What Are The Instant Knockout Ingredients?


Instant Knockout fat burning supplement is formulated using ten powerful and natural ingredients that have been scientifically selected because of their benefits.

Cayenne Pepper Seeds

Cayenne pepper seeds have become a trend for individuals trying to lose weight in recent years. It contains capsaicin, which is a powerful and active compound in chili peppers that helps promote metabolic and vascular health. It lifts the body’s metabolism and improves how it stores carbohydrates, which ultimately accelerates the fat-burning process.

Green Tea Extract

The benefits of green tea are well documented. It contains high amounts of catechins, a natural antioxidant. It also contains caffeine, which helps increases one’s focus and mental awareness, according to the National Center for Complementary and Integrative Health.


Glucomannan is a natural dietary fiber extracted from the roots of the Konjac plant. The way this ingredient works is to go through the stomach without needing to be digested and absorbing water, which helps promote satiety for longer, reduce cravings, and suppress appetite. Glucomannan helps promote cholesterol balance as well.

Green Coffee Bean

The green coffee bean is basically coffee beans that haven’t been roasted. This coffee doesn’t contain any caffeine, but it is rich in chlorogenic acid, which helps slow down the body’s fat absorption process and suppress sugar cravings.


Piperine is a compound extracted from black pepper, which boosts metabolism, slows down fat cell formation in the body, and helps improve digestion.

“I would say Instant Knockout gave me the most energy throughout the day, without feeling the jitters like the other products and giving me enough energy to workout at the end of my day.”

But in some cases, like Sharon Addison, she reported experiencing hives. According to her, it might have been a result of a secret ingredient in the product as she researched it before purchasing.

“Upon taking the first recommended dose, I broke out in hives. I tried it again the next day and again broke out. I have always taken the ingredients included in this product–so this led me to believe that there is an element unknown included in this product.”
