Instant Knockout vs Ab Igniter Black

Top fat burners are hard to come by. Our Instant Knockout vs Ab Igniter Black review today will compare two of the industry’s bigger brands.

But in this industry, the bigger brands don’t always mean better products.

For a supplement to work it has to use proven ingredients and the dosages are vital as well.

With Instant Knockout, we have a product with a seriously loyal following. You hear a lot of noise surrounding this supplement. Then there is Ab Igniter Black, it sells well on Amazon so it has caught our attention.

In order for either product to impress they need to do the following well:

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

Anything less than this won’t suffice so let’s see which is the better product.

Firstly, we will get to know the brands a little better.

Instant Knockout vs Ab Igniter Black: Who Makes These Fat Burners?

Roar AmbitionInstant Knockout Review

This is the team behind Instant Knockout.

Based in the UK there is always a lot of positivity surrounding their brand. You will find that a lot of people take to the net to post their before and after pictures.

They really do customer service the right way. They review and amend their ingredients and dosages frequently ensuring their customers get the best possible version at all times.

With a generous money back guarantee there is a lot to like.

Roar Ambition has some impressive endorsements as well. UFC fighter Diego Sanchez puts his name to this product. He uses it to make weight before a bout.

They also make a T-Booster called TestoFuel. Former Mr. Universe Robby Robinson puts his name to that product.

Top Secret NutritionAb Igniter Black

This brand was actually acquired in 2017 by Hi-Tech Pharmaceuticals.

You can’t get a lot of information about Top Secret (oh the irony!) but we have read some reports that they make high-quality products that provide maximum benefits to its users. This is through a site that sells their products directly which explains why the statement is so generic!

Hi-Tech Pharmaceuticals though have been around since 1994. It isn’t much of a surprise that they are acquiring various brands. You will find that they have a wide reach with many products being sold in store around the world.

Their operation is big with a massive 600,000 sq ft warehouse!

The Top Secret website now just takes you to GoDaddy where you can actually buy the domain. Either someone’s made a mistake or they are just letting this go.

Like we mentioned it is one of the most popular fat burners of Amazon. Let’s see if this is deserved.

Instant Knockout vs Ab Igniter Black Ingredients

This is where we can really set these two apart.

The early signs aren’t great for Ab Igniter Black. By using a proprietary blend they are not giving us access to some of the dosages. This makes it difficult to see if the doses will be effective but we still have a lot to go on.

The serving suggestions definitely favor Instant Knockout. They advise taking one capsule 3-4 times a day to spread out the benefits. Ab Igniter Black say 2 capsules before the biggest meal of the day. This doesn’t spread the benefits out and will wear off.

Mutual Ingredients

Caffeine Anhydrous

Always a useful ingredient in a fat burner.

Anhydrous refers to the fact that this is a powdered form making it easily absorbed.

It will really boost your metabolism that will get the heartbeat going and have your body burning fat.

You will also welcome the added energy boost if you are using a fat burner alongside a diet that allows fewer calories than usual.

Some even believe it helps the user to focus. Good news for the gym then.

The 350 mg that will be spread across 4 servings in Instant Knockout is a sensible amount. The 300 mg in one go from Ab Igniter might be a bit too much for some. It is always good to build your tolerance up if you think this will affect you.

Good that it isn’t in a proprietary blend from Ab Igniter at least.

Cayenne Pepper

A very clever inclusion from both. Instant Knockout has gone for Cayenne Pepper here and Ab Igniter Black have included Dihydrocapsiate which is a form of hot pepper.

It has many uses and is a popular ingredient in a fat burner.

This is because it is a proven thermogenic. This means it will heat the body up on the inside, causing it to burn fat to cool itself down. Usually one of the most effective ingredients for this.

It even works as an appetite suppressant. This means it swells in the stomach, causing the user to feel fuller for longer periods. A great trait in that it should stop you from reaching for a snack in-between meals. Helping you to keep fat supplies away.

Supplementing this ingredient is a good way of getting the benefits without getting the heat.

It is also thought to encourage the body to use fat for energy instead of carbs. This fat oxidation is a great way of ridding your body of the unwanted fat reserves that are hard to shift.

At 100 mg, Instant Knockout have included a useful amount. There is just 43.5 mg in Ab Igniter which could help but not in the same way.

Black Pepper Extract

A popular ingredient for supplements yet one that does not directly burn fat.

Still, it earns its place by enhancing the capabilities in the other ingredients.

This means it is only good if the other nutrients are as well. As we go through the rest of the ingredients you can see for yourself but the dosage in Instant Knockout is more committed as they have gone for 10 mg. Ab Igniter Black 3 mg.

Individual Ingredients

Instant Knockout

Vitamin B6

An effective ingredient once again.

Like a lot of B vitamins, it helps the body to burn fat by turning them into glucose and using them for energy.

Making a use out of the things you don’t want is great and it can even enhance the muscle to make them more effective during a training session.

Targeting carbs ensure they are used and don’t find their way to places you don’t want them showing on your body.

