The Truth About Minerals in Nutritional Supplements

Robert Thiel, Ph.D., Naturopath

Abstract: Even though natural health professionals agree that humans should not try to consume industrial chemicals, most seem to overlook this fact when mineral supplementation is involved. And even though many people interested in natural health take minerals, the truth is that nearly all the minerals taken are natural for nothing but sometimes plants. While plants are designed to ingest and break-down minerals, humans are not. The truth about nearly all minerals in supplements is that they are really industrial chemicals made from processing rocks with one or more acids. The consumption of this “other half” of the mineral compound is not only unnatural, it can lead to toxicity concerns. Humans were designed to eat food and to get their minerals from foods. Foods DO NOT naturally contain minerals bound to substances such as picolinic acid, carbonates, oxides, phosphates, etc. When supplementation is indicated, only supplements made from 100% food should be considered for supporting optimal health.

In a nutritional context, minerals are certain elements, such as iron and phosphorus that are essential for the physiology of living organisms to exist.

When it comes to nutrition, plants and humans differ: "a typical plant makes its own food from raw materials... A typical animal eats its food" [1]. For plants, these raw materials include soil-based inorganic mineral salts [2]. Soil-based mineral salts can be depleted through synthetic fertilizers, herbicides, pesticides, as well as repeatedly growing crops on the same soil [3,4].

Plants, with the aid of enzymes and soil-based microorganisms, can take in from soil the mineral salts that they have an affinity for through their roots or hyphae [4]. After various metabolic processes, when these minerals no longer exist as salts, they become complexed with various carbohydrates, lipids, and proteins present in the plant as part of the living organism [5]. Thus for nutrition, humans eat plants and/or animals that eat plants, whereas plants can obtain their nutrients from the soil [4]. This process is commonly referred to as the "food chain" [5].

Unfortunately most mineral supplements contain minerals in the form referred to as ‘mineral salts’. Even though mineral salts are often called “natural”, they are rocks (e.g. calcium carbonate exists as the rock commonly known as limestone) or they are chemically produced in accordance with the United States Pharmacopoeia (USP). Mineral salts are natural food for plants, they are not a natural food for humans--humans do not have roots or hyphae!

Dietary Guideline number 18 of the Weston A. Price Foundation, an organization devoted to consuming real foods, is: "Use only natural, food-based supplements" [6]. One of the standards of naturopathy agreed to in 1947 was, "Naturopathy does not make use of synthetic or inorganic vitamins or minerals" [7]. Why would naturopaths have mentioned minerals since they are 'natural'? Because even back then, most naturopaths knew that the inorganic minerals being placed into supplements were often simply industrial rocks and not foods. Little has changed in the six decades since. This chapter documents the availability, sources, and some of the chemical differences between minerals found in foods and the industrially processed mineral salts that are found in most 'natural' mineral supplements.


Mineral absorption is affected by many factors including the chemical form, structural form, existence or lack of protein chaperones, health, dietary factors, and even medications.

“Absorptive efficiency for many minerals is governed by homeostatic feedback regulation. When the body is in a depleted state, the intestine up regulates absorption of the nutrient. At the biochemical level , this regulation must be expressed by the control of intraluminal binding lignans, cell-surface receptors, intracellular carrier proteins, intracellular storage proteins, or the energetics of the trans-membrane transport…In general mineral bio-availability decreases because of many drugs, decreases with age, and in the presence of malnutrition, is associated with poorer integrity of the small intestine. Therefore, older individuals who are often taking numerous medications and who are eating more poorly than young people are at greater risk of mineral deficiencies” [8].

Chemical Differences

The basic difference between minerals found in foods and those found in industrial mineral salts is chemical.

The chemical form of a mineral is an important factor in its absorption and bioavailability…there is evidence that the form in which minerals are ingested affects absorption. For example, particle size, surface area, and solubility of a substance affects is dilution rate…In many solid foods, elements are not free, but firmly bound in the food matrix” [8].

