"The National Institutes of Health recommends copper supplements, like Colloidal copper, as a treatment for copper deficiency. While rare, copper deficiency can be found in infants fed cow-milk formula exclusively, those born prematurely or with low birth weights, or those suffering from malnutrition. It is also prevalent in children with cystic fibrosis and adults with celiac disease, each of which interferes with the absorption of minerals in the digestive system."
"A colloid is a substance that is said to be dispersed throughout a different substance evenly on a microscopic level. Colloidal systems normally have two different phases, a dispersed and a continuous phase. Copper colloids consist of nanometer particles of pure copper in a fluid."
