The Best Metabolism Tablets in the United Kingdom: Our Choices

Guide: Questions you should ask yourself before buying metabolism tablets

What are metabolism tablets?

Metabolism tablets are designed to stimulate the human metabolism with the help of the ingredients they contain. The desired effect of taking such pills is in the area of healthy and appropriate weight loss, energy production and improvement and stimulation of digestion.

The word "metabolic tablets" is a very elastic and not clearly defined term. It includes appetite suppressants, fatloss preparations, carb blockers, fat burners or even fat blockers. In addition, there are many more terms that fall under the term "metabolism tablets".

Metabolism tablets are primarily used to boost the metabolism. This supports the breakdown of fat.

The substances contained in the small tablets are supposed to increase fat burning, stimulate the metabolism and thus support weight loss. At the same time, some ingredients (allegedly) prevent fattening contents from other foods from being absorbed.

On the other hand, some substances are supposed to inhibit the feeling of hunger and make you feel fuller for longer. Each tablet contains different contents, and their effectiveness should always be strongly questioned.

How do metabolism tablets help you lose weight?

As already mentioned, the substances contained in metabolism tablets are said to have numerous weight-reducing effects. The promises made by the manufacturers should always be checked.

Losing weight simply by taking such pills has not been proven.

The following effects can be achieved by taking metabolism pills:

  • Direct or indirect appetite suppression
  • Increase in fat burning
  • Increased activity of the person taking the tablets due to the high caffeine content of the tablets
  • Reduction in fat and carbohydrate utilisation
  • Increase in basal metabolic rate

Are metabolism pills also suitable for weight gain?

Just as many people try to lose excess weight, there are many who struggle with the opposite. Metabolism pills, which are supposed to shut down the metabolism, are not a sustainable solution for gaining weight.

Depending on whether weight is to be lost or gained - the daily eating and exercise behaviour determines the desired effect.

To stimulate the appetite, natural appetite stimulants such as helpful teas and spices, but also those in tablet form with stimulating ingredients, can be taken. In this case, it is highly recommended to buy them from a pharmacy.

For whom are metabolism tablets useful?

Weight loss tablets are particularly suitable for people who have been working on their desired weight/body for a long time. This group of people is characterised by the fact that they already follow a sports routine and eat a healthy diet for the most part and still want to lose some fat.

In this case, the ingredients in the tablets could lead to the optimisation of the necessary metabolic processes in the body and thus to the reduction of fat.

However, it is clear that without an increase in physical activity and a healthy diet with a healthy calorie deficit, only limited or no success will be visible.

Is it dangerous to take metabolic tablets?

Just like any other dietary supplement, metabolism tablets can cause side effects and can therefore be considered dangerous for the body. For this reason, the package insert should be read and checked thoroughly before taking the tablets.

We have prepared the following table to give you an overview of the possible side effects:

Side effect Description
Insomnia Insomnia may occur due to stimulants such as caffeine. If the preparation is not taken directly before going to bed, this effect should be avoided.
Palpitations Palpitations are usually noticeable by a fast heartbeat and strong palpitations. This symptom can occur as a side effect of metabolic tablets. Since this effect has other negative effects, it is important to avoid tablets with such a side effect.
Nausea A feeling of discomfort in the abdominal area, as well as persistent nausea, are also among the possible side effects of a metabolism tablet. The concentrations of the ingredients contained in the pills can lead to this effect in those taking them.

How much do metabolism pills cost?

Metabolism tablets are priced between EUR 10 and EUR 40, which is in the average range of all dietary supplements.

Most suppliers recommend at least two tablets or capsules per day. Depending on how long you plan to take the weight loss pills, this should also be planned into the available budget, as supplementation could become expensive.

Due to the fact that our body should be supplied with the vital substances in the long term in order to support sustainable fat loss, it is recommended to take them over a longer period of time. These points should be considered before the first purchase.

Are there alternatives to metabolism tablets?

In addition to numerous metabolism and weight loss supplements, there are also alternative ways to stimulate the metabolism. Here we have summarised the top three recommendations that can lead to success if followed over the long term.

Eat and drink

In order to stay fit and efficient, you should drink at least two litres of water a day. A varied and healthy diet, with a little less carbohydrate and a little animal fat, is the basis for your success.

The carbohydrate intake should not be reduced too much, as otherwise the yo-yo effect could follow. Animal fats should be reduced because of their fat-storing effect.

Vital substances

Vital substances are vital for the cell supply of our body and the functioning of all metabolic processes. Therefore, care should be taken to ensure a sufficient supply of the vital substances discussed in the Trivia chapter.

Exercise and rest

In order to effectively lose fat, a good balance between regeneration and exercise is required. Regular exercise in the form of strength training or endurance sports - which can also be learned by beginners - is a good basis.

The muscles built up in strength training increase the basal metabolic rate by consuming a lot of energy. Endurance sports, on the other hand, only build muscles to a limited extent and tend to burn calories.

Too little sleep also has a negative effect on abdominal circumference, according to a study by the University of Leeds in England. The study shows that people who sleep too little are more likely to be overweight.


Decision: What types of metabolism tablets are there and which are right for you?

