What is Instant Knockout? Is it Legit?

Instant Knockout is a dietary supplement designed to promote fat burning for faster weight loss and muscle building. The supplement was initially developed for MMA fighters, but the brand made it available to the general public too. 

Instant Knockout gives users the opportunity to look fighting fit without starving themselves or failing to resist cravings. 

One of the most well-known names in the MMA world, Diego Sanchez, endorsed Instant Knockout and confessed he dropped two weight classes just by using this product. His story is available on the official Instant Knockout website.

Instant Knockout Ingredients

As mentioned above, Instant Knockout supplies the body with ten natural ingredients to exhibit its effects. Let’s take a look at these ingredients below.

Green tea extract

Green tea is considered one of the healthiest beverages in the world. Health benefits of green tea are numerous, and weight loss is one of them. In fact, many weight loss and fat-burning products nowadays feature green tea in the formula. It’s safe to say green tea is the star of Instant Knockout’s formula. The benefits of green tea are down to active compounds catechins, but also caffeine content. The purpose of green tea in this formula is to promote fat burning, speed up metabolism, and promote weight loss and keep it off.

Cayenne pepper seeds

Cayenne pepper seeds contain capsaicin, an active compound with tremendous health potential. Capsaicin improves insulin sensitivity and exhibits thermogenic effects. In other words, it can speed up your metabolism and lead to fat burning. Additionally, capsaicin improves energy expenditure and promotes fat oxidation. It's also useful to mention cayenne pepper seeds are abundant in vitamins A, C, and B6, all of which are needed for overall health, immune system, and energy levels.


Chances are you have already come across the term glucomannan, but didn’t know what it was actually. Glucomannan has become a popular ingredient in weight loss products. It is a fiber that enlarges in your stomach. That way, glucomannan is able to suppress your appetite and curb cravings. Glucomannan improves your digestion. After all, the importance of good and healthy digestion is largely underestimated even though it’s crucial for weight loss.

Caffeine anhydrous

Caffeine anhydrous is made from the seeds and leaves of coffee plants. The word "anhydrous" means "without water." Basically, caffeine anhydrous is obtained after harvesting when caffeine is extracted from the plant matter and then dehydrated. The result is a highly concentrated caffeine powder. Caffeine anhydrous is a stimulant and gives Instant Knockout users more energy and power. That way, they have more strength and endurance to go through the workout routine and get the most out of it. Another role of caffeine anhydrous is to keep you focused, but also to reduce fatigue. The energy boost delivered by caffeine anhydrous promotes fat burning, which is particularly important if you have a lot of stubborn fat around the abdominal area to lose.

Vitamin B6

Vitamin B6, or pyridoxine, is significant to the metabolism of protein, fat, and carbohydrates. Your body also needs this micronutrient to produce red blood cells and support the functions of neurotransmitters. This vitamin also improves mood, promotes brain health, and decreases inflammation. In a nutshell, vitamin B6 supports general health and wellbeing. At the same time, it improves the way you synthesize energy and directly contributes to fat burning by increasing metabolic rate. Vitamin B6 works to promote the absorption of amino acids, which help you tone and build muscles.

Vitamin B12

Vitamin B12, or cobalamin, plays a crucial role in the production of red blood cells and DNA. The metabolism of every cell in your body depends on vitamin B12 because it takes part in energy production and synthesis of fatty acids. You need this vitamin to stay healthy and function properly. This micronutrient helps transform food into useable energy, supports metabolic function, maximizes protein synthesis, and helps improve the digestion of carbohydrates. Vitamin B12 intake allows you to get the best results from workouts, supports toning and building muscles, and keeps your energy levels high. Supplementation with vitamin B12 is important because many people don’t obtain necessary amounts from their diet alone on a daily basis.

GTF Chromium

GTF chromium is underrated despite its incredible health potential. Chromium is an essential trace mineral that improves insulin sensitivity and has the potential to enhance the metabolism of fat, protein, and carbohydrates. Additionally, this trace element increases energy levels and may also decrease food cravings. Since chromium can speed up metabolism, it allows you to burn more calories and fat. Chromium is able to provide these effects thanks to chromodulin protein, which works to improve the metabolism of fat and sugar, thus producing more energy that you can use in the gym.


Zinc is one of the most important minerals for your body. It is necessary for the proper function of the immune system, takes part in cell division, cell growth, promotes wound healing, and participates in the breakdown of carbohydrates. Moreover, zinc is crucial for testosterone production and male sexual and reproductive health. This is important because men tend to lose testosterone as they're getting older, and this process is only accelerated with an unhealthy lifestyle. Zinc in Instant Knockout helps men avoid this problem. After all, more testosterone, you have equals more energy and bigger muscles.


Piperine is the alkaloid responsible for the pungency of black pepper. The main purpose of piperine in this formula is to enhance the absorption of other ingredients. It can also support your metabolism, promote healthy digestion, and elevate thermogenesis. Additionally, piperine acts on TRPA1 and TRPV1, fat burning receptors in the body, to suppress fat cell accumulation and elevate energy metabolism.

Green coffee bean

Green coffee is raw, unroasted coffee, which, unlike regular coffee, is not a stimulant. It contains chlorogenic acid, which slows down the rate of fat absorption from food. Other benefits of this compound include reduced cravings for sugary foods and the potential to lower cholesterol.