This, of course, is not true of most minerals in supplements as they are normally industrially processed inorganic rocks (mineral salts) hence they are void of the factors found in a food matrix. Only 100% food minerals have minerals attached in a food matrix.

Minerals are normally found in food and in the body they are attached with some peptide [9,10]. When humans eat plants or animals they are consuming minerals in those forms. Humans are not supposed to directly consume soil components [1]. With the exception of sodium chloride (common table salt), humans do not normally in any significant quantity consume minerals in the chemical forms known as mineral salts. When they do, it is considered to be a disorder called 'geophagia' or 'pica' [11,12].

It is a fact that mineral salts are often called "natural", but they are not food minerals. Mineral salts are normally inorganic molecular compounds that look like rocks [13]. Mineral salts are a compound containing a mineral element, which is the mineral normally listed on a supplement label, and some other substance it is chemically bound to. Mineral salts are either rocks (e.g. calcium carbonate exists as the rock commonly known as limestone) or they are rocks that are chemically-altered. Mineral salts are natural food for plants which can chemically change and detoxify them [14]; they are not a natural food for humans, although some people do consider crushed bones and naturally-calcified sea algae, etc. as food. Minerals bound in mineral salts simply are not treated the same way in the body as are minerals found in food.

There is a relatively easy way to tell if minerals are industrial chemicals. Whenever there are two-words on a label describing a mineral, it is a logical to conclude that the substance is an industrial mineral product and not 100% food. The exception is chromium GTF (the GTF stands for glucose tolerance factor) which is food if it is from nutritional yeast [18].

Chelated Minerals

Chelated minerals are generally crushed industrial rocks that are processed with one or more acids.

Probably the biggest difference in minerals now compared to 1947 is that some companies have decided to industrially produce versions of minerals attached to peptides. Essentially they take a rock or industrial mineral salt, chemically alter it, and attempt to attach it to the mineral. This results in a mineral that is different from normal mineral salts, but does not turn the substance into a food. Examples of this include the various mineral ascorbates, picolinates, aspartates, glycinates, and chelates. It needs to be understood that since there is not a universally accepted definition of the term 'chelate', when this term is used on a label, one generally does not know if the chelate is amino-acid based or some type of industrial acid.

While it is true that humans can, and do, utilize minerals from USP mineral salts or chelated minerals, this is not as safe (or even normally as effective) as consuming them from foods (or in the case of real food supplements, food concentrates).

Non-Food Attachments, Including Some “Chelates”, Are Not Desirable

Is it wise to consume non-food minerals?

Dr. Bernard Jensen, an early 20 th century advocate of food-based nutrition, once wrote, “When we take out from foods some certain salt, we are likely to alter the chemicals in those foods. When extracted from food, that certain chemical salt is extracted, may even become a poison. Potash by itself is a poison, whether it comes from a food or from the drugstore. This is also the case with phosphorus. You thereby overtax your system, and your functions must work harder, in order to throw off those inorganic salts or poisons introduced... The chemical elements that build our body must be in biochemical, life-producing form. They must come to us as food, magnetically, electrically alive, grown from the dust of the earth... When we are lacking any element at all, we are lacking more than one element. There is no one who ever lacked just one element. We don’t have a food that contains only one element, such as a carrot entirely of calcium or sprouts totally made of silicon” [22].

It should be noted that the addition of "citric acid and picolinic acid do not appear to enhance zinc absorption" [23]. Chromium picolinate is a human-made substance, created by Gary Evans [24]; it is not a natural food. Picolinic acid is used in herbicides [17]; furthermore "picolinic acid is an excretory or waste product. It is not metabolized by or useful to the body" [25]. Scientists report, “some research groups recently suggested that chromium (III) picolinate produces significantly more oxidative stress and potential DNA damage than other chromium supplements” [26].

