There are plenty of unfounded claims out there that consuming too much protein is especially bad for your bones and kidneys. Some people even believe that overconsumption can cause osteoporosis! Nope. According to healthline.com, increased protein intake does not remove calcium from your bones, and studies have shown that it can actually improve bone health. As for your kidneys, as long as you have a healthy pair (aka not suffering from kidney disease), extra protein has not been proven to harm kidney functioning.
