Instant Knockout vs Redburn Hardcore Review

Here we have one of the best fat burner supplements in the industry vs a relatively unknown newcomer. This promises to provide an interesting battle – Instant Knockout vs Redburn Hardcore. A true international battle on our hands here as its UK vs France!

Time to get serious then, each of these comes with their own reputation and have grown significantly over the years. This is all very well, but whilst other people are saying good things about them, it is our turn to put them to the sword.

We will be finding the answers to questions like, what ingredients does Instant Knockout have? And, how safe is Redburn Hardcore?

For a good fat burner to work, it should do as many of the following things as possible in order to gain our respect:

  • Burn Fat
  • Suppress Appetite
  • Increase Focus
  • Enhance Metabolism
  • No side effects

Sure a product is only as good as it’s ingredient, but on top of that its ingredients will only work if the dosages are right.

Let’s get to know them a little better then.

Instant Knockout vs Redburn Hardcore: Who Makes These Products?

Roar Ambition

Instant Knockout is produced in the UK by Roar Ambition, a company with an excellent reputation. Not only do they produce some of the best products around. But their commitment to quality is second to none.

They review and amend their supplements every few months. So you are getting the most improved and up to date version that is in line with the latest studies. An incredible feat!

They also have a money back guarantee and are easy to get hold of. Their commitment to their ingredients seems to be reflected in their commitment to their customers. All of their products are 100% natural so it is obvious that they are building a brand that inspires trust.

Superset Nutrition

The people behind Redburn Hardcore are Superset Nutrition and whilst we write this it seems as though their site is down, not great and definitely doesn’t inspire trust. You might wonder how legit they are, but there is enough information on ecommerce stores to show they do exist!

Don’t confuse them with a store in Florida of the same name!

What we did discover when we searched high and low for information is that their mission statement seems to be Efficiency, Quality, Security’’. They also say that their products are rigorously selected and dosed.

After we were unable to find much information, this is a reassuring claim. But we never take what a company says for the truth until we have had a look for ourselves.

Instant Knockout vs Redburn Hardcore Ingredients

This is where it gets interesting, any fat burner worth purchasing needs to step up at this point. No useless ingredients and no underdosed ones either please.

The first thing we should note is that neither use proprietary blends. This is a major plus point for us, we don’t like to see a company hide their dosages and even some of the ingredients by combining multiple ingredients into one blend.

We much prefer to see how much of every ingredient is in each serving. That way we can make a much more informed decision when purchasing. It also makes reviewing a lot easier, how are you supposed to tell if an ingredient is effective if you don’t know how much of it is in the product?

Mutual Ingredients

Green Tea Extract

Anyone who drinks this instead of a coffee in the evening is onto something. A proven thermogenic and an excellent inclusion in a fat burner. It heats your body up in side making it burn fat to cool itself down. An ingenious method for burning fat, make your body do the work!

It is one of those ingredients that should be in any fat burner and Reburn Hardcore have made it the focal point of their supplement by including 1,000 mg of it whilst Instant Knockout contains 500 mg. Both are effective dosages and will be enough to do what you want it to, but we will give this one to Redburn Hardcore.

Cayenne Pepper Extract

Another excellent inclusion from both of these supplements and a great way for anyone who isn’t a fan of spice to get the benefits of this ingredient without having to consume it through food.

Its use in a pre workout is mainly to increase your metabolism through thermogenesis again, however it is also a decent appetite suppressant. Anyone who can’t resist a snack in between meals might need a bit more of this in their diet.

Redburn Hardcore have included a decent amount in 200 mg, and although Instant Knockout only has 100 mg, it will also be effective.

Unique Ingredients

So it’s been a close one so far, and although Reburn Hardcore has the edge, it is only two ingredients and it might be the case that they were both of Redburn’s major ingredients. However, let’s continue with…

Instant Knockout


The glucomannan found in Instant Knockout is taken directly from the konjac plant which has a great deal of dietary fiber in it. Another excellent appetite suppressor it will help you to reduce your calorie intake throughout the day.

It swells inside your stomach and helps with your appetite by absorbing liquid. Therefore it rids your body of excess water and also stops your body from pining for food. The huge dosage of 1,800 mg is great.

Caffeine Anhydrous

Another great ingredient, not only will it boost your metabolism but it will also increase your energy and burn fat to do so. If you use this before exercise it will also boost your output levels.

You need more energy when taking fat burners, especially if you are on a calorie reducing diet.

This is a high concentration of caffeine and a quality ingredient. Oh and did we mention it also increases the effectiveness of various other ingredients in this fat burner such as Green Tea Extract and Cayenne Pepper. 350 mg is a safe and optimal dosage.

Vitamin B6

Another ingredient down and another metabolism booster. The B6 included in Instant Knockout is pyridoxine. Which not only turns food into much needed energy but encourages your body to absorb protein, great for muscle growth and recovery.

Redburn Hardcore

Ceylon Cinnamon Extract

Although there is some evidence to suggest this ingredient has an effect on controlling insulin spikes (good for post carb heavy meals), there is also evidence to show that Cinnamon can be toxic if taken in too high a quantity.

It’s an interesting inclusion for sure, but the toxicity is a concern as too much Cinnamon in your everyday diet can result in high levels of coumarin, the liver toxin in your body.

White Willow Bark Extract

Got a headache? Then find a White Willow Tree and grab some bark to chew, it’s a proven headache antidote. But what is it doing in a fat burner? Well, we’re not actually sure to be honest. There isn’t any concrete evidence to show it is a proven fat burner so we’re not a fan.

If you are on any blood thinning medication then consult your doctor before you consume this ingredient in any form as it can have negative effects.

Instant Knockout vs Redburn Hardcore Side Effects

We are pleased to say that there aren’t any major side effects from either product here. Instant Knockout is completely natural so this doesn’t surprise us.

Although there is a minor concern over the cinnamon content in Redburn Hardcore. We don’t think it is anything major to worry about unless you consume large doses as part of your regular diet.

(Clean Lean Machine tip: Get 1 box free when you buy 3 boxes!)

Redburn Hardcore started well with decent dosages of both Green Tea Extract and Cayenne Pepper. But in the end it needed more than that as Instant Knockout proved to have many fat burning ingredients instead of relying on just two.

Redburn Hardcore let itself down by having a lot of filler ingredients. Also the fact that it was so hard to find information on it made it a little frustrating.

Instant Knockout contained a variety of useful fat burners from appetite suppressants to energy increasing caffeine. The overall quality of this fat burner is hard to beat, in fact we haven’t found anyone that has!
