Creatine vs Creatinine: what is the difference?
How they differ
These are constantly mixed up and one is simply the waste product of the other. Creatine is stored in muscle as phosphocreatine, a rapid phosphate reserve that regenerates ATP in the first seconds of hard effort, which is what makes it useful as a sports supplement. Creatinine is what creatine becomes when that molecule spontaneously cyclises and loses water, at a fairly constant rate proportional to muscle mass. The kidneys clear creatinine, so its level in blood is a standard measure of kidney function, and that is why a creatine supplement can raise a measured creatinine reading without anything being wrong with the kidneys. The weights differ by exactly the lost water, 131.13 against 113.12.