Concerns are being raised from various sources about the implications of intentional ingestion of inorganic substances in supplements by human beings [22,25,26]. These substances are not natural for humans to consume and a long period of consumption may cause some type of toxic accumulation [22,25,26]. Yet, many people supposedly interested in natural health are daily consuming various carbonates, gluconates, oxides, picolinates, phosphates, sulfates and other rock components that were not intended to be ingested that way. Since there are many possible negative implications associated with “the other half” of these non-food minerals [25], people truly interested in their health would be much better off consuming foods that are high in minerals or supplements made from those foods.

Jay Patrick claims to have originally developed procedures to manufacture all seven of the mineral ascorbates [21]; thus it would seem highly inappropriate to call supplements with ascorbate attached minerals 'food'.

Actually, it does not appear that any of the minerals marketed as 'chelated' are food concentrates, though there are foods which contain naturally chelated minerals, but these are normally marketed as food minerals. Even though there are some theoretical advantages to industrially-produced mineral 'chelates' as compared to inorganic mineral salts, these chelates are not natural food.

More on Bioavailability

It is well known among nutrition researchers that most essential minerals are not well absorbed; for some minerals, absorption is less than 1% [27]. "Bioavailability of orally administered vitamins, minerals, and trace elements is subject to a complex set of influences...In nutrition science the term 'bioavailability' encompasses the sum of impacts that may reduce or foster the metabolic utilization of a nutrient" [28]. Research demonstrates that the bioavailability and/or effectiveness of mineral containing foods is greater than that of isolated inorganic mineral salts or mineral chelates [e.g. 28-43]. These studies have concluded that natural food minerals may be better absorbed, utilized, and/or retained than mineral salts.

Furthermore, minerals used in most supplements do not contain protein chaperones or other food factors needed for absorption into the cell. In 1999, the Nobel Prize for medicine was awarded to Guenter Blobel who discovered that minerals need protein chaperones to be absorbed into cellular receptors. When mineral salts without protein chaperones are consumed, "It is after digestion when other mineral forms {mineral salts} have their mineral cleaved from their carriers. In this situation, these minerals become charged ions, and their absorbability becomes in jeopardy. These charged free minerals are known to block the absorption of one another, or to combine with other dietary factors to form compounds that are unabsorbable" [44]. The body must discard the residual chemicals.

Foods used in supplements that commonly provide significant quantities of essential minerals include dulse, horsetail herb, kelp, nutritional yeast, rice bran, and water thyme. These types of foods have been shown to contain not only minerals in natural food forms, but also important protein chaperones such as ATX1 and ceruplasmin [45,46]. Industrial mineral salts do not contain the protein chaperones or other food factors needed for proper mineral absorption. Furthermore, some foods also contain factors which reduce the probability of certain minerals to be toxic to the body [32,33,46]; industrial mineral salts and chelates are simply not that complete.

Quantitative and Qualitative Differences

There are quantitative and qualitative differences in food vs. non-food minerals. Table 1 lists some of them by mineral.

Table 1 Quantitative and Qualitative Differences

Food Mineral


Compared to Mineral Salt/Chelate



7 times as effective in raising serum ionic calcium levels [30].



Up to 25 times more bioavailable [31].



Contains substances that reduce potential toxicity [32,46].



Safer, non-constipating, better absorbed [33, 34].



Better absorbed and retained [35].



Not as likely to contribute to toxicity as mined forms [36,47].



Less likely to cause diarrhea or electrolyte disorders [37].



Nearly 2 times better retained [29,38].



Safer and 50% more effective [39].



Better absorption, better form [40,41].

Foods, almost by definition, are not toxic, and as mentioned earlier, can have protective factors to prevent certain potential mineral toxicities, such as those sometimes associated with copper, iron, manganese, or other minerals [32,33,46,47].

Information by Individual Mineral [n]

Some differences between food complexed minerals and mineral salts have been documented by published research and are shown by individual mineral below:

Boron “Boron complexes with organic compounds containing hydroxyl groups” [9], which is how it is found in foods. Boron affects macromineral and steriodal hormone metabolism; without sufficient boron bone composition, strength, and structure weaken [9].

