As a fitness instructor, I work with a lot of high-performance athletes on a daily basis. It’s usually a mix of bodybuilders and just average people who need some help with their health, and fitness goals.
Recently, I’ve also started working with MMA fighters, and one of my clients recently introduced me to Instant Knockout. While I’m a fan of fat burners, I’m also very cautious of all the dodgy weight loss supplements out there.
But because of the results I have witnessed, I decided to do some more research and look into the ingredients with a dietitian to put together this detailed Instant Knockout review.
What is Instant Knockout Cut?
Instant Knockout is a cutting-edge weight loss supplement that claims to help you cut and shred.
The company behind this product is Roar Ambition, and their goal is to make the most effective fat burner using natural ingredients that are scientifically proven to help athletes get rid of fat, build more muscle, and support weight loss.
While it's originally developed for MMA fighters and professional boxers, their revolutionary formula works well for average people who just want to bulk up a bit or lose weight.
Update Aug 2021** Instant Knockout gets rebranded to Instant Knockout Cut. Some ingredients like zinc, chromium, and green coffee bean extract were removed and replaced with L-theanine and vitamin D3. They also moved from red capsules to clear capsules to make the product cleaner by removing the Red40 food dye since customers were asking for that.
What Makes Instant Knockout Cut Unique?
If you’ve followed any health and fitness page on Facebook or you just happen to read posts about muscle building, then you’ll quickly notice a load of suspicious fat burners on your news feed.
The fat burning industry is a huge business, and unfortunately, there are too many black sheep promising to help you lose weight quick.
However, my suspicions about Instant Knockout were instantly reduced when I saw that there was a lot of backing from MMA fighters and coaches like Diego Sanchez and Greg Jackson.
We’ll get to the details of Instant Knockout's nutritional label below, but I can say here that a lot of thought has gone into creating this product.
What Are The Benefits Of Instant Knockout Cut?
I wanted to focus this Instant Knockout review on its nutritional label. The brand claims to have an all-natural list of ingredients that could potentially help you with weight loss without the unnecessary side effects.
I'll discuss those ingredients and what they do in detail, but let's talk about the product claims first.
1. Fat Loss
This might be an obvious benefit of fat burners, but it really can be hit and miss with these types of supplements. However, Instant Knockout contains ingredients that not only help with fat burning and losing weight but also in controlling the process that stores body fat in the first place.
After 3 months of using Instant Knockout, it's definitely one of the products I would recommend to my clients who are trying to cut. It helped me reach my goal days early during my two cutting phases.
Most users online also noticed that they were losing fat in as fast as 2 weeks, while other users took a month or two to reach their desired weight.
2. Increased Energy Levels
When your body burns more fat, then more energy is released to fuel different parts of your body. But what I found in many different Instant Knockout reviews is that people also noticed a good increase in mental energy levels and focus.
This means that it may help with workouts by staying motivated, but also at work and school when you need your brain to work on complex problems.
I noticed higher energy levels throughout the day just within the first week as well as better focus and mental alertness at work.
- Strong dosage of caffeine from green tea extract for mental performance and thermogenic effects for weight loss
- 10 mg of zinc boosts testosterone production for more muscle growth
- Nice dose of glucomannan to help as an appetite suppressant
- Includes cayenne pepper which helps as a fat burner to shed off more calories
- You’ll need a reminder to take 4 pills per day
OK, with all these pros and cons, we can say that Instant Knockout promises good stuff. What about the negatives?
Are There Any Side Effects?
Fat burners and weight loss pills have had quite a bad reputation.
Sure, a lot of them may be effective at weight loss, but many can also cause upset stomach, which isn’t ideal to stay motivated on a weight loss program.
The good news is that because it is made of the most natural ingredients my dietitian has encountered, the side effects really are limited.
The one area where you may want to be careful with Instant Knockout is the 300 mg of caffeine on a full dosage, which is quite common with fat burners and weight loss supplements.
That’s roughly the same amount you get in 2 large coffees. So if you’re planning out your daily intake of Instant Knockout, then you may want to skip a few trips to Starbucks.
Weight Loss Ingredients And Their Effects
Now that you have a good picture of the product's benefits and side effects, let’s take a closer look at how effective the ingredients in Instant Knockout are at stimulating energy levels, fat oxidation, weight loss, and appetite suppression.
