Bentonite is a commercial name for a specific constituent of many medicinal clays called montmorillonite, which comes from volcanic ash. Bentonite Clay offers many benefits because it contains high concentrations of iron, calcium, magnesium and silica. It has been used for centuries, both topically and internally, for protection from toxins and radioactive substances, as well as heavy metal poisoning.
How Does Bentonite Clay Work In My Body?
When Bentonite reacts with water in the body, it swells up and acts as a sponge, attracting and neutralizing toxins and poisons (primarily throughout the intestinal tract), eliminating these harmful substances through the feces.
Bentonite Clay Health Benefits
Detoxification
Given its action within the body, Bentonite is readily available as an effective cleanse/detoxification substance or paired with fibre as part of a complete detoxification program. It is also used in many yeast-busting formulas, to absorb excess pathogenic bacteria in the gut, helping to restore and balance gut flora. Healthy detoxification and elimination of excess yeast can both result in noticeable improvements in gut motility and absorption of nutrients from foods, improved immune function, increased energy and clearer complexion.
Bentonite has also been reported to treat the following conditions:
- Indigestion and ulcer
- Constipation and diarrhea
- Food allergies
- Viral infection, flu, parasites
- Radiation/ cancer treatment
pH Balancing
Acid-loving pathogens and diseases feed off an acidic internal environment. Unfortunately, due to poor diet, medications, and nutrient-poor soil conditions, among several other reasons, an overly acidic environment is all too common. See more on the health benefits of balanced pH. Bentonite clay is rich in minerals and naturally alkaline, supporting internal homeostasis, including a healthy pH. You can test your pH levels quickly and easily at home, using pH strips (note slightly different ranges, depending on whether testing salivary or urinary pH), available at your local health food/supplement store.
Bentonite Clay Supplement Usage
Bentonite clay is available as a supplement in both liquid and powder form. Look for a food-grade supplement as there are many topical application products on the market. Most should be mixed with water; however, it's important to follow the dosing instructions on the product closely.
Safety Information
Bentonite is not to be used during pregnancy and while nursing. It is also extremely important to take Bentonite away from all supplements and foods of nutritional value, as it will absorb these substances and negate their nutritional benefit. Take one hour before or two hours after a meal or ingestion of supplements or medications. It is recommended to take a probiotic following a round of Bentonite, as it can deplete levels of 'healthy' bacteria. Bentonite should be taken with plenty of water.




I've been using bentonite clay for years. I used it first internally as part of a detox program for candida yeast. As the article mentions above, it absorbs toxins, which is why it's a good idea to use it when you're detoxifying, especially yeast. When you kill off the yeast overgrowth, alot of toxins are released called "mycotoxins", which can make you feel bad for a little while. But, when you take bentonite, the clay absorbs those toxins and you just excrete them instead of reabsorbing them.

Pithy but pointed!! This was a short article but I learned quite a bit about bentonite clay from your article, including:
1. Bentonite is the commercial name for a specific constituent of many medicinal clays known as montmorillonite
2. It is extremely important to take Bentonite away from all supplements and foods of nutritional value, as it will absorb these substances and negate their nutritional benefit
3. Bentonite has a pH balancing effect (maybe that is why I have sometimes seen it in natural mouthrinse and toothpaste products!)
4. It is recommended to take a probiotic following a round of Bentonite clay, since the clay can deplete levels of 'healthy' bacteria
Thank you for another article that taught me something(s!!) new :D
