Instant Knockout Review: Ingredients, Side Effects & Customer Reviews

Instant Knockout review

Welcome to the most comprehensive Instant Knockout review…

My close buddy recently gave me a reason for the massive jealousy and inferiority complex.

He had just gotten himself the most enviable six-packs that I could ever imagine.

I remember staring agape at him, at a complete loss for words.

How, I mean, how!?

Even a few months back, he was just another normal guy in the neighborhood, cribbing about how tough it was to lose the chubby fat.

He would seem frustrated at times and I found myself in the very same boat.

We both tried to cut down our calorie count and waited it out, thinking the extra fat would just melt away like magic.

Of course, nothing of the sort happened and I kind of gave up.

I had no idea he was pursuing it in right earnest though.

Seeing him a few months down the line in a completely transformed avatar was a stunning revelation.

Now, I wanted this too.

I badgered him to share his secret until he told me about discovering Instant Knockout and how it had set him up on this journey of epic fat loss and retention of muscle mass.

But what about chemicals, I wanted to know!

He went on to talk about Instant Knockout in great detail.

I added to this information with my own research and finally embarked on this journey with great hopes of a turnaround.

And what a journey of success it has been for me!

In this Instant Knockout review, I’m going to share with you all that I discovered and went through on my Instant Knockout journey.

Instant Knockout: Is This Fat Burner Worth It?

Instant Knockout Fat Burner

What is Instant Knockout?

Instant Knockout is a fat-cutting supplement designed to help users effectively shred fat.

It is made of natural ingredients that work by boosting the metabolism, leading to efficient utilization of energy and increased oxidation of fat.

It helps synthesize energy by burning fat stored in the body and helps to cut down fat while building better lean muscle.

Who created it?

Instant Knockout has been created by a company called Roar Ambition.

It is known to produce quality health and weight loss supplements catering to users of different categories and requirements.

For anyone interested in building a well-chiseled and defined body with muscle definition, they have all-natural supplements to cater to those needs.

They are registered in Riverside Way, Leeds, England.

Why was the fat burner created?

Roar Ambition created Instant Knockout fat burner originally to help professional MMA fighters and boxers cut fat effectively and increase calorie burn.

This is because the sport demands perfect body contour and muscle mass definition to be within the competition.

The need to shed all unnecessary fat within a stipulated time period is of the essence to these MMA fighters.

Instant Knockout catered to this need naturally without using harmful chemicals or steroids.

The effectiveness and speed of action of this bodyweight loss supplement soon caught the attention of amateur bodybuilders and those seeking fitness.

Instant Knockout Ingredients

The makers of Instant Knockout have based their product on science.

They have put in extensive research and understanding of the human body and its workings to arrive at a formula.

This research has been directed at the ‘why’ and ‘how’ of fat storage in the body.

A thorough and scientific approach towards this has led the makers of Instant Knockout to select ingredients sourced from nature to counter and prevent fat storage.

Choosing each ingredient in optimum quantity to be able to deliver that ‘knockout punch’ to burn fat is the crux of the success of Instant Knockout fat burner.

Read on as I discuss in detail the constituent Instant Knockout ingredients and how they benefit the user:

1) Green Tea Extract

Green tea extract

This is one of the prime drivers in the fat burn campaign of Instant Knockout.

There is a good reason behind including this.

  • Green tea extract contains catechins which are a kind of bioactive polyphenols. These provide the power punch that helps to get through tough workouts.
  • Green tea extract helps attack and destroy stubborn fat cells using nutrients that are contained in them thus enhancing the fat loss process.
  • It boosts your metabolism to lose body fat more effectively. Green tea extract also helps bring increased energy levels in your day-to-day activities, thus engaging in continuous fat burn and helping you in losing weight in the process.

2) Cayenne Pepper Seeds

Cayenne pepper

This ingredient brings the goodness and punch of spice into Instant Knockout.

  •  Cayenne Pepper is vitamin-rich in composition, containing vitamins A, B6, and C. It delivers a big vitamin load to balance the body’s requirements in the form of pills.
  • Capsaicin is one of the driving ingredients in cayenne pepper, which is known for its fat-busting properties. This bioactive alkaloid also helps improve insulin sensitivity in the body. This translates to optimum carbohydrate utilization and better fat burn.
  • Known as thermogenic, it induces body heat. This means more fat burn and more efficient metabolism.  Cayenne Pepper also boosts the rate of fat burning, thus helping to cut down fat components.