1 - Caffeine Anhydrous
According to my dietitian, caffeine anhydrous is one of the most closely studied thermogenic ingredients.
This is probably why Roar Ambition decided to make it a major feature on Instant Knockout's ingredients list.
While some athletes have trouble with caffeine anhydrous as a stimulant, you should note that there is very good scientific evidence  backing up the claim that it encourages your metabolic rate to burn fat and lose weight.
I was hesistant on taking this product at first because of the caffeine level, but I lost around 1 to 2 lbs just within my first week.
2 - Green Tea Extract
I used to force myself to drink some green tea every day. It’s just not a taste I enjoy, but I totally understand the antioxidant benefits it provides.
But, when I found that you can get a fat burner that contain green tea extract, I jumped on the opportunity.
Instant Knockout only contains a small amount of caffeine from its green tea extract, but I found a very interesting study that highlighted a direct link to body fat oxidation .
3 - Cayenne Pepper Seeds
Cayenne pepper is a well-known thermogenic, but what I found more interesting was the company’s claim that it “boosts insulin sensitivity helping improve the way you store carbs.”
Not surprisingly, at this stage of my research, I was able to find supporting studies of this .
One of the main benefits of having better insulin sensitivity is easier and faster fat loss, which may have helped during my two cutting phases.
4 - L-Theanine
Naturally occurring in teas, this amino acid is a common ingredient in many dietary supplements. It is scientifically proven to improve memory and focus for longer periods of time as well as enhance sleep quality in healthy adults .
Since some supplements contain stimulants like caffeine which can cause jitters, taking it with L-theanine is said to promote relaxation to eliminate energy crashes.
The combination of caffeine and L-theanine may also improve focus during highly demanding tasks .
This may explain why I didn’t experience any energy crashes during and after workouts. I also noticed that I sleep better than usual and I feel more rested to push through a tough workout the following day.
5 - Glucomannan
This product contains glucomannan extract sourced from the konjac root, which was new to me.
Unlike most of the other ingredients, this is not included based on an ability to burn fat in an effective way.
Instead, glucomannan helps to suppress appetite by delivering a good amount of dietary fiber to make you feel fuller for longer.
True enough, I had better appetite control, which helped me cut out snacking in between meals and most especially at night.
6 - Piperine
This is another one of the very versatile Instant Knockout ingredients that has a lot of nutritional value.
It’s included in many products, and my dietitian goes as far as saying it is required to make absorption rates higher for both macro and micronutrients.
Piperine (from black pepper) can enhance the absorption or bioavailability of certain compounds, such as curcumin from turmeric. -ConsumerLab.com
7 - Vitamin B6
We all know how important vitamins are, and your daily nutrition intake has to cover a very wide range of them.
Vitamin B6 has been added due to a claimed link to the way cells repair and reproduce, which is an important factor in muscle building .
Just check if your multivitamin also contains B6, as you may want to avoid taking too much.
8 - Vitamin B12
Instant Knockout contains more vitamin B12 than you need every day.
Most people will link this vitamin to influencing your red blood cell count, but vitamin B12 also helps with fat oxidation and metabolism .
9 - Vitamin D3
Known as sunshine vitamin, vitamin D3 helps strengthen bones and muscles, improve cognitive function, and enhance heart health.
It may also lower blood pressure levels, but new research suggests that it may also give you the boost you need for workouts.
A recent study looked at how higher vitamin D levels are linked to better cardiorespiratory fitness, which may help you exercise harder and longer .
Low vitamin D levels are associated with higher risks for bone fractures, which is one of the many things you don’t want to happen after a tough workout.
When Should You Take Instant Knockout Cut?
Every time I recommend weight loss supplements like fat burners, one of the first questions is always “what time of day should you take them?”
Instant Knockout is designed to provide maximum nutrition value throughout the day by splitting your intake into 4 pills.
This spreads out the fat burning effects and delivers a more constant stream of extra energy.
One thing I noted in a few reviews about Instant Knockout was that athletes suggested setting a reminder on your phone or getting into the habit of taking a capsule every time you eat a meal.
I make it a habit to take one capsule every meal, including my afternoon snack, because taking it with food may help increase absorption according to the manufacturer.
