The process of Chelation is first found within the chemistry of the earth, of the soil itself, where most minerals (through special microbial action) are dissolved from rock, sand and other inorganic materials. These dissolved minerals are then joined (through rain, compaction, etc.) with organic decaying matter rich in Amino Acids. The organic matter within the soil provides a medium for chelating (and holding in available form) dissolved inorganic soil nutrients needed by plants. Many minerals are then absorbed by plants in Chelated form. And soon after, plant metabolism then provides us with minerals in Chelated form almost entirely, including all of the trace elements.


This is nature's way, a way proven to be most efficient and effective. And Chelation is not only the preferred means of mineral absorption and transport in plants, but also within mammals. Although mammals and other animals are a little more flexible than plants, and can absorb non-Chelated minerals, they do so at a much slower rate and depend upon many other factors, which in turn, can affect "what" and "how many" minerals may finally be assimilated by the body. This is a basic biological fact well studied and documented.


The process of Chelation also occurs naturally in the gastrointestinal tract with the help of Free Form Amino Acids. Again, this is a very simpe, yet extremely effective process wherein a molecule of a mineral is physically encased and surrounded by a molecule of a Free Form Amino Acid. This is the natural process whereby the majority of all minerals, be they free, colloidal and/or ionic, can be quickly absorbed into organic mechanisms.


As minerals are consumed and extracted from the foods we ingest (or the supplements we take), they pass from the stomach into the duodenum mostly in their free ionic state. Here, within this chemical-rich environment, minerals may become naturally Chelated by Free Form Amino Acids and free peptides. Once Chelated, they are then immediately prepared to proceed through the epithelial cells of the muscosal lining of the duodenum into the blood stream. The critical point where this process can break down is whether or not there are sufficient numbers of Free Form Amino Acids within the duodenum for Chelation to take place. If minerals are not naturally Chelated, they must remain within this environment awaiting the passive tidal flux of ionic transport before they can be transported into the blood stream.


More specifically, the body has a slight problem when attempting to quickly absorb Raw Mineral Complexes of salts and alkaloids (eg., MgSO4), Free Ionic Minerals (Cu2+, Fe2+/3+, etc), and/or Colloidal Complexes. (Colloidal minerals are simply mixtures of raw mineral salts, alkaloids, and ionic minerals in a liquid suspension or dried within a loose flux.) Without Chelation, these minerals can only be absorbed by the body by energy-dependent driven and passive diffusion processes, a much slower and less guaranteed process of absorption than for minerals which have been naturally Chelated. Moreover, these unChelated minerals must all compete with many of the same mineral uptake sites in the mucosa lining of the gut, slowing the process of "tidal infusion" even further.


On the other hand, Free Form Amino Acids become ionized molecules in aqueous solutions, such as the gut, naturally having a resting electric potential and capable of responding to the alkalinity and acidity in the medium in which they are found. Because of this they are called isoelectric (isoelectric pH or pI) and demonstrate free active migrational tendencies according to the pH of the gut. Amino Acids are also zwitterions or dipolar ionic molecules which bear charged groups of opposite polarity, and thus exhibit properties of ionic compounds, being more soluble in polar than nonpolar solvents.
