I know some people say it is bad because it looks bad on an egfr but that only measures one side. Measure the output and all looks balanced, quit and numbers return to normal. I can't find a single study that shows real long term harm, just false panic over how it creates misleading egfr and creatinin levels. Meanwhile according to examine it is the most researched and most confirmed beneficial supplement there is with muscle and brain health benefits.