Some also mentioned that because of the caffeine from green tea extract, you might have to avoid taking it too late in the day.
Is it Suitable For Women?
For women, weight loss is often a higher priority than muscle gain. The good news is that Instant Knockout is not specifically a muscle building product. This means that women can take full advantage of effective fat burning properties for increased energy and weight loss.
One thing I would caution, though, is that the amount of caffeine in Instant Knockout is quite high when the full volume is taken each day. You may want to start with just 2 or 3 capsules a day.
Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two "energy shot" drinks.
Where Is The Best Place To Buy Instant Knockout Cut?
I always recommend buying directly from Instant Knockout's official website. It is the only place that it’s officially available, and with so many counterfeit products on the market, there are too many health risks you could expose yourself to.
This is also the only way you can take advantage of the money-back guarantee, as well as some very good bulk-order prices. Since I ordered my first supply of Instant Knockout, I now always go for the “Ultimate Shredding Stack” from the official website to save money.
If the Instant Knockout doesn't work for you or you simply want to try a month's supply, you can always take advantage of their 90-day money-back guarantee.
Instant Knockout Cut Cost
Each bottle has 120 capsules which would last for a month with a recommended daily dosage of 4 capsules.

Fat Burner Alternatives
PhenQ is one of the leading fat burners in the market today that aims to burn stored fat and stop fat production by accelerating your metabolism through a trademarked formula called α-Lacys Reset®.
In a full daily dose, it contains half the caffeine you get from Instant Knockout, making it more suitable for those who are sensitive to stimulants. It’s also vegan-friendly like Instant Knockout and it gets cheaper per bottle (as low as $38) when you buy a package.
Marketed as a female fat burner, LeanBean is one of the most effective vegan-friendly fat burners that does not contain any stimulants. It works to help burn excess fat and suppress appetite through a higher dose of glucomannan (3 g per day) and other all-natural ingredients like chromium, zinc, and turmeric. Unlike Instant Knockout which is designed for performance athletes, LeanBean has a caffeine-free formula that’s perfect for women who just want to lose some unwanted fat. They also sell at the same price so it all comes down to your fitness goals.
Do You Take Instant Knockout With Food?
Yes, you should aim to take Instant Knockout with food. This is generally a good approach for all supplements like a fat burner to reduce the chance of an upset stomach and make the product more effective.
Is Instant Knockout a Thermogenic?
Yes, Instant Knockout is a thermogenic, which means it increases your core body temperature slightly by boosting your metabolic rate which results in possible weight loss.
It contains green tea extract, cayenne pepper, and green coffee bean extract which are known for their thermogenic effects that may help you lose weight.
How Do You Take Instant Knockout?
Take 1 pill of Instant Knockout 4 times per day with meals and snacks. Because it’s in pill form, it’s easy to adjust your intake up or down as required to achieve your weight loss goals.
Does Instant Knockout Fat Burner Work?
Yes, Instant Knockout fat burner does work, and you can see this in all the positive product reviews online. Of all the fat burning supplements available right now, this is the one that has the most scientific research backing up its powerful effects.
Can I Stack Instant Knockout With Other Supplements?
Yes, you can stack Instant Knockout as a fat burner with other supplements. However, because the recommended serving of Instant Knockout has about 300 mg of caffeine, you have to be mindful of the caffeine content of the products you plan to stack it with.
How Long Does It Take For Instant Knockout To Work?
It varies as some users lose weight in just a few weeks while others take a month or longer. It is recommended to give the product 30 to 60 days to assess whether or not it works for you.
Is Instant Knockout FDA-Approved?
Like any other fat burns, Instant Knockout is not FDA-approved. However, it is regulated by the FDA which works against adulterated or misbranded dietary supplements.
Is Instant Knockout Cut Worth The Investment?
After 3 months of trying the product out for this Instant Knockout review, analyzing the content with a nutrition expert, and reading through hundreds of reviews, I have to say that this fat burner is my personal favorite, and the one I recommend to my clients.
The weight loss effect is noticeable, and I have tried it during 2 cutting phases, where each time I reached my goals a few days early.
You can purchase 3 bottles of the product and get a free bottle plus free shipping from their official website.
Once you have tried it out for a few weeks, make sure you get in contact with us on social media or use the contact page on this site.
