Bio-elements are the elements that are used to make the numerous chemical compounds that make up live beings. Only 16 of the 92 naturally occurring chemical molecules are bio-elements, and only 6 of these 16 make up 99 percent of the entire mass in the human body. Oxygen is 65 percent, carbon is 18 percent, hydrogen is 10%, nitrogen is 3%, calcium is 2%, phosphorus is 1%, potassium is 0.35 percent, sulphur is 0.25 percent, chlorine is 0.15 percent, sodium is 0.15 percent, magnesium is 0.05 percent, and iron is 0.004 percent. Some elements like Copper, Manganese, Zinc and iodine are present in Traces.
