Creatine is the safe supplement. Did you know, 90% of the athletes in the world use creatine to boost their performance. Now straight comming to the health concern.

There is some concern that it could harm the kidney, liver, or heart function. However, a connection between high doses and these negative effects has not been proven.Creatine can also cause stomach pain, nausea, diarrhea, and muscle cramping.Creatine causes muscles to draw water from the rest of your body.

But there is no scientific theory proving that creatine is bad for kidneys or liver. A common knock against creatine is that it's bad for the liver, but this doesn't withstand scrutiny. A number of human studies have looked specifically at creatine usage and liver parameters and found no association between the supplement and liver problems.
