Colloidal Minerals - Fact and Myth

Steven E. Whiting, Ph.D.  Institute of Nutritional Science San Diego

With the tremendous success of trace mineral products in the marketplace there naturally will be differences of opinion regarding type, form, source, etc. Unfortunately, most of this 'controversy' comes from the marketing departments of various firms attempting to cast aspersions on competing products.

Many of the companies currently selling liquid mineral supplements have jumped on the bandwagon very recently, doing so with little or no knowledge of the product they are promoting. It is tragic that the biggest source of nutritional information available to the public is the marketing hype delivered by companies whose goal is to simply sell a product rather than provide an education and information source to the clientele they service.

It is amazing to read some companies literature, much of which contains statements which have little or no basis of fact. When you look at a piece of 'negative' material about liquid colloidal minerals, you will very often find, upon reading far enough, that whomever is putting this out is also, just by 'coincidence’, selling a competing product.

This special report is offered in an attempt to clarify some of the confusion and concerns the public has regarding the use of liquid mineral supplements.

That Sensational Mineral Tape

Probably the most famous piece of publicity with regard to colloidal minerals is an audio tape being circulated by a variety of companies.

In the audio presentation, the speaker sets forth many points of fact that cause the listener to sit up and take notice. It has probably been responsible for more awareness regarding minerals than any other single source of information.

Unfortunately, it was delivered as a sales presentation and some of the statements and comments contained therein are stretches of the truth. This, in turn, has led other companies to rebut this audio and to make exaggerated Statements of their own, compounding and further muddying the waters. This leaves the public in the worst position of all – totally confused!

We will first address the issue of ‘colloids'. Because mineral marketers tend to use it in a variety of different contexts. It is no wonder that the term 'colloidal' has caused some confusion. Properly used in present day context, 'colloidal' refers only to particle size.

However due to the fact that mineral researchers in the l93O’s used only organic source minerals in their research, properties they discovered in such minerals are now, unfortunately, attributed by those (who are less informed) to all colloidal minerals. This is a big mistake because, as we shall soon illustrate, there are essential bio-electrical life-supporting properties in organic minerals which inorganic colloidal minerals do not have. Because of the increased absorption, certain inorganic colloidal minerals are in fact, more toxic than their non-colloidal counterparts.

While current popular audio tapes infer that colloidal minerals are somehow 'special', the term colloidal, alone, does not make the mineral bio-avaiable nor does it solely guarantee that the mineral is from a source that is synergistic with the human body makeup. More about this later.

By physical definition, a colloid describes the size of a particle of matter one that neither floats nor sinks in water. Companies wishing to compete with those selling colloidal minerals first argue that there are other forms of minerals that are smaller in size. While this may well be true, particle size is only one of several factors that affect the body's ability to assimilate minerals. Colloids are not the smallest particle size obtainable, but are certainly much smaller than 99% of all other mineral supplements being offered in the marketplace.

Particle size is indeed a factor in mineral absorption since a basic physical law states that the smaller a particle the greater its relative surface area. It is upon this surface area that the body chemistry must act in order to break down and absorb any nutrient. Therefore, colloidal minerals, which are a far smaller size than pills or powders, are better absorbed. Opponents of colloidal mineral supplements further argue that colloids do not diffuse easily through a membrane. This is true. But what these companies' literature doesn't tell, you is that ALL MINERALS, even those in solution which are small enough to pass through a semi-permeable membrane, must first be processed by the body in order to be biologically useful. Colloids, because of their small size, happen to break down much easier than pills or powders due to the increase of the relative surface area upon which the body 's Chemistry needs to act.

Yet another area of confusion regarding the term, colloidal, seems to be the claim that 'colloidal minerals are 98% absorbable'.

The fact is, while colloidal minerals, because of their relative size, are certainly more absorbable than most of the mineral products on the market, we don't know exactly by how much. Mineral absorption may be affected for the better or worse by a variety of factors such as a person's age, physical condition, overall state of health, and the condition of their digestive system.

It has been fairly well established that minerals from rocks and clay (inorganic sources) are the poorest absorbed, probably 20 to 40%. A chelated mineral which has been pre-acidified, preferably by, an amino acid process, has a much better absorption rate since the burden of acidification does not rest with the body chemistry. Chelated minerals are likely absorbed at about 50 to 6O%. Organic colloidal minerals which are smaller in particle size, are also naturally chelated or pre-acidified. Since they have a natural PH of between 3.0 and 4.0, no other chelation process is necessary. Their absorption is very high due to these factors together with one other very significant characteristic which we will discuss shortly.