Calcium “The amount of calcium absorbed depends on its interaction with other dietary constituents...The absorbability of calcium is mainly determined by the presence of other food constituents” [48]. This is one of the reasons why isolated calcium mineral salts (such as calcium carbonate) are not absorbed as well as calcium found in natural food complexes [48,49]. “Calcium carbonate, an antacid, counteracts not only the absorption of calcium, but also the absorption of iron” [11] (though its calcium absorption appears to be better with food [49]). At least one researcher has concluded that commonly used mineral salts such as calcium lactate and calcium gluconate primarily succeed in creating high blood calcium levels (hypercalcemia) instead of alleviating symptoms of low tissue calcium [50]. “Calcium has a structural role in bones and teeth” as well as in some enzymes involved with blood clotting [48]. Calcium can affect mood and blood pressure [48,51]. Clinical reports consistently confirm that dietary/food calciums [5-8] are important in the management of blood pressure. This does not appear to be the case with isolated calcium salts (the results appear inconsistent [30,52-54]). One study found that calcium in Food raised serum ionic calcium levels from 1.08 to 1.15 mmoles, but that serum ionic calcium levels were not raised with calcium carbonate [30]. Serum calcium levels affect blood pressure [52,55]. Since low bone mass is somewhat inversely correlated with high levels of diastolic blood pressure [9], this suggests that calcium from Food may be superior when hypertension issues are present. Calcium is important for optimal health as calcium deficiencies can contribute to osteoporosis, muscle (especially the legs) cramps, insomnia, mood/behavioral/nerve problems, hypertension, kidney stones, and colon cancer [52,56,57]. It appears that overdose of calcium can only occur when taking mineral salt forms of calcium supplement as opposed to food [57].

Chromium, GTF “The biologically active form of chromium, sometimes called glucose tolerance factor or GTF, has been proposed to be a complex of chromium, nicotinic acid, and possibly the amino acids glycine, cysteine, and glutamic acid. Many attempts have been made to isolate or synthesize the glucose tolerance factor; none have been successful” [58]. Chromium is not naturally found in the body in the commonly supplemented forms such as chromium picolinate or chromium chelate. “Chromium is generally accepted as an essential nutrient that potentiates insulin action, and thus influences carbohydrate, lipid, and protein metabolism” [58]. Research suggests that there is much less likelihood of toxicity from natural food complex chromium than from forms such as chromium picolinate [26]. Only 1% or less of inorganic chromium is absorbed vs.10-25% of chromium GTF [31]. Chromium GTF only comes from nutritional yeast [59].

Copper In the human body, in addition to various plasma-bound coppers, “at least one copper peptide complex” has been isolated [60]. Copper is not naturally found in the body in the form of copper gluconate or copper sulfate. “Anemia, neutropenia, and osteoporosis are observed with copper deficiency”; copper is involved in connective tissue, iron metabolism, the central nervous system, melanin pigment, thermal regulation, cholesterol metabolism, immune function, and cardiac function [60]. Copper in foods like nutritional yeast contains protective factors that reduce the possibility of toxicity issues [32,46].

Germanium Germanium is an ultratrace mineral which affects mineral composition of bone and the liver [9]. Organic germanium complexes have been shown to inhibit tumor formation in animals, yet inorganic germanium mineral salts can be toxic [9]. High intakes of inorganic germanium mineral salts can cause kidney damage [9].

Iodine Most of the iodine in the body exists in the form of iodine-containing amino acids [61]. Iodine is needed by the thyroid gland to produce thyroid hormones which influence most of the body’s metabolic processes [61]. Kelp is an excellent food source of iodine [61].

Iron Most researchers acknowledge that organic iron is better absorbed than inorganic iron [62]. The body has different mechanisms for the absorption of iron depending upon its form [63]. Iron in foods is found in an organic form. Iron is required for growth and hemoglobin formation; inadequate amounts can lead to “weakness, fatigue, pallor, dyspnea on exertion, palpitation, and a sense of being overly tired” [63]. Iron in food is safer, less-constipating (actually it is non-constipating), and better absorbed than non-food forms [33,34].

