncover some Xtreme Slim reviews. At the time of writing, it had 29 reviews on Amazon with an average rating of 4.8 out of 5 stars. That’s pretty good going, but we’d prefer to see more reviews on the site before drawing any conclusions.

One person said that they loved the product because it helped them to lose more weight pretty quickly.

Someone else reported that they had bought the product to help their sister lose weight and that they were glad to see that it worked.

There weren’t really any negative reviews on the Amazon listing, which we must say was a bit suspicious as most products tend to have at least some unhappy customers.

What About Side Effects?

The Xtreme Slim ingredients formula is a pretty safe one, so you shouldn’t have to worry too much about any nasty side effects.

The main problem with many fat burners is that they are often packed full of stimulants such as Caffeine. However, the sensible 130mg dose in Xtreme Slim shouldn’t cause any trouble for most people.

We do always recommend that you do some of your own research and look through the ingredients label yourself before trying any new supplement for the first time.

Is This The Best Fat Burner For Me?

Not in our opinion. Xtreme Slim certainly does contain a few decent ingredients and it’s great that Prime Labs haven’t used a proprietary blend.

However, some of the ingredients are under-dosed and this supplement is also missing some key fat burning substances such as Cayenne Pepper and Glucomannan.

Anything Else To Consider?

A good fat burner can offer a helping hand in getting you into shape, but you should never rely on a supplement to do all of the hard work for you.

The first things you should always do when picking a fat burner supplement is make sure that your diet and training regime are both on point.

There is no substitute for hard work and dedication, and a good quality supplement should only be used in conjunction with a healthy lifestyle.

Review Conclusion – Final Thoughts

So, here we are at the end of our Xtreme Slim review.

Overall, we think that this is an OK fat burner supplement that contains a fair few good quality ingredients.

However, we don’t rate it as one of the very best fat burners out there right now because it’s missing some key things such as Cayenne Pepper and Glucomannan, and some of the ingredients are also under-dosed.
