Instant Knockout and Grenade are two separate brands that reign in popularity as fat burner supplements within the health and weight loss market.
Many of you may be interested in how these two products fare against one another, in terms of active ingredients, value for money, and versatility within everyday life.
Within this Instant Knockout vs Grenade review, all the in-depth details about the products themselves will be explored, and I will break down the key components which these supplements are unique for in the market at the moment.
Of course, each of the supplements will have their own series of pros and cons, but it is really important to evaluate these top competing fat burners against one another, to come to a conclusion of which of them is superior. These are things that you deserve to know, before spending your cash on them, right? Let’s begin shall we?
Instant Knockout vs Grenade Thermo Detonator: Introduction
Grenade Thermo Detonator is an award winning and internationally renowned fat burner supplement and energy booster. The formula has been critically created by nutritional leading experts (in 2010), who have integrated together essential active ingredients that are known to aid those seeking out to lose weight and keep the pounds off.
The formula itself is suitable for both genders, and over the years it has managed to gain huge attraction from fitness enthusiasts and body competing athletes that are looking to be the most chiselled and lean version of themselves.
Today, Grenade Thermo Detonator actually has a spot for being one of the most bought fat burning supplements out there, and over 100 countries have purchased this product in great numbers. A reason for its growing popularity lies with Grenade’s clever marketing influence and general endorsement outreach to some of the worlds best endurance athletes.
Instant Knockout on the other hand has carefully selected its ingredients over many years of research. Their 10-ingredients formula has been constantly upgraded and reinvented, with data and research results that support the formula’s efficacy. Instant Knockout takes pride in their highest quality and assortment of their ingredient list. However the question remains, how good is it, when compared with Grenade?
Which fat burner is the best?
This will all depend on the goals and expectations that you have when using these supplements. For example, consumers that use each of these supplements will be focused on the quality of the ingredients list, its aid to their weight loss journey, or the possible additional energy boost that supplements like these provide. Even aspects of costing weigh-in hugely for the value and versatility that a supplement’s role can have within the consumers’ everyday lives. Therefore it does not just come down to the dosage effects that Grenade and Instant Knockout provide. It’s a whole picture that needs to be accounted for.
However, to understand what fat burner is the best, take a look at the fat burner candidates down below; including their individual ingredients and mechanisms of action.
Instant Knockout vs Grenade: The ingredients
Instant Knockout’s main ingredients
So to begin with, Instant Knockout’s main ingredients list and active compounds are as follows:
- Green Tea
- Cayenne Pepper
- Green Coffee Bean Extract
- Vitamins B6/B12 (pyridoxine HCL and cyanocobalamin)
- Chromium (picolinate)
Grenade’s Main Ingredients
Grenade’s main ingredients list and active compounds are as follows:
- Green Tea
- Cayenne Pepper
- Bitter Orange Powder
- Raspberry Ketones
- Green Coffee Bean Extract
As you can most likely see, both of the best fat burner supplements on the market have very similar crossovers when it comes to the key ingredients used. Both Instant Knockout and Grenade utilise the active ingredients of green tea, cayenne pepper, caffeine and green coffee extracts. These are the most common uses of ingredients within weight loss supplements as research has proven their effectiveness and safety when used in the minimum recommended amounts advised by nutritionists (which both do).
FYI– Healthy adults should consume no more than 400 mg of caffeine, which is equivalent to 4 regular cups of coffee. Instant Knockout uses 75mg, whereas Grenade uses 112.5mg of Caffeine per capsule. This is very much still in the means of dietary aims and therefore can be administered safely and responsibly within every day diets.
The main differences that are very apparent between the two supplements and their ingredients, is Bitter Orange Powder and Phenylalanine, which is not present within Instant Knockout. However, Instant Knockout uses Glucomannan, in addition to the essential minerals and vitamins- which come across as an extra attention to detail. Especially due to the fact that the Instant Knockout Glucomannan gives consumers a good dose of their necessary dietary fibre that they need daily.
Direction of dosage and quality of main active ingredients- Instant Knockout
The Chromium is in doses of 100 mcg within this supplement. For those that are not aware, chromium is a trace mineral that has been known to aid in the body’s insulin resistance management, and improvement of overall glucose levels. Improving insulin resistance is key to effective weight loss, and insulin has been known to massively contribute to the increase of hunger and cravings unnecessarily. 
Green Tea Extract
Green Tea Extract has been known to stimulate the body temperature which helps to boost metabolism rates of those that consume it. The active ingredient within the Green Tea Extract is EGCG, which has clinically been proven to aid weight loss with a unique mechanism of burning fat .  There are even noted cases where neurological function have been observed within clinical studies, as EGCG happened to have aided brain cell decline in older age groups, in addition to giving consumers increased bursts of energy. 
Cayenne Pepper is a substance that can be an effective fat burner due to its thermodynamic abilities. Just like Green Tea, it stimulates the metabolism to work harder and burn more calories overall.
Glucomannan is a fibre rich substance that is derived from all-natural ingredients. Coming from the Konjac plant, it has been medicinally used for centuries. Today it is relied upon as an appetite suppressant, weight loss aid and blood sugar levels management. How, you ask? It is simple. Once absorbed, this herb becomes of a gel-like nature within the gut and digests slowly. Keeping you fuller for longer. Most fat burners rely heavily on this for appetite control, as it is seen as magic!