Magnesium “The percentage of absorption of ingested magnesium is influenced by its dietary concentration and by the presence of inhibiting or promoting dietary components [64]. There are no promoting dietary components in inorganic isolated magnesium salts. “Magnesium is involved in many enzymatic steps in which components of food are metabolized and new products are formed”; it is involved in over 300 such reactions [6]. Clinical deficiency of magnesium can results in “depressed tendon reflexes, muscle fasciculations, tremor, muscle spasm, personality changes, anorexia, nausea, and vomiting” [64]. Magnesium in foods is better absorbed and retained than magnesium from inorganic mineral salts [35].

Manganese In the body, absorbed manganese complexes with various peptides [9]. Manganese is predominantly found in foods in a manganese peptide complex (such as Mn superoxide-dismutase). It is not found in the body in forms like manganese sulfate. Manganese deficiency can cause “impaired growth, skeletal abnormalities, disturbed or depressed reproductive function, ataxia of the newborn, and defects in lipid and carbohydrate metabolism” [9]. It can also affect skin, hair, nails, and problems with calcium metabolism [9]. Manganese in foods is safer and much less likely to cause any toxicity compared to mined forms [36,47].

Molybdenum readily absorbed” [9]. “Molybdenum functions as an enzyme cofactor”, thus “detoxifies various pyrimidines, purines, pteridines, and related compounds” [9]; it may also affect growth and reproduction [9].

Phosphorus Phosphorus is found in plants [11]. Phosphorus salts can cause diarrhea and other problems [37]—problems that do not happen with phosphorus in foods. Phosphorus works with calcium to produce strong bones [48].

Potassium Potassium is found in plants [11]. Potassium is the leading intracellular electrolyte and is necessary for electrolyte balance, stimulating aldersterone for the adrenal glands, and blood pressure regulation [11]. Dr. Bernard Jensen seemed to believe potassium is only safe in its natural food complex form [22].

Selenium “The predominant form of selenium in animal tissues is selenocysteine” [65]. That is how it is predominantly found in certain foods. One study found that diets naturally high in selenium (daily consumption as high as 724mcg) produced no signs or symptoms of selenium overexposure while another found that exceedingly high consumption of selenium salts could induce selenium poisoning [65]. Selenium seems to support thyroid hormone production, function as part of many enzymes, and have antioxidant effects [65]. Larry Clark, Ph.D. and others have found that selenium in yeast appears to reduce risk of certain cancers [66]. Julian Whitaker, M.D. reports, “The best absorbed form of selenium, and the one used by Dr. Clark’s research, is high-selenium yeast” [66]. A study using 247 mcg/day of high-selenium yeast found that plasma selenium levels were 2-fold higher than baseline values after 3 and 9 months and returned to 136% of baseline after 12 months, whereas there was a 32% increase in blood glutathione levels also seen after 9 months [29]. Food selenium is about twice as well retained as non-food forms [29,38].

Silicon “In animals, silicon is found both free and bound” [9]. Silicon absorption is quite dependent upon the form [9]. Silicon is involved in bone calcification and connective tissue formation [9]. It is also needed for healthy hair and skin [51]. Silicon is found in foods in an organic form.

Trace Minerals Trace minerals, including “ultra trace minerals” are necessary for the proper functioning of human health [9,51]. There are many in the human body, some of which are known to be essential and others of which their “essentialness” is under investigation.Sea vegetables and certain yeasts are a good source of trace minerals [11,31,61].

Vanadium “Vanadate forms compounds with other biological substances” [9]. “Vanadium has been postulated to play a role in the regulation of (NaK)-ATPase, phosphoryl transferase enzymes, adenylate cyclase, and protein kinases; as an enzyme cofactor in the form of vandyl and in hormone, glucose, lipid, and tooth metabolism” [9]. Vanadium in foods is found in an organic form. Vanadium in food is safer than non-food forms and also appears to be about 50% more effective [39].