At 5 mg they have gone for a very good amount as well.

Vitamin B12

Another that stops you from storing fat it will increase energy levels as well.

B12 isn’t something we can create naturally so maintaining levels through supplementation can really benefit the body.

You will find it in meat, fish, and dairy making it a good ingredient for vegetarians and vegans to get hold of.

By promoting red cell production it ensures you do not feel fatigued.

At 10 mcg you are getting another optimal amount.


Low levels in the body put you at risk of having excess body fat.

Zinc has been found to improve glucose metabolism and fat levels in the bloodstream.

Supplementing it is a good idea as many people do not get enough of it. It is also great for testosterone boosting as our bodies cannot create more without Zinc. describe it as an essential Vitamin and it has even been found to improve your mood.

The 10 mg included will really raise Zinc levels.


Another effective ingredient this one improves insulin resistance.

It contains various trace elements and can regulate blood glucose.

WebMD advise that it can decrease LDL or bad cholesterol levels in people with slightly high cholesterol levels. It has also been found to lower blood fat levels.

Found in the likes of vegetables, seafood, fruit and meats it is a useful ingredient.

There are studies that say it can help with communicating with the brain to control appetite.

With 100 mcg, Instant Knockout have gone for another excellent dosage.

Green Tea Extract

Up there with the best and so much more than a popular drink.

When you think of thermogenic ingredients Green Tea often comes to mind. It is another that will get your body burning fat even when you are resting.

Add stamina and endurance to the list of positive traits and it is one of the best ingredients in this whole Instant Knockout vs Ab Igniter Black comparison.

Instant Knockout has once again got their dosage right. Including a big and effective 500 mg.

Green Coffee Extract

Just coffee before the color has been roasted out of it.

The chlorogenic acid in this ingredient is what is most beneficial. It can stop you from absorbing fat and has been shown to reduce blood sugar.

WebMD advises that one study found adults with obesity who took Green Coffee Extract for between 8 to 12 weeks lost more weight than those taking a placebo.

Another useful ingredient and 100 mg is a good dosage.


Another appetite suppressant and another effective one. This dietary fiber is another that swells in the stomach to make you feel full.

More opportunities to prevent yourself from putting fat back on after you have burned it off.

Another great dosage at 500 mg.

Ab Igniter Black

A good ingredient but we are getting a lot of stimulants already.


A useful ingredient but we are wary of the stimulant content already now.

It will raise heart rate but is thought to have a milder feel than Caffeine. It does stop the user from retaining water as much. says that it contains more caffeine than coffee beans.

A popular ingredient in soft drinks WebMD tells us that it can be unsafe to take in large doses over a long time. They comment that it can be unsafe when taken in doses over 250 – 300 mg.

It is part of the energy blend in Ab Igniter Black. The blend totals 800 mg with Caffeine Anhydrous taking up 300 mg of that. The only other ingredient is Guarana making the dosage 500 mg.

WebMD has a few words of caution and they say that larger doses could cause a headache, agitation, anxiety, pain when urinating, ringing in the ears, stomach cramps and irregular heartbeats.

Not a risk we would like to take.

Siamese Ginger

A traditional fat ingredient and one that acts as a thermogenic. We are all up for this and it is one of the more natural feeling ingredients.

It can inhibit fat storing through our food and break down fats that are already stored., says that when taken with a meal Ginger can slightly but significantly reduce the sensation of hunger and subsequent caloric intake.

The proprietary blend causes a problem here since the dosage is not revealed.

Huperzine A

Not the most common fat burning ingredient.

You are most likely to see it in a nootropic or even a pre-workout as it has cognitive capabilities that can help you to concentrate in the gym.

Making you more alert it might get you off your phone and can enhance muscle strength.

With no dosage revealed we have no idea if it will work anyway.


An underwhelming ingredient that says is high in phenolics and maybe antidepressant and antidiabetic but there are no human studies to support this.

With no human trials, it is a difficult ingredient to get behind.

There have been some fat burning properties have been noted with the whole plant, but these are not overly remarkable according to Examine once again.


The worst ingredient in the whole review.

The potential side effects of using this ingredient are enough to put us off.

Sure it might be an appetite suppressant and even speed up the way we break down fat but as WebMD advise Yohimbe products that contain man-made yohimbine hydrochloride as an ingredient are not legal to sell as a dietary supplement in the US.

Larger doses or taking it over longer periods can lead to more serious side effects but most commonly people have been found to experience elevated heart rate, sleep issues, raised blood pressure, irritability, irregular heartbeat as well as others.

One to avoid.

Instant Knockout vs Ab Igniter Black Side Effects

Instant Knockout uses all natural and safe ingredients that are well dosed.

The same cannot be said for Ab Igniter Black though.

The 800 mg of stimulants is a concern alone and can lead to insomnia, stomach irritation, increased heart rate, nausea and vomiting among other things.

We also have Yohimbine to worry about. This can cause raised blood pressure, irritability, elevated heart rate, sleep issues, irregular heartbeat as well as others.
