LeanBean vs Stacker 2 Fat Burner

An interesting comparison today. With two different approaches which of our LeanBean vs Stacker 2 Fat Burner Comparison will give us a fat burner suitable for a female user?

Their reputations have brought their products to our attention and we are looking forward to seeing which is the better option.

In order to impress, they need to do the following well:

  • Burn fat effectively
  • Be safe
  • Suppress appetite
  • Increase energy

Only the best ingredients and effective dosages are going to ensure they work. Let’s start by getting to know the companies a little first.

LeanBean vs Stacker 2 Fat Burner: Who Makes These Products?

Ultimate LifeLeanbean Fat Burner

We are starting with the UK based company that makes LeanBean today.

They have a great reputation online with a lot of people taking to the net to post their before and after profiles.

The use FDA approved facilities and even give you a big 90 – day money back guarantee so you can try it on for size properly.

This is also an option for any vegetarians looking for a fat burner. It is endorsed by ex-pro surfer and model Bree Kleintop. She is just one more person who has a lot of good to say about it as many others seem to.

It has been created to suit the female body so hopefully the ingredients and dosages will reflect this.

NVE PharmaceuticalsStacker 2 Fat Burner

Now for the US-based company that makes Stacker 2.

They make some big claims, in fact, they say they make the world’s strongest fat burner. The Stacker 2 brand has been going since 1997.

Another of their selling points seems to be that this is ephedra free. This is good as Ephedra is a banned substance because of potential side effects. The fact that they used to include this isn’t great but they don’t any longer.

Some of the places you might have seen their products include the UFC, NBC, Fox News, and other TV channels/programmes.

With free shipping for orders over $50 but no money guarantee, it is a mixed bag of things we do and don’t like to see.

They sell well on Amazon but this doesn’t always result in a good product as we have seen via other reviews.

Still, it has a chance to shine here today so let’s see if it is any good for a female user.

LeanBean vs Stacker 2 Fat Burner Ingredients

This is where we can really separate the two.

The early signs aren’t the best for Stacker 2 though. They include all but one ingredient in a proprietary blend. This means we don’t get to see all the dosages.

Mutual Ingredients

Green Tea Extract

A great start by both, this is up there with the best fat burner ingredients.

For fat burning, it acts as a thermogenic. This means it heats the body up on the inside, causing it to burn fat to cool itself again.

WebMD says that Green Tea contains a milder caffeine content than the likes of Caffeine Anhydrous. They say it is actually around 2-4% Caffeine. The boosted focus is a nice bonus.

It is the polyphenols in Green Tea that are so good because they reduce the impact of oxidative stress and leave a calming effect.

The dosage in LeanBean is an excellent 200 mg. We have no idea how much Stacker 2 has provided because of the proprietary blend.

Individual Ingredients


Raspberry Ketones

Unfortunately, this isn’t the most reliable ingredient.

It was once thought to be the next big thing in the fat burning world. Since then though, it doesn’t have a lot of backing.

WebMD tells us that Raspberry Ketones can affect the hormone adiponectin. This would be of use here as it is believed to be capable of reducing appetite and increasing the rate that we burn fat.

WebMD goes on to say that there is no reliable scientific evidence that raspberry ketones improve weight loss when taken by people.

The 8 mg included isn’t taking up a lot of room and they are clearly backing other ingredients anyway.


A welcomed return to the proven ingredients.

This is a dietary fiber that swells in the stomach, absorbing water. This makes the user feel fuller for longer as is what you want from a fat burner.

A reliable ingredient that gets a great dosage of 500 mg.

Vitamin B6

It works in a similar way to other B-vitamins in that it helps to convert food into energy.

This makes it a very useful ingredient and it can even enhance muscle performance. The 3.72 mg included is a useful amount.


An ingredient that can improve insulin resistance and even help to regulate blood sugar levels.

WebMD also advise that Chromium can decrease LDL (bad cholesterol) levels in those who have lower blood fat levels.

Vitamin B12

Another B-vitamin and one that stops us from absorbing as much fat.

Less fat on the body means less to burn off and since it cannot be created naturally, supplementing it is a good idea.

Acai Berry

High in fiber, this Brazilian health food has a lot to offer.

By boosting metabolism it helps us to process food a lot faster. LeanBean are big believers and the 800 mg included reflects this. A big amount that is about the same dosage as all ingredients in Stacker 2’s proprietary blend combined.