A functioning metabolism is essential for targeted weight loss. Would you like to try metabolism tablets? Then it is first important to know the difference between the different types of metabolism tablets.

Basically, you can distinguish between four types of metabolism tablets:

  • Appetite suppressant
  • Carbohydrate blocker
  • Fat burner
  • Fat blocker

It is important that you first familiarise yourself with the four types in order to make the right decision. Each form has different advantages and disadvantages.

We would now like to introduce you to the different types of metabolism tablets in the next section. This should help you to find the right preparation for you. In the following you will find a detailed explanation and the advantages and disadvantages of using each type.

What are the characteristics of appetite suppressants and what are the advantages and disadvantages?

The first type of metabolic tablets are appetite suppressants. They are again divided into those that act directly as appetite suppressants and those that are responsible for a stronger feeling of satiety.

The preparations that act on the appetite often contain a lot of caffeine, which leads to an increased level of activity. This promotes weight loss, but caffeine overdose is also possible.

Appetite suppressants, which induce a stronger feeling of satiety, usually contain insoluble dietary fibres. These make you feel full at first, but are not utilised and are fully excreted again. These include bran tablets, but also ground psyllium husks. Digestion is stimulated by the ingredients.

  • Direct appetite suppression
  • Stronger feeling of satiety
  • Stimulates digestion
  • Increased urge to be active
  • Risk of caffeine overdose
  • Risk of constipation
  • Effect only during the period of ingestion

What are the characteristics of carbohydrate blockers and what are the advantages and disadvantages?

Carbohydrate blockers are intended to prevent parts of the carbohydrates ingested with food from being absorbed. Since carbohydrates are usually very calorie dense and contain more calories than other foods, this effect is very positive for weight loss.

The tablets ensure that only a part of the ingested carbohydrates remain in the body and the rest is excreted unused.

With so-called carb blockers, enzymes are blocked and the carbohydrates cannot be broken down. This means that they do not enter the bloodstream as sugar molecules and do not cause the blood sugar level to rise as much. The lower insulin output advocates that fewer fat cells are stored.

  • Reduction in cravings
  • Lower cravings for carbohydrates
  • Possible calorie deficit
  • Digestive problems
  • Risk of nutrient deficiency
  • Danger for diabetics

What are the characteristics of fat burners and what are the advantages and disadvantages?

The so-called fat burners are based on a complex of caffeine, L-carnitine, chromium and B vitamins (including vitamin B3 and vitamin B5). They have a direct effect on the urge to be active due to the caffeine, on the fat metabolism and the hormone balance.

With fat burners, fewer fat cells are stored and more are transformed into energy. Just as with the other types, this form is not an alternative to sufficient exercise and a healthy eating pattern. With these metabolism tablets, long-term use should be avoided, as life-threatening complications cannot be ruled out.

  • Increased urge to exercise
  • Reduced fat storage
  • Improved fat burning
  • Life-threatening complications
  • caffeine overdose possible

What are the characteristics of fat blockers and what are the advantages and disadvantages?

Fat blockers work in a similar way to carbohydrate blockers in that they excrete part of the fat ingested unused. They thus reduce the intake of fats and ensure a faster conversion into energy.

The reduced intake of fats lowers the cholesterol level and thus has a positive effect.

In the same way, caution is advised when taking them. Fats are responsible for the absorption of fat-soluble vitamins. If the intake of fats is too low, this process can be disturbed.

Furthermore, fat blockers often contain critical ingredients (e.g. chitosan and alginate) that cause side effects. These can include diarrhoea, flatulence and incontinence.

  • Reduced fat intake
  • positive influence on cholesterol levels
  • Significant side effects
  • Disruption of vitamin absorption

Buying criteria: You can use these factors to compare and evaluate metabolism tablets

In the following we would like to show you which factors you can use to decide between the different metabolism tablets. These aspects will make it easier for you to compare and evaluate the different preparations.

We hope that this will make it easier for you to find the right product for you.

You can use these points to compare and evaluate the individual metabolism tablets:

  • Ingredients
  • Dosage form
  • Variety of contents
  • Recommended dosage
  • Side effects

In the following paragraphs you can read the necessary information on the respective purchase criteria.


The ingredients contained in the metabolism products should be the most decisive criterion for you when choosing a suitable product. The metabolism tablets contain different ingredients and therefore also provide a varying effect.

Since most metabolic preparations are high-dose tablets or capsules, it is extremely important to rule out an intolerance or allergic reaction based on the ingredients.

To get a better overview of the individual substances and their effects, it is best to inform yourself before buying.

Dosage form

Metabolic supplements are mainly available in tablet and capsule form. Depending on your preference, you can decide which preparation is right for you.

Metabolism tablets are very popular because they are easy to take. The individual ingredients are processed into a tablet through strong pressure and a pressing process. The tablet can then be taken in the desired amount together with water. Depending on the supplier, the tablets contain different ingredients.

Metabolism capsules are taken orally, just like the tablets. Depending on which supplier you get the capsules from, they will contain different ingredients.

Those who value vegan or vegetarian capsules should check before buying. Most products available online are sold in vegan capsules.