Lab Tests and Results

The official website doesn’t mention lab tests carried out by the brand and its results. 

That being said, they included links of clinical trials and studies that confirm the effectiveness of ingredients they chose for the formula of Instant Knockout. 

This information is important because a vast majority of brands don’t include any evidence that supports the effectiveness of the ingredients and confirms the claims they’ve made are accurate.

To return unwanted items, the customers are encouraged to contact customer support.

How Does Instant Knockout Work?

Instant Knockout relies on ten powerful ingredients to burn fat, promote weight loss, and support muscle building or toning. The supplement has a triple approach toward fat burning.

First, it speeds up metabolism, which then burns more calories and fat. Instant Knockout works to boost metabolism so that you keep burning calories even when resting. This way, the product solves a common problem that makes it difficult for people to slim down – slow metabolism. Not only does Instant Knockout promote fat burning, but it also activates the Alpha-2 receptor to stop fat accumulation.

Then, Instant Knockout decreases hunger cravings. Almost all people have cravings, and they’re usually for unhealthy food. Many men and women can’t resist and end up eating those foods, especially at night. A constant need to eat something leads to weight gain and doesn’t allow you to burn fat or build muscles. By taking Instant Knockout throughout the day, men and women find their appetite is suppressed, they no longer have cravings, and thereby eat less. 

And finally, Instant Knockout increases energy levels so that you can easily do cardio, get most out of your workout routine, walk, and stay motivated. After all, it’s not uncommon for people to feel their energy levels are low, and they have no desire to do anything, let alone stay active. Low energy is also a result of slow metabolism. Instant Knockout helps users navigate their way around this problem. 

How to Use Instant Knockout?

Each red capsule contains 750mg and optimal results depend on proper intake. 

According to the brand, you need to take one capsule four times a day. Ideally, you should take one capsule first thing in the morning, one before lunchtime, one in the afternoon, and one before the evening meal.

The premise behind this schedule is that four equal doses scheduled throughout the day allow you to burn fat for a longer period of time.

An example given on the website is to take one capsule at 8 am, followed by one at 11 pm, then at 2 pm, and the last one at 5 pm.

Who Should Use Instant Knockout, and Who Should Not?

Instant Knockout is created for men and women alike. Although the product was primarily intended for pro athletes, boxers, and bodybuilders, the brand says it’s suitable for all people older than 18 looking to decrease body fat. 

However, Instant Knockout is not for women who are pregnant or breastfeeding. Men and women who have a medical condition or are taking medications should be cautious too. If you have some disease or take medications to manage it, make sure to consult a doctor before buying Instant Knockout.

Instant Knockout Side Effects

The main reason why many fat burners induce a wide range of side effects is excessive intake. Some people also experience adverse reactions due to high amounts of stimulants found in these products. 

This fat burner could be different, though. The brand doesn’t list the side effects of Instant Knockout as they dub it safe for consumption. Additionally, users haven’t reported adverse reactions, either. 

Although users claim they didn’t experience jitters, you should still stick to the recommended dosage. Avoid taking more than recommended, especially if you bear in mind this fat burner does contain stimulants.

Instant Knockout Reviews: Before & After 

User reviews paint a positive picture of Instant Knockout. Customers report fast weight loss and greater energy levels, all of which have improved their quality of life.

Dan said:

“I ordered Instant Knockout a little hesitantly, after trying various fat burners previously, which all promised fantastic results immediately but rarely worked.  I found the price was not overly excessive, especially for a month’s supply, and I was sold on the testimonials from professional athletes and MMA fighters.

Initially not expecting much, I started on day one with my morning pill just before breakfast. Within ten minutes, I felt full without taking a bite. Naturally, I was a little surprised as I did not expect the appetite suppression to take effect so quickly.

I continued throughout the course, sticking strictly to my diet and consuming the four pills daily. I have since started the same plan again to really pin down the difference on and off Instant Knockout, there is clearly a big difference, and my most recent eight-week plan has been much tougher without the appetite suppression.

All in all, I would highly recommend Instant Knockout to anyone struggling to stick to a plan, as much as a discipline is important, a well-engineered supplement makes a world of difference.”

Katie wrote:

“When I was younger, I didn’t care about fitness, and my main hobby was binge eating.

Five months after I had my first baby, someone took a photo of me, and I recoiled in horror.

How had I not noticed that I had gained so much weight?! I stepped on the scales, and at a small 5ft3in, I weighed nearly 200lbs! I started exercising and reduced my calories and went on to have another baby five months ago.

Through my second pregnancy, I gained 40lbs, and once again, I was miserable. I lost a few pounds and then suddenly hit that dreaded brick wall, I was eating clean and exercising, but the pounds just weren’t shifting, I was devastated.

I tried different types of fat burners, meal replacement shakes, and nothing worked. Then my partner, who was cutting at the time, found the instant knockout website.

He ordered it for himself, and the weight was dropping off him, so I thought I would give it a try, and it is the best thing I could have done.

I feel great, I have more energy to push harder during workouts and finally thanks to instant Knockout I have reached my goal weight!”
