Can You Take Creatine and Phosphorus Together?

Dose or timing may matter

The short answer

Both creatine (as creatinine) and phosphorus require renal clearance. High phosphorus intake can impair kidney function over time, and adding creatine's metabolic byproducts may compound the renal workload.

How to arrange timing

Monitor phosphorus intake from all sources (supplements + diet). Ensure adequate hydration and periodic renal function checks.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
