The Best Bentonite: Our Picks

Guide: Questions you should ask yourself before buying bentonite

What is bentonite?

Betonite is a mineral clay that was first discovered in Fort Benton, a small town in Montana, USA. Bentonite is now also mined in other countries, such as Germany.

Bentonite consists of up to 95 percent montmorillonite, a mineral that is classified as a phyllosilicate. Bentonite is formed by the weathering of volcanic ash and is composed of various clay minerals.

How is bentonite used?

Bentonite is used in many different ways. It can be used as cat litter, in cosmetics, in horticulture and in alternative medicine. It is used as a wash or clay in skin care or as a dietary supplement for internal use.

Bentonite can be purchased as a powder or in capsule form and is also offered in combination with other raw materials such as zeolite or healing clay.

How does bentonite work?

The special thing about bentonite is that it has a high absorption capacity and can bind pollutants of all kinds well. The mineral clay attracts metals, pollutants and bacteria to itself and holds on to them so that this pollutant complex can later be excreted with the stool.

Radioactive particles are also bound to bentonite and then broken down in the body. Bentonite therefore has a detoxifying effect and can also remove heavy metals from the body. The pollutants, metabolic waste products as well as bacterial or mould toxins are absorbed by bentonite at an early stage in the digestive system and therefore no longer enter the bloodstream via the intestinal mucosa.

Consequently, organs such as the liver or kidneys are relieved of these substances and can regenerate. Furthermore, the intestinal mucosa is protected because the harmful substances are bound and the intestinal flora as well as the intestine can increase their activity by improving the absorption of food and nutrient supply in the body.

In general, bentonite has been used for various indications such as diarrhoea, abdominal cramps, loss of appetite, malaise, headaches, nausea and general weakness.

Bentonite has a strong absorption capacity and can thus bind harmful pollutants, heavy metals and bacteria well and eliminate them from the body. This relieves the detoxification organs and the body can regenerate.

What ingredients are present in bentonite?

The most important ingredients of bentonite are aluminium, silicon, sodium, calcium, magnesium and crystal water. Crystalline water means that water is bound in a solid body.

Bentonite is usually present as a fine, homogeneous, greyish-white, yellowish to pinkish powder that can be easily dissolved in water and then begins to swell.

What alternatives are there to bentonite?


Zeolite is a mineral that is also suitable for detoxification. It consists of aluminium, silicon and hydrogen. Zeolite has a high absorption capacity, whereby excess acids, bacterial toxins and inflammation-promoting substances, free radicals and metabolic products can be bound.

People suffering from diarrhoea, flatulence and intestinal fungal infections can also use zeolite to eliminate fungal toxins in the body.


Compared to zeolite, bentonite contains a montmorillonite gel film, is capable of swelling and has a gentle detoxifying and at the same time protective effect on the mucous membrane of the gastrointestinal tract.

Therefore, bentonite is also suitable for people with a sensitive gastrointestinal mucosa. Bentonite only binds toxic substances; health-promoting substances such as vitamins or trace elements are not bound.


Psyllium seeds consist of 87 percent dietary fibre and therefore swell in the intestine. These are used in cases of constipation to bind the softening of faecal deposits and released putrefactive products to the swelling mass.

The psyllium seeds are added to a glass of water, after which a gall is formed which promotes the swelling of the stool. Psyllium can regulate the metabolism of blood fat and glucose and excrete faecal bile acid through the soluble dietary fibres.

How much does bentonite cost?

The price of bentonite in powder form ranges from €19.80-74.50 per kilogram. The prices of bentonite can vary greatly on the market. The content of montmorillonite should be checked in any case, the higher the percentage and the purer the product the better the quality. Generally, the powder is cheaper than the capsules in pharmaceutical quality.

Zeolite is also offered in capsules or powder form. The price range is between €39.60-€70.00 per kilogram.

Psyllium seeds are most often offered ground. The price ranges from €16.90-26.00 per kilogram. Some psyllium products are offered in organic quality.

Others are conventional. Therefore, it is important to pay attention to the exact labelling on the packaging.

Product in powder form price range per 1 kg
Bentonite €19.80-74.50/kg
Zeolite 39,60-70,00 €/kg
Psyllium 16,90-26,00 €/kg

Decision: What types of bentonite products are there and which one is right for you?