Zinc Most researchers acknowledge that organic zinc is better absorbed than inorganic zinc [62]. Zinc itself is generally found in the human body in ionic form [62,67]; it is often bound with albumin [23,67] or alpha2-macroglobulin [23] or exists as part of one of the many zinc metalloenzymes [23,67]. Zinc is predominantly found in foods as zinc peptide complex (such as that complexed with superoxide dismutase). Zinc is not naturally found in the body as zinc gluconate, zinc orotate, zinc sulfate, nor zinc picolinate. In humans “zinc deficiency does not exist without deficiency of other nutrients” [67]. Zinc deficiency in humans can cause alopecia, impotence, skin problems, immune deficiencies, night blindness, impaired taste, delayed wound healing, impaired appetite, photophobia, difficulty in dark adaptation, growth retardation, and male infertility [23]. Zinc in yeast-containing foods is better absorbed and is a better form for humans than inorganic forms [40,41].

Food and Food Processing

“In the historic struggle for food, humans ate primarily whole foods or so-called natural foods, which underwent little processing...The nutrient content of food usually decreases when it is processed” [68]. “Intensive animal rearing, manipulation of crop production and food processing have altered the qualitative and quantitative balance of nutrients of food consumed by Western society. This change, to which the physiology and biochemistry of man may not be presently adapted to, is thought to be responsible for the chronic diseases that are rampant in the Industrialized Western Countries” [69]. Some reports suggest that simply taking a synthetic multi-vitamin/mineral formula does not change this [70,71].

Dr. Burr-Madsen has written,


Nutrition ‑ in its most basic sense the process by which the organism finds, consumes, liberates, absorbs, and utilizes the nutrients it must have to live. Although food and therefore nutrients are seemingly plentiful, because of modern use of chemical herbicides and pesticides as well as poor air quality and bad water, the nutrients we buy in the market are very inferior. Human bodies require nutrition found in the form of plants, m eat, milk, eggs and water, but all animals get their food directly or indirectly from plants, and all plants get their food from the soil. Therefore mineral deficient soil may be one of the greatest original sources of disease in the world today.  

Real soil

We cannot appreciate enough the importance of our relationship with the land, with soil. This is particularly so in this era of artificial chemicals, artificial foods, and the abundance of artificial materials on which we have come to depend. This system cannot replace real soil and the livin g food crops it produces. Our dependence on artificial, man­made products interferes with our relationship with the soil and the natural world in general. Because of this Nutritional supplementation is necessary.  

Soil condition.

After genetics and weather, the condition of the soil is the most important factor in the nutrient content of any plant food and, indirectly, of animal foods. The soils of the world have suffered, and continue to suffer, at the hands of farming. The present food production system, while correcting some abuses of the past, inflicts on the soil a variety of new and old insults that diminish its nutrient value. Because of intensive farming, poor crop management, erosion, commercial fertilization, the use of pesticides, and other problematic factors, much of the soil in which our crops are now raised has been depleted, particularly of essential minerals.

The Human Food Chain.

The human food chain includes animals, animal products and plants, which depend directly or indirectly on the soil. Plants draw their nutrients and general health from a complex of inorganic and organic factors. Inorganic substances include oxygen and carbon, nitrogen, phosphorus, and potassium, along with iron, calcium, and an array of other minerals. The chief organic factors range from decaying plant material and animal wastes to earthworms and an amazing variety of microscopic organisms including bacteria, fungi, algae, and protozoa (Hall 1976: 134). All of these elements are important to the health and nutrient value of the crop ‑ and of the animals that feed on it.

Healthy soil.

Healthy soil is America's greatest natural resource. B ut few realize that the current state of wide spread soil erosion in North America threatens our way of life. It may be hard to believe, but only a few inches of topsoil stand between you, me, and starvation. We cannot appreciate enough the importance of our relationship with the land, with soil. What is popularly called topsoil is the rich, nutrient‑laden cover of the Earth's crust from which food crops draw their sustenance. Underneath the topsoil there may be clay, shale, or rock ‑ Substances that do not support food crops. It is only in the precious shallow topsoil that plants are seeded, germinated, sprouted, nurtured, and grown. These plants serve as food for animals on the lowest ends of the food chain. Animals that eat these plants supply food to animals on the highest ends of the food chain. Attention is important because topsoil is easily exhausted from lack of care. The best farmers replenish the soil as it is farmed. U nfor t unately, this practice has become an exception to the rule, this is particularly so today.

