I was looking on the net to get info on diatomaceous earth and if it was harmful to kidneys, and came across this page. I have PKD and have to be careful with what i take for my kidneys. I have been taking Bamboo supplements for my hair and had great results. i have never saw any kidney effects when i have done bllodwork from the bamboo. thank u for the info. Do u think the diatomaceous earth is ok to take with a kidney disease and should i stop the bamboo while on it, because they are both silica? Thanks in advance.
