    I get a kidney stone once a year. It is part heredity and my diet. I have been drinking protein shakes in the morning and sometimes after workouts for a year. Lately I have been getting kidney stones more often. I had one about 2 months ago and it passed, it hurt and it was over. I ended up in the hospital last Wednesday because I had another one. The pain was the worst of all of them I have had. Come to find out, there were two of them at the same time. One passed yesterday and it was very painful. The second one was today and it hurt but not as bad. It was smaller then the first. Now my Doctor is trying to figure out why I am getting them so frequently. We did determine that I am not drinking enough water. The only other thing we could come up with was the protein shake. I am using EAS vanilla whey protein powder right now. Before that I was using gold standard vanilla whey protein isolates. I take a multiple vitamin, fish oil and vitamin D because I was d deficient last time I went to the doctor. I only drink milk in my protein shake. I have a cup of fat free ice-cream some nights. Anyway we can't figure out what else it could be. Have any of you heard of protein powder causing kidney stones? My doctor is looking up info to see what he can find and I am as well. I just thought I would ask you guys. I have learned a lot from asking my friends on Real Jock and I value your thoughts and ideas. Thanks!

    I did Ctrl+F just to search for the word "water" because that was gonna be my first question...and that is probably your answer.
    I've also read stories of liver damage, too, due to lack of water.

    I've heard of this happening with any powdered, mixed beverage. Just calcifies easier in the kidneys, I guess. But, extra water might be something to try before cutting out your protein.

    Well there's the problem.

    Perhaps drink some cranberry too, but don't replace any water with cranberry, just add lots more water and some more cranberry

    I found several articles on the Net that make the claim that animal protein (whey) increases the risk of stones.

    Supplementing with vitamin C may increase the risk for stonesicon_eek.gif

    One author suggested moderating protein intake and increasing fluids.
