My Instant Knockout Review:

I was sceptical when I first saw Instant Knockout as I know there’s a lot of junk in the world of fat burners. But because the all natural ingredients and their dosages were clearly stated I felt safe to at least have an open mind and give this fat burner a try.

I was totally surprised! After just 2 months of consistently taking this product, my Instant Knockout review found the following:

Enhanced Motivation – It really complimented my workouts and the quality and intensity was noticeably better, I didn’t feel like skipping any sessions.

Better Abs Than Ever Before – The shredding is really evident and it didn’t take long before I saw a significant difference and the drop in body fat percentage feels great.

Sculpted Physique – Muscle mass is more evident alongside the fat loss and I even made some extra gains, due to the extra energy and motivation I was able to increase the weights I was lifting.

Instant Knockout Review of Ingredients

The important part here, they boast about their all natural ingredients, but just what are they?

Instant Knockout Review of Ingredients

Instant Knockout Ingredients Label

Instant Knockout recommend that you take one capsule 4 times daily.

Our advice is that you should be mindful of the caffeine content. Nothing to worry about but if you want to get a good night’s sleep you might not want to take the last capsule too late in the day.

One of the most important factors in regards to the ingredients is that they are specially selected to speed up your metabolism.

This way you store less fat and burn it off faster.

Here are some of the most important ingredients used:

Green Tea Extract

green tea fat burner, instant knockout, best fat burner supplementThat’s right, that thing that people who don’t drink coffee or tea have in the evenings, well there’s a good reason why so many people drink it.

First off, the antioxidant EGCG is proven to activate your metabolism. This encourages your body to use fat as the source of what drives you and as a result burns it off.

Not just good for your metabolism, we like the fact that green tea also helps you to extend your workout by increasing your endurance. This gives you the chance to burn even more calories as part of a longer workout.

500 mg gives you exactly what you need.

Cayenne Pepper Seeds

fat burner, best fat burner, fat burner ingredients, best fat burning ingredients, cayenne pepperGiving your body a thermogenic boost naturally as it raises your body temperature which in turn burns calories because of its spiciness.

Research has also showed that consuming capsaicin (found in cayenne pepper) can naturally suppress your appetite. If you find it hard not to snack in between meals then this could be one of the most vital ingredients for you.

The 100 mg is a great amount once again.


The glucomannan used in Instant Knockout is taken directly from the konjac plant which has a lot of dietary fibre in it. This will put a hold on your appetite, prevent snacking habits and in turn will reduce the amount of unwanted calories you take on.

It swells in your stomach, but before you wonder why you would consume such a thing hear us out – this helps you to feel full as it absorbs liquid, so not only does it get rid of excess water, it stops you from wanting to eat so much and so frequently.

1,800 mg is the dosage and this sits right in the amount required for a maximum effect, whilst still being safe.

Caffeine Anhydrous

This will increase your metabolism, burning fat and turning it into energy. Consumed before exercise it increases the results and feel the effects still after your workout.

This is the highest quality of caffeine (remember – not just any old ingredients make it into Instant Knockout), it also enhances the benefits of some of the other ingredients found in this supplement such as Cayenne Pepper and Green Tea.

At 350 mg this is a safe and optimal dosage to get the true effect.

Vitamin B6

Another ingredient that’s main purpose is to speed up your metabolism (you get the general plan here?). The B6 included in Instant Knockout is pyridoxine, which as well as turning food into energy it also helps the body to absorb protein, enhancing muscle growth.

5 mg is another optimal dosage.

Vitamin B12

Good for energy, it helps your body to turn carbs into glucose which it burns for energy. It has a whole list of other uses too such as helping you to digest your food and promoting muscle growth.

10 mcg is all you need to get the above benefits, and that’s what we have here.

GTF Chromium

Important to compliment the other ingredients contained in Instant Knockout, the small amount of Chromium helps to regulate blood sugar levels and gives you a more balanced energy level.

It can stop your cravings for snacks and control your overall appetite and is often found in a whole host of foods such as fruit and vegetables, seafood, meats and spices.

The 100 mcg included in Instant Knockout is an optimal dosage once again.


Also found in TestoFuel because of its use for ensuring the body has a healthy amount of testosterone.

It has been proven to improve glucose metabolism and fat levels in the blood. Having low levels of zinc gives you a higher risk of having excess body fat.

10 mg is another great boost and well within the safe amount you need.


Often known to you and me as one of the elements of black pepper that gives it its taste, it is useful to those looking to shed some pounds as it stops fat cells from forming. So, a lot of the ingredients are good for your current fat cells, piperine is good for stopping your body producing new ones.

Green Coffee Extract

No, they are not an alien form of coffee, it is just coffee before it has been roasted and is coffee in its most raw and beneficial state.

It is high in chlorogenic acid, good for cutting down any glucose in your liver that might take form otherwise. This is also good for lowering cholesterol levels in the body.

At 100 mg, this will give you everything you need.

Instant Knockout Side Effects?

No Side Effects
With all the ingredients being natural, it contains only safe ingredients and therefore taken as part of a healthy diet there are no known side effects.

The caffeine content is within the daily recommended allowance, but you should think twice against using it alongside other products that contain caffeine.

If necessary, we suggest building up your tolerance to the caffeine with a couple of capsules a day first for a little while before increasing to 4 capsules per day.

Instant Knockout Review Conclusion

Instant Knockout review results

So, we have made it clear in our Instant Knockout review that we love this fat burner!

Although, at our emphasis is on eating clean and training mean to achieve your results, there’s absolutely no shame in taking an all natural fat burner like Instant Knockout to speed up your weight loss and start seeing that muscle definition.

So many inferior products out there will claim their many benefits but either hide the dosages behind proprietary blends or simply don’t include scientifically proven fat burning ingredients. This is because they don’t actually care about you and are trying to make their profit margins as high as possible.

We found Instant Knockout to be amongst the best supplements we’ve come across for fat burning.

One of the most noticeable effects it had was to suppress hunger. Where there would usually be a real hunger coming on between meals, this disappeared after a few days of using Instant Knockout.

The fat burning properties were evident as well, a real fast track to getting abs that really show as one of the clearest places you lose fat is around the waist.

There is a 90-day money back guarantee, but to qualify for this you must purchase 3 months worth of the product so always read the Terms & Conditions.

If you are looking for a product that compliments the hard work you put into the gym, but gives you that extra bit of help burning excess fat, then there isn’t a better product on the market than Instant Knockout.
