Overview of Instant Knockout

Instant Knockout Review

Instant Knockout is owned by Roar Ambition, a premium sports supplement brand. Headquartered in the UK, Roar Ambition was founded by Robert Parker in 2014. His goal for Instant Knockout Cut, he says, was to “make it the number one fat-burning supplement on the market”.

It seems as if he’s well on his way to reaching his goal. After doing a Google search on the supplement, Instant Knockout Cut popped up on multiple lists of top fat-burning supplements. At only 35 years old, Parker has been wildly successful. 

The media hype is all well and good, but is it warranted? To find out, I’ll take a deep dive into Roar Ambition’s star product, Instant Knockout Cut. First, we’ll go over some highlights:


  • Helps you lose weight and gain muscle
  • Increases metabolism
  • Vegan-friendly
  • Made with natural ingredients
  • Used by pro-athletes
  • Free US and UK delivery when you buy two or more bottles

Things are looking pretty good so far. Let’s get started with this Instant Knockout review!

Instant Knockout Review

So you’ve been hitting the gym for a few months now, and have even adjusted your diet to include more protein and veggies, but the weight loss isn’t happening as quickly as you’d like. If this sounds like you, you’re not alone.

Studies[1] have shown that about 42% of adults have reported trying to lose weight. But, if you’ve ever tried to go on a diet, you know that it can be challenging. Even when people do manage to stick to them, the lost weight tends to eventually reappear[2].

There are a range of factors[3] that can be responsible for this slow change, such as a lack of genetics and hypothyroidism. While you can’t do much about that first one, you can do things to boost your metabolism.

This is where a weight-loss-promoting supplement can come in handy: Instant Knockout Cut can help you not only lose weight but build muscle and speed up your metabolism, helping you to reach and maintain a shredded new look.

Instant Knockout Cut is described as a weight management supplement, but scientifically it can be described as a thermogenic, which literally means it’s heat-producing.

When the body produces more heat, it means it’s burning more calories and boosting its weight loss capabilities. 

This supplement’s thermogenic properties come from its list of natural, vegan-friendly ingredients, which we will do a deeper dive into later.

This supplement comes in capsule form, so you don’t need to drink any nasty powders. Instant Knockout advises taking four capsules daily to help you lose weight and increase your metabolism. 

Pick up a bottle of these Instant Knockout Cut today for $59, which gets you a one-month supply of 120 capsules. Or, if you really love the product, you can get three bottles for $185 and get the fourth one for free!

Who Is Instant Knockout For? 

Instant Knockout Review

Although Instant Knockout Cut was originally designed for professional athletes, it can be used by anyone over the age of 18 who’s looking to lose weight and get shredded.

Whether you’ve just started your weight loss journey or are having trouble losing that last 5 lbs, this thermogenic supplement is for you.

This Instant Knockout review found that men and women can use this supplement. In the brand’s own words: “We all struggle at times to keep excess weight at bay, and that’s why Instant knockout Cut was born. It was designed for the pros, but now it’s available to you.”

What Are the Benefits of Instant Knockout? 

Instant Knockout Review

Instant Knockout Cut is a weight management supplement made with natural ingredients. Each ingredient has weight-loss-promoting or thermogenic properties. Together, they come with four main benefits:

  1. Weight loss
  2. Increased metabolism
  3. Less hunger
  4. More energy

How Does Instant Knockout Work?

Instant Knockout Review

Instant Knockout Cut works by boosting your metabolism to help you lose weight. The product accomplishes this thanks to its thermogenic ingredients, such as caffeine and cayenne powder.

The ingredients work together to produce “an intense, thermogenic burn”, helping you to move closer to your dream body.

What Are the Ingredients In the Instant Knockout?

Instant Knockout Review

Now that you know how it works and what it can do for you, how exactly is the brand doing all of this? Let’s take a look at the key Instant Knockout ingredients:

  • Vitamin D3: Though commonly known as the sunshine vitamin, vitamin D has a whole other side. One study[4] showed that higher vitamin D levels are associated with greater weight loss caused by dieting
  • Vitamin B6 and B12: the B vitamins are important for energy metabolism
  • Glucomannan: a type of fiber extracted from the roots of certain plants, glucomannan can help with your health goals. Studies[5] have shown that supplementation with glucomannan can help control body weight and even reduce blood cholesterol and fats
  • Green tea extract: not only is green tea a warm, soothing drink, it can also help you lose weight! One study[6] showed that women with obesity who took a high dose of green tea extract for 12 weeks experienced significant weight loss, lower cholesterol, and a smaller waist
  • Caffeine: in addition to being the thing that helps you get out of bed in the morning, caffeine has long been known to have thermogenic properties. One study[7] showed that caffeine intake increases the body’s expenditure of energy
  • L-theanine: this amino acid is naturally found in green tea[8] which, as described above, can help with weight loss
  • Cayenne powder: this superstar ingredient does more than just add a kick to your favorite foods. Like caffeine, cayenne[9] has been shown to increase the body’s energy expenditure, meaning that more calories are burned and more weight can be lost
  • Black pepper extract: this ingredient is also known as piperine. While evidence from human trials is lacking, one study[10] conducted on mice showed that piperine, in combination with curcumin, may help to increase fat loss

The capsules also contain vegetable cellulose, microcrystalline cellulose, silicon dioxide, and magnesium stearate.

How to Take Instant Knockout and Dosage

Instant Knockout Review

According to Instant Knockout, you should take one capsule of Instant Knockout Cut four times each day with a glass of water to reap its benefits. The brand recommends taking each capsule before a meal.

Instant Knockout Side Effects

Instant Knockout Review

This Instant Knockout review found that due to the caffeine found in the supplement, you may experience difficulty falling asleep. To avoid this, the brand recommends taking your last capsule of the day at least 5 hours before bedtime.

If you don’t normally have caffeine, you might also experience headaches.

Instant Knockout Reviews: What Do Customers Think?

Instant Knockout Review

I’ve now taken you through a detailed review of Instant Knockout Cut, and honestly, it looks pretty promising. But, science isn’t everything.

I wanted to hear from real customers to know whether or not the product delivers on its promises. To do this, I took to the internet to find reviews.

First, I went to Instant Knockout’s website. There, I found only 6 reviews, but they all provided 4 or 5-star ratings. One happy customer said:

You can have the training and the diet, but you’re still going to be missing a part… if you use Instant Knockout and apply diet and training, you’re going to get maximum results.” 

Another customer, a single mom who had been out of the gym for years, was seriously impressed with Instant Knockout:

Within three weeks of taking Instant Knockout Fat Burners, I have started to see amazing results and feel sexy and confident again. I have recently got back on to the dating scene and these are truly helping me get my confidence back.”

Next, I headed to Roar Ambition’s website, Instant Knockout’s parent company. Here, I found an average rating of 5 stars from 9 reviews.

One customer, who rated the product 4 stars, had this to say: “Not only has Instant Knockout helped me to lose weight, it has also suppressed my appetite. I have the bug for the gym now and highly recommend using these fat burners. I will be re-ordering more as I am still not at my goal just yet.”

The website is also full of testimonials, where many people have shared their Instant Knockout before and after results. Here, you can take a look at what the product can help you achieve. 

Because Instant Knockout Cut is only sold on their and their parent company’s websites, I found it difficult to find third-party reviews. However, the reviews that I did find seem to point to the fact that the product is effective.