Here you can find the most important points in a table:

form of intake Good-to-Know
capsules intake with water, accurate dosage, convenient for on-the-go, regular intake, vegetarian and animal variant
tablets intake with water (optional), convenient use, accurate dosage, plant-based manufacture

Variety of ingredients

Depending on the supplier, different ingredients with varying effects are contained in the metabolism tablets. Furthermore, the concentration of the individual ingredients in the tablet is decisive. Each manufacturer offers different combinations and concentrations.

Below we list the most common ingredients:

  • Caffeine in the form of guarana extract, green coffee or green tea extracts
  • Catechins from green coffee
  • Chlorgenic acid from green coffee
  • Capsaicin from peppers, cayenne pepper or chilli peppers
  • L-carnitine as a fat burner
  • Magnesium carbonate as an enzyme stimulant for fat breakdown
  • Calcium dioxide as an acid blocker
  • Zinc gluconate as a fat binder
  • Ginger powder
  • B vitamins
  • etc.

Whether all these substances actually keep the desired promises of the manufacturers is debatable and therefore remains to be seen.

Recommended intake

The recommended intake also varies from supplier to supplier. In most cases, however, an intake of two tablets per day is recommended.

Due to the caffeine contained in most of the tablets, they should preferably not be taken in the evening when sleep problems already exist. Otherwise, there is basically no non-plus-ultra intake recommendation.

Here again, it is important to listen to your body and also to consider the manufacturer and its recommendation. It is important that the recommended daily intake is adhered to. It is well known that an overdose can cause side effects.

Side effects

Some side effects may occur when taking metabolic tablets. These should be clearly described and mentioned in each package insert. Due to the combination of active ingredients in the preparations, metabolism tablets can have both positive and potentially negative effects on the organism.

You can find out which side effects are very common and therefore also classified as dangerous in the advice section of the topic page.

Facts worth knowing about metabolism tablets

What does the metabolism do?

Metabolism combines all biochemical processes that take place in the cells of the human body.

The metabolic processes in our cells ensure that the nutrients supplied with food are converted or broken down efficiently and optimally. These processes are essentially controlled by our hormone and nervous system.

The metabolism supplies every cell in the body with what it needs, so to speak. This includes energy carriers, auxiliary substances (e.g. vitamins, hormones and enzymes) and building materials. It also removes negative substances such as toxins and waste from the body.

Basically, a distinction can be made between carbohydrate, protein, mineral and fat metabolism, anabolism and catabolism.

If our metabolism does not function smoothly, it can lead to disorders, obesity, lack of energy, concentration problems, digestive problems, etc.

How can I speed up my metabolism without tablets?

Basically, fat is broken down and weight is lost when more calories are consumed, i.e. taken in through food.

This means that if you eat 2500 kcal a day and only burn 1800 kcal a day through exercise and sport, you will not lose weight but gain fat. On the other hand, if you consume 2000 kcal a day and burn 2500 kcal because you integrate a lot of sport and exercise into your daily routine, you will also lose fat.

It is that simple - to lose weight you need to go into a healthy calorie deficit. This is about 200 kcal less than you consume every day.

To boost your metabolism, you should eat whole foods on a regular basis. A healthy and varied diet combined with regular exercise will get your metabolism going again.

What do vital substances have to do with metabolism?

Vital substances are very much involved in a well-functioning metabolism. A lack of vital substances can also inhibit weight loss due to the resulting slowed metabolism.

Vital substances are all vitamins, minerals, trace elements and secondary plant substances that are essential for life. All our metabolic processes are based on an optimal supply of vital substances.

We have listed exactly which components you should pay attention to in the following table:

Vital substances Description Foods with a high content
Coenzyme Q10 Coenzyme Q10 plays an important role in energy production in human cells. If there is too little of it in the organs and tissues, we feel lacking in energy and fat burning is shut down Meat, eggs, nuts
L-carnitine L-carnitine transports the fatty acids of our cells and is therefore involved in energy production from fat. If our need for L-carnitine is not sufficiently covered, muscle mass is broken down instead of fat during physical exertion chicken breast, milk, tuna
Magnesium Magnesium is an essential factor in numerous metabolic processes. If there is a magnesium deficiency, these processes come to a standstill, which inhibits fat loss nuts, pulses, wholemeal products
Vitamin D Vitamin D helps against the yo-yo effect. The vitamin ensures that fat cells that are no longer needed are broken down and excreted by the body. If there is a deficiency, the fat cells that are to be excreted fill up again immediately and fat loss does not take place salmon, cheese, eggs
Omega-3 fatty acids These unsaturated fatty acids promote fat loss. They are more beneficial for weight loss than saturated animal fatty acids tuna, Brussels sprouts, spinach

How do I take metabolism tablets?

When taking metabolism tablets, always follow the instructions and consumption recommendations of the respective preparation. Depending on the product, there are differences in how to take the tablets and when to take them.

Do metabolism tablets require a prescription?

The majority of metabolism-stimulating tablets do not require a prescription. They are also readily available, as explained in detail in the first chapter. Again, no pill can replace a healthy diet and regular exercise.
