by Michael Davis

The demand for supplements is growing faster than ever. Manufacturers are in a race to come up with a better and more effective supplement to answer the demands of their consumers.

It is no wonder why the segment for metabolism booster is dominated by only a few brands. It is more targeted to a specific type of population who wants a fit body like athletes.

Instant Knockout is one of these metabolism boosters that has captured quite a following. This supplement was developed for professional boxers and mixed artists. Since it showed significant results, the product was made available to all types of athletes and across all genders.

Do you want to find out more about the product? This Instant Knockout review will shed light on this exclusive metabolism booster, how it works, its benefits, and if there are possible side effects.


Instant Knockout Benefits

Instant Knockout contains all-natural ingredients that are guaranteed to make you lose weight and develop a fit physique like an MMA fighter.

Here are the benefits when you include this supplement in your regimen:

1. Weight Loss

It is an obvious benefit for metabolism boosters but not all supplements can deliver the results. The green tea extract content of Instant Knockout helps promote weight loss. With many studies and researches conducted on the effects of green tea on weight loss and weight management, it is safe to assume that this supplement is effective when you want to lose excess fat.

2. Increase in Energy Levels

When the body is burning more fats, then more energy is released into the bloodstream to fuel different parts of the body. What makes Instant Knockout even better is aside from providing more energy, it also increases mental energy to make you alert and more focused. It does not happen with other supplements where you may lose your mental acuity and lose focus because all the energy is spent on your body.

3. Suppresses the Appetite

Many people often struggle in extending their fasting period during the cutting phase. This is crucial because they need to put their body into ketosis to convert the fats as an energy source. However, the more you starve yourself, the more hunger hormones are released in your system. When you are taking Instant Knockout, it will control the hunger pangs by controlling your cravings and appetite.

4. Increase in Testosterone Levels

Another benefit of using this supplement is an increase in testosterone levels. It does not directly introduce the testosterone in the body. Instead, the ingredients present in the supplement like Zinc helps boost testosterone production.

Instant Knockout is classified as a fat burner supplement that is initially designed for athletes who are into boxing and mixed martial arts to lose weight safely and effectively.

This supplement is manufactured by Roar Ambition, a company specializing in supplements and based in London. According to the manufacturer their main customers are mostly males between the age of 21 to 30.

Most customers attribute their loyalty to the brand for its fat-burning and testosterone-boosting quality. The supplement helps them to build muscles and stay fit.

How to Use Instant Knockout?

For Instant Knockout to be effective, you should follow the suggested dosage for the product. Each bottle of this supplement contains 120 capsules. The manufacturer recommends that you take the supplement four times a day, preferably with every meal.

Timing is important in taking metabolism boosters to get the best results. This supplement is designed to provide maximum effects throughout the day, hence it is spread out. The fat-burning effects should be consistently delivered for the body to have a constant source of energy.

The best times to take it will be during the morning, before taking your lunch, in the afternoon, and right before you take your dinner. Because this supplement contains caffeine, it should not be taken with other supplements that contain stimulants.

It is also not recommended for people who are under 18 years old. To make sure that you are safe, those with pre-existing conditions should consult with their physician before including this product on their supplementation.

Does Instant Knockout Work?

Instant Knockout is an effective weight loss supplement that works by increasing the body’s metabolism. It works in three ways as follows:

1. By increasing the metabolic rate of the body

Our body needs the energy to function. When our metabolic rate is low, it does not burn the fat and it accumulates in the body. In Instant Knockout, the ingredients in the supplement boost its natural metabolism. With an increase in metabolism, it can burn more calories and even excess fats more effectively.

2. By suppressing hunger

One problem with losing weight is hunger pangs. With constant eating and snacking, our body will not be able to burn all the calories and instead, it is stored in the body as fats. By taking Instant Knockout throughout the day, it will reduce cravings and control your hunger. With less food intake, less fat is stored in the body.

3. By boosting energy levels

Instant Knockout can help the body get enough energy to cope up with an active lifestyle. With an increase in energy, you can exercise more. The stimulants present in this supplement can fuel the body and keep it energized the whole day. Instead of feeling tired, your elevated energy levels can help you to sustain more strenuous workouts.

Is Instant Knockout Safe?

Fat burners are safe to use. Instant Knockout is classified as a thermogenic fat burner that can boost the amounts of calories your body will burn by increasing its metabolic rate. By taking these supplements, the ingredients present in each capsule like cayenne pepper and green tea can increase the body’s core temperature and increase the energy spent.

Instant Knockout has all the natural ingredients needed to increase the metabolic rate without any side effects. When you combine it with a normal diet and an exercise plan, your body can lose fat and gain the necessary muscle mass for a well-toned physique.

Green tea is considered as a fat burner and helps the body lose weight by increasing fat-burning activities. Its main components, caffeine, and catechins are responsible for these actions.

Catechins have antioxidant and antiviral properties that stimulate fat oxidation. Caffeine, on the other hand, increases energy spending and boosts short-term thermogenic effects.

2. Cayenne Pepper

Another effective metabolic booster is cayenne pepper. It increases the internal temperature of the body which in turn can increase the amounts of calories burned.

This is caused by the active compound in chili peppers called capsaicin. It is the same compound that makes peppers spicy or ‘hot.”

This ingredient is a water-soluble fiber that comes from the roots of the Konjac plant. Fibers play a vital role in weight loss because it takes some time to digest.