3) Glucomannan


This component helps bring in the essential fiber component into the supplement. As we know, fiber is vital in controlling hunger.

  1. This contains a specific chemical structure that helps it to pass through the stomach intact. This helps to give the feeling of fullness and helps suppress hunger pangs and is very effective in weight loss.
  2. It helps in weight loss and body weight management by improving metabolism and decreasing the tendency to snack frequently, a habit that is associated with fat accumulation in the body.

4) Caffeine Anhydrous

This dietary fiber is included to provide the user with the knockout punch to achieve workout goals.

  • It helps improve focus and concentration. Mental alacrity and the ability to zone in on the task at hand with single-minded focus are essential to get through with punishing workout regimes.
  • It also helps with post-workout recovery of muscles as well as reducing pain and cramps.
  • It fuels the workout sessions with increasing fat burn to provide more energy and lose weight in the process.
  • It helps to stimulate the nervous system by inhibiting adenosine receptors. This contributes to more power-filled workout sessions.

5) Vitamin B6

This vitamin component in Instant Knockout has been known to be an aide to a healthy lifestyle.

  1. Also known as pyridoxine, it helps with fat oxidation (negative energy balance) and improves metabolism. This makes a difference in the manner in which the body produces energy to fuel its needs.
  2. Vitamin B6 helps in better assimilation of amino acids that play a vital role in muscle development.
  3. It keeps a check on fat levels thus helping in fat loss and building lean muscle mass.

6) Vitamin B12

The inclusion of this vitamin helps to provide more energy to the body.

  • This paves the way for high-energy workouts in the gym and better recovery.
  • It also boosts the immune system in the body.
  • Vitamin B12 can help elevate mood, thus improving overall wellness.
  • It helps in the better breakdown of carbohydrates and helps in protein synthesis, thus creating the perfect setting for lean muscle mass growth.

7) GTF Chromium

Not recognized much for its fat-burning capabilities, this component is a part of the Instant Knockout formula for multiple reasons.

  1. It is shown to control insulin levels in the body with effective management of carbohydrate intake. It also boosts metabolism and provides more energy to the body.
  2. Food cravings are controlled to a large extent with chromium and help in your weight loss goals.
  3. Chromium contains a protein, chromodulin, that helps in fat and sugar metabolism. This helps burn more fat while keeping the blood sugar levels in check.
  4. More energy is made available to the body which can be channeled towards energetic workout sessions, further aiding fat cut and lean muscle mass accentuation.

8) Zinc

The Metabolism-boosting properties of this component are well known.

There is so much its addition brings to the table.

  1. It helps give a boost to testosterone levels, which is known to encourage protein synthesis. Now, anyone who is familiar with bodybuilding and muscle mass growth will know the importance of protein synthesis in this matter.
  2. Zinc also helps turn carbohydrates, proteins, and fats into energy, thus helping fuel intense workouts. This action also helps burn fat more effectively.
  3. Studies have also hinted at better glucose metabolism with the inclusion of zinc in the diet.

9) Piperine


This is extracted from black pepper and helps the user in these ways.

  • It really ups the metabolism while helping in more efficient digestion helping you in losing weight and other potential health benefits. A slow metabolism makes it difficult for you to burn fat.
  • It generates thermogenesis, which is helpful in the fat burn as discussed already. It can also have a role in suppressing new fat cells from being formed making you burn more calories at rest.
  • More fat burning happens because piperine is known to turn on receptors TRPA1 and TRPV1 that aid accelerated fat burn and increases your metabolic rate.

10) Green Coffee Bean

Green coffee

Without the caffeine content of traditional coffee but with loads of other benefits, this component is basically an unroasted coffee bean.

  • Contains chlorogenic acid that helps slow down fat absorption, thus controlling fat in the body and increasing energy expenditure.
  • The same content helps to control sugar cravings as well as lower cholesterol levels. This positively impacts health. The user gains better parameters and overall good health.
  • Also, Green Coffee extract helps to cut unwanted body fat, and helps achieve a leaner body and weight loss. That is the ultimate goal, after all.
  • Green tea also contains L-Theanine amino acid which helps ease anxiety, and stress and reduce insomnia. In turn, this may help lower blood pressure.

