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.
