MINERALS

• constitute very small fraction of body weight and diet
• vital components of wide variety of body form and functions - from

bones to muscles to all organ and tissue enzyme functions

DESCRIPTION

• present in animal and plant tissues in "naturally chelated " form;

attached to organic components like sugars, proteins, vitamins and other organic acids

• traditional source of animal mineral supply

• intensified animal productivity increased animal mineral

requirement and intensive/monoculture feed crop production depleted soil mineral content to such a levels that traditional sources can not meet requirement

Extensive Intensive

> inorganic mineral supplements used to fill gap

RECENT STUDIES HAVE SHOWN THAT

INORGANIC MINERAL SUPPLEMENTS ARE NOT ABSORBABLE AS EXPECTED (<20% bioavailability)

> VERY HIGH LEVELS OF UNABSORBED MINERALS IN THE MANURE/EFFLUENTS >SIGNIFICANTLY CONTRIBUTE TO FOULING UP OF SOILS AND WATER BODIES BY EFFLUENTS

SCIENCE CAME UP WITH AN EFFECTIVE YET ECONOMICALLY VIABLE SOLUTION

MINERAL CHELATION

FATE OF INORGANIC MINERALS IN THE DIGESTIVE SYSTEM

STOMA MACH pH pH

In a normal stomach, the pH is 2-3.5. Acid pH is necessary for the activation of gastric enzyme pepsinogen to pepsin, responsible for the initial digestion of proteins.

INTES ESTINES NES STOM OMACH CH LIVER ER

In the first part of the small intestines (duodenum) , bile from the liver/gall bladder enters, and causes pH to rapidly elevate to alkaline (pH 7-7.2). The alkaline pH in the intestines is necessary to activate the

SUMMARY : INORGANIC MINERAL INTERACTIONS IN THE DIGESTIVE SYSTEM Inorganic mineral salts disassociate at gastric pH (2-4), and precipitate at pH 5. More than 85% of minerals fed form precipitates at intestinal pH of 7-7.5 Interact with vitamins (especially Vit C and A) significantly reducing vitamin bioavailability Highly active Buffering of gastric acid > elevated gastric pH > reduced protein digestion (ex. 1% calcium carbonate in diet increases the gastric pH from 3 up to 5) Mineral precipitates form viscous magma which inhibit intestinal absorption processes and initiate intestinal distress Inorganic iron supports growth of harmful intestinal bacteria Increasing the dose of one in an attempt to correct a deficiency or for other purposes negatively affects absorption of the other/s

Interaction of Inorganic Minerals in a Biologic Environment

INCREASING THE DOSE OF PARTICULAR INORGANIC MINERALS TO MEET/ CURE DEFICIENCY SYMPTOMS OR FOR ANTI-DIARRHEAL OR AGP MIMICKING REASONS MERELY INCREASES THE NEGATIVE EFFECTS The mode of action of high doses of zinc oxide and copper as antidiarrheal or as AGP like , is by inhibiting iron absorption by infectious microbes and thereby inhibiting their multiplication. But at the same time iron absorption by the animal is also inhibited - likely to be more harmful than beneficial INTERACTIVE EFFECTS OF EXCESS SUPPLEMENTATION EXCESS Calcium depresses phosphorous, zinc and iron absorption Phosphorous depresses calcium, zinc, manganese and iron Zinc depresses copper, iron and calcium absorption Iron depresses phophorous and calcium absorption Copper depresses iron and zinc absorption

Standard Mineral Bioavailability estimates are expressed as a percentage of a recognized standard and do not refer to percentage absorbed and retained. Absorbed and retained mineral as a percentage of intake is usually under less than 50% of the intake. (Minerals; Nutrient Requirement for Swine. USNRC release 1998)

UPON ABSORPTION OF MINERAL IN THE SMALL INTESTINES - TO PORTAL CIRCULATION – TO LIVER “MINERAL POOL” FOR PROCESSING PRIOR TO RELEASE TO THE BLOODSTREAM

DEPENDING ON THE TISSUE NEEDS, in the liver: IONIC METALS ARE CHELATED TO FINAL FORM LIGANDS (specific amino acids & vitamins) METALS ALREADY ATTACHED/CHELATED TO NON- FINAL FORM LIGANDS ARE DETACHED AND METAL GOES TO POOL - EX. ZINC METHIONINE METALS ALREADY CHELATED TO FINAL FORM AMINOACIDS ARE COMPLETED PRIOR TO RELEASE TO THE BLOOD STREAM FINALLY TO THE TISSUE REQUIRING THEM

SOLUTION

REACTIVE APPROACH

• Inhibit interaction with gastric ph
• ther organic materials
• avoid precipitation at intestinal PH
• add acidifiers

LOGICAL/BIOLOGICAL APPROACH

• Imitate NATURAL CHELATION of minerals

MINERAL CHELATION

• Chemically attaching minerals, using a catalyst (AN ENZYME), to an organic

acid (called a LIGAND) such as amino acids, sugars, fats, vitamins, etc., For the purpose of preventing interaction with gastric acids, intestinal ph, vitamins and

• ther organic acids and improving absorbability and bioavailability

Example: catalyst Amino acid -

• Amino acid

+ + iron Iron-amino acid chelate ligands supply the 2 electrons and bonding process utilizes an enzyme catalyst forming a coordinate covalent bond A “WET PROCESS” AS WHAT OCCURS IN NATURAL CHELATION

Coordinate Covalent Bond

Effects of Chelation

• 1. Chemically binds the positive valence of the metal to the

negative valence of the ligand > resulting complex is non- reactive to ph changes and to other organic materials (vitamins, phytic acid, etc) in the gut

