Protein and Creatine Safe for Healthy Kidneys

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.
