If you’ve done any research for yourself into so-called ‘fat burner’ supplements, you may have already come across Instant Knockout Cut.

Product website:

Instant Knockout Cut is marketed as a so-called ‘fat burner supplement‘. In case you didn’t know, a ‘fat burner’ is a blanket name which generally refers to food supplements that contain a range of ingredients including things such as vitamins, minerals and plant extracts.

Before we get started, it’s important to realise that, like most of the similar supplements out there, Instant Knockout Cut has not been proven to ‘burn’ fat on its own.

Instead, it’s simply a supplement which contains a range of ingredients, including vitamins, amino acids and herbal extracts, and is intended to be combined with a varied diet and healthy overall lifestyle.

It’s widely accepted that the main proven way to lose fat is to stick to a (sensible and well-managed) diet and exercise regimen in which you’re burning slightly more calories than you’re consuming. In other words, it’s about keeping in a slight calorie deficit over time.

With that all being said, Instant Knockout Cut is one of the more popular products on sale at the moment in this particular category of supplements. But is it all it’s cracked up to be?

Our friends over at Roar Ambition sent us a couple of bottles of Instant Knockout Cut so we could take a closer look and try it for ourselves.

In this Instant Knockout Cut review article, we’re going to take a detailed look at this supplement from all angles, paying particularly close attention to the ingredients formula and price.

So, let’s get right down to business and start taking a close look at the Instant Knockout Cut supplement.

Instant Knockout Cut – The Basics

As you’ve no doubt already gathered, Instant Knockout Cut, which is made by the UK-based company Roar Ambition, fits into the broader range of supplements commonly known as so-called ‘fat burners’.

Instant Knockout Cut contains a blend of ingredients, ranging from plant extracts to some essential vitamins and minerals. It also contains the stimulant Caffeine.

Each fist-shaped bottle contains 120 capsules, and the product is marked as having a “revolutionary” ingredients formula.

According to the official website, it was originally developed to help MMA fighters and professional boxers.

The Ingredients

The ingredients are obviously the crucial factor which determines whether a supplement is actually going to be useful or not.

So let’s kick this section off by taking a look at the exact ingredients in Instant Knockout Cut as stated on the official Roar Ambition website at the time of writing:

Instant Knockout Cut contains some of the most common ingredients found in supplements in this category. In total, Instant Knockout Cut uses nine active ingredients in its vegan-friendly formula.

Editor's note: Any health claims about the ingredients mentioned in this article are listed as authorised on the EU Register at the time of publishing. Additionally, you should carefully check the ingredients information shown on the official website of any product you're considering purchasing, as formulas may change from time to time and therefore may differ from what's shown on this page.

Here are some of the top ingredients in the product:

• Green Tea Extract – A very popular ingredient in supplements of this type. Not just a common hot drink, Green Tea is often added to supplements in the form of an extract and has some promising research behind it.

• Cayenne Pepper – Another common ingredient in this type of supplement. You’ll find it in many of the top products. Each serving of Instant Knockout Cut contains 100mg of Cayenne.

• Caffeine Anhydrous – This one needs no introduction. Caffeine is one of the most popular natural stimulants on the planet and coffee drinkers will know all about it. Instant Knockout Cut uses 300mg per daily dose, which works out as 75mg per capsule.

• L-Theanine – An amino acid which is found primarily in tea leaves. Each serving of Instant Knockout Cut contains 100mg of L-Theanine.

• Glucomannan – Another common ingredient for supplements in this category, this is a dietary fiber which usually comes from the root of the Konjac plant. Each daily dose of Instant Knockout Cut contains 1800mg.

• Green Coffee Bean – This is another very common ingredient found in many of the supplements in this category. Green Coffee Bean Extract is usually rich in a substance called Chlorogenic Acid. Each serving of Instant Knockout Cut uses 100mg of Green Coffee Bean extract.

There are a number of other ingredients in the Instant Knockout Cut supplement, such as B Vitamins, Vitamin D3 and Black Pepper Extract.

One plus point is that Instant Knockout Cut doesn’t use a proprietary blend. This means that the doses of each individual ingredient is specifically listed.

We like this because it essentially shows that the manufacturer is being transparent by allowing customers to see exactly what is in each capsule.

After all, you’re going to be putting this product into your body, so you’ll want to know exactly what’s in it.

Side Effects

Before taking any supplement, you’ll want to be sure that the product doesn’t contain any banned or risky ingredients. Instant Knockout Cut is essentially a food supplement which contains some plant extracts, as well as some Vitamins and Amino Acids and the stimulant Caffeine.

