My niece wants to try Herbalife shakes to lose some weight for this summer. I’m still trying to piece information about this stuff online to see if Herbalife is good enough to use or not. I was really hoping someone can help me figure out if their shakes causes kidney stones though. Her mother had kidney problems when she was alive, so I’m really not sure about this stuff if it’s true. I don’t want my niece to have to go through that if these shakes make her develop kidney stones. Any advice or suggestions would be great. Thanks in advance.
