1 The tolerable upper intake level (UL) for phosphorus is 4,000 mg/day for generally healthy adults. 2  Yet, daily phosphorus intakes in excess of the RDA have been linked to an increased risk of all-cause mortality in healthy individuals. (More information).he recommended dietary allowance (RDA) for phosphorus is based on the maintenance of normal serum phosphorus levels in adults (2.5-4.5 milligrams/deciliter [mg/dL]) and is believed to represent adequate phosphorus intakes to meet cellular and bone formation needs (6; Table 1).