We strongly recommend that you speak to your doctor or a certified medical professional before taking any supplement for the first time.

You should not take this supplement if you are pregnant or breastfeeding, and you should consult your doctor before taking it if you have an underlying health condition or are taking any prescription medication.

One thing we found with supplements in this category is that many of them tend to be overloaded with stimulants such as Caffeine.

Instant Knockout Cut contains 300mg of caffeine per daily serving, and 75mg per capsule. This is a significant amount of stimulant content, and some people may want to reduce their caffeine intake from other sources while taking this product.

We’d also recommend not taking this product too close to bedtime due to its Caffeine content.

Ingredients such as Caffeine can cause side effects for some people, and that’s why it’s always important to seek advice from a certified medical professional before starting with any new supplement.

There’s a warning on the label saying that you shouldn’t take this supplement with any other high caffeine or high stimulant products.

How To Take It

The directions for taking Instant Knockout Cut are pretty straightforward. They simply say that you should take one capsule, four times a day, in between meals.

That’s fairly straightforward, but remembering to take it that often could be difficult for people with particularly busy lives.

As we mentioned above, we’d recommend taking the last dose not too close to bedtime due to the Caffeine content in this supplement. Indeed, the label says that you should not take Instant Knockout Cut within five hours of going to bed.


Instant Knockout Cut carries a premium price-tag, and there are certainly cheaper options out there.

The price for one bottle is currently £35 / $59 / €45 on the official website.

However, you can save money on the price per bottle if you’re willing to commit to buying more than one at a time from the official website.

The best deal is the four-bottle bundle. Check the official website for full details, as prices can vary from time to time.

Instant Knockout Cut Reviews

If you’ve done any research for yourself, then you’ll probably have already read some of the testimonials on the official Instant Knockout website.

One issue with Roar Ambition’s supplements is that they are only available to buy on the official website, so there are not reviews to be found on third-party retailers such as Amazon.

Generally speaking, manufacturers tend to post more positive reviews on their own official websites, so it is probably best to take what you see on there with a pinch of salt.

Of course, most of the reviews on the official site were largely positive, but this is probably not a surprise.

Instant Knockout Cut FAQs

In this section, we’ll answer some commonly asked questions about Instant Knockout Cut.

• Is Instant Knockout Vegan Friendly?

Yes. Instant Knockout Cut’s new ingredients formula has been updated to be suitable for both vegans and vegetarians.

• Can you buy Instant Knockout Cut at Amazon or GNC?

No. Instant Knockout Cut is currently only available to buy directly from the manufacturer on the official website.

You won’t find Instant Knockout Cut for sale at Amazon or GNC or at other stores at the moment. If you do find Instant Knockout Cut for sale elsewhere, it may not be an authentic product.

• How much Caffeine is in Instant Knockout Cut?

Any Negatives?

As with most food supplements, there are some potential drawbacks.

Firstly, and as mentioned above, you can only buy it on the official website at the moment, meaning that you won’t find it on other sites such as Amazon or in the shops.

It’s also a premium-priced product. At the time of writing, one bottle costs £35 / $59 / €45, which might be out of some people’s budgets.

Roar Ambition do run promotions on the official website where you buy three bottles and get a fourth free, and that includes free shipping.

If we were to be picky about the ingredients formula, we would reduce the Caffeine content. 300mg (75mg per capsule) is a significant dose of the stimulant and your Caffeine consumption can add up if you’re consuming it from other sources as well.

It’s also worth noting that this supplement contains a fairly hefty dose of Vitamin D3 (1800IU per four capsules, which is 450IU per capsule). This is not necessarily a bad thing, but it’s a good idea to keep your total intake of Vitamin D3 from all sources under review and in check, especially if you’re consuming it from other supplements. As we mentioned above, it’s best to speak to your doctor before taking any supplement for the first time to discuss the pros and cons of the ingredients and their doses.

Anything Else To Consider?

Just remember, supplements like this will not work wonders on their own. It’s important that you have realistic expectations if you’re thinking about trying a supplement in this category.

The first thing you should do before considering any supplements like this one is to make sure that you’re eating right by sticking to a varied, balanced diet, and pairing it with a sensible exercise plan.

Supplements can help to prevent shortfalls in certain important nutrients, but you should always make sure that you’re doing the right things in the gym and the kitchen before expecting results from a so-called ‘fat burner’ supplement.
