My 2 cents on creatine. It's the only supplement that I felt really had a muscle building benefit. I was stronger on it and had better pumps. Also thought I was retaining a little water using it.
Having said that my kidney tests came back bad when I was using it. Doc told me to go off it and my kidney tests came back perfect. Was the high Creatinine levels due to muscle breakdown from lifting hard; kidneys failing or the supplement converting from creatine to creatinine?
Its the conversion of creatine to creatinine.
Creatinine is a marker for poor kidney function in otherwise healthy people, but if your taking a supplement that artificially raises creatinine levels, thats why.yours were elevated. Not because your kidneys were failing.
