Instant Knockout vs Nite-Burn Review

The best of the daytime fat burners (is that even a thing!?) against a night time product. Yes, our Instant Knockout vs Nite-Burn reviews have a bit of an interesting twist today.

Instant Knockout, regarded by many as the best fat burner going goes up against a novel idea from BPI Sports, Nite-Burn. This is a fat burner you take just before bed.

Is this a better idea than an effective fat burner that burns fat all day long?

Or is it just another attempt to be different and stand out that falls flat on its face?

So, which is the dream supplement and which is the stuff of nightmares?

We will be treating these the same as other fat burners and focusing on ingredients and dosages. Both will need to show us that they are the best option for burning fat effectively.

Time to see which of these is the best option for you.

Instant Knockout vs BPI Nite Burn: Who Makes These Fat Burners?

Roar Ambition

The people behind Instant Knockout are UK based Roar Ambition.

With one of the best reputations going, these guys ship from both the UK and USA directly.

They have loads of people willing to add their testimonials online and plenty of before and after profiles are easily found.

Part of their reputation is based on the fact that they review their ingredients and dosages regularly. This means the customer is getting the best possible version at all times They also have a generous money back guarantee – 90 days in fact!

This is massive and gives the customer the chance to really see the difference. Not enough companies have this and the usual amount is just 30 days.

They also have some impressive endorsements. UFC fighter Diego Sanchez puts his name to this fat burner and he uses it to make weight before a bout.

BPI Sports

Here we have one of the industry’s bigger names.

Their website is slick and easy to get around and you can see from the range of supplements they offer that they have a good market share.

With everything from protein-related supplements to pre-workouts, they have a lot of bases covered.

They have a 30 day free returns policy. It is good that they have this as some companies don’t offer anything here. Our problem is that it can take a fair bit longer for you to feel the difference when it comes to supplements. Everyone is different though!

They have their Trustpilot score on their site which is pretty average at 3 out of 5. We commend them for featuring this anyway.

Instant Knockout vs Nite-Burn Ingredients

Now we can see which is going to be the most effective.

The problem we have from the start is the proprietary blend in Nite-Burn.

Thankfully Instant Knockout does not do this and is honest and open with their ingredients and dosages.

A proprietary blend is where a company will bunch a lot of ingredients together and only give the overall dosage. This means we cannot see how effective each ingredient is in Nite-Burn.

The blend here is particularly prominent with only one ingredient not featuring.

The suggested serving is not ideal either from BPI Nite Burn. Of course, they can’t recommend you waking up in the night to take a second, third or forth serving but taking just one capsule before bed doesn’t seem potent enough for a lot of fat burning.

Instant Knockout has got it right by suggesting taking 3-4 times a day, ensuring the fat burning benefits can be felt throughout the day.

Now for the ingredients.

The only mutual ingredient here is Green Coffee Extract which through its chlorogenic acid encourages your body to use fat instead of food for fuel, burning it off in the process.

A good ingredient and since we know Instant Knockout includes 100 mg we give them the edge over the proprietary blend!

Time to look at the most interesting ingredients from both.

Instant Knockout

Green Tea Extract

One of the best fat burning ingredients going.

We like this because it works on a few levels. Firstly it is a great metabolism booster, just what we are looking for really.

It doesn’t stop there. This ingredient also helps you to get the most in terms of fat burning out of the exercise. When taken alongside a workout routine it is a perfect pairing.

The 500 mg in Instant Knockout displays their knowledge of what a good fat burner should look like.

Cayenne Powder

Another great inclusion.

This time it is because this works on two different levels.

A great thermogenic, by this we mean it heats up your body on the inside, causing it to burn fat to cool itself down. It doesn’t stop there though. It is also an effective appetite suppressant.

It swells in the stomach which makes you feel full, the kind of trait a good fat burner should have.

At 100 mg there is enough to do what you would want it to.


Another great appetite suppressant.

This version is derived from the Konjac root and is a dietary fiber that swells in your stomach once more, absorbing water and making you feel full and less likely to reach for a snack.

The 500 mg once again proving their commitment to helping you to lose fat.

Caffeine Anhydrous

Where will you get your energy from when taking a fat burner on a lower than usual calorie diet? Or if you are using it alongside your workout routine?

Caffeine is a staple ingredient in any fat burner, in most cases anyway.

The benefits go beyond an energy boost. The fact that it is also an effective metabolism enhancer means you will be burning fat even when you are resting.

At 350 mg it is a sensible but effective dosage from Instant Knockout.

BPI Nite Burn

Vitamin D3

The only ingredient not in the proprietary blend so let’s see if the 1,200 IU included here is worth it.

You will usually find this ingredient in a T booster and since there are so many people deficient in D3, it is a decent idea here.

In terms of fat burning there are studies to back up its ability but some of this depends on body weight. There are links to lower rates of D3 in those with higher body fat, but this could be because of diet.

Raspberry Ketones

This was once considered a potentially good fat burner ingredient and was pretty much the word on everybody’s tongues once upon a time.

This has since been disproven with most people now considering the results of the lab tests on rats that created the hype have not even yet been trialled with humans.

A disappointing inclusion really and we also have no idea how much there is since it is part of the proprietary blend.


Really this is here because it is a diuretic.

The idea is that by causing you to urinate more frequently, you will lose the water retention. The problem is, it is part of a nighttime supplement. For it to work you will need to be up in the night to go to the toilet!

Not a great inclusion.


Included to help you get a peaceful nights rest as this is a relaxant often used in sleep-related supplements.

A good idea for the intended use of this supplement, but it still doesn’t help you to burn fat.

Instant Knockout vs Nite-Burn Side Effects

There isn’t anything in either product that concerns us in terms of side effects.

Usually, the proprietary blend would be a concern but since BPI  Sport Nite-Burn does not include stimulants or anything to worry about, it all seems safe.

Well, our Instant Knockout vs Nite-Burn review turned out to be a nightmare for Nite-Burn as Instant Knockout showed how hard it is to beat.

A top fat burner like Instant Knockout does everything right so it was going to take something special to beat it.

Unfortunately, the proprietary blend and lack of effective fat burners from BPI Sport meant this was a one-sided contest.

Without stimulants, they miss out on half of the benefits. Also, there is little need for appetite suppressants in a nighttime fat burner – one of the other key traits for this kind of supplement.

These are part of the reason Instant Knockout is so effective, it has all of these in abundance. On top of this, the serving suggestion means your body will be burning fat all day long.
