Ancient Purity presents one of the most trusted, effective and powerful healing clays, the original Powerhouses of Detox, extensively tried and tested... Bentonite Clay. It is absorbent and swelling. When it becomes mixed with water it rapidly swells open like a highly porous sponge. Then toxins are drawn into the sponge through electrical attraction and once there, they are bound. Bentonite Clay carries a strong negative charge which bonds to the positive charge in many toxins. When it comes in contact with a toxin, chemical or heavy metal, the clay will absorb the toxin and release its minerals for the body to use. Bentonite Clay is a lot more than just a detoxification tool, like many natural substances it is multi-beneficial for the human body.

It helps getting oxygen to cells as it pulls excess hydrogen and allows the cells to replace it with oxygen instead. Animals in the wild are drawn to clay deposits by instinct, they have been observed licking the clay as part of their everyday diet as well as rolling in it to get relief from injuries. Bentonite Clay has a high concentration of minerals including Silica, Calcium, Magnesium, Sodium, Iron and Potassium. Bentonite Clay acts upon the GI tract through its absorption of various toxins, pathogens, metabolic wastes, impurities, chemicals and heavy metals. Bentonite Clay is a great adjunct for general cleansing, detoxification, and revitalisation of the entire digestive tract.

Detox Your World with Bentonite Clay

"In a world where dietary choices are poor, environmental pollution is heavy, stress levels are high, and exercise is often the last priority, internal cleansing is more important than ever for optimum health." - Dr Bernard Jensen.

Fights Fluoride... One study found that Bentonite Clay, when combined with magnesium chloride, successfully reduced fluoride contained in fluoridated water. This may provide hope for the development of a natural filtration technique in the future, especially considering the rising concern of fluoride on human health. 

Combats Dietary Toxins... Aflatoxin is a type of mould-like compound produced by organisms that thrive on a variety of different food crops. These toxic substances are detectable in peanut butter and some cooking oils, and research shows that they can interfere with the functioning of the immune system. Aflatoxins may also contribute to possible liver damage. Animal models have shown that Bentonite Clay may reduce health damage associated with the ingestion of dietary aflatoxin. 

Bentonite Clay... Clean, Safe, Effective

Bentonite Clay... Clearing Out

Fights Environmental Toxins... Volatile organic compounds (VOCs) is a term describing an assortment of chemicals emitted from cleaning supplies, paint, office equipment, permanent markers, pesticides, building materials, and hundreds of other everyday items. Breathing in these compounds is commonplace for many people, as indoor paints often contain many of these health-damaging chemicals. Bentonite Clay has been shown to adsorb VOCs, possibly reducing human exposure to these dangerous compounds. Determining the proper application of Bentonite as a VOC-reducing agent is still being researched.

Combats Toxic Metals... Bentonite Clay is typically used for cleansing the body of toxic metals, compounds that may degrade the health of the body over time. The most damaging toxic metals are mercury, cadmium, lead, and benzene, compounds contained in some processed foods (especially those with high fructose corn syrup), drinking water, building materials, and the environment. One study has revealed that Bentonite Clay may be helpful for reducing these harmful metals.

Bentonite Clay - More than just Detox

Immune System...

Bentonite Clay has been shown to be fighting against agents responsible for reducing the effectiveness of the immune system and animal models show that Bentonite Clay may boost the immune system.

In one study, broiler chickens were fed food containing aflatoxins to test their immune response. Aflatoxins seemed to initiate unfavourable effects in the immune system, an action that can increase the animals’ predisposition to a number of diseases. Following the administering of Bentonite Clay, the aflatoxins’ immune-degrading effects were significantly suppressed. 

Bentonite Clay and Loose Bowels... In his book "The Clay Cure", Ran Knishinsky discusses how loose bowels can be combatted through the use of Bentonite Clay because of its ability to bind stools. Bentonite Clay might work right away by binding to irritants in the gastrointestinal tract. It's a good idea to mix the Bentonite Clay with one cup of applesauce, which not only makes the clay more palatable but also adds pectin, which is another binding agent.

