Is Protein Powder bad for your kidneys?

No, protein powder is not bad for your kidneys. There is no existing evidence that too much protein can damage kidney function in adults. High protein meals can increase pressure inside your kidneys as they filter more blood than usual, but this is a normal function of kidneys.

That said, there is evidence that a high protein diet can be harmful for those with existing kidney disease. We recommend consulting a health professional if you wish to use protein powder and have an existing kidney condition.
