Instant Knockout vs Hydroxycut Hardcore Elite

Another battle of the fat burners today and our Instant Knockout vs Hydroxycut Hardcore Elite Review promises to be a good one.

Here we have two of the bigger names in the supplements industry going up against each other to show us which deserves to be crowned as our winner today.

With so many fat burners out there, you would almost be forgiven for thinking that this crowded market is a difficult place to find an effective supplement. It is true that 9/10 of the supplements we come across are either ineffective or even unsafe. This makes our role even more important.

Since we review 100s of supplements, we take the pain out of searching for the best fat burner. If either of these two products is to be taken seriously they will need to do the following effectively:

  • Burn problem areas of fat
  • Increase energy
  • Suppress appetite
  • Be safe

Since both products claim to promote fat loss in efficient ways, we are going to see which can keep it’s marketing promises.

Hydroxycut Hardcore Elite alone claims to be a ‘super thermogenic’ so let’s see which has the better ingredients as we go along.

First in our Instant Knockout vs Hydroxycut comparison, let’s get to know the manufacturers a little better.

Instant Knockout vs Hydroxycut Hardcore Elite: Who Makes These Fat Burners?

Roar Ambition

The people behind Instant Knockout are this UK based supplements company.

With an excellent reputation based on the fact that they have a generous money back guarantee, and they regularly update their ingredients and dosages to ensure their customers are getting the best possible product.

This product is used by none other than UFC fighter Diego Sanchez, who uses it to make weight before a bout. Not only is it good that it is safe for competition and the pros are using it, but the fact that it is used in such a high profile sport is a good thing too.

They ship all their products from the UK and USA directly.


These guys are responsible for Hydroxycut Hardcore Elite and are one of the bigger names in the supplements industry.

They have everything from multiple fat burners (this is just one of them) to protein cookies.

They make all their products to the GMP standards and they make their products in the USA. Time to see if all this good practice so far translates into a good product.

Instant Knockout vs Hydroxycut Hardcore Elite Serving Schedule

We had to include this section for this review since the Instant Knockout suggested serving is 3-4 times daily – This is our preferred method for a fat burner since it spreads the benefits out throughout the day.

Trying to compare Instant Knockout to Hydroxycut Hardcore Elite is where it gets a little messy.

Ok, so listen up this is where it gets complex…

Hydroxycut’s suggested serving is to start by taking one capsule a day for the first two days, Then take 2 a day on days 3 and 4. Days 5 and 6 you can take once with your first meal, and two capsules with your second.

After a week you can take 2 capsules twice a day.

Still awake?

Then we will take a look at what goes into these fat burners.

Instant Knockout vs Hydroxycut Hardcore Elite Ingredients

Well, the first thing to say is that neither of these products uses proprietary blends which is always a good thing. The act that we can see and compare dosages is important to us.

Mutual Ingredients

Caffeine Anhydrous

This is the powdered form of caffeine that makes it easier to absorb into your system.

Of course, it is good for an energy boost and when you are sweating it out in the gym this will come in handy. Also, if you are on a diet that requires you to consume fewer calories than usual, this is the type of ingredient that you will be thankful for.

It is also a good metabolism enhancer so it has multiple fat burning benefits.

The 350 mg in Instant Knockout makes it a good ingredient and the 270 mg in Hydroxycut Hardcore Elite should be enough to help as well.

Green Coffee Bean

Another great inclusion from both of these products and another that has various fat burning qualities.

The chlorogenic acid from Green Coffee Bean stops your body from absorbing more fat for a start, combine this with the fact that it also encourages your body to use fat for energy, burning it off in the process and you can see why many fat burner supplements turn to this ingredient.

The 200 mg in Hydroxycut Hardcore Elite is good although the 100 mg in Instant Knockout will still do a job and not send you over the edge when it comes to stimulants.

Individual Ingredients

Instant Knockout

Cayenne Pepper

When it comes to fat burners, this is the ultimate ingredient.

We love it because not only is it a proven thermogenic, meaning it heats your body up, encouraging it to burn fat to cool itself down, but it also has other benefits.

It is a great appetite suppressant, meaning you are less likely to be reaching for the snacks in between meals.

Another ingredient that encourages your body to burn the fat it has, as well as prevents you from putting more on.


One of those ingredients that catch the eye, and for a good reason.

It is another appetite suppressant. This fiber absorbs water and swells in your stomach making you feel fuller and for longer. One of the many reasons Instant Knockout is such an effective fat burner.

Hydroxycut Hardcore Elite


It has its similarities to caffeine, only it is thought to be less potent.

It is likely to be included because it gets your heartbeat going faster, the theory there is that it will encourage your body to burn fat. Most would argue that this is better for increasing energy levels.

There is even loose research that suggests it could be an appetite suppressant, but if they were going for that with this ingredient, they would be far better off including some of the proven ingredients that are known for this.


Although this is thought to have some decent fat burning capabilities, it is not without its controversy.

Firstly, let’s just say it is thought to help your body to break down fat, making it easier to burn off and could even provide a thermogenic boost. Secondly, it is better known as a libido enhancer and is from the tree of the same name in Western Africa.

The problem, however, is the potential side effects. These are pretty serious and include elevated blood pressure and heart rate, sleep problems, headaches, sinus pain and more.

Instant Knockout vs Hydroxycut Hardcore Elite Side Effects

Well, the good news here is that because Instant Knockout use 100% natural ingredients, all at safe and optimal dosages, their product is free of known side effects.

The bad news is that Hydroxycut Hardcore Elite has included Yohimbine, making their product one we would stay away from. The potential side effects we mentioned in the previous section and can be quite serious. Anything that can elevate blood pressure and heart rate needs to be taken seriously.

Alarmingly, these are even more likely when taken alongside stimulants, and this product is full of them.

The final nail in the coffin is the fact that it is recommended that you consult your doctor before taking any of this ingredient.

This wasn’t really close in the end, there was only one product that delivered on its promises and even delivered on some the promises that Hydroxycut Hardcore Elite promoted but couldn’t live up to.

There are just so many effective ingredients that are optimally dosed in Instant Knockout. The fact that they include multiple thermogenic ingredients, whilst Hydroxycut Hardcore Elite didn’t use any proven thermogenics made it even easier to crown them as the winner today.

On top of this Instant Knockout included two of the best appetite suppressants that we like to see in a fat burner in Cayenne Pepper and Goucommaman.

Instant Knockout is also a completely safe fat burner, something that cannot go unnoticed in this industry. You see how easy it is for a decent supplement to become one you shouldn’t use when you look at the inclusion of Yohimbine in Hydroxycut Hardcore Elite.

All in all, if you want to take a closer look at one of the best fat burners we have seen, check out our full Instant Knockout review.
