Possible Interaction: Creatine and Creatinine



Research Papers that Mention the Interaction

Although the levels of creatine in each formulation were not determined, a substantial conversion of creatine into creatinine has been reported in many formulations and may explain the present findings.

Creatine supplementation resulted in greater cyst growth and worsened renal function in the Han:SPRD-cy rat, evidenced by greater kidney weights (2.87 ± 0.…; P = 0.0167) and serum urea concentrations (23.96 ± 0.92 versus 20.65 ± 1.06 mmol/L; P = 0.0230), and lower creatinine …).