It is recommended to buy bentonite only in the form of a medical product that is class IIB and suitable for medical use. Also, the product and its manufacture and quality should meet the requirements of the European Pharmacopoeia and have a granule size that is fine but in the nano range.

The medical devices should also conform to CE number 0481, which indicates that the product has undergone rigorous safety assessments as well as a strict quality control system. CE marking is a legal requirement for companies to reassure consumers that these medical devices are suitable to be placed on the market.

The marking on the product consists of the CE logo, which is accompanied by a four-digit identification number of the testing body 0481.

What distinguishes bentonite products for external use and what are their advantages and disadvantages?

Bentonite is often used externally for face masks, compresses, bandages or wraps. For this purpose, the mineral clay is mixed with cold or warm water until a spreadable paste is formed. This can then be applied 2 to 3 mm thick to the desired skin areas.

Instead of water, herbal tea can also be used as a liquid, e.g. to benefit from the anti-inflammatory effect of camomile or calendula. A bentonite face mask should be left on for about 30 minutes or longer until the layer has dried completely.

During this time, the paste draws the harmful substances, secretions (pus) and sebum out of the skin, blood circulation is promoted, the skin becomes firmer and inflammations can recede. Afterwards, the paste is washed off with lukewarm running water. For people who suffer from acne, bentonite is a great solution to get a clearer skin again.

A face mask with bentonite can reduce blemishes and draw out excess sebum and pus from the skin. Unwanted pimples can be reduced by such a treatment. The skin becomes more beautiful and clear again.

Below you will find a recipe for a detox mask you can make yourself. The amount is sufficient for two applications.

Amount of ingredients Effect
1 tablespoon of bentonite Draws heavy metal residues and toxic substances out of the tissue
1 tablespoon green mineral clay Can bind toxins and dirt, loosen sebum and dead skin cells
1 tablespoon matcha green tea powder Stimulates the growth of new skin cells, skin ageing is delayed
1 teaspoon organic honey has a moisturising and anti-inflammatory effect
1 tablespoon jojoba oil Makes the skin supple and regulates sebum production
1 drop of essential lavender oil Calms the skin and has a harmonising effect
1 drop of essential tea tree oil has a disinfecting and antibacterial effect

Mix all the dry ingredients together in a mixing bowl and then add the liquid ingredients. Mix everything well. If the mask is too thick, you can add oil and honey. If the paste is too liquid, add clay or matcha powder for a better consistency.

The mask should be applied to thoroughly cleansed skin. The mixture can simply be applied to the face, neck and décolleté with the hands or a mask brush, then leave on for about 30 minutes and rinse off with lukewarm water. The eye area should always be omitted. The mask can be applied once or twice a week for a more beautiful complexion.

  • Versatile application for face masks, overlays, compresses, bandages or wraps
  • pollutants and sebum are drawn out of the skin
  • blood circulation in the skin is promoted
  • skin becomes firmer
  • has an anti-inflammatory effect
  • Some time is required to make your own face mask

Another way to use bentonite is in the form of a full bath. In this case, 12 tablespoons of bentonite are added to the running bath water, after which the effect is felt on the skin for 20 minutes.

Later, you should pat yourself dry and wrap yourself in a bathrobe and relax for 30 minutes. Finally, the remaining bentonite residues are rubbed off, giving the skin a fresh and clean complexion.

Bentonite can protect the skin and relieve inflammatory skin eczema. For babies who have a nappy rash, bentonite can have a more healing effect than calendula cream. Bentonite can also be stirred into sunscreen, which can increase the protective effect against UV radiation.

What distinguishes bentonite products for internal use and what are their advantages and disadvantages?

The internal use of bentonite can preventively protect the body from diseases and contribute to a detoxification of the body, as unwanted harmful substances are bound in the digestive system before they are even absorbed by the organism.

When used internally, bentonite binds heavy metals such as (mercury, lead, cadmium), aluminium, ammonium and histamine. This relieves the liver and the intestines can be detoxified. The montmorillonite gel film has a protective effect on the mucous membranes of the digestive tract.

  • Pollutant-binding and mucous membrane-protecting property
  • Expectorant effect
  • Supportive effect in diseases of the gastrointestinal tract and liver dysfunction
  • Support in allergies
  • Observe proper intake to avoid overdose
  • Do not use simultaneously while taking medication

So far, no side effects have been reported with the proper use of bentonite. However, if side effects such as constipation, weakness or pallor occur, it is important to inform the doctor. Mineral clay such as bentonite should not be taken at the same time as medication such as birth control pills or thyroid hormones, as the mineral clay can render the medication ineffective.

