Instant Knockout Fat Burner Review

Initial Thoughts:

Love the packaging. There’s a strong association between Instant Knockout and UFC fighters who have used it to cut down pre-weigh in and the packaging reflects this. Considerable effort has gone in to making this look like a professional product and that should reflect well on the actual supplement itself. Let’s face it, if UFC fighters are using it, I think it bodes well for the rest of us.


I am really happy to see that there is no proprietary blend here and that all of the ingredients are listed to provide a whopping 2825.11mg of natural ingredients. So what is in it?Instant-Knockout-Ingredients

Vitamin B6 – Using it in its most natural form, pyridoxine, B6 is an essential nutrient to raising the body’s metabolism and aiding the fat burning process.

Vitamin B12 – B12 fights fatigue, muscle wastage, boosts mood, cognition and is vital to many bodily functions including metabolism and food digestion. So to put it bluntly, we need this for smooth operation and be able to smash those workout sessions which in turn helps you burn fat and lose those unwanted pounds.

Zinc – A study in 2013 showed that people suffering from obesity had low levels of Zinc. Also, if you are deficient in Zinc it means you cannot absorb the nutrients from your food in the intestine.

GTF Chronium –  Research suggests that chromium might improve weight loss in some people who are overweight or obese.

Green Tea Extract – Clinical studies suggest that green tea extract may boost metabolism and help burn fat. One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese. Some researchers think that substances in green tea known as catechins are responsible for the herb’s fat-burning effect.

Green Coffee – Evidence from research has indicated that the consumption of caffeinated coffee can lead to some reductions in long-term weight gain, an effect which is likely to be due to the known thermogenic effects of caffeine intake.

Cayenne Pepper Seeds – The hot and spicy taste of cayenne pepper comes from capsaicin, a compound found in many hot peppers. Capsaicin is known to boost metabolism, causing the body to produce extra heat and burn more calories for fuel.

Glucomannan – This is a soluble, fermentable, and highly viscous dietary fiber derived from the root of the elephant yam or konjac plant, which is native to Asia.  Preliminary evidence suggests that Glucomannan can promote weight loss.

Black Pepper Extract – Black Pepper is a source of piperine, a molecule that does not do much on its own but can inhibit enzymes that would attack other molecules. Due to this, it is ingested alongside some supplements to increase their absorption rates.

Caffeine Anhydrous – The purest form of caffeine available. This compliments the green tea and coffee plus the thermogenic effects of cayenne pepper. It stimulates the central nervous system (CNS), heart, muscles, and the centers that control blood pressure to give you an extra boost and hit that PB.

It is worth noting that the product is manufactured in the USA in FDA and cGMP certified facilities.


Take 4 pills per day; immediately when you wake and then with every meal.  There is a 30 day supply with every bottle. This dosing instruction helps prevent the peaks and troughs of being able to process the ingredients that can be experienced when the doses are scheduled much less. This product is great for both men and women too!


A well researched product with all the right proven ingredients that are there to stimulate energy, increase the thermogenic effects to raise metablolism plus get the nutrients required for normal bodily functions plus an increase in cognitive function for concentration and alertness – that’ll help when you’re doing those overhead dumbbell presses!

For the extra vanity, if you buy more boxes you get a free t-shirt or vest which can make you look and feel like a sponsored athlete! Plus it is kinder on the wallet too as you get an extra box free if you take the 4 box bundle like we did.

There’s a wealth of user testimonials too, and from the likes of the famed Andre Reed and Scott Zolak not to mention the thousands of other people looking to shed those pounds.

There’s a money back guarantee too so a risk free experience.


The best deal is only if you shell out and take the 4 box bundle, if you buy a box per month it is more expensive. It is only available on their website to buy, so not the convenience of Amazon or eBay or even your preferred supplement store.

Gelatine caps are not suitable for vegetarians and there’s a lot of caffeine so get ready to be steaming around all day until you build a bit of a tolerance. It may mean you hold the early morning espresso on your commute to work.

My Review Conclusion:

There’s some really good and well thought out ingredients here, it is a great profile to help stimulate fat burn whilst giving you the required energy and vitamins whilst you pound the treadmill or rowing machine in the gym. The masses of caffeine could be an issue at first but it’s a proven ingredient and will help with the shred.  There is no proprietary blend which gives the consumer the confidence to buy. Admittedly it can work out expensive unless you go for the bundle buying options but I have been using this to help with my summer cut and apart from the initial jitters my abs (where I store all of my body fat) have started to make their presence know, especially around the rib area which was once hidden.

However, don’t just take my word for it, look at the transformation below:


The UFC fighter association and clever packaging has certainly lived up to expectation, I just wish they brought out some other great supplements too.
