Kidney Enzymes and Dehydration

“I started taking creatine. I weight-train and follow a bodybuilding diet (John Parrillo). I am very muscular, very strong in relative to body weight, and very defined. This is my 2nd time around in the gym after a long time away after the birth of my last child. Well, I must have been a little too gung-ho, too much heavy training, too much high protein dieting, too much creatine intake and NOT ENOUGH WATER, because my (BLOOD) kidney function tests came back too high as did my BUN levels.”

“I think creatine is great and I know it works, but please caution others on excess.”

Kidney Stones and Dehydration

“Great source of information on creatine. I just wanted to add my own experience. You may post this on your website if you wish.”

“I am a 29 year-old male and I have used creatine on and off for about 4 years. I am a competitive (Master’s) swimmer and I supplement my swimming workouts with some weight lifting. I typically only swim competitively for 4-5 months out of the year and then lift weights regularly in the off-season. During the first 3 months of using creatine I had a tremendous increase in strength and size. I literally went from being 148 lbs. at 5’10″ to 173lbs. in 3 months! Many people who saw the rapid transformation even thought I was using steroids. At that time I was in the gym 6 days per week for 90 minutes to 2 hours per day and I was also increasing my caloric intake to at least 4000 per day as well as focusing on getting enough protein. Since then, my life has gone through numerous changes that had me in and out of the gym, in and out of the pool, and on and off of creatine. I used creatine during swimming as well, but I don’t have any evidence that it gave me any kind of an edge in the pool. I just wanted to add one caution to users and potential users. BE SURE TO HYDRATE YOURSELF. The only side effect that I have had is increased propensity for dehydration. Drink more clear liquids than your body asks you for with thirst. Often times, your body is already dehydrated by the time you have a thirst sensation. I try to drink between 3 quarts to 1 gallon of water per day (especially during warmer days – my gym has no air conditioning!).”


“The reason that I bring up the dehydration point is that dehydration can lead to other problems. Back in September 2000 I suffered through the passing of a 5mm kidney stone. It was EXTREMELY painful and I wish to never experience anything like that again. Although I have not seen any direct link between creatine use and kidney stones, kidney stones are usually caused by frequent/chronic dehydration. Since creatine can increase your susceptibility to dehydration, it is important to make sure you give yourself plenty of clear liquids (water, juice, etc.) to help eliminate the body’s waste products and to keep those products from building up in the kidneys.”

“I hope my experiences help. Thanks for reading, and yes, I do still use creatine even after the kidney stone episode.”
