How did you get the gadolinium poisoning, from contrast agent? Did you have it confirmed with any lab work?
It looks like kidneys are where symptoms manifest so I would try to do some kidney work. Maybe increase salt, parsely tea, citrulline/watermellon seed, goldenrod tea. I'm not positive if edta chelates gadolinium but if so a safe way to use it would be suppository. Have you tried something simple like ascorbic acid powder or buffered ascorbates?
There is a product called ora-chel which is edta capsules. Maybe you could try a low dose or two.
There is another remedy for Pylori but it works mainly for blood type O - fucoidin. It also works on other types but not as well. Some people find gluten free helps to kick Pylori, or it's a necessary step.
