What are the side effects of creatinine?
creatinine
Creatinine is the natural metabolic product of creatine or creatine phosphate. The body cannot further utilize creatinine and excretes it completely and unchanged via the kidneys. If creatinine is ingested through food—for example, minute amounts are present in certain foods—it is absorbed by the body unchanged and excreted again. Creatinine has no benefit for the body, but it also does not harm it.
The creatinine level in the blood is generally used as an indicator of kidney function. However, since the creatinine level can also increase in connection with creatine intake and the expansion of the creatine pool in the body, creatine supplementation is mistakenly associated with a negative impact on kidney function. There is, however, no scientific evidence for a damaging effect of creatine or creatinine on the kidneys.
