Instant Knockout vs AtraFen Elite

Todays Instant Knockout vs AtraFen Elite review has us looking at two of the markets bigger brands.

Instant Knockout has the backing of a big online following, something they clearly put a lot of effort into achieving. On the other hand, AtraFen Elite has proven to be a big seller on Amazon.

Which of these deserves their lofty status in the market? We are going to see which is the better option and determine whether either is a product worth purchasing.

In order to impress, they need to do the following:

  • Burn fat effectively
  • Be safe
  • Suppress appetite
  • Increase energy

Anything less than this won’t be good enough, so let’s see what they have in store.

Instant Knockout vs AtraFen Elite: Who Makes These Fat Burners?

Roar AmbitionInstant Knockout Review

This is the UK based company behind Instant Knockout.

They ship directly from both the UK and the USA and make everything to FDA and GMP approval. Roar Ambition check and amend their ingredient profiles regularly. This means the customer is getting the best possible version of their product at all times.

There are also a lot of Instant Knockout before and after profiles on the net. Clearly, people are happy with their results.

When purchasing a supplement, it should be risk-free. This is the case with their products as they offer generous money back guarantees.

In terms of endorsements, theirs are pretty impressive. UFC fighter Diego Sanchez puts his name to this product, he uses it to make weight before a bout.

Roar Ambition also makes a T booster called TestoFuel. This is endorsed by former Mr. Universe Robby Robinson.

NutratechAtraFen Elite

This is the US-based company behind our second product.

They have a 30-day money back guarantee which is good to see.

With a range of products available that include cleanse and probiotic supplements and nootropics, they have a good amount to choose from.

Nutratech has a standard version of this fat burner which they say helped women to lose an average of 11-13 pounds during their first 30 days of use. Impressive stuff but the ingredients and dosages need to be examined before we can get too excited.

We don’t see the amount of AtraFen Elite before and after profiles to match Instant Knockout but maybe they haven’t had the exposure as of yet.

This is a product that sells well on Amazon so they are doing something right. Time to see if this all results in two good products.

Instant Knockout vs AtraFen Elite Ingredients

Now we can really see which of these is a better fat burner.

The early signs for AtraFen Elite aren’t great though. They use one big proprietary blend that covers all ingredients. They only give the overall dosage of all ingredients combined meaning we cannot see how much of each one is included.

Also, their suggested serving means you only take it twice a day. This means the fat burning benefits aren’t going to be spread out as much as the one capsule 3-4 times a day from Instant Knockout.

Mutual Ingredients


This is the only mutual ingredient included. AtraFen Elites version just says Caffeine, but Instant Knockout have gone for Caffeine Anhydrous which is a powdered form that is easily and quickly absorbed by the body.

Caffeine is a great fat burner though which is why we see it so often.

The energy boost is, of course, a great place to begin. Anyone using a fat burner alongside a diet that restricts calories, or just needs more energy in the gym is going to benefit here.

It has also been shown to get your metabolism moving and enhance focus. The 350 mg split across 3-4 servings in Instant Knockout is a good amount.

The fact that it is in the proprietary blend of AtraFen Elite is always a bit of a worry.

Individual Ingredients

Instant Knockout

Green Coffee Bean Extract

A great fat burning ingredient.

It is basically coffee before the color and chlorogenic acid has been roasted out. This is an acid that is most beneficial for fat loss.

It stops us from storing as much fat and gets blood sugar levels under control.

WebMD advise of a study that looked into adults with obesity. This found that taking Green Coffee Extract for between 8 to 12 weeks meant more weight loss for those when compared to others taking a placebo.

A good ingredient to get you burning fat and the 100 mg in Instant Knockout is a good amount.

Vitamin B6

Another useful fat burner here.

B6 is similar to other B-vitamins in that it plays a role in how our bodies create energy from food sources. It converts this into glucose which is then used as energy.

B6 also has links to boosting metabolism and the 5 mg included is another good dosage.

Vitamin B12

B12 is important as it can help prevent your body from storing as much fat so it is a very useful ingredient.

Our bodies can’t actually create our own so supplementing it is a good idea. This is even more important for vegetarians and vegans as prominent sources are meat, fish, and dairy.

B12 will also promote red cell production meaning it will battle fatigue as well.

Green Tea Extract

Among the best in the business for natural fat burning.

It has two of our favorite fat burning traits.

Firstly, it is a thermogenic. This means it will have your body burning fat even as you rest. It heats the body on the inside, causing it to burn fat to cool itself down.

The catechins are really beneficial here. says that they are anti-obesity as well as anti-diabetic.

Green Tea Extract has also been shown to enhance endurance levels which is good news for the gym.

