1 Dietary Phosphorus Restriction for Control of PTH in CKD Guideline 4.1. Restriction of Dietary Phosphorus in Patients with CKD  Dietary phosphorus should be restricted to mg/day when the serum phosphorus levels are elevated (>4.6 mg/dL [1.49 mmol/L] at stages 3 and 4 of CKD. Commentary  “The available data and the opinion of the Work Group support the proposal that dietary phosphate restriction should be initiated when blood PTH levels begin to rise (Stage 2) and/or when serum phosphorus levels are elevated at any stage of CKD.” Adapted from National Kidney Foundation. Am J Kidney Dis 2003;42(4 suppl 3):S2-S201.
