Grenade Fat Burner Review

Grenade Fat Burner is a weight loss supplement that is available to buy from high street stores as well as online. It is claimed to aid weight loss via the process of thermogenesis, which might also boost the metabolism. It is also said to help with appetite suppression. Whether or not the product is likely to work in these ways is debateable. The product contains several stimulant ingredients; these might cause unpleasant side effects for some users.

Claimed weight loss benefits

The manufacturers claim that the main way in which their product works is by boosting your metabolism. This will supposedly help you to get rid of fat more easily as you burn it through exercise, and they also claim that their product will suppress your appetite so that you are able to manage your weight in a more effective way.

How Grenade Fat Burner Works


The manufacturers claim that this product works by using caffeine to liberate energy from the fat cells, and then adding cayenne pepper to help maintain a higher level of metabolic activity. The weight management process is supposedly supported by green coffee and green tea, and bitter orange also has its own part to play (although the website does not make it clear what this part may be). Looking at the clinical trials behind the ingredients, it does appear that caffeine may have some effect in terms of boosting the metabolism and raising your energy levels, though this effect might not be experienced to a significant extent.

Most of these ingredients have also been seen elsewhere in other diet pills and supplements, and are commonly said to help with weight loss results – though we will have to look at the clinical studies in more detail if we want to understand whether or not the claims that the company makes for the ingredients are correct.

Key Grenade Fat Burner Ingredients


Knowing about the key ingredients in any supplement that you take is always very important, as it means that you can avoid any side effects that come along with them as well as knowing whether you will personally have any adverse effect due to an allergy or interference with an existing condition. The ingredients are also what the company claims will help you to lose weight in the first place, so taking a look at them can keep you better informed as to what the supplement can do for you.

Green Tea Extract

The biggest ingredient in this particular supplement isgreen tea extract, which has been researched to potentially have some weight loss effect – though this is by no means certain. The ingredient is very common to weight loss supplements and is rarely associated with side effects.


Caffeine is a stimulant that is best known for giving you an energy boost that could make your workouts more effective. It is thought to improve energy expenditure and so might boost the metabolism.

Bitter Orance

Bitter orange is another stimulant ingredient. Also known as Citrus aurantium, this ingredient has been associated with some very severe side-effects, such as strokes, heart attacks, and high blood pressure. It is thought to have appetite suppressing effects, as well as the potential to increase fat burning and boost the metabolism.

Cayenne Pepper

Cayenne pepper contains capsaicin, a chemical that has been said to cause thermogenesis and so might increase energy expenditure. The ingredient is generally thought to be safe though its potential weight loss properties have not been proven in studies.

Green Coffee

Green coffee is extracted from the beans of coffee beans before they have been roasted. The ingredient contains caffeine and so might have the same effects as this ingredient on its own. It also contains a substance called chlorogenic acid that is thought to be beneficial for weight loss.

Clinical Studies

Clinical Researcher 538

In order to understand more about whether the Grenade Fat Burner supplement will work for you, it is necessary to look at things in a more scientific manner. We can do this by taking a look at the clinical studies that have been done regarding the supplement and the ingredients that are in it. Unfortunately, we cannot find any clinical trials which have been carried out on the product itself; this means that we have to take a little bit more time looking at the ingredients and figuring out if any of them might be effective for weight loss.

Green Tea Extract

We will take a look at green tea extract first, as this is touted on the website as being one of the most effective parts of the supplement and the one that really helps it to pack a punch in terms of weight loss. However, scientific studies seem to suggest that there is not much to be gained in terms of weight loss from most parts of green tea. Whilst green tea has been shown to aid weight loss in some studies, the effects are only small and might be dependent on certain factors.

Bitter Orange

Next up in the ingredients list is bitter orange, and we have seen this come up time and time again in different weight loss supplements. Some research suggests that combining bitter orange with caffeine and St John’s wort will help reduce weight when combined with a low-calorie diet. Other studies have indicated that the ingredient might be beneficial for increasing the metabolic rate and boosting thermogenesis.