WebMD tells us that Green Tea is a milder stimulant than the likes of Caffeine Anhydrous and it contains 2-4% Caffeine. It might be milder, but it will also provide a boost to your thinking and alertness.

The dosage of 500 mg is an optimal dosage that will really give you the above.

Cayenne Pepper

Another great fat burner.

Also, another thermogenic which is good to see. Cayenne Pepper has also been found to work as an appetite suppressant.

WebMD supports this and says it has been found to curve appetite, especially in those who do not already eat spicy foods.

The 100 mg included is another great dosage from Instant Knockout.


A famous T booster ingredient but why is it good in a fat burner?

It stops us from storing as much fat which is always good but it also has links to glucose metabolism.

Eating fewer carbs? says that Zinc has also been shown to improve mood.

With 10 mg included, it is yet another optimal dosage.


Chromium is another useful fat burner ingredient as WebMD advise that it can decrease LDL (bad cholesterol) levels in people who have lower blood fat levels.

There are even links to it being able to communicate with the brain to tell it that the body is full.


Instant Knockout really is giving us the best fat burning ingredients around.

Here we have another appetite suppressant. This is a dietary fiber that absorbs water and swells in the stomach. This makes the user feel full.

This is also what will stop you from snacking in between meals.

With 500 mg included, it is another big dosage.

Black Pepper Extract

A good ingredient but not a direct fat burner.

Still, it is useful because it enhances the capabilities of the other ingredients.

This means the fat burners, appetite suppressants, thermogenics etc will be even more useful.

AtraFen Elite


An ingredient often found in energy drinks but not the most impressive. say that it is a common ingredient but there is a surprisingly minimal amount of research behind it.

They also advise that there is no significant contribution towards energy though. It is quickly absorbed but broken down and not as effective as you would hope.

The support for its blood flow enhancing capabilities don’t have a large amount of backing and there don’t appear to be any benefits for fat burning.

Not a great start for them.

Synephrine Caprylate

A bad ingredient, at least the last one was safe, this might not be!

Synephrine is a banned substance with many sporting organizations and is a controversial ingredient. The potential side effects should worry you and these are more common when combined with Caffeine, as this supplement does.

Often known as Bitter Orange the main problem here is that it is in a proprietary blend so we have no idea how much we are getting.

WebMD advise that it can be unsafe when taken as a weight loss supplement. The potential side effects include burning, dizziness, stinging, blurred vision, drowsiness and more.

If you are part of a sports team or are the subject of testing then check with your sporting organization’s rules before consuming.


For a product that sells so well on Amazon, it is yet to get going.

At least this ingredient is safe to consume. describe it as an important molecule in the brain with limited supplemental usage due to it being rapidly broken down into active components.

Seemingly, a pointless ingredient.

It is linked to improving mood but like we are seeing with most of the other ingredients this isn’t what we after.

Nettle Leaf Extract

A potentially good ingredient this makes for a welcomed change.

It has been found to lower blood sugar and increase metabolism which is good for fat burning. Its potency isn’t the best but it is a popular drink in the form of Nettle Tea where it has links to fat loss.

The dosage isn’t given here so we don’t know how effective it can be.

Yohimbine Extract

Another ingredient to look out for, and once again – not in a good way!

It does have some support as a fat burner, it can be an appetite suppressant and help us to break down fats. But is it worth the risk?

WebMD says that when taking orally is possibly unsafe. WebMD also advises that Yohimbine has been linked to reports of severe side effects that include heart attacks and seizures, sleep issues, irritability, irregular heartbeat and more.

Notably, it is illegal to sell the man-made yohimbine hydrochloride variant as a dietary supplement in the US.

Of course, the more there is, the bigger the concern but we have no idea how much there is in this supplement because of the proprietary blend.

Inositol Niacinate

It’s not a good sign when you are relieved to see safe ingredients!

PubChem says that it is used in food supplements as a source of Niacin (Vitamin B3). They also comment that it plays an essential role in the metabolic process which would be of use here.

It can help to produce energy which is good for the fat burning of course.

Still, we don’t have the dosage information which would help.

Instant Knockout vs AtraFen Elite Side Effects

It is easier to start with Instant Knockout since there is no risk of side effects when using their product. It is full of safe and natural ingredients that are dosed well.

AtraFen Elite is a different story though.

Their inclusion of Synephrine and Yohimbine puts you at risk of potential side effects including burning, dizziness, stinging, blurred vision, drowsiness among others for Synephrine.

Also, Yohimbine is linked to causing seizures, heart attacks, as well as sleep issues, irritability, irregular heartbeat and more.
