What Makes Isotonix® Multi-Mineral Unique*? The two most important factors when searching for nutritional supplements are absorption and potency. The Isotonix delivery system assures the most unique way for your body to absorb the daily vitamins and minerals that it needs. This delivery system allows the vitamins and minerals to be rapidly absorbed into your body. Isotonix food supplements, when mixed with water, have the same pH and osmotic pressure as the body's fluids, such as tears, plasma or blood. When an isotonic substance enters the body, it is rapidly absorbed into the bloodstream. This is the epitome of superior delivery. Isotonix Multi-Mineral Formula provides essential and trace minerals that support enzymatic and cellular functions in all tissues. Many health professionals agree that proper amounts of minerals are necessary for optimum health. Isotonix Multi-Mineral Formula provides 14 essential minerals that aid in the metabolic process, regulation of water and electrolyte balance, in providing a sound skeleton, regulation of functions of muscles and nerves, and regulation of hormonal activities. Minerals are necessary for the utilization of vitamins.