Caffeine is a classic ingredient when it comes to weight loss, and the fact that it is included here does not come as a surprise. It has been rated as possibly effective for weight loss, when given in combination with other ingredients. It seems that combining caffeine with ephedra can have good results over the short term, though the main effect that caffeine will have on you might be in terms of increasing your ability when you are exercising. This will mean that you will be able to exercise more and for longer, thereby burning more calories, but only if you combined the Grenade supplement with a healthy workout regime.

Green Coffee

Studies have suggested that green coffee may well be effective at causing increased weight loss, though the research in this area is at the moment only in the preliminary stages. More research will need to be done before we can say for certain that this is the case.

Grenade Fat Burner Side Effects

Woman With Stomach Ache 538

The main area that you need to look out for in terms of side effects is the fact that this supplement contains several different types of stimulant. This means that you might experience the typical side effects that can be caused by taking more caffeine then your body is used to, such as jitteriness, headaches, difficulty with sleeping, irritability or anxiety, irregular heartbeat, dizziness, confusion, and more.

The side effects that you could experience from ingesting bitter orange include panting, strokes, high blood pressure, headaches and migraines, heart attacks, and other serious effects concerning your organs. You should be very careful taking this supplement, and should stay well away if you have any pre-existing medical conditions or are pregnant or breastfeeding. It is always advisable that you speak to your doctor before you start to take this supplement.

Green Tea Extract

The first ingredient that we can look at in terms of side-effects is green tea. There are plenty of well-documented side effects associated with this ingredient, most of which are associated with the fact that it contains caffeine – meaning that the side effects here will be the same when it comes to caffeine as well. They include headaches, nervousness, problems with sleeping, vomiting or diarrhoea, irritability, irregular heartbeat, tremors or jitteriness, dizziness, ringing in the years, confusion, and convulsions. You may also experience stomach upset and constipation as well as rare cases of liver problems.

Bitter Orange

When it comes to bitter orange, the side effects that you should be looking out for include fainting, strokes, the risk of high blood pressure, headaches, migraines, sensitivity to the sun, heart attacks, and other very severe side effects which are certainly no laughing matter. This is probably the most severe ingredient in terms of side-effects.

Cayenne Pepper

Cayenne Pepper can have some effects on those who are not used to consuming it, such as stomach irritation, sweating, flushing, a runny nose, and irritation to the eyes, nose, and throat.


Finally, phenylalanine is not known to have any side effects in particular, but this is because not enough research has been done into the ingredient to be absolutely sure of what effects it can have.

How to Use

Woman With Pills 538

The list of instructions that is written on the official website for the Grenade product is that you should take two capsules as soon as you wake up with a glass of water, before you have eaten anything. Half an hour before you have lunch, you should then take another two capsules with a glass of water.

The best instructions are to consume just one capsule twice per day for the first week of taking the supplement, in order to be sure that you will be able to tolerate it. This will help you to get started, and also means that you will be aware of any side effects before they become too serious. They advise that you do not take more than four capsules per day, and that you drink at least eight glasses of water. You can take two capsules before you start a workout in order to give yourself a boost.

This product is not recommended for those who are pregnant, breastfeeding, under 18, or have any history of cardiovascular problems. It is recommended that customers consult a doctor before taking this product because the safety of some of the ingredients has not yet been established.

Who Makes It?

Grenade products are sold by some major retailers and have had some strong reviews in the press. The company has a large range of other products available as well, all of which are available on the official website. They also offer trial samples of some of their products.

They have endorsements in the form of Team Grenade, who are a set of fitness models, bodybuilders, dancers, personal trainers, and athletes. These professionals claim to use Grenade products in order to stay in shape or build muscle, though as always we should tell you to take these endorsements with a pinch of salt – they often come with financial or other material rewards for the endorsees.

The company is registered in the UK and also lists a UK address on their website, as well as the option to contact them via a submission form, which means that you should be able to get in contact with them if you need to.
