Is Creatine Bad for the Kidneys?

It’s a tough question. Creatine certainly taxes the kidney (that is, makes them work), but can it cause them any long-term harm? Ironically creatinine (which is a break-down product of creatine phosphate) can be used to determine overall kidney health.

I used to be a body builder, and am no longer one due to various reasons. Creatine did not stop me (it was not the last straw), but it did cause numerous side-effects when I was on it. Nothing terrible, but we’ll start with the bad effects first…Ordered least to most severe:

  1. Gas and indigestion (got better after I was on for a while)
  2. Irritability and hostile – almost enough to make me start fights (my mother complained of #2 during the holidays so take it with a grain of salt)
  3. Heaviness in my legs (water retention?)
  4. A heavy feeling in my heart/chest

Well Did it Work?

I noticed it after the first few weeks, it was an impressive step up. I would probably say I got 25% more out of a workout due to creatine. Remember I said (above) that the creatine made my legs heavier? Well, they were also STORNGER, I could bike up steep hills like a locomotive.

I really didn’t like #4 though, I don’t like anything that messes with my heartrate. I’m a skinny guys so I feel skipped beats, etc really easily.

I don’t take creatine now, but if I did, I would really listen to my body to see if I felt good on it. Even though creatine is generally considered safe (even for kidneys), we are all individuals and need to listen to our bodies’ warning messages. If you feel crummy, don’t spoon it down!

Wishing you buff dudes the best!
