Copper has been used for thousands of years for health and longevity, and is one of a short list of absolutely essential metallic elements in the human diet for normal metabolic processes. It's a workhorse element, working in conjunction with other elements, minerals, acids and nutrients, both to balance and potentiate their functioning.
This form of nano-copper is made by sending 220,000 and 250,000 volts of cool direct current electricity through the pure metal and into the pure water, creating nano-crystalline particles in monodisperse suspensions at 100+/- ppm. A monodisperse suspension is, in our case, an aqueous (water solvent) solution containing elements where each particle is the same size, shape and distance apart, also referred to as homogeneous. All of these nano-element products are 100 ppm.
