Inorganic constituents like macrominerals and microminerals make up 4-5% of body weight. Macrominerals include calcium, phosphorus, sulfur, potassium, chloride, sodium, and magnesium, which are essential at levels over 100mg per day. Microminerals in trace amounts include fluorine, vanadium, zinc, tin, copper, selenium, iodine, manganese, chromium, nickel, cobalt, and molybdenum. Calcium is the most abundant macromineral and is crucial for bone and teeth formation, muscle contraction, blood clotting, and nerve transmission.