Direction of Dosage and quality of main active ingredients- Grenade
Green Coffee Bean Extract
This is a well-known ingredient within fat burners, and helps with the goal of fat loss. Just like caffeine, it comes from coffee beans. However the active compound here is the chlorogenic acid which is attained by not roasting the coffee beans. This acid is known to have antioxidant effects, lowers blood pressure and helps you lose weight. Having this is more potent than taking caffeine for the strive to burn fat. 
Capsicum is the substance that is responsible for the chilli sensation when you eat hot peppers. This supplement in the right dosages can aid weight loss by speeding up your metabolism overall. It’s active mechanism within the body once consumed, increases oxygen consumption and therefore changes the body’s temperature. So, to maintain homeostasis your body works harder too in doing so, meaning there will be an increase in the calories expended. 
Yerba Mate is another significant herbal supplement that many of the other fat burners on the market tend to use. Due to it being so rich in multiple antioxidants (polyphenols, saponins, caffeoyl etc.) it can strengthen the immune system and central nervous system, as well as improving your mental focus/energy levels. Even though calorie deficits are usually the only way to significantly lose weight, this should help give you a boost of exactly what you need to get through your workout routine, and fitness journey. It can be tough otherwise, when cutting out the calories.
Bitter Orange Powder
Bitter Orange Powder is also known as Synephrine. It is massively effective at increasing resting metabolic rate, meaning you can burn fat all day, with increased energy levels.
Directions of use
Of course, it is always really important to check the directions of use before purchasing any supplement, and be aware of any warnings or reactions that the active indigents may incur when consuming.
In regard to Instant Knockout, one bottle contains 120 capsules, meaning you have a 30-day supply per pack. To take the correct dosage, it is advised to take one capsule four-times a day, with a glass of water to swallow the capsule comfortably. You can find the directions of use clearly stated just above the nutrition label.
Grenade is very similar to Instant Knockout in terms of its administration procedure, however the only difference is, it advises consumers to take it prior to their main meals, and on an empty stomach (30-minutes before).
Quality of ingredients and dosage: Instant Knockout
In order to pick a winner between Instant Knockout vs Grenade, it is important to address that both ingredient profiles are really great in boosting the metabolism. However Instant Knockout overall is so much more efficient in achieving that, without the long list of stimulants that Grenade chooses to add. Instant Knockout is more holistic and natural, and has higher dosages in its key active ingredients. Grenade crams way too much with a risk of under-dosing the components that are needed to perform at maximum potency.
Are there any side effects for Instant Knockout and Grenade?
The only side effects that may be worth considering here is the high doses of caffeine within the Grenade supplements. While they both keep to their daily recommendations, if you are a coffee lover, you are at risk of exceeding your daily dosage, meaning you could be prone to palpitations, anxiety and headaches. It is important to test your tolerance slowly and build up your body’s response to such supplements like these-especially if it is your first time taking them.
This applies to all other active ingredients that generate heat too, such as Bitter Orange, Green Tea Extract etc. It is always a good idea to read up and do your research about the stimulants, so you are fully aware of what the possible side effects are. Especially, if you are taking other supplements alongside these within your routine, such as pre-workout powders, for example.
Value for money: Grenade
Priced at £35 for one month’s supply, Grenade trumps it by providing the same supply and dosage for £25 – a whole £10 cheaper!
The only way that Instant Knockout can compete here is, if you consider purchasing the multi-box bulk deal, where you can buy 3 for the price of 2.
This offer is limited to Instant Knockout's own website however, and stocks don’t usually last long. Meaning, you would have to keep an eye out, and act fast!
Where can you find Grenade?
Both supplements can be found on their own official landing page promotional websites. You can also utilise Holland & Barrett’s and Amazon’s online supplement store too, which often provides great discounts throughout the year.
Most Versatile: Instant Knockout
It should definitely come at no surprise here that Instant Knockout probably is the most versatile fat burner when compared to Grenade. I don’t know about you, but when looking at a nutritional label, the longer one is, the less confident I actually am in the product.
Instant Knockout uses 100% approved and natural ingredients, with no proprietary blends in sight. In addition to this the directions of dosage are less specific when compared to Grenade, meaning you can take them whenever you choose, whenever you please, and you can choose to evenly spread them out.
Overall winner and verdict: Instant Knockout
No surprise there, right? I decided to select Instant Knockout between the two fat burners, after looking through existing supplement reviews as well as critically evaluating between the two. Sure, Grenade comes in better when price is concerned, however we all know that price is never the whole picture.
The side effects from Grenade have been reported to be higher, due to the higher doses of caffeine involved, found within the multiple caffeine stimulating ingredients used (112.5 mg vs 75 mg in Instant Knockout). It also has come to my attention that the doses of Grenade are much smaller, despite the longer list of ingredients. So you could essentially be paying money for something that really is not doing its job effectively.
Therefore, Instant Knockout wins because of its stronger nutritional profile, great testimonial reviews, and oh, did I forget to mention that there is also a 90-day guarantee available too? Well, there you go. Go forth and buy!
