Phosphate is a mineral that helps develop and repair bones and teeth. It also contributes to nerve function and muscle contractions. The body needs phosphate on the cellular level to provide energy, form cell membranes, and as a component of DNA. Hyperphosphatemia means the amount of serum phosphate or phosphate in the blood is too high. This condition most often occurs as a symptom of other medical issues.
The small intestine absorbs 60 to 70% of all phosphate taken from foods and amounts to approximately 1000 to 1500 milligrams of phosphate absorbed each day. Vitamin D increases the efficiency of phosphate absorption, but it isn't essential. The body stores phosphate in bone; this reservoir fluctuates because there is a constant flow in and out.
