Creatine monohydrate does not affect kidneys
I recently received a question from a reader whether supplements would cause side-effects.
My emphatic ‘no’ for answer had scientific backing.
I now offer one of the research reports I recently came across.
Creatine Monohydrate, a 100 % legal supplement used for strength and mass gains, is considered harmful to kidneys by many.
Brazilian researchers conducted a study in which test subjects were given 10 gm a day of creatine monohydrate for three months. The supplement had no harmful effects on kidney functioning in the subjects, who also performed cardio training for 40 minutes, thrice a week. Researchers found that Cystatin C, a marker of kidney dysfunction, had decreased in the creatine and placebo (fake creatine) groups, showing that workouts improved overall health of the kidneys.
The study has concluded that creatine monohydrate does not harm kidney functioning.
