Instant Knockout vs PhenQ

Instant Knockout or PhenQ? If you’re looking for the answer to this question, you’re probably comparing these two supplements to one another.

Well, you’re in luck. In this article, we’re going to break down the key things you need to know about both supplements in detail.

Before we get started, we want to make some important points about the supplements in this often-controversial category.

So-called ‘fat burner’ supplements are generally not proven to ‘burn’ fat on their own. Rather, they can provide a range of ingredients such as vitamins, minerals and plant extracts, each of which may (or may not) bring some benefits and support on your health and fitness journey.

It’s widely accepted that the main proven way to lose fat is to stick to a (sensible and well-managed) diet and exercise regimen in which you’re burning slightly more calories than you’re consuming. In other words, it’s about keeping in a slight calorie deficit over time.

There are so many different products out there at the moment and so much conflicting information that it can all become very confusing pretty quickly.

To make matters worse, lots of the supplements in this category have bad reputations, mainly because many of them are marketed as ‘magic pills’ that will work without any effort on your part. If it sounds too good to be true, it usually is.

The aim of this comparison article is to give you a detailed breakdown of both Instant Knockout and PhenQ to bring you everything you need to know about both of them.

So, let’s get down to business and start comparing Instant Knockout and PhenQ to one another.

Editor's note: The writer of this article has not necessarily tried the products featured. All product information provided is purely research based.

Company Reputation and Product Background

Instant Knockout summary:

• Made by UK-based supplements company Roar Ambition
• Uses Green Tea, Cayenne Pepper and Glucomannan
• Contains Caffeine
• Sold directly to consumers from official website

PhenQ summary:

• Made by Wolfson Berg Limited
• Uses Cayenne Pepper, Niacin and Copper
• Contains Caffeine
• Vegan friendly
• Sold directly to consumers from official website

Both Instant Knockout and PhenQ fit into the wider category of health supplements known as so-called ‘fat burners’.

These are products which have been specifically designed to help support you on your journey as you look to get into shape alongside a varied, balanced diet and sensible exercise regimen.

As you can see for yourself, both products have pretty similar aims and purposes. They both contain Caffeine and a range of other ingredients that can each bring a potential benefit to the table.

They both also contain some other commonly used ingredients such as vitamins, minerals and plant extracts.

The Servings

One thing to check on the label of any supplement you’re considering buying is the serving size and frequency.

Each bottle of Instant Knockout contains 120 capsules, which is one month’s supply of four per day.

Each bottle of PhenQ contains 60 tablets, which is a month’s supply of two per day.

You can see for yourself that Instant Knockout comes with double the number of capsules per bottle compared the PhenQ.

With Instant Knockout, you are advised to take four capsules, evenly spaced out throughout the day.

With PhenQ, according to the official website, you are advised to take one capsule with breakfast, and one again with lunch.

For example, you could take one in the morning, one with breakfast, one with lunch and one in the afternoon.

It’s important to note that because of the Caffeine content in both of these supplements, it’s probably best not to consume them within six hours of going to sleep.

The Ingredients and Dosages

Now onto probably the most important section – what exactly is inside each capsule of Instant Knockout and PhenQ?

Editor's note: The health claims about the ingredients mentioned in this article are listed as authorised on the EU Register at the time of publishing.

Here is the full ingredients list of both Instant Knockout and PhenQ in full so you can see for yourself:

Instant Knockout vs PhenQ ingredients

The Instant Knockout (left) vs PhenQ (right) ingredients formulas

Instant Knockout’s top ingredients:

• Caffeine Anhydrous
• Green Tea Extract
• Cayenne Powder
• Green Coffee Bean Extract
• Glucomannan
• Chromium
• Black Pepper Extract

PhenQ’s top ingredients:

• Caffeine Anhydrous
• Copper
• L-Carnitine Tartrate
• Capsimax®
• Chromium
• Niacin

Instant Knockout contains a range of popular ingredients including Caffeine, Glucomannan, some B Vitamins and Green Tea Extract.

PhenQ contains a branded blend called Capsimax®, which includes Capsicum Extract, Niacin Powder and Peperine Extract. PhenQ also contains some other ingredients such as L-Carnitine and Nopal.

Instant Knockout also supplies a dose of the essential trace mineral Chromium, which contributes to normal macronutrient metabolism.

What’s good about both of these products is that they do not use proprietary blends, meaning that the doses of every ingredient on the label are clearly shown, which isn’t the case with all supplements.

Side Effects

Safety is a genuine concern when selecting a supplement in this category.

Firstly, you want to be sure that what you’re taking is legal and that it doesn’t contain any risky or banned ingredients.

We think that it is important that you speak to your doctor or a certified medical professional before thinking about taking a new supplement or making any major lifestyle changes.

You should definitely not take either of these products without first consulting your doctor if you have an underlying medical condition or are taking any prescription medications.

The one thing you should be aware of with these kinds of supplements is that they often contain a lot of caffeine. And you probably already know that too much Caffeine can cause problems and unwanted side effects.

PhenQ includes 142.5mg of Caffeine per tablet, while Instant Knockout contains 75mg of Caffeine per tablet. To put those numbers into context, you’d usually expect to find about 100mg of Caffeine in a strong cup of coffee.

Both of these products contain less than 350mg of caffeine per serving, which should be OK for most people. But we’d recommend not taking either of these products too late in the day – and you should keep tabs on your total Caffeine intake from all sources.

If you are sensitive to stimulants such as Caffeine, then it’s probably best to avoid these products.

Neither of these supplements are intended for use by anyone under the age of 18.


So, that all brings us to the final important aspect of these products – the price.

Instant Knockout is currently priced at $59 / £35 / €45 and you can only buy it from the official website.

PhenQ is on sale on the official website for around $70 / £46 / €66 per bottle, correct as at the time of writing.

It’s worth checking the sites for the latest prices, as they do change from time to time.

As you can see, PhenQ seems to be the pricier option, but they do offer discounts if you buy more than one bottle at a time.

You can also get Instant Knockout more cheaply on a per-bottle basis through the multi-box deals on the official website.

As mentioned above, each bottle of Instant Knockout contains 120 capsules, while PhenQ supplies 60 tablets in each bottle.

Anything Else To Consider?

As we mentioned above, it’s always best to speak to your doctor before thinking about taking a new supplement or making any major lifestyle changes.

Supplements are not intended to replace a varied, balanced diet and healthy overall lifestyle.

It’s always a good idea to ensure that you’re following a good nutrition plan, a sensible exercise regimen, and are getting enough restorative sleep before thinking about trying a supplement.

Conclusion – Our Final Thoughts

So, now that we’ve taken a close look at both of these supplements, let’s summarize what we now know about Instant Knockout and PhenQ.

Instant Knockout:

• Uses Caffeine, Green Tea and Glucomannan
• 75mg of Caffeine per capsule
• Four servings per day


• Uses Caffeine, Cayenne Pepper and Niacin
• 142.5mg of Caffeine per tablet
• Two servings per day

These two popular products are similar in many ways, but they also have a few subtle differences too.

One of the main things to bear in mind is that one bottle of PhenQ contains 60 tablets, in comparison with Instant Knockout that supplies double that amount at 120 capsules.

Overall, these are two popular ‘fat burner’ supplements and there is not much to choose between them. The main differences are some of the ingredients, the dose of Caffeine per tablet, and the number of capsules in each bottle.