Cleans Contaminated Soil... Soil near busy highways or roads can often be contaminated with a variety of metals, pollutants, and toxic chemicals. Much of the contamination in soil has been built up for decades, and many of these chemicals can interfere with the quality of the soil and crop production. Organic chemical compounds, like benzene, toluene, and xylene, are often found in contaminated soil. These aromatic chemicals are carcinogenic, and exposure to them over time can lead to negative health effects. Bentonite Clay may be helpful for reducing soil contaminates by acting as an amendment to the chemically-adulterated soil. 

Bentonite Clay is a Healing Clay

Bentonite Clay & Weight-Loss

A Calcium Bentonite Clay detox drink fills the stomach and suppresses hunger, helping you ease into balance eating habits and sensible portions. Many people in Haiti eat small clay cakes for the purpose of losing weight and because they cannot afford the basic food. An article from National Geographic said that poor people of Haiti eat clay cookies made up of clay, water, vegetable oil, and salt. This may not be the ideal snack. Ancient Purity certainly wouldn't want anyone consuming vegetable oil and table salt, but it may inspire you to create your own Bentonite Clay cookie and it shows how the clay can aid in weight management.

Mix Bentonite Clay and Ancient Purity’s Apple Cider Vinegar together to help with Weight-Loss.

In the Apple Cider Vinegar page we talked about its long term use for weight-loss, but here we can talk about making it work faster when mixed with Bentonite Clay. Specifically for weight-loss you can do the following.

  • 1 Large glass of filtered clean water.
  • Add 1 Tablespoon Bentonite Clay.
  • 1 Tablespoon of Apple Cider Vinegar (with "the mother" only)
  • Take it on an empty stomach at least 2 hours before a meal.
  • Can be done twice daily.
  • You can take the drink 2 hours before your meal.

This new drink might keep you energetic throughout the day, as well as detox you. Bentonite Clay easily binds to all the toxins and pulls it out of your body through defecation. Apple Cider Vinegar is just amazing, go read about it on our Apple Cider Vinegar page.

Using Bentonite Clay with Psyllium Husk & Magnesium

bentonite clay supplement

Bentonite Clay is one of the most tried and tested natural health products, in a detox protocol and as a stand-alone powerful tool for health. Our everyday lives expose us to pesticides, lead, and trace metals like copper on a regular basis.

These toxins can accumulate in the body and keep it from functioning correctly. Bentonite clay has been studied and found to absorb these toxins and others.

In fact, some people even eat small amounts of calcium bentonite clay as a way to cleanse the body of these harmful elements.But it can be complimented with some other incredible elements...

We recommend using Bentonite Clay in conjunction with Psyllium Husk. These two substances will work together and may give you outstanding results. Psyllium is a soluble fibre that comes from the seeds of the herb Plantago ovata, which is widely grown in India. It is a common ingredient in laxatives. Toxin overload impairs various processes in your body, including metabolism.

Psyllium fibre absorbs moisture and swells in the colon, helping to ease bowel movements and the removal of toxins. Magnesium Spray is essential to use before Bentonite Clay if you really want to get the very best out of this incredible natural and powerful detox tool.

Magnesium really should be one of the first things you make sure you've got enough of. (See "Related Products").

Bentonite Clay - History, Research and Studies

Bentonite Clay (also referred to as Montmorillonite) is not a mineral, but a commercial name for "Montmorillonite", the active mineral in most medicinal clay. The name "Montmorillonite" comes from the city Montmorillon, in France, where the medicinal clay was first identified. The name "Bentonite Clay" refers to clay first identified in Cretaceous rocks in Fort Benton, Wyoming, USA. Although Bentonite deposits can be found throughout the world, many of the largest concentrations of clay are located in the Great Plains area of North America.

According to a 2006 study published in Radiation Protection Dosimetry, which was performed by a team of scientists led by V. Correcher and entitled "Thermal Stability of the Thermoluminescence Trap Structure of Bentonite," Bentonite Clay was studied because of its known capabilities to break bond links, form hydrolysed ions, and redox reactions. The study documented the "exponential distribution of trapped electrons."

