Hypophosphatemia (Low Phosphate). Hypophosphatemia may be described as low levels of inorganic phosphate in the blood. Phosphate, or phosphorous, is similar to calcium, and is found in your teeth and bones. You need vitamin D in order to absorb phosphate.The kidneys excrete (get rid of) phosphate from our bodies.