Depleted Soil.

When the soil becomes depleted, the plants often show symptoms of poor nutrition, much like human deficiency diseases. For example, a general yellow or pale green color (chlorosis) indicates a lack of sulfur and nitrogen and a white or pale‑yellow color iron deficiency. Some of these deficiencies are apparent enough to hurt the marketability of the crop. Most, however, are not visible to the shopper's or even the farmer's eye, and the crop is shipped to market deficient as it is. The toll that fertilization and pesticides take on the soil is wide‑reaching, ultimately including the kind of soil erosion that is now plaguing the Midwest. The most direct and immediate loss are the mineral and vita min deficiencies in the soil that are passed up the food chain to humans (it is a domino effect) [72].

Commercial food processing definitely reduces the nutrient content of food [73] and can be dangerous to human health [74]. The refining of whole grains (including wheat, rice, and corn) has resulted in a dramatic reduction of their natural food complex nutrition[11,73]; specifically the milling of wheat to white flour reduces the natural food complex vitamin and mineral content by 40-60% [73]. Food refining appears to reduce trace minerals such as manganese, zinc, and chromium [2] and various macrominerals (such as magnesium) as well [10,47]. The treatment of canned or frozen vegetables with ethylenediaminetetraacetic acid (EDTA) can strip much of the zinc from foods [11]. The high incidences of disorders of calcium metabolism [28] suggest that the forms of calcium many are consuming simply do not agree with the body (and sometimes result in calcium loss [11]).

Organically-grown produce appears to contain higher levels of some essential minerals than does conventionally (non-organically) grown produce [75,76] and appears to contain lower levels of toxic heavy metals [77]. Even if modern food practices did not affect nutrition (which they do), all minerals that humans need for optimal health do not exist uniformly in soils. “Soils in many areas of the world are deficient in certain minerals; this can result in low concentrations of major or trace minerals in drinking water, plant crops, and even tissues of farm animals, thus contributing to marginal or deficient dietary intakes of humans [68]. From a geological perspective, a few examples include iodine, molybdenum, cobalt, selenium, and boron [2,61,68]. Although humans need at least twenty minerals (over sixty have been found in the body), most plants can be grown with only the addition of nitrogen, phosphorus, and potassium compounds [2]. If other minerals necessary for human health are reduced in the soil, the plant can (and will) grow without them. This means, though, that constantly farming the same ground can result in the reduction of some of the essential minerals we as humans require for optimal health [69].


No matter how many industrially produced mineral supplements one takes orally, they will:

1) Never be a truly complete nutrient source.
2) Never replace all the functions of food minerals.
3) Always be unnatural substances to the body.
4) Always strain the body by requiring that it detoxify or somehow dispose of their unnatural structures/chemicals.
5) Never be utilized, absorbed, and retained the same as food nutrients.
6) Not be able to prevent advanced protein glycation end-product formation the same as food nutrients.
7) Never be able to have the antioxidant effects the same as food nutrients.
8) Always be industrial products.
9) Always be composed of petroleum-derivatives, hydrogenated sugars, acids, and/or industrially-processed rocks.
10) Never build optimal health the same as food nutrients.

Industrially processed minerals can have some positive nutritional effects, yet they are not food for humans. Unlike humans, plants have roots or hyphae which aid in the absorption of minerals. Plants actually have the ability to decrease the toxicity of compounds by changing their biochemical forms [14]. Plants are naturally intended to ingest rocks; humans are not [1].

The truth is that plants, or supplements only made from plants, are the best form of mineral supplement for humans, yet most people who take nutritional mineral support consume some type of industrially processed rock.