Bentonite Clay... A Natural Solution

how to use bentonite clay for detox

Dr Weston A. Price

Dr Weston A. Price, in his book “Nutrition and Physical Degeneration” reported that several native cultures including those in the Andes, Central Africa and Australia consumed clays in various ways, most often by carrying balls of dried clay in their bags and dissolving a small amount of the clay in water with meals to prevent poisoning from any toxins present. In a study from Arizona State University, Bentonite Clay was found to be highly effective at killing bad bacteria. What is promising as research continues in this area is that depending on the method in which the Bentonite Clay kills the infection, it may not be possible for the bacteria to develop a resistance to it as it does with antibiotics.

In another scientific study, Bentonite Clay was tested to determine its efficacy in reducing high-energy gamma irradiation of adenine. According to chemists at Duke University, adenine is one of the most important organic molecules found in the human body. Adenine is an integral part of human DNA, RNA, and ATP. In this study, published in Cellular and Molecular Biology in 2002, irradiated adenine recovered much quicker in systems containing clay than in those which did not contain clay. Results showed that Bentonite Clay often acts as a surface protector against radiation of adenine.

Bentonite Clay... Closing Thoughts

Bentonite clay is natural clay with a fine, soft texture. When mixing it with water, the clay forms a paste. Some people use this paste for cosmetic or medical benefits, such as combatting rashes, diarrhoea, weight-loss, and pimples or as a natural hair mask. Bentonite Clay is present in numerous skin products, but some persons also add it to foods or beverages with the goal of relieving digestive issues or removing toxins from their bodies. Scientists and researchers believe that Bentonite Clay works by adsorbing dirt and oils from the skin. 

Removing toxins from the body might be one of its most well-researched benefits. In addition, Bentonite Clay might be a helpful supplement for those trying to lose weight. Because this clay can stick to toxins, it might help to regulate a person’s digestive tract. Some studies suggest that adsorbent clays such as Bentonite might aid alleviate virus-related digestive difficulties, such as loose bowels. As with any natural remedy, those with health issues should talk with their doctor before using Bentonite Clay making sure it is safe.

Our Bentonite Clay is best taken on an empty stomach, preferably in the morning or late evening, or at least 2 hours between meals. Adequate intake of fresh water is vital due to the absorptive nature of this product. 

Adults for general health maintenance: Mix 1 heaping teaspoon of Bentonite Clay in a large glass of pure water or juice and drink once daily. Alternatively, a heaped teaspoon can be added to a litre of clean water (glass bottle) and sipped throughout the day. Or as directed by your healthcare practitoner, do not exceed recommended daily intake.

Children: Take 1/2 teaspoon per 50lbs of bodyweight. Do not exceed the recommended dose.

Face Mask: For smooth and healthy skin, make a paste of Bentonite and water and apply to face as a mask (a similar mask is used in many spas). Leave on for 10-20 minutes and wash off with warm water. If you feel a pulling and tightening sensation, it means the mask is working. Typically do this once or twice a week. Note: You may experience slight redness of the skin directly after removing the mask. This is totally normal and should disappear in about 30 minutes. If you’re nervous about this, perform a spot test elsewhere on your body 24 hours prior to using this mask on your face.

Detox Bath: First we highly recommend using Magnesium Spray as this will massively help detoxification happen. Then add about 1/4 cup of Bentonite Clay to a bath for a relaxing detox bath that softens skin.

Bentonite Clay Foot Baths: While not quite as effective as a full body soak, are proving to be very beneficial as well. So, if you can't do a full body clay bath, a Calcium Bentonite foot bath is the next best thing. To prepare your clay foot bath, you'll need a plastic tub. Most people prefer a container that's deep, in which they can submerge their whole foot. Do not use a metal tub because the metal will react badly to the clay. A plastic shoe box or even a five-gallon plastic bucket will work fine. Place a towel on the floor to catch any splashes and set your tub on the towel. Fill the tub about 50-60% with warm water. Add half a cup of Calcium Bentonite Clay or more and whisk it around until it's fully dissolved. Submerge your feet and relax for 15-30 minutes. If some of the clay settles to the bottom of the tub, that's fine. You can wiggle your feet a bit to mix it back into the water. After your foot soak, dry your feet and apply a natural moisturiser.

