Protein World Fat Metaboliser Capsules or Leanbean? We’re here to tell you which is the best out of these two popular supplements.

Both of these products are widely used but often it can be hard to know which is the most effective without spending endless hours on research.

Fortunately for you, we’ve analysed both of these products in order to help you make the best decision when it comes to picking one.

In this comparison article, we’ve taken a good look at both Protein World’s Fat Metaboliser Capsules (previously known as Fat Melter capsules) and Leanbean, focusing on the following five categories:

Company reputation and product background
• The servings
• The ingredients and dosages
• Side effects
• Price

Then, we’re going to choose which one of these two supplements we like the most.

So, let’s get on with it and start comparing Protein World’s Fat Metaboliser Capsules with Leanbean.

1) Company reputation and product background

Both Protein World Fat Metaboliser Capsules and Leanbean are well-known products, so you may already know some of the main benefits of them.

But here is a short summary of each product to get us started:

Protein World Fat Metaboliser summary:

• Made by Protein World
• Designed to support your goals
• Includes high caffeine content
• Large social media presence

Leanbean summary:

• Is only available directly from the manufacturer
• Has a low level of stimulants
• Vegetarian and natural supplement
• Marketed at women
• Contains 12 ingredients

As you can probably tell, we think that Leanbean is a more comprehensive product when compared to Protein World.

The main reason we prefer Leanbean is because it is designed to work in a number of different ways.

It was also a decisive factor that Leanbean was initially used by professional fitness models and athletes.

Leanbean wins round one

Leanbean: 1 | Protein World: 0

2) The servings

If you’re finding it difficult to choose a supplement of this type then a good place to start is often the label.

You’ll want to make sure you choose a supplement that has constant support for your goals.

By giving your body the ingredients at regular intervals you’ll prime yourself for success.

Each bottle of Leanbean contains 120 capsules, this is enough for four a day over the course of a month.

With Leanbean, you take one capsule four times a day with food.

Each bottle of Protein World’s Fat Metaboliser contains 90 capsules.

With Protein World, they recommend that you only take two capsules a day.

As a result we’re going to have to score round two to Leanbean as well. That’s because when it comes to this kind of product we like supplements that work all day long.

The fact that you get to take Leanbean more often throughout the day means that it’s very likely to be more effective.

Leanbean wins round two

Leanbean: 2 | Protein World: 0

3) The ingredients and dosages

Next up is arguably the most important factor – it’s the ingredient list.

We’re profiled both products to see if the substances in them deliver the results you’re after.

Let’s get down to it and compare the ingredient list of both of these supplements:

protein world leanbean

As you can clearly see, these supplements are quite different when it comes down to their ingredients.

One advantage to both products is that neither hides their ingredient doses in a proprietary blend, this means we can see exactly what’s in each product.

Here’s a break-down of our favourite ingredients in both products:

Leanbean’s top ingredients:

• Turmeric
• Green Tea Extract
• Cayenne Powder
• Green Coffee Bean Extract
• Glucomannan
• Chromium
• Black Pepper Extract

Protein World Fat Metaboliser’s top ingredients:

• Caffeine Anhydrous
• Green Tea Extract
• Cayenne Pepper
• Choline

As you can see from the comparison above, Leanbean contains far more of our favourite ingredients.

Indeed, it was a shame not to find more of our top compounds in Protein World.

For example, Protein World doesn’t contain Turmeric, Green Coffee Bean or Glucomannan. These are some of the most effective ingredients out there, and so it was a bit of a surprise not to see them in Protein World’s formula.

Leanbean contains a solid amount of all three of those ingredients as well as added extras such as Black Pepper and Chromium.

A lot of Protein World’s appeal seems to be based on celebrities and social media, however when it comes down to the ingredients we did find that the product fell somewhat short.

This round goes to Leanbean because of its better ingredient profile.

Leanbean wins round three

Leanbean: 3 | Protein World: 0

4) Side effects

The next thing to consider on our comparison list is safety.

We want to know that any supplement we use is safe and that it doesn’t contain any questionable ingredients.

Thankfully, these kinds of sports supplements tend to be safe because they use mostly plant extracts and other similar ingredients.

The key thing to consider comparing this kind of supplement is that they can often use a lot of stimulants.

Leanbean only has caffeine from natural sources like Green Tea and Green Coffee Extract.

Protein World Fat Metaboliser contains 200 mg of Caffeine per daily serving – we think this is on the limit for a fat burner aimed at women.

In any case, we never recommend taking these kind of supplements too close to bedtime as the Caffeine content can potentially disturb your sleep.

The fact that Protein World Fat Metaboliser also includes Guarana Extract, another ingredient that’s high Caffeine means that it could possibly be too much for some people.

This round also goes to Leanbean because of the slightly lower stimulant content.

Leanbean wins round four

Leanbean: 4 | Protein World: 0

5) Price

The final category in this comparison article is price. Which is the cheapest?

The price of Leanbean is £35 / €45 / $59 per bottle and you can only buy it from the official website.

Protein World’s Fat Metaboliser is currently priced at £22 / €34 / $38 per bottle and you can find it on the official website or via some other online retailers.

It’s worth remembering the fact that Leanbean does include significantly more capsules per bottle.

However, all things considered, Protein World Fat Metaboliser is still the cheaper product of the two.

The only way Leanbean can compete in terms of price is through the multi-box deal on its official website. This promotion is called their Bikini Body Bundle and means when you buy three bottles you get a fourth bottle for no extra charge, you also get a free workout guide included in this.

However, this round clearly goes to Protein World Fat Metaboliser.

Protein World wins round five

Leanbean: 4 | Protein World: 1
