I am seriously considering taking T3 only medication. Are you taking Cytomel? My urine has been foamy since I was a child, but I do consume a lot of meat. I went to an urologist, but he thought it was not a big deal because I consume a lot of protein. I've tried D-Mannose for UTI infection. Unfortunately, that did not have any effect on me. Since D-Mannose is only effective for E-Coli, what I have may be non E-Coli infection. I will see if there's a good urologist beside the one I already saw. Thanks for the input!
