Brazilian researchers at the University of Sao Paulo demonstrated in 2008 that creatine had no negative effect on the kidney functioning of healthy test subjects aged between 18 and 35. A few weeks ago the Brazilians went a step further. They published a study which shows that the combination of creatine and protein supplementation isn’t dangerous for the kidneys.
Half of the men were given 20 g creatine per day for the first 5 days of the experiment. On the remaining days the men took 5 g creatine per day. The study lasted for a total of 12 weeks. The men in the control group were given a placebo.
The combination of creatine and a protein-rich diet did not reduce kidney function. And when the researchers looked at the amount of protein, urea and electrolytes in the blood, they saw no effect either.
