Safe, Natural and Effective Ingredients

Instant Knockout was designed with one thing in mind – safe fat burning. It contains only natural ingredients - we don’t use synthetic or lab-made nutrients, meaning you can be sure you’re getting only the best supplement available.

Each active ingredient is clinically dosed to make sure you get all of the benefits, without the side effects. So if you’re concerned that Instant Knockout might contain harmful ingredients or dangerously high stimulant levels, don’t be.

We've committed hours and hours of research into formulating the very best for you. You won’t get side effects and you won’t feel ‘wired and tired’ either. What you will find though is targeted focus and motivation, allowing you to channel all of your energy into PR-busting workouts.

The core ingredients

Green Tea Extract

Green Tea Extract

Speeds up your metabolism and boost fat oxidation.

This powerhouse nutrient fights fat from different angles, making it an essential Instant Knockout nutrient.

Studies show that green tea can elevate your metabolic rate and calorie burn via a process of thermogenesis, helping you to tap into stored fat[1]. It ramps up fat burning by over 15% and gives you a much needed kick of energy – even when you’re in a calorie deficit.

Cayenne Pepper Seeds

Turbo charges your metabolism naturally.

This nutrient-packed spice contains capsaicin – a bioactive compound known for its fat burning ability.

Much like green tea, capsaicin is a potent thermogenic. It raises your metabolism and triggers the switch for enhanced fat oxidation.

You’ll increase your daily energy expenditure by burning more calories, and your insulin sensitivity will go up by as much as 24%[2], leading to more efficient energy storage.

Suppresses your appetite to reduces cravings.

Glucomannan is a dietary fiber that reduces appetite and food cravings by helping you feel fuller for longer.

As a soluble fiber with a long-chain, complex carbohydrate structure, it boosts weight loss by helping you avoid the triggers of over-eating and excessive snacking.

Current research suggests that glucomannan could be the key to weight-related, metabolic health issues in the US[3].
