Scientific Facts About Nutritional Clay

Posted on April 16th, 2017

There are many types of nutritional clays that may perform different functions and that it why it is very important to choose a nutritional clay that will fit the needs for you, your family and your family pet.

Going to the internet, you should be able to find a company that carries the nutritional clay you will need.

Please realize there are a number of different nutrition clays that will help you, health wise in the same way.

Clay deposits have various uses that range from internal to external medical uses, to their uses in industry.

There are mixed opinions among the scientific world as to the use of clay, however most of the scientific community does believe the following:

Clay minerals all contain oxygen, silicon, potassium etc. and their basic structure begins as a sphere, which is the basic building block of clay minerals, as are amino acids the basic building blocks of proteins.

The actual clay structure will determine the use of that particular clay.

The actual clay structure is referred to as a single silica tetrahedron.

This particular clay structure is the one that is found in Calcium bentonite, which may be the nutritional clay of choice for internal and external medical use.

The name montmorillinite originated from the clay deposit found in Montmorillon France.

Of interest, montmorillinite is only found in the United States, Italy and France.

Another type of clay known as bentonite was first discovered in Fort Benton, Wyoming.

Illinite was another clay type that was found in Illinois.


The Kaolin group is used in Kaopectate.

It has the ability to absorb various harmful bacteria and toxins however, its main use is to bulk up the digestive system and help to stop vomiting and diarrhea.

The Illinite group is a green, mineral clay that comes from biological sea beds and other marine deposits.

The Smectite group has the ability to absorb toxins, damaging heavy metals, bacteria and radiation.

The most important clay that is included in this group is Calcium Bentonite.

Calcium Bentonite and Montmorillinite are the only “living clay” that absorbs and adsorbs.

The Bentonite group occurs in natural deposits and depending on the structure of the bentonite in the deposit, will determine if the clay can be used for medical purposes or only for industrial uses.

The term bentonite is actually a trade name as already mentioned, and first discovered at Fort Benton, Wyoming.

The mineralogists consider bentonite to be in the smectite clay group.

There are different structured bentonites that can be used medically and others that are used to seal ponds and make crayons and for other industrial uses.

Often the term montmorillinite and bentonite are used inter changeably and some have the same function as montmorillinite and some have different functions.

The bentonites and montmorillinites that are the same, either come from volcanic ash or old biological sea beds that have been exposed to intense heat for long periods of time.


Adsorption = is the ability of a clay to have toxins, bacteria, radiation and damaging heavy metals adhere to the outside surface of the clay structure due to their negative surface ions.

The adsorption occurs due to the clays negative electrical surface charge that causes the positive charge carried by the toxins etc, to be neutralized and in doing so, allows the body to excrete the neutralized toxins, bacteria, radiation and damaging heavy metals.

Absorption = definitely occurs slower with the clay structure.

Unhealthy contaminants are absorbed within the clay structure between the many layers, and the more contaminants that are absorbed, the more the clay will expand.

A negative charge is held in between the layers of the clay structure to neutralize the toxins, bacteria, radiation and damaging heavy metals.

Therefore the difference between adsorption and absorption is that the neutralized contaminants either stick to the surface of the clay structure for excretion or are absorbed internally for excretion.

However, some clay’s will not only absorb the contaminants but will also absorb nutrients, vitamins and supplements which may harm the human or animal.

Fortunately the montmorillinite clay has both the abilities to adsorb and absorb only the contaminants and not the nutrients, vitamins and supplements for excretion.

Other physical features that would encourage you to only use a montmorillinite clay for better health is due to its finer granular size, which includes much thinner layers that allow for the production of greater amounts of neutralization of contaminants to occur for excretion from absorption.

From an adsorption stand point, looking at the neutralization by the surface negative ions, Ran Knishinsky reports in his book The Clay Cure, “ according to an article on clay (Lei 1996), an mineralogist at MIT, Robert T. Marin, states that one gram of montmorillinite a has a surface area of 800 square meters”. According to Mr. Knishinsky,” this is about the surface area of 10 football fields”.

This is the reason I have used nutritional clay that contains Calcium bentonite for my patients, my family, our family pets and myself for the last 35 years.

I recommend the calcium bentonite from Earth’s Natural Clay which I also recommend on my website under Foods and supplements.

These are just some of my thoughts.