• 2. Helps preserve vitamins and other nutrients which will
• therwise be precipitated with the minerals and rendered

inabsorbable

• 3. The mineral assumes the inherent solubility and absorbability of

the ligand IN EFFECT - the intestines absorb the ligand and with it the Mineral

• 4. Drastically improves bioavailability of the minerals

LIGAND SELECTION CRITERIA

• 1. Must be highly soluble and absorbable in a wide ph range
• 2. Must produce a stable bond with the metal
• 3. Must not react with other organic materials and to pH

changes in the gut

• 4. Must be one, two or all of the components of the FINAL

FUNCTIONAL FORM of the metal in the body – faster utilization and maximized bioavailability

FINAL FUNCTIONAL FORMS OF MINERALS IN THE BODY

Metalo-organic chelates as existing in the body are made up of one, two or all of the three aminoacids – glycine, cysteine and glutamic acid - plus a vitamin as cofactor.

Chromium, for example, in the final form of Glucose Tolerance Factor(GTF), is composed of Cr + glycine + cysteine + glutamic acid + nicotinic acid Selenium, as Glutathione Peroxidase (GPX) is composed of Se + cys (+ gly/glut) + Vit. E.

DEFINITIONS AAFCO 1987

Metal-amino acid chelate - Product resulting from chelation

• f a metal salt with amino acids with a mole ratio of 1 mole of

metal with 1 to 3 moles of amino acids to form coordinate covalent bonds. The average weight of the hydrolyzed amino acids must be approximately 150 and the resulting chelate must not exceed 800. Metal (mineral) proteinate - Product resulting from chelation

• f a metal salt with amino acids and/or partially hydrolyzed

protein

METAL CHELATES USING EDTA, NTA and gluconates AS LIGANDS provide effective chelation BUT animal bodies have been shown to be unable to extract the metals from the chelates, such that even if absorbed into the blood, such chelates are apparently excreted intact. (Bates et.al.1972) KEY WORDS FOR MINERALS AND CHELATES: SOLUBILITY BIOAVAILABILITY - ABSORBABILITY, TISSUE RETENTION & UTILIZATION

DRY BLENDS & COMPLEXES

• Metals and ligands simply mixed together
• relies on natural physical attraction between the (+) valence of

the metal with the (-) valence of the ligand (as in a magnet)

• forms a SIMPLE IONIC BOND
• physical bondings weak and break in acidic gastric medium
• incomplete bondings - still partly reactive > lower absorbability
• falsely passed on/sold as chelates
• minor improvements over inorganic minerals and do not

provide the benefits of true chelates

• usually described as "mineral complex"
• ratio of metal content over ligand is usually below or well

beyond what is chemically prescribed/possible for the specific chelate (ex. 15% iron proteinate with 15% iron but only 20% CP)

• usually come with a precaution “Do not use with organic

solvents“ as such complexes invariably separate upon exposure to such solvents

Yeast based CHELATES

yeast grown in culture media (solid state or fermentation vat method) with high metal and methionine concentrations the bioavailability of the metal chelate, being inside the yeast cell is subject to the digestibility of yeast cell wall (typically <20%) the bio-uptake of the metal by the yeast is subject to the biologically toxic concentration level of the metal (and therefore the product’s maximum possible metal concentration) which is typically an LD50 of below 0.1% (0.01% to 0.08%)

METAL (i.e. Zn, Cr, Se) METHIONINE CHELATES

The amino acid METHIONINE – although a choice ligand like

• ther amino acids, does not form any part of the final

functional form of metals. Thus, it needs to undergo the process of detaching, then re- attaching of the metal to final form ligands in the liver before it is finally available for use by the body – just like other inorganic minerals

THE EVOLUTION OF MINERAL - AMINO ACID CHELATE

In 1996 - Better equipment and newer processes enabled economical full use of single amino acids as ligand

• further development of the proprietary 3 stage

chelation process assured complete chelation a) enzyme catalyzed wet chelation process b) allowed use of final functional form composite amino acids to trivalent metals like chromium (i.e glycine, cysteine and glutamic acid ligands for chromium as final form GTF) c) creates a coordinate covalent bond which effectively resists uncoupling effects of gastric pH resulting to unparalleled solubility, absorbability and maximized mineral bioavailability

Intestin stinal Wall Iron amino acid chelate can not be used by bacteria as their siderophores can not attach to the iron, thus effectively limiting bacterial multiplication and colonization and resultant diseases Studies on E.coli population in the jejunum of piglets have shown that inorganic iron supplemented piglets have more than 80 times the E.coli count than pigs supplemented with NUTREX Iron Amino Acid Chelate.

DIFFERENTIATING TRUE CHELATES FROM DRY BLENDS AND INORGANIC MINERALS THRU SPECIFIC ASSAY PROCEDURES The standard mineral assays detect and measure the total free/reactive metal ion in the sample i.e. The amount of reactive metal present in inorganic mineral and incompletely bonded dry

• chelate. It cannot measure non-reactive metals in true chelates.

The AAS detects and measures all the metals present in the sample, free or bound, inorganic, organic, dry blend and true chelates. AAS can not differentiate Inorganic from true chelates, and may not be sensitive enough to measure true chelates

Inductively CoupledPlasma (ICP) is a specific test for true chelates, and can differentiate inorganics/complexes from chelates.

2ND TEST to differentiate true chelate from complexes, blends and simple proteinate mixtures

HPLC - High Performance Liquid Chromatography

true AMINO ACID chelates will have signature SINGLE PEAK profiles. INORGANIC MINERALS WILL NOT SHOW PROFILES WHILE complexes, blends and simple mixtures will SHOW MULTIPLE PEAK HPLC profiles
