Forum Name: Renal Failure

Question: Creatine Supplementation

 manlidher - Sat May 16, 2009 3:07 pm

Hi, Im a 18 year old male. I've recently been using creatine ethyl ester to supplement my workouts. I workout 5 days a week and they consist of mostly weight lifting.I only use 3-5 grams on days I workout. What I want to know is that can creatine supplementation increase your serum creatinine? I've heard that the half life of creatine is about a month so how long should I stay off creatine before getting a blood test or urine test done? My doctor has found my creatinine level to be higher than normal previously but I've never had pain in the kidneys, problems with urination or any other symptoms. I'm worried about having renal failure.

User avatar Hello,An interesting question.Most studies conducted are of less than 10gms perday and did not show any direct effect on the kidneys or liver but then showed some increase in serum creatinine from the very next day of intake lasting for 4to6 weeks after which they returned to normal.Ther is data that these suppliments are quite safe at levels at 3to5 gms but it is best for you to get reveiwed in view of an earlier reading of increased serum creatinine.Best wishes.