In general, bentonite should only be taken after the medication, with an interval of at least 2 hours. It is not advisable to take bentonite at the same time as alcoholic, caffeinated and acidic drinks such as grapefruit, orange, lemon and pineapple juice.

Taking bentonite at the same time as other medicines such as the contraceptive pill or thyroid hormones may interfere with the effect of the medicines. Therefore, caution is advised when taking bentonite.

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

To find the right bentonite product for you, you should consider the following factors when buying:

  • Monmorillonite content
  • Dosage form
  • No additives, vegan, vegetarian
  • Taste
  • Solubility

The following sections describe the individual criteria in more detail and show what to look for when buying.

Montmorillonite content

Bentonite products are offered on the market with varying amounts of montmorillonite. Very often, products with at least 90 percent are on the market.

Of course, there are also products that contain 100 percent montmorillonite. The higher the proportion in the product, the more intensive the effect.

Products with a lower content are also offered. These should not be used for internal application. For external use, the montmorillonite content can be lower at about (75-80%).

Dosage form

Bentonite can be purchased as capsules or as a powder. The capsules are easy to take and have a neutral taste. The exact dose is easy to control.

The powder can be dissolved with water and taken. For external use, the paste can be used in a variety of ways for different skin problems as already explained above.

No additives, vegan, vegetarian

The products that are offered are very often without additives. The powder itself is very natural. If capsules are purchased, care must be taken to ensure that they are also natural, vegan or vegetarian. Additives are known from the food sector.

These include sweeteners, anti-caking agents, preservatives, flavour enhancers and many more. These are used to improve the shelf life, shape and taste of a food. However, some people have an intolerance to these additives and therefore need to pay more attention to the ingredients of a product.

During a colon cleanse, it is therefore important to protect the body from unnecessary additives in order not to put additional strain on it during detoxification.

It is therefore important to purchase bentonite as a medical product without additives.

When buying products, vegetarians or vegans pay particular attention to the fact that no animal raw materials or ingredients are contained. Most manufacturers already label their products with a vegan logo, which makes it immediately obvious that no animal substances are contained in the product.


The taste of the powder is naturally a little mineral, but this is not noticeable in the capsules.

The taste of the powder is more mineral than that of the capsules. (Image source: / 32375207)

It is best to try the powder and see for yourself how it tastes. It is of course slightly earthy at first. If this bothers you, then it is better to go straight for the capsules.


When buying a powder, it is important that the powder is easily soluble in water. This makes it easier to drink or mix into masks. Most powders are already so fine that they can be dissolved very well.

Facts worth knowing about bentonite

How should bentonite be taken?

Bentonite is best taken alone without other food supplements 30 minutes before meals. It can also be taken 2 hours after eating a meal and immediately in acute cases. In the context of an intestinal cleansing, one should start with smaller quantities, i.e. half a teaspoon, which is dissolved once or twice a day with approx. 300 to 400 ml of water.

In this way, the body can slowly get used to the dose and possible intolerances can be recognised in time. Over time, the dose can be increased, but no more than 1 teaspoon should be taken twice a day, as a very good effect is already visible with smaller amounts.

It is important to note that bentonite is only taken with water and not with other liquids or juices. Sufficient water intake is also essential when taking bentonite capsules. If the body is also fed other food supplements (such as vitamins, minerals, algae, antioxidants, etc.), it is important to ensure a time interval of 1 to 3 hours before taking bentonite.

What are the side effects of taking bentonite?

If bentonite is taken in the correct dosage over a period of 4 weeks or in case of acute need, no side effects have been reported. The mineral clay should not be taken in overdoses and in case of side effects a doctor should be consulted in any case.

How long should bentonite be taken?

Bentonite should be taken as a course of treatment, e.g. 40 days, unless otherwise prescribed by a doctor. You can start with a smaller dose - one teaspoon (3g powder) per day dissolved in 250 ml water and taken with meals. After that, the dose can be increased to 2-3 times a day.

When taking bentonite, it is important to pay attention to fluid intake. If there is not enough fluid, constipation can occur, so it is important to increase the water intake in the body.

Bentonite can be taken as a cure for 40 days. After that you should feel better and be back in your inner balance. It is important to drink plenty of water at the same time so that the detoxification process can work well. (Image source: / Form)
