Remember that it is not what you put into the body that is important, it is what you put into the body that can be assimilated and made bio-available. The first type of mineral you could introduce into your body is a metallic mineral. Metallic minerals come from ancient sea beds and ground up rock and soil. Metallic minerals are classed as hydrophobic. They have a positive electrical charge and they represent sparingly soluble minerals with an inherent resistance to interaction with water. Basically this means most of them are not water soluble and hard to dissolve. According to numerous nutritional experts, the body can assimilate no more than 8% of the metallic minerals it consumes. This is the type of mineral that is found in most mineral supplements you buy at the grocery store. Let's assume that you wanted to take 100 mg of a specific mineral each day. If you are using a metallic mineral supplement, it is possible that only 8% or 8 mg would be available each day for your body to really use. The health food industry recognized the absorption problem years ago and developed the chelated mineral. A chelated mineral is nothing more than a metallic mineral that has been wrapped with a protein or amino acid which helps dissolve the metallic substance. This chelating process increases the assimilation or absorbability. However, a chelated mineral is still a metallic mineral that requires digestion before providing nutritional benefit. The third type of mineral you can introduce into your body is a plant derived hydrophilic mineral. Hydrophilic minerals originally came from the earth through the root of a plant. They consist of macro-molecular organic matter and polymeric precipitates because they have been digested by the plant. A hydrophilic mineral has a negative electrical charge and forms direct hydrogen bonds with water. Therefore it is water soluble and easy to dissolve without digestion. Almost 100% of a hydrophilic mineral is assimilated by the body and is made bio-available for the body's use. Generally, hydrophilic minerals are from 200 to 2,000 times smaller than metallic minerals. According to several well-known scientists, some of the minerals in TRC Minerals? may be no larger than 0.0001 micron. This small size permits them to be absorbed through the skin or by the hair shaft.