Colloids, by definition, do not dissolve and become part of a solution. In the case of mineral colloids, this is due to their unique electromagnetic charges which bind them to each other. The body chemistry acts upon these structures, breaking them down into biologically beneficial elements. Most minerals in solution, on the other hand, are in the form of positively charged atoms (cations) which also have a positive electro-magnetic charge. Their charge is the same as the bioelectrical charge of the body and thus they are more poorly absorbed due to the like-repels-like concept of electromagnetics.

Opponent of Colloidal products are fond of quoting from Remington's Pharmaceutical sciences, which states that, "colloidal mineral particles consist of many aggregates and each aggregate contains many molecules." It should be noted that the definition refers to mineral compounds and not pure atomic structures as are found in organic minerals colloids. Elements as found on the periodic table are in their atomic state and cannot be broken down any further.

For example you cannot have a molecule of calcium or boron or any other pure element found in the periodic table. These elements are atomic structures only. They can combine with other elements, forming molecular structures and other substances without number, but in their pure elemental form they are atomic only. The concept of atomic colloids, as opposed to molecular colloids is one which is still not fully understood by the scientific community.

Mineral Marketing Madness

A classic example of employing marketing sensationalism to confuse an issue may be seen as follows:

All minerals are ionic!! There is no such thing as a non-ionic mineral. The term ionic simply refers to something that bears an electrical charge of some kind. All minerals carry an electrical charge -- that's why they are minerals. If this were not so physical matter as we know it would not hold together and the physical universe would come apart.

Chelated minerals are still the best source of minerals for man. Natural organic sourced liquid trace mineral products are naturally chelated with vegetable acids called fulvic acids. It appears that these acids actually do more than merely chelate the mineral but actually contribute to generating the life sustaining negative bio-electrical charges that are responsible for colloidal minerals' greatest benefit to the human biochemistry.

Ignorance abounds in the nutrition marketplace and as this market grows in size it will Continue to attract the ‘big business' element Whose main focus is financially motivated marketing hype rather than fact-based science.

Now let's turn our attention to the all-important issue of...

'Organic' vs 'Inorganic'

Currently there are two types of colloidal mineral products on the market. First, there is the inorganic colloidal mineral product which is a combination of soils & clays (dispersed colloid) and water (dispersing substance). Second, there is the organic colloidal mineral product which consists of a combination of minerals derived from prehistoric plant material (dispersed solid) and water (dispersing substance).

Those inorganic colloidal minerals consisting of soil & clays, whether from plain inorganic sources or chelated inorganic sources, have an electromagnetic charge that is positive. The colloidal minerals from organic sources consisting of plant derived minerals, have an electromagnetic charge that is negative. Whether the electromagnetic charge is positive or negative is a major factor that affects mineral availability and subsequent absorption: unfortunately it is a factor about which very little is understood by manufacturers and consumers alike.

It is plants and their unique chemistry that are responsible for the conversion of a mineral's electro-magnetic charge from positive--found in rocks and Clays, to negative found in all plants. Minerals are absorbed by plants in their free positively-charged dependent ionic state. A plant’s root hairs are the sites of absorption of nutrients from soil and water. Because of chemical processes in the plant during photosynthesis which involve chlorophyll, the positive electromagnetic charges on the minerals are changed to negative.

You now understand why humans were intended by nature to derive their minerals by eating plants as opposed to rocks and dirt!

The electromagnetic charge of organic sourced colloidal minerals is one the most important factors affecting the rate of intestinal absorption. Competitors of organic-sourced products have recently confused this complex issue of electromagnetics by stating that the human intestine is negatively charged and, therefore, negative minerals would be repelled rather than absorbed. Perhaps the following explanation will clear this misunderstand…

All living cells - and the cells of the intestine are no exception - produce an electrochemical gradient which is positive on the outside and negative on the inside due to the action of the sodium-potassium pump. There has been some questions about this since some of the physiology textbooks state that the wall of the intestine is negatively charged. The covering of the intestinal wall, the endothelium, is, according to the textbooks, negatively charged due to the fuzzy coat of hyaluronic acid which is a mucopolysaccharide. However, this negative charge only occurs when the pH is 7 (neutrality). At a pH of 7, the carboxyl groups of glucuronic acid, a monosacchride of hyaluronic acid, is completely ionized creating a negative charge at the intestinal wall.

The problem with this theoretical explanation of why the intestinal wall may be negatively charged is that a pH of 7, neutrality, is simply incompatible with life!