Other ingredients in Instant Knockout include gelatin, HPMC, magnesium stearate, silicon dioxide, FD&C, and Red 40.

How does Instant Knockout work?

This powerful yet all-natural weight loss and fat-burning supplement have been created to burn fat effectively.

Its working mechanism is based on a three-pronged approach, namely boost metabolism, control hunger (or act as an appetite suppressant), and provide energy.

This is the healthiest possible approach to the stubborn problem of fat burn.

Instead of using chemicals to do this, Instant Knockout utilizes naturally occurring ingredients to allow the body to fuel its own physical excesses, thus paving the way for maximum gains – fat burn as well as gain in muscle mass.

I am going to write about each of these approaches in detail.

1) Boost metabolism

Instant Knockout fat burner helps to keep the metabolism in top order at all times, creating an environment of efficient fat burn going within the body.

This keeps the fat from accumulating in the body, instead of burning it effectively to provide high levels of energy to the user.

2) Control hunger

Instant Knockout is designed to include components that are high in fiber content and other ways to control these hunger pangs and cravings.

This creates an ideal setting to help in the weight loss process. This is what makes it the world’s most effective fat burner.

3) Provide energy

Instant Knockout includes ingredients that help to provide energy to handle heavy-duty workout sessions daily without losing focus. Which can help you lose body fat.

Instant Knockout Dosage

There is a detailed regime outlined on the website on the ideal spacing to take the Instant Knockout pills.

One needs to take four pills over the course of a day to maximize benefits.

  • First pill first thing in the morning.
  • Second pill before lunch.
  • Third pill in the afternoon.
  • Last pill before dinner in the evening.

This spacing and regimen give each pill adequate time to make its effect felt and to allow for maximum absorption and internalization in the body.

Each bottle of Instant Knockout contains a month’s dosage of 120 pills, each dosed at 75 mg.

Are there any means to stack Instant Knockout?

For those in the profession of MMA fighting or bodybuilding, one standalone product is never enough to address their different requirements.

They use a well-researched combination of different ingredients to focus on bolstering different aspects of their physicality.

Even for amateur users, there are different products that many use to stack the effects of Instant Knockout.

One may look at the Roar Ambition website to know about a different range of products. Most people go with the “Ultimate Shredding Stack”.

These may be for more energy and endurance, faster recovery, or mass gainers.

Depending upon what you are looking to achieve, it is possible to pick up two or three products for a more balanced approach.

Who should not use it?

As you have already seen from the ingredient list and detailed description, Instant Knockout contains naturally occurring components.

There are, however, certain sections of people who should stay away from this.

These include:

  • Pregnant or lactating women.
  • Those under the age of 18.
  • Anyone who is under prescription medications for some pre-existing condition.
  • Those suffering from any illnesses ought to consult their physician before beginning on Instant Knockout.
  • Anyone having allergies to any of the ingredients listed earlier.
  • Those who are sensitive to high caffeine dosages.

Cons: What I did not like

  • It is a caffeine-rich composition. So you might want to reduce your caffeine intake while using this supplement.
  • For the money-back offer to kick in, one needs to order a 3-month supply.
  • It is only available online, which could be a negative for some people.
  • You might want to ask ‘Is Instant Knockout Vegan friendly? Well, the ingredients are but the capsules aren’t. Instant Knockout contains gelatin, making it unsuitable for vegetarians or vegans.
  • At 4 pills a day, it needs the force of habit to take on a regular basis.

Instant Knockout Reviews from Customers

Full credit to the creators of Instant Knockout for having come up with such a product that finds endorsements at the highest levels.

Not only amateur users who are numerous in number, but Instant Knockout also has coaches and champion athletes on its user list.

I found John Dodson II, one of my idols in the flyweight category, who has benefited from Instant Knockout.

He has used this fat burner to cut off unwanted fat while keeping his muscle mass intact.

Knowing that was an instant confirmation for me to get started on Instant Knockout.

To bolster this was the fact that leading coach, Greg Jackson recommends this to get his champions in perfect shape.

