I've got polycystic kydney (v) and i'd like to know how edta calcium disodium could imbalance my ionized calcium and/or sodium in oral chelation ?

Binding: Edta is well known to bind certain anions. Oral chelation is not advised for pckd. I would direct your question to your nephrologist who would be most knowledgable regarding this matter.

See answer: Edta is safe when used as a prescription medicine for the correct indications. Edta can cause abdominal cramps, nausea, vomiting, diarrhea, headache, low blood pressure, skin problems, and fever. It can also cause kidney damage, dangerously low calcium levels, low potassium and magnesium levels, and even death. You should seriously discuss any planned use(s) with your nephrologist.
