What Is Instant Knockout?

Instant Knockout is a famous weight-loss pill created for boxers and MMA fighters.

It boosts the metabolism, burns fat, and suppresses hunger. Currently, it is one of the most effective weight loss supplements for men on the market.

Natural components and plant extracts are used in the product to help the capsules replicate the thermogenic effects of certain prescription drugs commonly used for weight loss.

What Is PhenQ?

Another fat-loss drug that we will be discussing in this review is PhenQ. This pill isn’t your typical weight-loss product. Unlike other supplements, it has several different approaches to help you lose weight and keep it off.

It works to decrease hunger, increase energy levels, reduce body fat, and prevent fat from accumulating again.

The company created it by conducting research on a wide range of plant extracts, minerals, and nutrients and then creating the best fat loss product based on the findings.

PhenQ’s weight loss capsule comprises six natural ingredients that have been proven to be safe and effective for people hoping to reduce their weight.

Ingredients Comparison

In the section below, we’ll take a closer look at the ingredients in both these weight loss products.

Instant Knockout Ingredients

Here are some of the key ingredients in Instant Knockout that aid weight loss:

Green Tea Extract

Green tea is a popular weight-loss beverage that contains a variety of antioxidants, the most important of which are catechins.

These chemicals can help regulate your weight by increasing your metabolism, inhibiting fat absorption, and reducing the free radicals in your body.

Vitamin B6

Vitamin B6 aids in the reduction of BMI and muscle mass composition.

According to one study, women who took vitamin B6 supplements lost more weight, had slimmer leg muscles, and had a lower waist-to-hip ratio.

Besides its fat-burning properties, vitamin B6 has a role in over 160 processes in the body, such as how our bodies regulate blood glucose levels, which in turn affects weight gain. It also has a role in fat metabolism.

Capsicum Extract

Like PhenQ, Instant Knockout also contains capsicum extract that offers a number of fat-burning benefits.


Piperine, a chemical found in black pepper, also has thermogenic qualities. This means that it boosts your body temperature and aids fat burning.

On top of that, it has a number of other advantages. It may help prevent the formation of new fat cells and aids in the regulation of a condition known as obesity-induced dyslipidemia, which involves high levels of fat in the blood.


Caffeine can improve focus and endurance, and anhydrous caffeine has a significantly greater impact on athletic performance than the caffeine found in tea or coffee.

This form of caffeine will reduce your hunger, raise your metabolic rate, and increase your energy levels when you work out.


Like any good dietary supplement provider, PhenQ offers a detailed list of ingredients. Here’s a detailed list of the most prominent natural ingredients found in this supplement:

Capsicum Extract

Capsicum extract is derived from a range of peppers. It has thermogenic properties, which increase body heat and provide various benefits, including antioxidant and anti-cancer properties.

The major effect that it has on weight loss is to speed up the rate at which the body metabolizes fat and performs other metabolic activities.

Vitamin B3

Vitamin B3, commonly known as Niacin, helps your body burn calories to produce energy rather than storing it as fat.

This impact is enhanced when you exercise, so even going for a stroll can assist in raising the effect of vitamin B3, allowing you to lose weight more effectively.

Chromium Picolinate

Chromium Picolinate, a mineral present in various foods, can help you reduce your craving for sugar and carbs, which allows you to manage your blood sugar levels effectively.

It accomplishes this by enhancing sugar uptake at a cellular level, which, in turn, reduces your cravings.


Like Instant Knockout, PhenQ also contains piperine, a compound with thermogenic properties that aid weight loss.


Caffeine is a chemical commonly found in coffee. PhenQ has a lower concentration of caffeine than Instant Knockout, so it is suitable for use if you are particularly sensitive to the compound.

It aids weight loss by increasing your body’s metabolic rate, which means you’ll burn calories faster.

Calcium Carbonate

Calcium carbonate is a chemical messenger beneficial for maintaining good bone health.

The compound notifies the brain that the body currently contains too much fat and that it needs to start burning it.

Ingredients Verdict

Both Instant Knockout and PhenQ live up to their claims regarding including all-natural ingredients in the formulation of their products. We found that these supplements shared the following common ingredients:

  • Caffeine
  • Piperine
  • Capsicum extract

However, Instant Knockout contains a higher concentration of caffeine, which will work well for active people. PhenQ serves as an excellent alternative for those who aren’t as active as athletes but still want to enjoy weight loss benefits.

We were happy to find that all the ingredients found in these supplements were backed by a number of studies.