Then there are ‘before’ and ‘after’ photos featuring amateur bodybuilders across the spectrum.

Take for instance Dan Mack from the UK who says:

“I ordered Instant Knockout a little hesitantly, after trying various fat burners previously which all promised fantastic results immediately but rarely work……I would highly recommend Instant Knockout to anyone struggling to stick to a plan, as much as a discipline is important, a well-engineered weight loss supplement makes a world of a difference.”


“I have tried many other supplements to aid me in my weight loss journey and nothing has even been comparable to what Instant Knockout can do! It has also helped me relax my eating habits”

Overall, though, there is an overwhelmingly positive response to Instant Knockout.

What I liked

  • Instant Knockout is a completely natural fat burner.
  • It is totally safe to use and will improve your body composition.
  • Boxers use it for its famed fat-burning constituents.
  • The composition of the product is such to aid stubborn fat reduction from all parts of the body and works to increase fat oxidation.
  • Regular usage gives a toned body akin to professional sportsmen and can help you lose weight.
  • It is packaged in the form of pills and all one needs to do is to take four of these throughout the day for the best results to boost digestive health.
  • If your body goals involve fitness and definition, Instant Knockout is definitely the answer.

  • There are many current athletes and sports professionals who are vouching for the efficacy of Instant Knockout and this helps instill confidence in potential users.
  • It also comes with a 90-day money-back guarantee and FREE worldwide delivery.

As one can see, the list of things to like about Instant Knockout is long.

Each of the points mentioned is a plus but what sealed the deal for me was the last point listed above – the fact that established professionals have benefited from using the product.

It is a fact that these people are guided by knowledgeable teams of coaches, dieticians, trainers, and others.

So, when they endorse a certain product, it says a lot about the legality, effectiveness, and quality of the product.

Insider Information

Some users have reported a massive high in energy levels right after starting on Instant Knockout.

This might take a couple of days to get used to and might lead to restlessness during sleep time.

I was on the watch out for similar effects and did feel highly charged up the first two days.

Soon, however, my body got used to it, and I am pleased with where I am now.

Another thing I wish to share with all my readers here is that while on Instant Knockout, they need to diligently continue their healthy diet and workout regime.

So that you’re burning more calories than you’re consuming.

It is not to be assumed that just popping pills 4 times a day will get you on the road to fitness as your body burns more calories.

Keeping your activity and discipline levels focused at all times is needed.

You have embarked on this journey for a reason – you need to stay committed to achieving the best results.

How good is Instant Knockout Supplement to female users?

Instant Knockout is a fat burner that is as good for men as it is for women.

Some women also worry if their hormonal balance will be disturbed using this fat burner.

It does not contain hormone boosters of any sort.

It is simply a fat burner.

This means, that anyone who has unwanted fat on them that they want to lose, can safely take Instant Knockout while continuing on their exercise regimen.

Thus making it one of the best fat burners on the market.

Buying Advice

I would advise everyone reading this to always buy directly from the official Instant Knockout website.

This is indeed the best place to get your supply of the product.

Why do I say so?

This is because:

  1. One gets the assured quality of genuine products when you buy Instant Knockout on the official website.
  2. There are always special discounts to be availed of here.
  3. One can rest assured that the 90-day money-back guarantee will be honored on website purchases.
  4. Payment is secure and safe on the website.

There is a list of countries that Instant Knockout does not deliver to, for various reasons.

This list is clearly mentioned on their website.

This is one more reason for users to first check the Instant Knockout website to find out if their country is among those which the company ships.

Another thing I would like to mention here to new users is to check the delivery timings to their particular country.

The website goes into great detail to mention expected delivery timings to all countries where they ship.

Why this is important is depending upon timings in a particular country, the user needs to plan the next shipment so that there is assured continuity.

The product needs to be taken regularly at the prescribed dosages and any break in this routine will affect the ultimate results.

Final Verdict

I was looking for an effective fat-burning method while staying on a healthy course.

Reports from users of varied products available on the market had added to my conundrum when I very tentatively began on Instant Knockout.

I am proud to state that my results have been nothing short of exceptional.

I have no qualms about recommending Instant Knockout wholeheartedly to everyone out there who wishes to achieve their body goals safely and naturally.

From my research, it’s way better than other fat burners out there.