Green Coffee Bean

Another excellent fat burner.

Basically, this is coffee before the color and chlorogenic acid has been roasted out.

It is this acid that is great for preventing us from storing as much fat. It also keeps blood sugar levels under control.

WebMD tells us about one study that looked at adults with obesity. This showed that taking Green Coffee Extract for between 8 to 12 weeks resulted in more weight loss for those when compared to others taking a placebo.

The dosage is huge. 6,000 mg of an effective and well-tolerated ingredient will really be of benefit here.


A really clever ingredient to include in a female fat burner.

It is an ingredient that works in a similar way to Caffeine but isn’t a stimulant, meaning this product is free of them.

Turmeric boosts metabolism and warms the body so you get all this without the risk of an energy crash. The dosage of 200 mg is also a great amount.

Garcinia Cambogia

Another great addition.

It is an appetite suppressant and the skin is what is the most beneficial. High in hydroxycitric acid, it increases fat oxidation during exercise.

There is a study that showed how it helped slightly in terms of fat loss in comparison to a placebo group after 16 weeks.

The 400 mg dosage is another optimal one.

Cayenne Powder

Another thermogenic, there is a reason it is such a popular fat burner ingredient.

Also, it is an appetite suppressant. Cayenne Pepper has also been shown to curve appetite and this is, even more, the case for those who do not already eat spicy food (WebMD).

At 60 mg you are getting a good dosage for a female fat burner.

Black Pepper Extract

The final ingredient in LeanBean and a good one.

It might not be a direct fat burner but it enhances the capabilities of the other ingredients. This is good because it is a product that is full of them.

The 20 mg dosage is also one that will work.

Stacker 2

Yerba Mate

Because of the Caffeine content, it certainly has a role to play.

Another thermogenic, it is good to see both products getting enough of them in.

It is also another that suppresses appetite. Examine.com says it has not been shown to be a more effective fat burner than compounds like Green Tea Catechins, though it can help reverse some of the adverse health effects associated with obesity.

So, not as potent in terms of its effectiveness but also, the added Caffeine is something we could probably do without.

Since we don’t know the dosage it is hard to say how effective it can be as well.

Guggulsterone Gum Extract

A disappointing ingredient really.

Examine.com says it has been investigated for their usage in elevating thyroid function, but with lackluster results.

It’s not just them, WebMD are not impressed either. They advise that Guggulsterone Gum Extract is commonly used for weight loss in people who are obese or overweight. But there is limited scientific research to support these uses.

The lack of dosage information is once again a pain.

Cassia Nomame Plant Extract

A better ingredient although not common.

WebMD advise that people take it by mouth for weight loss. It is thought to work by preventing the body from absorbing dietary fat. It causes this fat to be excreted in the feces, which might help promote weight loss in some people.

They do continue though and say there is insufficient evidence in terms of weight loss.

Also, as it is understudied, the dosage needed it not really known.

White Willow Bark Extract

Another uninspiring ingredient really.

It can enhance the capabilities of the other ingredients but since these aren’t great, it isn’t the best.

It is thought that White Willow Bark Extract actually works in a similar way to Aspirin because it can alleviate pain but this isn’t really what we are after.

Some people have noted some side effects from using it though. WebMD says these can include the likes of itching, rash, and allergic reactions, as well as an upset stomach. WebMD also says that it is likely to be safe, but not when taken for longer periods.

The proprietary blend prevents us from knowing if it can be effective anyway.


A proven fat burner that is a very common one.

It works by increasing metabolism as well as giving you an energy boost. This is good for the gym but also if you are on a diet that restricts calories.

A mainstay in various supplements including pre workouts and nootropics.

The problem here is the dosage. At 200 mg per capsule, it would be a good amount if you only consumed one or two. Taking a third gives you a big 600 mg which will not be so well tolerated by everyone. Even the FDA advises that this is too much.

Would you drink 6 cups of Coffee?

Potential side effects from too much Caffeine includes insomnia, jitters, anxiety, high blood pressure, irritability, upset stomach and more.

LeanBean vs Stacker 2 Fat Burner Side Effects

Let’s just start with LeanBean because their mix of natural ingredients and safe and effective dosages, there is no risk of side effects.

The level of stimulants in Stacker 2 is a bit of a concern.

The 600 mg of Caffeine could be problematic for some people and the side effects of such a dosage include insomnia, jitters, anxiety, high blood pressure, irritability, upset stomach and more.