As living organisms, we have millions of chemical and enzymatic processes going on at all times. Our body fluids are, at any moment in time, at various points in the body: either a pH of more than 7 (alkaline) or a pH of less than 7 (acidic). At pH's other than 7 (neutral), all living cells, as discussed above, produce an electrochemical gradient which is positive on the outside. Therefore, negatively charged plant derived minerals are attracted to a greater extent than their positively charged inorganic counterparts.

The reason for the lower absorption percentage for inorganic colloidal minerals, as compared with organic colloidal minerals, can now be understood. It is due to the fact that these type of colloidal minerals sourced from inorganic soil and clay, whether chelated or not, have a positive charge. The intestinal wall has an extracellular charge which is positive. Like charges repel one another, thus impeding absorption. The positively charged intestinal wall attracts particles that are negatively charged. Since opposite charges attract there is a much greater absorption of plant sourced colloidal minerals.

What About Toxicity

This brings us to a discussion of those minerals which may be toxic in certain forms. Due to the extensive pollution of our environment at virtually every level, consumers are being bombarded with warnings about the toxic effects of metals such as aluminum, cadmium, lead, mercury and others. In their inorganic base state, these elements can seriously compromise an individuals health status.

Because the body has no effective way of dealing with these substances when they are in their inorganic state, they are often stored in the soft tissues of the body because an elimination pathway cannot be found. Unfortunately opponents of colloidal broad spectrum mineral products point out that they contain the so called toxic minerals. What these 'marketers' of other products don't tell you is that not all colloidal minerals are the same: organic colloidal minerals have absolutely no Toxicity whatsoever because they cannot be stored by the body for longer than a few hours. For a further discussion of this subject please refer to our special report entitled, "Not All Minerals Are Created Equal," available from the Institute of Nutritional Science.

Let's take one mineral, aluminum, as an example. This element, in its inorganic base metallic form, has been linked to a variety of health concerns. Yet since aluminum is one of the most prevalent elements in nature it may be found in quite high amounts in most of our foods. Jonathon Wright, M.D. in a recent seminar entitled, "Nutrition Therapy in Medical Practice", indicated that certain fruits and vegetables such as bananas. cucumbers and tomatoes have very high amounts of organic aluminum which they naturally take up from the soil.

Why is no one worried about an overdose of aluminum from bananas?

The answer is simple: aluminum has always been a normal, natural constituent of many healthful foods! It therefore seems to us that all the hysteria about aluminum in organic colloidal products has simply been generated by individuals who either have no knowledge of food science or have a special interest to fulfill such as the promotion of their own product.

The Oldest Nutritional Supplement Ever Sold

What we must remember is that natural organic sourced liquid mineral products are the oldest nutritional supplement commercially sold in the United States. These products have been sold to the public via various venues since the early l930's. Hundreds of thousands of people have taken these products for a lifetime and yet after numerous generations of consumption, no one has reported any toxicity or other detrimental effects from their use'

In fact research done primarily in Germany and other European countries has shown that minerals in this natural form not only nourish the body with over 70 natural elements present in all healthy humans, but also actually demonstrate therapeutic benefits-- such as being able to naturally remove heavy metal or toxic metal counterparts lodged with the soft tissues of the human body. For more on this subject please refer to the study shown in The Institute's Special Report entitled, "Not All Minerals Are Created equal", available from the Institute of Nutritional Science.

One final comment regarding liquid organic trace minerals. It has been implied by many marketing people that these products provide adequate amounts of all the minerals your body needs.

This is simply not the case!

All liquid trace mineral products are just exactly that, trace mineral products.

Yes, they do contain the major minerals such as calcium, magnesium, potassium etc., but only in trace amounts. In order to receive the necessary amounts of these major minerals you need to take a product that provides them in the amounts required by the body. Furthermore the body needs about 100 nutrients every day of its life.

In order to meet that need for vitamins, major minerals, trace minerals, fatty acids and amino acids, it is necessary to include a full spectrum program that can deliver all of the nutrients in the right ratio to each other! The companies that offer only a trace mineral product are not giving you everything your body needs. In fact, they may be simply trying to capture a piece of the commercial wave of interest in liquid trace minerals and do not necessarily have your good health in mind.

When selecting a nutritional company, we urge you to pick one that not only offers good, high quality products but goes the extra step to provide you with the knowledge and education necessary to incorporate these products into a lifestyle program that will serve you and your family for all the good years ahead.

Nutrition is only as sound as the research behind it. Beware of those who criticize others only to have another product in the shadows that, by strange 'coincidence,' is better according to them.

Your health and the health of those you care about is not to be gambled with. Seek the facts then ensure that each and every member of your family is receiving the right full spectrum combination of products for their individual needs. You will be rewarded ten-fold for your efforts.