For Hair: As a shampoo replacement Bentonite Clay may also be used as a shampoo trapping and removing dirt, debris, build-up and other particles from your hair and scalp.

  • Mix 1 to 2 parts Bentonite Clay.
  • Slowly add water to the clay until you achieve a pancake mix texture.
  • Apply to your hair (dry or wet).
  • Allow to set for between 15 - 20 minutes.

On the Skin: Externally, apply a paste of Bentonite Clay and water on any skin irritation like blemishes, insect bites, cuts, skin itching, or burns. Leave it on until it dries and wash off. This is said to be especially calming to itching from various skin health issues.

Skin Poultice for Bites/Burns/Cuts/Stings: For more severe issues, create a poultice by putting a thick layer of clay on the skin and applying a wet gauze or cloth over it. Wrap the area and leave the poultice on, changing every 2 hours.

WARNING: Do not store or mix Bentonite clay in metal. Keep container closed and in a dry place when not in use. Do not take the clay with medications and/or dietary supplements as it may bind with other substances, possibly reducing their effectiveness. Please consult your physician if you if you are taking any prescription medication.

In some cases, a Psyllium - Clay colon-cleanse can cause constipation. The reason Bentonite Clay may lead to constipation is because of its ability to absorb many times its weight in pathogens and toxins. Degenerative conditions in the digestive tract can also lead to constipation. Taking vitamin C or magnesium might help, according to Krohn and Taylor. Also, psyllium can cause bloating or gas and interact with some medications, warns the University of Maryland Medical Centre. Do not take psyllium if you have difficulty swallowing or have kidney disease.

Q - What does Bentonite mean?
A - Bentonite is the most abundant of all clays. The term "Bentonite" is a catch-all for numerous variations of smectite absorbent (swelling) clays derived from weathered volcanic ash. A Bentonite often contains a high percentage of Montmorillonite, Illite or Kaolin clays. For the most part, Bentonites are classified as Sodium Bentonites, Potassium Bentonites or Calcium Bentonites. The one common characteristic of a Bentonite is that they absorb moisture more so than other clays.

Q - What is the difference between Sodium and Calcium Bentonite?
A - Sodium is the most swelling of the clays and as a result the most clogging.  Calcium clays are valuable therapeutic clays both internally and externally and less clogging.  It is important to supplement with extra magnesium whilst using calcium bentonite to balance these two minerals.  Magnesium is most deficient of the two in modern diets.

Q - Can I use calcium Bentonite Clay topically for skin issues?
A - Yes, it works great for chronic itchy skin conditions. Just mix up a small batch following the instructions below (1 part clay, 3 parts water). Apply liberally to affected areas (skin) and let stand for 20-30 minutes. Rinse with warm water. Use 2-3 times per week or as often as necessary for a clean, clear and healthy skin.

Q - Can I use calcium Bentonite Clay on my scalp?
A - Yes, the clay is excellent for helping to reduce itchy rash with flaky scales and itchy scalp. Make a batch consisting of 1 part clay and 3 parts water following the instructions below. You can also substitute apple cider vinegar in place of water for a more pH balanced mixture. Apply liberally to entire scalp and let stand for 20-30 minutes. Rinse with warm water (shampoo optional). Apply 2-3 times per week, or as often as necessary for clean, clear, healthy scalp.

Q - Should I drink calcium Bentonite Clay or use it topically?
A - For skin or scalp conditions like flaky scales and itchy rashes, you will have better results by applying the clay topically 2-3 times per week. For overall body detoxification, you will achieve better results from drinking the clay every day. Doing both is recommended for optimum results and good health.
